Abstract
Description
Technical Field
[0001] This application relates to the field of poultry farming equipment, and in particular to a feeding auger screen device. Background Technology
[0002] Stacked cage rearing equipment is a key intensive equipment in large-scale poultry and livestock farming (such as chickens and ducks). Its core function is to solve the pain points of low space utilization, poor management efficiency and difficulty in environmental control in the traditional floor rearing mode through scientific three-dimensional space planning and standardized management, and promote the transformation of the breeding process towards high efficiency and standardization.
[0003] The stacked cage rearing equipment is equipped with a feeding device. This device uses a feeding screw via a feeding auger to transport feed from the hopper to the batching device, which then systematically dispenses feed into the troughs, automating the feeding process for poultry and livestock. In practical applications, due to vibration or compression during production or transportation, some feed particles may break. After the feed is fed into the hopper, the feeding screw transports it to the batching device, which directly dispenses the feed into the troughs. The broken feed particles are simultaneously conveyed into the troughs.
[0004] However, the problem is that because the incomplete feed is relatively small, it is not easy for poultry to eat. The small feed particles that are difficult to eat will accumulate at the bottom of the feed trough. After the small feed particles get damp, they will clump together. Therefore, it is necessary to clean the clumps of small feed particles in the feed trough regularly, resulting in feed waste. There is room for improvement. Utility Model Content
[0005] The purpose of this utility model is to provide a feeding auger sieve device in order to reduce the amount of small feed particles that accumulate at the bottom of the feed trough.
[0006] To achieve the above objectives, the feeding auger screening device provided in this application adopts the following technical solution:
[0007] A feeding auger screening device includes a screening box, a feeding channel and a feeding pipe on the screening box, a feeding screw rotating through the feeding pipe, a feeding hole on the feeding pipe, and a screening screen on the screening box located at the feeding hole.
[0008] Preferably, the screening box is provided with a cover, the cover covers the screening box, and the cover has a limiting opening, the outline of which is adapted to the outline of the feed tube.
[0009] Preferably, a limiting platform is provided on the screening box, and the screening screen is disposed on the limiting platform. When the material conveying pipe is disposed on the screening screen, the material conveying pipe abuts against the surface of the screening screen, and the material conveying hole faces the screening screen.
[0010] Preferably, the screening box is provided with a flow guide near the feeding channel, and the flow guide is inclined along the side wall of the screening box toward the feeding channel.
[0011] Preferably, a deformation bending portion is provided at the edge of the cover, and a fixing hole is provided on the deformation bending portion. The deformation bending portion is fixedly connected to the sieve box by bolts through the fixing hole.
[0012] Preferably, an isolation pad is provided inside the limiting port.
[0013] Preferably, an electromagnetic lock is provided on the surface of the sieve box that abuts against the cover.
[0014] Compared with the prior art, the present invention provides a feeding auger screening device, which has the following beneficial effects:
[0015] 1. As the feeding screw rotates along the feed pipe, the feed in the hopper is transported to the batching device. During this process, when the feed in the feeding pipe reaches the feed hole, a screening screen is installed on the screening box located at the feed hole. The power of the rotating feeding screw causes the small particles of feed to be screened through the screening screen. The screened small particles of feed are separated from the screening box through the discharge channel, and the large particles of feed are transported to the batching device. This plays a positive guiding role in reducing the amount of small particles of feed that accumulate at the bottom of the feed trough.
[0016] 2. The material conveying pipe is fixed by the cooperation of the cover and the screening box, which is simple to operate. At the same time, when it is necessary to replace or maintain the screening screen, simply remove the cover, then remove the material conveying pipe along the screening box, and take out the screening screen along the screening box. The operation is simple.
[0017] 3. The guide section guides the small particles of feed separated by the screening mesh along the feeding channel, so that the small particles of feed separated by the screening mesh can be quickly fed into the screening box, reducing the amount of small particles of feed accumulating at the bottom of the screening box.

Detailed Implementation
[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0024] This application discloses a feeding auger screening device. (Refer to...) Figure 1 and Figure 2 A feeding auger sieving device includes a sieving box 1, a feeding channel 2 and a feeding pipe 3 on the sieving box 1, a feeding screw rotating through the feeding pipe 3, a feeding hole 4 on the feeding pipe 3, the feeding hole 4 being formed by penetrating the outer wall of the feeding pipe 3 along the thickness direction, a screening screen 5 on the sieving box 1 located at the feeding hole 4, the feeding channel 2 being located below the feeding hole 4, the sieving box 1 being hollow inside, the small particles of feed screened along the screening screen 5 falling into the sieving box 1 and being discharged through the feeding channel 2.
[0025] Specifically, the screening box 1 is formed by stamping and bending a metal sheet, which improves the rigidity of the screening box 1 and facilitates its assembly.
[0026] Furthermore, the two ends of the screening box 1 along the length direction are recessed in the thickness direction to form support grooves 11, which support the feed pipe 3 and limit the placement position of the feed pipe 3 along the screening box 1.
[0027] Correspondingly, a cover 6 is provided on the screening box 1, which covers the screening box 1. The cover 6 has a limiting opening 61, the outline of which matches the outline of the feed tube 3. The cover 6 is also formed by bending a metal sheet to reduce the overall weight of the cover 6. The limiting opening 61 is formed at the end of the cover 6 facing the screening box 1.
[0028] During the assembly process, the feed tube 3 is first placed in the support groove 11 of the sieve box 1, and then the cover 6 is placed on the sieve box 1. At this time, the outline formed by the support groove 11 and the limiting port 61 is the same as the cross-sectional shape of the feed tube 3, so that the feed tube 3 can be stably fixed between the sieve box 1 and the cover 6.
