Description

Technical Field

[0001] This utility model belongs to the field of screening machine technology, specifically relating to a feeding device for a screening machine. Background Technology

[0002] The main function of the feeding device is to transport materials to designated processing or handling equipment. Due to the different properties, shapes and sizes of different materials, different requirements are put forward for the design and use of the feeding device. Screening machines are increasingly widely used in material screening, grading and conveying. As a key component of the screening machine, the design and performance of the feeding device directly affect the overall operation of the screening machine. Traditional feeding devices may have problems such as uneven material distribution, easy clogging and severe wear. Therefore, improving and optimizing the feeding device has become an important way to improve the performance of the screening machine.

[0003] The feeding device of a current screening machine has the following disadvantages when in use: For example, with traditional hopper feeding, the material is prone to accumulating and clogging, which makes the screening machine unable to work continuously and stably, reducing screening efficiency. It may also lead to excessive local load on the screen and accelerated wear. Some simple feeding devices are difficult to adjust the feeding speed and flow rate as needed. Feeding too fast or too slow will affect the screening effect and production efficiency, and may also cause uneven distribution of material on the screen surface, reducing the screen utilization rate.

[0024] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0025] A feeding device for a screening machine includes,

[0026] The first support 1 has a storage shell 2 fixedly installed on its outer wall;

[0027] A conveying assembly is located on the inner wall of the storage shell 2. The conveying assembly includes a rotating rod 6, a protective shell 7, two second supports 8, two screw rods 9, a slide rail assembly 10, two third supports 11, a sliding plate 12, and the rotating rod 6. The rotating rod 6 is rotatably mounted on the top of the inner wall of the storage shell 2. Each second support 8 is fixedly mounted on the inner wall of the storage shell 2. The protective shell 7 is fixedly mounted between the outer walls of the two second supports 8. Each screw rod 9 is rotatably mounted on the bottom of the outer wall of the protective shell 7, and one end of each screw rod 9 extends into the interior of the protective shell 7. Each third support 11 is fixedly mounted on the outer wall of the first support 1. The slide rail assembly 10 is fixedly mounted between the outer walls of the two third supports 11. The sliding plate 12 is slidably mounted on the inner wall of the slide rail assembly 10.

[0028] In a specific embodiment of this utility model, uniform feeding through the conveying component ensures uniform material distribution on the screen surface, avoiding material accumulation or gaps. Uniformly distributed material can fully utilize the screen area, improving screening efficiency. Controlling the feeding speed and flow rate ensures that the material passes through the screen 5 at an appropriate speed. Appropriate material flow rate helps reduce the risk of clogging of the screen 5. First, the material is fed into the storage shell 2 from the feed inlet 3. The screen 5 can simply filter the material, allowing larger particles or impurities to pass through the screen for the first time. Then, the motor 4 drives the rotating rod 6 to rotate, thereby causing the drive gear 14 to drive the protective shell 7 and the driven gear 15 to rotate, which in turn causes the two screw rods 9 to rotate and start feeding. Uniform feeding can be achieved by the uniform rotation of the screw rods 9. While the rotating rod 6 rotates, the bottom can disperse the material to prevent it from gathering together. In addition, when not feeding, the bottom of the discharge port 13 can be sealed by sliding the sliding plate 12. The protective shell 7 can protect the drive gear 14 and the driven gear 15.

[0029] Specifically, the outer wall of the storage shell 2 is fixedly provided with a feed inlet 3, and the inner wall of the feed inlet 3 is embedded with a screen 5.

[0030] In a specific embodiment of this utility model, the outer wall of the storage shell 2 is fixedly provided with a feed inlet 3, and the inner wall of the feed inlet 3 is embedded with a screen 5, which facilitates feeding the material into the storage shell 2 and performing initial screening.

[0031] Specifically, a discharge port 13 is fixedly provided at the bottom of the outer wall of the storage shell 2.

[0032] In a specific embodiment of this utility model, a discharge port 13 is fixedly provided at the bottom of the outer wall of the storage shell 2 to facilitate the material to be sent out from the discharge port 13.

[0033] Specifically, each screw rod 9 has a driven gear 15 fitted on its outer wall, and the rotating rod 6 has a driving gear 14 fitted on its outer wall. The driving gear 14 meshes with the two driven gears 15.

[0034] In a specific embodiment of this utility model, the driving gear 14 meshes with two driven gears 15, which can ensure stable power transmission.

[0035] Specifically, a motor 4 is fixedly installed on the top of the outer wall of the storage shell 2.

[0036] In a specific embodiment of this utility model, a motor 4 is fixedly installed on the top of the outer wall of the storage shell 2, which achieves better power transmission.

[0037] Specifically, the output end of motor 4 is fixedly connected to the rotating rod 6.

[0038] In a specific embodiment of this utility model, the output end of the motor 4 is fixedly connected to the rotating rod 6, which enables the motor 4 to drive the rotating rod 6 to rotate stably and transmit power.

[0039] Working principle: First, the material is fed into the storage shell 2 through the feed inlet 3. The screen 5 can filter the material simply, allowing larger particles or impurities to pass through the screen for the first time. Then, the motor 4 runs and drives the rotating rod 6 to rotate, which in turn drives the driving gear 14 to rotate the protective shell 7 and the driven gear 15. This causes the two screw rods 9 to rotate and start feeding. The uniform rotation of the screw rods 9 can achieve uniform feeding. While the rotating rod 6 is rotating, the bottom can disperse the material to prevent it from gathering together. In addition, when not feeding, the bottom of the discharge port 13 can be sealed by sliding the sliding plate 12. The protective shell 7 can protect the driving gear 14 and the driven gear 15.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
