[0012] Beneficial Effects

[0013] Compared with the prior art, the raw material crusher used in the preparation of shrimp seed material of the utility model has the following advantages:

[0014] 1. The first motor rotates, so that the two crushing rollers cooperate with each other to crush the feed raw materials. The crushed raw materials will fall into the grinding block through the holes in the screen. At the same time, the second motor is started to rotate. The second motor will drive the grinding block to crush the raw materials again, so that the particles are ground to a uniform size, and finally discharged through the discharge ports on both sides of the grinding block. The raw materials of shrimp seedlings that have been crushed many times have improved the quality of the feed production process to a certain extent and avoided the waste of raw materials.

[0015] 2. Since the feed hopper and the box body are connected through the card slot and block under the action of the telescopic spring, and the pull rod is fixedly connected to the card block, when the crusher needs to be moved or repaired, the card block can be disengaged from the card slot by pulling the pull rod outward. At this time, the feed hopper and the box body can be separated by moving upward, and the inside of the box body can be inspected from the position of the feed hopper.

[0016] 3. There is a cover installed on one side of the box through a hinge. During maintenance, the cover can be opened with a key, and the handle can be pulled to allow the inside of the crusher to be inspected from the side. The operation is convenient and labor-saving, and the efficiency is improved.

[0017] 4. At the end of feeding, the baffle connected to the feed hopper through the hinged seat above the feed hopper will close the feed hopper under the action of the tension spring, and the baffle rod will limit the baffle. The baffle can prevent the raw materials from splashing out during the crushing process and foreign objects from entering the feed hopper to cause raw material contamination. The effect is good, and the operation is convenient and labor-saving.

[0018] 5. Water can be sprayed onto the crushing roller through the nozzle to clean the crushing roller.

[0027] Example

[0028] The specific implementation of the utility model is as follows Figures 1 to 4 As shown, a raw material crusher for preparing shrimp seed feed includes a housing 1, and the housing 1 is provided with a feed hopper 4, a pair of two crushing rollers 2, a screen 8, a grinding mechanism and a discharge port 5 in order from top to bottom. The lower end of the feed hopper 4 is plugged into and matched with the top of the housing 1, and the two are locked by a snap-fit ​​structure 7. The raw material crusher also includes a cleaning structure, which includes a nozzle 16 located in the housing 1 and facing the crushing roller 2. The raw materials can be crushed in turn by the crushing roller 2 and the grinding mechanism so that the particle size of the feed is uniform. The screen 8 can filter out some materials with larger particles that are difficult to crush. The housing 1 is connected to a base 9.

[0029] The top of the box body 1 is provided with a plug-in slot that matches the lower end of the feed hopper 4. The clamping structure 7 includes a pull rod 704 that passes through the side wall of the plug-in slot, and one end of the pull rod 704 located on the inner side of the plug-in slot is connected to a clamping block 702, and a telescopic spring 701 is connected between the clamping block 702 and the inner wall of the plug-in slot. A clamping slot 703 is provided on the outer wall of the feed hopper 4, and the clamping block 702 is adapted to the clamping slot 703. Pulling the pull rod 704 outwards allows the clamping block 702 to overcome the elastic force of the telescopic spring 701, so that the clamping block 702 can be disengaged from the clamping slot 703, thereby pulling the feed hopper 4 out of the plug-in slot at the top of the box body 1. The feed hopper 4 is provided with clamping slots 703 on both sides.

[0030] Two symmetrically arranged baffles 11 are hinged on the inner wall of the middle part of the feed hopper 4, and a tension spring 15 is hinged between the bottom of the baffle 11 and the inner wall of the feed hopper 4 through a hinge seat. A stopper 14 is also provided on the side wall of the feed hopper 4, which is located above the baffle 11. The two baffles 11 and the tension spring 15 are symmetrically arranged with respect to the central axis of the feed hopper 4, so that when the raw material crusher crushes the raw material, the feed raw material is prevented from splashing out of the feed hopper 4 and affecting the user.

[0031] The grinding mechanism includes a grinding block 6 and a grinding cylinder which are arranged inside and outside respectively. The grinding cylinder is fixedly connected to the housing 1. The grinding block 6 is rotatably connected to the housing 1 and is linked to a second motor 10. The second motor 10 is installed at the bottom of the housing 1, and the grinding block 6 is connected to the rotating shaft of the second motor 10. The outer wall of the grinding block 6 and the inner wall of the grinding cylinder are both conical. Multiple protrusions can be provided on the conical surfaces of both the grinding block 6 and the grinding cylinder to improve the grinding efficiency. The screen 8 is arranged at the upper end opening of the grinding cylinder, and the discharge port 5 is arranged below the grinding cylinder and between the grinding block 6 and the grinding cylinder. There are two discharge ports 5 and they are symmetrically arranged on the left and right sides of the grinding block 6.

[0032] A cover plate 17 is hingedly connected to the side wall of the box body 1 through a hinge, and a handle 18 is provided on the cover plate 17. A waterproof pad is glued to the outer periphery of the cover plate 17, which can facilitate the cleaning of the crusher and keep the internal environment of the crusher clean.

[0033] Among the two crushing rollers 2, the rotating shaft of one crushing roller 2 is connected to a driving gear 12, and the rotating shaft of the other crushing roller 2 is connected to a driven gear 13, and the driven gear 13 is meshed with the driving gear 12. The driving gear 12 is linked to a first motor 3, and specifically, the first motor 3 is installed outside the box 1.

[0034] The working principle of the utility model is as follows: when in use, the raw materials are put into the crusher through the feed hopper 4. When the raw materials are put into the crusher, the baffle 11 installed inside the feed hopper 4 closes the feed hopper 4 under the action of the tension spring 15 and the baffle rod 14 to prevent the raw materials from splashing during crushing and foreign objects from entering the feed hopper 4. At the same time, the first motor 3 is started to drive the crushing roller 2 to rotate to crush the raw materials. The crushed raw materials will fall onto the grinding block 6 through the screen 8, and the second motor 10 drives the grinding block 6 to rotate. The materials pass through the gap between the conical surfaces of the grinding block 6 and the grinding cylinder and are further ground and crushed, and then the crushed raw materials are discharged through the discharge port 5 on both sides of the grinding block 6. When the crusher needs to be disassembled and maintained, the feed hopper 4 is separated by pulling the pull rods 704 on both sides of the feed hopper 4, so that the disassembly and installation of the feed hopper 4 becomes more convenient; the cover plate 17 is opened by the key, and the handle 18 is pulled open to clean the inside of the crusher.

[0035] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
