Description

Technical Field

[0001] The utility model belongs to the technical field of white-spotted flower beetle breeding equipment, in particular to a larva screening device for white-spotted flower beetle breeding. Background Art

[0002] There are two types of white-spotted flower beetles: herbivorous and saprophagous. The herbivorous white-spotted flower beetles are pests, but the saprophagous white-spotted flower beetles like to eat rotten straw, mushroom chaff, weeds and other humus foods, and generally do not harm the roots of living plants. Moreover, the larvae of the white-spotted flower beetles are a kind of traditional Chinese medicinal material with great medicinal value. The feces of the larvae are uniform in size, rich in organic matter, and have strong adsorption properties, so they can be used as organic fertilizer. Therefore, the saprophagous white-spotted flower beetles have good breeding prospects.

[0003] The entire life cycle of the white-starred flower beetle is divided into eggs, larvae, pupae and adults. Since the larvae of the white-starred flower beetle can be used as Chinese medicinal materials after processing, and the larvae of the white-starred flower beetle can also be made into feed, the white-starred flower beetle can be utilized for economic value when it becomes a larvae; and since the existing white-starred flower beetle larvae are all cultured in breeding boxes and mixed with breeding base materials, it is necessary to screen the white-starred flower beetle larvae from the breeding base materials.

[0004] The existing screening of white-spotted flower beetle larvae is mostly done by manually pulling or shaking the screen back and forth to make the culture substrate fall from the screen, so that the white-spotted flower beetle larvae remain on the screen, and then the white-spotted flower beetle larvae are collected; however, this method requires the operator to lift the screen for operation, and since the screen and the culture substrate are heavy, the operator's physical strength is greatly consumed. After a long period of operation, the large physical consumption has a greater impact on work efficiency, and the operator is also relatively tired. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0023] The larva screening device for breeding white-spotted scarab beetles described in this embodiment is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a horizontally arranged first movable plate 8, a first through hole communicating with each other from top to bottom is opened on the first movable plate 8, a screen 12 is installed in the first through hole, the first through hole is preferably a rectangular hole, the screen 12 is a grid-shaped rectangular plate, a mounting plate is fixed on the edge of the screen 12, a through hole is opened on the mounting plate, the mounting plate is fixed to the top of the first movable plate 8 by bolts, so that the screen 12 is fixed in the first through hole on the first movable plate 8, and can be disassembled; of course, in some embodiments, the first movable plate 8 and the screen 12 are made of metal, and the screen 12 is welded to the first movable plate 8.

[0024] Below the first movable plate 8, there is a collection trough 1 for collecting the breeding substrate that falls from the sieve 12. The collection trough 1 is a box structure in the shape of a rectangle without a lid. The width and length of the first through hole are smaller than the width and length of the inner side wall of the collection trough 1, so that the sieve 12 is located above the collection trough 1. At least two symmetrically distributed first fixing plates 3 are horizontally fixed on the outer side wall of the collection trough 1. Between the first fixing plate 3 and the first movable plate 8, there is a vertically arranged spring 4. In the natural state of the spring 4, there is a gap between the first movable plate 8 and the collection trough 1.

[0025] There are two first fixing plates 3. The two first fixing plates 3 are respectively fixed to the left and right outer side walls of the collection trough 1. One first fixing plate 3 is fixed to the left outer side wall of the collection trough 1, and one first fixing plate 3 is fixed to the right outer side wall of the collection trough 1. A movable rod 5 is vertically inserted through each spring 4. To better support the first movable plate 8, as Figure 5 shown, there are two springs 4 between the first fixing plate 3 on each side and the first movable plate 8. Second through holes for the bottom ends of the movable rods 5 to pass through are formed on the first fixing plates 3. The top ends of the movable rods 5 all extend beyond the springs 4 and are horizontally fixed with a second movable plate 7. The spring 4 is located between the second movable plate 7 and the first fixing plate 3. The top end of the spring 4 is fixed to the bottom of the second movable plate 7, and the bottom end of the spring 4 is fixed to the top of the first fixing plate 3. One of the second movable plates 7 is hinged to the bottom of the first movable plate 8 to make the first movable plate 8 swing left and right. The left second movable plate 7 is hinged to the left end of the first movable plate 8;

[0026] The right second movable plate 7 and the right end of the first movable plate 8 are connected by a card slot 6. The card slot 6 is in a "C" - shaped structure. The card slot 6 includes a horizontally arranged top plate and a horizontally arranged bottom plate. The top plate and the bottom plate are connected by a vertically arranged connecting plate. The distance between the top plate and the bottom plate is the same as the thickness of the second movable plate 7 and the first movable plate 8. Through the card slot 6, the second movable plate 7 and the first movable plate 8 can be made to be in close contact, so as to fix the second movable plate 7 and the first movable plate 8. This paragraph of text as a whole constitutes a locking assembly for locking the right - hand second movable plate 7 and the right end of the first movable plate 8. Of course, in some embodiments, the locking assembly can also include a screw. Installation holes for the screw to pass through are formed at the right ends of the right second movable plate 7 and the first movable plate 8. There are two nuts threadedly engaged with the screw on the screw. When fixing, after the right end of the first movable plate 8 is located on the top of the right second movable plate 7, the screw is inserted into the installation hole, and then the two nuts are screwed in from the top end and the bottom end of the screw respectively, so as to make the second movable plate 7 and the first movable plate 8 in close contact. When in use, after the sieve 12 has completed the screening of the Protaetia brevitarsis, the right end of the first movable plate 8 can be lifted upward to make the first movable plate 8 inclined, and then the Protaetia brevitarsis on the sieve 12 can be made to roll to the left, which is convenient for collecting the Protaetia brevitarsis screened out on the sieve 12.

