Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery tool installation technology, and specifically discloses a quick-release agricultural machinery tool fixing device. Background Technology

[0002] Agricultural machinery cutting tools are cutting tools used on agricultural machinery to complete various tasks. Their performance and quality directly affect the efficiency, quality, and cost of agricultural production. With the rapid development of agricultural mechanization, the types of agricultural machinery cutting tools are becoming increasingly diverse, and their functions are becoming more varied. From the perspective of function and use, agricultural machinery cutting tools can be divided into tillage tools, land preparation tools, seeding tools, plant protection tools, and harvesting tools, etc.

[0003] Traditional agricultural machinery tool fixing devices use multiple bolts for fastening. When replacing or repairing the tools, tools are needed to loosen each bolt one by one, which is time-consuming and greatly reduces work efficiency. Therefore, a quick-release agricultural machinery tool fixing device is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a quick-release agricultural machinery tool fixing device. Through the cooperation of a spring-preloaded sliding plate mechanism and an arc-shaped positioning column, the tool can be installed and removed with a "one-click" action, which shortens the operation time and greatly improves the efficiency of tool installation and removal.

[0005] This utility model is implemented as follows: a quick-release agricultural machinery knife fixing device includes a mounting frame, the bottom end of which is provided with a knife mounting groove, and a knife body is provided in the knife mounting groove. The knife body is detachably connected to the knife mounting groove through a disassembly assembly.

[0006] The assembly and disassembly assembly includes an assembly block disposed inside the tool mounting slot. The assembly block has a cavity inside, and two sliding plates are slidably connected inside the cavity. A spring is installed between the two sliding plates. A connecting rod is fixedly connected to the opposite side of each of the two sliding plates. A positioning frame extending to the outside of the assembly block is fixedly connected to the opposite side of each of the two connecting rods.

[0007] The assembly and disassembly assembly also includes positioning posts fixedly connected to the left and right sides of the inner wall of the tool mounting slot, and both positioning posts are adapted to the positioning frame.

[0008] As a preferred embodiment of the quick-release agricultural machinery tool fixing device of this utility model, the outer walls of the two positioning frames are fixedly connected with fixing columns, the outer walls of the two fixing columns are fixedly connected with sliding rods on opposite sides, and the outer walls of the opposite sides of the two sliding rods are slidably connected with sliding cylinders located in front of the mounting block. The sliding cylinders and the two sliding rods are connected by locking bolts.

[0009] As a preferred embodiment of the quick-release agricultural machinery tool fixing device of this utility model, the bottom end of the mounting block is fixedly connected to a mounting plate, the upper end face of the tool body is inserted into the mounting plate, and is connected to the mounting plate by locking bolts.

[0010] As a preferred embodiment of the quick-release agricultural machinery tool fixing device of this utility model, the end of the positioning column near the positioning frame has an arc-shaped structure.

[0011] As a preferred embodiment of the quick-release agricultural machinery tool fixing device of this utility model, the mounting block has through holes communicating with the cavity on both the left and right sides.

[0012] As a preferred embodiment of the quick-release agricultural machinery tool fixing device of this utility model, the outer wall of the slide cylinder is provided with an anti-slip sleeve.

[0013] The beneficial effects of this utility model are:

[0014] By pushing the mounting block into the tool mounting slot, the arc-shaped end of the positioning post presses the positioning frame into the cavity inside the mounting block, compressing the spring. When the mounting block is fully inserted into the tool mounting slot, the positioning frame, under the spring's rebound force, engages with the outside of the positioning post, achieving locking. For disassembly, the two positioning frames move closer together, causing them to separate from the positioning post, and the mounting block is pulled outwards from the tool mounting slot, allowing for quick tool removal. The spring-loaded sliding plate mechanism, in conjunction with the arc-shaped positioning post, enables "one-click" tool assembly and disassembly; only one locking bolt needs to be loosened, significantly reducing operation time and improving tool assembly and disassembly efficiency.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] Please see Figure 1-3 A quick-release agricultural machinery knife fixing device includes a mounting frame 1. The bottom end of the mounting frame 1 is provided with a knife mounting groove 101. A knife body 201 is provided in the knife mounting groove 101. The knife body 201 is detachably connected to the knife mounting groove 101 through a disassembly assembly.

[0023] The assembly and disassembly assembly includes a mounting block 3 disposed inside the tool mounting slot 101. The mounting block 3 has a cavity inside, and two sliding plates 301 are slidably connected inside the cavity. A spring 302 is installed between the two sliding plates 301. A connecting rod 303 is fixedly connected to the opposite side of each of the two sliding plates 301. A positioning frame 304 extending to the outside of the mounting block 3 is fixedly connected to the opposite side of each of the two connecting rods 303.

