Description

Technical Field

[0001] This utility model relates to a multi-sloping-plane shearing feed mixer. Background Technology

[0002] Shear mixers are used to uniformly mix various raw materials and then cut them into pellets or other shapes of feed. Because feed raw materials are diverse in type, specification, and density, including various forages, crop straws, silage, and other fibrous feeds, as well as powdered or granular concentrates, ensuring uniform mixing is a challenge. Incomplete mixing leads to nutritional imbalances. To address this, existing shear mixers use augers and cutters to convey, cut, and mix materials. However, for settled powders or pellets, traditional augers can only convey them towards the outlet but cannot lift them, resulting in these settled materials not being uniformly mixed with other materials. Utility Model Content

[0003] The purpose of this invention is to provide a multi-sloping-plane shearing feed mixer to solve the technical problem that the bottom material cannot be effectively lifted and thus cannot be fully mixed with other materials.

[0004] The technical solution of this utility model is as follows: A multi-sloping-plane shearing feed mixer, comprising:

[0005] The mixing chamber has a receiving slot at the bottom;

[0006] The conveying auger is rotatably assembled in a receiving groove, including a rotating shaft and spiral conveying blades surrounding the rotating shaft;

[0007] The cutter is installed on the conveyor auger;

[0008] The lifting spiral belt is fixed in a spiral shape on the outer edge of the spiral conveyor blade. It includes two lifting parts, which extend outward from the two sides of the spiral conveyor blade. The lifting parts are made of elastic material and the outer surface of the lifting parts can elastically contact the wall of the receiving trough.

[0009] When the lifting screw belt rotates with the screw conveyor blades, it can lift up the bottom material in the receiving tank and mix it with other materials.

[0010] Based on the above scheme, the following improvements are made: the lifting section is an arc-shaped spiral ribbon structure. Compared with a flat surface, the arc-shaped spiral ribbon structure of the lifting section has a certain degree of effect in accommodating and retaining loose materials. Because the arc shape is a concave structure, it can improve the accommodating and retaining effect, delaying the falling of materials and thus lifting the loose materials higher, thereby further improving the mixing effect and making the mixing more uniform.

[0011] Based on the above scheme, the following improvements are made: the outer edge of the lifting section is provided with chamfered sections of progressively decreasing thickness. By providing chamfered sections of progressively decreasing thickness, the outer edge of the lifting section can more easily allow the loose material to pass through and fit against the wall of the receiving tank, or in other words, it is easier for the loose material in the receiving tank to enter the lifting section, thereby increasing the amount of loose material that can be lifted and thus improving the mixing effect.

[0012] Based on the above solution, further improvements are made as follows: the auger belt is made of rubber and is fixed to the auger conveyor blades through vulcanization. This structure requires no further installation and is more robust and reliable.

[0013] Based on the above scheme, further improvements are made as follows: The lifting spiral belt includes a U-shaped metal skeleton and the lifting section vulcanized on the metal skeleton. Multiple bolt holes are correspondingly provided on the metal skeleton and the spiral conveyor blades, spaced apart along their length, and the metal skeleton is fixed relative to the spiral conveyor blades using bolts. This structure of the metal skeleton improves the overall strength and rigidity of the lifting spiral belt and also facilitates the provision of bolt holes for connection with the spiral conveyor blades.

[0014] Based on the above solution, further improvements are made as follows: the lifting screw conveyor is composed of multiple arc-shaped segments spliced ​​together. This structure not only facilitates the production, transportation, and disassembly of the lifting screw conveyor, but also helps to reduce various costs.

[0015] Based on the above scheme, further improvements are made as follows: the bottom of the receiving tank has a multi-sloped splicing structure. This multi-sloped splicing structure allows the receiving tank to be directly formed by bending steel plates, making processing more convenient. Furthermore, due to the multi-sloped splicing, the inclination angles of each slope are different. This means that when the lifting section contacts adjacent slopes sequentially from below, the steeper inclination angle of the next slope makes it easier for nearby loose material to fall onto the lifting section, thereby improving the mixing effect.

[0016] Based on the above scheme, further improvements are made as follows: Two symmetrically arranged receiving tanks are set side by side in the mixing chamber. The two receiving tanks are respectively equipped with the aforementioned conveying auger and a corresponding lifting spiral belt. Each conveying auger has two symmetrically arranged spiral conveying blades with opposite spiral directions. This design of opposite spiral directions allows material on both sides to move towards the center along the axial direction of the rotating shaft. Then, when a large amount of material accumulates in the center, it can tumble towards both sides, thus better mixing the materials and facilitating multiple cuts of the fibrous material, resulting in more uniform cutting.

