Technical Field
[0001] This utility model relates to the field of feed production technology, specifically a grinding and screening device for feed production. Background Technology
[0002] Feed is a general term for the food of all artificially raised animals. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, additives, whey powder, oils, meat and bone meal, grains, and sweet sorghum. Feed is an indispensable part of modern animal husbandry. Feed ingredients are usually large particles. In order to promote the digestion and absorption of livestock, feed ingredients need to be ground. Grinding feed ingredients requires the use of a grinder.
[0003] Currently, traditional feed grinding equipment often fails to guarantee the grinding fineness during the grinding process. The particle size distribution of the ground material may be uneven, and particles of different sizes may be mixed together, which may lead to the final product not meeting the specific particle size requirements, affecting the effectiveness of feed additives and the uniformity of mixing. Therefore, a grinding and screening device for feed production is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 The grinding and screening device for feed production in this embodiment includes a first frame 1, a grinding mechanism 2 fixedly connected to the top of the first frame 1, a feeding mechanism 4 fixedly connected to the top of the first frame 1, and a screening mechanism 3 provided at one end of the first frame 1.
[0022] The screening mechanism 3 includes a second frame 301 located on one side of the first frame 1. A telescopic sleeve 308 is fixedly connected to the top of the second frame 301. A spring 307 is provided on the outer surface of the telescopic sleeve 308. A collection box 304 is fixedly connected to the top of the telescopic sleeve 308. The top and bottom of the telescopic sleeve 308 are fixedly connected to the second frame 301 and the collection box 304, respectively. The top and bottom of the spring 307 are fixedly connected to the second frame 301 and the collection box 304, respectively. A screen plate 306 is detachably fixedly connected inside the collection box 304. An mounting plate 302 is fixedly connected to the top of the collection box 304. A vibration motor 303 is fixedly connected to the top of the mounting plate 302. The top of the collection box 304 is open, the bottom is closed, and the inner bottom wall is inclined. A discharge plate 305 is fixedly connected to one end of the collection box 304, and a discharge port is opened at one end of the collection box 304.
[0023] The ground raw materials enter the collection box 304. The vibration motor 303 is started to drive the collection box 304 to vibrate. The telescopic sleeve 308 and spring 307 are set to limit the regular up-and-down vibration of the collection box 304 to achieve the effect of vibration screening. The screened material is discharged through the inner bottom wall of the collection box 304 and the feeding plate 305. The raw materials that do not pass the screening are discharged through the opening on one side of the collection box 304.
[0024] Secondly, the grinding mechanism 2 includes a motor 201 fixedly connected to the top of the first frame 1, a reducer 202 at one end of the motor 201, a grinding cylinder 203 at the top of the reducer 202, a grinding roller 205 fixedly connected to the top of the output shaft of the reducer 202, a grinding plate 204 fixedly connected inside the grinding cylinder 203, and a perforation hole inside the grinding cylinder 203. A guide plate 206 is fixedly connected to one end of the grinding cylinder 203, and the guide plate 206 is located at the top of the screening mechanism 3.
[0025] The grinding mechanism 2 drives the grinding roller 203 to work with the grinding plate 204 to achieve fine grinding of raw materials, which satisfies the effect of grinding feed. The ground raw materials are guided to the inside of the collection box 304 by the guide plate 206.
[0026] Additionally, the feeding mechanism 4 is a screw conveyor, but it can also be any other mechanism capable of transporting materials. The screw conveyor's discharge pipe is located at the top of the grinding mechanism 2.
[0027] The working principle of the above embodiments is as follows:
[0028] (1) The grinding and screening device for feed production, after grinding, enters the collection box 304. The vibration motor 303 is started to drive the collection box 304 to vibrate. The vibration of the collection box 304 can be restricted by the telescopic sleeve 308 and the spring 307 to achieve the effect of vibration screening. The screened material is discharged through the inner bottom wall of the collection box 304 and the feeding plate 305. The unscreened material is discharged through the opening on one side of the collection box 304.
[0029] (2) The grinding and screening device used for feed production uses a vibration motor 303 to drive the collection box 304 to vibrate, so that the material can be quickly dispersed on the screen plate 306 and pass through the screen holes efficiently, which effectively improves the screening efficiency. At the same time, the screen plate can be replaced according to actual needs to adapt to screening operations with different particle size requirements, ensuring the uniformity of the particle size of the final product and improving the product quality.
