Description

Technical Field

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

[0002] Corn threshing is a crucial step in corn planting and processing. Mechanized threshing (such as corn threshers) can improve the efficiency of agricultural production. Corn threshers are core mechanical equipment used in agricultural production to separate corn kernels from ears. They achieve threshing through mechanical impact, squeezing, or rubbing, replacing traditional manual threshing, improving work efficiency, and reducing labor intensity.

[0003] Large corn threshers have a high discharge port, making them suitable for large transport vehicles. When receiving corn at the discharge port, the corn kernels tend to accumulate in a fixed position inside the truck's cargo box due to the fixed discharge location. This can cause the corn kernels to overflow from the cargo box, requiring workers to distribute the accumulated kernels evenly. Furthermore, the high discharge port can cause corn kernels to splash from the discharge port onto the outside of the cargo box, making them difficult to collect. Utility Model Content

[0004] This utility model provides a combined corn thresher that solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides a combined corn thresher, comprising: The threshing machine body has a conveyor belt fixedly installed on its surface, and a grain discharge column is provided on one side of the threshing machine body. A grain discharging device is disposed on the surface of a grain discharging column. The grain discharging device includes a rotating grain cylinder rotatably connected to the discharge end of the grain discharging column. A grain discharging cylinder is fixedly connected to the surface of the rotating grain cylinder, and the grain discharging cylinder is connected to the rotating grain cylinder.

[0006] Furthermore, the grain discharging device also includes a sleeve, which is slidably connected to the grain discharging cylinder. The sleeve is located on the inner wall of the grain discharging cylinder, and one end of the sleeve is fixedly connected to a conical cylinder.

[0007] Furthermore, an arc-shaped bracket a is fixedly connected to the surface of the sleeve, and a cylinder is fixedly connected to the surface of the grain discharge cylinder, with the output end of the cylinder fixedly connected to the arc-shaped bracket a.

[0008] Furthermore, the discharge end of the grain discharge column is connected to a grain discharge pipe, a gear ring is fixedly connected to the surface of the grain discharge pipe, a servo motor is fixedly connected to the surface of the rotating grain cylinder, and a pinion is fixedly connected to the output end of the servo motor, the pinion meshing with the gear ring.

[0009] Furthermore, an arc-shaped bracket b is fixedly connected to the surface of the grain dispensing cylinder, and two guide rods are fixedly connected to the surface of the arc-shaped bracket a, with the guide rods slidably connected to the arc-shaped bracket b.

[0010] Furthermore, a limit block is fixedly connected to one end of the guide rod.

[0011] Furthermore, a baffle is fixedly connected to the surface of the pinion.

[0012] The above-described solution of this utility model has at least the following beneficial effects: This invention, by setting up a rotating grain cylinder, a grain discharge cylinder, and a servo motor for driving the grain discharge device, changes the direction of the grain discharge cylinder by rotating the grain cylinder, thereby avoiding a large amount of corn kernels accumulating in the same position in the vehicle's cargo box and reducing the amount of work that workers need to do to evenly distribute the grain in the vehicle's cargo box.

Detailed Implementation

[0016] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0017] like Figures 1 to 4 As shown, an embodiment of this utility model provides a combined corn thresher, including: a thresher body 1, a conveyor belt 2 fixedly installed on the surface of the thresher body 1, and a grain discharge column 3 connected to one side of the surface of the thresher body 1; a grain discharge device 4, which is disposed on the surface of the grain discharge column 3, and includes a rotating grain cylinder 401 rotatably connected to the discharge end of the grain discharge column 3, and a grain discharge cylinder 402 fixedly connected to the surface of the rotating grain cylinder 401, and the grain discharge cylinder 402 communicating with the rotating grain cylinder 401.

[0018] like Figure 1 As shown, the threshing machine body 1 has a conveyor belt 2 fixedly installed on its surface. A grain discharge column 3 is connected to one side of the threshing machine body 1. During grain production operations, when processing mature corn, workers unload corn cobs from the vehicle into a grain storage tank. The truck then moves to the bottom of the grain discharge column 3. The conveyor belt 2 extends to the bottom of the grain storage tank. The threshing machine body 1 is then started, and the conveyor belt 2 transports the corn cobs from the grain storage tank to the threshing machine. After being impacted and peeled by the stirring rollers in the threshing machine, the corn kernels are screened by the screen and enter the grain discharge column 3. The corn kernels are then conveyed out from the grain discharge column 3 and fall into the cargo box of the vehicle.

[0019] like Figures 2 to 3 As shown, the grain dispensing device 4 is installed on the surface of the grain dispensing column 3. The grain dispensing device 4 includes a rotating grain cylinder 401 rotatably connected to the discharge end of the grain dispensing column 3. A grain dispensing cylinder 402 is fixedly connected to the surface of the rotating grain cylinder 401. The grain dispensing cylinder 402 is connected to the rotating grain cylinder 401. After a long period of grain dispensing, the corn kernels accumulate in the same position in the cargo box of the vehicle for a long time. The accumulated corn kernels are about to reach the critical height of the cargo box. Then, the controller controls the servo motor 409 to run, which drives the grain cylinder to rotate. The position of the grain dispensing cylinder 402 changes, thereby changing the accumulation position of the corn kernels to be conveyed later. This prevents the output corn kernels from accumulating in the same position in the cargo box, reducing the workload of the workers who distribute the corn in the cargo box.