[0017] Based on the above scheme, the following improvements are made: multiple cutters are arranged at intervals along the length of the spiral conveyor blades, and the cutters are quincunx blades.

[0018] The beneficial effects of this utility model are as follows: When the multi-sloping-plane shearing feed mixer of this utility model is in use, materials of various shapes, specifications, densities, and diameters, including fibrous forage, granular or powdered concentrates, enter the mixing chamber. The spiral conveying blades of the conveying auger propel the materials forward and mix them. Simultaneously, the cutter cuts the materials. However, as the materials move, powders and granules gradually sink to the bottom of the receiving tank. At this point, due to the contact between the elastic lifting section and the tank wall, the cut materials enter the lower part of the lifting section. The lifting section is already in contact with the wall of the receiving trough, so the material falls onto the lifting section. As the screw conveyor blades rotate, the lifting section carries the material and gradually rises. During this ascent, some of the material on the lifting section slowly falls back down, mixing with other materials. After lifting the material, the lifting section rotates again and faces downwards. At this point, because the lifting section is made of elastic material, it can elastically compress the loose material at the bottom of the receiving trough. The loose material is compressed and moves, causing the lifting section to gradually contact the wall of the receiving trough, thus carrying the loose material again and forming a lifting cycle. From the above working process, it is easy to see that this application, through a simple structural modification of the existing screw conveyor blades, can significantly improve the effect of lifting the bottom loose material for thorough mixing, making the prepared feed more uniform and ensuring more balanced nutrition.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] An embodiment of the multi-inclined-plane shear feed mixer of this utility model: (e.g.) Figure 1-6 As shown, this mixer is mainly used for shearing, mixing and preparing feed, and mainly includes a support frame 1, a mixing chamber 2, a motor mounting frame 24, a motor 25 and a transmission mechanism 26, a conveying auger 3, and a lifting screw belt 4, etc.

[0031] like Figure 1 As shown, the support frame 1, mixing chamber 2, and motor mounting bracket 24 are an integral welded structure or a bolted connection structure. The support frame 1 includes four legs. The mixing chamber 2 is rectangular in shape, with a feed inlet 22 located in the middle of one side along its length. The lower end of the feed inlet 22 is hinged to the mixing chamber 2, and the upper end is connected by a chain or rope. The feed inlet 22 can be opened and closed. Figure 1 In its open state, it can serve as a temporary support 1 for material feeding. The discharge port 23 of the mixing chamber 2 is located in the lower central area on one side of the width direction, corresponding to the middle of the conveying auger 3, and the discharge port 23 is also equipped with a corresponding opening and closing door. The motor mounting bracket 24 is located on the other side of the length direction of the mixing chamber 2, that is, on the side away from the feed port 22. The motor mounting bracket 24 has a U-shaped tray structure and is used to support and install the motor 25 and transmission mechanism 26, etc. Two receiving slots 21 are symmetrically arranged side by side along the width direction at the bottom of the mixing chamber 2, and the length of the receiving slots 21 extends along the length direction of the mixing chamber 2. Figure 3 As shown, the shape of the receiving hopper can be considered as a semi-polygonal structure formed by bending a flat plate multiple times, essentially semi-enclosing the lower part of the conveying auger 3. The motor 25 can be a geared motor, and the transmission mechanism 26 can be a gear drive or a sprocket drive. The rotating shafts 31 of the two conveying augers 3 are driven by the same motor through the transmission mechanism 26. Generally, the two conveying augers 3 use the same transmission ratio to ensure synchronous rotation. However, for some special purposes, the two conveying augers 3 can be driven by the same motor but with different transmission ratios, meaning the two conveying augers 3 can rotate at different speeds. Of course, two motors can also be used to drive the two conveying augers 3 separately. The bottom of the receiving trough 21 has a multi-sloping spliced ​​structure. The multi-sloping structure allows the receiving trough 21 to be directly formed by bending steel plates, making processing easier. Furthermore, due to the different inclination angles of each slope, when the lifting section 41 contacts adjacent slopes sequentially from below, the steeper inclination angle of the next slope makes it easier for nearby loose material to fall onto the lifting section 41, thus improving the mixing effect. Two receiving troughs 21 are symmetrically arranged side-by-side within the mixing chamber 2. The conveying auger 3 and the corresponding lifting spiral belt 4 are respectively installed in the two receiving troughs 21. Each conveying auger 3 has two symmetrically arranged spiral conveying blades 32 with opposite spiral directions. This design allows material on both sides to move towards the center along the axial direction of the rotating shaft 31. When more material accumulates in the center, it can tumble towards both sides, resulting in better mixing of materials and facilitating multiple cuts of fibrous materials, leading to more uniform cutting.

