Description

Technical Field

[0001] The utility model relates to the technical field related to harvester choppers, and in particular to an intelligent lifting device for harvester choppers. Background Art

[0002] The harvester chopper is an important part of the combine harvester, mainly used to chop the stems and stubble of crops for returning to the field or other processing. The chopper is usually composed of a moving blade, a fixed blade and a transmission device. When working, the moving blade rotates at high speed through the transmission device, forming a shearing effect with the fixed blade to chop the stems. The design and performance of the chopper will affect the harvester's operating efficiency, chopping quality and energy consumption. The chopper needs to use a lifting device when avoiding obstacles. Therefore, an intelligent lifting device for the harvester chopper is particularly needed.

[0003] However, the existing harvester choppers, most of which are currently fixed directly on the tail of the harvester, cannot avoid obstacles by themselves, which can easily cause the chopper to malfunction or be damaged after encountering obstacles. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent lifting device for a harvester chopper to solve the problem of the existing harvester choppers proposed in the above background technology. At present, most harvester choppers are directly fixed on the tail of the harvester. When encountering obstacles, they cannot avoid them by themselves, which can easily lead to the problem that the choppers malfunction or are damaged after encountering obstacles.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent lifting device for a harvester chopper, comprising a harvester body, a chopper body connected to one side of the surface of the harvester body, a controller connected to one side of the surface of the harvester body, a lifting mechanism arranged on one side of the surface of the chopper body, and a chopping mechanism arranged inside the chopper body;

[0006] The lifting mechanism includes an infrared sensor, a hollow column, a synchronous motor, a screw rod and a slider. One side of the surface of the chopper body is connected to the infrared sensor, one side of the surface of the harvester body is connected to the hollow column, one side of the surface of the hollow column is installed with a synchronous motor, one end of the synchronous motor is connected to the screw rod, and one end of the screw rod is connected through the slider.

[0007] Preferably, one side of the surface of the sliding block is fixedly connected to the chopper body, and one end of the synchronous motor passes through the hollow column and is connected to the lead screw.

[0008] Preferably, the synchronous motor is electrically connected to a controller, and the infrared sensor is electrically connected to the controller.

[0009] Preferably, the shredder mechanism comprises a power motor, an inclined slot, a connecting rod and a blade. The power motor is installed on one side of the surface of the shredder body, an inclined slot is provided inside the shredder body, one end of the power motor is connected to the connecting rod, and one end of the connecting rod is connected to the blade.

[0010] Preferably, one end of the power motor passes through the chopper body and is connected to a connecting rod, and the blade is made of alloy material.

[0011] Compared with the prior art, the beneficial effects of the utility model are: compared with the traditional method of directly fixing the chopper behind the harvester, the harvester chopper can adjust its height by itself to avoid obstacles. The infrared sensor only needs to detect and scan the bottom of the harvester in real time, and then transmit the data of the bottom of the harvester to the controller. When encountering an obstacle, the controller will automatically control the power motor to start, so that the chopper body can rise and stay away from the obstacle, thereby ensuring the safety of the chopper body.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: an intelligent lifting device for a harvester chopper, comprising a harvester body 1, a chopper body 2 is connected to one side of the surface of the harvester body 1, a controller 3 is connected to one side of the surface of the harvester body 1, a lifting mechanism 4 is arranged on one side of the surface of the chopper body 2, and a chopper mechanism 5 is arranged inside the chopper body 2;

[0019] The lifting mechanism 4 includes an infrared sensor 401, a hollow column 402, a synchronous motor 403, a screw rod 404 and a slider 405. The surface side of the chopper body 2 is connected with the infrared sensor 401, the surface side of the harvester body 1 is connected with the hollow column 402, the surface side of the hollow column 402 is installed with a synchronous motor 403, one end of the synchronous motor 403 is connected with a screw rod 404, and one end of the screw rod 404 is connected with a slider 405. When the chopper body 2 is intelligently lifted, first, when the harvester body 1 is in motion, the infrared sensor 401 will scan and detect the bottom of the harvester body 1 in real time. When encountering a concave When the road surface is uneven, the infrared sensor 401 will send a signal to the controller 3 after scanning, and then the controller 3 will automatically control the synchronous motor 403 to be energized, the synchronous motor 403 starts to start, and then the synchronous motor 403 starts to drive the screw rod 404 to rotate. While the screw rod 404 rotates, it will drive the slider 405 to slide horizontally, and the slider 405 will drive the chopper body 2 to rise at the same time, so as to stay away from the uneven road surface and avoid the chopper body 2 from hitting the road surface and causing damage. When the infrared sensor 401 continues to scan and finds that there is no obstacle on the road ahead, the controller 3 will control the synchronous motor 403 to rotate in the opposite direction and reset.

