Abstract: The pick-up device 1 disposed in the direction of travel in front of a harvesting machine 2 for cucumbers has a circulating conveyor belt 11 having upward jutting spikes 12 made of rubber or elastomeric plastic and further has an associated circulating cover belt 18 having upward jutting transverse moldings 22, which are tilted forward in the direction of circulation. Directly behind the place at which the spikes 12 reach with their tips the lowest point of their path of circulation, a cutting device 24 is active, which cut off the cucumber plants raised with the spikes 12. A sensing roll 30 resting on the ground 9 controls the height position of the pick-up device in such a way that the blades 27, 28 of the cutting device 24 and the tips of the spikes 12 do not penetrate into the ground 9, but always maintain a short distance from the ground. This configuration ensures an operation which is not disturbed by plant pile-up and even permits use in plasticulture.

Abstract: A plant seedling handling apparatus is described which comprises a pair of parallel belts, each of which carries a series of grippers. During loading of the storage device each belt is fed from separate storage means via guide spools which create a nip between the belts. At the nip a pair of grippers 31, 34 grip a seedling stem 36. When the movement is reversed the seedling is released as the grippers separate as the belts pass around the guide spools 24 and 25. The seedling can be released direct to a planting device.

Abstract: Apparatus for moving along rows of agricultural beds for pulling and collecting stakes therefrom. A stake-pulling element is suspended from framework attached to a wheeled collection bin and from a framework attached to a towing vehicle. A pair of endless parallel puller chains is disposed in the stake pulling element having a forward end near the surface of the bed and a rearward end elevated with respect thereto. The puller chains are driven to cause the inner runs of the chains to move upward and rearward with the rearward chain velocity equal to the forward velocity of the apparatus. Stakes are gripped between the chains, carried rearwardly and pulled directly upward to remove the stakes from the ground. As the stakes are carried to the rear of the chains, they are transferred to a stake transport belt which moves the pulled stakes to the bin and deposits the stakes therein. Operating power in one embodiment is obtained by coupling to the wheels of the collection bin.

Essentially the invention includes an inclined conveyor formed by a pair loop belts, each belt travelling between an idler pulley and a drive wheel, such that the loop belts, being composed of a resilient material such as sponge rubber, are placed in an abutting juxtaposed position to thereby co-operatively form the mechanism which pulls the plant from the ground and as well conveys the plant from the ground toward the collection receptacle.

Abstract: Leafy and woody plants are harvested by holding the uprooted plants in a guided path while they are being removed. The uprooted and removed plants are classified and counted by a counter along the path to establish a minimum standard size to which the counter responds. The plants meeting this standard are counted until the number of the counted plants has reached a set number and the counted plants accumulate in a space between the end of the guided path and a packaging device. The counter is set to operate a forked element for moving the accumulated plants to the packaging device when the set number has been reached.

Parallel mounted endless belts are supported on the frame and grip tomato plants, or the like planted in rows, and transport the plants into a loading mechanism. The plant roots are cleaned by rotatable, flexible flaps hitting the roots of the plants being transported between the parallel belts.

Abstract: A mobile device for harvesting tree seedlings includes means for subsurface cutting to separate and loosen from the surrounding ground the body of earth adjoining the roots of the tree seedlings. The movement and relative position of the earth separating means enables it to efficiently sever the roots of the tree seedlings from the surrounding ground while allowing only a minimum amount of earth to adhere to the roots of the seedlings as they are removed. A plurality of paired gripper belts remove the loosened seedlings by lifting them upwardly and rearwardly relative to the ground, each pair of gripper belts having male-female intercoupled gripping surfaces which minimize damage to the stems of the seedlings. Disposed below the gripper belts are a plurality of elongated root beater means adapted to move in a transverse oscillatory manner to agitate the roots and remove the earth adhering thereto without damaging the seedlings.
