Description

An intelligent soybean combine harvesting device

Technical Field

The invention belongs to the field of harvesting devices, and in particular relates to an intelligent soybean combine harvesting device.

Background Art

With the development of modern agricultural technology, soybean, as one of the most important food crops in the world, the improvement of its harvesting technology is of great significance to agricultural modernization. Traditional soybean harvesting methods are mostly manual or semi-mechanized operations, which have problems such as high labor intensity, low efficiency and high cost. In some foreign regions, due to the large-scale soybean planting, its soybean combine harvesting technology has been fully developed. However, due to the gradual increase in the domestic planting area, soybean harvesting needs to take into account the actual planting environment, and the relevant technology has not been fully developed. With the further development of existing automation and intelligent technologies, intelligent harvesting devices have gradually become an important tool for improving agricultural production efficiency.

Generally speaking, the working principle of a soybean combine harvester mainly involves the following steps: Harvesting: The soybean combine harvester cuts off and collects soybean plants from the field through its specific mechanical structure, such as cutters and conveying devices. Threshing: The cut soybean plants are sent to the threshing device, and the soybean kernels are separated from the plants through the threshing drum or other threshing mechanisms. Separation and cleaning: After threshing, the soybeans and stems and other debris are separated from the soybean kernels and impurities through air separation or other separation methods to obtain relatively pure soybeans. Collection: The pure soybean kernels are collected in the grain storage box inside the machine or directly sent to the transport vehicle through the conveying device.

For example, the Chinese patent publication number CN201630003U discloses a corn and soybean combine harvester, which includes a walking mechanism, a cab, a power transmission device, a header assembly, a threshing device, a cleaning device, a grain storage box, a straw chopping roller and other components. The header assembly further includes a cutter and a conveying plate. An auxiliary conveyor belt is provided on the frame above the conveying plate, and hook-shaped shifting teeth are evenly distributed on the auxiliary conveyor belt. This technology achieves the advantages of low stubble and less loss of beans and pods through the coordinated work of the left cutter and the right cutter.

Although the prior art has made some progress in soybean harvesting, there are still some problems to be solved. In particular, after soybean threshing, although a net is provided for screening soybeans in the above technology, the screening effect is insufficient and clogging is easy to occur during screening, which affects the harvesting efficiency and the quality of soybean harvest.

Summary of the invention

The purpose of the present invention is to provide an intelligent soybean combine harvester, which solves the problem of poor screening effect of soybeans after threshing in the existing soybean combine harvester.

In order to achieve the above-mentioned object, the present invention provides an intelligent soybean combine harvester, comprising a frame, a threshing drum is arranged on the frame, a support frame is fixedly connected to the surface of the frame and located below the threshing drum, a fixed seat is fixedly connected to the top of the support frame, a connecting seat is slidably sleeved inside the fixing seat, two hinged plates are hinged inside the connecting seat, a screen is arranged inside each of the hinged plates, a shaking mechanism is arranged on the connecting seat, and a feeding mechanism is arranged on the connecting seat;

The unloading mechanism comprises a bracket, the top of the connecting seat is fixedly connected with the bracket, the other end of the bracket is fixedly connected with a unloading barrel, the front end of the unloading barrel is fixedly connected with a mounting bracket, the upper end of the mounting bracket is fixedly installed with a motor, the output end of the motor is rotatably connected with the unloading barrel through a bearing, the outer side of the motor output end is fixedly connected with a rotating shaft, the rotating shaft is rotatably connected with the unloading barrel through a bearing, the circumferential surface of the rotating shaft is fixedly connected with a partition plate, the partition plate is rotatably connected with the unloading barrel, and the bottom of the unloading barrel is fixedly connected with a unloading guide plate;

The shaking mechanism includes a cylinder, the bottom of the inner wall of the fixed seat is fixedly connected to the cylinder, the upper end of the cylinder output end is fixedly connected to a top block, the top block is in contact with the connecting seat, the left and right ends of the connecting seat are fixedly connected to guide blocks, the guide block is slidably connected to the fixed seat, the guide block has a guide rod slidably sleeved inside the guide block, the guide rod is fixedly connected to the fixed seat, two symmetrically distributed first springs are arranged on the outside of the guide rod, and a second spring is arranged between the two hinged plates.

The principle of the present invention is that when in use, the soybeans can be harvested under the operation of the harvester, and then the soybeans will be transported to the threshing drum for threshing. After threshing, the soybeans will fall into the inside of the discharge barrel, and then the output end of the motor drives the rotating shaft and the partition plate to rotate, and the partition plate with soybeans is rotated to the lower end, and then the soybeans will be discharged through the discharge guide plate, and then the threshed soybeans can be automatically screened under the action of the screen, which is convenient for subsequent separate processing of the soybeans, realizing automatic harvesting and automatic screening of soybeans, which is more intelligent, and the rotation of the partition plate driven by the motor can realize the timed and quantitative feeding and screening of the soybeans, avoiding excessive accumulation of soybeans and affecting the screening effect.