[0027] Of course, when the right end of the first movable plate 8 does not need to be lifted, the first fixed plate 3 can be horizontally fixed on the front side wall and the left and right side walls of the collecting tank 1, and the spring 4 is vertically fixed between the first fixed plate 3 and the first movable plate 8. By compressing the spring 4, the first movable plate 8 moves up and down to complete the screening of the white star flower beetle and the breeding base material.

[0028] The bottom end of the movable rod 5 exceeds the second through hole fixed limit block 2, and the limit block 2 is used to prevent the movable rod 5 from escaping from the second through hole. The second through hole is a circular hole, and the limit block 2 is a circular plate. The diameter of the second through hole is smaller than the diameter of the limit block 2. The limit block 2 can limit the maximum distance that the movable rod 5 moves upward. After the first movable plate 8 is pressed downward to compress the spring 4, the first movable plate 8 is released. When the spring 4 recovers its elasticity, the bottom end of the movable rod 5 can be prevented from escaping from the second through hole on the first fixed plate 3. Of course, when the spring 4 is in a natural state, there is a gap between the limit block 2 and the first fixed plate 3, which can reduce the restriction of the limit block 2 on the extension and contraction of the spring 4; of course, in some embodiments, the length of the movable rod 5 can also be made longer, so that the bottom end of the movable rod 5 exceeds the bottom of the first fixed plate 3 by a longer distance, so that when the first movable plate 8 moves up and down, the bottom end of the movable rod 5 is always located below the first fixed plate 3.

[0029] A first slider 18 is fixed to the inner top of the slot 6, and a first slider 18 is fixed to the bottom of the top plate of the slot 6. Figure 5 As shown, the length of the first fixed plate 3 is smaller than the width of the first movable plate 8, a first slide groove is provided on the top of the first movable plate 8 for inserting the first slider 18 and sliding forward and backward, a second slider 17 is horizontally fixed to the bottom of the first slider 18, the second slider 17 is fixed to one side of the first slider 18 close to the connecting plate, that is, the first slider 18 is fixed to the bottom of the right side of the second slider 17, the first slider 18 and the second slider 17 are in an "L"-shaped structure as a whole, a second slide groove is provided at the bottom of the first slide groove for inserting the second movable plate 7 and sliding forward and backward, the first slide groove and the second slide groove are in an "L"-shaped slide groove as a whole, the second slider 17 can prevent the first slider 18 from detaching from the first slide groove, thereby preventing the card slot 6 from falling off the first movable plate 8, as shown in FIG. Figure 4As shown, when the card slot 6 is located at the front side of the first slide slot, the bottom of the card slot 6 is located at the bottom of the second movable plate 7 on the right side, and the second movable plate 7 and the right end of the first movable plate 8 are fixed. By pushing the card slot 6 backward, the card slot 6 is located at the rear side of the first slide slot, the card slot 6 is separated from the second movable plate 7, and the second movable plate 7 and the first movable plate 8 are separated. The right end of the first movable plate 8 can be lifted upward, and the second slider 17 and the first slider 18 can prevent the card slot 6 from being separated from the first movable plate 8, thereby avoiding the card slot 6 from being lost. The second slider 17 and the first slider 18 slide back and forth in the slide slot, so that the card slot 6 fixes and releases the second movable plate 7 and the first movable plate 8, and its operation is also relatively simple.

