Description

Technical Field

[0001] This invention relates to the field of fly larvae farming technology, and more particularly to a quantitative feeder for fly larvae farming. Background Technology

[0002] Fly larvae are saprophytic insects that feed on livestock manure and kitchen waste. They are characterized by rapid reproduction, high absorption and conversion rates, low feeding costs, and good palatability to animals. Currently, people generally use breeding frames to raise fly larvae. By feeding the fly larvae regularly, they can reproduce and grow, thereby producing high-value animal protein feed and making resource utilization.

[0003] When feeding fly larvae, too little food will affect their reproduction rate, while too much food will cause the food to clump, harden, and spoil, leading to larval death and wasting food, thus increasing costs. Therefore, it is necessary to precisely control the amount of food based on the amount the fly larvae consume each time to ensure the freshness and utilization rate of the food. However, people usually feed them manually. If the food is directly put into the breeding basket, it is difficult to accurately control the weight of the food. If the food is weighed, the weight of the food needs to be weighed multiple times, which is cumbersome and affects work efficiency. Summary of the Invention

[0004] To overcome the shortcomings of current methods for manually feeding fly maggots, such as the difficulty in accurately controlling the amount of food fed directly and the need for multiple weighings of the food, which affects work efficiency, the purpose of this invention is to provide a quantitative feeder for fly maggot farming that can automatically and quantitatively feed the maggots.

[0005] The technical solution of the present invention is as follows: a quantitative feeder for fly larvae farming, comprising a mounting frame, an electric slide rail, a feeding box, a first connecting frame, guide rods, a first compression spring, a pressing plate, a feeding pump, a quantitative pressing mechanism, a squeezing and pushing mechanism, and a blocking mechanism. Several breeding frames for fly larvae are spaced apart on the mounting frame. An electric slide rail is mounted on the mounting frame, and a feeding box for holding feed is connected to the electric slide rail. Several first circular holes are arrayed and spaced apart on the feeding box. Two first connecting frames are connected to the feeding box. Two guide rods are slidably connected to each first connecting frame. A first compression spring is connected between each guide rod and an adjacent first connecting frame. A pressing plate for pressing out feed is connected between the four guide rods. The pressing plate is slidably connected to the feeding box. Two feeding pumps for conveying feed are mounted on the pressing plate. The quantitative pressing mechanism is used to quantitatively press the feed. A squeezing and pushing mechanism is provided on the first connecting frame on the left side, and a blocking mechanism is provided on the feeding box.

[0006] Optionally, the quantitative pressing mechanism includes a connecting box, a piston column, an electric exhaust valve, a connecting cylinder, a one-way vent pipe, a one-way valve, a piston rod, and a second compression spring. Two connecting boxes are connected between the two first connecting frames. A piston column is slidably connected inside each connecting box. The piston column is in sealed contact with the adjacent connecting box and is connected to the pressing plate. An electric exhaust valve is installed on each connecting box. A connecting cylinder is connected to each connecting box. Two one-way vent pipes are connected between each connecting cylinder and the adjacent connecting box. A one-way valve is installed on each connecting cylinder. A piston rod is slidably connected to each connecting cylinder. The piston rod is in sealed contact with the adjacent connecting cylinder and extends from the left side of the adjacent connecting cylinder. A second compression spring is connected between the piston rod and the adjacent connecting cylinder.

[0007] Optionally, the extrusion and pushing mechanism includes a second connecting frame, a rotating plate, a third compression spring, a roller, a connecting rod, a connecting block, a rotating block, a fourth compression spring, and rollers. The second connecting frame is connected to the first connecting frame on the left side. Two rotating plates are rotatably connected to the second connecting frame. A third compression spring is connected between each rotating plate and the second connecting frame. A connecting rod is rotatably connected between each rotating plate and the adjacent piston rod. Several rollers are rotatably connected to each rotating plate at intervals. Several connecting blocks are symmetrically connected at intervals on the mounting frame. A rotating block is rotatably connected to each connecting block. A fourth compression spring is connected between each rotating block and the mounting frame. Rollers are rotatably connected to each rotating block. When the rotating plate moves to the left, it will contact the adjacent roller.

