Description

Feeding mechanism of insect breeding system Technical Field

[0001] The invention belongs to the technical field of breeding equipment and relates to a feeding mechanism of an insect breeding system. Background Art

[0002] With the development of society, the current breeding industry is not only aimed at the breeding of animals and aquatic products. The breeding of insects has also gradually begun to rise, such as the breeding of silkworm pupae, the breeding of flies, etc., and modern insect breeding systems have gradually replaced traditional artificial breeding.

[0003] For example, a Chinese patent application (application number: 201811651751.4) discloses an insect breeding equipment, including a frame, on which a multi-layer belt conveyor mechanism is provided. The two adjacent layers of belt conveyor mechanisms have opposite operating directions, and a transfer mechanism is provided between the two adjacent layers of belt conveyor mechanisms for transferring materials from the upper belt conveyor mechanism to the lower belt conveyor mechanism; above each layer of belt conveyor mechanism is provided a feeding mechanism for supplementing nutrients to the belt conveyor mechanism, the feeding mechanism includes a nutrient conveying mechanism and a feeding mechanism for conveying nutrients to the nutrient conveying mechanism, the nutrient conveying mechanism includes a nutrient conveying pipe arranged along the length direction of the belt conveyor mechanism and an auger arranged in the nutrient conveying pipe, the auger extends into the feeding mechanism, and the lower surface of the nutrient conveying pipe is provided with a plurality of material boxes distributed along its length direction, and the lower end of each material box forms a discharge port, and each discharge port is square. The specific insect breeding method of this insect breeding equipment is: starting the belt conveyor mechanisms on each layer, inputting nutrients and insect eggs at the transmission starting end of the belt conveyor mechanism on the top layer, and continuously adding nutrients to the belt conveyor mechanism through the feeding mechanism to form a nutrient layer covering the insect eggs, thereby ensuring that the eggs have sufficient nutrients throughout the entire growth cycle. The time from the transmission starting end of the belt conveyor mechanism on the top layer to the transmission end of the belt conveyor mechanism on the bottom layer is consistent with the cycle of the insect eggs growing into adults.

[0004] The above-mentioned insect-rearing equipment has the following drawbacks: Nutrients are first delivered to the nutrient delivery pipe by a feeding mechanism, and then delivered to the corresponding belt conveyor mechanism on each layer through various discharge ports arranged along the length of the nutrient delivery pipe. A nutrient pile is formed on the belt conveyor mechanism. As each belt conveyor mechanism runs, a linear nutrient pile is formed to cover the insect eggs. Because the discharge ports are distributed along the length of the belt conveyor mechanism, the nutrient pile formed is uneven in thickness, with some areas being too thick, affecting the normal growth of the insect eggs. Furthermore, the formed nutrient pile can result in excessive coverage, leading to oxygen deprivation for the insect eggs, affecting their normal growth.

[0005] In order to ensure that the eggs can grow normally, the conventional practice in this field is to precisely control the nutrients added from the outlet of each feed box so that the nutrients are fed into the belt conveyor mechanism to form a uniform nutrient layer.

[0006] Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a feeding mechanism for an insect breeding system. The technical problem to be solved by the present invention is: how to solve the problem of uneven nutrient spreading and high covering density in the existing technology.

[0008] The objectives of the present invention can be achieved through the following technical solutions: a feeding mechanism for an insect breeding system, the breeding system includes a frame and a multi-layer breeding conveyor belt arranged on the frame, each layer of the breeding conveyor belt is provided with the above-mentioned feeding mechanism, the feeding mechanism includes a material box and a feeding device for conveying nutrients into the material box, and is characterized in that the material box is arranged above the input end of the corresponding breeding conveyor belt, the material box has several discharge ports arranged toward the breeding conveyor belt, the several discharge ports are distributed along the width direction of the breeding conveyor belt, and the material box can move back and forth relative to the breeding conveyor belt along the width direction of the breeding conveyor belt.

