Description

Known transplanting machines that have openers, hares, landing gear, made either in the form of an endless chain with clips, or in the form of wheels with hanging baskets, as well as a irrigation device, as working bodies, and with a complicated design, only the planting process is mechanized. in the ground of plants or peaty pots with seedlings, without ensuring the mechanization of the processes of sampling seedlings from the greenhouse In the proposed self-propelled machine, this disadvantage is eliminated by the fact that, for the purpose of complete mechanization The harvesting and picking of seedlings, its selective-picking apparatus is made in the form of two consecutively located disk cutter drums with radial slits on the disks, which include knives fixed to the frame and its frame, reciprocating from the crank mechanism .

FIG. Figure 1 shows the layout of the working parts of the machine and gear mechanism; in fig. 2-machine when sampling seedlings, side view; in fig. 3 - machine for picking seedlings, side view.

The machine is mounted on a self-propelled chassis, I have a rubber-crawler crawler 1. In the middle of a rigid (main) frame 2, the working frame 5 is pivotally suspended with working bodies. A folding lift 4 for laid seedlings is installed in front of the frame, and inside the frame there are two drums of 5 hours 6 offset from each other in the longitudinal and transverse directions. Each drum consists of a set of steel discs with peripheral radial cuts 7. These cuts include knives 8 mounted on a common frame for each drum and driven in a reciprocating motion by a system of levers in a crank-and-conrod mechanism 9. Under each barrel 5 and 6 can be installed with the pallet 10. At the rear of the frame 3 is installed a drum 11, consisting of a series of steel discs mounted on a common axis. Above it is mounted a milling drum 12 and a pitched tray 13, and a teyush, an opportunity to rise and fall, as well as a wedge-shaped puller (not shown in the drawing). At the top of the frame of the frame № 110458

A water tank 14 has been identified that is connected to an irrigation mechanism with hoses having a device similar to those of known transplanting machines.

The working bodies are actuated from the engine via the shaft 15. From here, the rotation is transmitted through chain and bevel gears to the drums 5, 6 vi 11. Through the chain and belt drives, the milling drum 12 is rotated. From the drums through a cylindrical gear, the curvature rotates and from them with the help of connecting rods swing the frame with a system of knives.

A selection of seedlings planted in a square-nested way from a greenhouse is carried out as follows.

The steering gears reels 5, 6 -l 11 are lowered into the working position. The elevator 4 is also folded back into working position, and the tray 13 is raised. The transfer to the drum 12 and to the mechanisms of the knives is turned off - When the mashina moves along the greenhouse, the seedlings are spread out using a lift 4. The 5 m 6 drums, immersed in the ground, rotate, cut out with discs and wedge the seedlings between them with pills In one turn of the reels 5 to 6, they are filled with ribbons of soil with a length equal to the length of the circumference of the drums and a width each equal to the distance between the discs (the size of the future earth cube with seedlings). At the same time, the drum 11, slamming its discs into the soil, is filled with it. After the reels 5, 6, and 11 are filled, they rise, the rotational transmission to them stops, and the machine moves to the pick point, transporting the ground and seedlings.

When picking up a seedling, one of the drums 5 or 6 is lowered into the ground or the greenhouse and a tray 10 is installed under it. After that, one of the drums is set to rotate periodically, and the knives 8 go deep into the slots 7 and cut the ground cubes with seedlings from the tapes. Then the knives push the cubes out of the spaces between the discs onto the pallet 10, and from there onto the ground and move to deepen into the next row of slots 7. As the drum 11 rotates, the wedge-shaped puller pushes the earth out of the drum grooves, which is loosened by the milling drum 12 and rolls on tray 13, falls asleep space between the cubes with seedlings installed on the ground. Simultaneously with the picking, water is watered on plants.

After releasing the drum b from the seedlings, the filled drum 5 is put into operation and the machine returns to the greenhouse to fill the seedlings and the ground.

Subject invention

A machine for sampling and picking up seedlings, consisting of a self-propelled frame, a water-jet installation and a milling drum for filling the soil with a space between the cubes with seedlings, which, in order to fully mechanize the selection and picking of seedlings, its selective-picking apparatus is made two consecutive disk knife drums with radial slits on the disks, which include knives mounted on a common frame, reciprocating from the crank mechanism.
