Description

Technical Field

[0001] This utility model relates to the field of harvester header technology, and in particular to a harvester header anti-clogging mechanism. Background Technology

[0002] Depending on the type of crop being harvested, harvesting platforms can be categorized into rigid and flexible platforms for wheat, etc. Modern combine harvesters are equipped with harvesting platforms for different purposes and with different cutting widths. They require easy and quick assembly and disassembly, so quick-attachment devices are provided on the platforms. They do not require neat transport of crop stalks, and therefore are widely used.

[0003] During crop harvesting, the header of the harvester first cuts off the crop stalks, sending the crop into the threshing unit for processing. The header is the front part of the harvester, mainly responsible for cutting the crop stalks off the ground. Modern harvester headers mostly use horizontal or vertical blades, which can be flexibly adjusted according to the growth conditions of different crops. However, during operation, it is necessary to clean the soil, weeds, and straw fragments between the cutter blades and the blade guard in time after the operation. Use tools such as flathead screwdrivers and hammers to remove foreign objects stuck in the gaps between the blades. Stubbornly stuck objects can cause jamming and affect work efficiency.

[0004] To address this issue, we propose a harvester header anti-clogging mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a harvester header anti-blocking mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A harvester header anti-clogging mechanism includes a harvester header, inside which a winch blade is installed. One side of the winch blade is connected to a rotating wheel, and the rotating wheel is effectively connected by a belt. A lifting device is fixedly installed at the top of the harvester header. Fixed discs are fixedly installed on both sides of the inside of the lifting device. The fixed discs are sleeved on both ends of a ball screw. A sliding block is installed on the surface of the ball screw, and a cleaning plate is connected to one side of the sliding block through a support rod.

[0007] Preferably, the interior of the rotating wheel is effectively connected by a belt, and one side of the rotating wheel is connected to the output port of the drive motor through a connecting pipe.

[0008] Preferably, a placement box is fixedly installed on the outside of the rotating wheel, and the surface of the placement box has holes that are adapted to the size of the connecting pipe.

[0009] Preferably, the surface of the lifting device is provided with a through groove, and the size of the through groove is adapted to the size of the sliding block.

[0010] Preferably, the surface of the sliding block is provided with a screw hole adapted to the ball screw, and the surface diameter of the fixed disk is larger than the surface diameter of the sliding block.

[0011] Preferably, the upper end of the fixed disc has a hole, and a rotating handle is fixedly installed inside the hole, with an anti-slip pad wrapped around the surface of the rotating handle.

[0012] Preferably, the surface of the rotary handle has a hole, and a limit rod is inserted into the hole.

[0013] Preferably, a support rod is fixedly installed on one side of the sliding block, and a cleaning plate is fixedly connected to the surface of the support rod. A cleaning brush is installed below the cleaning plate, and the cleaning brush is made of soft bristles.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with a pull-out limit rod. By rotating the rotary handle, the ball screw inside the lifting device can be effectively rotated. When the winch blade is not working, the sliding block installed on the surface of the ball screw drives the support rod to descend effectively, allowing the cleaning plate to effectively clean the surface of the winch blade, preventing foreign objects from entering the blade gap. For stubborn adhering materials, a high-pressure water gun can be used to wash the bottom of the cutting table and the conveyor trough, improving work efficiency.

[0015] 2. This device is equipped with a drive motor that starts the rotating wheel inside the box, which is connected to the side of the winch blade by a belt. This drives the winch blade to rotate effectively, allowing for efficient power control and making it easier to control the cutting of different crops, thus improving work efficiency.

