Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal husbandry technology, specifically a screening device for concentrated feed for ruminants. Background Technology
[0002] Ruminant concentrate feed is a high-energy, high-protein, and highly nutrient-concentrated supplementary feed. It is specifically designed to supplement the nutritional deficiencies of basic roughage. Its main components are grains such as corn, barley, wheat, sorghum, wheat bran, and rice bran meal, as well as their processing by-products. Screening is an important step in feed processing and quality control. It is used to ensure that the feed particle size meets the requirements, remove foreign matter introduced into the raw materials or generated during processing, and ensure that materials with relatively uniform particle size are easier to mix evenly, thus ensuring that each portion of feed contains the predetermined proportions of various nutrients and additives.
[0003] In actual use, friction during screening causes temperature rise, which leads to the degradation of heat-sensitive nutrients such as vitamin C and enzyme preparations. Therefore, there is an urgent need to propose a screening device that can effectively reduce the temperature during screening to solve the above problems. Summary of the Invention
[0004] To address the above problems, the purpose of this utility model is to provide a screening device for ruminant supplementary feed, which solves the problem of degradation of heat-sensitive nutrients such as vitamin C and enzyme preparations caused by frictional heating during screening.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for ruminant supplementary feed, comprising a device body, a screening screen inside the device body, a hollow layer inside the outer shell of the device body, a circulation pipe installed on the outer side of the device body via a flange, nozzles installed at equal intervals at one end of the circulation pipe, a filter bag connected to the other side of the circulation pipe, a blocking net installed on the side of the filter bag near the device body, a fan installed in the middle of the circulation pipe, and a cooling device installed at the bottom of the device body.
[0006] The beneficial effects of this utility model are as follows: When using this device, the water pump delivers the coolant in the water storage tank to the hollow layer through the water inlet pipe.

The fan realizes the gas flow inside the device body through the circulation pipe, which can effectively reduce the internal temperature of the device body.
[0007] The fan drives the gas flow inside the device through the circulation pipe, which can work with filter bags and screens to reduce dust inside the device.
[0008] To facilitate the screening of raw materials by the main body of the device:

[0013] The beneficial effects of this improvement are as follows: the water pump delivers the coolant in the water storage tank to the hollow layer through the water inlet pipe. The hollow layer provides comprehensive and rapid cooling to the outer wall of the device body. Afterward, the coolant flows back into the interior of the water storage tank through the return pipe to circulate and cool the device body.
[0014] To reduce dust in the raw materials during screening:
[0015] As a further improvement to the above technical solution: the fan drives the gas flow in the circulation pipe, and the circulation pipe draws the gas in the device body into the filter bag through the filter bag and the baffle. The gas continues to flow, and after passing through the circulation pipe, the gas enters the interior of the device body through the nozzle and blows the gas from bottom to top, causing the dust to enter the interior of the filter bag.
[0016] The beneficial effects of this improvement are as follows: the fan drives the gas in the circulation pipe to flow from one end of the filter bag to one end of the nozzle through the circulation pipe, and the gas in the device body flows into the interior of the filter bag from bottom to top. The dust in the airflow can be filtered by the filter bag in conjunction with the baffle net.
[0017] To facilitate cooling of the water storage tank:
[0018] As a further improvement to the above technical solution: heat dissipation fins are welded to the outer circumferential side of the water storage tank.
[0019] The beneficial effects of this improvement are: the heat dissipation fins can provide comprehensive and reliable cooling of the water tank, ensuring the efficiency of the circulating cooling.

[0022] The beneficial effects of this improvement are: the vibration motor drives the device body to vibrate, and at this time the base, together with the helical spring, ensures the stability of the device body during vibration.
[0023] To facilitate material arrangement:
[0024] As a further improvement to the above technical solution: both the fine filler outlet and the impurity outlet are fitted with soft channels.
[0025] The beneficial effects of this improvement are: the soft channel can block a certain amount of dust and can reliably transport the screened raw materials into the collection box.
[0026] To facilitate the rotation of the feeding plate:
[0027] As a further improvement to the above technical solution: a bearing is installed at the connection between the feeding plate and the feeding hopper.
[0028] The beneficial effects of this improvement are: the rotation of the feed plate can be limited by the bearing, and the friction force when the feed plate rotates can also be reduced. Attached Figure Description