[0009] Through improved design, this feeding mechanism directly cancels the nutrient delivery pipe above each layer of the breeding conveyor belt, and reduces the material box on each layer of the breeding conveyor belt to one set above the input end of the breeding conveyor belt, and also sets multiple discharge ports of each material box, reducing the diameter of a single discharge port, so that after the material box is discharged, a row of dense point-shaped nutrients can be formed on the breeding conveyor belt. At the same time, the material box can move back and forth along the width direction of the breeding conveyor belt, so that a staggered state can be formed between two adjacent rows of point-shaped nutrients. As the breeding conveyor belt runs, a dense point-shaped rectangular array nutrient layer is formed on the breeding conveyor belt. That is to say, the present application uses the above-mentioned setting in conjunction with the operation of the breeding conveyor belt so that the entire nutrient layer is formed by the discharge of the same material box, ensuring the uniformity of the material laying. At the same time, the nutrient layer formed is distributed in a point-shaped rectangular array, and there is a staggered arrangement between the two adjacent rows of point-shaped nutrients, ensuring that the two rows of point-shaped nutrients are relatively compact and dense while also allowing a tiny gap to be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding oxygen deficiency for the insect eggs and ensuring that the insect eggs can grow normally. Moreover, the present application eliminates the structure of the nutrient delivery pipe, and the nutrients are directly delivered to the material box through the feeding equipment, which does not cause the nutrients to accumulate on the nutrient delivery pipe, reduces the nutrient delivery path, and reduces energy consumption.

[0010] In the feeding mechanism of the aforementioned insect breeding system, the feeding device is connected to the feed box via a feeding tube. The feeding tube has a retractable bellows section that extends along the width of the breeding conveyor belt. The frame is provided with a drive member, the driving end of which is connected to the feed box and capable of driving the feed box back and forth along the width of the breeding conveyor belt. The feeding device delivers nutrients into the feed box through the feeding tube. The nutrients are discharged through the feed box's outlet, forming a dense row of nutrient points on the breeding conveyor belt. The drive member drives the feed box back and forth, creating a misalignment between adjacent rows of nutrient points, thereby forming a slight gap between each nutrient point. This keeps the density of the entire nutrient layer moderate, preventing oxygen deprivation for the insect eggs and ensuring normal growth. The bellows section on the feeding tube ensures the normal back-and-forth movement of the feed box without affecting the seal between the feeding tube and the feed box.

[0011] In the feeding mechanism of the above-mentioned insect breeding system, the discharge port is opened at the bottom end of the feed box, and the volume of the inner cavity of the feed box gradually decreases from top to bottom. Through this arrangement, the nutrients can be gradually concentrated and compacted toward the lower end of the feed box after entering the feed box, while also achieving a pressurization process, so that the nutrients will not become loose when they fall onto the breeding conveyor belt after being discharged from the discharge port, thereby better forming a row of regular and uniform nutrient points on the breeding conveyor belt, further ensuring the uniformity of the material laying, and also better ensuring that a slight gap can be formed between each nutrient point, so that the density of the entire nutrient layer is not too high, avoiding hypoxia of the insect eggs and ensuring that the insect eggs can grow normally.

[0012] In the feeding mechanism of the above-mentioned insect breeding system, the feed box is in the shape of a flat box with an opening at the bottom. The feed box has a side panel portion 1 and a side panel portion 2, both of which are arranged along the width direction of the breeding conveyor belt. The side panel portion 1 and the side panel portion 2 are arranged opposite each other. The bottom end of the side panel portion 1 is hingedly connected to the side panel portion 3. The side panel portion 2 has a plurality of partition portions protruding toward the side panel portion 3. The plurality of partition portions are distributed along the width direction of the breeding conveyor belt. The feed box is also provided with an elastic member that always presses the side panel portion 3 against the partition portion, and the aforementioned opening is separated by the aforementioned partition portion to form the aforementioned plurality of discharge ports. During normal use, the feeding equipment feeds nutrients into the feed box at a normal rate. Under the action of the elastic member, the side panel portion 3 always presses against the partition portion, and the nutrients are discharged from the discharge port, forming a dense, dot-shaped rectangular array of nutrients on the breeding conveyor belt. When breeding insects that do not require such high oxygen content but have relatively high demands for nutrients, the rate at which the feeding equipment delivers nutrients to the material box can be increased. As the amount of nutrients delivered to the material box per unit time increases, the pressure in the material box becomes greater. The increased pressure can slightly overcome the elastic force of the elastic part, causing the third side panel to swing slightly upward around the hinge point, forming a tiny gap between the partition part. Most of the nutrients are discharged from the discharge port to form a dense dot-shaped rectangular array nutrient layer, while a small amount of nutrients are discharged from the gap between the third side panel and the partition part, so that a thin sheet-like nutrient layer can be laid on top of the dot-shaped rectangular array nutrient layer, which is suitable for the growth habits of the above-mentioned insects.

