Description

Technical Field

[0001] The invention belongs to the field of corn threshing, and in particular relates to a high-efficiency and low-loss corn threshing combined operation machine. Background Art

[0002] The corn field harvesting process includes three main steps: peeling, core breaking and threshing. The corn is usually threshed by a rice combine machine.

[0003] Patent application with announcement number CN113039943B discloses a high-efficiency and low-loss corn threshing combined machine. Paragraph 0039 of its specification discloses that a feeding hopper F19 is installed on the feeding port F12. Figure 5 and Figure 7 As shown, observation holes F15 are distributed at intervals on the surface of the upper cover F11 forming a door-shaped cross-section channel, and one end of an inclined pressure plate F16 is hingedly installed on the lower surface through a pin F13. The pin F13 is supported on the left and right side plates of the upper cover assembly F1, and a conical compression spring F17 with a small upper part and a large lower part is installed between the inclined pressure plate F16 and the upper cover F11. The specific assembly structure is that the upper end of the conical compression spring F17 is lifted and fixed to the lower surface of the upper cover F11 by means of a knob stud F18 and a tightening nut, and the lower end of the conical compression spring F17 is connected with the upper surface of the inclined pressure plate F16 away from the pin F13, thereby forming a downward pressure trend on the corn cobs.

[0004] However, in actual application, the corn raw materials need to be placed on the peeling mechanism through the feeding port through the feeding hopper for peeling and threshing. Because the feeding hopper needs to be set at an angle, it is convenient for the corn raw materials to slide into the peeling mechanism through the feeding port under the action of gravity for peeling and threshing. Therefore, a distance needs to be set between the feeding port and the ground. The staff needs to move the corn raw materials from the ground to the inside of the feeding hopper, and this process will increase the workload of the staff. At the same time, it will also reduce the efficiency of corn raw material threshing.

[0044] Working principle:

[0045] First, the second sliding plate 206 is driven, and the second sliding plate 206 drives the U-shaped plate 211 to slide in the direction away from the sliding column 203, and then the second sliding plate 206 is slid upward, and one side of the second sliding plate 206 slides out from one end of the discharge port 103, and then the corn raw material is placed on the upper side of the roller 213, and then the sliding column 203 is driven upward, and the sliding column 203 drives the U-shaped plate 211 to slide upward through the second sliding plate 206, and the U-shaped plate 211 drives the roller 213 to move upward through the U-shaped column 212, and the roller 213 drives the corn raw material to slide upward, and the U-shaped plate 211 drives the U-shaped column 212 to move to the upper side of the feeding hopper 102, and then the U-shaped column 212 is rotated, and the U-shaped column 212 drives the roller 213 to rotate, and the corn raw material slides into the interior of the thresher 101 through the feeding hopper 102 under the action of gravity for threshing, and the threshed corn raw material is discharged from the inside of the discharge port 103, thereby completing the threshing of the corn raw material.

[0046] The U-shaped column 212 is set so that the U-shaped column 212 drives the corn raw material to slide upward under the action of the U-shaped plate 211, and the corn raw material is driven to slide into the interior of the thresher 101 for threshing through the roller 213 set inside the U-shaped column 212. This process reduces the workload of the staff, improves the efficiency of threshing the corn raw material, and makes the process of threshing the corn raw material more convenient.

[0047] In order to make the sliding process of the sliding column 203 on the first support plate 200 more stable, the following structures are used to improve it. Figure 1-6As shown, the bottom of the frame 100 of this embodiment is fixedly fitted with two first support plates 200, a first guide groove 201 is provided on one side of the first support plate 200, a first servo motor is fixedly fitted inside the first guide groove 201, and a first threaded rod 202 is fixedly fitted at the output end of the first servo motor, one end of a sliding column 203 is slidably fitted inside the first guide groove 201, first threaded holes 204 are provided at both ends of the sliding column 203, and the first threaded holes 204 are threadedly fitted with the first threaded rod 202, a second guide groove 205 is provided on one side of the sliding column 203, a second sliding plate 206 is slidably fitted inside the second guide groove 205, and two first fixed blocks 207 are fixedly fitted on both sides of the second sliding plate 206, one side of one of the first fixed blocks 207 is fixedly fitted with a second servo motor, and a second threaded rod 209 is fixedly fitted at the output end of the second servo motor, a first through hole 208 is provided on one side of the first fixed block 207, and the second threaded rod 209 is fixedly fitted on the output end of the second servo motor. One end of the U-shaped plate 212 is rotatably engaged with the inside of the first through hole 208, two second threaded holes 210 are provided on one side of the sliding column 203, and the second threaded holes 210 are threadedly engaged with the second threaded rod 209, first T-shaped slots 215 are provided on both sides of the U-shaped column 212, and a first T-shaped block 216 is slidably engaged with the inside of the first T-shaped slot 215, and a second T-shaped slot 220 is provided on one side of the first T-shaped block 216, and second fixing blocks 218 are fixedly engaged with the two sides of the U-shaped plate 211, and the second fixing blocks 218 are fixedly engaged with the second fixing blocks 218.

A plurality of guide holes 222 are opened on the U-shaped column 212, and one end of the roller 213 is rotatably fitted inside the guide hole 222.

[0048] When the present embodiment is in use, the second servo motor is first started, and the output end of the second servo motor drives the second threaded rod 209 to rotate inside the first through hole 208. Since the second threaded rod 209 is threadedly engaged with the inside of the first support plate 200 through the second threaded hole 210, the second sliding plate 206 is inside the second guide groove 205 under the action of the second threaded rod 209. The second sliding plate 206 drives the U-shaped plate 211 to slide in the direction away from the sliding column 203. Then the staff puts the corn raw material on the upper side of the rotating roller 213, and then starts the first servo motor. The output end of the first servo motor drives the sliding column 203 to slide inside the first guide groove 201 through the first threaded rod 202. The sliding column 203 drives the U-shaped plate 211 to slide upward through the second sliding plate 206. The U-shaped plate 211 drives the roller 213 to slide upward through the U-shaped column 212, and the roller 213 drives the corn raw material to slide upward. When the U-shaped column 212 slides to the upper side of the feeding hopper 102, the electric push rod 219 is started, and the output end of the electric push rod 219 drives the first T-shaped rod 217 to slide upward.

The first T-shaped block 216 drives the U-shaped column 212 to rotate through the first T-shaped groove 215. The U-shaped column 212 drives the corn raw material to move through the roller 213. Under the action of gravity, the corn raw material slides into the interior of the thresher 101 through the feeding hopper 102, and the corn raw material is threshed by the thresher 101, and the threshed corn raw material is discharged through the discharge port 103.
