Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing device technology, specifically to a bait crushing device. Background Technology
[0002] High-quality fish bait, through the scientific formulation of scent components and physical properties, can significantly enhance the fish-attracting effect and the probability of catching fish, thus having a decisive impact on the final catch quantity and the selective fishing of target fish species. In the production process of fish bait, crushing and processing is a crucial step. By finely crushing the raw materials, the particle size, mixing uniformity and solubility of the bait can be optimized, making it present a more natural atomization effect in the water, thereby improving its fish-attracting ability.
[0003] Existing technologies for crushing fish bait typically employ counter-rotating double-roller crushers. The opposing rotation of the two rollers achieves compression and shearing of the material. However, because the rotational forces of the two rollers cancel each other out in the lower center of the crushing drum, a crushing blind zone exists there. This causes larger fish bait particles to accumulate in the lower center of the crushing drum during crushing, reducing the crushing effect and affecting the quality of the fish bait. Therefore, we propose a bait crushing device to solve the above problems. Utility Model Content
[0004] The present invention aims to provide a bait crushing device to solve the problem that large bait particles will settle in the lower middle part of the crushing barrel during crushing, resulting in a reduction in the crushing effect of the bait.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bait crushing device, including a mounting frame, a crushing barrel at the upper end of the mounting frame, a filter screen at the lower end of the crushing barrel, a crushing component and a screening component inside the crushing barrel, the screening component including a rotating shaft, a power component and several mounting frames, the rotating shaft being located inside the crushing barrel, the power component being located on the outer wall of the crushing barrel and capable of driving the rotating shaft to rotate, several mounting frames being evenly arranged on the outer wall of the rotating shaft, each mounting frame having several screening steel plates on the inner wall of the side away from the rotating shaft, and the gap between each screening steel plate being equal to the maximum aperture of the filter screen, each screening steel plate having a semi-circular groove along the direction of rotation of the rotating shaft, and a brush being provided at the end of the mounting frame away from the rotating shaft, and the brush being able to abut against the filter screen.
[0006] The beneficial effects of this solution are as follows: The filter screen is used to filter the crushed bait. Bait particles smaller than the filter screen aperture leak out of the crushing barrel, while bait particles larger than the filter screen aperture are located at the top of the filter screen. By setting the gap between the screening steel plates to match the filter screen aperture, it is ensured that the crushed bait particles can only pass through the screening steel plates after reaching the target particle size, thus preventing substandard particles from being mixed into the finished product. Semi-circular grooves are opened on the screening steel plates to catch larger bait particles, so that the bait is thrown into the crushing zone along with the screening steel plates for further crushing. The brush at the end of the mounting frame is in close contact with the filter screen and continuously scrapes the surface of the filter screen during rotation, effectively preventing bait from adhering to or clogging the mesh, maintaining filtration efficiency. The rotating shaft drives the mounting frame and screening steel plates to rotate, causing substandard bait particles to be screened out by the screening steel plates and remain in the semi-circular groove. Then, under the action of centrifugal force, they are thrown back into the crushing zone for secondary crushing, forming a closed-loop process of "crushing-screening-re-crushing", which significantly improves the crushing uniformity and enhances the crushing effect of the fish bait.
[0007] Preferably, as an improvement, the crushing assembly includes a motor, a first driving wheel, a first driven wheel, a first belt, and two sets of crushing rollers. The motor is located at the upper end of the mounting frame, the first driving wheel is located at the output end of the motor, the two sets of crushing rollers are symmetrically arranged inside the crushing barrel, and the two sets of crushing rollers are located above the screening assembly. Each crushing roller has several crushing blades on its outer wall, and the crushing blades on the outer walls of the two sets of crushing rollers are staggered. Each set of crushing rollers has a gear at the end away from the motor, and the two gears mesh with each other. The first driven wheel is located at the end of one set of crushing rollers closer to the motor, and the first belt is located on the outer wall of the first driving wheel and the first driven wheel.
[0008] The beneficial effects are as follows: The crushing blades of the two sets of crushing rollers are arranged in an alternating manner, forming a dual force of shearing and extrusion when rotating in opposite directions, which greatly improves the crushing efficiency of the bait. Through the synchronous drive of meshing gears, it is ensured that the two sets of crushing rollers rotate at the same speed and in opposite directions, avoiding the problem of material accumulation or uneven crushing caused by the difference in speed. The two sets of crushing rollers are set above the screening component, so that the bait falls directly to the screening area after being crushed, and is naturally classified by gravity, so that the larger bait is located on the surface of the filter screen. Then, in conjunction with the screening component, the larger bait is re-crushed, improving the crushing effect of the fish bait.
[0009] Preferably, as an improvement, the power component includes a second driving wheel, a second driven wheel, and a second belt. The second driving wheel is located on the outer wall of one of the gears, the second driven wheel is located at the end of the shaft away from the motor, and the second belt is located on the outer walls of the second driving wheel and the second driven wheel.
