Description

Technical Field

[0001] This utility model relates to the field of corn processing technology, specifically to a corn threshing device. Background Technology

[0002] Corn threshing can be divided into three types depending on the processing volume and demand: traditional manual methods, small mechanical tools, and large-scale industrial processing. Inside the machine, there is a roller with toothed spikes and a roller wall full of concave holes. When working, the roller rotates at high speed, and the corn kernels are separated from the corn cob by impact and compression.

[0003] For example, patent application number 202410340165.7 published on the China Patent Network, entitled "Corn Threshing Device," includes a corn threshing machine. The front end of the corn threshing machine is fixedly equipped with a threshing rod grinding mechanism, which includes a synchronization mechanism. This invention allows for the grinding of threshing rods after threshing, thereby improving the equipment's functionality. Furthermore, when the corn content inside the corn bag reaches a specified percentage, the discharge port will be automatically sealed to prevent leakage of corn kernels when changing the corn bag. Through this technical solution, corn kernels can be changed without shutting down the equipment, preventing leakage.

[0004] However, existing threshers simply pile the corn cobs inside the machine after threshing, requiring users to frequently remove and unload them, which is time-consuming, labor-intensive, and affects operational efficiency.

[0005] Therefore, it is necessary to design and modify the corn threshing equipment. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a corn threshing device that facilitates material feeding. This solves the problem that in existing threshing machines, corn cobs are directly piled inside the equipment after threshing, requiring users to frequently remove and feed the corn cobs, which is time-consuming, labor-intensive, and affects operational efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corn threshing device, including a frame; The top of the frame is provided with a threshing cylinder. Supports are fixedly connected to both the front and back of the frame. The side of the support away from the frame extends to both sides of the threshing cylinder. A connecting rod is movably connected to the inner side of the support through a pin. The side of the connecting rod away from the support extends to the outer side of the threshing cylinder and is fixedly connected to the threshing cylinder. The threshing cylinder can swing and flip on the surface of the support through the connecting rod.

[0008] In a preferred embodiment of this utility model, the connecting rod extends through the side of the support to the outside of the support and is fixedly connected to a sleeve plate. A connecting frame is fixedly connected to the surface of the frame. A screw is movably connected to the inside of the connecting frame via a bearing. A transmission plate is threadedly connected to the surface of the screw. The transmission plate is located inside the sleeve plate. A sliding rod located inside the sleeve plate is fixedly connected to the surface of the transmission plate. The sliding rod is slidably connected to the sleeve plate.

[0009] In a preferred embodiment of this invention, the left end of the screw passes through the connecting frame and extends to the left side of the connecting frame, and a rotating wheel is fixedly connected to the left end of the screw.

[0010] As a preferred embodiment of this utility model, a screw sleeve is fixedly connected to the left side of the transmission plate, the screw sleeve is sleeved on the surface of the screw rod, and the screw sleeve and the screw rod are threadedly connected.

[0011] As a preferred embodiment of this utility model, a spring plate is fixedly connected to the surface of the sleeve plate, and the side of the spring plate away from the sleeve plate contacts the surface of the bracket, and the spring plate is elastic.

[0012] As a preferred embodiment of this utility model, a guide strip is fixedly connected inside the connecting frame, and the guide strip extends into the interior of the transmission plate on the side away from the connecting frame, and the transmission plate and the guide strip are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model transforms the traditional fixed structure of the threshing cylinder into a movable structure that can swing around the axis by setting a combination of bracket, pin and connecting rod. This directly realizes the flipping function of the threshing cylinder and provides a fundamental mechanical basis for subsequent automatic feeding. This fundamentally solves the core problem mentioned in the background technology that requires frequent corn cob removal and feeding operations, which is time-consuming and labor-intensive.

[0014] 2. This utility model converts rotary motion into linear motion through the threaded transmission of the screw and transmission plate, and then transmits the linear thrust to the threshing cylinder through the cooperation of the slide rod and the sleeve plate, so that it can be turned smoothly.

[0015] 3. This utility model greatly optimizes the human-computer interaction experience by incorporating a rotating wheel. The wheel provides a large lever arm, allowing the operator to drive the screw to rotate with less force, making operation more labor-saving and convenient.

[0016] 4. By setting a threaded sleeve, this utility model can increase the thread engagement distance and improve the stability of thread transmission.

[0017] 5. By setting up a spring plate, this utility model provides an additional stabilizing force for the threshing cylinder, preventing it from accidentally shaking or overturning due to vibration during operation, thus ensuring the stability and safety of the threshing process.