[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 Figure 1-6 A harvester header anti-clogging mechanism includes: a harvester header 1, with a winch blade 11 installed inside the harvester header 1. One side of the winch blade 11 is connected to a rotating wheel 13 for effective cutting of crops. The rotating wheel 13 is effectively connected by a belt 14 to protect it from damage caused by external forces. A lifting device 2 is fixedly installed at the top of the harvester header 1 for lifting... Fixed discs 21 are fixedly installed on both sides of the inside of the device 2. The fixed discs 21 are sleeved on both ends of the ball screw 22, so that both ends of the ball screw 22 are sleeved inside the fixed discs 21. The ball screw 22 is effectively rotated by the internal bearing connection. Sliding blocks 23 are installed on the surface of the ball screw 22. A cleaning plate 27 is connected to one side of the sliding block 23 through a support rod 26 to prevent foreign objects from entering the blade gap. For stubborn adhesives, the bottom of the cutting table and the conveying trough can be washed with a high-pressure water gun to improve work efficiency.

[0020] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the interior of the rotating wheel 13 is effectively connected by the belt 14, and one side of the rotating wheel 13 is connected to the output port of the drive motor 15 through the connecting pipe, which facilitates effective power control and makes it easier to control different crops being cut, thereby improving work efficiency.

[0021] Furthermore, refer to Figure 3 It can be seen that a placement box 12 is fixedly installed on the outside of the rotating wheel 13. The surface of the placement box 12 has holes, and the holes are adapted to the size of the connecting pipe, so as to effectively protect the internal rotating wheel 13 and prevent external forces from damaging the internal rotating wheel 13.

[0022] Furthermore, refer to Figure 4 It can be seen that the surface of the lifting device 2 is provided with a through groove, and the size of the through groove is adapted to the size of the sliding block 23 to prevent the sliding block 23 from rubbing against the edge of the lifting device 2 when it moves, thus avoiding jamming.

[0023] Furthermore, refer to Figure 5 It can be seen that the surface of the sliding block 23 is provided with a screw hole that matches the ball screw 22 to prevent the sliding block 23 from getting stuck on the surface of the ball screw 22 when it moves. The surface diameter of the fixed disc 21 is larger than the surface diameter of the sliding block 23, so that the sliding block 23 can be prevented from detaching from the surface of the ball screw 22 when it moves, thus preventing it from falling off. The upper end of the fixed disc 21 is provided with a hole, and a rotating handle 24 is fixedly installed inside the hole. The surface of the rotating handle 24 is wrapped with an anti-slip pad to prevent the operator's hands from being wet or sweaty when rotating it, thus preventing the operator's hands from slipping.

[0024] Furthermore, refer to Figure 5 It can be seen that the surface of the rotating handle 24 has holes, and the limit rod 25 is inserted into the inside of the holes, which makes it easy to fix it effectively when it is adjusted to a suitable position, and prevents it from loosening or shaking.

[0025] Furthermore, refer to Figure 6 It can be seen that a support rod 26 is fixedly installed on one side of the sliding block 23, and a cleaning plate 27 is fixedly connected to the surface of the support rod 26. A cleaning brush is installed below the cleaning plate 27, and the cleaning brush is made of soft bristles to prevent foreign objects from being present in the blade gap. For stubborn adhesives, the bottom of the cutting table and the conveying trough can be rinsed with a high-pressure water gun to improve work efficiency.

[0026] Working principle: When in use, the drive motor 15 is started, which enables the rotating wheel 13 inside the placement box 12 to rotate effectively via the belt 14, thereby enabling the agitator blade 11 inside the harvester header 1 to rotate effectively. After the work is completed, the limit rod 25 is pulled out, and the rotating handle 24 is turned, which enables the ball screw 22 inside the lifting device 2 to rotate effectively. The two ends of the ball screw 22 are sleeved inside the fixed disc 21. When the ball screw 22 rotates, it drives the sliding block 23 installed on the surface of the ball screw 22 to move effectively. As the sliding block 23 moves, it drives the support rod 26 on one side of the sliding block 23 to move effectively and synchronously. At the same time, when the support rod 26 moves, it drives the cleaning plate 27 to descend, cleaning the surface of the agitator blade 11.

[0027] The above is the complete working principle of this utility model.
