[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] Example

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an auxiliary device for a coal mining robotic arm, including a coal mining machine 1, wherein a processing mechanism 2 and a water spraying mechanism 3 are provided on the body of the robotic arm of the coal mining machine 1;

[0023] The processing mechanism 2 includes a box 201 fixed to a robotic arm. Arc-shaped rods 202 are arranged in an array at an angle inside the box 201. A fixing plate 203 is fixedly connected to the inner surface of the box 201. The upper surface of the fixing plate 203 is fixedly connected to the lower surface of the screen 205 through a vibration motor 204. The arc-shaped rods 202 make it easier for coal blocks to slide off. The vibration motor 204 makes the screen 205 vibrate, which can prevent coal blocks from accumulating on the surface of the screen 205.

[0024] The water spraying mechanism 3 includes a water pump 301 fixed to the robotic arm and a nozzle 302 embedded on one side of the head of the coal mining machine 1. A water filter 303 is provided under the water pump 301. The nozzle 302 is connected to the water pump 301 through a pipe. The water pump 301 is connected to the water filter 303. At the same time, the water pump 301 is also connected to other water sources, which improves the efficiency of water resource utilization.

[0025] Specifically, the lower surface of the box 201 is provided with a discharge port 206, and the side of the box 201 is provided with a through hole 207. Coal pieces falling between the arc rods 202 will pass through the screen 205, and water will fall into the box 201 through the screen 205. The coal pieces will leak out through the discharge port 206. The through hole 207 on one side makes it convenient for workers to handle impurities in the box 201, and also facilitates the laying of pipes for connecting the water filter 303.

[0026] Specifically, a diversion plate 4 is fixedly installed on one side of the box 201. The diversion plate 4 is in the shape of an inverted V. A baffle 5 is fixedly connected to the other side of the diversion plate 4. The baffle 5 can allow coal blocks to slide off the diversion plate 4 on both sides of the box 201.

[0027] The working principle of this utility model is as follows:

[0028] During the crushing of the coal seam by the machine head, water can be sprayed through the water pump 301 and the nozzle 302. The water that cools and reduces dust in the machine head will fall into the housing 201. The coal blocks will slide down through the arc rod 202 and the diverter plate 4, while the water will flow into the housing 201 through the screen 205. The water will be filtered through the water filter 303 and then sprayed out again through the nozzle 302, which improves the utilization efficiency of water resources.

[0029] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