[0013] In the feeding mechanism of the aforementioned insect breeding system, the surfaces of the several partitions are flush with the bottom end surfaces of the second and third side panels, and the partitions are arranged at an angle relative to the breeding conveyor belt. This arrangement ensures that the nutrient discharge direction is opposite to the running direction of the breeding conveyor belt, thereby reducing the spacing between the rows of nutrient dots formed on the breeding conveyor belt. This effectively forms a dense rectangular array of nutrient dots, ensuring that there are fine gaps between them while still providing sufficient nutrients for the insect eggs, ensuring their normal growth.

[0014] In the feeding mechanism of the aforementioned insect breeding system, the feed box further comprises two opposing connecting plates, which connect side plate portion 1 and side plate portion 2. Side plate portion 3 comprises a first lug, and one of the connecting plates comprises a second lug. The elastic member is a tension spring, with its ends connected to lug 1 and lug 2, respectively. Side plate portion 3, under the action of the elastic member, presses against the sides of the two connecting plates. The arrangement of lugs 1 and 2 stabilizes the tension spring on the feed box, thereby stabilizing the force applied to side plate portion 3.

[0015] Alternatively, in the feeding mechanism of the insect farming system described above, the feeding device is connected to a feeding tube arranged along the width of the farming conveyor belt. The feeding tube slides into the feed box and has two annular retaining edges spaced apart along the length of the feeding tube. The two annular retaining edges are located on the inner and outer sides of the feed box, respectively. Each annular retaining edge is provided with a sealing ring surrounding the feeding tube. The frame is provided with a driving member, the driving end of which is connected to the feed box and is capable of driving the feed box back and forth along the width of the farming conveyor belt. The feeding device delivers nutrients into the feed box through the feeding tube. The nutrients are discharged through the feed box's discharge port, forming a dense row of nutrient points on the farming conveyor belt. The driving member drives the feed box back and forth, creating a misalignment between adjacent rows of nutrient points, thereby forming a slight gap between each nutrient point. During the back-and-forth movement of the feed box, the two annular retaining edges respectively abut against the outer wall or inner wall of the feed box to achieve a seal.

[0016] In the feeding mechanism of the insect breeding system, the side walls of the feed box and the two annular retaining edges opposite each other are each provided with an annular groove, and the sealing rings on the two annular retaining edges can be inserted into the corresponding annular grooves and pressed against the inner walls of the annular grooves to achieve a seal. This arrangement can provide a sealing effect.

[0017] In the feeding mechanism of the aforementioned insect farming system, the frame is equipped with a guide rod extending along the width of the farming conveyor belt. A slider is fixed to the feed box, which has a guide groove into which the guide rod is inserted. The guide rod has a small spherical bump located on one side of the slider. The coordinated arrangement of the guide rod and the slider guides the feed box's movement, preventing it from shifting and ensuring a uniform layer of nutrient material in the resulting rectangular array of dots. The setting of the small spherical bumps allows the material box to pass through the small bumps during the back and forth movement. Due to the height difference, the material barrel can shake up and down, which is equivalent to an acceleration formed by the downward swing of the discharged nutrients, reducing the time the nutrients stay in the air so that they will not become loose, thereby forming a row of regular and uniform point-shaped nutrients on the breeding conveyor belt, further ensuring the uniformity of the material laying, and better ensuring that a slight gap can be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding hypoxia of the insect eggs and ensuring the normal growth of the insect eggs.

