Description

Conveyor belt mechanism of insect breeding equipment Technical Field

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

[0002] Insect farming can convert organic waste into high-protein feed with high economic value. Common insects currently raised include maggots, black soldier flies and mealworms. Organic waste is also called nutrients when raising insects, generally expired milk powder, apple pieces, etc.

[0003] With the development of mechanization and automation, insect farming is now usually carried out in an assembly line-style farming mode. For example, a fully automatic fly maggot farming machine [Announcement No.: CN202773792U] proposed in a Chinese patent document includes a farming box, in which multiple layers of conveyor belts for farming are arranged from top to bottom. These conveyor belts are staggered and run in opposite directions. In order to prevent the conveyor belt from sagging, rollers are also provided at the bottom of the conveyor belt. For example, a conveying structure suitable for insect breeding beds proposed in a Chinese patent document [Announcement No.: CN215754679U] includes an upper roller and a lower roller. The upper roller is supported by rolling support on the lower side of the upper half of the conveyor belt, and the lower roller is supported by rolling support on the lower side of the lower half of the conveyor belt. The driving wheel and the driven wheel are respectively arranged at both ends of the conveyor belt. There is rolling friction between the roller and the conveyor belt, which can reduce friction resistance.

[0004] In the coal mining industry, there is an air-suspended conveyor belt used to transport coal. Air lifts the conveyor belt, suspending it, preventing most of the conveyor belt's structure from contacting other parts, significantly reducing frictional resistance. For example, a Chinese patent document discloses an air-suspended conveyor belt device [Publication No.: CN109996746A] that includes a conveyor belt, a forward trough, a reciprocating trough, an air supply manifold, and a blower that pressurizes air into the air supply manifold. The forward trough is semi-circular, with the forward portion of the conveyor belt located above the forward trough. Air outlets are located at the bottom of the forward trough, spaced at regular intervals along the length of the forward trough. An air supply manifold is located below the forward trough, extending along the length of the forward trough. Each air supply manifold has a manifold chamber formed within it, connected to the air outlet. The manifold is provided with an air supply port that directs air pressurized from the blower into the manifold chamber. The air supply port is connected to the blower through piping, etc. When the blower is working, the air that is pressed from the blower to the manifold chamber through the piping is blown out from the air outlet to between the upper surface of the outward trough and the non-conveying surface of the outward portion of the conveyor belt, thereby causing the conveyor belt to suspend. Although this type of air-suspended conveyor belt device can greatly reduce frictional resistance, there are still problems when it is used directly for insect breeding. For example, when the conveyor belt is suspended, air will be blown out from below on both sides of the conveyor belt. When the insects raised on the conveyor belt move to the edges of the conveyor belt, they will be blown away by the air, causing the number of insects raised on the conveyor belt to continue to decrease. This will not only lead to a decrease in the yield of adult insects, but also the loss of insects will increase the breeding cost. In order to avoid the problem of air blowing away insects, affecting production and increasing costs, the current solution is to avoid the air-suspended conveyor belt and adopt the solution of using mature rollers or roller shafts to support the conveyor belt. Due to the existence of this problem, insect breeding on air-suspended conveyor belts has not yet been realized.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and propose a conveyor belt mechanism for insect breeding equipment, which solves the technical problem of how to reduce costs and increase output when breeding insects on an air suspension conveyor belt.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A conveyor belt mechanism for insect breeding equipment includes a conveyor belt, and a blowing assembly capable of blowing air upward is provided below the upper belt body of the conveyor belt. The characteristic is that baffles arranged along the length direction of the conveyor belt are fixed on both sides of the blowing assembly, and an insect blocking plate located above the conveyor belt is fixed to the inner side of each baffle. Each insect blocking plate is separately arranged from the corresponding baffle and forms a ventilation gap. The lower side of each insect blocking plate abuts against the upper belt body of the conveyor belt, and each baffle has a guide strip protruding inward and located above the insect blocking plate.

