Description

Technical Field

[0001] The utility model relates to the technical equipment for black soldier fly breeding, in particular to a multi-layer screening machine for black soldier fly manure. Background Art

[0002] In the prior art, the black soldier fly is a saprophagous insect of the family Stratiomyidae, which can feed on livestock and poultry manure and domestic waste, and produce high-value animal protein feed. Because of its rapid reproduction, large biomass, wide feeding habits, high absorption and conversion rate, easy management, low feeding cost, good animal palatability and other characteristics, it can be resourcefully utilized and is now mass-produced through artificial breeding.

[0003] In the prior art, the screening mechanisms for black soldier flies can be basically divided into two types. One is to utilize the characteristic that black soldier flies are afraid of high temperature, and through a heating and high-temperature device, make the black soldier flies drill to the low-temperature area for screening. For example, in the technical solution disclosed in Publication (Announcement) No.: CN116493245A, "A Black Soldier Fly Screening and Separating Device" is disclosed; and in the technical solution disclosed in Publication (Announcement) No.: CN114287391A, "A Black Soldier Fly Temperature Difference Screening Device" is disclosed.

[0004] However, because the above-mentioned method has a relatively complex structure setting and is not very convenient to operate, temperature control treatment is required. If the temperature control is not in place, it is very easy to cause the death of black soldier fly bodies, resulting in more losses than gains; moreover, the efficiency is not high, and various steps such as heating and cooling are required, which is not convenient to use.

[0005] Therefore, in the prior art, a mechanical screening structure is usually directly adopted to achieve screening. For example, in the "A Black Soldier Fly Screening Device and Its Screening Method" disclosed in Publication (Announcement) No.: CN115055369B, this technical solution directly adopts a shaking screen for screening.

[0006] For example, the technical solution of the "An Automatic Screening Device for Black Soldier Fly Larvae" disclosed in Publication (Announcement) No.: CN215278486U adopts the method of sliding an electric motor push rod for screening, and can all complete the screening relatively quickly and rapidly.

[0007] However, in the above-mentioned technical solutions, although the screening of black soldier flies is a relatively common form, when it comes to discharging the different screened materials, it will be very troublesome and cannot achieve a relatively smooth discharging method.

[0008] Therefore, in order to solve the above problems, it is necessary to develop a multi-layer screening machine for black soldier fly manure with reasonable structure and convenient use. Summary of the Invention

[0009] The purpose of the present utility model is to provide a multi-layer screening machine for black soldier fly manure aiming at the deficiencies existing in the prior art; the technical solution is as follows:

[0010] A multi-layer screening machine for black soldier fly manure includes a screening box and a screening motor arranged above the screening box, and the main shaft of the screening motor is correspondingly installed on the box cover at the upper end of the screening box; and a plurality of annular screening nets are also arranged in the screening box, and the screening nets are arranged concentrically. The space inside the screening box is divided into several screening areas by the screening nets, and the aperture of the mesh holes of the screening nets decreases successively from the inside to the outside. When the screening box rotates driven by the screening motor, the screening nets correspondingly drive the black soldier fly mixed materials in the screening box for screening;

[0011] A ring-shaped support frame is also arranged at the lower end of the screening box, and the support frame is arranged at the outer edge position of the lower end of the screening box. A material receiving area is formed inside the support frame, and material receiving boxes corresponding to the positions of each screening area in the screening box are placed in the material receiving area. The material receiving box is of an annular box structure with an open upper end;

[0012] And a discharging mechanism is also arranged at the position of the bottom plate of the screening box, and the materials in each screening area are received into the corresponding material receiving box through the discharging structure.

[0013] Furthermore, a feed inlet is arranged at the upper end of the box cover of the screening box, and the feed inlet is arranged on the upper box cover of the innermost screening area. A feed pipe is correspondingly arranged above the feed inlet.

[0014] Furthermore, a transverse support is also arranged at the upper end of the support frame; the transverse support extends horizontally towards the inside and does not interfere with the rotation of the screening box.

[0015] Furthermore, a ball groove is also arranged on the transverse support, and balls are correspondingly placed in the ball groove to support the screening box through the balls.

[0016] Furthermore, the discharging mechanism includes a discharging motor, and the discharging motor is arranged on the bottom plate of the innermost screening area. After the main shaft of the discharging motor extends downward, a long strip-shaped discharging bottom plate is installed;

[0017] And discharging ports are correspondingly arranged on the bottom plate of each screening area in the screening box; and all the discharging ports are correspondingly arranged on the same straight line, and the discharging bottom plate correspondingly blocks all the discharging ports. When the position of the discharging bottom plate changes, the discharging ports are correspondingly opened.

[0018] Furthermore, two discharging ports are correspondingly arranged on the bottom plate of each screening area in the screening box.

[0019] Furthermore, a protective housing is also provided outside the discharging motor.

[0020] Advantages: The present utility model has the following advantages:

[0021] 1) In this device, the screening box can rotate correspondingly driven by the screening motor.

The overall structure is very reasonable, and the use and operation are very convenient and smooth. Moreover, the screening efficiency is high and the quality is good, which can be widely promoted;

[0022] 2) Since the screening box is suspended in this device, it is not stable. This device correspondingly sets a circumferential support frame, and also sets a transverse support and installs balls inside the transverse support. The whole screening box is supported by the balls, and the rotation of the screening box is realized in cooperation with the screening motor above. The structure is reasonable, stable and reliable;

[0023] 3) In this device, discharging ports are provided on the bottom plate of the box in each screening area, and two are provided in each screening area. A discharging motor is installed in the middlemost screening area. The main shaft of the discharging motor is connected to install a long strip-shaped discharging plate, and the discharging plate is closely attached to the lower end face position of the screening box. Since all the discharging ports are on the same straight line, the discharging plate can block all the discharging ports. Then when the screening box rotates, the material will not leak, and the screening of the material can be normally realized. The structure setting is ingenious and reasonable, and it is convenient to use;

[0024] 4) When discharging in this device, by adjusting the position of the discharging plate through the discharging motor, the discharging plate can be rotated by 90°. At this time, all the discharging ports are opened to realize discharging; and an annular receiving box is provided below the discharging port in each screening area. When the discharging port is opened, the material correspondingly falls into the placed receiving box to realize classification. The structure setting is very reasonable. Description of the Drawings
