Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery technology, and more specifically, to a discharge device for agricultural machinery. Background Technology
[0002] Agricultural machinery such as threshers, crushers, and chaff cutters need to discharge the materials obtained after threshing and crushing. Existing discharge methods include direct discharge from the discharge port and discharge through fan blades. However, the discharge distance of these two traditional discharge methods is relatively limited, and the discharge direction of the material cannot be adjusted when the agricultural machinery is working, which easily leads to the problem of material accumulation.
[0003] The prior art publication (announcement) document with the number CN222410226U provides a discharge device for agricultural machinery. In the related technology of this device, the direction of the discharge pipe can be adjusted to prevent the cob and kernels from accumulating together; the clamping plate can make the device more securely fixed on the corn thresher; the kernels mixed between the cob can also be discharged through the discharge hole, reducing the mixing of kernels and cob.
[0004] Although the existing technical solutions mentioned above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: when the motor drives the discharge pipe to perform rotating discharge operation, the discharged cob piles up in a ring shape, which obstructs the movement path of the corn thresher and is not conducive to the movement operation of the corn thresher equipment.
[0005] In view of this, we propose a material discharge device for agricultural machinery. Utility Model Content
[0006] To address the problems mentioned in the background art, this application provides a material discharge device for agricultural machinery.
[0007] The agricultural machinery discharge device provided in this application adopts the following technical solution:
[0008] A material discharge device for agricultural machinery includes a hopper with a clamping plate structure. One end of the hopper is rotatably connected to a screening cylinder with an inclined structure. A double-grooved gear disk is fixedly connected to the outside of the screening cylinder. A half-face gear is meshed and driven on one side of the double-grooved gear disk. A drive motor is fixedly connected to the middle of the half-face gear. The drive motor is fixedly connected to one side of the hopper.
[0009] By adopting the above technical solution, when the drive motor drives the half-face gear to rotate in one direction, the half-face gear meshes with the double-grooved gear disk, driving the double-grooved gear disk to drive the fixed screening cylinder to swing back and forth, so that the screening cylinder is semi-enclosed for material discharge, providing an open path for equipment displacement.
[0010] As an optional solution to the technical solution of this application, a lead wire ring is fixedly connected to one side of the hopper, and a steel rope is inserted through the outside of the lead wire ring. One end of the steel rope is fixedly connected to the hopper, and the other end is fixedly connected to an extension cylinder. The extension cylinder is fitted and slidably adapted to the outside of the screening cylinder.
[0011] By adopting the above technical solution, when the screening cylinder swings back and forth, the extension cylinder slidably connected at one end can automatically extend and adjust under the tension adjustment of the steel rope, so that the material discharged from the extension cylinder can accumulate over a wider range.
[0012] As an optional solution to the technical solution of this application, a spring is provided on one side of the extended material cylinder, the spring is sleeved on the outside of the screening material cylinder, and an abutment ring is provided on the other end of the spring, the abutment ring being fixedly connected to the outside of the screening material cylinder.
[0013] By adopting the above technical solution, the spring component can elastically abut and limit the extension cylinder, making the extension adjustment of the steel rope pulling the extension cylinder more stable.
[0014] As an optional solution to the technical solution of this application, a shaking filter plate is hinged to one end of the screening cylinder, and a ball sleeve is fixedly connected to one end of the shaking filter plate through the screening cylinder. A friction ball is rotatably connected inside the ball sleeve, and a wave ring is rolled and rubbed against one side of the friction ball. The wave ring is fixedly connected to the bottom of the hopper.
[0015] By adopting the above technical solution, when the screening cylinder is used for oscillating discharge, the internally hinged shaking filter plate can achieve oscillation under the rolling action of friction balls and wave rings, thereby pre-scattering the material discharged from the hopper and ensuring the screening cylinder's effect of classifying particles and rods.
[0016] As an optional solution to the technical solution in this application, a rubber gasket ring is added between the wave ring and the hopper.
[0017] By adopting the above technical solution, the rubber pad ring can reduce the amplitude generated by the rolling between the friction ball and the wave ring, ensuring the stability of the connection between the wave ring and the hopper.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. In this application, when the drive motor drives the half-face gear to rotate in one direction, the half-face gear meshes with the double-grooved gear disk, driving the double-grooved gear disk to drive the fixed screening cylinder to oscillate back and forth, so that the screening cylinder discharges material in a semi-enclosed manner, providing an open path for equipment displacement.
