Description

Technical Field

[0001] The invention relates to the technical field of feed feeding, in particular to a feeding port for a feed production line. Background Art

[0002] Feed is the general term for the food needed by all artificially raised animals. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. At the same time, with the improvement of economic level, people's pursuit of material life continues to improve, so the amount of feed used for breeding is also increasing every year.

[0003] During the feed preparation process, the raw materials need to be fed into the feeding barrel from the feeding port. When the raw materials pass through the feeding port, they need to be filtered and dispersed by a screening plate (generally a grid). However, when a large amount of materials are fed, a large amount of raw materials are accumulated on the top surface of the screening plate, which is easy to spill on the bottom surfaces on both sides of the leakage port, causing waste. In addition, the screening plate is usually set statically, and the filtering and dispersing efficiency of the raw materials is poor. At the same time, when the feeding port is not in use, it is generally set in an open manner, which makes it easy for debris and pests to enter, causing cross contamination to the raw materials. Therefore, the present invention provides a feeding port for a feed production line to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a feeding port for a feed production line.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The swing-type screening assembly comprises a rotating shaft rotatably mounted on the axis of the sealing plate, a screening plate is fixedly sleeved on the outer wall of the rotating shaft, and the screening plate is slidably fitted to the inner surface of the screening tank, a driving gear is rotatably mounted on the outer surface of the screening tank through a driving shaft, a transition gear is meshed on the outer side of the driving gear, an incomplete gear rotatably mounted on the surface of the screening tank is arranged on the outer side of the transition gear, the incomplete gear is meshed or separated with the driving gear transition gear, a right angle frame is fixedly mounted on the surface of the screening tank, and a driving motor for driving the incomplete gear is fixedly mounted on the other end of the right angle frame;

[0009] Preferably, the dustproof assembly includes two rotating shafts symmetrically rotatably installed in the feed hopper, the outer wall of each rotating shaft is fixedly sleeved with a dustproof plate, and the dustproof plate slides in contact with the inner surface of the feed hopper, and a pinion is fixedly installed at one end of the two rotating shafts located outside the feed hopper, a coil spring is commonly connected between each of the pinion gears and the corresponding rotating shaft, and racks are meshed on opposite sides of the two pinions, a sliding limit assembly is provided between the two racks and the screening tank, and a magnetic plate is commonly fixedly installed between the two racks, an electromagnet is provided under the magnetic plate, and the electromagnet is fixedly installed on the surface of the screening tank.

[0010] Preferably, the clamping assembly comprises a rectangular clamping block fixedly mounted on one end of the rotating shaft away from the sealing plate, and the rectangular clamping block is clamped or separated from the driving shaft, and a rectangular clamping groove matching the rectangular clamping block is formed at the end of the driving shaft.

[0011] Preferably, a mounting frame is fixedly mounted on the outer side of the discharge pipe, and a plurality of mounting holes are formed on the surface of the mounting frame.

[0012] Preferably, the sliding limit assembly comprises a dovetail bar slidably connected to the surface of the rack, and the dovetail bar is fixedly mounted on the surface of the screening tank, and the end of the rack is provided with a dovetail groove slidably connected to the dovetail bar.

[0013] Preferably, limit strips are fixedly mounted on the surfaces of the two pinions, and the inner sides of the limit strips are in contact with or separated from the outer surface of the sealing plate.

[0014] Preferably, a plurality of plug-in blocks are fixedly mounted on the surface of the sealing plate, and the plug-in blocks are slidably inserted at the rear end of the screening tank, and a plurality of slots matching the plug-in blocks are provided on the rear side of the screening tank.

[0015] Compared with the existing technology, the advantages of the feed inlet for a feed production line provided by the present invention are:

[0016] 1. The motor drives the intermittent staggered meshing of the incomplete gear with the driving gear and the transition gear, and the driving gear and the transition gear are always meshed. Under the continuous rotation of the incomplete gear, the reciprocating swing of the screening plate can be realized through the driving shaft, thereby playing a shaking role on the surface of the screening plate, so as to improve the filtering and dispersion efficiency of the feed raw materials;

At the same time, at the beginning and end of feeding, the upper port of the feeding hopper can be automatically opened and closed, thereby effectively preventing debris and pests from entering when not in use, so as to avoid cross contamination of the raw materials.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figures 1 to 6A feeding port for a feed production line includes a screening tank 1. The top and bottom of the screening tank 1 are respectively fixedly connected with a feed hopper 2 and a discharge pipe 25. A mounting frame 23 is fixedly installed on the outer side of the discharge pipe 25. A plurality of mounting holes 24 are opened on the surface of the mounting frame 23. When in use, the mounting frame 23 can be fixed on the production line by using a plurality of screws to pass through the plurality of mounting holes 24 in sequence, thereby completing the connection and fixation between the device and the production line.