[0020] like Figures 3 to 4As shown, the grain dispensing device 4 also includes a sleeve 403, which is slidably connected to the grain dispensing cylinder 402. The sleeve 403 is located on the inner wall of the grain dispensing cylinder 402. One end of the sleeve 403 is fixedly connected to a conical cylinder 4031. An arc bracket a405 is fixedly connected to the surface of the sleeve 403. A cylinder 404 is fixedly connected to the surface of the grain dispensing cylinder 402. The cylinder 404 is a QGB aluminum alloy cylinder produced by Ningbo Fenghua Zhongzhi Pneumatic Co., Ltd. The output end of the cylinder 404 is fixedly connected to the arc bracket a405. When dispensing corn kernels, the controller controls the operation of the cylinder 404. As the cylinder 404 operates, the sleeve 403 falls, so that the conical cylinder 4031 at the bottom of the sleeve 403 is close to the bottom of the vehicle cargo box, thereby preventing the splashed corn kernels from splashing outside the vehicle cargo box and thus avoiding grain waste.

[0021] like Figures 2 to 3 As shown, the discharge end of the grain discharge column 3 is connected to a grain discharge pipe, and a gear ring 411 is fixedly connected to the surface of the grain discharge pipe. A servo motor 409 is fixedly connected to the surface of the rotating grain cylinder 401. The servo motor 409 is a Panasonic MHMF042L1V2M 400W brakeable servo motor. A pinion 410 is fixedly connected to the output end of the servo motor 409. The pinion 410 meshes with the gear ring 411. The controller then controls the servo motor 409 to run, driving the pinion 410 to rotate. The pinion 410 meshes with the gear ring 411, causing the rotating grain cylinder 401 to rotate. As the rotating grain cylinder 401 rotates, the position of the grain discharge cylinder 402 changes, thus changing the accumulation position of the subsequently conveyed corn kernels.

[0022] like Figure 4 As shown, an arc-shaped bracket b406 is fixedly connected to the surface of the grain discharge cylinder 402. Two guide rods 407 are fixedly connected to the surface of the arc-shaped bracket a405. The guide rods 407 are slidably connected to the arc-shaped bracket b406. The guide rods 407 can provide peripheral support for the falling sleeve 403, so as to avoid the output end of the cylinder 404 from being overloaded by the lateral force, which would cause the cylinder 404 to be damaged.

[0023] like Figure 4 As shown, one end of the guide rod 407 is fixedly connected to a limit block 408, which can limit the maximum path of the sleeve 403 falling, thereby preventing the sleeve 403 from detaching from the inner wall of the grain cylinder 402.

[0024] like Figure 4 As shown, a baffle is fixedly connected to the surface of the pinion 410. The meshing point between the pinion 410 and the gear ring 411 is blocked by the baffles on the upper and lower sides, so that the meshing between the pinion 410 and the gear ring 411 is stable, resulting in stable transmission.

[0025] In this embodiment of the utility model, the thresher body 1 is a gravity screen type corn thresher produced by Huaxian Yudu Machinery Co., Ltd. Since the structure and operating principle of this type of thresher are existing technologies, its structure and operating principle need not be described in detail here.

[0026] Working principle: During grain production operations, when threshing mature corn, workers unload corn cobs from the vehicle into the grain storage tank. The truck then moves to the bottom of the grain discharge column 3. The conveyor belt 2 extends to the bottom of the grain storage tank. The threshing machine body 1 is then started, and the conveyor belt 2 transports the corn cobs from the grain storage tank to the threshing machine. After being impacted and peeled by the stirring rollers in the threshing machine, the corn kernels are screened by the screen and enter the grain discharge column 3. The corn kernels are then conveyed out from the grain discharge column 3 and fall into the cargo box of the vehicle.

[0027] After a long period of feeding, the corn kernels accumulate in the same position in the vehicle's cargo box, almost reaching the critical height of the cargo box. Subsequently, the controller controls the servo motor 409 to run, which drives the pinion 410 to rotate. The pinion 410 meshes with the gear ring 411, causing the rotating grain cylinder 401 to rotate. As the rotating grain cylinder 401 rotates, the position of the feeding cylinder 402 changes, altering the accumulation position of the subsequently conveyed corn kernels. This prevents the output corn kernels from accumulating in the same position in the vehicle's cargo box, reducing the workload of the workers distributing the corn in the cargo box.

[0028] When the corn kernels are being output, the controller controls the operation of cylinder 404. As cylinder 404 operates, sleeve 403 falls, causing the conical cylinder 4031 at the bottom of sleeve 403 to approach the bottom of the vehicle's cargo box. This prevents the flying corn kernels from splashing outside the vehicle's cargo box, thus avoiding food waste.

[0029] During operation, the equipment is relatively simple to control. The servo motor 409 can only control forward and reverse output, thereby controlling the rotating grain drum 401 to rotate to both sides. The cylinder 404 can only control pushing and retracting, thereby adjusting the extension length of the sleeve 403. After the cylinder 404 and the servo motor 409 stop running, they will self-lock to prevent automatic rotation and operation. Although these devices operate with simple electrical control, timely maintenance and repair are required to ensure that the equipment can operate stably for a long time.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
