Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, in particular to a feeding structure of a corn thresher. Background Art

[0002] In the process of modern agricultural mechanization, corn thresher is an important agricultural processing equipment, and its working efficiency directly affects the harvesting and processing efficiency of corn. However, corn threshers on the market currently have a common problem: the feeding port is designed to be high, which requires farmers to use additional feeding equipment to feed the material during operation, increasing the complexity and cost of operation.

[0003] What is more difficult is that due to the different shapes, sizes and irregular shapes of corn, it is easy to cause blocking and jamming during the feeding process. When this happens, the machine needs to be stopped for cleaning and maintenance, which not only seriously affects the continuous working performance of the thresher, but also greatly reduces the overall operating efficiency.

[0004] Therefore, there is a certain market demand for designing a corn thresher feeding structure that can effectively prevent blockage and jamming of materials. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a feeding structure of a corn thresher which can effectively prevent clogging and jamming of materials, so as to solve the above-mentioned problems.

[0006] The utility model discloses a feeding structure of a corn thresher, comprising a base, a conveying cylinder hingedly arranged on the base, a spiral conveying rod arranged in the conveying cylinder, a double-shaft motor arranged on the conveying cylinder, one output shaft of the double-shaft motor is drivingly connected to the spiral conveying rod, and an eccentric block is arranged on the other output shaft; a hopper is arranged on the top of the hinged end of the conveying cylinder, a soft connecting piece is arranged between the hopper and the conveying cylinder, the other end of the conveying cylinder is tilted upward and provided with a discharge port, a support rod is hingedly arranged on the base, the support rod is hinged to the conveying cylinder, the support rod is cut in the middle and is provided with a spring connection.

[0007] Furthermore, a telescopic mechanism is provided on the base, and a telescopic end of the telescopic mechanism is hinged to the support rod.

[0008] Furthermore, a sliding block is provided on the telescopic end of the telescopic mechanism, a sliding rail matched with the sliding block is provided on the base, and the support rod is hinged to the sliding block.

[0009] Preferably, the telescopic mechanism is a hydraulic telescopic rod.

[0010] Furthermore, casters are provided at the bottom of the base.

[0011] Furthermore, the discharge port is provided with a trumpet-shaped rubber guide sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. One axis of the dual-axis motor drives the spiral conveyor rod to ensure that the corn can be stably and continuously transported to the feeding port of the thresher. The eccentric block set on the other axis also has the function of a vibration motor. By generating vibration, it effectively avoids the blockage and jamming of corn during transportation, greatly improving work efficiency.

[0014] 2. With the function of angle adjustment, it can be adjusted according to the feeding port of corn thresher with different heights and angles, which enhances the versatility and adaptability of the system. This makes the same set of equipment applicable to different types of threshers, reducing the threshold and cost of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0019] The utility model discloses a feeding structure of a corn thresher, comprising a base 1, a conveying cylinder 2 is hingedly provided on the base 1, a spiral conveying rod 3 is provided in the conveying cylinder 2, a double-shaft motor 4 is provided on the conveying cylinder 2, one output shaft of the double-shaft motor 4 is drivingly connected to the spiral conveying rod 3, and an eccentric block 5 is provided on the other output shaft; a hopper 6 is provided on the top of the hinged end of the conveying cylinder 2, a soft connecting piece 7 is provided between the hopper 6 and the conveying cylinder 2, the other end of the conveying cylinder 2 is tilted upward and provided with a discharge port 8, a support rod 9 is hingedly provided on the base 1, the support rod 9 is hinged to the conveying cylinder 2, the support rod 9 is cut in the middle and is provided with a spring 10 for connection.

[0020] The preferred technical solution in this embodiment is that, considering that the height of the feed port of a corn thresher is different when the size of the corn thresher is different, in order to be able to adapt to various types of corn threshers, the angle of the conveying cylinder 2 is designed to be adjustable, as shown in the following example. Figure 1 As shown in , a telescopic mechanism 11 is provided on the base 1, and the telescopic end of the telescopic mechanism 11 is hinged to the support rod 9. By controlling the extension length of the telescopic end of the telescopic mechanism 11, the angle of the support rod 9 is adjusted, and the synchronous adjustment of the angle of the conveying cylinder 2 can be achieved.

[0021] The preferred technical solution in this embodiment takes into account that after the telescopic end of the telescopic mechanism 11 is hinged to the support rod 9, the telescopic end thereof will be suspended in the air and will be subjected to excessive radial force, thereby affecting the service life of the telescopic mechanism 11; a slider 12 is provided on the telescopic end of the telescopic mechanism 11, a slide rail 13 adapted to the slider 12 is provided on the base 1, and the support rod 9 is hinged to the slider 12.

[0022] The preferred technical solution in this embodiment is to ensure the overall support force of the support rod 9. Figure 1 As shown in , after the support rod 9 is cut from the middle, both ends thereof are divided into multiple support rods, and springs 10 are provided between the symmetrical support rods for connection.

[0023] In the preferred technical solution of this embodiment, the telescopic mechanism 11 is a hydraulic telescopic rod.

[0024] In the preferred technical solution of this embodiment, the soft connector 7 is a rubber joint (mature prior art).

[0025] In the preferred technical solution of this embodiment, casters 14 are provided at the bottom of the base 1 for easy movement.

[0026] The preferred technical solution in this embodiment is that the discharge port 8 is provided with a trumpet-shaped rubber guide sleeve 15, and the rubber guide sleeve 15 is elastic and can be sleeved on the feed port of the corn thresher and then locked using a clamp ring or a steel wire.

[0027] The usage and principle of the utility model are as follows: a number of manpower continuously add corn to the hopper 6, and continuously input corn into the hopper 6. Through the operation of the dual-axis motor 4, one of the output shafts is used to drive the spiral conveying rod 3, and the corn dropped into the conveying cylinder 2 from the hopper 6 is stably and continuously conveyed to the feeding port of the corn thresher; and the eccentric block 5 arranged on the other output shaft also has the function of a vibration motor, which drives the entire conveying cylinder 2 to vibrate by rotation. Since the hopper 6 and the conveying cylinder 2 are connected by a soft connector 7, the blocking and jamming of corn during the conveying process can be effectively avoided, greatly improving the work efficiency. When it is necessary to adjust the height of the discharge port 8, by controlling the extension length of the telescopic end of the telescopic mechanism 11, the angle of the support rod 9 is adjusted, so that the angle of the conveying cylinder 2 can be adjusted, and the height of the discharge port can be adjusted synchronously.
