Description

Technical Field

[0001] The utility model relates to the technical field of feed, in particular to a screening device for feed production. Background Art

[0002] Feed is the food used by people to raise chickens, ducks, geese, pigs, cattle, sheep, sea cucumbers, abalone and other aquatic products. Feed usually includes soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives and other raw materials. According to the different production needs of the animals, feeds of different sizes and precisons are often used. Therefore, in the process of feed processing, it is often necessary to crush the feed raw materials and then screen them.

[0003] Patent No. CN219723193U discloses a feed crushing and screening device for feed production, including a crushing and screening box, a slot is provided at the front end of the crushing and screening box, a screen frame is inserted in the slot, a material taking port is provided on the left and right sides of the crushing and screening box, a first motor is fixedly installed on the right side of the crushing and screening box, a first threaded rod is fixedly installed on the output end of the first motor, a first push plate is sleeved on the first threaded rod, a scraper is fixedly installed on the left side of the first push plate, and a second motor is fixedly installed on the left side of the crushing and screening box. The feed crushing and screening device for feed production can use the first push plate and the second push plate to completely push out the crushed raw materials, so that the feed raw materials are collected more thoroughly, thereby further improving the utilization rate of the feed raw materials. At the same time, the scraper can be used to automatically clean the screen frame when collecting the feed raw materials, avoiding the problem that the traditional equipment needs to take out the screen for cleaning, which is time-consuming and labor-intensive, and easily affects the work efficiency. When the above scheme is used for feed screening, feed with a mesh size similar to that of the screen frame is easily stuck on the surface of the screen frame, and the screen frame needs to be frequently taken out and cleaned, which is cumbersome to operate and is not conducive to the screening efficiency of the feed. To this end, we propose a screening device for feed production. Utility Model Content

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] like Figure 1-3 As shown, a screening device for feed production includes a crushing and screening box 1 for feed screening, and also includes an oscillating motor 7 detachably connected to the back of the crushing and screening box 1 for preventing feed from getting stuck. The bottom of the crushing and screening box 1 is provided with a support plate 9 that can be raised and lowered. The back of the crushing and screening box 1 is fixedly connected with a mounting frame 5, and the mounting frame 5 is detachably connected to the oscillating motor 7. One side of the outer side of the mounting frame 5 is threadedly connected with a through bolt 6, and one end of the bolt 6 is glued to a foam block 8; the oscillating motor 7 is installed inside the mounting frame 5 on the back of the crushing and screening box 1, and the oscillating motor 7 is fixed by connecting the foam block 8 with the bolt 6, so as to facilitate the installation and disassembly of the oscillating motor 7. Under the action of the oscillating motor 7, the screen frame inside the crushing and screening box 1 is driven to oscillate, thereby preventing feed with a mesh size similar to that of the screen frame from getting stuck on the surface of the screen frame, thereby ensuring the screening effect of the feed.

[0016] Among them, the back of the crushing and screening box 1 is fixedly connected with an electric push rod 2 at a position below the mounting frame 5, the output end of the electric push rod 2 is connected to a support plate 9, and the output end of the electric push rod 2 is connected to a lifting rod 3, the bottom of the lifting rod 3 is fixedly connected with a card plate 4, the side of the card plate 4 is fixedly connected to the support plate 9, and a limit plate 10 is provided below the support plate 9, and springs 11 evenly arranged are glued and connected between the support plate 9 and the limit plate 10; the lifting rod 3, the card plate 4 and the support plate 5 are driven downward by the electric push rod 2, and then the limit plate 10 is driven downward until the limit plate 10 contacts the ground and the spring 11 is in a compressed state. When the crushing and screening box 1 and the screen frame inside it vibrate, the support plate 9 is connected to the spring 11 and the limit plate 10, The effect of shock absorbing of the crushing and screening box 1 on the ground is achieved, and the noise reduction effect is achieved at the same time.

[0017] It should be noted that the utility model is a screening device for feed production. When working, the oscillation motor 7 is first placed inside the mounting frame 5, and the bolts 6 are tightened to drive the foam block 8 to move and fix the oscillation motor 7. Then, the oscillation motor 7 and the electric push rod 2 are powered on, and the electric push rod 2 is started to drive the lifting rod 3, the clamping plate 4 and the support plate 5 to move downward, and then the limit plate 10 is driven to move downward until the limit plate 10 contacts the ground and the spring 11 is in a compressed state. The oscillation motor 7 is started to drive the screen frame inside the crushing and screening box 1 to oscillate, and then it prevents feed with a mesh size similar to that of the screen frame from being stuck on the surface of the screen frame, thereby ensuring the screening effect of the feed. When the crushing and screening box 1 and the screen frame inside it oscillate, under the action of the support plate 9 connecting the spring 11 and the limit plate 10, the crushing and screening box 1 has a shock-absorbing effect on the ground, and at the same time achieves a noise reduction effect.
