Description

Technical Field

[0001] The utility model relates to the field of agriculture, and particularly to a fixing device for agricultural operations. Background Technique

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. When plowing, a rotary tiller is needed to cut soil blocks. When the blades are used to cut soil blocks for a long time, the blades may rust. Therefore, it is necessary to quickly disassemble, install and fix the blades for easy maintenance.

[0003] After retrieval, in the prior art, the Chinese patent with the patent publication number CN220986511U discloses "a fixing device for agricultural operations", which relates to the field of agricultural technology and particularly to a fixing device for agricultural operations, including: a horizontal shaft, a blade fixing seat, a telescopic limit pin, a blade head and a blade body. The blade fixing seats are fixedly installed on the horizontal shaft at equal intervals. The telescopic limit pins are installed on both sides of the blade fixing seat. The blade head is inserted into the blade fixing seat. The blade body is fixedly installed on the side wall surface of the blade head. The blade fixing seat is fixed on the horizontal shaft by threaded connection. The limit pins are telescopically installed on both sides of the blade fixing seat. The blade handle is inserted into the center of the blade fixing seat. The blade is fixedly installed in the blade fixing seat by inserting the limit pins on both sides of the blade handle. During actual use and disassembly, the telescopic limit pins are pulled out from both sides of the blade fixing seat, and the blade can be disassembled from the blade fixing seat. The installation and disassembly are convenient and the fixing is firm, which is convenient for actual use. However, there are still the following defects: when disassembling and assembling the blade head, the telescopic spring is used to make the telescopic pin body move to disassemble and assemble the blade head. When the device rotates to cut soil blocks, the device will generate bumps, which will cause the telescopic spring to shake continuously, resulting in the blade head falling off, having a certain potential safety hazard.

[0004] Therefore, we make improvements on this and propose a fixing device for agricultural operations. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0030] Therefore, the following detailed description of the embodiments of the present utility model is not intended to limit the scope of the present utility model claimed, but merely represents some embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0031] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0032] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] As Figures 1-6 shown, this embodiment provides an agricultural operation fixing device, including a shaft body 1, a hub 2, and a cutter head 3. The hub 2 is bolted to both ends of the shaft body 1. The cutter head 3 is arranged on one side of the shaft body 1. An assembly and disassembly mechanism 4 for quickly replacing the cutter head 3 is arranged outside the shaft body 1, and a limiting component 5 is arranged inside the assembly and disassembly mechanism 4;

[0034] The assembly and disassembly mechanism 4 includes an installation groove 401, a tool handle 402, an installation tube 403, an arc groove 404, a limiting groove 405, a limiting rod 406, a spring 407, and a support plate 408. The installation groove 401 is opened on the outer wall of the shaft body 1. The tool handle 402 is welded to the side wall of the cutter head 3. The installation tube 403 is threadedly connected to the inside of the installation groove 401. The arc groove 404 is opened on the outer wall of the installation tube 403. The limiting groove 405 is opened on the side wall of the arc groove 404. The limiting rod 406 is welded to the side wall of the tool handle 402. The spring 407 is welded to the inner wall of the installation tube 403. The support plate 408 is welded to one end of the spring 407. The tool handle 402 is slidably connected to the installation tube 403. The limiting rod 406 is slidably connected to the arc groove 404 and the limiting groove 405. The elastic force of the spring 407 can fix the limiting rod 406 inside the limiting groove 405. When the device rotates, due to the centrifugal force, the limiting rod 406 will firmly abut against the inside of the limiting groove 405, thereby preventing the cutter head 3 from falling off and causing potential safety hazards.

[0035] As Figure 6As shown, as a preferred embodiment, on the basis of the above method, further, the limiting component 5 includes a round rod 501, a limiting plate 502 and a limiting tube 503. The round rod 501 is welded to the inner wall of the mounting tube 403, the limiting plate 502 is welded to one end of the round rod 501, and the limiting tube 503 is welded to the side wall of the support plate 408. One end of the round rod 501 extends into the limiting tube 503 and is slidably connected to the limiting tube 503. When the cutter head 3 is removed, due to the limiting effect of the round rod 501 and the limiting plate 502, it can prevent the spring 407 from being overstretched and damaged, and improves the service life of the spring 407.