[0029] The rear side of the screening tank 1 is open and equipped with a sealing plate 3, and a swing-type screening assembly is provided between the sealing plate 3 and the screening tank 1; the swing-type screening assembly includes a rotating shaft 4 rotatably mounted on the axis of the sealing plate 3, and a screening plate 5 is fixedly sleeved on the outer wall of the rotating shaft 4, and the screening plate 5 is slidably fitted to the inner surface of the screening tank 1, and a driving gear 8 is rotatably mounted on the outer surface of the screening tank 1 through a driving shaft 7, and a transition gear 10 is meshed on the outer side of the driving gear 8, and an incomplete gear 11 rotatably mounted on the surface of the screening tank 1 is provided on the outer side of the transition gear 10, and the incomplete gear 11 is meshed or separated with the driving gear 8 and the transition gear 10, and a right-angle frame 12 is fixedly mounted on the surface of the screening tank 1, and a driving motor 13 for driving the incomplete gear 11 is fixedly mounted on the other end of the right-angle frame 12. When in use, the feed raw material is put into the feed hopper 2 At the same time, the driving motor 13 is started to drive the incomplete gear 11 to rotate clockwise. When the incomplete gear 11 is meshed with the driving gear 8, the driving gear 8 can be driven to rotate counterclockwise. When the incomplete gear 11 is not meshed with the driving gear 8, it starts to mesh with the transition gear 10 and drives the transition gear 10 to rotate counterclockwise. At this time, the transition gear 10 will drive the driving gear 8 to rotate clockwise, that is, whenever the incomplete gear 11 is meshed with the driving gear 8, the driving gear 8 will rotate counterclockwise. When the incomplete gear 11 is not meshed with the driving gear 8, the driving gear 8 will rotate clockwise. Therefore, under the continuous rotation of the incomplete gear 11, the reciprocating swing of the screening plate 5 can be realized through the driving shaft 7, so as to play a shaking role on the surface of the screening plate 5, so as to improve the filtering and dispersion efficiency of the feed raw materials.

[0030] A dustproof assembly is provided at the top of the feed hopper 2, and the dustproof assembly includes two rotating shafts 14 symmetrically rotatably installed in the feed hopper 2, and the outer wall of each rotating shaft 14 is fixedly sleeved with a dustproof plate 16, and the dustproof plate 16 slides and fits on the inner surface of the feed hopper 2, and a pinion 15 is fixedly installed at one end of the two rotating shafts 14 located outside the feed hopper 2, and a coil spring 17 is commonly connected between each pinion 15 and the corresponding rotating shaft 14, and a rack 18 is meshed on the opposite sides of the two pinions 15, and a sliding limit assembly is provided between the two racks 18 and the screening tank 1, and the sliding limit assembly includes a dovetail bar 21 slidably connected to the surface of the rack 18, and the dovetail bar 21 is fixedly installed on the surface of the screening tank 1, and a dovetail groove slidably connected to the dovetail bar 21 is opened at the end of the rack 18, and the dovetail groove and the dovetail bar 21 are limited and engaged, so that the rack 18 can maintain vertical movement.

[0031] A magnetic plate 19 is fixedly installed between the two racks 18, and an electromagnet 20 is provided below the magnetic plate 19, and the electromagnet 20 is fixedly installed on the surface of the screening tank 1. When the device is powered on, the electromagnet 20 is energized to repel the magnetic plate 19 from moving upward, driving the two racks 18 to move upward, and then driving the two pinions 15 meshing with each other to rotate in the opposite direction, and causing the coil spring 17 to deform, so that the two dustproof plates 16 can be turned over by the two rotating shafts 14 to open the upper port of the feed hopper 2 (refer to Figure 4 ), on the contrary, when not in use, the external power supply of the device is disconnected, at this time, under the elasticity of the coil spring 17, the two small gears 15 are reversed and reset until the two dustproof plates 16 are driven to reset, so that the upper port of the feed hopper 2 can be sealed, so that the feeding port on the production line can be sealed when not in use, which can effectively prevent debris and pests from entering, so as to avoid cross contamination of raw materials.