[0008] Optionally, the material blocking mechanism includes an extrusion rod, a baffle plate, a sliding rod, a fifth compression spring, and a rotating rod. Several extrusion rods are symmetrically spaced at intervals on the mounting frame. A baffle plate for blocking the material is slidably connected to the feeding box. The baffle plate blocks the first circular hole. Several second circular holes are arrayed on the baffle plate, and the second circular holes correspond one-to-one with the first circular holes. Two sliding rods are connected to the baffle plate, and both sliding rods are slidably connected to the feeding box. A fifth compression spring is connected between each sliding rod and the feeding box. Two rotating rods are rotatably connected to the feeding box, and each rotating rod is movably connected to the adjacent sliding rod. When the rotating rod moves to the left, it will contact the adjacent extrusion rod.

[0009] Optionally, it also includes a crushing mechanism, which includes a feed hopper, a motor and a crushing blade. The feed hopper is connected between two first connecting frames.

[0010] Optionally, it also includes a feeding control mechanism, which includes a discharge block, a blocking block, and a sixth compression spring. Two discharge blocks are connected to the pressure plate. The discharge blocks are located directly above the adjacent feed pumps. Each discharge block has two discharge holes. A blocking block for blocking the feed is slidably connected to each discharge block. The blocking blocks are located inside the feed hopper. A sixth compression spring is connected between the blocking block and the adjacent discharge block. The blocking blocks abut against the adjacent feed pumps.

[0011] Optionally, it also includes cutting ropes, with several cutting ropes connected at intervals on the feeding box for cutting and scraping off residual food, all of which are located below the baffle plate.

[0012] Optionally, all rotating plates are tilted.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention controls the electric slide rail to drive the feeding box, rotating plate and rotating rod to move to the left. When the rotating rod contacts the extrusion rod, it will cause the baffle plate to move to the left. When the rotating plate contacts the roller, air will enter the connecting cylinder under the action of the connecting rod and the piston rod. When the rotating plate separates from the roller, the piston rod can squeeze the air in the connecting cylinder into the connecting box, causing the extrusion plate to move downward, thereby automatically feeding the fly larvae in the breeding frame in a quantitative manner.