[0009] Nutrients and insects are laid on the upper surface of the upper belt body of the conveyor belt to feed the insects. Because the insect-blocking plate is located above the conveyor belt, and its lower side abuts against the upper belt body of the conveyor belt, the insect-blocking plate has a blocking effect on the insects and nutrients, preventing the insects from crawling out of the conveyor belt or being blown away by the air just blown from the two sides of the blowing assembly. This reduces the loss of insects during the feeding process, can reduce breeding costs and increase yields.

[0010] When pressurized air is blown upward through the blow assembly, it enters the space between the upper belt and the blow assembly, lifting the upper belt and suspending it. Because the insect deflector and its corresponding baffle are separated to form a ventilation gap, and the baffle has inwardly protruding guide strips located above the baffle, once the upper belt is suspended, air flows out from both sides of the blow assembly and into the ventilation gap between the baffle and the baffle. After flowing upward, the air is blocked and directed by the guide strips, directing it downward, blowing toward the nutrients and insects on the conveyor belt. After adopting the conveyor belt mechanism of the present insect breeding equipment, the air is not only used to suspend and lift the upper belt body of the conveyor belt, but also can be blown to the upper surface of the conveyor belt through the guidance of the baffle and the insect deflector to deliver fresh air to the insects and cool them down. The delivery of fresh air and the cooling of the insects can also reduce the loss of insect breeding, reduce breeding costs and increase production, that is, the air is used for two purposes in one. At the same time, the insect deflector and the baffle with the guide strip can not only be used to prevent the insects from crawling out of the conveyor belt, but also can guide the air and block and reduce the pressure of the air, so that the air is in a reduced pressure state when it is blown downward from the guide strip and will not blow the insects away, thereby achieving the goal of delivering fresh air and cooling the insects, that is, the coordinated structure of the insect deflector and the baffle also has the function of serving two purposes in one.

[0011] Therefore, the insect breeding equipment using the conveyor belt mechanism can reduce insect loss when breeding insects on an air suspension conveyor belt, and can achieve dual purposes of air and the insect baffle and the baffle matching structure, thereby reducing costs and increasing production.

[0012] In the above-mentioned conveyor belt mechanism of the insect farming equipment, the inner side of each guide bar is tilted downward. This can further guide the air toward the conveyor belt and further reduce the air resistance and pressure, providing air to cool the insects while preventing them from being blown away, which is beneficial for reducing costs and increasing production.

[0013] In the above-mentioned conveyor belt mechanism of the insect breeding equipment, each insect deflector has an inwardly protruding and downwardly inclined deflection strip on its upper side. This further guides air toward the conveyor belt and reduces air resistance and pressure, cooling the insects while preventing them from being blown away, thereby reducing costs and increasing production.

[0014] In the above-mentioned conveyor belt mechanism of the insect-raising equipment, the inner side of the convex strip has a downwardly protruding ridge. The ridge can improve the structural strength of the convex strip and ensure the air guide function of the convex strip to achieve air supply and cooling for the insects, which is conducive to reducing costs and increasing production.

[0015] In the conveyor belt mechanism of the aforementioned insect-raising equipment, the air blowing assembly includes an air duct and a support plate, both arranged along the length of the conveyor belt. The air duct is provided with several air holes arranged along the length of the conveyor belt. Two baffles are fixed to either side of the support plate, and the air duct is fixed at the center of the support plate. Both sides of the support plate have an upwardly inclined inclined portion. The arrangement of the support plate and air duct ensures that the air lifting force on the upper belt of the conveyor belt is evenly distributed, ensuring that the upper belt of the conveyor belt is suspended stably. The inclined portion can guide the air to flow between the baffle and the insect-blocking plate, while also having the effect of blocking and reducing the pressure of the air. This helps prevent insects from being blown away when the air is blown out of the retaining ribs, thereby reducing costs and increasing production.

