Description

Technical Field

[0001] This utility model relates to the field of ground beetle breeding, and in particular to a rapid separation and screening machine for ground beetles and feed residue. Background Technology

[0002] As an insect with high medicinal value, the breeding scale of ground beetles is gradually expanding. In the process of raising ground beetles, the selection and use of feed is crucial. Wheat bran, cornmeal and other foods have become commonly used feeds because their nutritional composition is more in line with the growth needs of ground beetles. They are an important material basis for ground beetles to obtain energy.

[0003] In the breeding process of ground beetles, the ground beetles will be mixed with feed residue. It is necessary to screen the ground beetles and feed residue to facilitate the collection and utilization of feed residue. However, at present, the separation of ground beetles and feed residue is usually done by breeders using simple screens to screen the mixture of ground beetles and feed residue. However, this method is inefficient, requires frequent feeding of the mixture of ground beetles and feed residue, and is not convenient for cleaning the ground beetles on the screen, which reduces the screening speed of the mixture of ground beetles and feed residue. To solve the above problems, we propose a rapid separation and screening machine for ground beetles and feed residue. Utility Model Content

[0004] The purpose of this invention is to provide a rapid separation and screening machine for ground beetles and feed residue, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid separation and screening machine for ground beetles and feed residue includes a screening cylinder, a feeding hopper above the screening cylinder, a variable frequency motor fixedly mounted on the upper surface of the screening cylinder, a drive rod fixedly mounted on the output end of the variable frequency motor, a spiral blade fixedly connected to the outer surface of the drive rod, the spiral blade located inside the feeding hopper, a distribution rod fixedly mounted at the bottom end of the drive rod, multiple upper discharge blades fixedly connected to the outer surface of the distribution rod, an annular guide screen fixedly connected to the inner wall of the screening cylinder, each of the upper discharge blades being located above the annular guide screen, and multiple lower discharge blades fixedly connected to the outer surface of the distribution rod.

[0007] In a further embodiment, the outer surface of the screening cylinder is fixedly connected to an upper discharge pipe, the inner wall of the screening cylinder is provided with a ground beetle discharge hole, one end of the ground beetle discharge hole is connected to one end of the upper discharge pipe, the bottom surface of the screening cylinder is provided with a feed residue discharge hole, and the bottom end of the feed residue discharge hole is fixedly connected to a lower discharge pipe.

[0008] In a further embodiment, a support base is fixedly connected to the upper surface of the screening cylinder, and the upper surfaces of the two support bases are fixedly connected to the outer surface of the feeding hopper. A plurality of support stands are fixedly connected to the bottom surface of the screening cylinder, and a shock-absorbing base is fixedly connected to the bottom end of each support stand.

[0009] In a further embodiment, a bearing is fixedly embedded in the inner top wall of the injection hopper, and the inner ring of the bearing is fixedly connected to the outer surface of the drive rod.

[0010] In a further embodiment, the bottom end of the feeding hopper is fixedly connected to a connecting cover, the bottom end of the connecting cover is fixedly connected to the top end of the screening cylinder, and the upper surface of the feeding hopper is fixedly connected to the feeding cover.

[0011] In a further embodiment, a controller is fixedly installed on the upper surface of the screening cylinder, and the controller is electrically connected to the variable frequency motor via a wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the setting of the feeding hopper, and in conjunction with a variable frequency motor, drive rod, and spiral blades, enables continuous downward feeding of the mixture of ground beetles and feed residue inside the feeding hopper, thus automating the feeding process and improving screening efficiency. Simultaneously, the drive rod rotates the distribution rod and the upper and lower discharge blades, allowing the mixture of ground beetles and feed residue to be initially dispersed within the screening cylinder. Furthermore, the annular guide screen and rotating material feeding mechanism separate the ground beetles and feed residue based on their size differences. In addition, the upper and lower discharge blades on the surface of the distribution rod push the ground beetles and feed residue through corresponding discharge holes, eliminating the need for manual cleaning of the ground beetles above the annular guide screen, thus increasing screening speed and facilitating the collection and utilization of feed residue.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model discloses a rapid separation and screening machine for ground beetles and feed residue, comprising a screening cylinder 1, a feeding hopper 2 above the screening cylinder 1, a variable frequency motor 3 fixedly mounted on the upper surface of the screening cylinder 1, a drive rod 4 fixedly mounted on the output end of the variable frequency motor 3, a spiral blade 5 fixedly connected to the outer surface of the drive rod 4, the spiral blade 5 being located inside the feeding hopper 2, a distribution rod 7 fixedly mounted on the bottom end of the drive rod 4, multiple upper discharge blades 8 fixedly connected to the outer surface of the distribution rod 7, and an annular guide screen 9 fixedly connected to the inner wall of the screening cylinder 1. Each upper discharge blade 8 is located above the annular guide screen 9. Multiple lower discharge blades 10 are fixedly connected to the outer surface of the distribution rod 7. The feeding hopper 2 is used to receive the mixture of ground beetles and feed residue. The spiral blades 5 are rotated by the variable frequency motor 3 and the drive rod 4 to realize automated feeding. By using the rotation of the upper discharge blades 8, the mixture can be initially dispersed above the annular guide screen 9. The annular guide screen 9 then separates the ground beetles and feed residue according to the size difference, combined with gravity and rotational force, thus completing the screening.

