Description

Technical Field

[0001] The invention relates to the field of feed preparation, and in particular to a mixing feeding device for preparing biomass feed. Background Art

[0002] Biomass feed usually contains raw materials from various sources (such as Caragana korshinskii, Salix psammophila, straw, alfalfa, etc.) and additives (such as minerals, vitamins, trace elements, etc.). The properties, particle sizes and specific gravity of these ingredients vary greatly. If they are not mixed evenly, the concentration of certain nutrients in the feed may be too high or too low, affecting the health and growth of animals. By mixing, it is ensured that each portion of feed can provide balanced nutrients, thereby improving the effect of the feed.

[0003] In the current mixing process, raw materials are transported to the mixer through an elevator, but during the transportation process, the raw materials often experience stratification, agglomeration or compaction, especially in raw materials with large differences in particle size. This problem is particularly prominent. In addition, during the mixing of raw materials, trace element powders (such as mineral powders, vitamins, etc.) need to be added. However, due to the light weight of trace element powders, they are easily stratified with heavier raw materials during transportation, resulting in the trace element powders not being evenly distributed in the raw materials. This separation phenomenon prevents the trace elements from effectively attaching to other raw materials, thereby affecting the uniformity of the final mixing, and further affecting the nutritional balance and quality of the feed. Summary of the invention

[0004] In order to overcome the shortcomings that in the current mixing process, when the raw materials are transported to the mixer through the elevator, stratification, agglomeration or compaction is prone to occur, and the trace element powder is light in weight and easily stratified with the heavier raw materials, resulting in inability to adhere evenly, affecting the mixing uniformity, thereby affecting the nutritional balance and quality of the feed. In order to solve the above-mentioned problems, a mixing feeding device for biomass feed preparation is now provided. In the process of transporting the raw materials to the mixer, the raw materials can be preliminarily mixed and broken up during the transportation process to prevent stratification, agglomeration or accumulation, and ensure that raw materials of different particle sizes are evenly distributed; at the same time, the trace element powder is gradually added in the initial stage of transportation, and the trace element powder can be evenly attached to the surface of the raw materials during the transportation movement.

[0015] 2. The reciprocating up and down motion of the guide rod drives the rack and the push frame to move up and down together. The push frame further drives the iron frame to move up and down. With the help of the guide groove, the iron frame pushes the push block to move in the trough, so that the trace element powder additive is gradually and evenly fed into the raw material. This process effectively avoids the problem that the trace element powder cannot be evenly attached to the raw material due to its light weight, and significantly improves the quality and effect of feed mixing.

[0016] 3. The guide rod drives the driving protrusion to move up and down, and the driving protrusion moves up and down to drive the knocking rod to knock and vibrate repeatedly, which can effectively prevent the powder from being blocked in the material tube and ensure that the trace element powder can flow smoothly into the raw material. This vibration can not only break up the lumps that may be formed, but also reduce the deposition of trace element powder in the material tube, ensuring the accurate addition of trace elements in each batch of feed and improving the mixing effect and quality of the feed.

The mixer 2 is installed on one side of the base frame 1, and the feeding barrel 3 is installed on the other side of the base frame 1. The hopper 4 is installed at the lower part of the feeding barrel 3, and the hopper 4 is connected with the feeding barrel 3. The base frame 1 and the feeding barrel 3 are provided with a feeding device, and the feeding device is used to transport the raw materials into the mixer 2. The feeding barrel 3 is provided with a preliminary mixing mechanism, and the preliminary mixing mechanism is used to preliminarily mix the raw materials.

[0039] The feeding device includes a hollow cylinder 51, a spiral blade 52, a reduction motor 53 and a transmission assembly 54. The hollow cylinder 51 is rotatably provided on the feeding cylinder 3 through a bearing. A spiral blade 52 for conveying raw materials is installed in the middle of the hollow cylinder 51. The spiral blade 52 is located in the feeding cylinder 3. The reduction motor 53 is installed on the base frame 1. The transmission assembly 54 is connected between the output shaft of the reduction motor 53 and the hollow cylinder 51.