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0036] like Figure 1-5As shown, a sieving device for ruminant supplemental feed includes a device body 1. A sieving screen 4 is installed inside the device body 1, and a hollow layer 16 is formed inside the outer shell of the device body 1. A circulation pipe 2 is installed on the outer side of the device body 1 via a flange. Nozzles 22 are installed at equal intervals at one end of the circulation pipe 2, and a filter bag 24 is connected to the other side of the circulation pipe 2. A blocking net 23 is installed on the side of the filter bag 24 closest to the device body 1. A fan 21 is installed in the middle of the circulation pipe 2. A cooling device is installed at the bottom of the device body 1. When using the device, a water pump 31 transports coolant from a water storage tank 3 to the hollow layer 16 through an inlet pipe 32, and the hollow layer 16 circulates and cools the outer wall of the device body 1. The blower 21 circulates gas within the device body 1 through the circulation pipe 2, effectively reducing the internal temperature of the device body 1. The blower 21, by driving the gas flow within the device body 1 through the circulation pipe 2, works in conjunction with the filter bag 24 and the baffle net 23 to reduce dust inside the device body 1. A feed hopper 11 is located at the top of the device body 1, and a drive motor 12 is installed on the outside of the feed hopper 11. A material guide plate 13 is installed at the output end of the drive motor 12. Fine feed outlets 14 and impurity outlets 15 are staggered at the bottom of the device body 1. A vibration motor 6 is installed at the bottom of the device body 1. The drive motor 12 rotates the material guide plate 13, controlling the smooth flow of raw materials into the device body 1. The device 6 can drive the main body 1 to vibrate and screen the raw materials. Materials meeting the requirements are discharged through the fine feed outlet 14, while large particles and impurities are discharged through the impurity outlet 15. The cooling device includes a water storage tank 3, which is installed at the bottom of the main body 1. A water pump 31 is installed inside the water storage tank 3, and an inlet pipe 32 is installed on the water pump 31. The top of the inlet pipe 32 is connected to the hollow layer 16. A return pipe 33 is connected to the outside of the water storage tank 3, and the other end of the return pipe 33 is connected to the hollow layer 16. The water pump 31 transports the coolant from the water storage tank 3 to the hollow layer 16 through the inlet pipe 32. The hollow layer 16 provides comprehensive and rapid cooling to the outer wall of the main body 1. Afterward, the coolant returns through the return pipe 33. The gas flows into the water storage tank 3, circulating and cooling the device body 1. The fan 21 drives the gas flow in the circulation pipe 2. The circulation pipe 2 draws the gas from the device body 1 into the filter bag 24 through the filter bag 24 and the baffle 23. The gas continues to flow and, after passing through the circulation pipe 2, enters the device body 1 through the nozzle 22, blowing the gas from bottom to top, causing dust to enter the filter bag 24. The fan 21 drives the gas in the circulation pipe 2 to flow from one end of the filter bag 24 to one end of the nozzle 22. The gas in the device body 1 flows from bottom to top into the filter bag 24. The baffle 23, in conjunction with the filter bag 24, filters the dust in the airflow. The water storage tank 3 has heat dissipation fins welded to its outer circumference.The heat dissipation fins provide comprehensive and reliable cooling to the water storage tank 3, ensuring efficient circulating cooling. A base 5 is inserted into the bottom of the device body 1, and a helical spring 51 is fitted underneath the device body 1. The vibration motor 6 drives the device body 1 to vibrate. The base 5, in conjunction with the helical spring 51, ensures the stability of the device body 1 during vibration. Flexible channels are fitted onto both the fine feed outlet 14 and the impurity outlet 15. These channels can block some dust and facilitate the reliable transport of the screened raw materials into the collection box. A bearing is installed at the connection between the material feeding plate 13 and the feed hopper 11. The bearing limits the rotation of the material feeding plate 13 and reduces friction during rotation.
[0037] The working principle of this utility model is as follows: When using the device, the water pump 31 transports the coolant in the water storage tank 3 to the hollow layer 16 through the water inlet pipe 32. The hollow layer 16 cools the outer wall of the device body 1 rapidly and comprehensively. Then, the coolant flows back into the interior of the water storage tank 3 through the return pipe 33 to circulate and cool the device body 1. The fan 21 drives the gas in the circulation pipe 2 to flow from one end of the filter bag 24 to one end of the nozzle 22 through the circulation pipe 2. The gas in the device body 1 flows into the interior of the filter bag 24 from bottom to top. The dust in the airflow can be filtered by the baffle net 23 in conjunction with the filter bag 24. The raw material is put into the interior of the feed hopper 11 and the vibration motor 6 is turned on. The vibration motor 6 drives the device body 1 to vibrate. At this time, the base 5 and the spiral spring 51 ensure the stability of the device body 1 during vibration. The drive motor 12 drives the feeding plate 13 to rotate. The raw material reaches the top of the screening screen 4 and is screened by the screening screen 4. The material that meets the requirements is discharged through the fine feed outlet 14, and large particles and impurities are discharged through the impurity outlet 15.
