Description

TECHNICAL FIELD

[0001] The utility model relates to disc harrow technical field, concretely relates to a medium heavy disc harrow. BACKGROUND

[0002] Disc harrow is the traditional ploughing implement in agricultural production, and is one of the necessary implements for farmers and Chinese martial arts appliances, which is evolved from the implement. Disc harrow is the working component according to the principle of harrowing work, the harrow blade edge plane is perpendicular to the ground and has an adjustable angle with the machine set advancing direction. When working, the harrow blade rolls forward under the action of tractor traction and soil reaction force, the harrow blade edge cuts into the soil, cuts off the grass roots and crop residues, and makes the soil rise to a certain height along the harrow blade concave surface and then turn over and fall. When working, the fertilizer, pesticide and the like on the ground surface can be mixed with the surface soil, and it is commonly used for the shallow ploughing, stubble cleaning after crop harvesting, early spring soil conservation and soil crushing after ploughing, and can also be used for covering seed after airplane seeding. According to the configuration form of the harrow group, it can be divided into single column type, double column opposed type and offset type.

[0003] When the soil is too wet, the soil is easy to adhere to the harrow blade, causing the phenomenon of harrow blade blockage, therefore, in Chinese patent no. CN114557153A, a kind of agricultural machinery disc harrow for conveniently cleaning mud adhered to concave harrow blade is provided, which is connected with agricultural machinery by installing support, and the device is moved by agricultural machinery, when working, the disc harrow rotates and ploughs the land, the disc harrow drives the installation rod to rotate, drives the horizontal rod to rotate, the horizontal rod drives the first bevel gear to rotate, and then drives the vertical rod to rotate through the second bevel gear meshing with the first bevel gear, the vertical rod drives the scraper to rotate through the connecting rod, the scraper rotates to remove the mud adhered to the concave surface of the disc harrow, thereby realizing the effect of conveniently cleaning the mud adhered to the concave harrow blade of the disc harrow.

[0004] Since the device itself needs to drive multiple linkage mechanisms to rotate the scraper for cleaning by the disc harrow, the linkage mode is too complex, and multiple linkage mechanisms are exposed, which causes grass or silt to adhere to the gear during ploughing, resulting in blockage, so that the cleaning mechanism loses linkage and cannot clean the concave surface of the disc harrow. UTILITY MODEL CONTENTS

[0005] The utility model provides a kind of medium heavy disc harrow, which is integrated with scraper and harrow body, so that the scraper is flexibly attached to the concave surface of the disc harrow, and in the process of ploughing by agricultural machinery, the disc harrow is driven to rotate, which can remove silt from the concave surface of the stationary scraper, and the traditional bevel gear and other complex linkage components are discarded, so that the cleaning process is not blocked by grass, thereby solving the problems raised in the above background technology, i.e.

[0006] The linkage mechanism of the scraper in the prior art is too complex and exposed, which causes the problem that weeds or silt is easily attached to the gear during the plowing process, resulting in blockage and loss of linkage of the cleaning mechanism.

[0007] To achieve the above-mentioned purpose, the disc harrow device comprises a farm machine body, the farm machine body comprises a frame, and a plowing mechanism is arranged below the frame;

[0008] The plowing mechanism comprises a front harrow body area and a rear harrow body area;

[0009] The front harrow body area and the rear harrow body area are provided with scrapers on one side, which are used for cleaning the silt attached to the machine body;

[0010] The front harrow body area and the rear harrow body area are asymmetrically arc-shaped, and the arc shapes of the two areas are opposite to each other.

[0011] In the above technical solution, the scraper is made of flexible silica gel material, and a plurality of scrapers are respectively attached to the concave surfaces of the disc harrow bodies of the front harrow body area and the rear harrow body area. After the device is connected to the farm machine, the disc harrow body rotates, and when the disc harrow body rotates during plowing, it is easy to attach to the concave surface of the disc harrow body in the presence of high humidity soil. At this time, the scraper attached to the concave surface is in a fixed and stationary state. Through the continuous rotation of the disc harrow body, the scraper contact surface continuously removes the silt from the concave surface of the disc harrow body, keeping the concave surface clean.

[0012] On this basis, the rear harrow body area comprises a harrow body frame, the harrow body frame is fixedly connected with the frame, a plurality of nesting frames are fixedly installed on the outer surface of the harrow body frame, an inclined plate is fixedly connected to the bottom of the nesting frame, and the scraper is fixed with the inclined plate through bolts. The inclined plate is used to tilt the angle of the inclined plate and the disc harrow body. The inclined plate can be rotated to a suitable angle through the shaft, and is fixed after adjustment. The scraper is forced to contact the disc harrow body for cleaning work. In addition, the bolt fixing mode of the inclined plate and the scraper allows the scraper to be directly removed and replaced after long-term use and wear, so that the installation and removal of the cleaning mechanism is simple and the cost is reduced.

[0013] In another technical solution, a rotating shaft is arranged below the harrow body frame, the rotating shaft is rotatably connected to the frame near the two end faces, the center of the disc harrow body is rotatably connected to the rotating shaft, and an auxiliary rotating device is arranged between the rotating shaft and the plurality of disc harrow bodies. The auxiliary rotating device is used to drive the rotating shaft to rotate. When the device is not in use, the farm machine and the entire device are on flat ground. Because of the previous use, the disc harrow body circulates plowing, and there is always a part that has not been cleaned. At this time, the tire of the farm machine body itself is higher than the plowing mechanism on the flat ground, so that the front and rear areas of the harrow body are suspended. At this time, the auxiliary rotating device is opened, the harrow body is rotated, and the silt remaining on the concave surface can be removed by the centrifugal force of the disc harrow body and the scraper.

[0014] Compared with the prior art, the utility model has the beneficial effects of

[0015] Through the integration of the scraper and the rake body, the scraper is flexibly attached to the concave surface of the disc harrow body, in the process of the agricultural machine plowing, the disc harrow body is driven to rotate, so that the static scraper can scrape the silt on the concave surface, and the traditional bevel gear and other complex linkage components are abandoned, so that the blockage cleaning process caused by the blockage of weeds is avoided, in addition, on the flat ground, the disc harrow body in the air can also be rotated through the auxiliary rotating device, and the silt remaining on the concave surface of the disc harrow body is completely removed by the centrifugal force and the scraper.