Detailed Implementation

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1

[0028] A quantitative feeder for fly larvae farming, such as Figures 1-7As shown, the system includes a mounting frame 1, an electric slide rail 3, a feeding box 4, a first connecting frame 5, a guide rod 6, a first compression spring 7, a pressing plate 8, a feeding pump 81, a quantitative pressing mechanism 9, a squeezing and pushing mechanism 10, and a blocking mechanism 11. Several breeding frames 2 are placed at intervals at the bottom of the mounting frame 1. An electric slide rail 3 is installed at the bottom of the mounting frame 1, and the feeding box 4 is connected to the electric slide rail 3. Several first circular holes 41 are arranged at intervals at the bottom of the feeding box 4. The first connecting frame 5 is symmetrically welded to the top of the feeding box 4. Guide rods are symmetrically slidably connected to the bottom of each first connecting frame 5. A first compression spring 7 is connected between rod 6, guide rod 6 and the adjacent first connecting frame 5. A pressing plate 8 is welded between the four guide rods 6. When the pressing plate 8 moves downward, it can press the feed in the feeding box 4 into the breeding frame 2. The pressing plate 8 is slidably connected to the feeding box 4. A feed pump 81 is symmetrically installed on the pressing plate 8. By controlling the feed pump 81, the feed can be transported into the feeding box 4. The quantitative pressing mechanism 9 is used to quantitatively press the feed. The first connecting frame 5 on the left is provided with a squeezing and pushing mechanism 10, and the feeding box 4 is provided with a blocking mechanism 11.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the quantitative pressing mechanism 9 includes a connecting box 91, a piston column 92, an electric exhaust valve 93, a connecting cylinder 94, a one-way vent pipe 95, a one-way valve 96, a piston rod 97, and a second compression spring 98. Connecting boxes 91 are symmetrically welded between two first connecting frames 5. A piston column 92 is slidably connected inside each connecting box 91, and each piston column 92 is in sealed contact with the adjacent connecting box 91. The bottom of each piston column 92 is welded to the pressing plate 8. An electric exhaust valve 93 is installed on the top of each connecting box 91. A connecting cylinder 94 is connected to the left side of each connecting box 91. One-way vent pipes 95 symmetrically connect the connecting cylinder 94 to the adjacent connecting box 91. One-way valves 96 are installed on the top left side of each connecting cylinder 94. Piston rods 97 are slidably connected to each connecting cylinder 94. The piston rods 97 are in sealed contact with the adjacent connecting cylinders 94. When the piston rods 97 move to the right, air enters the connecting cylinder 94 through the one-way valves 96. When the piston rods 97 move to the left, they compress the air into the one-way vent pipe 95, allowing the air to enter the connecting box 91. This drives the piston column 92 and the pressure plate 8 to move downwards, thereby feeding the fly larvae quantitatively through the pressure plate 8. The piston rods 97 extend from the left side of the adjacent connecting cylinders 94. A second compression spring 98 is connected between the piston rods 97 and the adjacent connecting cylinders 94.

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the extrusion and pushing mechanism 10 includes a second connecting frame 101, a rotating plate 102, a third compression spring 103, a roller 104, a connecting rod 105, a connecting block 106, a rotating block 107, a fourth compression spring 108, and a roller 109. The second connecting frame 101 is welded to the upper part of the first connecting frame 5 on the left side. The rotating plate 102 is symmetrically and rotatably connected to the second connecting frame 101. The rotating plates 102 are all inclined. A third compression spring 103 is connected between each rotating plate 102 and the second connecting frame 101. A connecting rod 105 is rotatably connected between each rotating plate 102 and the adjacent piston rod 97. Several rollers are rotatably connected at intervals on the top of the rotating plate 102. The roller 104 and the mounting frame 1 have several connecting blocks 106 symmetrically welded to the upper part at intervals. Each connecting block 106 is rotatably connected to a rotating block 107. Each rotating block 107 is connected to the mounting frame 1 via a fourth compression spring 108 on its right side. Each rotating block 107 is rotatably connected to a roller 109 at its lower part. When the rotating plate 102 moves to the left, it will contact the adjacent roller 109, causing the rotating plate 102 to rotate downward. Under the action of the connecting rod 105, it pushes the piston rod 97 to move to the right. When the rotating plate 102 separates from the roller 109, under the action of the third compression spring 103, the rotating plate 102 will rotate upward, thereby causing the piston rod 97 to move to the left via the connecting rod 105.

[0031] like Figure 1 , Figure 2 and Figure 7 As shown, the material blocking mechanism 11 includes a pressing rod 111, a baffle plate 112, a sliding rod 114, a fifth compression spring 115, and a rotating rod 116. Several pressing rods 111 are symmetrically welded to the lower part of the mounting frame 1 at intervals. A baffle plate 112 is slidably connected to the bottom of the feeding box 4, blocking the first circular hole 41. Several second circular holes 113 are arrayed on the baffle plate 112, each corresponding to a first circular hole 41. When all the second circular holes 113 are aligned with their corresponding first circular holes 41, the pressure plate 8 moves downwards to discharge the material. When the food in box 4 is extruded, if the second round hole 113 is not aligned with the corresponding first round hole 41, the baffle plate 112 will block the food in the feeding box 4. The baffle plate 112 has symmetrical sliding rods 114 welded to the front and back on the right side. The sliding rods 114 are all slidably connected to the feeding box 4. A fifth compression spring 115 is connected between the sliding rods 114 and the feeding box 4. The feeding box 4 has symmetrical rotating rods 116 rotatably connected to the front and back on the right side. The rotating rods 116 are all movably connected to the adjacent sliding rods 114. When the rotating rods 116 move to the left, they will contact the adjacent extrusion rods 111.