[0018] The purpose of the present invention can also be achieved through the following technical solutions: a feeding mechanism of an insect breeding system, the breeding system includes a frame and a multi-layer breeding conveyor belt arranged on the frame, each layer of the breeding conveyor belt is provided with the above-mentioned feeding mechanism, the feeding mechanism includes a material box and a feeding device for conveying nutrients into the material box, and is characterized in that the material box is arranged above the input end of the corresponding breeding conveyor belt, and the material box has several discharge ports arranged toward the breeding conveyor belt, and the several discharge ports are distributed along the width direction of the breeding conveyor belt.

[0019] Through improved design, this feeding mechanism directly cancels the nutrient delivery pipe above each layer of the breeding conveyor belt, and reduces the material box on each layer of the breeding conveyor belt to one set above the input end of the breeding conveyor belt, and also sets the discharge port of each material box to multiple, reducing the diameter of a single discharge port, so that after the material box is discharged, a row of dense point-shaped nutrients can be formed on the breeding conveyor belt. As the breeding conveyor belt runs, a relatively dense point-shaped rectangular array nutrient layer is formed on the breeding conveyor belt. In other words, this application uses the above-mentioned setting to cooperate with the operation of the breeding conveyor belt, so that the entire nutrient layer is formed by the discharge of the same material box, ensuring the uniformity of the material laying, and the formed nutrient layer is distributed in a point-shaped rectangular array, so that a slight gap can be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding hypoxia of the insect eggs, and ensuring that the insect eggs can grow normally. Moreover, the present application eliminates the structure of the nutrient delivery pipe, and the nutrients are directly delivered to the material box through the feeding equipment, which will not cause the nutrients to accumulate on the nutrient delivery pipe, and also reduces the nutrient delivery path and reduces energy consumption.

[0020] Compared with the existing technology, the feeding mechanism of this insect breeding system has the following advantages:

[0021] 1. The entire nutrient layer is formed by the discharge of materials from the same material box, ensuring the uniformity of the material laying. At the same time, the formed nutrient layer is distributed in a dot-shaped rectangular array, and there is a staggered arrangement between two adjacent rows of dot-shaped nutrients. This ensures that the two rows of dot-shaped nutrients are relatively compact and dense, while also allowing a tiny gap to be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding oxygen deprivation for the insect eggs and ensuring that the insect eggs can grow normally.

[0022] 2. The structure of the nutrient delivery pipe is eliminated, and the nutrients are directly delivered to the material box through the feeding equipment, which will not cause the nutrients to accumulate on the nutrient delivery pipe, and also reduces the nutrient delivery path and reduces energy consumption.

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0034] Example 1

[0035] As shown in Figure 1, this insect breeding system is a digital breeding system, which includes a frame 1 and a multi-layer breeding conveyor belt 2 arranged on the frame 1. The conveying directions of the two adjacent breeding conveyor belts 2 are opposite. A transfer mechanism is provided between the two adjacent breeding conveyor belts 2 for transferring the insect eggs and the like on the upper breeding conveyor belt 2 to the lower breeding conveyor belt 2. The input end of the uppermost conveyor belt is connected to the feeding mechanism, and the output end of the lowermost conveyor belt is connected to the discharging mechanism. Each layer of breeding conveyor belt 2 is provided with a feeding mechanism for adding nutrients required for the growth of insect eggs to the breeding conveyor belt 2.

[0036] Specifically, as shown in Figure 2, the feeding mechanism includes a material box 3 and a feeding device 4 for conveying nutrients into the material box 3. In this embodiment, the feeding device 4 is an electric valve, and the material box 3 is arranged above the input end corresponding to the breeding conveyor belt 2. The material box 3 has several discharge ports 3a arranged toward the breeding conveyor belt 2. The discharge ports 3a are opened at the bottom end of the material box 3. The volume of the inner cavity of the material box 3 gradually decreases from top to bottom. Several discharge ports 3a are distributed along the width direction of the breeding conveyor belt 2, and the material box 3 can move back and forth relative to the breeding conveyor belt 2 along the width direction of the breeding conveyor belt 2.

