Description

Technical Field

[0001] The invention relates to the technical field of threshing, and in particular to a novel single-ear corn intelligent thresher. Background Art

[0002] Corn thresher refers to a mechanical device for threshing corn cobs. It is mainly composed of a drum, a concave plate, a sieve, a fan, a feeding hopper, a seed slide plate and a spiral guide rod. Corn cobs enter the drum through the feeding hopper and are threshed under the impact of the high-speed rotating drum and the interaction between corn cobs, the drum and the concave plate. Technical inspiration for thresher; Research on threshers revealed the following problems: After the thresher threshes the corn, a large number of corn cobs remain inside the thresher, so the thresher needs to be shut down regularly to clean the corn cobs inside the thresher, and then the thresher performs secondary threshing on the corn. Therefore, the thresher can only perform intermittent threshing on the corn, which makes it impossible for the thresher to assist the corn cobs to fall to the outside of the thresher during the threshing process, making it impossible for the thresher to perform continuous threshing on the corn. At present, CN202211120492.9 in the prior art discloses a corn thresher with an intelligent feeding shaft device, which includes a feeding auger, one end of which is provided with a first transmission device; a roller body in the threshing device, one end of which is provided with a second transmission device, and also includes a clutch transmission box, and both ends of the clutch transmission box are respectively linked with the first transmission device and the second transmission device; it also includes an intelligent tachometer for detecting the rotation speed of the roller body, and an electric push rod controlled by the output signal of the intelligent tachometer, the electric push rod pushes the clutch of the clutch transmission box to open and close, and further controls the rotation or stop of the first transmission device, and realizes controllable automatic load adjustment, reduces manual operation, and makes the corn thresher run more safely and smoothly. The structure improves the corn thresher according to the actual working conditions, has high practicality, and has market promotion value; The invention can mainly solve the problem that the thresher cannot assist corn ears to fall to the outside of the thresher during the threshing process. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a new type of single-ear corn intelligent thresher to solve the problems described in the above background technology.

[0004] The purpose and efficacy of a new type of single-ear corn intelligent thresher of the present invention are achieved by the following specific technical means: a new type of single-ear corn intelligent thresher, comprising a frame, a motor is provided on one side of the upper end of the frame, a roller is provided on the upper end of the frame, a main shaft is rotatably connected to the end of the motor close to the roller, a hopper passes through the upper end of the roller, a screen plate is provided at the lower end of the roller, and a side plate is provided at the end of the roller away from the motor.

[0005] Furthermore, the motor is connected to the power supply circuit through a power line, and the motor is a DC motor, which drives the main shaft to rotate inside the drum.

[0006] Furthermore, the drum as a whole is tilted downward by 5-25 degrees, and the hopper is located at the end of the drum that is tilted upward.

[0007] Furthermore, the hopper is located at one end of the drum that is inclined upward, and after the corn passes through the hopper and enters the interior of the drum, the corn can move downward toward one side of the side plate.

[0008] Furthermore, an opening is provided at the lower end of the side plate, and a slide groove is provided at one end of the side plate away from the drum, and the slide groove is arranged vertically.

[0009] Furthermore, the sieve plate is penetrated by holes with a diameter of 1-1.5 cm. The side of the sieve plate is arranged in an arc shape with an arc angle of 180°. The sieve plate is located on the side of the drum close to the side plate.

[0010] Furthermore, a mounting frame is provided on the outside of the main shaft, a retaining ring is distributed on the outside of the mounting frame, blades are rotatably sleeved on the outside of the mounting frame close to the retaining ring, rotating spheres are hinged on both sides of the blades, and a convex strip is swingably connected to one side of the rotating sphere.

[0011] Furthermore, the mounting frame passes through the outside of the main shaft, the clamping rings are evenly arranged on the outside of the mounting frame, the clamping rings are spaced 5-10 cm apart, and the blades are located between the clamping rings.

[0012] Furthermore, the blades are arranged on the outer side of the mounting frame in plurality, and when the main shaft drives the mounting frame to rotate, the blades rotate and move synchronously.

[0013] Furthermore, a rotating shaft is hinged at the upper end of the side panel opening, a baffle is swingably provided at the lower end of the rotating shaft, a curved ring is inlaid on the side of the baffle away from the roller, a slider is provided at the end of the curved ring close to the side panel slide groove, and the slider slides vertically inside the side panel slide groove.

[0014] Furthermore, the rotating shaft and the baffle plate swing in a vertical direction. When the baffle plate does not swing, the sliding block is at the lower end of the side plate sliding groove, and the baffle plate is in a vertical state as a whole.