[0032] First, a suitable amount of food is loaded into the feed hopper 4 by the feed pump 81. The baffle plate 112 blocks the first round hole 41 to prevent the food from falling out. The feed hopper 4 is driven to the left by the electric slide rail 3, which in turn drives the first connecting frame 5, the pressure plate 8, the connecting box 91, the connecting cylinder 94, the second connecting frame 101, the rotating plate 102, the roller 104, and the rotating rod 116 to the left. When the rotating rod 116 contacts the pressing rod 111, the pressing rod 111 will press the rotating rod 116 to rotate clockwise, which will drive the sliding rod 114 to move to the left. The fifth compression spring 115 is compressed, which will drive the baffle plate 112 to move to the left. When the rotating plate 102 contacts the roller 109, the roller 109 will press the rotating plate 102 to rotate downwards. 9 rotates under the action of friction, and the third compression spring 103 is compressed. When the roller 104 contacts the roller 109, the roller 104 will rotate under the action of friction, which can reduce friction. The rotating plate 102 rotates downward, which will drive the connecting rod 105 to rotate. Thus, under the action of the connecting rod 105, the piston rod 97 is pushed to the right. The second compression spring 98 is stretched, which allows air to enter the connecting cylinder 94 through the one-way valve 96. When the rotating plate 102 separates from the roller 109, the third compression spring 103 returns to its original state, driving the rotating plate 102 to rotate upward and reset. Thus, under the action of the connecting rod 105, the piston rod 97 moves to the left. The second compression spring 98 returns to its original state, and the leftward movement of the piston rod 97 can allow the air in the connecting cylinder 94 to pass through. The feed is squeezed through the one-way ventilation pipe 95 into the connecting box 91, thereby pushing the piston column 92 downward, driving the pressure plate 8 and guide rod 6 downward, and compressing the first compression spring 7. At this time, the baffle plate 112 moves to the left, causing the second round hole 113 to align with the corresponding first round hole 41. The feeding box 4 is located directly above the right-side breeding frame 2, so the feed plate 8 squeezes the feed in the feeding box 4 into the right-side breeding frame 2 in a measured amount. When the rotating rod 116 separates from the extrusion rod 111, the fifth compression spring 115 returns to its original state, driving the sliding rod 114 and the baffle plate 112 to move to the right to reset, thereby driving the rotating rod 116 to rotate counterclockwise to reset, so that the second round hole 113 is no longer aligned with the corresponding first round hole 41, and the baffle plate 112... The feeding will be blocked again. Similarly, when the feeding box 4, the first connecting frame 5, the pressing plate 8, the connecting box 91, the connecting cylinder 94, the second connecting frame 101, the rotating plate 102, the roller 104, and the rotating rod 116 continue to move to the left, the rotating rod 116 will contact the next pressing rod 111, so that the second round hole 113 is aligned with the corresponding first round hole 41. When the rotating plate 102 contacts the next roller 109, air will re-enter the connecting cylinder 94. When the rotating plate 102 separates from the roller 109, the pressing plate 8 can move downward again to press the feed, thereby quantitatively feeding the fly larvae in the next breeding frame 2. After the feed in the feeding box 4 is finished, the feeding box 4 is driven to move to the right to reset by controlling the electric slide rail 3.The first connecting frame 5, the pressing plate 8, the connecting box 91, the connecting cylinder 94, the rotating plate 102, the roller 104, and the rotating rod 116 move to the right to reset. When the rotating plate 102 contacts the rotating block 107, the rotating plate 102 will squeeze the rotating block 107 to rotate counterclockwise, and the fourth compression spring 108 will be compressed. When the rotating plate 102 passes the rotating block 107, the fourth compression spring 108 returns to its original state, driving the rotating block 107 to rotate clockwise to reset. Then, the electric exhaust valve 93 is controlled to discharge the air in the connecting box 91, the first compression spring 7 returns to its original state, and the guide rod 6 and the pressing plate 8 move upward to reset. Then, the feed pump 81 can load the feed into the feeding box 4 again. In this way, the fly larvae in the breeding frame 2 can be automatically fed in a quantitative manner, improving work efficiency.

