DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1 See also Figure 1~Figure 3 , a corn thresher for preventing corn damage, comprising: A threshing box 1, one side of the threshing box 1 is open, a side plate 2 is fixed to the open end of the threshing box 1, and a threshing assembly 3 is mounted on the side plate 2; The collecting box 4 is fixed at the bottom end of the threshing box 1, and a collecting box 5 is slidably inserted into the side wall of the collecting box 4; The transverse driving assembly 8 is fixed to the side wall of the collecting box 4 through the transverse plate 7. A mounting plate 9 is installed above the transverse driving assembly 8, and a corn rotating assembly 10 is installed on the mounting plate 9.

[0024] The bottom wall of the inner cavity of the threshing box 1 is inclined, and a feeding chute 11 communicating with the inside of the collecting box 4 is provided through the bottom wall of the inner cavity of the threshing box 1 .

[0025] A handle 6 is fixed to the side wall of the collection box 5 .

[0026] In this embodiment, the threshing box 1 is used to provide an operating environment for corn threshing, the side plate 2 is convenient for the installation of the threshing assembly 3, the threshing assembly 3 is capable of threshing corn, and can also thresh corn of different diameters, thereby avoiding damage to corn kernels during the threshing process, the collecting box 5 is arranged in the collecting box 4, and can collect the threshed corn kernels, the transverse driving assembly 8 is used to drive the corn to be separated to move in the direction of the separation assembly 3, and the corn rotating assembly 10 is coordinated to drive the corn to rotate, thereby realizing the threshing operation of the corn. The bottom wall of the inner cavity of the threshing box 1 is arranged in an inclined manner, which can facilitate the corn kernels after threshing to fall into the collecting box 5 through the feeding chute 11 for collection, and the handle 6 arranged on the collecting box 5 can facilitate the removal of the collecting box 5.

[0027] In this embodiment, one side of the threshing box 1 is open, and the side plate 2 is fixed at the open end, and the threshing assembly 3 is assembled on the side plate 2. The bottom wall of the threshing box is designed to be in an inclined state. Such a design not only helps the corn kernels to flow naturally into the collection box 5 and reduce resistance, but also ensures that the threshed corn kernels flow smoothly into the collection box 4. The inclination angle of the threshing box 1 can be adjusted according to different working environments to ensure that the threshed corn kernels can fall into the collection box through the feed chute 11 without hindrance. In order to improve the durability of the threshing box 1, wear-resistant steel plate or polycarbonate material is used. The inner wall can be smoothed to reduce the friction between the corn and the box body, thereby reducing the damage to the corn during the threshing process. At the same time, the side plate 2 can be set as an adjustable structure, and the position of the side plate 2 can be adjusted according to the diameter of the corn, the working requirements of the thresher and the different requirements of the threshing operation. And the position of the threshing assembly 3 on the side plate 2 can also be installed and disassembled as needed, which is convenient for maintenance and replacement of the threshing cutter head.

[0028] Example 2 like Figure 4~Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes: The threshing assembly 3 includes an annular plate 31, which is rotatably mounted at the center of the side plate 2, and a mounting sleeve 32 is rotatably mounted at the center of the annular plate 31; The mounting sleeve 32 is fixedly connected to the side wall of the side plate 2 through the connecting frame 36, and a plurality of sliding sleeves 33 are symmetrically installed on the center of the side wall of the mounting sleeve 32; A lever 34 is slidably mounted in the sliding sleeve 33; One end of the lever 34 is rotatably connected to the side wall of the annular plate 31, and the other end of the lever 34 is fixed with a threshing blade 35; A rotating mechanism for driving the annular plate 31 to rotate is installed on the top of the inner wall of the side plate 2 .

[0029] The rotating mechanism includes teeth 37, which are fixed to the top of the annular plate 31, and the teeth 37 are meshedly connected with a rack 38; An electric push rod 310 is fixed to one end of the rack 38, and a telescopic rod 311 is fixed to the other end of the rack 38; A vertical plate 39 is fixed to the ends of the electric push rod 310 and the telescopic rod 311 away from the rack 38; The vertical plate 39 is symmetrically fixed on the top of the side wall of the side plate 2.

[0030] A plurality of mounting grooves 12 are symmetrically formed through the side wall of the mounting sleeve 32 , and the sliding sleeve 33 is rotatably mounted in the mounting grooves 12 .

