Description

Technical Field

[0001] This utility model relates to the technical field of corn thresher frame, and in particular to an anti-threshing frame for a corn thresher. Background Technology

[0002] A corn thresher is an agricultural machine that separates the kernels from the cob of a corn cob through mechanical impact, rubbing, or rotation of an axial flow drum. The anti-threshing frame is one of the important components of the corn thresher, which supports and facilitates the movement of the corn thresher.

[0003] Existing corn threshers typically use bolts to directly connect to the lower anti-threshing frame. This rigid connection structure has obvious defects. During equipment operation, due to the lack of effective positioning and vibration damping components, the machine is prone to displacement due to vibration. Especially when performing high-intensity threshing operations on uneven ground, there is also a risk of tipping over. Therefore, to solve this problem, designing an anti-threshing frame for corn threshers is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-threshing frame for corn threshers. This frame incorporates a limiting mechanism to conveniently and stably limit the movement of the corn thresher body and absorb vibrations, preventing displacement or tipping. It also includes two positioning components to further improve the stability of the equipment in special working environments, making it highly adaptable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corn thresher anti-threshing frame includes a base, a support frame above the base, and a fixed connection between the support frame and the base via a fixing frame. The main body of the corn thresher is disposed inside the support frame. A limiting mechanism includes two clamping plates disposed inside the support frame. A first rubber shock-absorbing pad is fixedly disposed on the side wall of each of the two clamping plates. A first threaded rod is rotatably connected to the other side of each of the two clamping plates. The other end of each of the two first threaded rods passes through the support frame and is fixedly connected to a first rotating disk. The threaded ends of the two first threaded rods are threadedly connected to the support frame. Two positioning components are used to fix the base.

[0007] Preferably, guide rods are fixedly connected to the side walls of both clamping plates, and both guide rods pass through the support frame and are slidably connected to the support frame.

[0008] Preferably, a second rubber shock-absorbing pad is fixedly provided on the left inner wall, the rear inner wall, and the inner bottom of the support frame.

[0009] Preferably, both of the first rubber shock-absorbing pads and the plurality of second rubber shock-absorbing pads are attached to the outer side of the corn thresher body.

[0010] Preferably, the positioning component includes a second threaded rod that passes through the upper end of the base, the threaded end of the second threaded rod being threadedly connected to the base, a second rotating disk being fixedly connected to the upper end of the second threaded rod, and a tapered connecting block being fixedly connected to the lower end of the second threaded rod.

[0011] Preferably, the lower end of the base is equipped with multiple casters.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A limiting mechanism is installed, which moves two clamping plates by rotating two first rotating disks, thus easily achieving stable clamping and limiting of the main body of the corn thresher. In addition, multiple first rubber shock-absorbing pads and multiple second rubber shock-absorbing pads can effectively absorb the high-frequency vibrations generated during equipment operation, preventing displacement or tipping due to vibration and ensuring the stability of the equipment during operation. Two positioning components are also set up. By rotating the second rotating disk, the conical connecting block and the second threaded rod are inserted into the ground, which can further improve the stability of the entire equipment in special working environments. Overall, the applicability is good. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A corn thresher anti-threshing frame includes a base 1. Multiple casters 14 are installed at the lower end of the base 1 to facilitate the movement of the entire equipment. The casters 14 are equipped with stop plates to ensure the stability of the entire equipment on flat ground. A support frame 2 is installed above the base 1. The support frame 2 is fixedly connected to the base 1 by a fixing frame 3. Second rubber shock-absorbing pads 10 are fixedly installed on the left inner wall, rear inner wall and bottom of the support frame 2. The corn thresher body 4 is installed inside the support frame 2. Two first rubber shock-absorbing pads 6 and multiple second rubber shock-absorbing pads 10 are all in contact with the outer side of the corn thresher body 4, which can effectively absorb the high-frequency vibration generated by the corn thresher body 4 during operation, thereby preventing the entire equipment from shifting or tipping over.

[0020] The system also includes a limiting mechanism, which includes two clamping plates 5 disposed within the support frame 2. Each clamping plate 5 has a first rubber shock-absorbing pad 6 fixedly disposed on its side wall. Each clamping plate 5 has a first threaded rod 7 rotatably connected to its other side. The other ends of the two first threaded rods 7 pass through the support frame 2 and are fixedly connected to a first rotating disk 8. The threaded ends of the two first threaded rods 7 are threadedly connected to the support frame 2. Each clamping plate 5 has a guide rod 9 fixedly connected to its side wall. Both guide rods 9 pass through the support frame 2 and are slidably connected to the support frame 2. The guide rods 9 can ensure the stability of the clamping plates 5 when they move.

[0021] The device also includes two positioning components, both of which are used to fix the base 1. Each positioning component includes a second threaded rod 11 that passes through the upper end of the base 1. The threaded end of the second threaded rod 11 is threadedly connected to the base 1. A second rotating disk 12 is fixedly connected to the upper end of the second threaded rod 11, and a tapered connecting block 13 is fixedly connected to the lower end of the second threaded rod 11. By controlling the tapered connecting block 13 and the second threaded rod 11 to be inserted into the ground, the stability of the entire device can be further improved.

[0022] In this invention, upon initial use, the corn thresher body 4 is first placed on the second rubber shock-absorbing pad 10 at the bottom of the support frame 2. Then, the first rotating disc 8 on the right side is rotated, causing the corresponding first threaded rod 7 to rotate, which in turn moves the clamping plate 5 on the right side to the left until the first rubber shock-absorbing pad 6 on the right side is tightly fitted to the right side of the corn thresher body 4. This, combined with the second rubber shock-absorbing pad 10 on the left side, achieves stable clamping and limiting of the corn thresher body 4 in the left and right directions. Similarly, referring to the above operation, by rotating the first rubber shock-absorbing pad 10 on the front side... A rotating disk 8 drives the front clamping plate 5 to move backward, which, together with the first rubber shock-absorbing pad 6 on the front and the second rubber shock-absorbing pad 10 on the rear, can achieve stable clamping and limiting of the corn thresher body 4 in the front-back direction. In this way, the stable clamping and limiting of the corn thresher body 4 is completed. Through the close cooperation of multiple first rubber shock-absorbing pads 6 and multiple second rubber shock-absorbing pads 10 with the corn thresher body 4, the high-frequency vibration generated during the operation of the equipment can be absorbed, thereby ensuring that the whole device remains stable during operation and avoiding displacement or tipping.

[0023] It is worth mentioning that during daily use, multiple casters 14 facilitate the movement of the entire device, and each caster 14 is equipped with a stop plate to ensure the stability of the entire device on flat ground. When the working environment is uneven ground, the operator can rotate the two second rotating discs 12 in sequence to drive the corresponding second threaded rods 11 and conical connecting blocks 13 to move down synchronously, so that the conical connecting blocks 13 and the second threaded rods 11 are firmly inserted into the ground. This can significantly enhance the anti-overturning ability of the entire device under complex terrain conditions, thereby effectively improving its stability under special working conditions.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
