Abstract: This invention was intended to develop an earth working equipment and system for digging holes in ground particularly in agricultural soils for needs including but not limited to transplanting of seedlings of flowers, vegetables, fruits, bushes, and shrubs; and for making holes for other purposes where hollow-cylindrical shapes are desired. One very important feature of the equipment is the provision of a removable or embeddable cylindrical retaining wall around the hole being dug thus preventing hole-deforming avalanches of soils, common in trowel assisted hole digging that results in V-shaped rather than cylindrical shaped holes. This provision and other features of the equipment ensure formation of consistent hollow-cylindrical holes effectively, efficiently and economically. The equipment consists of a tilling tool to loosen the soil, a screw conveyor to dig into and transport the soil away, and a cylindrical retaining wall to maintain cylindrical shape of the hole by preventing soil avalanches.

A second opening directs jets of liquid from the third chamber during the first time period to form holes in the ground. A second valve is operable during a second time period to regulate the first pump to transfer the particles to the third chamber. The first valve is operable during a third time period to regulate the delivery of the liquid to the third chamber through the first opening causing jets of the particles to be directed through the second opening into the holes.

Abstract: A seeder is disclosed which includes prior art elements of a bottom stationary drop plate, an intermediate and sliding reciprocating cell plate with individual singulating cells, and "wiper bars" overlying and in sliding engagement with the cell plate. The improvement herein has the overlying wiper bars apertured in registry to the underlying drop holes. The cell plate at each individual singulating cell reciprocates to and from a position of registry with and to the wiper bar apertures above and drop apertures below. Reciprocation to a position of registry typically accumulates a singulated seed in each cell of the cell plate, and thus places the seeder in position for seeding with singulation. A probe, registered to the wiper bar aperture is mounted for reciprocation relative to the wiper bar aperture. The probe is actuated in its reciprocation when registration of the singulating cell to the wiper bar aperture and drop hole is effected.

Abstract: A method and apparatus is provided for planting tree seedlings or the like. The apparatus includes an elongate tube, and a pair of blades pivotally mounted to the lower end of the tube. The blades are each pivotal between a closed position closing the lower end of the tube, and an open position wherein the lower end of the tube is open. In use, the lower end of the tube is rotatably advanced into the soil, with the rotating blades acting to pulverize the surrounding soil. Also, the blades will be pivoted to the closed position by the resistance of the soil, to prevent the soil from entering the tube. A seedling is then deposited downwardly through the tube, and the tube is rotated in the reverse direction to withdraw the tube from the soil. During reverse rotation, the blades pivot to their open position to permit the tube to lift from the seedling, and act to press and compact the soil about the roots of the seedling.

A cam interrupts the vacuum by compressing the hoses when the seed-bearing apertures contact the seedbed, thereby releasing the seeds and pressing them into the soil. The seeds are preferably placed on the seedbed in a uniformly spaced array predetermined by the uniform alignment and spacing of the apertures on the wall of the drum.

Abstract: A planter is moved through a field to place two rows of four plants on the top of a planting bed between adjacent irrigation furrows. The tray carrying the transplants is registered horizontally and vertically to a plug receiving cylinder by respective cams and a supporting chain. Upon registry, polymer plugs containing sprouted plants therein are ejected, typically eight at a time, by ejecting fingers penetrating the plant receiving holes. Ejection occurs with the plants horizontally disposed into receiving concavities defined within a rotating cylinder. Rotation of the cylinder drops the ejected plants into receiving funnels, one for each plant. Plant downward travel halts at a reciprocating plate. Insertion of the plug into the ground begins with penetration of the ground by a dibble spike followed by circumscribing penetration of a dibble tube around the spike.