[0033] Example 2

[0034] Based on Example 1, such as Figure 1 , Figure 2 and Figure 8 As shown, it also includes a crushing mechanism 12, which includes a feed hopper 121, a motor 123, and a crushing blade 124. The feed hopper 121 is welded between the two first connecting frames 5. The top of the feed hopper 121 has a feed hole 122. The motor 123 is bolted to the bottom of the feed hopper 121. The output shaft of the motor 123 is connected to the crushing blade 124 through a coupling. When the crushing blade 124 rotates, it can crush and stir the food in the feed hopper 121, thereby improving the utilization rate of the food.

[0035] like Figure 2 , Figure 9 and Figure 10 As shown, it also includes a feeding control mechanism 13, which includes a discharge block 132, a blocking block 134, and a sixth compression spring 135. The discharge blocks 132 are symmetrically welded on the front and back of the pressure plate 8. The discharge blocks 132 are all located directly above the adjacent conveying pumps 81. The discharge holes 133 are symmetrically opened on the left and right sides of the discharge blocks 132. When the discharge holes 133 are not blocked, the food in the feed barrel 121 can enter the discharge holes 133, so that the food can be conveyed by the conveying pumps 81. The blocking blocks 134 are slidably connected to the discharge blocks 132. The blocking blocks 134 are all located inside the feed barrel 121. The sixth compression spring 135 is connected between the blocking blocks 134 and the adjacent discharge blocks 132. The bottom of the blocking blocks 134 abuts against the adjacent conveying pumps 81. When the blocking blocks 134 move downward, they will block the adjacent discharge holes 133.

[0036] Initially, the sixth compression spring 135 is in a stretched state. When food needs to be loaded into the feeding box 4, it is fed into the feeding barrel 121 through the feeding hole 122. Then, the control motor 123 drives the crushing blade 124 to rotate. The crushing blade 124 can crush larger materials in the food and also stir the food, thereby improving the utilization rate of the food. At this time, the crushed and stirred food will enter the discharge hole 133, and then the feeding pump 81 will transport the food in the feeding barrel 121 to the feeding box 4. When the pressing plate 8 moves downward to press the food, it drives the feeding pump 81 to... The downward movement separates the feed pump 81 from the blockage block 134, and the sixth compression spring 135 returns to its original state, driving the blockage block 134 to move downward. The blockage block 134 can block the discharge hole 133, thereby controlling the amount of feed in the feeding box 4. When the pressure plate 8 moves upward, it drives the feed pump 81 to move upward. When the feed pump 81 comes into contact with the blockage block 134, the feed pump 81 will squeeze the blockage block 134 to move upward. The sixth compression spring 135 is compressed, so that the blockage block 134 no longer blocks the discharge hole 133, so that the feed pump 81 can feed the feeding box 4 again.

[0037] like Figure 11 As shown, it also includes a cutting rope 14. Several cutting ropes 14 are connected at intervals at the bottom of the feeding box 4. The cutting ropes 14 are all located below the baffle plate 112. When the baffle plate 112 moves to the right to reset, the cutting ropes 14 will move to the left relative to the baffle plate 112. The cutting ropes 14 can cut and scrape off the food remaining on the baffle plate 112, so that the food falls into the breeding frame 2, reducing the waste of food.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