[0036] As Figure 6 shown, as a preferred embodiment, on the basis of the above method, further, a mounting plate 6 is welded to the side wall of the mounting tube 403. A bolt 7 is threadedly connected inside the mounting plate 6. One end of the bolt 7 extends into the shaft body 1 and is threadedly connected to the shaft body 1. The number of bolts 7 is four and they are evenly distributed. By screwing the bolts 7 into the mounting plate 6 and the shaft body 1 in sequence, the anti-detachment effect of the mounting tube 403 can be significantly improved, and the safety of the device is enhanced.

[0037] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a rectangular groove 8 for facilitating the movement of the cutter head 3 is formed on the side wall of the cutter head 3. A cross bar 9 is welded to the inner wall of the rectangular groove 8. When the user moves the cutter head 3, by holding the cross bar 9, it is more convenient to apply a pushing force or a pulling force to the cutter head 3, improving the convenience.

[0038] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a hexagonal nut 10 for facilitating the rotation of the handle 402 by the user is welded to the outer wall of the handle 402. The hexagonal nut 10 is made of stainless steel. When the device is used up, more soil may accumulate in the arc-shaped groove 404 and the limiting groove 405, making it inconvenient to rotate the handle 402. By using an external wrench in cooperation with the hexagonal nut 10, it is more convenient to rotate the handle 402.

[0039] As Figure 1 shown, as a preferred embodiment, on the basis of the above method, further, an anti-rust layer 11 is provided on the outer wall of the cutter head 3. The anti-rust layer 11 is made of epoxy resin paint. The anti-rust layer 11 is used to prevent the cutter head 3 from rusting. When breaking soil clods, the soil clods contain moisture, and at this time, the anti-rust layer 11 can prevent the cutter head 3 from rusting and improves the service life of the cutter head 3.

[0040] As Figure 1As shown, as a preferred embodiment, on the basis of the above method, further, an extension block 12 for improving the grip of the shaft hub 2 is welded on the outer wall of the shaft hub 2. The number of extension blocks 12 is several and they are circumferentially distributed. When the shaft hub 2 moves on the ground, the extension block 12 can improve the grip of the shaft hub 2.

[0041] Specifically, when the agricultural machinery operation fixing device needs to repair and replace the cutter head 3: the user holds the cross bar 9 with his hand and then pushes the cutter head 3 and the tool handle 402 to move to one side with force. When the tool handle 402 moves, the limiting rod 406 on the outer wall of the tool handle 402 will disengage from the limiting groove 405. At this time, the user rotates the tool handle 402 to one side, or other personnel can rotate the hexagonal nut 10 with an external wrench to conveniently rotate the tool handle 402. After the tool handle 402 rotates, the limiting rod 406 enters the inside of the arc-shaped groove 404. At this time, the limiting rod 406 loses its limitation, and then due to the elastic force of the spring 407, the support plate 408 drives the tool handle 402 to move along the arc-shaped groove 404. Then the user can remove the cutter head 3 and then perform maintenance and replacement. When installing the cutter head 3, insert the tool handle 402 into the inside of the installation pipe 403, then make the limiting rod 406 enter the arc-shaped groove 404, then push the cutter head 3 to one side, so that the limiting rod 406 contacts one end of the arc-shaped groove 404, and then rotate the cutter head 3, so that the limiting rod 406 enters the inside of the limiting groove 405, thus completing the installation. When using this device to break soil clods, due to the action of centrifugal force, the outer wall of the limiting rod 406 will firmly abut against the inside of the limiting groove 405, thus avoiding the problem of potential safety hazards caused by the detachment of the cutter head 3.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
