Description

Mounted cultivators (for example, a mountain self-propelled chassis) designed for processing tea plantations or other crops planted on mountain slopes are known. In these cultivators, the individual sections carrying the working members are articulated to the frame and allow the possibility of rotation in the transverse plane to adapt the sections to the slope of the ground.

Since the turning point of the section in such a construction is in its upper part, the lower ends of the working bodies, turning with the section, with one side move away from the base of the tea bush, and with the other side approach in the same space between the other tea bush. With such an approximation, the root system of one bush can be damaged, while the other has insufficient soil loosening.

In order to lower the turning point of the section and preserve the same distance between the extreme working bodies of the section and the plants to be treated, it is proposed ;: to install on the cultivator frame transverse arcuate guides with their center of curvature located below. The frame of the section, rolling over with these guides, will occupy the correct position with respect to the plants; moreover, in order to achieve automatic rotation of the section, its frame rests on the support wheels or polos and interlocks with a hydraulic mechanism turning the section to the desired angle.

Fig. 1 shows the position of the cultivator section on the slope among the tea bushes when it is rotated around a point located at the top; Fig 2 shows the position of the cultivator section among the tea bushes when it is rotated around a point located in the lower section section; in fig. 3 is a diagram of the proposed cultivator device.

FIG. 1 shows the location of the section / cultivator when the hinge 2 of its rotation is located in the upper part.

The driving wheel 3 of the self-propelled chassis is positioned vertically at the same distance from the plants to be treated. In this case, in order to give the workers of the section the organs the same depth of turn (indicated by the letter a, it turns on the hinge 2 to the left side. At the same time, the leftmost working members approach the root system of the left

a shrub for an excessively small amount of Cj and may newly hurt the roots, and on the other hand, at the right hive, retreat by the amount of Cg without cultivating the soil at the shrub.

FIG. The 2 running wheel 3 of the self-propelled chassis or cultivator frame is still directed vertically and runs at the same distance from the bushes to be processed. To give the section an inclination that is the same as the inclination of the slope, the section / is turned to the right around point 4 located in the reference plane of the working members. In this case, the end working bodies will be at the same distance C from both bushes and go at the same depth. The proposed cultivator for work on slopes consists of a fixed frame 5 (Fig. 3), carrying arcuate guides 6 and sections 7 with working bodies 8 ; The rollers of the section can roll along the guides 6, the outlined radius from point 4, which is located in the reference plane of the working parts of the cultivator.

On the pedestrian frame of the cultivator, a hydraulic nilder 9 is mounted, which is connected by a shaft 10 and a spool valve 11 to the section 7 of the cultivator by means of a lever 12.

In the system of the cylinder and distributor // pipeline receives oil from the hydraulic pump 13.

A fork 14 is pivotally mounted on the sliding frame, at the end of which are support wheels or polozki 15. Fork the probe lever 12 is pivotally connected to the valve of the distributor.

During operation in the flat area, the spool valve and the hydraulic cylinder are in the neutral position and the oil in the system has a free bypass to the oil tank.

When operating on a slope, a fork 14 with support wheels for a copier, a terrain relief, rotates around point 16 and through the lever 12 moves the valve to the corresponding position (depending on the direction of the slope) and the oil is pumped through the valve into this or that cavity of the hydraulic cylinder 9, affecting it pore

Through the piston rod 10, this pressure is transmitted to the frame of section 7, and it begins to rotate around point 4, rolling along guide 6; at the same time, the working bodies of the section occupy a position parallel to the slope. When this position is reached, the valve spool will take up a neutral position, since the distributor is fixed on the movable frame of the section and follows its turn. The flow of oil into the hydraulic cylinder 9 will stop and the cultivator section will be fixed in this position.

In this case, the extreme working bodies of the section will occupy the same position with respect to the bushes being processed, shown in FIG. 2

Subject invention

Claims (2)

1. A cultivator for working on slopes, sections of which carrying working members are suspended from the frame with the possibility of turning in the transverse plane to adapt the working bodies to the slope of the ground, characterized in that, in order to lower the turning point of the section and thereby maintain the same distance extreme working bodies from the treated plants; transverse arcuate guides are installed on the cultivator frame. 2. Cultivator according to claim 1, from l and h and with the fact that, in order to achieve automatic rotation of the section, its frame is carried by support wheels or poloks interlocked with the valve of the hydraulic mechanism distributor, which turns the section to the required angle, sufficient for positioning the working bodies of the section parallel to the soil surface. /ABOUT / J - -Fig. 3