[0037] Specifically, as shown in Figures 4, 5, and 6, the material box 3 is a flat box with an open bottom. The material box 3 comprises a top panel 3g, a rear side panel 3j, a side panel 1 3b and a side panel 2 3c, both arranged along the width of the aquaculture conveyor belt 2, and two opposing connecting panels 3f. The upper side of the rear side panel 3j is connected to the rear side of the top panel 3g, the top end of the side panel 1 3b is connected to the front side of the top panel 3g, and one end of the side panel 2 3c is connected to the lower side of the rear side panel 3j. The two connecting panels 3f are both connected and fixed to the top panel 3g, the rear side panel 3j, and the side panels 1 3b and 2 3c. The side panels 1 3b and 2 3c are arranged opposite each other. The bottom end of the side panel 1 3b is hingedly connected to the side panel 3 3d. The side panel 2 3c has a plurality of partition panels 3e protruding toward the side panel 3 3d. The partition panels 3e are distributed along the width of the aquaculture conveyor belt 2. The feed box 3 is also equipped with an elastic member 7, which is a tension spring. Side panel portion 3d has a first lug 3d1, and one of the connecting panel portions 3f has a second lug 3f1. The ends of the tension spring are connected to the first lug 3d1 and the second lug 3f1, respectively. Under the action of the elastic member 7, side panel portion 3d is always pressed against the sides of each partition portion 3e and the two connecting panel portions 3f. The partition portions 3e separate the openings to form the plurality of discharge ports 3a. The surfaces of the partition portions 3e are flush with the bottom ends of side panel portion 2 3c and side panel portion 3d, and the partition portions 3e are arranged at an angle relative to the farming conveyor belt 2.

[0038] As shown in Figures 2 and 3, the feeding device 4 is connected to the material box 3 via a feeding pipe 5. The feeding pipe 5 has a retractable bellows section 5a, which is arranged along the width direction of the breeding conveyor belt 2. The frame 1 is provided with a driving member 6, the driving end of which is connected to the material box 3 and can drive the material box 3 to move back and forth along the width direction of the breeding conveyor belt 2. In this embodiment, the driving member 6 is a cylinder, the cylinder body of the cylinder is fixed to the frame 1, the piston rod of the cylinder is arranged along the width direction of the breeding conveyor belt 2, and the piston rod of the cylinder is fixedly connected to the material box 3. The material box 3 is driven to move back and forth along the width direction of the breeding conveyor belt 2 by the extension and contraction of the cylinder piston rod.

[0039] Furthermore, as shown in Figures 3 and 7, the frame 1 is provided with a guide rod 9 arranged along the width direction of the breeding conveyor belt 2, and a sliding member 10 is fixed on the material box 3. The sliding member 10 has a guide groove 10a, and the guide rod 9 is embedded in the guide groove 10a. The thickness of the sliding member 10 along the length direction of the guide rod 9 is relatively small, and the guide rod 9 has a small spherical bump 11, which is located on one side of the sliding member 10.

[0040] The working principle of this feeding mechanism is: the feeding device 4 maintains a normal conveying speed to transport the nutrients (also called feed) required for the growth of insect eggs into the material box 3 through the feeding pipe 5, the breeding conveyor belt 2 runs synchronously, and the side plate part 3d is always pressed against the partition part 3e and the connecting plate part 3f under the action of the elastic member 7. At the same time in this process, the driving member 6 runs and drives the material box 3 to move back and forth along the width direction of the breeding conveyor belt 2 under the cooperation of the guide rod 9 and the sliding member 10. The material box 3 can pass through the small protrusion 11 during the back and forth movement. Due to the existence of the height difference, the material box 3 can shake up and down, which is equivalent to the discharged nutrients having a downward acceleration, reducing the time the nutrients stay in the air so that they will not become loose. The nutrients fall from each discharge port 3a onto the breeding conveyor belt 2, thereby forming rows of dense point-shaped nutrients on the breeding conveyor belt 2, and a dislocation can be formed between adjacent rows of point-shaped nutrients, which is equivalent to laying a dense point-shaped rectangular array nutrient layer above the insect eggs on the breeding conveyor belt 2, providing the nutrients required for the growth of the insect eggs. When breeding insects that do not require such high oxygen content but have relatively high demand for nutrients, the rate at which the feeding device 4 delivers nutrients to the material box 3 can be increased. Since the amount of nutrients delivered to the material box 3 per unit time increases, the pressure in the material box 3 becomes greater. The increased pressure can slightly overcome the elastic force of the elastic member 7, causing the side panel portion 3d to swing slightly upward around the hinge point and form a tiny gap between the partition portion 3e. Most of the nutrients are discharged from the discharge port 3a to form a dense dot-shaped rectangular array nutrient layer, while a small amount of nutrients are discharged from the gap between the side panel portion 3d and the partition portion 3e, so that a thin sheet-like nutrient layer can be laid on top of the dot-shaped rectangular array nutrient layer, which is suitable for the growth habit requirements of the above-mentioned insects.