During the soybean screening process, the output end of the cylinder drives the top block to move up, the top block drives the connecting seat to move up, the connecting seat drives the guide block to slide along the guide rod, and then the guide block squeezes the first spring on the top and stretches the other first spring, and then the output end of the cylinder drives the top block to move down quickly and separate from the connecting seat, and the connecting seat will move down quickly under the action of gravity and the elastic action of the first spring, and the elastic action of the first spring will also make the connecting seat constantly shake up and down, which can avoid the blockage of the screen and help improve the screening effect. By designing the unloading mechanism, it is convenient to discharge the material in a timely and quantitative manner.

The beneficial effects of the present invention are as follows: soybeans can be threshed by the threshing drum, and then the threshed soybeans can be automatically screened under the action of the screen, which is convenient for subsequent separate processing of the soybeans, and automatic screening of the soybeans after automatic harvesting can be achieved, which is more intelligent. In the screening process of the screen, the connecting seat can be moved upward under the drive of the cylinder, and under the action of the guide block, the guide rod and the first spring, the connecting seat and the screen can be shaken in the vertical direction, which can avoid clogging of the screen and help improve the screening effect.

By designing the discharge barrel, the soybeans after threshing can be received. Under the action of the partition plate, the internal space of the discharge barrel can be divided. When the motor drives the rotating shaft and the partition plate to rotate, the material between the two adjacent partition plates can be discharged through the discharge guide plate and can be screened randomly. The timed and quantitative screening of soybeans can be realized to avoid excessive accumulation of soybeans affecting the screening effect.

Furthermore, the top block is in the shape of a disk, and a rubber pad is embedded in the top block. By designing the top block, the connecting seat can be supported.

Further, one end of the first spring is fixedly connected to the fixing seat, and the other end of the first spring is fixedly connected to the guide block. By designing the first spring, the acting force of the first spring can act on the guide block.

Furthermore, the edges of the screen are fixedly connected to the hinged plates respectively, and the mesh diameter of the upper screen is larger than the mesh diameter of the lower screen; the hinged plate is arranged at an angle, and a screening discharge port is provided on the connecting seat, and the screening discharge port is located on the lower side of the hinged plate; a notch is provided on one side of the bottom of the connecting seat for material to pass through, and the bottom of the fixed seat is arranged at an angle, a bottom material outlet is provided on the lower side, and the higher side is located below the notch, a baffle plate is provided at the bottom material outlet, and the baffle plate is hinged to the fixed seat, and a limit block is provided on the fixed seat so that the baffle plate can only be folded inward; an exhaust port is provided on the side of the cylinder, and an exhaust solenoid valve is provided at the exhaust port, and the exhaust port faces one side of the notch.

The soybean grains after threshing usually have good fluidity. The threshing process separates the soybean grains from the bean pods, and the obtained materials are relatively uniform in size and shape. However, some impurities such as bean pod fragments, straw, dust, etc. may be mixed into the soybean material after threshing, and the humidity of the soybean grains will be affected during the threshing process. Soybean grains with high humidity need to be properly dried to prevent mildew and germination. In addition, the threshing machine will generate heat during operation, which will cause the temperature of the soybean grains after threshing to rise, affecting the quality. In this scheme, the threshed soybean grains enter the upper screen, and the aperture of the upper screen is larger, so as to separate the straw or bean pod fragments with larger diameter. Then enter the lower screen, and the aperture of the lower screen is smaller, so as to separate the soybean grains and dust. That is, the edge of the screen is fixedly connected to the hinged plate, and the mesh diameter of the upper screen is larger than the mesh diameter of the lower screen, so that the larger beans and bean pod fragments are intercepted by the upper screen, while the smaller dust and impurities are discharged through the lower screen.

The tilted setting of the hinged plate facilitates the flow of materials on the screen, and the screening outlet is located on the lower side of the hinged plate, which is convenient for the discharge of the screened materials. The shaking mechanism driven by the cylinder makes the connecting seat and the screen shake in the vertical direction, and the exhaust gas is discharged, which can prevent the screen from being blocked and improve the screening efficiency. The exhaust port of the cylinder is controlled by the exhaust solenoid valve, and the exhaust port is facing the side of the screening outlet. When the cylinder is working (downward), the exhausted exhaust gas enters the bottom of the fixed seat. Due to the increase in air pressure in the fixed seat, the exhaust gas moves upward from the notch, driving the dust to contact with the soybean grains, absorbing the moisture on the surface of the soybean grains, and taking away the residual heat of the soybean grains. And due to the action of the cylinder, the first spring and the second spring, even if the dust is adsorbed on the surface of the soybean grains, this state of continuous up and down movement will cause the dust after absorbing water to separate from the surface of the soybean grains (the weight increases after absorbing water).

The bottom material outlet at the bottom of the fixed seat is equipped with a baffle plate that can be folded inward. The baffle plate is closed when the air pressure in the fixed seat is high, so as to control the airflow direction and make full use of the dry dust. When the exhaust gas discharged from the cylinder drives the dust to move upward, the dust absorbs water and increases in weight, and leaks out from the screen. When the cylinder moves upward, negative pressure is generated, causing the bottom material outlet to open, and the dust that has absorbed water is discharged through the bottom material outlet.

