Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of ration machines, specifically to a horizontal total mixing ration machine capable of removing impurities. Background Technology
[0002] In modern livestock farming, the quality of total mixed ration (TMR) preparation directly affects livestock growth performance and farming efficiency. As a core piece of equipment for achieving uniform feed mixing, the functionality of horizontal TMR machines has received considerable attention. Traditional horizontal TMR machines are often designed to improve mixing uniformity and work efficiency, but they generally suffer from the technical drawback of not being able to effectively remove impurities from the feed.
[0003] In actual farming scenarios, feed ingredients to be mixed often contain foreign objects such as stones, metal shavings, and plastic fragments. If these impurities enter the livestock's digestive system with the feed, they can cause gastrointestinal damage and indigestion, or even infection or organ obstruction, significantly increasing the risk of livestock diseases. At the same time, hard impurities can also accelerate the wear and tear on the blades and liners inside the equipment during the mixing process, shortening the equipment's lifespan and increasing maintenance costs.
[0004] Although some farms add a manual screening step before feeding raw materials, this method is not only labor-intensive, but also highly susceptible to human error in terms of screening accuracy, making it difficult to completely remove fine impurities. Therefore, there is a clear market demand for horizontal total mixed ration (TMR) machines with integrated impurity removal functions. Structural optimization is urgently needed to address the impurity removal deficiencies of traditional equipment, thereby improving feed safety and equipment practicality. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a horizontal total mixed ration machine capable of removing impurities, which solves the technical problem that existing ration machines do not have the function of screening out impurities.
[0006] According to one aspect, at least one embodiment of this disclosure provides a horizontal total mixing ration machine capable of removing impurities, comprising:
[0007] The outer casing and the inner screen cylinder, wherein the inner screen cylinder is disposed within the outer casing;
[0008] A pair of circular plates and a mixing and impurity removal component, wherein the circular plates are fixed at both ends inside the outer shell, and the mixing and impurity removal component is disposed between the outer shell and the circular plates;
[0009] An infeed / outfeed assembly is disposed in the circular plate;
[0010] The mixing and impurity removal assembly includes an outer ring groove, which is formed around the outer surface of the circular plate. The inner screen cylinder is slidably connected to the outer ring groove. A rotating shaft is rotatably connected between the circular plates. The rotating shaft is driven by electricity to rotate. Several stirring racks are provided on the rotating shaft.

[0012] As a further technical solution, the drive gear meshes with the external gear, and a dust collection hood is provided on the top of the housing, with a suction pipe provided on the top of the dust collection hood.
[0013] As a further technical solution, the feeding and discharging assembly includes a feeding pipe, which is fixed to the side surface of the circular plate on one side, and an outer cover is provided on the side surface of the circular plate on the other side.
[0014] As a further technical solution, the outer cover and the inner screen cylinder are equipped with electrically driven push augers, the bottom of the outer cover is provided with a discharge pipe, one end of the feed pipe is inclined upwards, and the top of the feed pipe has a funnel-shaped opening structure.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] In this disclosure, the mixing and impurity removal component solves the problem of traditional feed mills being unable to remove impurities through a linked screening design.

[0032] like Figures 1-4 As shown, it illustrates a horizontal total mixed ration (TMR) machine capable of removing impurities according to an embodiment of this disclosure, comprising:
[0033] The outer shell 1 and the inner screen cylinder 2 are disposed in the outer shell 1;
[0034] A pair of circular plates 3 and a mixing and impurity removal component 4, wherein the circular plates 3 are fixed at both ends inside the outer shell 1, and the mixing and impurity removal component 4 is disposed between the outer shell 1 and the circular plates 3;
[0035] The feeding / discharging assembly 5 is disposed in the circular plate 3;
[0036] The mixing and impurity removal component 4 includes an outer ring groove 4-1, which is formed around the outer surface of the circular plate 3. The inner screen cylinder 2 is slidably fitted inside the outer ring groove 4-1. A rotating shaft 4-2 is rotatably connected between the circular plates 3. The rotating shaft 4-2 is driven by electricity to rotate. Several stirring racks 4-3 are provided on the rotating shaft 4-2. An opening 4-4 is provided at the top of the outer shell 1. An external gear 4-5 is provided around the outer surface of the inner screen cylinder 2. A partition 4-6 is provided around the inner wall of the outer shell 1, covering both sides of the external gear 4-5. A drive gear 4-7, which is driven by electricity to rotate, is provided at the top of the outer shell 1. The drive gear 4-7 meshes with the external gear 4-5. A dust collection hood 4-8 is provided at the top of the outer shell 1, and a suction pipe 4-9 is provided at the top of the dust collection hood 4-8.