[0020] 2. This application utilizes the fact that when the screening cylinder oscillates back and forth, the extension cylinder slidably connected to one end can automatically extend and adjust under the tension adjustment of the steel rope, so that the material discharged from the extension cylinder can accumulate over a wider range.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.
[0027] Reference Figure 1 and Figure 2 The present application describes a discharge device for agricultural machinery, which includes a hopper 1 with a clamping plate structure. One end of the hopper 1 is rotatably connected to a screening cylinder 2 with an inclined structure. A double-grooved gear disk 3 is fixedly connected to the outside of the screening cylinder 2. A half-face gear 4 is meshed and driven on one side of the double-grooved gear disk 3. A drive motor 5 is fixedly connected to the middle of the half-face gear 4. The drive motor 5 is fixedly connected to one side of the hopper 1.
[0028] When the half-face gear 4 is driven to rotate in one direction by the drive motor 5, the half-face gear 4 meshes with the double grooved gear disk 3, driving the double grooved gear disk 3 to drive the fixed screening cylinder 2 to swing back and forth, so that the screening cylinder 2 discharges material in a semi-enclosed manner, providing an open path for the equipment to move.
[0029] Reference Figure 3 and Figure 1In the agricultural machinery discharge device described in this application embodiment, a lead wire ring 11 is fixedly connected to one side of the hopper 1. A steel rope 12 is inserted through the outside of the lead wire ring 11. One end of the steel rope 12 is fixedly connected to the hopper 1, and the other end is fixedly connected to an extension cylinder 13. The extension cylinder 13 is fitted and slidably adapted to the outside of the screening cylinder 2. A spring member 14 is provided on one side of the extension cylinder 13. The spring member 14 is fitted to the outside of the screening cylinder 2, and an abutment ring 15 is provided at the other end of the spring member 14. The abutment ring 15 is fixedly connected to the outside of the screening cylinder 2.
[0030] This agricultural machinery discharge device utilizes the reciprocating swing of the screening cylinder 2. The extension cylinder 13, which is slidably connected to one end, can automatically extend and adjust under the tension adjustment of the steel rope 12, so that the material discharged by the extension cylinder 13 can accumulate over a wider range. The spring component 14 can elastically abut and limit the extension cylinder 13, making the extension adjustment of the steel rope 12 pulling the extension cylinder 13 more stable.
[0031] Reference Figure 4 and Figure 2 In the agricultural machinery discharge device described in this application embodiment, a shaking filter plate 21 is hinged to one end of the screening cylinder 2. One end of the shaking filter plate 21 passes through the screening cylinder 2 and is fixedly connected to a ball sleeve 22. A friction ball 23 is rotatably connected inside the ball sleeve 22. A wave ring 24 is rolled and rubbed against one side of the friction ball 23. The wave ring 24 is fixedly connected to the bottom of the hopper 1, and a rubber pad ring is added between the wave ring 24 and the hopper 1.
[0032] When the material discharge device for agricultural machinery uses the oscillating discharge of the screening cylinder 2, the internally hinged vibrating filter plate 21 can achieve oscillation under the rolling action of the friction ball 23 and the wave ring 24, thereby pre-scattering the material discharged from the hopper 1 and ensuring the particle classification effect of the screening cylinder 2. The rubber pad ring can reduce the amplitude generated by the rolling between the friction ball 23 and the wave ring 24, and ensure the stability of the connection between the wave ring 24 and the hopper 1.
[0033] Working principle: When the hopper 1 is connected and fixed to the discharge end of the threshing machine, the material discharged by the threshing machine falls into the hopper 1. At this time, the working drive motor 5 drives the half-face gear 4 and the double groove gear disk 3 to mesh and drive, so that the meshing double groove gear disk 3 drives the screen cylinder 2 connected and fixed to swing back and forth for half a cycle.
[0034] During the oscillation of the screening cylinder 2, the internally hinged shaking filter plate 21 makes rolling friction contact with the fixedly installed wave ring 24 under the action of the friction ball 23, and oscillates and breaks up the material in the lower section.
[0035] After being filtered by the screening cylinder 2, the dispersed material is discharged and piled up under the guidance of the extended cylinder 13.