[0040] The primary mixing mechanism includes a primary mixing frame 61, a gear 62, a guide frame 63, a guide rod 64, a rack 65, a corrugated groove drum 66, a connecting frame 67 and a roller 68. A plurality of primary mixing frames 61 for breaking up the raw materials are rotatably provided on the hollow cylinder 51 through bearings. A gear 62 is installed at one end of each primary mixing frame 61 located at the hollow cylinder 51. A guide frame 63 is installed on both upper and lower sides of the hollow cylinder 51. A guide rod 64 is slidably provided between the two guide frames 63. A plurality of racks 65 are provided on the guide rod 64. Each rack 65 is respectively engaged with each gear 62. A corrugated groove drum 66 is fixedly installed at the bottom of the feeding barrel 3. A corrugated groove is opened on the corrugated groove drum 66. A connecting frame 67 is fixedly installed at the lower end of the guide rod 64. A roller 68 is rotatably provided on the connecting frame 67. The roller 68 is located in the corrugated groove on the corrugated groove drum 66.

[0041] A protection frame 7 is also included. The protection frame 7 is installed at the bottom of the base frame 1. The reduction motor 53, the transmission assembly 54, the guide rod 64, the corrugated groove cylinder 66 and the connecting frame 67 are all located in the protection frame 7.

[0042] The operator starts the mixer 2 first, then continuously supplies raw materials into the hopper 4, and then starts the output shaft of the reduction motor 53 to rotate. The output shaft of the reduction motor 53 drives the hollow cylinder 51 and the spiral blade 52 to rotate through the transmission component 54. The spiral blade 52 can transport the raw materials in the hopper 4 to the upper part of the feeding barrel 3. The raw materials are discharged from the upper part of the barrel into the mixer 2 for mixing. When the hollow cylinder 51 rotates, it drives the primary mixing frame 61, the gear 62, the guide frame 63, the guide rod 64, the rack 65, the connecting frame 67 and the roller 68 to rotate. The roller 68 will rotate along the corrugated groove cylinder 66. The corrugated groove of the corrugated groove cylinder 66 moves. Under the action of the corrugated groove on the corrugated groove cylinder 66, the roller 68, the connecting frame 67, the guide rod 64 and the rack 65 will continuously move up and down. The guide frame 63 guides the guide rod 64. The rack 65 moves up and down to drive the gear 62 to rotate forward and reversely. The forward and reverse rotation of the gear 62 drives the primary mixing frame 61 to continuously rotate forward and reversely. In the process of the spiral blade 52 conveying the raw materials in the hopper 4 to the upper part of the feeding barrel 3, the primary mixing frame 61 continuously rotates forward and reversely to break up and preliminarily mix the raw materials to avoid stratification, agglomeration or compression of the raw materials during the conveying process. In this way, the raw materials are fully loosened and mixed during the conveying and preliminarily mixing process, thereby improving the efficiency of feed preparation; after the feed is mixed, the operator turns off the mixer 2 and the reduction motor 53.

[0043] The transmission assembly 54 is composed of two pulleys and a flat belt. The two pulleys are respectively mounted on the output shaft of the reduction motor 53 and the hollow cylinder 51, and a flat belt is wound between the two pulleys.

[0044] The protection frame 7 can shield the reduction motor 53 , the transmission assembly 54 , the guide rod 64 , the corrugated groove cylinder 66 and the connecting frame 67 , and prevent debris from being drawn into the reduction motor 53 , the transmission assembly 54 , the guide rod 64 , the corrugated groove cylinder 66 and the connecting frame 67 .

