Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment, specifically to an anti-clogging bracket for a grid plowshare assembly. Background Technology

[0002] A slat plow is a plowshare designed with slats to reduce the contact area between the plowshare and the soil, thereby reducing the chance of the plowshare sticking to the soil and achieving the goal of reducing the resistance of turning the soil.

[0003] The existing anti-clogging bracket of the grid plow consists of multiple steel bars. One end of each steel bar is installed on the plow body bracket, and the other ends of the steel bars are interconnected by a transverse brace to form a hollow bracket between the steel bars, which is used to prevent the plow from being blocked by weeds, soil and other debris during operation.

[0004] However, anti-blocking brackets are usually installed on the plow body bracket with bolts. Since the plow head will vibrate during operation, it is necessary to install an anti-loosening fixing component to prevent the anti-blocking bracket from loosening and falling off due to impact and vibration. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-blocking bracket for a grid plow head assembly, in order to solve the problem mentioned in the background art that the anti-blocking bracket is usually installed on the plow body bracket with bolts. Since the plow head will vibrate during operation, it is necessary to set up an anti-loosening fixing component to prevent the anti-blocking bracket from loosening and falling off due to impact and vibration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-blocking bracket for a bar plowshare assembly, comprising: a mounting frame and a plowshare bracket, a fixing device being provided on the outer side of the plowshare bracket, a bar plowshare body being fixedly mounted on the side surface of the plowshare bracket, an anti-blocking bracket body being provided on the side surface of the bar plowshare body, and the fixing device comprising: a stud, a first inner cavity and a second inner cavity being provided on the inner surface of the stud, a round rod being provided on the inner surface of the first inner cavity, and a spring being provided on the inner surface of the second inner cavity;

[0007] The clearance groove is formed on the outer surface of the stud. A pressure plate is fixedly installed at the bottom end of the round rod. An installation groove is formed on the outer surface of the round rod near the pressure plate. Two symmetrically arranged limit brackets are elastically connected to the inner surface of the installation groove.

[0008] Preferably, the grid plow head body is fixedly installed on the bottom side surface of the mounting frame via a plow body bracket, and the anti-blocking bracket body and the plow body bracket are fixedly installed via a fixing device.

[0009] Preferably, the round rod slides within the first inner cavity via an elastic connection between a pressure plate and a spring.

[0010] Preferably, the inner surface of the limiting bracket is provided with a torsion spring, and the limiting bracket is elastically connected to the mounting groove through the torsion spring.

[0011] Preferably, the outer surface of the stud is provided with internal threads, and a nut is connected to it through the internal threads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model proposes an anti-blocking bracket for a grid plowshare assembly;

[0014] By setting up a fixing device, when installing the anti-blocking bracket body, pressing the round rod in the first inner cavity drives the pressure plate to compress the spring in the second inner cavity, which in turn drives the limiting bracket in the mounting groove to retract into the clearance groove through the torsion spring. Then, the stud is inserted through the plow body bracket, and the pressed round rod is released. The limiting bracket is rebounded by the spring and unfolds from the clearance groove. The unfolded limiting bracket is close to the side wall of the anti-blocking bracket body. Then, the anti-blocking bracket body is fixed to the side surface of the plow body bracket by the threaded engagement of the nut and the stud. This effectively prevents the anti-blocking bracket body from loosening under harsh working conditions such as vibration and impact, avoids safety accidents caused by connection failure, ensures a stable connection of the anti-blocking bracket, maintains the normal working condition of the plow head assembly, and prevents equipment damage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-blocking bracket for a grid plowshare assembly;

[0022] Example 1:

[0023] To prevent loosening during installation of the anti-clogging bracket body 4, a fixing device 5 is provided on the outer side of the plow body bracket 2. A grid plow head body 3 is fixedly installed on the side surface of the plow body bracket 2, and the anti-clogging bracket body 4 is provided on the side surface of the grid plow head body 3. The fixing device 5 includes: a stud 501, with a first inner cavity 502 and a second inner cavity 504 on its inner surface; a round rod 503 on the inner surface of the first inner cavity 502; a spring 505 on the inner surface of the second inner cavity 504; and a clearance groove 510 on the outer surface of the stud 501. A pressure plate 506 is fixedly installed at the bottom end of the round rod 503, and an installation groove 507 is provided at one end of the outer surface of the round rod 503 near the pressure plate 506. Two symmetrically arranged limiting brackets 508 are elastically connected to the inner surface of the installation groove 507. The grid plow head body 3 is fixedly installed on the bottom side surface of the mounting bracket 1 via the plow body bracket 2. The anti-clogging bracket body 4 and... The plow body bracket 2 is fixedly installed by the fixing device 5. The round rod 503 slides in the first inner cavity 502 through the elastic connection between the pressure plate 506 and the spring 505. The inner surface of the limiting bracket 508 is provided with a torsion spring 509. The limiting bracket 508 is elastically connected to the mounting groove 507 through the torsion spring 509. When installing the anti-blocking bracket body 4, pressing the round rod 503 in the first inner cavity 502 drives the pressure plate 506 to compress the spring 505 in the second inner cavity 504. This causes the limiting bracket 508 in the mounting groove 507 to retract into the clearance groove 510 via the torsion spring 509. Then, the stud 501 is inserted through the plow body bracket 2, and the pressed round rod 503 is released. The limiting bracket 508 is rebounded from the clearance groove 510 by the spring 505. The extended limiting bracket 508 is in close contact with the side wall of the anti-blocking bracket body 4. Then, the anti-blocking bracket body 4 is fixed to the side surface of the plow body bracket 2 by the threaded engagement of the nut 7 and the stud 501.

[0024] Working principle: In actual use, pressing the round rod 503 in the first inner cavity 502 drives the pressure plate 506 to compress the spring 505 in the second inner cavity 504, which in turn drives the limiting bracket 508 in the mounting groove 507 to retract into the clearance groove 510 through the torsion spring 509. Then, the stud 501 is inserted through the plow body bracket 2, and the pressed round rod 503 is released. The limiting bracket 508 is rebounded by the spring 505 and unfolds from the clearance groove 510. The unfolded limiting bracket 508 is close to the side wall of the anti-blocking bracket body 4. Then, the anti-blocking bracket body 4 is fixed to the side surface of the plow body bracket 2 through the threaded engagement of the nut 7 and the stud 501. This effectively prevents the anti-blocking bracket body 4 from loosening under harsh working conditions such as vibration and impact, avoids safety accidents caused by connection failure, ensures a stable connection of the anti-blocking bracket, maintains the normal working condition of the plow head assembly, and prevents equipment damage.
