Description

Technical Field

[0001] The utility model relates to the technical field of larvae cultivation, in particular to a small-sized insect larvae cultivation device. Background Art

[0002] Insects are of various types and shapes. They belong to arthropods among invertebrates and are the most numerous animal group on earth. In the process of development, insects need to go through four stages: eggs, larvae, pupae and adults. Larval cultivation refers to the whole process of cultivation from the initial ear-shaped larvae to the barrel-shaped larvae. During the larval cultivation process, the larvae are fed, and after eating, the insect feces produced need to be screened out, and the insect feces need to be screened out every few days. Larval cultivation in the prior art is usually carried out using a cultivation box, but when the existing cultivation box screens out the insect feces, the larvae need to be taken out of the cultivation box, and then the insect feces need to be screened out using a sieve. The sieve also needs to be shaken when screening, and the insect feces need to be screened out every few days, which is very troublesome and wastes manpower; during the growth of the larvae, when the sieve is used to screen out the insect feces, the mesh size of the sieve used in different growth periods is also different. Generally, multiple sieves with different mesh sizes need to be prepared in advance, which is very troublesome. Utility Model Content

[0003] The utility model aims to provide a small insect larvae breeding device, which can change the mesh size of the screen according to needs, facilitate the screening of insect feces produced by larvae in different growth periods, and can also adjust the interval time of insect feces screening according to needs to automatically screen out the insect feces.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A small-sized insect larvae breeding device comprises a breeding box, wherein the upper side of the front end of the breeding box is provided with a box opening, the front side of the breeding box is rotatably connected to box doors at both left and right ends of the box opening, a screen is rotatably connected to the inside of the breeding box, a support rod rotatably connected to the left side of the inside of the breeding box is provided at the lower end of the outer side of the screen, a support cylinder rotatably connected to the right side of the inside of the breeding box is provided at the lower end of the outer side of the screen, a grid plate is rotatably connected to the lower end of the screen, the mesh holes on the screen and the grid plate are equal in size and are connected to each other, an annular rack is provided on the outer side of the grid plate, the support cylinder is rotatably connected to the inside of the support cylinder with one end passing through the breeding box and rotatably connected to the first rotating shaft, one end of the first rotating shaft is provided with a first gear meshing with the annular rack, and the other end of the first rotating shaft passes through the breeding box and is provided with a knob;

[0006] A second gear is provided on the outer side of the support rod, a third gear is provided on the outer side of the support cylinder, a support shell is provided at the center of the bottom of the incubator, a second rotating shaft is transmission-connected to a side of the support shell close to the second gear, a third rotating shaft is rotationally connected to a side of the support shell close to the third gear, a first intermittent gear meshing with the second rotating shaft is provided at one end of the second rotating shaft close to the second gear, a second intermittent gear meshing with the third rotating shaft is provided at one end of the third rotating shaft close to the third gear, the teeth on the first intermittent gear and the teeth on the second intermittent gear are arranged opposite to each other, a first bevel gear is provided at one end of the second rotating shaft away from the first intermittent gear, a second bevel gear is provided at one end of the third rotating shaft away from the second intermittent gear, a driving device for driving the first bevel gear and the second bevel gear to rotate is provided in the support shell, and a time controller is installed on one side of the incubator.

[0007] By adopting the above technical solution, the box door is opened, and the larvae can be conveniently placed into the screen from the box opening for cultivation. During the cultivation process, the larvae will produce insect feces, and the hammer powder can be directly screened out through the screen. The larvae at different stages grow to different sizes, and the sizes produced are also different. It is necessary to adjust the size of the mesh on the screen. By turning the knob, the first shaft drives the first gear to rotate, and the first gear drives the annular rack to rotate. The grid plate rotates relative to the screen with the annular rack, and the mesh holes on the grid plate and the mesh holes on the screen are staggered. The size of the through hole formed between the two is changed, which makes it convenient to screen out insect feces of different sizes without letting the larvae fall. The drive device is started to drive the second rotating shaft and the third rotating shaft to rotate, the second rotating shaft drives the first intermittent gear to rotate, and the third rotating shaft drives the second intermittent gear to rotate. When the first intermittent gear drives the second gear to rotate, the second intermittent gear does not drive the third gear to rotate. The rotation of the second gear drives the support rod to rotate together, and the screen rotates forward and the supporting cylinder rotates with it. When the first intermittent gear does not drive the second gear to rotate, the second intermittent gear drives the third gear to rotate, and the supporting cylinder can rotate with it, and can drive the screen to rotate backward. By driving the screen to rotate forward or backward, the screen is shaken to screen out the insect feces in the screen.

[0008] The utility model is further configured as follows: the driving device includes a third bevel gear rotatably connected to the rear end of the support shell and meshing with the first bevel gear and the second bevel gear, and a motor is installed on the rear side of the support shell to drive the third bevel gear to rotate.

[0009] The utility model is further configured as follows: a first spring is arranged on the outer side of the support rod, one end of the first spring is connected to the support rod, the other end of the first spring is connected to the incubator, and a second spring is arranged on the outer side of the support cylinder, one end of the second spring is connected to the support cylinder, and the other end of the second spring is connected to the incubator.

[0010] The utility model is further configured as follows: a slide groove is provided from front to back at the front end of the culture container near the box opening, and the slide groove is connected to a collection box.

[0011] The utility model is further configured as follows: a power plug is provided on one side of the incubator.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] First, the mesh size of the screen can be adjusted according to the size of the excrement produced by the larvae at different stages, so as to facilitate the removal of the excrement. By turning the knob, the first gear is driven to rotate through the first rotating shaft, and then the grid plate is driven to rotate relative to the screen. The grid plate blocks the lower end of the mesh on the screen, thereby changing the size of the through hole formed by the mesh on the screen and the mesh on the grid plate;

[0014] Secondly, the interval time of insect excrement screening can be adjusted according to needs, and then the insect excrement can be automatically screened out. The interval time is set through the time controller, and then the motor rotates the third bevel gear, and the third bevel gear drives the first bevel gear and the second bevel gear in different directions respectively. Through the first intermittent gear and the second intermittent gear, the screen can be driven forward or backward to quickly screen out insect excrement. During the rotation of the screen, the first spring or the second spring can be compressed, and then during the resetting of the screen, the first spring or the second spring can make the screen vibrate, so that the insect excrement can be screened out faster.