[0018] 6. This utility model strictly limits the movement path of the transmission plate by sliding the guide strip with the inside of the transmission plate, preventing it from deflecting or jamming during movement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a corn threshing device, including a frame 1; The top of the frame 1 is provided with a threshing cylinder 2. The front and back of the frame 1 are fixedly connected with brackets 3. The side of the bracket 3 away from the frame 1 extends to both sides of the threshing cylinder 2. The inner side of the bracket 3 is movably connected to a connecting rod 4 through a pin. The side of the connecting rod 4 away from the bracket 3 extends to the outer side of the threshing cylinder 2 and is fixedly connected to the threshing cylinder 2. The threshing cylinder 2 can swing and flip on the surface of the bracket 3 through the connecting rod 4.

[0023] refer to Figure 3 The connecting rod 4 extends through the side of the support 3 to the outside of the support 3 and is fixedly connected to the sleeve plate 5. The surface of the frame 1 is fixedly connected to the connecting frame 6. The inside of the connecting frame 6 is movably connected to the screw 7 through the bearing. The surface of the screw 7 is threadedly connected to the transmission plate 8. The transmission plate 8 is located inside the sleeve plate 5. The surface of the transmission plate 8 is fixedly connected to the slide rod 9 located inside the sleeve plate 5. The slide rod 9 is slidably connected to the sleeve plate 5.

[0024] As a technical optimization of this utility model, the rotational motion is converted into linear motion through the threaded transmission of the screw 7 and the transmission plate 8, and then the linear thrust is transmitted to the threshing cylinder 2 through the cooperation of the slide rod 9 and the sleeve plate 5, so that it can be turned over smoothly.

[0025] refer to Figure 3 The left end of the screw 7 passes through the connecting frame 6 and extends to the left side of the connecting frame 6. The left end of the screw 7 is fixedly connected to the rotating wheel 10.

[0026] As a technical optimization of this utility model, the addition of the rotating wheel 10 greatly enhances the human-computer interaction experience. The rotating wheel 10 provides a larger lever arm, allowing the operator to drive the screw 7 to rotate with less force, making operation more labor-saving and convenient.

[0027] refer to Figure 3 A screw sleeve 11 is fixedly connected to the left side of the transmission plate 8. The screw sleeve 11 is sleeved on the surface of the screw rod 7, and the screw sleeve 11 and the screw rod 7 are threaded together.

[0028] As a technical optimization of this utility model, by setting the screw sleeve 11, the thread engagement distance can be increased and the stability of the thread transmission can be improved.

[0029] refer to Figure 3 A spring plate 12 is fixedly connected to the surface of the sleeve plate 5. The side of the spring plate 12 away from the sleeve plate 5 is in contact with the surface of the bracket 3. The spring plate 12 is elastic.

[0030] As a technical optimization of this utility model, by setting the spring plate 12, an additional stabilizing force is provided to the threshing cylinder 2, preventing it from accidentally shaking or overturning due to vibration during operation, thus ensuring the stability and safety of the threshing process.

[0031] refer to Figure 3 A guide bar 13 is fixedly connected inside the connecting frame 6. The guide bar 13 extends into the interior of the transmission plate 8 from the side away from the connecting frame 6. The transmission plate 8 and the guide bar 13 are slidably connected.

[0032] As a technical optimization of this utility model, the sliding cooperation between the guide strip 13 and the inside of the transmission plate 8 strictly limits the movement path of the transmission plate 8, preventing it from deflecting or getting stuck during movement.

[0033] The working principle and usage process of this utility model are as follows: In the initial state, the threshing cylinder 2 is in a horizontal position for routine threshing operations. When threshing is complete and corn cobs need to be discharged, the operator rotates the rotating wheel 10, which drives the screw 7 to rotate. The rotational motion of the screw 7 is converted into the linear forward movement of the transmission plate 8 through threaded transmission. The sliding rod 9 on the transmission plate 8 then pushes the sleeve 5, which is fixedly connected to the threshing cylinder 2. Under this thrust, the entire threshing cylinder 2 flips upward around the pin on the support 3, causing the cylinder opening to tilt downward. The corn cobs accumulated inside then automatically slide down due to gravity, thus achieving easy and fast automatic feeding. After feeding is completed, the rotating wheel 10 is rotated in the opposite direction to make the transmission plate 8 retract. The threshing cylinder 2 then swings back under its own gravity, returning to a horizontal working state, ready for the next operation.

[0034] In summary, this corn threshing equipment, through the combination of support 3, pin shaft and connecting rod 4, transforms the threshing cylinder 2 from a traditional fixed structure to a movable structure that can swing around the axis, directly realizing the flipping function of the threshing cylinder 2. This provides a fundamental mechanical basis for subsequent automatic feeding, thereby fundamentally solving the core problem mentioned in the background technology that requires frequent corn cob removal and feeding operations, which is time-consuming and labor-intensive.