[0032] The conveying auger 3 consists of a rotating shaft 31 and two symmetrically arranged spiral conveying blades 32 on the rotating shaft 31. The two spiral conveying blades 32 rotate in different directions, one left-handed and the other right-handed. This arrangement allows materials on both sides to move towards the center, then accumulate in the center and tumble to both sides, improving the mixing effect. Simultaneously, since the discharge port 23 is located in the center, this arrangement also facilitates rapid discharge. The two ends of the rotating shafts 31 of the two conveying augers 3 are rotatably mounted to the two ends of the mixing chamber 2 via bearings, and are located in two receiving troughs 21 respectively. The rotating shafts 31 are parallel to the bottom of the receiving troughs 21. The spiral conveying blades 32 are spiral plates made of steel plates, welded and fixed to the outer circumference of the rotating shaft 31. Near the outer edge of the spiral conveying blades 32, there are welded or bolted quincunx-shaped blades (not shown in the diagram), i.e., cutters, used to cut fibrous materials. Multiple cutters are spaced apart along the extension direction of the spiral conveying blades 32.

[0033] like Figure 2-6 As shown, the lifting spiral belt 4 is fixed spirally on the outer edge of the spiral conveyor blade 32, including two lifting sections 41. The two lifting sections extend outward from the sides of the spiral conveyor blade 32, respectively. The lifting sections 41 are made of elastic material, and their outer surfaces can elastically contact the wall of the receiving trough 21. The lifting sections have an arc-shaped spiral ribbon structure. Compared to a flat surface, the arc-shaped spiral ribbon structure of the lifting sections has a certain degree of effect in containing and holding loose materials. Because the arc shape is a concave structure, it can improve the containing and holding effect, delaying the material's fall and thus lifting the loose materials higher, further improving the mixing effect and making the mixing more uniform. The outer edge of the lifting section 41 has chamfered portions 411 with progressively decreasing thickness. By setting chamfered portions 411 with progressively decreasing thickness, the outer edge of the lifting portion 41 can more easily pass through the loose material and fit against the wall of the receiving tank 21, or in other words, it is easier for the loose material in the receiving tank 21 to enter the lifting portion 41, thereby increasing the amount of loose material that can be lifted and thus improving the mixing effect.

[0034] In this embodiment, the lifting spiral belt is made of rubber and is fixed to the spiral conveyor blade 32 by vulcanization. This structure requires no further installation and is more robust and reliable. In other embodiments, the lifting spiral belt 4 includes a U-shaped metal skeleton and the lifting section 41 vulcanized on the metal skeleton. Multiple bolt holes are correspondingly provided on the metal skeleton and the spiral conveyor blade 32, spaced apart along their length, to fix the metal skeleton relative to the spiral conveyor blade 32. This structure improves the overall strength and rigidity of the lifting spiral belt 4 and facilitates the connection with the spiral conveyor blade 32 using bolt holes. The lifting spiral belt 4 is composed of multiple arc-shaped segments spliced ​​together. This structure not only facilitates the production, transportation, and disassembly of the lifting spiral belt 4 but also helps reduce various costs. When the lifting spiral belt 4 rotates with the spiral conveyor blade 32, the lifting section can lift the settled material in the receiving trough 21 and mix it with other materials.

[0035] In use, this multi-inclined-plane shear feed mixer allows materials of various shapes, densities, and diameters, including fibrous forage and granular or powdered concentrates, to enter the mixing chamber 2. The spiral conveying blades 32 of the conveying auger 3 propel these materials forward and mix them. Simultaneously, a cutter cuts the materials. However, as the materials move, powders and granules gradually sink to the bottom of the receiving trough 21. At this point, the elastic lifting section 41 contacts the wall of the receiving trough 21, ensuring that the lower part of the lifting section 41 adheres to the receiving trough 21 before the material enters. The material falls onto the lifting section 41 as the screw conveyor blades 32 rotate. As the lifting section 41 carries the material, it gradually rises. During this ascent, some of the material on the lifting section 41 slowly falls back down, mixing with other materials. After lifting, the lifting section 41 rotates again and faces downwards. Because the lifting section 41 is made of elastic material, it can elastically compress the loose material at the bottom of the receiving trough 21. The compressed material moves, causing the lifting section 41 to gradually contact the trough wall of the receiving trough 21, thus re-carrying the loose material and forming a lifting cycle. From the above process, it is clear that this application, through a simple structural modification of the existing screw conveyor blades 32, can significantly improve the effect of lifting and mixing the settled loose material, resulting in more uniform feed and ensuring more balanced nutrition.

Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
