Patent number: 11696532Abstract: A baler includes a chamber having a fixed size that receives crops and houses a formed bale. A tailgate is connected to a frame and is movable between a closed position, for cooperating with the frame to delimit the chamber, and an open position, for discharging the formed bale. A conveying assembly delimits the chamber for imparting a rotating movement to the crops contained in the chamber, and has a first portion provided in the frame and a second portion provided in the tailgate. An actuator includes a closing chamber and moves the tailgate from the open position to the closed position upon receiving an actuating fluid in the closing chamber. A binder binds the formed bale, and a pressure sensor detects a control signal representative of a pressure inside the closing chamber of the actuator. A control unit generates an alert signal as a function of the control signal.Type: GrantFiled: August 9, 2018Date of Patent: July 11, 2023Assignee: KVERNELAND GROUP RAVENNA S.R.L.Inventors: Valerio Casadei, Cosimo Frascella

Patent number: 5308933Abstract: A truck scale has a weighbridge built with two parallel beams for carrying the wheels of a truck. The beams are laterally interconnected, and are each narrower than half the width of the weighbridge, so there is a gap at the center between the beams. Each beam rests directly on load cell devices supported by foundation members. In very long scales each beam is composed of shorter sections, each supported by a pair of load cell devices. The gap in the center of the weighbridge is covered by removable cover plates or blocks, which may have side walls extending above the beams to limit the lateral travel of truck wheels on the scale.Type: GrantFiled: February 7, 1992Date of Patent: May 3, 1994Assignee: Flintab ABInventor: Nils G. Ahl

Patent number: 5170854Abstract: A T-shaped seal is disclosed for installation in the gap between a scale pit wall and a scale platform to prevent entry of foreign matter into the area below the platform. An upright stem of the seal is provided on its sides with vertically spaced ribs which may flex during installation between the scale pit wall and the platform edge. The ribs prevent upward dislodgement of the seal against all but intentional efforts and provide additional barriers to foreign material. The stem is of a flexible nature to accomodate irregular pit wall and scale surfaces. A ventilator is shown for installation within an opening formed in the flange portion of the seal and serves to permit the circulation of air beneath the platform while preventing the entry of material into the gap between the scale platform and pit wall.Type: GrantFiled: June 20, 1991Date of Patent: December 15, 1992Inventors: Mahlon W. Miller, Patrick F. Tierney

Patent number: 4832140Abstract: A platform weighing apparatus is at least partially made of polymeric concrete. With one embodiment a lost self-supporting shuttering made of polymeric concrete is used for forming the platform of the weighing apparatus and a base frame is made of polymeric concrete. With another embodiment the platform is structured with cavities and made essentially of polymeric concrete. The method according to the invention permits molding of the shuttering or the complete platform at a manufacturing site with easy transportation and assembly at an operational site.Type: GrantFiled: October 7, 1988Date of Patent: May 23, 1989Assignee: Pfister GmbHInventor: Hans W. Hafner

Patent number: 4729443Abstract: A protection and secondary checking system for a weighing scale having a scale platform which is spaced peripherally from a support to form an intervening space. The protection and secondary checking system is supported on both the scale platform and the support but is not connected to either, and includes an elongate resilient body having a central web which extends into the intervening space to orient the body and provide platform checking. A cover and mounting section extends laterally from one longitudinal edge of the web and rests on both the platform and support.Type: GrantFiled: December 17, 1986Date of Patent: March 8, 1988Assignee: Colt Industries Inc.Inventor: Joseph R.

Patent number: 4392537Abstract: The present invention relates to a weighbridge consisting at least partially of cast concrete portions, and a method of producing such a bridge. With the object of increasing the accuracy of a weighbridge, of facilitating and cheapening the production of a weighbridge, it is proposed according to the present invention that the bridge (1) should be disposed resting against two beams (5) which are disposed along the long sides of the bridge and supported by transmitter members (6), that at least two transverse beams (7) are disposed secured between the longitudinal beams (5) of the bridge, preferably at the short sides of the bridge, that the cast portions of the bridge are surrounded by an edge lining (3) preferably of sheet metal bearing downwards against the tops of the beams (5, 7), and that the cast portions preferably comprise a corrugated or profiled bottom metal sheet (12) resting substantially against the longitudinal beams of the bridge.Type: GrantFiled: June 15, 1981Date of Patent: July 12, 1983Assignee: AB Bofors ElektronikInventor: Olle G.