[0015] Furthermore, the weight of the slider is 100-200 g greater than the weight of the baffle.

[0016] Furthermore, a bracket is installed on the side of the side plate close to the drum, and the lower end of the bracket is rotatably connected to a rotary bearing, and fan blades are distributed on the outer side of the rotary bearing.

[0017] Furthermore, the rotary bearings are arranged horizontally.

[0018] Furthermore, the fan blades penetrate through one side of the opening of the side panel, the fan blades are arranged in an arc shape, the fan blades surround the outer side of the rotating bearing, and the length of the fan blades is the same as the length of the opening of the side panel.

[0019] Furthermore, the arc-shaped arched part of the fan blade fits with the lower end of the inner wall of the drum, so that the fan blade pauses every time it rotates 90°.

[0020] Beneficial effects: 1. The main shaft drives the mounting frame to rotate as a whole, and the blades on the outside of the mounting frame rotate synchronously, and the blades move horizontally between the retaining rings, so that the blades can thresh the corn in the horizontal direction during the rotation process. Through the rotation and movement of multiple blades, the corn inside the drum can be threshed quickly, and the rotation direction of the main shaft and the mounting frame can be changed by adjusting the rotation direction of the motor, thereby changing the horizontal movement direction of the blades. Since the blades are between the retaining rings, the retaining rings can limit the horizontal movement direction of the blades; 2. After threshing, the corn cobs are accumulated on one side of the drum near the side plate, and the corn cobs are squeezed to one side of the baffle plate. The baffle plate is tilted and swung by the rotating shaft, and the corn cobs can fall to the outside of the drum through the opening of the side plate, so that the thresher can conveniently discharge the corn cobs during the threshing process, and then can form a continuous threshing process for the corn, avoiding the situation that the existing thresher needs to be shut down regularly to take out the corn cobs inside; 3. After the baffle plate swings upward, the baffle plate pulls the slider to slide upward through the curved ring, and the slider slides upward inside the slide groove of the side plate. Since the weight of the slider is 100-200g greater than the weight of the baffle plate, the slider can generate downward gravity on the baffle plate through the curved ring after sliding upward, and then the weight of the slider can assist the baffle plate to return to its original position through the rotating shaft, thereby preventing the corn kernels and corn ears from synchronously entering the opening of the side plate due to the baffle plate being continuously tilted upward; 4. After the corn cobs are piled up on one side of the drum, they are squeezed to one side of the fan blades. The fan blades rotate through the rotating bearings. The arc-shaped arch of the fan blades fits with the lower end of the inner wall of the drum, so that the fan blades pause every 90° rotation. Therefore, the fan blades can assist the corn cobs to move evenly to one side of the baffle, avoiding the situation where a large number of corn cobs are squeezed to one side of the baffle, resulting in the baffle being unable to swing downward through the drive of the slider. Then, through the rotation of the fan blades, the corn cobs can be diverted and discharged. BRIEF DESCRIPTION OF THE DRAWINGS