[0029] Meanwhile, a deformation bending part 9 is provided at the edge of the cover 6, and a fixing hole 91 is provided on the deformation bending part 9. The deformation bending part 9 is fixedly connected to the sieve box 1 through the fixing hole 91 using bolts.
[0030] The deformable bending part 9 is formed by protruding along the edge of the end of the cover 6 that abuts against the screening box 1, and the deformable bending part 9 is integrally formed with the cover 6. If there is a gap between the limiting port 61 and the feed tube 3, when the cover 6 is closed on the screening box 1 where the feed tube 3 is placed, the feed tube 3 cannot be fixed by the cover 6. Therefore, when there is a gap between the limiting port 61 and the feed tube 3, a force can be applied to the deformable bending part 9 to deform the deformable bending part 9, thereby reducing the gap between the limiting port 61 and the feed tube 3, so that the feed tube 3 abuts against the limiting port 61. At this time, when the cover 6 is closed on the screening box 1, the feed tube 3 is fastened between the cover 6 and the screening box 1 by the cooperation of the cover 6 and the screening box 1, so as to avoid the feed tube 3 shaking between the screening box 1 and the cover 6.
[0031] In addition, an isolation pad (not shown in the figure) is provided inside the limiting port 61. The material of the isolation pad can be rubber, which makes it soft and easy to deform. When the cover 6 is closed on the screening box 1, the isolation pad further fills the gap between the limiting port 61 and the feeding pipe, so as to improve the stability of the feeding pipe, the cover 6 and the screening box 1.
[0032] Reference Figure 1 and Figure 2 A limiting platform 7 is provided on the screening box 1, and the screening screen 5 is set on the limiting platform 7. When the material pipe 3 is set on the screening screen 5, the material pipe 3 abuts against the surface of the screening screen 5, and the material hole 4 faces the screening screen 5.
[0033] The screen 5 has a U-shaped outline and is formed by bending a metal sheet. Several screen holes 51 are opened through the surface of the screen 5 along the thickness direction. The diameter of the screen holes 51 can be changed according to the actual size of the feed. The diameter of the screen holes 51 is not limited here.
[0034] Furthermore, the limiting platform 7 is located on the two side walls of the screening box 1 along the length direction, and the limiting platform 7 is integrally formed with the screening box 1. The limiting platform 7 supports the screening screen 5 to improve the stability of the screening screen 5 when it is placed in the screening box 1.
[0035] The screening screen 5 has a bent portion 52 on its surface. The bending arc of the bent portion 52 is the same as the arc of the cross-sectional outline of the feed tube 3, so that the surface of the feed tube 3 can fit into the surface of the screening screen 5.
[0036] During the assembly process, the screening screen 5 is first placed on the screening box 1 and supported by the limiting platform 7. Then, the material conveying pipe 3 is placed in the support groove 11 on the screening box 1, and the cover 6 is closed on the screening box 1 to secure the material conveying pipe 3 and the screening screen 5 between the screening box 1 and the cover 6.
[0037] Reference Figure 1 A guide section 8 is provided near the feeding channel 2 in the screening box 1. The guide section 8 is inclined along the side wall of the screening box 1 to the feeding channel 2. The guide section 8 guides the small particle feed after it has been screened by the screening screen 5 along the movement path of the feeding channel 2, so that the small particle feed after it has been screened by the screening screen 5 can be quickly fed into the screening box 1, reducing the amount of small particle feed that accumulates at the bottom of the screening box 1.
[0038] In another embodiment, refer to Figure 3 and Figure 4 An electromagnetic lock 10 is provided on the surface of the sieve box 1 that abuts against the cover 6.
[0039] The sieve box 1 has a fastening part 101 at one end along its length. The fastening part 101 is formed by bending upward from the edge along the length of the sieve box 1. A fastening position 102 is formed between the fastening part 101 and the surface of the sieve box 1. The width of the fastening position 102 and the thickness tolerance of the deformed bending part 9 are in a clearance fit.
[0040] Correspondingly, the electromagnetic lock 10 is installed at the end of the sieve box 1 away from the end where the fastening part 101 is provided.
[0041] Therefore, when it is necessary to close the cover 6 onto the sieve box 1, firstly, the cover 6 is moved at an angle to the sieve box 1, and the deformed bending part 9 is inserted into the buckle 102. Then, the cover 6 is adjusted along the placement position of the sieve box 1 so that the cover 6 closes onto the sieve box 1. Then, the electromagnetic lock 10 is energized. Using the magnetic force generated by the electromagnetic lock 10, the cover 6 can be attracted to the sieve box 1. The operation is simple and does not require other mechanical structures to fix the cover 6.
[0042] The implementation principle of the feeding auger screening device in this application embodiment is as follows: First, the screening screen 5 is placed on the screening box 1, so that the bent part of the screening screen 5 is located in the limiting groove. Then, the conveying pipe 3 with the conveying hole 4 is placed in the limiting groove, so that the conveying hole 4 faces the screening screen 5. The feeding screw is inserted into the conveying pipe 3. Then, the cover 6 is covered on the screening box 1 and fixed. When the feeding screw rotates along the conveying pipe 3, it will drive the feed located in the conveying pipe 3 to be transported. When the small particle feed reaches the conveying hole 4, the small particle feed will reach the screening screen 5 along the conveying hole 4. The small particle feed is screened by the screening screen 5 and discharged along the discharge channel 2. The large particle feed will continue to be transported to the batching device through the conveying pipe 3, which reduces the amount of small particle feed put into the feed trough through the batching device and plays a positive guiding role in reducing the amount of small particle feed accumulated at the bottom of the feed trough.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