[0016] In the conveyor belt mechanism of the above-mentioned insect breeding equipment, each insect guard plate includes a sealing strip and a main body plate, the sealing strip is made of rubber, the main body plate is made of hard plastic or metal material, the guard convex strip is integrally arranged on the upper side edge of the main body plate, and the sealing strip is integrally formed on the lower side edge of the main body plate, and the sealing strip elastically rests on the upper surface of the upper belt body of the conveyor belt.

[0017] The sealing strip is made of rubber and has a certain degree of elasticity. When the sealing strip contacts the upper belt body of the conveyor belt, it effectively seals the conveyor belt, preventing insects from crawling out from between the sealing strip and the conveyor belt, and preventing nutrients from overflowing from between the sealing strip and the conveyor belt. This reduces insect and nutrient losses, helping to reduce costs and increase production. The main plate is made of hard plastic or metal and has a certain degree of rigidity, thus forming a certain blocking and pressure-reducing effect on the flowing air. This helps prevent insects from being blown away when air flows out from the retaining ribs of the insect deflector plate, reducing insect losses, reducing costs and increasing production.

[0018] In the conveyor belt mechanism of the above-mentioned insect breeding equipment, the lower side edge of each main body plate has an inwardly inclined portion that protrudes inward and tilts downward, the sealing strip is fixed on the inwardly inclined portion, and the two side edges of the upper belt body of the conveyor belt extend respectively to be opposite to the corresponding inwardly inclined portion.

[0019] When the air lifts the upper belt body of the conveyor belt, the two side edges of the upper belt body of the conveyor belt can be in contact with the inward inclined part, thereby better forming a seal between the insect baffle and the upper belt body of the conveyor belt, preventing air from entering from between the insect baffle and the upper belt body of the conveyor belt to the upper surface of the conveyor belt and blowing away insects and nutrients, which is conducive to ensuring reduced costs and increased production.

[0020] In the aforementioned conveyor belt mechanism of the insect farming equipment, the lower side of each sealing strip is bent inward and overlaps the upper belt portion of the conveyor belt. This increases the contact area between the sealing strip and the upper belt portion, thereby improving sealing performance, reducing insect and nutrient loss, and thus reducing costs and increasing production.

[0021] In the aforementioned insect-rearing equipment, the support plates on either side of the air duct are tilted upward by 1-3 degrees from the inside out. This allows air to act on the upper portion of the conveyor belt, lifting it and evenly distributing nutrients and insects across the conveyor belt. This prevents the support plates on either side of the air holes from tilting too far, causing the insects and nutrients to slide into and concentrate in the center of the conveyor belt. This avoids insect loss caused by excessive concentration of nutrients and insects, helping to reduce costs and increase production.

[0022] In the above-mentioned conveyor belt mechanism of the insect breeding equipment, the lower side of each baffle protrudes downward from the support plate, and the lower side of each baffle is bent outward to form an outward curved strip. The outward curved strip can improve the structural strength of the baffle and make the baffle structure stable.

[0023] In the aforementioned conveyor belt mechanism of the insect farming equipment, a roller is disposed between the lower belt body of the conveyor belt and the air blowing assembly. The upper surface of the lower belt body of the conveyor belt abuts against the outer surface of the roller. The ends of the roller are respectively passed through corresponding baffles. There are multiple rollers arranged in sequence along the length of the conveyor belt. The rollers tension the conveyor belt, ensuring stable operation.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The coordinated structure between the baffle and the insect-blocking plate can not only block insects and nutrients, reducing the loss caused by insects crawling out, but also guide and reduce the pressure of the air, so that the air blown out from the blowing hole can not only be used to lift the upper belt body of the conveyor belt to achieve the suspension of the upper belt body of the conveyor belt, but also can be used to supply air and cool the reared insects, reducing the loss of insect breeding, thereby reducing costs and increasing production.

[0026] 2. The upper part of the conveyor belt can move in suspension, which can reduce friction resistance, thereby reducing the power loss of the conveyor belt movement and reducing breeding costs.