[0037] In some examples, a mixing and impurity removal component 4 is designed to achieve mixing and separation of the diet. This component includes circular plates 3 fixed at both ends of the inner shell 1 by welding. An outer ring groove 4-1 around the outer surface is an annular groove. The flanges at both ends of the inner screen cylinder 2 are slidably fitted into the groove and can rotate freely along the circular plates 3. Screen holes are evenly distributed on the cylinder wall for separating impurities. A rotating shaft 4-2 is rotatably connected to the center of the circular plates 3 via a bearing and is driven by a motor through chain transmission. The stirring frame 4-3 on the shaft is spirally distributed and maintains a certain gap with the inner wall of the inner screen cylinder 2, allowing it to agitate the material during rotation. An external gear 4-5 around the outer surface of the inner screen cylinder 2 meshes with a drive gear 4-7 driven by a motor at the top of the outer shell 1. A semi-annular shroud 4-6 on the inner wall of the outer shell 1 covers both sides of the external gear 4-5 to prevent material from being drawn into the gear meshing area. A dust collection hood 4-8 at the top of the outer shell 1 is fixed by a bracket, covering the area above the inner screen cylinder 2. A suction pipe 4-9 connects the dust collection hood 4-8 to a negative pressure device. During operation, the drive gear 4-7 rotates the external gear 4-5, causing the inner screen cylinder 2 to rotate along the outer ring groove 4-1. Simultaneously, the rotating shaft 4-2 drives the stirring frame 4-3 to rotate synchronously. The stirring frame 4-3 continuously tumbles and pushes the material inside the inner screen cylinder 2, ensuring full contact between the material and the inner screen cylinder 2. Impurities in the material (such as stones, metal shavings, etc.) that are larger than the screen holes are trapped and discharged to the bottom impurity outlet as the inner screen cylinder 2 rotates. Qualified material passes through the screen holes and enters the chamber between the outer shell 1 and the inner screen cylinder 2. Dust generated during the stirring process is sucked away by the dust collection hood 4-8 through the suction pipe 4-9, reducing environmental pollution.
[0038] The outer ring chute 4-1 ensures smooth rotation of the inner screen cylinder 2, the spiral agitator 4-3 improves mixing uniformity, the meshing of the outer gear 4-5 and the drive gear 4-7 achieves stable drive of the inner screen cylinder 2, and the diaphragm 4-6 ensures safe gear transmission. This component, through the coordinated operation of agitation and sieving, achieves thorough mixing of the diet and efficient separation of impurities, thereby improving the quality of the diet.
[0039] like Figures 1-4 As shown in the figure, the feeding and discharging assembly 5 in this embodiment includes a feeding pipe 5-1, which is fixed to the side surface of the circular plate 3 on one side. An outer cover 5-2 is provided on the side surface of the circular plate 3 on the other side. An electrically driven pusher auger 5-3 is provided in the outer cover 5-2 and the inner screen cylinder 2. A discharge pipe 5-4 is provided at the bottom of the outer cover 5-2. One end of the feeding pipe 5-1 is inclined upward, and the top of the feeding pipe 5-1 has a funnel-shaped opening structure.
[0040] In some examples, in order to achieve smooth feeding and orderly discharge of the ration, a feeding and discharging assembly 5 is designed. This assembly includes a feeding pipe 5-1 fixed by welding on the side surface of a circular plate 3 on one side, which is inclined upwards and has a flared opening at the top. An outer cover 5-2 is fixed by welding to the surface of the other circular plate 3 and is connected to the end of the inner screen cylinder 2. The internal pusher auger 5-3 is rotatably connected between the circular plate 3 and the outer cover 5-2 through a bearing and is driven to rotate by a motor. The discharge pipe 5-4 at the bottom of the outer cover 5-2 is vertically downward and is connected to the inner cavity of the outer cover 5-2.