[0020] Furthermore, one side of the surface of the slider 405 is fixedly connected to the chopper body 2, and one end of the synchronous motor 403 passes through the hollow column 402 and is connected to the screw rod 404. Through the arrangement of the screw rod 404 and the slider 405, when in use, the screw rod 404 can drive the slider 405 to move horizontally, thereby facilitating the subsequent slider 405 to drive the chopper body 2 to rise and fall. When the slider 405 is driven to rise by the screw rod 404, the slider 405 can drive the chopper body 2 to rise, and at this time the chopper body 2 can be away from the uneven road surface.

[0021] Furthermore, the synchronous motor 403 is electrically connected to the controller 3, and the infrared sensor 401 is electrically connected to the controller 3. Through the setting of the infrared sensor 401, when in use, the infrared sensor 401 can scan the bottom road condition of the harvester body 1 in real time, and then transmit the road condition to the controller 3, and the controller 3 decides whether to automatically rise and fall, so that when encountering obstacles, the controller 3 can control the start of the synchronous motor 403 to complete the lifting of the chopper body 2.

[0022] Furthermore, the chopping mechanism 5 includes a power motor 501, an inclined slot 502, a connecting rod 503 and a blade 504. The power motor 501 is installed on one side of the surface of the chopper body 2, and the chopper body 2 is provided with an inclined slot 502. One end of the power motor 501 is connected to the connecting rod 503, and one end of the connecting rod 503 is connected to the blade 504. Through the arrangement of the power motor 501, the inclined slot 502, the connecting rod 503 and the blade 504, when in use, after the harvester body 1 has harvested the wheat, and after a series of screenings, the wheat straw finally enters the inclined slot 502 inside the chopper body 2, the power motor 501 will be started, the power motor 501 starts to rotate, and then the power motor 501 drives the connecting rod 503 to rotate, and the connecting rod 503 drives the blade 504 to rotate, and then the blade 504 will move along the corresponding inclined slot 502, and then crush the wheat straw for subsequent processing, storage or returning to the field.

[0023] Furthermore, one end of the power motor 501 passes through the chopper body 2 and is connected to the connecting rod 503. The blade 504 is made of an alloy. Through the arrangement of the blade 504, when in use, the alloy blade 504 has higher strength and toughness, and also has better wear resistance and corrosion resistance, which can allow the blade 504 to be used for a longer period of time. At the same time, it can also prevent the blade 504 from crushing the blade 504 with stones when straw mixed with stones enters the chopper body 2, and it will not be easy to have gaps.

[0024] Working principle: First, after the harvester body 1 harvests the wheat and passes through a series of screenings, when the wheat straw finally enters the inclined slot 502 inside the chopper body 2, the power motor 501 will be started, the power motor 501 will start to rotate, and then the power motor 501 will drive the connecting rod 503 to rotate, and the connecting rod 503 will drive the blade 504 to rotate, and then the blade 504 will move along the corresponding inclined slot 502, and then crush the wheat straw for subsequent processing, storage or returning to the field, and then when the chopper body 2 is intelligently lifted and lowered, first, when the harvester body 1 is in motion, the infrared sensor 401 will scan and detect the harvester body 1 in real time. At the bottom, when encountering an uneven road surface, the infrared sensor 401 will send a signal to the controller 3 after scanning, and then the controller 3 will automatically control the synchronous motor 403 to be energized, the synchronous motor 403 starts to start, and then the synchronous motor 403 starts to drive the screw rod 404 to rotate. While the screw rod 404 rotates, it will drive the slider 405 to slide horizontally, and the slider 405 will simultaneously drive the chopper body 2 to rise, so as to stay away from the uneven road surface and avoid the chopper body 2 from hitting the road surface and causing damage. When the infrared sensor 401 continues to scan and finds that there is no obstacle on the road ahead, the controller 3 will control the synchronous motor 403 to rotate in the opposite direction and reset.