Further, one end of the second spring is fixedly connected to one of the hinge plates, and the other end of the second spring is fixedly connected to the other hinge plate. By designing the second spring, the force of the second spring can act on the hinge plate.

Furthermore, an arc-shaped guide plate is provided at the notch, and the guide plate is fixed to the connection seat. The guide plate can diversify the direction of the airflow and generate more turbulence when the connection seat moves. When the cylinder exhaust gas is discharged, the guide plate also moves downward synchronously, which can increase the speed of the airflow and better make the dust contact with the soybean grains.

Furthermore, the number of the partition plates is multiple, and the multiple partition plates are annular and evenly distributed on the rotating shaft. By designing the partition plates, the internal space of the lower barrel can be divided.

The specific implementation process of the present invention is as follows: when in use, the soybeans can be harvested under the operation of the harvester, and then the soybeans will be transported to the threshing drum 2 for threshing. After threshing, the soybeans will fall into the inside of the discharge barrel 92, and then the output end of the motor 94 drives the rotating shaft 95 and the partition plate 96 to rotate, and the partition plate 96 loaded with soybeans is rotated to the lower end, and then the soybeans will be discharged through the discharge guide plate 97, and then the threshed soybeans can be automatically screened under the action of the screen 7, which is convenient for the subsequent separate processing of the soybeans, and the automatic harvesting and automatic screening of the soybeans can be realized, which is more intelligent, and the rotation of the partition plate 96 driven by the motor 94 can realize the timed and quantitative feeding and screening of the soybeans, and avoid the excessive accumulation of soybeans affecting the screening effect.

Specifically, after threshing, the beans enter the upper screen 7, which has a larger aperture, so as to separate the straw or bean pod fragments with a larger diameter. Then, the beans enter the lower screen 7, which has a smaller aperture and can separate the soybean grains and dust. That is, the edge of the screen 7 is fixedly connected to the hinge plate 6, and the mesh diameter of the upper screen 7 is larger than that of the lower screen 7, so that the larger beans and bean pod fragments are intercepted by the upper screen 7, while the smaller dust and impurities are discharged through the lower screen 7.

The tilted setting of the hinged plate 6 facilitates the flow of materials on the screen 7, and the screening outlet is located on the lower side of the hinged plate 6, which is convenient for the discharge of the screened materials. The shaking mechanism 8 driven by the cylinder 81 makes the connecting seat 5 and the screen 7 shake in the vertical direction, and the exhaust gas is discharged, which can prevent the screen 7 from being blocked and improve the screening efficiency. The exhaust port of the cylinder 81 is controlled by the exhaust solenoid valve, and the exhaust port faces the side of the screening outlet. When the cylinder 81 is working (downward), the exhausted exhaust gas enters the bottom of the fixed seat 4. Due to the increase in air pressure in the fixed seat 4, the exhaust gas moves upward from the notch, driving the dust to contact with the soybean grains, absorbing the moisture on the surface of the soybean grains, and taking away the residual heat of the soybean grains. And due to the action of the cylinder 81, the first spring 85 and the second spring 86, even if the dust is adsorbed on the surface of the soybean grains, this state of continuous up and down movement will also cause the dust after absorbing water to separate from the surface of the soybean grains (the weight increases after absorbing water).

The bottom material outlet at the bottom of the fixed seat 4 is provided with a baffle plate that can be folded inwards. The baffle plate is closed when the air pressure in the fixed seat 4 is high, so as to control the airflow direction and make full use of the dry dust. When the exhaust gas discharged from the cylinder 81 drives the dust to move upward, the dust absorbs water and increases in weight, and leaks out from the screen 7. When the cylinder 81 moves upward, negative pressure is generated, so that the bottom material outlet is opened, and the dust after absorbing water is discharged through the bottom material outlet.

The beneficial effects of the present invention are as follows: by designing the function of the threshing drum 2, the soybeans can be threshed, and then the threshed soybeans can be automatically screened under the action of the screen 7, which is convenient for subsequent separate processing of the soybeans, and realizes automatic harvesting and automatic screening of the soybeans, which is more intelligent. In the screening process of the screen 7, under the drive of the cylinder 81, the connecting seat 5 can be moved up, and under the action of the guide block 83, the guide rod 84 and the first spring 85, the connecting seat 5 and the screen 7 can be shaken in the vertical direction, which can avoid blockage of the screen 7 and help improve the screening effect.

By designing the function of the discharge barrel 92, the threshed soybeans can be received, and the internal space of the discharge barrel 92 can be divided under the action of the partition plate 96. When the motor 94 drives the rotating shaft 95 and the partition plate 96 to rotate, the material between two adjacent partition plates 96 can be discharged through the discharge guide plate 97, and screening can be carried out randomly, thereby realizing timed and quantitative screening of soybeans and avoiding excessive accumulation of soybeans that affects the screening effect.