[0045] Embodiment 2: Based on embodiment 1, Figure 9-Figure 15 As shown, it also includes a discharging mechanism, which is arranged on the feeding barrel 3, the hollow cylinder 51, the primary mixing frame 61 and the guide rod 64. The discharging mechanism is used to add trace element powder when the raw materials are transported and pre-mixed. The discharging mechanism includes a coupling frame 81, a charging barrel 82, a cover 83, a material pipe 85, a circular baffle 86, a pushing block 87, a horizontal shaft 88, an iron frame 89, a magnet block 810 and a pushing frame 811. The coupling frame 81 is installed on the top of the feeding barrel 3. A loading barrel 82 for storing trace element powder is installed on the coupling frame 81, and a cover 83 is provided on the upper part of the loading barrel 82. A material trough 84 is opened on the hollow cylinder 51, and an outlet is provided on the material trough 84. A material pipe 85 is embedded in the hollow cylinder 51. One end of the material pipe 85 is rotatably connected to the lower part of the loading barrel 82 through a sealed bearing, and the other end of the material pipe 85 is located in the material trough 84. The loading barrel 82 and the material trough 84 are connected through the material pipe 85. A circular baffle 86 is fixedly installed on the primary mixing frame 61 near the material trough 84, and the circular baffle 86 is tightly fitted with the side of the hollow cylinder 51. The circular baffle 86 blocks the outlet on the material trough 84, and a discharge port 861 is opened on the circular baffle 86. A pushing block 87 is slidably provided at the lower part of the material trough 84, and two horizontal shafts 88 are rotatably provided on both sides of the pushing block 87. An iron frame 89 is slidably provided in the hollow cylinder 51, and the iron frame 89 will slide up and down along the hollow cylinder 51. A guide groove 891 is opened on both sides of the iron frame 89, and the two horizontal shafts 88 are respectively located in the two guide grooves 891. Two magnet blocks 810 are fixedly installed in the hollow cylinder 51 by bolts, and the iron frame 89 is located between the two magnet blocks 810. The iron frame 89 is adsorbed by one of the magnet blocks 810. A pushing frame 811 is fixedly installed on the guide rod 64, and the pushing frame 811 contacts one of the surfaces on the upper part of the iron frame 89.

[0046] The guide groove 891 consists of a short straight groove, an inclined groove and a long straight groove, and the transverse axis 88 is located in the short straight groove of the guide groove 891.

[0047] The operator opens the lid 83, loads an appropriate amount of trace element powder additives into the loading barrel 82, and then covers the loading barrel 82 with the lid 83. The trace element powder additives in the loading barrel 82 enter the material trough 84 through the material pipe 85. Initially, the circular baffle 86 blocks the outlet on the material trough 84, and the guide rod 64 drives the rack 65 and the push frame 811 to move up and down. When the guide rod 64 drives the rack 65 and the push frame 811 to move upward, the upper part of the push frame 811 is separated from the upper top of the iron frame 89, and the rack 65 drives the gear 62 and the primary mixing frame 61 to rotate, and the primary mixing frame 61 drives the circular baffle 86 to rotate. After the discharge port 861 on the circular baffle 86 coincides with the outlet on the material trough 84, the lower part of the push frame 811 just contacts the upper bottom of the iron frame 89, and the guide rod 64 drives the rack 65 and the push frame 811 to move upward. The frame 811 continues to move upward, and the push frame 811 will push the iron frame 89 and the guide groove 891 to move upward, and the lower bottom of the iron frame 89 will be separated from the magnet block 810 below. The two short straight grooves on the guide groove 891 will move and separate from the two horizontal axes 88. The two inclined grooves on the guide groove 891 will move to the two horizontal axes 88. Under the action of the two inclined grooves on the guide groove 891, the two horizontal axes 88 and the pusher block 87 will move in the direction away from the guide rod 64, and the pusher block 87 can push the trace element powder additive in the trough 84 into the raw material. After the pusher block 87 moves in the direction away from the guide rod 64, the end face of the pusher block 87 is exactly flush with the side of the hollow cylinder 51. When the two long straight grooves on the guide groove 891 move to the two horizontal axes 88, the top of the iron frame 89 is just adsorbed by the magnet block 810 above.When the guide rod 64 drives the rack 65 and the push frame 811 to move downward, the lower part of the push frame 811 is separated from the upper bottom of the iron frame 89, the rack 65 drives the gear 62 and the primary mixing frame 61 to rotate in the opposite direction, and the primary mixing frame 61 drives the circular baffle 86 to rotate in the opposite direction, and the circular baffle 86 can block the outlet on the trough 84 again. At this time, the upper part of the push frame 811 just contacts the upper top of the iron frame 89, and the guide rod 64 drives the rack 65 and the push frame 811 to continue to move downward, and the push frame 811 will push the iron frame 89 and the guide slot 891 downward, the upper top of the iron frame 89 will be separated from the upper magnet block 810, the two long straight slots on the guide slot 891 will move and separate from the two horizontal shafts 88, and the two inclined slots on the guide slot 891 will move to the two horizontal shafts 88. Under the action of the two inclined slots on the guide slot 891, the two horizontal shafts 88 and the push block 87 will move toward the direction close to the guide rod 64. At this time, the round baffle 86 blocks the outlet of the trough 84, so , when the push block 87 moves toward the direction close to the guide rod 64, the raw material will not enter the trough 84. Under the action of gravity, the trace element powder additive will fall and fill the trough 84 again, so that the push block 87 can push out the trace element powder additive next time. When the two short straight grooves on the guide groove 891 move to the two horizontal axes 88, the bottom of the iron frame 89 is just adsorbed by the magnet block 810 below. This is repeated. While conveying, preliminarily mixing and breaking up the raw materials, the guide rod 64 reciprocates up and down, driving the rack 65 and the push frame 811 to move up and down together. The push frame 811 further drives the iron frame 89 to reciprocate up and down. With the help of the guide groove 891, the iron frame 89 pushes the push block 87 to move in the trough 84, so that the trace element powder additive is gradually and evenly fed into the raw material. This process effectively avoids the problem that the trace element powder cannot be evenly attached to the raw material due to its light weight, and significantly improves the quality and effect of feed mixing. ;