[0010] Preferably, as an improvement, the inner wall of the crushing barrel is symmetrically provided with crushing platforms, and the upper part of each crushing platform is provided with several cutting blades that are offset from the crushing blades on the outer wall of the crushing roller.
[0011] The beneficial effects are as follows: by adding a crushing platform to the inner wall of the crushing barrel, the crushing area of the crushing device is increased, which improves the efficiency of bait crushing. The rotating blades on the crushing roller and the fixed cutting blades on the crushing platform form an interlaced layout, which generates stronger shearing and impact forces during the high-speed rotation of the crushing roller, so that the bait thrown up by the screening steel plate is fully crushed again, improving the uniformity of the fish bait.
[0012] Preferably, as an improvement, each mounting frame has a number of raised steel plates evenly distributed on the inner wall of the side near the rotating shaft, and the raised steel plates are inclined.
[0013] The beneficial effects are as follows: the tilted lifting steel plate generates an upward projectile force when rotating, which lifts up the substandard particles deposited at the bottom and makes them fall quickly onto the filter screen surface under the action of gravity. Then, together with the screening steel plate, they are thrown into the crushing area for crushing again, forming an efficient cycle processing process.
[0014] Preferably, as an improvement, the upper end of the crushing barrel is provided with a feed inlet, and the lower end of the crushing barrel is provided with a discharge outlet wrapped with a filter screen. Attached Figure Description

The grinding barrel 2 contains a grinding component and a screening component, such as... Figure 2 and Figure 3 The crushing assembly shown includes a motor 9, a first driving wheel 10, a first driven wheel 11, a first belt 12, and two sets of crushing rollers 13, as follows: Figure 2 The motor 9 shown is fixedly mounted on the upper left side of the mounting bracket 1, and the first drive wheel 10 is fixedly mounted on the output end of the motor 9, as shown. Figure 3 The two sets of crushing rollers 13 shown are symmetrically and rotatably mounted on the inner wall of the crushing barrel 2. Several crushing blades 14 are fixedly mounted on the outer wall of each crushing roller 13, and the crushing blades 14 on the outer walls of the two sets of crushing rollers 13 are staggered. Figure 2 As shown, gears 15 are fixedly installed on the right end of the crushing roller 13 that rotates through the crushing barrel 2, and the two gears 15 mesh with each other. The first driven wheel 11 is fixedly installed on the left end of the crushing roller 13 located on the front side, and the first belt 12 is tensioned and sleeved on the outer wall of the first driving wheel 10 and the first driven wheel 11.
[0023] The screening assembly includes a rotating shaft 4, a power component, and several mounting frames 5. The rotating shaft 4 is located inside the crushing barrel 2, and the power component is located on the outer wall of the crushing barrel 2. The power component can drive the rotating shaft 4 to rotate. Figure 3 Several mounting frames 5 are evenly fixedly installed on the outer wall of the rotating shaft 4, as shown. Figure 4 The mounting frame 5 shown is U-shaped, and a partition plate is fixedly installed on the inner wall of the mounting frame 5. Several screening steel plates 6 are evenly fixedly installed on the upper part of the partition plate, and the gap between each screening steel plate 6 is equal to the maximum aperture of the filter screen 3. Each screening steel plate 6 has a semi-circular groove 7 opened along the rotation direction of the rotating shaft 4. A brush 8 is fixedly installed on the upper part of the mounting frame 5, and the brush 8 can abut against the surface of the filter screen 3. Several raised steel plates 21 are fixedly installed between the left and right inner walls of the mounting frame 5, and the raised steel plates 21 are inclined and located below the partition plate. Figure 3 The grinding barrel 2 shown has grinding tables 19 symmetrically fixedly installed on its left and right inner walls.

[0024] The specific implementation process is as follows:
[0025] During use, the operator starts the motor 9, causing the crushing and screening components to rotate. Fish feed is then added to the crushing bin 2 through the feed inlet 22. Because the gears 15 at the ends of the two crushing rollers 13 mesh, the rollers 13 rotate synchronously in opposite directions. The crushing blades 14 on the two rollers 13 create a shearing action, initially crushing the fish feed material fed into the feed inlet 22. The initially crushed fish feed falls onto the surface of the filter screen 3 under gravity, with larger and heavier pieces of fish feed being... The first particles reach the surface of filter screen 3, causing it to become clogged and affecting its filtering effect. At this time, the rotating shaft 4 drives the mounting frame 5 to rotate above the filter screen 3, and works with the brush 8 to clean the surface of the filter screen 3 to prevent clogging. Then, under the action of the screening steel plate 6, the substandard bait particles are screened out and remain in the semi-circular groove 7. Then, under the action of centrifugal force, they are thrown back into the crushing area for secondary crushing, forming a closed-loop process of "crushing-screening-re-crushing", which significantly improves the uniformity of crushing and enhances the crushing effect of the fish bait.