[0031] In this embodiment, the threshing assembly 3 can perform threshing operations on corn, and it can also perform threshing operations on corns of different diameters, thereby avoiding damage to corn kernels during the threshing process. The threshing assembly 3 drives the annular plate 31 to rotate through the rotating mechanism provided, thereby adjusting the position of the threshing blade head 35. When adjusting the position of the threshing blade head 35, the electric push rod 310 is controlled to extend and retract, thereby driving the rack 38 to move. During the movement of the rack 38, the annular plate 31 is driven to rotate through the teeth 37 provided. During the rotation of the annular plate 31, the lever 34 is synchronously deflected under the action of the sleeve 33, thereby making the threshing blade heads 35 approach or move away from each other, thereby achieving threshing operations on corns of different diameters and ensuring the integrity of the corn kernels during the threshing process.

[0032] The transverse drive assembly 8 includes two symmetrically arranged mounting seats 81, which are respectively fixed on both sides of the top wall of the transverse plate 7, and a lead screw 82 is rotatably mounted between the two mounting seats 81; A lead screw nut 83 is threadedly connected to the lead screw 82, and guide rods 84 are symmetrically installed on both sides of the lead screw 82; The guide rod 84 is fixed between the two mounting seats 81, and the guide rod 84 slides through the lead screw nut 83; A first motor 85 is fixed on the outer wall of the mounting seat 81 on one side. The power shaft of the first motor 85 passes through the corresponding mounting seat 81 through a bearing and is fixedly connected to one end of the lead screw 82 .

[0033] The mounting plate 9 is fixed on the top wall of the screw nut 83 .

[0034] The corn rotating assembly 10 includes a sleeve 101, which is rotatably mounted on the top of the side wall of the mounting plate 9, a pin 102 is fixed at the center of the inner wall of the sleeve 101, and two limit pins 103 are symmetrically fixed on the inner wall of the sleeve 101; A second motor 104 is fixed to a side of the mounting plate 9 away from the sleeve 101 . The power shaft of the second motor 104 penetrates the mounting plate 9 through a bearing and is fixedly connected to the axial center position of the side wall of the sleeve 101 .

[0035] The first motor 85 and the second motor 104 are both servo motors or stepper motors.

[0036] In this embodiment, the transverse drive assembly 8 is used to drive the corn to be separated to move in the direction of the separation assembly 3, and cooperate with the corn rotating assembly 10 to drive the corn to rotate, so as to realize the threshing operation of the corn. When the corn separation operation is required, firstly, one end of the corn is inserted into the insertion pin 102 and the limit pin 103, and the limit pin 103 can prevent the corn from slipping during the rotation of the corn, and then the second motor 104 is controlled to work, and the second motor 104 drives the sleeve 101 to rotate, thereby driving the corn to rotate, and then the first motor 85 is controlled to rotate, and the first motor 85 drives the lead screw 82 to rotate. During the rotation of the lead screw 82, the mounting plate 9 is driven to move in the direction of the threshing assembly 3 through the lead screw nut 83, thereby driving the corn to enter the threshing assembly 3 for threshing operation.

[0037] In this embodiment, the transverse drive assembly 8 is a screw transmission system driven by a servo motor. The screw 82 drives the screw nut 83 to move, thereby pushing the mounting plate 9 to move toward the threshing assembly 3, driving the corn into the threshing area. This design allows the corn to move evenly along a predetermined path, thereby reducing the uneven mechanical impact on the corn during the threshing process and avoiding damage to the corn kernels.

[0038] Example 3 like Figure 1 to Figure 8 As shown, based on the same concept as the above-mentioned embodiments 1 and 2, this embodiment further proposes: A corn thresher for preventing corn from being damaged, further comprising: A sensor is installed in the threshing box 1 and is used to detect the size of the threshed corn; The controller signals are connected to the sensor, the electric push rod 310 , the first motor 85 and the second motor 104 .

[0039] In this embodiment, the intelligent control system is formed by sensors and controllers, and the user can adjust the working parameters of the thresher in real time, such as the spacing of the threshing heads, the speed of corn rotation, and the propulsion speed of the lateral drive, etc., to ensure that the machine always operates in the best working state. At the same time, the thresher in this embodiment can also be equipped with a remote control function, and remote operation and monitoring can be achieved through a wireless communication module (such as Wi-Fi or Bluetooth), so that the user can adjust the equipment parameters and view the working status without personally operating the thresher. By combining the sensor and the controller, the position of the threshing head 35 can be automatically adjusted according to the diameter of the corn. The sensor detects the size of the corn in real time, and the controller controls the extension and contraction of the electric push rod 310 through the feedback signal, thereby driving the rack 38 and the teeth 37 to adjust the rotation of the annular plate 31, accurately adjusting the position of the threshing head, and ensuring that the corn kernels will not be damaged during the corn threshing process, nor will the threshing be incomplete. This adjustment function is not only suitable for corns of different diameters, but also can automatically adjust the strength and position of the threshing head under different working environments, such as environments with high or low humidity, to ensure a stable threshing effect.
