Description

The invention relates to agricultural machinery, in particular to combined soil cultivating implements equipped with a drive.

The purpose of the invention is to increase productivity.

Figure 1 shows a General view of the cultivator; figure 2 is a section aa in figure 1.

The motor-cultivator contains a frame 1 with an engine 2 mounted on it, which, through a transmission 3 through an asterisk 4, mounted on a hollow shaft 5, is connected with a milling working body b. The latter is mounted on a shaft 5 mounted horizontally on the frame 1 for rotation. In the cavity of the shaft 5, coaxially with respect to its horizontal axis, a shaft 7 of the tool 8 is mounted to rotate relative to it to increase the adhesion of the milling tool 6 to the soil. The device 8 is made in the form of a disk with tillers. An asterisk 9 is fixed on the shaft 7, by means of which the device 8 is connected to the engine 2. On the frame 1, behind the milling working element 6, a passive tillage working body is placed.

Motocultivator works as follows.

After starting the engine 2, the torque from it through the transmission 3 and the sprocket 4 is transmitted to the shaft 5 and the milling working element 6, which, while rotating, loosens the soil. At the same time, through the sprocket 9, the torque from the engine 2 is transmitted to the shaft 7. The latter, rotating in the hollow shaft 5, transmits the torque to the device 8 to increase the adhesion of the milling working member 6 to the soil. With its tipping devices, the device 8 is pressed into the soil surface, increasing the pulling force, moves the frame 1 relative to the soil together with the passive tillage organ. Gear ratio between engine 2 and milling worker

body 6 on the one hand and between engine 2 and tool 8 on the other hand is selected so that the peripheral speed of the tool 8, and, accordingly, the linear speed of the cultivator is 3-5% higher than the peripheral speed of the milling tool 6.

Motocultivator allows you to increase productivity when processing soil

due to the mismatch of the speeds of the running and loosening elements, to ensure a stable speed of the tool, increase durability, improve the quality of soil cultivation.

Claims (1)

Claims A motocultivator containing an engine mounted on the frame, connected to the engine by means of a transmission, a milling working element in the form of a shaft with a horizontal axis of rotation and working elements fixed on it, a working element of passive action located behind the milling working element, and an organ installed coaxially with the milling device rotatable device for increasing the adhesion of the latter to the soil, having a hub with tillers, characterized in that, in order to increase productivity In the process of soil cultivation, the shaft of the milling working body is hollow, and the hub of the device for increasing the adhesion of the milling working body to the soil is made in the form of a disk mounted on an additional shaft located in the cavity of the milling working body shaft, which has an independent drive from the motor-cultivator of the device.
