Description

Technical Field

[0001] The utility model relates to the technical field of beaters, in particular to a beater connecting arm structure which is easy to assemble and disassemble. Background Art

[0002] In the agricultural field, traditional paddy field cultivation uses cattle or tractors with harrows to turn the soil and cultivate the land, then irrigate the farmland, and then carry out subsequent rice planting operations. The straw left over from the previous crop is generally left in the field. The traditional method is to burn the straw of the previous crop to facilitate subsequent farming and transplanting. With the increasing requirements for environmental protection and the promotion of the practice of straw into the field, straw can no longer be burned. The straw needs to be buried in the ground, and the field needs to be pulped and leveled later. In order to achieve the above purpose, before transplanting, the straw is generally rotary tilled, that is, the straw is broken up, and then the stubble is buried. The straw is buried underground and then leveled by pulping. The connecting arm can mainly connect the pulper with the drive vehicle.

[0003] When the existing beater connecting arm is in use, it is usually connected to the driving vehicle by a connecting rod, and then fixed by an elastic pin. After the beater is used, it is usually necessary to disassemble the beater and the driving vehicle, and tools are needed to open the pin. Since the connection strength needs to be ensured, the pin strength here is relatively high, and it is not convenient to open and disassemble it, so the beater and the driving vehicle cannot be disassembled quickly. For this reason, we propose a beater connecting arm structure that is easy to disassemble and assemble. Utility Model Content

[0004] In response to the above problems, the present invention provides a beater connecting arm structure that is easy to assemble and disassemble, which can solve the problems existing in the above background technology.

[0021] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figure 1-Figure 4 As shown, a beater connecting arm structure that is easy to disassemble and assemble includes a connecting arm body 1, a beater 2 is provided on the outer side of one end of the connecting arm body 1, a fixed sleeve 3 is provided on the surface of the other end of the connecting arm body 1, and a connecting limit mechanism 4 is provided on the surface of the connecting arm body 1 near the fixed sleeve 3. The connecting limit mechanism 4 includes a connecting sleeve block 6, and a movable pull rod 7 is movably connected to the inside of the connecting sleeve block 6. One end of the movable pull rod 7 is fixedly connected to a force-bearing mounting plate 8, and a force spring 9 is fixedly connected between one side of the force-bearing mounting plate 8 and one end of the inside of the connecting sleeve block 6. The other end of the movable pull rod 7 is fixedly connected to a connecting pull plate 10, and the other side of the force-bearing mounting plate 8 is fixedly connected to a reinforcing limit plug rod 11.

[0024] The working principle of the above technical solution is as follows:

[0025] During use, the end of the connecting arm body 1 can be fitted with the connecting arm of the external driving vehicle, and then the connector is inserted into the external connecting arm, the connecting arm body 1 and the fixed sleeve 3, and the connection limit can be quickly performed through the connection limit mechanism 4, and vice versa, it can also be quickly disassembled, so that the connecting pull plate 10 is pulled to drive the movable pull rod 7, the force mounting plate 8 and the reinforced limit plug rod 11 to move, causing compression to the force spring 9, so that the reinforced limit plug rod 11 can be pulled out from the inside of the movable plug mechanism 5, thereby quickly performing the disassembly operation.

[0026] In another embodiment, Figure 2 As shown, a movable plug-in mechanism 5 is movably connected between the connecting arm body 1 and the inner side of the fixed sleeve 3 .

[0027] When the connecting arm body 1 and the external connecting arm are fitted together, the movable plug-in mechanism 5 can be quickly and stably inserted into the connecting arm body 1 and the external connecting arm, and connected and matched with the connection limiting mechanism 4, thereby achieving a quick connection.

[0028] In another embodiment, Figure 4 As shown, the movable plug-in mechanism 5 includes a connecting limit rod 14, one end of the connecting limit rod 14 is fixedly connected to the movable connecting rod 12, the other end of the movable connecting rod 12 is fixedly connected to the connecting limit plate 13, and a fixed through groove 17 is opened on the outer side of the surface of the connecting limit rod 14.

[0029] The connection limit rod 14 can be quickly inserted between the connecting arm body 1 and the inside of the external connecting arm. At the same time, the external connecting arm can be stably located on the outside of the movable connecting rod 12. The connection limit rod 14 is connected and matched with the fixed through groove 17. The connection limit plate 13 can limit the position of the external connecting arm, which is easy to operate.

[0030] In another embodiment, Figure 4 As shown, a mounting groove 15 is provided on the outer side of the surface of the movable connecting rod 12 , and a movable ball 16 is movably provided on the inner side of the mounting groove 15 .

[0031] It is convenient to drive the external connecting arm to deflect during the operation of the vehicle, so that the external connecting arm can be stably deflected on the outside of the movable ball 16, and the operation is convenient.

[0032] In another embodiment, Figure 2 As shown, the outer surface of the connection limit rod 14 is slidably fitted with the inner side of the fixing sleeve 3 and the connecting arm body 1 .

[0033] The connection limiting rod 14 can be stably inserted between the connecting arm body 1, the fixing sleeve 3 and the interior of the external connecting arm to connect and avoid shaking.

[0034] In another embodiment, Figure 4 As shown, the inner side of the fixing groove 17 and the outer side of the surface of the reinforcing limiting rod 11 are in contact with each other.

[0035] This facilitates the end portion of the reinforcing limiting rod 11 to be stably inserted into the inner side of the fixing slot 17 , thereby performing connection restriction.

[0036] The working principle of the present invention: During use, pulling the connecting pull plate 10 drives the movable pull rod 7, the force-bearing mounting plate 8 and the reinforced limiting plug rod 11 to move, causing compression to the force-bearing spring 9, and then the external connecting arm and the connecting arm body 1 are fitted together, and then the connecting limit plate 13, the movable connecting rod 12, the movable ball 16 and the connecting limit plug rod 14 are inserted into the external connecting arm, the connecting arm body 1 and the fixed sleeve 3 to make a preliminary connection between the connecting arm body 1 and the external connecting arm. At this time, the movable ball 16 is located on the inner side of the external connecting arm, and then the connecting pull plate 10 is released. When the force-bearing mounting plate 8 is acted upon by the force-bearing spring 9, it can drive the reinforced limiting plug rod 11 and the movable pull rod 7 to reset, so that the reinforced limiting plug rod 11 can be quickly inserted into the inner side of the fixed through groove 17, thereby quickly connecting and fixing. Conversely, it can also be quickly disassembled, and the operation is convenient.

[0037] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