After the corn passes through the hopper 103 and enters the drum 102, the corn can move downward toward one side of the side plate 106. The lower end of the side plate 106 is provided with an opening, and the end of the side plate 106 away from the drum 102 is provided with a slide groove, which is arranged in a vertical shape. Figure 3 As shown; The lower end of the side plate 106 is provided with openings, which are arranged in a transverse direction, and the corn ears fall through the openings to the outside of the drum 102; The sieve plate 104 has holes running through it, the diameter of the holes is 1-1.5 cm, the side of the sieve plate 104 is arranged in an arc shape, the arc angle is 180°, and the sieve plate 104 is located on the side of the drum 102 close to the side plate 106; The corn enters the drum 102 through the hopper 103, and the motor 101 drives the main shaft 105 to rotate. Since the drum 102 is tilted downward by 5-25 degrees as a whole, the corn moves toward one side of the side plate 106 as a whole, and the main shaft 105 and the drum 102 can thresh the corn. The corn kernels fall to the bottom of the drum 102 through the holes in the sieve plate 104, and then the lower end of the side plate 106 is provided with an opening, which is arranged horizontally, and the corn cobs fall to the outside of the drum 102 through the opening. Example 2: Refer to the attached manual Figure 1-3 As can be seen from Figures 7 and 8, the difference between Example 2 and Example 1 is that a mounting frame 4 is provided on the outer side of the main shaft 105, a retaining ring 401 is distributed on the outer side of the mounting frame 4, and blades 402 are rotatably sleeved on the outer side of the mounting frame 4 close to the retaining ring 401, and rotating spheres 403 are hinged on both sides of the blades 402, and a convex strip 404 is swingably connected to one side of the rotating sphere 403; Wherein: the mounting frame 4 passes through the outer side of the main shaft 5, the clamping rings 401 are evenly arranged on the outer side of the mounting frame 4, the intervals between the clamping rings 401 are 5-10cm, and the blades 402 are between the clamping rings 401; The blades 402 are provided on the outer side of the mounting frame 4 in plurality. When the main shaft 105 drives the mounting frame 4 to rotate, the blades 402 rotate and move synchronously. Wherein: the main shaft 105 drives the mounting frame 4 to rotate as a whole, the outer blades 402 of the mounting frame 4 rotate synchronously, and the blades 402 move in the horizontal direction between the retaining rings 401, so that the blades 402 can thresh the corn in the horizontal direction during the rotation process, and the corn inside the drum 102 can be threshed quickly through the rotation and movement of multiple blades 402, and the rotation direction of the motor 101 can be changed to change the rotation direction of the main shaft 105 and the mounting frame 4, thereby changing the horizontal movement direction of the blades 402. Since the blades 402 are between the retaining rings 401, the retaining rings 401 can limit the horizontal movement direction of the blades 402; Example 3: Refer to the attached manual Figure 1-6 It can be known that the difference between Example 3 and Examples 1 and 2 is that the upper end of the opening of the side plate 106 is hinged with a rotating shaft 301, the lower end of the rotating shaft 301 is swung with a baffle 3, the side of the baffle 3 away from the drum 102 is inlaid with a curved ring 302, and the end of the curved ring 302 close to the sliding groove of the side plate 106 is provided with a slider 303, and the slider 303 slides in the sliding groove of the side plate 106 in a vertical direction; Wherein: the rotating shaft 301 and the baffle 3 swing in a vertical direction. When the baffle 3 does not swing, the slider 303 is at the lower end of the slide groove of the side plate 106. At this time, the baffle 3 is in a vertical state as a whole. Figure 4 As shown; The curved ring 302 is made of a deformable material, such as rubber; The weight of the slider 303 is 100-200 g greater than the weight of the baffle 3; Wherein: after threshing, the corn cobs are accumulated on one side of the drum 102 near the side plate 106, and the corn cobs are squeezed to one side of the baffle 3, and the baffle 3 is tilted and swung by the rotating shaft 301, and the corn cobs can fall to the outside of the drum 102 through the opening of the side plate 106, so that the thresher can conveniently discharge the corn cobs during the threshing process, and then can form a continuous threshing process for the corn, avoiding the situation that the existing thresher needs to be shut down regularly to take out the corn cobs inside; After the baffle 3 swings upward, the baffle 3 pulls the slider 303 to slide upward through the curved ring 302, and the slider 303 slides upward inside the slide groove of the side plate 106. Since the weight of the slider 303 is 100-200g greater than the weight of the baffle 3, the slider 303 can generate downward gravity on the baffle 3 through the curved ring 302 after sliding upward, and then the weight of the slider 303 can assist the baffle 3 to return to its original position through the rotating shaft 301, thereby preventing the corn kernels and corn ears from synchronously entering the opening of the side plate 106 due to the baffle 3 being continuously tilted upward. Example 4: Refer to the attached manual Figure 3-6It can be seen that the difference between Example 4 and Examples 1-3 is that a bracket 2 is installed on the side of the side plate 106 close to the drum 102, the lower end of the bracket 2 is rotatably connected to a rotary bearing 201, and fan blades 202 are distributed on the outer side of the rotary bearing 201; Wherein: the rotary bearing 201 is arranged in a transverse direction; The fan blade 202 passes through one side of the opening of the side plate 106. The fan blade 202 is arranged in an arc shape. The fan blade 202 surrounds the outer side of the rotating bearing 201. The length of the fan blade 202 is the same as the length of the opening of the side plate 106. The arc-shaped arch of the fan blade 202 fits with the lower end of the inner wall of the drum 102, so that the fan blade 202 pauses every time it rotates 90 degrees; Among them: after the corn ears are piled up on one side of the inside of the drum 102, the corn ears are squeezed to one side of the fan blade 202, and the fan blade 202 rotates through the rotating bearing 201. The arc-shaped arch of the fan blade 202 fits with the lower end of the inner wall of the drum 102, so that the fan blade 202 pauses every 90° rotation. Therefore, the fan blade 202 can assist the corn ears to move evenly to one side of the baffle 3, avoiding the situation that a large number of corn ears are squeezed to one side of the baffle 3, resulting in the baffle 3 being unable to swing downward by the slider 303, and then the rotation of the fan blade 202 can form a diversion discharge for the corn ears.