[0041] This feeding mechanism directly eliminates the nutrient delivery pipe above each layer of the breeding conveyor belt 2, and reduces the material box 3 on each layer of the breeding conveyor belt 2 to a single one set above the input end of the breeding conveyor belt 2. The nutrients are directly delivered to the material box 3 through the feeding device 4, which does not cause the nutrients to accumulate on the nutrient delivery pipe, reduces the nutrient delivery path, reduces energy consumption, and makes the entire nutrient layer formed by the discharge of the same material box 3, ensuring the uniformity of the material laying. At the same time, the discharge port 3a of each material box 3 is set to multiple, reducing the diameter of a single discharge port 3a, and the formed nutrient layer is distributed in a point-shaped rectangular array, and there is a staggered gap between the two adjacent rows of point-shaped nutrients, ensuring that the two rows of point-shaped nutrients are relatively compact and dense, while also allowing a slight gap to be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding hypoxia of the insect eggs and ensuring that the insect eggs can grow normally.

[0042] Example 2

[0043] The structure and principle of the feeding mechanism of the insect breeding system of this embodiment are basically similar to those of Example 1, except that: as shown in Figure 8, the feeding device 4 is connected to a feeding pipe 5 arranged along the width direction of the breeding conveyor belt 2, and the feeding pipe 5 slides into the material box 3. The feeding pipe 5 has two annular retaining edges 5d spaced apart along the length direction of the feeding pipe 5, and the two annular retaining edges 5d are respectively located on the inner and outer sides of the material box 3. The two annular retaining edges 5d are each provided with a sealing ring 8 arranged around the feeding pipe 5, and the frame 1 is provided with a driving member 6. The driving end of the driving member 6 is connected to the material box 3 and can drive the material box 3 to move back and forth along the width direction of the breeding conveyor belt 2. The material box 3 has an annular groove 3g on the side wall opposite to the two annular retaining edges 5d. The sealing rings 8 on the two annular retaining edges 5d can be embedded in the corresponding annular groove 3g and pressed against the inner wall of the annular groove 3g to achieve sealing.

[0044] Example 3

[0045] The structure and principle of the feeding mechanism of the insect breeding system of this embodiment are basically similar to those of the first embodiment, except that: as shown in Figure 9, the feeding mechanism includes a feed box 3 and a feeding device 4 for conveying nutrients into the feed box 3. The feed box 3 is fixedly arranged above the input end of the breeding conveyor belt 2. The feed box 3 has a plurality of discharge ports 3a arranged toward the breeding conveyor belt 2, and the plurality of discharge ports 3a are distributed along the width direction of the breeding conveyor belt 2. This feeding mechanism directly eliminates the nutrient delivery pipe above each layer of the breeding conveyor belt 2 and reduces the feed box 3 on each layer of the breeding conveyor belt 2 to a single feed box arranged above the input end of the breeding conveyor belt 2. The nutrients are directly conveyed to the feed box 3 through the feeding device 4, which does not cause the nutrients to accumulate on the nutrient delivery pipe, reduces the nutrient delivery path, reduces energy consumption, and ensures that the entire nutrient layer is formed by the discharge of the same feed box 3, thereby ensuring the uniformity of the material laying. At the same time, each material box 3 is provided with multiple discharge ports 3a, reducing the diameter of a single discharge port 3a. The formed nutrient layer is distributed in a point-shaped rectangular array, so that a tiny gap can be formed between each nutrient point, so that the density of the entire nutrient layer is not too large, avoiding oxygen deficiency of the insect eggs and ensuring that the insect eggs can grow normally.