[0027] 3. The nutrients on the conveyor belt are generally located at the bottom, and the insects are located above the nutrients. After being blown out from the air holes, the air first passes through the conveyor belt, which can remove some of the heat on the conveyor belt. This not only cools the nutrients accumulated at the bottom, but also preheats the air, preventing the air temperature from being too low when blown out from the guide strip, which may affect the vitality of the insects, thereby ensuring the yield of adult insects.

DETAILED DESCRIPTION

[0035] 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.

[0036] As shown in Figure 1, a conveyor belt mechanism for insect breeding equipment includes a horizontally arranged conveyor belt 1. Both sides of the conveyor belt 1 are provided with baffles 4 arranged along the length direction of the conveyor belt 1, and the baffles 4 are installed vertically. A driving shaft 8 and a driven shaft 9 are provided at both ends of the conveyor belt 1. Both ends of the driving shaft 8 and the driven shaft 9 are passed through the corresponding baffles 4. The driving shaft 8 is connected to a motor, which is not shown in the figure. When the motor is working, it drives the conveyor belt 1 to move horizontally. An insect guard 5 is fixed on the inner side of each baffle 4. The insect guard 5 is located above the conveyor belt 1 and is installed vertically.

[0037] As shown in Figures 2 and 4 , an upward-blowing air blowing assembly 2 is located beneath the upper belt body 1a of the conveyor belt 1. The air blowing assembly 2 includes an air duct 2c and a support plate 2a, both extending along the length of the conveyor belt 1. Two baffles 4 are fixed to either side of the support plate 2a, with the air duct 2c fixed at the center of the support plate 2a. A roller 7, extending along the width of the conveyor belt 1, is located between the lower belt body 1b of the conveyor belt 1 and the support plate 2a. The upper surface of the lower belt body 1b of the conveyor belt 1 abuts against the outer surface of the roller 7, with each end of the roller 7 passing through a corresponding baffle 4. There are multiple rollers 7, arranged sequentially along the length of the conveyor belt 1. As shown in Figures 3 and 6 , the air duct 2c is provided with several air holes 3, arranged sequentially along the length of the conveyor belt 1, with the openings of the air holes 3 facing upward. The plates of the support plate 2a on either side of the air duct 2c are tilted upward by 1°-3° from the inside out, typically by 2°. At the center of the support plate 2a is a trough 2b extending along the length of the conveyor belt 1. An air duct 2c is embedded within this trough, with air holes 3 located on its upper side. One end of the duct 2c is connected to a connecting pipe 10, which is connected to the blower. A plug is secured to the other end of the duct. Both the duct 2c and the trough 2b have rectangular or square cross-sections to prevent the air holes 3 from shifting in orientation.

