Description

Technical Field

[0001] This utility model relates to a dustproof quantitative conveying mechanism for mixed feed. Background Technology

[0002] Premixed feed refers to a mixture of one or more additive ingredients and a carrier or diluent, also known as additive premix or premixed feed. Its purpose is to facilitate the uniform dispersion of trace amounts of raw materials in a large quantity of mixed feed. Since premixed feed ultimately needs to be mixed with regular feed, it is often made into pellets. However, due to the difficulty of making pellets in one go and the problem of uneven pellet size, it is necessary to first mix the premixed feed into strips, and then crush them into pellets.

[0003] In the premixed feed processing, the premixed feed, initially crushed into short strips, falls downwards via a belt conveyor to the input end of an elevator, and is then conveyed upwards by the elevator to a crusher. After being crushed, it enters a screening mechanism for screening, ultimately forming the finished product. In the existing technology, because the premixed feed on the belt conveyor is exposed and falls to the input end of the elevator, a large amount of dust is easily generated during the conveying process. Especially when the premixed feed falls downwards from the belt conveyor to the input end of the elevator, due to the height difference between the output end of the belt conveyor and the material elevator, a large amount of feed dust is also generated when the premixed feed falls. On the other hand, when the premixed feed is fed onto the belt conveyor, the thickness of the mixed feed on the belt conveyor varies due to different amounts of premixed feed being fed, resulting in inconsistent amounts of premixed feed output from the belt conveyor, affecting the efficiency of subsequent operations. Utility Model Content

[0004] This invention addresses the aforementioned problem by providing a dust-proof quantitative conveying mechanism for mixed feed, which is simple in structure and easy to use.

[0005] This utility model is constructed as follows: it includes a frame and a belt conveyor mechanism mounted on the frame. The belt conveyor mechanism is provided with a dust cover for enclosing it. The dust cover is provided with a material leveling component on the side near the discharge end of the belt conveyor mechanism. The dust cover is provided with a feeding channel at the input end of the belt conveyor mechanism and a discharge channel at the output end of the belt conveyor mechanism.

[0006] Furthermore, the material leveling assembly includes a mounting base and a leveling plate arranged sequentially from top to bottom. The mounting base is provided with a screw that can move up and down to cooperate with a threaded hole provided on the mounting base. The lower end of the screw passes through the dust cover and is connected to the leveling plate.

[0007] Furthermore, an elastic baffle is provided on the side of the paving plate near the input end of the belt conveyor mechanism. The elastic baffle is rotatably engaged with the paving plate, and a spring is provided between the elastic baffle and the paving plate to ensure that the elastic baffle is always bent upward.

[0008] Furthermore, guide rods are provided on both sides of the screw. The lower end of the guide rod is fixed to the flat plate, and the upper end of the guide rod passes through the guide hole provided on the dust cover and extends upward. The guide rod and the guide hole are slidably engaged.

[0009] Furthermore, the upper end of the screw is provided with a throttle handle, and the lower end of the screw is rotatably engaged with the flat plate.

[0010] Furthermore, a dust suction hood is installed in the discharge channel to suck out the generated dust.

[0011] Furthermore, a scraper is provided on the lower surface of the output end of the belt conveyor mechanism, and the scraper is fixed to the discharge channel by a positioning component.

[0012] Furthermore, the dust cover includes a left plate, a top plate, a front plate, a rear plate, a left bottom plate, a right upper inclined plate, a right vertical plate, a right lower inclined plate, a right rear plate, and a right front plate, and the discharge channel is composed of a right upper inclined plate, a right vertical plate, a right lower inclined plate, a right rear plate, and a right front plate.

[0013] Furthermore, the scraper is provided with an elongated hole, and the positioning member passes through the elongated hole and the fixing hole provided on the bottom surface of the discharge channel in sequence to fix the scraper to the discharge channel.

[0014] Furthermore, the positioning element is a bolt.

[0015] Compared with the prior art, this utility model has the following beneficial effects: The device has a simple structure and reasonable design. By feeding the premixed feed through the feeding channel of the dust cover, the premixed feed falls onto the belt conveyor and is then conveyed forward by the belt conveyor. When the premixed feed moves to the material leveling component, it is blocked by the elastic baffle and the leveling plate as the belt conveyor moves. After being leveled by the leveling plate, the thickness of the premixed feed output by the belt conveyor is basically the same. When the belt conveyor stops after traveling a certain distance, it can ensure that the amount of premixed feed entering the screw conveyor input end through the discharge channel is basically consistent, achieving a basic quantitative output and avoiding the impact on subsequent operation efficiency due to the inconsistent amount of premixed feed output by the belt conveyor. At the same time, the dust cover and the dust suction cover in the discharge channel can prevent dust generated during the conveying process from scattering to the outside, greatly reducing dust pollution.