[0041] During operation, the feed rations to be processed are poured in through the funnel-shaped opening of the feed pipe 5-1. The inclined structure uses gravity to guide the material into the inner screen cylinder 2. The funnel opening expands the feeding area, preventing material spillage, and the inclined angle design prevents material accumulation and blockage. While the material entering the inner screen cylinder 2 is mixed by the mixing rack 4-3, it is gradually conveyed to the discharge end by the auger 5-3. The auger blades cooperate with the inner wall of the inner screen cylinder 2 to evenly push the material into the outer cover 5-2, and finally discharge it from the discharge pipe 5-4. The inclined angle of the feed pipe 5-1 and the funnel-shaped opening structure are adapted to different feeding methods (such as manual pouring and mechanical conveying). The rotation direction and speed of the auger 5-3 can be matched with the mixing speed to ensure that the material is fully mixed before discharge. The sealed connection between the outer cover 5-2 and the inner screen cylinder 2 prevents material leakage, and the position of the discharge pipe 5-4 facilitates connection to subsequent conveying equipment. This component, through the combination of guiding and pushing, achieves smooth feeding and orderly discharge, ensuring continuous operation of the entire machine.
[0042] For example, such as Figure 2 As shown, the bottom of the outer shell 1 protrudes downward in an arc shape, both sides of the outer shell 1 are open structures, and a baffle 6 is provided on one side of the bottom of the outer shell 1.
[0043] In some examples, the downward-curving arc at the bottom of the outer casing 1 allows qualified material passing through the inner screen cylinder 2 to naturally converge at the bottom, facilitating centralized collection. The openings on both sides allow for easy cleaning or maintenance, facilitating the removal of residual material between the outer casing 1 and the inner screen cylinder 2. A baffle 6 on one side of the bottom prevents material from flowing out unnecessarily; the baffle 6 can be opened as needed to control material discharge. The arc-shaped design reduces dead zones for material accumulation, improving the internal cleaning efficiency of the outer casing 1.
[0044] For example, such as Figure 3 As shown, several push rods 7 are connected between several of the stirring racks 4-3.
[0045] In some examples, the push rods 7 connected between several mixing racks 4-3 can enhance the pushing and mixing effect of materials. The push rods 7 and the mixing racks 4-3 form a three-dimensional mixing structure, which can turn the material from the bottom of the inner screen cylinder 2 upwards when rotating, avoiding the accumulation of material at the bottom, allowing the material to have more sufficient contact with the inner screen cylinder 2, improving the screening efficiency of impurities, and making the mixture of different components of the diet more uniform, thus improving the overall mixing quality.
[0046] For example, such as Figure 3 As shown, the bottom of the pusher auger 5-3 is slidably attached to the bottom of the inner screen cylinder 2.
[0047] In some examples, the bottom of the auger 5-3 slides and fits against the bottom of the inner screen cylinder 2, ensuring that the material inside the inner screen cylinder 2 is completely pushed out and avoiding residue. This fitting design allows the auger blades to scrape off the material at the bottom of the inner screen cylinder 2, preventing material adhesion and accumulation. Especially for diets with high moisture content, it ensures smooth pushing. Combined with the turning action of the mixing rack 4-3, the material is pushed into the outer cover 5-2 after being evenly mixed, improving material utilization and the thoroughness of discharge.
[0048] In actual use: Feed raw materials are poured into the flared end of the feed pipe 5-1. The inclined pipe guides the material into the inner screen cylinder 2. The drive gear 4-7 drives the outer gear 4-5 to rotate the inner screen cylinder 2. At the same time, the rotating shaft 4-2 drives the stirring frame 4-3 and the push rod 7 to tumble and stir the material. Impurities in the material are trapped by the inner screen cylinder 2 and discharged to the bottom as the cylinder rotates. Qualified material enters the inner cavity of the outer shell 1 through the screen holes. The push auger 5-3 conveys the processed material to the discharge end and finally discharges it from the discharge pipe 5-4 at the bottom of the outer cover 5-2. During operation, the dust collection hood 4-8 absorbs dust through the suction pipe 4-9. To clean impurities, simply open the baffle 6. The entire process achieves simultaneous mixing, impurity removal, and dust removal.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