[0032] A clamping assembly is provided between the driving shaft 7 and the rotating shaft 4, and the clamping assembly includes a rectangular clamping block 6 fixedly installed on the end of the rotating shaft 4 away from the sealing plate 3, and the rectangular clamping block 6 is clamped or separated from the driving shaft 7, and a rectangular clamping groove 9 matching the rectangular clamping block 6 is provided at the end of the driving shaft 7, and a plurality of plug-in blocks 26 are fixedly installed on the surface of the sealing plate 3, and the plug-in block 26 is slidably inserted at the rear end of the screening tank 1, and a plurality of slots matching the plug-in blocks 26 are provided on the rear side of the screening tank 1. The plug-in cooperation between each plug-in block 26 and the corresponding slot can play a role in preliminary positioning of the sealing plate 3, and after the screening plate 5 is inserted into the screening tank 1, the driving shaft 7 and the screening plate 5 can be rotated synchronously through the clamping between the rectangular clamping block 6 and the rectangular clamping groove 9 on the driving shaft 7.

[0033] Furthermore, the surfaces of the two pinions 15 are fixedly mounted with limit strips 22, and the inner side of the limit strips 22 is in contact with or separated from the outer surface of the sealing plate 3. After the device is connected to an external power supply, the two pinions 15 rotate to drive the two dustproof plates 16 to flip. At this time, the two limit strips 22 approach each other until they are in contact with the surface of the sealing plate 3, thereby limiting the sealing plate 3 (refer to Figure 4 ), on the contrary, after the power is disconnected, the two dustproof plates 16 are sealed, and the two limit strips 22 rotate in opposite directions and no longer block the sealing plate 3, so the sealing plate 3 can be pulled out to clean and maintain the screening plate 5 to ensure the filtering effect of the screening plate 5.

[0034] The working principle of the present invention is:

[0035] When in use, first turn on the power of the device, the electromagnet 20 is energized to repel the magnetic plate 19 to move upward, driving the two racks 18 to move upward, and then driving the two pinions 15 meshing with them to rotate in the opposite direction, and causing the coil spring 17 to deform, so that the two dust-proof plates 16 can be flipped through the two rotating shafts 14 to open the upper port of the feed hopper 2 (refer to Figure 4 );

[0036] Subsequently, the feed material is put into the feed hopper 2. At the same time, the driving motor 13 is started to drive the incomplete gear 11 to rotate clockwise. When the incomplete gear 11 is meshed with the driving gear 8, the driving gear 8 can be driven to rotate counterclockwise. When the incomplete gear 11 is not meshed with the driving gear 8, it starts to mesh with the transition gear 10 and drives the transition gear 10 to rotate counterclockwise. At this time, the transition gear 10 will drive the driving gear 8 to rotate clockwise, that is, whenever the incomplete gear 11 is meshed with the driving gear 8, the driving gear 8 will rotate counterclockwise. When the incomplete gear 11 is not meshed with the driving gear 8, the driving gear 8 will rotate clockwise. Therefore, under the continuous rotation of the incomplete gear 11, the reciprocating swing of the screening plate 5 can be realized through the driving shaft 7, so as to play a shaking role on the surface of the screening plate 5, so as to improve the filtering and dispersion efficiency of the feed material;

[0037] Finally, after the feeding is completed, the external power supply of the device is disconnected. At this time, under the elasticity of the coil spring 17, the two pinions 15 are reversed and reset until the two dustproof plates 16 are driven to reset, so that the upper port of the feed hopper 2 can be sealed, so that the feeding port on the production line can be sealed when not in use, which can effectively prevent debris and pests from entering, so as to avoid cross contamination of the raw materials;

[0038] At the same time, after the two dustproof plates 16 are turned over to seal the upper port of the feed hopper 2, the two limit bars 22 will also rotate in opposite directions, no longer blocking the sealing plate 3, and the sealing plate 3 can be pulled out to clean and maintain the screening plate 5.

[0039] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