Figure 6 This is a simplified schematic diagram illustrating the operation of an embodiment of this utility model. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Example: Figure 1-6As shown, a dustproof quantitative conveying mechanism for mixed feed is provided, including a frame 1 and a belt conveyor 2 mounted on the frame. The belt conveyor is a prior art technology. A dustproof cover 3 is provided on the outside of the belt conveyor to enclose it. A material leveling component 4 is provided inside the dustproof cover near the discharge end of the belt conveyor. The material leveling component is located above the upper belt of the belt conveyor. A feeding channel 301 is provided at the input end of the dustproof cover corresponding to the belt conveyor, and a discharge channel 302 is provided at the output end of the dustproof cover corresponding to the belt conveyor. The output end of the discharge channel is provided with a discharge port 303, which is directly opposite the input port of a screw conveyor 8. The screw conveyor is a prior art technology, which conveys the powder to the next process, such as crushing or screening.

[0019] During operation: The premixed feed is fed into the feed channel of the dust cover, falling onto the belt conveyor and continuing to be conveyed forward. When the premixed feed moves to the material leveling component, it is stopped by the elastic baffle and the leveling plate as the belt conveyor moves. After being leveled by the leveling plate, the thickness of the premixed feed output by the belt conveyor is basically the same. When the belt conveyor stops after traveling a certain distance, it ensures that the amount of premixed feed entering the screw conveyor input end through the discharge channel is basically consistent, achieving a basic quantitative output and avoiding the impact on subsequent operation efficiency due to inconsistent amounts of premixed feed output by the belt conveyor. At the same time, the dust cover and the dust suction hood in the discharge channel prevent dust generated during the conveying process from scattering to the outside, greatly reducing dust pollution.

[0020] In this embodiment of the utility model, the material leveling component 4 includes a mounting base 401 and a leveling plate 402 arranged sequentially from top to bottom. The mounting base is provided with a screw 403 that can move up and down to cooperate with a threaded hole provided on the mounting base. The lower end of the screw passes through the dust cover and is connected to the leveling plate.

[0021] Rotating the screw can move the paving plate up and down, thereby adjusting the distance between the paving plate and the belt conveyor mechanism, and thus adjusting the required output powder thickness, that is, the output thickness formed after the powder passes through the paving plate.

[0022] An elastic baffle 404 is provided on the side of the paving plate near the input end of the belt conveyor mechanism. The elastic baffle is rotatably engaged with the paving plate, and a spring 405 is provided between the elastic baffle and the paving plate. The spring is a coil spring and is set on the two rotating shafts of the elastic baffle. The two ends of the coil spring are fixed to the elastic baffle and the paving plate respectively. Under the action of the spring force, the elastic baffle is kept bent upward.

[0023] The upper part of the aforementioned elastic baffle contacts the dust cover, and the lower part is hinged to the flat plate via a pivot.

[0024] The elastic baffle and the spreading plate together limit the stacked powder. When the belt conveyor transports powder of varying thickness to the spreading plate, after passing through the spreading plate and being flattened by the spreading plate, the powder forms a uniform thickness and continues to be output outward. The elastic baffle plays a role in blocking the powder.

[0025] In this embodiment of the utility model, in order to improve the stability of adjusting the thickness of powder by lifting the spreading plate, guide rods 406 are provided on both sides of the screw. The lower end of the guide rod is fixed to the spreading plate, and the upper end of the guide rod passes through the guide hole provided on the dust cover and extends upward. The guide rod and the guide hole are slidably engaged.

[0028] In this embodiment of the utility model, a scraper 6 is provided on the lower surface of the output end of the belt conveyor mechanism. The scraper is fixed to the discharge channel by a positioning member 7. The scraper is in contact with the lower belt of the belt conveyor mechanism. The scraper is used to scrape off the residual material on the surface of the belt conveyor mechanism to reduce the problem of material residue.

[0029] In this embodiment of the utility model, in order to facilitate the adjustment of the scraper position, an elongated hole 601 is provided on the scraper, and the positioning member passes through the elongated hole and the fixing hole provided on the bottom surface of the discharge channel in sequence to fix the scraper to the discharge channel.

[0030] When the position of the scraper needs to be adjusted, loosen the positioning component, move the scraper along the length of the elongated hole, confirm the position, and then tighten the positioning component again to fix the scraper to the inner bottom surface of the discharge channel, that is, fix the scraper to the lower right inclined plate.

[0031] In this embodiment of the utility model, the positioning element is a bolt.