[0024] The assembly and disassembly assembly also includes positioning posts 102 that are fixedly connected to the left and right sides of the inner wall of the tool mounting slot 101. Both positioning posts 102 are adapted to the positioning frame 304.

[0025] In this embodiment: During installation, the mounting block 3 is pushed into the tool mounting groove 101. The arc-shaped end of the positioning post 102 first contacts the positioning frame 304, squeezing the positioning frame 304 into the cavity inside the mounting block 3, which in turn drives the connecting rod 303 and the sliding plate 301 to compress the spring 302. When the mounting block 3 is fully inserted into the tool mounting groove 101, the positioning frame 304 is locked into the outside of the positioning post 102 under the rebound force of the spring 302. During disassembly, the two positioning frames 304 move towards each other, causing the positioning frame 304 to separate from the positioning post 102, and the mounting block 3 is pulled out of the tool mounting groove 101, allowing the tool to be quickly removed. The spring-preloaded sliding plate 301 mechanism cooperates with the arc-shaped positioning post 102 to achieve "one-click" disassembly and assembly of the tool, shortening the operation time and greatly improving the efficiency of tool disassembly and assembly.

[0026] As a technical optimization of this utility model, the outer walls of the two positioning frames 304 are fixedly connected with fixed columns 4, and the outer walls of the two fixed columns 4 are fixedly connected with sliding rods 402 on opposite sides. The outer walls of the opposite sides of the two sliding rods 402 are slidably connected with sliding cylinders 401 located in front of the mounting block 3. The sliding cylinders 401 and the two sliding rods 402 are connected by locking bolts.

[0027] In this embodiment: while the automatic snap-fit ​​is completed, the two slide rods 402 slide on the inner wall of the slide cylinder 401. Since the diameter of the right slide rod 402 is larger than that of the left slide rod 402, the left slide rod 402 can be slidably inserted into the right slide rod 402. Then, the slide cylinder 401 and the two slide rods 402 can be fixed by the locking bolt, so as to achieve stable installation of the tool body 1.

[0028] As a technical optimization of this utility model, the bottom end of the mounting block 3 is fixedly connected to the mounting plate 2, and the upper end face of the tool body 201 is inserted into the mounting plate 2 and connected to the mounting plate 2 by locking bolts.

[0029] In this embodiment: the tool body 201 is inserted into the matching groove at the bottom of the mounting plate 2 and then fixed by the locking bolt.

[0030] As a technical optimization of this utility model, the end of the positioning post 102 near the positioning frame 304 has an arc-shaped structure.

[0031] In this embodiment, the positioning frame 304 is guided to shrink smoothly by the arc surface, reducing installation resistance.

[0032] As a technical optimization of this utility model, the mounting block 3 has through holes on both the left and right sides that communicate with the cavity.

[0033] In this embodiment, the through hole facilitates the smooth sliding of the connecting rod 303 within the cavity.

[0034] As a technical optimization of this utility model, the outer wall of the slide 401 is provided with an anti-slip sleeve.

[0035] In this embodiment, the anti-slip sleeve increases the friction between the operator's hand and the slide 401, making it less likely for the operator to slip when holding the slide 401.

[0036] The working principle and usage process of this utility model are as follows: During installation, the mounting block 3 is pushed into the tool mounting groove 101. The arc-shaped end of the positioning post 102 first contacts the positioning frame 304, squeezing the positioning frame 304 into the cavity inside the mounting block 3. At the same time, the two sliding rods 402 move in opposite directions inside the sliding cylinder 401. The left sliding rod 402 slides and inserts into the right sliding rod 402, and drives the connecting rod 303 and the sliding plate 301 to compress the spring 302. When the mounting block 3 is fully inserted into the tool mounting groove 101, the positioning frame 304 is locked into the outside of the positioning post 102 under the action of the spring 302's rebound force. At the same time, the left sliding rod 402 and the right sliding rod 402 move away from each other, but the left sliding rod 402 will not completely disengage from the right sliding rod 402 (e.g., Figure 1 (As shown), then lock the slide cylinder 401 and the two slide rods 402 with the locking bolts. To disassemble, loosen the locking bolts, then manually push the two fixing posts 4 closer together, causing the two positioning frames 304 to move towards each other, causing the positioning frames 304 to separate from the positioning posts 102, and pull the mounting block 3 outwards from the tool mounting slot 101, so that the tool can be quickly removed.

[0037] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