[0024] In a further embodiment, an upper discharge pipe 12 is fixedly connected to the outer surface of the screening cylinder 1. A ground beetle discharge hole 11 is opened on the inner wall of the screening cylinder 1, with one end of the hole connected to one end of the upper discharge pipe 12. A feed residue discharge hole 19 is opened on the bottom surface of the screening cylinder 1, with a lower discharge pipe 20 fixedly connected to the bottom end of the discharge hole 19. A support base 15 is fixedly connected to the upper surface of the screening cylinder 1, and the upper surfaces of both support bases 15 are fixedly connected to the outer surface of the feeding hopper 2. Multiple support stands are fixedly connected to the bottom surface of the screening cylinder 1. 17. Each support stand 17 is fixedly connected to a shock-absorbing base 18 at its bottom end. It is connected to the earthworm discharge hole 11 through the upper discharge pipe 12 to discharge the earthworms above the screen. The feed residue discharge hole 19 is connected to the lower discharge pipe 20 to discharge the feed residue, thereby completing the separate collection of earthworms and feed residue. The support stand 15 can stabilize the feeding hopper 2 above the screening cylinder 1. Through the cooperation of the support stand 17 and the shock-absorbing base 18, the stability of the equipment during operation is ensured and the impact of vibration on the screening process and the equipment itself is reduced.

[0025] In a further embodiment, a bearing 6 is fixedly embedded in the inner top wall of the feeding hopper 2. The inner ring of the bearing 6 is fixedly connected to the outer surface of the drive rod 4. A connecting cover 13 is fixedly connected to the bottom end of the feeding hopper 2. The bottom end of the connecting cover 13 is fixedly connected to the top end of the screening cylinder 1. A feeding cover 14 is fixedly connected to the upper surface of the feeding hopper 2. A controller 16 is fixedly installed on the upper surface of the screening cylinder 1. The controller 16 is electrically connected to the variable frequency motor 3 through wires. The bearing 6 can reduce the friction when the drive rod 4 rotates, ensuring smooth power transmission. The connecting cover 13 can connect the feeding hopper 2 and the screening cylinder 1, ensuring stable material conveying. The feeding cover 14 facilitates the injection of mixtures. Through the electrical connection between the controller 16 and the variable frequency motor 3, the operator can flexibly adjust the motor speed according to actual needs and accurately control the screening process.

[0026] The working principle of this utility model is as follows: First, the mixture of ground beetles and feed residue is injected into the feeding hopper 2 through the feeding hood 14. At this time, the variable frequency motor 3 starts and drives the spiral blade 5 in the feeding hopper 2 to rotate through the drive rod 4, which can convey the mixture downward to the screening cylinder 1. In addition, the drive rod 4 can drive the bottom distribution rod 7 to rotate. The upper discharge blade 8 and the lower discharge blade 10 on the distribution rod 7 rotate accordingly. The upper discharge blade 8 initially disperses the mixture, which can make the material more evenly distributed above the annular guide screen 9. Then, after the mixture is dispersed above the annular guide screen 9, the ground beetles and feed residue are separated under the action of gravity and centrifugal force due to the difference in size. The feed residue falls through the mesh of the annular guide screen 9, while the ground beetles remain above the annular guide screen 9.

[0027] Then, the ground beetles remaining above the annular guide screen 9 are pushed by the upper discharge blade 8 during the continuous rotation of the distribution rod 7, and enter the upper discharge pipe 12 through the ground beetle discharge hole 11 to complete the discharge. Meanwhile, the feed residue that passes through the annular guide screen 9 is discharged through the feed residue discharge hole 19 into the lower discharge pipe 20 under the rotation of the lower discharge blade 10 on the surface of the distribution rod 7, thus realizing the separate collection of ground beetles and feed residue, which facilitates the subsequent utilization of feed residue.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
