Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery chains, in particular to an anti-sputtering agricultural machinery chain. Background Art

[0002] Agricultural machinery chains are metal links or rings, mostly used for mechanical transmission and traction. Among similar products, the chain product series are divided according to the basic structure of the chain, that is, according to the shape of the components, the parts and positions that mesh with the chain, and the size ratio between the parts. There are many types of chains, but their basic structures are only the following, and the others are all deformations of these types. We can see from the above chain structures that most chains are composed of chain plates, chain pins, bushings and other components.

[0003] The existing agricultural machinery chains are usually exposed on the outside of the agricultural machinery, and cannot protect the chains from being corroded by stains such as mud. Long-term erosion by mud will cause the chains to rust or even be damaged. When the existing agricultural machinery chains are damaged, professional tools are required to repair them, and the damaged parts cannot be quickly replaced by oneself, which is rather troublesome. The existing agricultural machinery chains cannot automatically clean the chains in real time, and manual cleaning is required, which is rather troublesome. Therefore, an anti-splashing agricultural machinery chain is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide an anti-splashing agricultural machinery chain to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A splash-proof agricultural machinery chain comprises a shell, a chain plate, a chain pin and a shaft sleeve, wherein a fixing piece is fixedly connected to the outer side of the shell, a rubber pad is fixedly connected to one side edge of the shell, a first limiting hole is provided on the outer side of the shell, a gear plate is rotatably connected to the inside of the first limiting hole, a chain consisting of a chain plate, a chain pin, a second limiting hole, a third limiting hole and a shaft sleeve is meshed and connected to the outer side of the gear plate, a fixing plate is fixedly connected to the inside of the shaft sleeve, a spring is fixedly connected to one end of the fixing plate, a button is fixedly connected to the top of the spring, a first limiting block is fixedly connected to the outer side of the button, a second limiting block located below the first limiting block is fixedly connected to the outer side of the button, a second limiting groove is provided on the outer side of the shaft sleeve, a connecting rod located outside the spring is fixedly connected to the top of the fixing plate, a connecting block is fixedly connected to one side of the connecting rod, a block on one side of the connecting rod away from the connecting block, a first limiting groove is provided inside the third limiting hole, a nut located above the chain plate is spirally connected to the outer side of the shaft sleeve, and a cleaning port is provided at the bottom end of the shell.

[0007] Preferably, a cleaning brush is fixedly connected to the inner side of the shell, and there are four cleaning brushes, two of which form a group and are symmetrically arranged on both sides of the chain plate and the chain pin.

[0008] Preferably, a connecting rod, a clamping block and a connecting block are slidably connected inside the second limiting groove.

[0009] Preferably, the button and the spring form a group, there are two groups in total, and they are symmetrically arranged at both ends of the fixing plate.

[0010] Preferably, the connecting block is in close contact with the second limiting block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the housing, the fixing member, the first limiting hole, the rubber pad and other components are provided, and the housing is clamped on the outer side of the gear plate through the first limiting hole to play a limiting role. Then, the housing and the agricultural machine are firmly fixed together by bolts passing through the fixing member, and the chain is protected from mud splashing by the housing, thereby solving the problem that the existing agricultural machinery chain is usually exposed to the outside of the agricultural machinery, and the chain cannot be protected from being corroded by mud and other stains, and the long-term mud erosion will cause the chain to rust or even be damaged;

[0013] 2. In the utility model, by setting the chain plate, chain pin, shaft sleeve, second limit hole, button, first limit block, nut, fixing plate, spring, second limit block, connecting rod, clamping block, first limit groove, connecting block, third limit hole and second limit groove and other components, firstly unscrew the nut to loosen the shaft sleeve and the chain plate, then press the button, and drive the second limit block to move downward through the button to separate the second limit block from the connecting block. Since the connecting block lacks support, it restores the vertical state under the toughness of the connecting rod. When the connecting rod rebounds, it drives the clamping block to disengage from the first limit groove, and then the shaft sleeve can be easily removed from the second limit hole and the third limit groove. The second limiting block and the connecting block can be taken out from the limiting hole to separate the chain plate and the chain pin for easy replacement. After replacing a broken chain section, the second limiting hole of the chain plate and the third limiting hole of the chain pin are overlapped, and the buttons at both ends are pressed to insert the shaft sleeve. After being engaged in place, the button pops out under the rebound action of the spring, and the second limiting block and the connecting block are driven by the button to re-contact, and the card block is re-engaged in the first limiting groove to complete the initial fixation of the chain plate and the chain pin. Finally, the nut is re-tightened to complete the replacement, thereby solving the problem that when the existing agricultural machinery chain is damaged, professional tools are needed to repair it, and the damaged part cannot be quickly replaced by oneself, which is more troublesome.

[0014] 3. In the utility model, by providing components such as a cleaning brush, a gear plate, a chain plate, a chain pin, a bushing and a cleaning port, when the agricultural machinery is in operation, the gear plate drives the chain to rotate. Through the continuous rotation of the chain and the continuous contact of the cleaning brush, the effect of automatically cleaning the chain surface is formed, and the cleaned dust will be naturally discharged through the cleaning port at the bottom of the shell, thereby solving the problem that the existing agricultural machinery chain cannot automatically clean the chain in real time and requires manual cleaning, which is troublesome.

[0026] A cleaning brush 4 is fixedly connected to the inner side of the outer shell 1. There are four cleaning brushes 4, and each two form a group, which are symmetrically arranged on both sides of the chain plate 7 and the chain pin 8. The inside of the second limit groove 22 is slidably connected with a connecting rod 17, a card block 18 and a connecting block 20. The button 11 and the spring 15 form a group, and there are two groups in total, which are symmetrically arranged at both ends of the fixed plate 14 in the upper and lower directions. The connecting block 20 is in close contact with the second limit block 16.

[0027] Working process: when it is necessary to use an anti-splashing agricultural machinery chain, the housing 1 is engaged on the outer side of the gear plate 6 through the first limiting hole 5 to play a limiting role, and then the housing 1 is firmly fixed to the agricultural machinery through the bolt passing through the fixing piece 2, and the chain is protected by the housing 1 from sludge splashing.