[0048] Embodiment 3: Based on embodiment 2, Figure 16-Figure 19 As shown, it also includes a vibration mechanism, which is arranged on the hollow cylinder 51 and the guide rod 64. The vibration mechanism is used to vibrate the material tube 85. The vibration mechanism includes an articulated seat 91, a knocking rod 92, a torsion spring 93, a driving protrusion 94 and a reset spring 95. A plurality of articulated seats 91 are evenly installed on one side of the hollow cylinder 51. A knocking rod 92 for knocking the side wall of the hollow cylinder 51 is rotatably provided on each articulated seat 91 through a bearing. One end of the knocking rod 92 contacts the side of the hollow cylinder 51 that passes through the material tube 85. A torsion spring 93 is respectively connected between the two sides of the knocking rod 92 and the two sides of the articulated seat 91. A plurality of driving protrusions 94 are evenly spaced and slidably provided on the guide rod 64. Two reset springs 95 are connected between each driving protrusion 94 and the guide rod 64. Each driving protrusion 94 is provided with an arc surface and an inclined surface. The arc surface on each driving protrusion 94 contacts the other end of each knocking rod 92.

[0049] A rubber ball 10 is also included. A rubber ball 10 is installed at one end of each knock rod 92 close to the inner side of the hollow cylinder 51.

[0050] The guide rod 64 drives the driving protrusion 94 to move up and down. When the driving protrusion 94 moves upward, the arc surface on the driving protrusion 94 will contact one end of the knocking rod 92. Under the action of the arc surface on the driving protrusion 94, the knocking rod 92 will swing, and the other end of the knocking rod 92 will separate from the side of the hollow cylinder 51 that passes through the material tube 85, and the torsion spring 93 will twist accordingly. When the driving protrusion 94 is separated from one end of the knocking rod 92, under the action of the torsion spring 93, the other end of the knocking rod 92 will knock on the side of the hollow cylinder 51 that passes through the material tube 85, which can cause the material tube 85 to vibrate. When the driving protrusion 94 moves downward, after one end of the knocking rod 92 contacts the inclined surface on the driving protrusion 94, the driving protrusion 94 will move away from the guide rod 64 and reset. The spring 95 stretches accordingly, and when one end of the knocking rod 92 moves to contact the arc surface on the driving protrusion 94 again, under the action of the reset spring 95, the driving protrusion 94 will move and reset in the direction close to the guide rod 64, and repeat this process. The other end of the knocking rod 92 will repeatedly knock on the side of the hollow cylinder 51 that passes through the material tube 85, which can cause the material tube 85 to vibrate. The repeated knocking and vibration of the knocking rod 92 can effectively prevent the powder from being blocked in the material tube 85, and ensure that the trace element powder can flow smoothly into the raw material. This vibration can not only break up the lumps that may be formed, but also reduce the deposition of the trace element powder in the material tube 85, thereby ensuring the accurate addition of trace elements in each batch of feed and improving the mixing effect and quality of the feed.

[0051] Under the action of the rubber ball 10, the impact force generated when the knocking rod 92 knocks the hollow cylinder 51 can be effectively buffered, thereby avoiding damage to the hollow cylinder 51 caused by direct impact. The rubber ball 10, as a buffer medium, can reduce the transmission of the knocking force, protect the structural integrity of the hollow cylinder 51 and the material tube 85, and extend the service life of the equipment.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