[0038] As shown in Figure 4, two baffles 4 are symmetrically arranged on both sides of the conveyor belt 1, and two insect deflectors 5 are symmetrically arranged on both sides of the conveyor belt 1. The support plate 2a has a symmetrical structure. The middle part of each baffle 4 is fixed to the corresponding side edge of the support plate 2a, and the lower side edge of each baffle 4 is bent outward to form an outward curved strip. As shown in Figure 5, both side edges of the support plate 2a have an upwardly inclined inclined portion 2a1. The outer side of the inclined portion 2a1 is integrally connected to a fixed portion 2a2 fixed to the baffle 4. The fixed portion 2a2 is in an inverted L shape and has a stable structure. The fixed portion 2d and the baffle 4 can be welded or screwed. Each insect deflector 5 is separately arranged from the corresponding baffle 4 to form a ventilation gap 6. The insect deflector 5 is secured to the baffle 4 by screws. Several screws are arranged sequentially along the length of the conveyor belt 1 (not shown). To maintain a ventilation gap 6 between the baffles 4 and 5, spacers can be fixed between them. These spacers can also be fixed at each end of the baffle 4, or they can be fitted over the screws. The lower edge of each insect deflector 5 elastically rests against the upper belt 1a of the conveyor belt 1. Each upper edge of the insect deflector 5 has an inwardly protruding, downwardly sloping retaining rib 5a1. The inner edge of the retaining rib 5a1 has a downwardly protruding lip 5a2 that slopes outward from top to bottom. Each insect deflector 5 includes a sealing strip 5b made of rubber or silicone, and a main body 5a made of a rigid plastic or metal material, such as stainless steel or aluminum alloy. If the main body 5a is made of metal, it can be sprayed with anti-rust paint. The retaining rib 5a1 is integrally formed on the upper side of the main plate 5a, while the sealing strip 5b is integrally injection-molded on the lower side of the main plate 5a. The sealing strip 5b elastically rests against the upper surface of the upper belt section 1a of the conveyor belt 1. Each lower side of the main plate 5a has an inwardly protruding, downwardly sloping inward portion 5a3. The sealing strip 5b is secured to the inwardly sloping portion 5a3. The two sides of the upper belt section 1a of the conveyor belt 1 extend to face the corresponding inwardly sloping portion 5a3. When the blower is operating, the two sides of the upper belt section 1a of the conveyor belt 1 can rest against the inwardly sloping portion 5a3. The lower side of each sealing strip 5b is bent inward and overlaps the edge of the upper belt section 1a of the conveyor belt 1. Each baffle 4 has an inwardly protruding guide strip 4a located above the retaining rib 5a1. The inner side of each guide strip 4a is tilted downward.

[0039] Nutrients and insects are laid on the upper surface of the upper belt body 1a of the conveyor belt 1 to feed the insects. Because the insect-blocking plate 5 is located above the conveyor belt 1, and the lower side of the insect-blocking plate 5 elastically abuts against the upper belt body 1a of the conveyor belt 1, the insect-blocking plate 5 has a blocking effect on the insects and nutrients, preventing the insects from crawling out of the conveyor belt 1 or being blown away, reducing the loss of insects during the feeding process, and can reduce breeding costs and increase production. When the fan is working, pressurized air enters the air duct 2c, and then blows upward through the air hole 3. The air enters between the upper belt body 1a of the conveyor belt 1 and the support plate 2a, lifting the upper belt body 1a of the conveyor belt 1 and causing the upper belt body 1a of the conveyor belt 1 to float. After the upper belt body 1a of the conveyor belt 1 is suspended, air flows out from both sides of the support plate 2a and enters the ventilation gap 6 between the baffle 4 and the insect deflector 5. The air then flows upward and then turns into the gap between the retaining rib 5a1 and the guide bar 4a. When it flows out from between the retaining rib 5a1 and the guide bar 4a, the air is guided to be blown out at a downward angle due to the downward inclination of the inner side of the guide bar 4a and the retaining rib 5a1. The air is finally blown toward the nutrients and insects on the conveyor belt 1. After adopting the conveyor belt mechanism of the present insect breeding equipment, the air is not only used to suspend and support the upper belt body 1a of the conveyor belt 1, but also can be blown toward the upper surface of the conveyor belt 1 through the guidance of the baffle 4 and the insect deflector 5 to deliver fresh air to the insects and cool them down, thereby reducing losses in insect breeding, lowering breeding costs and increasing yields, thus achieving dual uses of air. The insect-blocking plate 5 with the retaining ribs 5a1 and the baffle 4 with the guide bars 4a not only prevent insects from crawling off the conveyor belt 1, but also guide air and block and reduce its pressure. This allows the air to be blown downward from between the retaining ribs 5a1 and the guide bars 4a in a reduced-pressure state without blowing insects away, thereby delivering fresh air and cooling the insects. The coordinated structure of the insect-blocking plate 5 and the baffle 4 also serves a dual purpose. Therefore, an insect-raising device employing this conveyor belt mechanism can reduce insect loss when raising insects on the air-suspended conveyor belt 1. Furthermore, the dual purpose of the air and the coordinated structure of the insect-blocking plate 5 and the baffle 4 can reduce costs and increase production.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
