Description

Technical Field

[0001] This utility model relates to the field of agricultural and grain machinery technology, specifically a dual-channel angle-adjustable grain unloader. Background Technology

[0002] A grain unloader is an agricultural machine mainly used for collecting, loading, and unloading bulk grain in grain warehouses. When used in conjunction with a conveyor, it can also be used for stacking and loading grain onto trucks. The grain unloader can move bulk grain within a 180-degree range and is an indispensable part of grain harvesting and loading. The grain unloader is a powerful and easy-to-operate agricultural machine that plays an important role in grain harvesting and loading operations. Currently, the most commonly used grain unloader is the scraper type. The working principle of the scraper type grain unloader is that the electric motor drives the drive shaft through chain transmission, and then the unloading belt drives the unloading plate to scoop the bulk grain from the grain pile or the ground into the conveyor channel and transport it to a certain height. Finally, it can be directly unloaded onto the conveyor belt and transported to the predetermined location.

[0003] Currently, grain unloaders typically use only one unloading trough to unload grain from the ground. However, these unloaders cannot effectively gather the grain, and when unloading piles of grain, there may be side leakage or missed unloading. This means that the drying yard or storage silo still needs to be cleaned manually after the unloader has finished, which greatly increases labor costs. Utility Model Content

[0004] To address the problem of side leakage or missed removal that easily occurs in single-trough grain unloaders mentioned in the background art, the purpose of this utility model is to provide a dual-channel angle adjustable grain unloader.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-channel angle-adjustable grain unloader, comprising a tracked chassis and two grain unloading structures, the two grain unloading structures being arranged at an included angle, each grain unloading structure including a movable chassis, a conveying channel connected to the movable chassis via a bracket, a grain unloading trough being fitted at one end of the conveying channel, the two grain unloading troughs being hinged together via a hinge seat, a diverter plate being provided between the two grain unloading troughs, a driver's cab being provided on the tracked chassis, the tracked chassis being hinged to the corresponding movable chassis via a hydraulic support cylinder, and the hinge seat being connected to the tracked chassis via a connecting rod.

[0006] Preferably, the grain-removing trough is provided with a rotating shaft, and a drive motor is provided on one side of the grain-removing trough. The drive motor is connected to the rotating shaft via a corresponding belt and pulley. The conveying channel is provided with a grain-removing shaft and a grain-removing belt. The grain-removing belt is installed on the rotating shaft and the grain-removing shaft, and several grain-removing plates are installed on the grain-removing belt.

[0007] Preferably, two oppositely arranged gathering spiral plates are installed on the rotating shaft, and the two gathering spiral plates are symmetrically installed on both sides of the grain-pulling belt.

[0008] Preferably, the conveying channel is inclined.

[0009] Preferably, the diverter plate is made of soft rubber.

[0010] Preferably, a collection bin is provided on one side of the tracked chassis, and the output port of the conveying channel is connected to the collection bin via a connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model has two grain-digging structures arranged at an angle, which allows the grain to be uniformly gathered during use, effectively preventing grain leakage and greatly improving the grain-digging effect. This utility model is particularly suitable for grain pile digging operations. The two grain-digging mechanisms can effectively wrap the grain pile, and by digging the grain simultaneously with the two mechanisms, it can effectively prevent grain leakage or missed digging, further improving the efficiency of the operation.

[0013] 2. When this utility model is in use, the included angle between the two grain-digging structures can be controlled by a hydraulic support cylinder, thereby adapting to sites and grain piles of different widths and further improving its applicability. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] like Figures 1-4 As shown in the figure, this embodiment provides a dual-channel angle adjustable grain unloader, including a tracked chassis 101 and two grain unloading structures 200. The two grain unloading structures 200 are set at an angle. Each grain unloading structure 200 includes a movable chassis 201. A conveying channel 202 is connected to the movable chassis 201 via a bracket. The conveying channel 202 is inclined. A grain unloading trough 203 is installed at one end of the conveying channel 202. A rotating shaft is provided in the grain unloading trough 203. A drive motor 206 is provided on one side of the grain unloading trough 203. The drive motor 206 drives the rotating shaft via a corresponding belt and pulley. A grain unloading shaft is provided in the conveying channel 202. A grain unloading belt is provided in the conveying channel 202. The grain unloading belt is installed on the rotating shaft and the grain unloading shaft. A plurality of grain unloading plates 205 are installed on the grain unloading belt. Two oppositely arranged gathering spiral plates 204 are installed on the rotating shaft. The two gathering spiral plates 204 are symmetrically installed on both sides of the grain unloading belt.

[0022] In this embodiment, the converging spiral plate 204 can better gather the grain on both sides of the grain-retrieving plate 205, preventing any missed grains. Furthermore, the support bracket for the conveying channel 202 is an adjustable bracket. (Refer to...) Figure 4 The support is divided into a support bracket and an adjustable bracket. The support bracket is hinged to the conveying channel 202. The adjustable bracket is used to lift the grain trough 203 when it is not in use to prevent it from colliding with other debris on the ground. In this embodiment, the adjustable support adopts a hydraulic cylinder. There are also some brackets used for support that are conventional existing technologies, which are not shown in the figure of this embodiment.

[0023] The two grain troughs 203 are hinged together by hinge seat 208, see reference. Figure 3 A diversion plate 207 is provided between the two grain troughs 203. The diversion plate 207 is made of soft rubber.

[0024] Specifically, the lower end of the soft rubber diversion plate 207 is equipped with steel bristles to prevent grain from leaking out from below. The soft rubber diversion plate 207 can also effectively adapt to the two grain-digging structures 200 with variable angles to prevent gaps from forming between them and causing grain to be missed.

[0025] The tracked chassis 101 is equipped with a driver's cab 102. The tracked chassis 101 is connected by a corresponding hydraulic support cylinder 104. One end of the hydraulic support cylinder 104 is hinged to the mobile chassis 201, and the other end is hinged to the tracked chassis 101. The hinge seat 208 is connected to the tracked chassis 101 by a connecting rod 103. A collection bin 105 is provided on one side of the tracked chassis 101. The output port of the conveying channel 202 is connected to the collection bin 105 through a connecting pipe 106.

[0026] In this embodiment, refer to Figure 5 When performing grain removal operations on the grain pile, the angle between the two grain removal structures 200 can be adjusted by the hydraulic support cylinder 104 so that it can fully adapt to the grain pile. The connecting pipe 106 is a soft pipe that can transport the grain discharged from the outlet of the conveying channel 202 to the collection bin 105. In this embodiment, the collection bin 105 can be connected to a grain suction machine or a screw conveyor to facilitate moving the grain to a predetermined position.

[0027] It should be noted that this utility model has two grain-removing structures 200, which are set at an angle. This allows the grain to be uniformly gathered during operation, effectively preventing grain leakage and greatly improving the grain-removing effect. Furthermore, this utility model is extremely suitable for grain pile removal operations. The two grain-removing mechanisms can effectively enclose the grain pile, and by removing grain simultaneously, side leakage or missed removal is effectively prevented, further improving operational efficiency. During use, the angle between the two grain-removing structures 200 can be controlled by the hydraulic support cylinder 104, thus adapting to different widths of fields and grain piles, further enhancing its applicability.