[0030] A second fixing plate 9 is vertically fixed to the top of the first movable plate 8 away from the hinged end, and the second fixing plate 9 is vertically fixed to the top of the right end of the first movable plate 8, and the left side wall of the second fixing plate 9 is flush with the right side of the first through hole. A third fixing plate 13 is vertically fixed to the top of the front and rear sides of the first movable plate 8. Two third fixing plates 13 are provided, and the rear side wall of the front third fixing plate 13 is flush with the front side of the first through hole, and the front side wall of the rear third fixing plate 13 is flush with the rear side of the first through hole. A third through hole communicating left and right is provided on the second fixing plate 9, and a cover plate 11 is independently provided in the third through hole. The inner side walls of the two third fixing plates 13 are both opened. A third slide groove is provided for inserting the front and rear sides of the cover plate 11 and sliding left and right, a third slide groove is provided on the front side wall of the rear third fixing plate 13, and a third slide groove is provided on the rear side wall of the front third fixing plate 13. The width of the cover plate 11 is smaller than the distance between the rear side wall of the rear third fixing plate 13 and the front side wall of the front third fixing plate 13, but the width of the cover plate 11 is larger than the distance between the front side wall of the rear third fixing plate 13 and the rear side wall of the front third fixing plate 13, so that the front and rear ends of the cover plate 11 are located in the third slide groove on the third fixing plate 13 for support, and a baffle 16 is vertically provided on the top of the side of the first movable plate 8 away from the second fixing plate 9, and the baffle 16 At the top of the left end of the first movable plate 8, the inner side walls of the two third fixed plates 13 away from the second fixed plate 9 are provided with a fourth slide groove for the baffle plate 16 to be inserted and slide up and down. The lengths of the front and rear sides of the baffle plate 16 are consistent with the width of the cover plate 11. The front and rear sides of the baffle plate 16 are located in the fourth slide groove, thereby limiting the left and right movement of the baffle plate 16. When the baffle plate 16 is located in the fourth slide groove, the right side wall of the baffle plate 16 is flush with the left side of the first through hole. The baffle plate 16, the second fixed plate 9 and the two third fixed plates 13 form a frame that is connected up and down as a whole, which can block the white star flower beetle and the breeding substrate on the top of the screen 12 to prevent During the screening process, the white-spotted flower beetles and the breeding base material fall from the edge of the first movable plate 8, and the cover plate 11 can block the screening of the screen 12. In this way, when the spring 4 recovers its elasticity, the first movable plate 8 moves upward instantaneously, and the white-spotted flower beetles and the breeding base material on the top of the screen 12 will not be thrown out. After the screening is completed, the baffle 16 is pulled upward, and then the right end of the first movable plate 8 is lifted, so that the white-spotted flower beetles screened out from the top of the screen 12 can fall from the left end of the first movable plate 8. Of course, the left end of the third fixed plate 13 is flush with the left end of the first movable plate 8, so that the white-spotted flower beetles can fall from the left end of the first movable plate 8.

[0031] When the left end of the cover plate 11 is located on the left side of the third slide groove, the baffle 16 is located below the left end of the cover plate 11, so that the cover plate 11 can block the baffle 16, and the spring 4 restores its elasticity, so that when the first movable plate 8 moves upward instantaneously, the cover plate 11 blocks the baffle 16, so that the baffle 16 can be prevented from sliding out of the fourth slide groove; of course, in order to prevent the cover plate 11 from sliding left and right during the screening process, a threaded hole is provided on the second fixing plate 9 at the top of the fourth through hole, and a bolt 10 is provided in the threaded hole to match the bolt 10, and the cover plate 11 can be fixed by the bolt 10; and in order to prevent the cover plate 11 from detaching from the third through hole on the second fixing plate 9, a limiting plate 15 is fixed on the top of the left end of the cover plate 11, and the length of the limiting plate 15 is less than the distance between the third fixing plates 13 on both sides of the front side.

[0032] A frame 14 is fixed to the bottom of the first movable plate 8 corresponding to the first through hole, and the inner wall of the frame 14 is flush with the first through hole. The first through hole is a rectangular structure, and the frame 14 is a rectangular structure. When the spring 4 is in a natural state, the horizontal height of the bottom end of the spring 4 is lower than the horizontal height of the top end of the collecting tank 1, that is, the bottom end of the spring 4 is located in the collecting tank 1, so that when the first movable plate 8 moves up and down, it can prevent the aquaculture substrate from falling from the screen 12 and then falling from the gap between the first movable plate 8 and the top of the side wall of the collecting tank 1, and can reduce the aquaculture substrate falling from the screen 12 and scattering outside the collecting tank 1.

[0033] Working principle:

[0034] When in use, the cover plate 11 is pulled to the right, and then the white star flower beetle larvae and the breeding base material are poured onto the top of the screen 12, and then the cover plate 11 is pulled to the left again, so that the cover plate 11 blocks the top of the screen 12, and then the first movable plate 8 is pressed downward to compress the spring 4, and then released to restore the elasticity of the spring 4. Through the elastic recovery of the spring 4, the first movable plate 8 is instantly raised upward, so that the white star flower beetles and the breeding base material above the screen 12 are shaken, and the breeding base material falls from the screen 12 into the collecting tank 1, and the spring 4 can move repeatedly after compression, so that the screening of the white star flower beetles and the breeding base material is better, and the first movable plate 8 can be pressed downward multiple times to make the screening of the white star flower beetles and the breeding base material more thorough. After the screening is completed, The card slot 6 slides backward to separate the left end of the first movable plate 8 and the second movable plate 7 on the left side, and then the cover plate 11 is pulled to the right, and then the baffle plate 16 is pulled upward, and then the right end of the first movable plate 8 is lifted, so that the white star flower beetle on the top of the screen 12 rolls to the left. A collecting container can be set below the left end of the first movable plate 8 to collect the white star flower beetle dropped from the left end of the first movable plate 8, which is more convenient; and the spring 4 is compressed to move the first movable plate 8 up and down, so that the screen 12 screens the white star flower beetle and the breeding base material. It only needs to press the first movable plate 8 downward, and the operation is relatively simple and labor-saving, which can reduce the physical exertion of the operator, keep the work efficiency for a longer time, and facilitate the screening of the white star flower beetle from the breeding base material.
