Description

Feed return mechanism of breeding equipment Technical Field

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

[0002] Currently, biological treatment technology uses breeding equipment to breed insects. The insects on the breeding equipment will eventually grow into mature insects of appropriate size by ingesting and digesting food raw materials. The insects and insect excrement harvested from the breeding equipment can be further processed to obtain high-quality organic fertilizer.

[0003] Breeding equipment usually has multiple layers of conveyor belts, and the insects grow gradually as they pass through each layer of conveyor belts in turn. During the breeding process, each layer of conveyor belt usually stays for a period of time, such as 24 hours, for the insects to feed, and then is transported to the next layer of conveyor belt to continue feeding. For example, a black soldier fly larvae breeding device disclosed in the patent document (application number: 202020173223.9) includes a discharging device and a multi-layer belt conveyor. Each layer of the belt conveyor is provided with a feed end and a discharge end. The upper and lower belt conveyors are staggered along the length direction, so that the discharge end of the upper belt conveyor is above the feed end of the lower belt conveyor.

[0004] The following deficiencies exist in the actual use of this device: Since the development of insects is affected by many factors, including temperature, humidity, feed quality, density, and breeding environment, in addition to the above factors, light, oxygen supply, etc. may also have an impact on the development speed of insects. Therefore, in the actual production and manufacturing process of this device, it is inevitable that the insects will not yet mature when they reach the bottom conveyor belt. At this time, since the material on the bottom conveyor belt can only flow to the discharge device, the breeding equipment has the disadvantages of a relatively single and fixed conveying flow direction and insufficient operational flexibility. At this time, if the immature insects directly enter the discharge device for the production of organic fertilizer, then since the immature insects are usually smaller in size and have lower nutritional value, they cannot reach the production level of mature insects. Therefore, problems such as reduced organic fertilizer production and insufficient nutrient content will occur.

[0005] To avoid these issues, the conventional solution is to precisely control feeding conditions such as temperature and humidity to ensure that the insects are mature by the time they reach the bottom conveyor belt. If the insects still remain immature at the bottom conveyor belt, the system increases the time they remain on the conveyor belt and re-feeds them with raw materials until they reach maturity before being discharged to the discharge device.

[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 material return mechanism for breeding equipment. The present invention solves the problems of the existing breeding equipment having a relatively single and fixed conveying flow direction and low operational flexibility.

[0008] The objectives of the present invention can be achieved through the following technical solutions: a return mechanism for breeding equipment, the breeding equipment includes an upper conveyor belt, a lower conveyor belt and a discharging device, the end of the lower conveyor belt is located above the discharging device, and is characterized in that the return mechanism includes a conveyor belt assembly, an elevator and a horizontally arranged guide rail, the conveyor belt assembly is slidably connected to the guide rail, the conveyor belt assembly can be translated to between the end of the lower conveyor belt and the discharging device and make the end of the conveyor belt assembly above the feed end of the elevator, and the discharging end of the elevator is located above the upper conveyor belt.

[0009] In this return mechanism, a horizontal guide rail is provided, along which a conveyor belt assembly is slidably connected, allowing the conveyor belt assembly to move horizontally. During operation, if the insects on the lower conveyor belt have matured, the end of the lower conveyor belt is positioned above the discharge device, allowing the material discharged from the lower conveyor belt to fall directly onto the discharge device and then flow to the next processing station. If the insects on the lower conveyor belt are not yet mature, the conveyor belt assembly can be slid along the guide rail between the end of the lower conveyor belt and the discharge device, with the end of the conveyor belt assembly positioned above the feed end of the elevator. This allows the conveyor belt assembly to connect the return material, and the material on the lower conveyor belt can then pass through the conveyor belt assembly and the elevator and return to the upper conveyor belt, where it can continue to be cultivated on the upper conveyor belt for a period of time, such as 24 hours. The lower conveyor belt can then normally receive new insects for cultivation and discharge. Of course, it can also be left undisturbed until the insects on the upper conveyor belt are fully cultivated and then transferred to the lower conveyor belt, thus providing strong operational flexibility.

[0010] The return mechanism of the breeding equipment is achieved by adding an elevator and a movable conveyor belt component to the traditional breeding equipment. The conveyor belt component is cleverly designed to switch to different functional modes, so that the discharge position of the breeding equipment has two conveying flow directions: discharge and return. The conveying flow direction is no longer single and fixed. In this way, the conveying flow direction can be flexibly adjusted according to the development of the insects on the lower conveyor belt, making the breeding equipment highly flexible in operation, easy to use, and highly practical.

[0011] In the return mechanism of the above-mentioned breeding equipment, the conveyor belt assembly is arranged below the lower conveyor belt, and the guide rail and the conveyor belt assembly are arranged parallel to the lower conveyor belt. The conveyor belt assembly can extend outward from below the end of the lower conveyor belt. After the conveyor belt assembly extends outward, it is located between the end of the lower conveyor belt and the discharge device, and the end of the conveyor belt assembly is located above the feed end of the elevator.

[0012] In the initial reset state, the conveyor belt assembly is located below the lower conveyor belt, so that the conveyor belt assembly avoids the unloading space between the end of the lower conveyor belt and the discharge device, and therefore does not prevent the material on the lower conveyor belt from falling onto the discharge device. When the conveyor belt assembly extends outward from below the end of the lower conveyor belt, the conveyor belt assembly is located between the end of the lower conveyor belt and the discharge device. At this time, the conveyor belt assembly switches to the connecting and returning state, so that the material on the lower conveyor belt can pass through the conveyor belt assembly and the elevator in turn and return to the upper conveyor belt. In this design, the conveyor belt assembly can be telescopically arranged below the lower conveyor belt. This structure effectively utilizes the space below the lower conveyor belt, and allows the conveyor belt assembly to quickly switch between the initial reset state and the connecting and returning state by moving a small stroke. Therefore, the equipment has the advantages of compact structure, high operating efficiency, and good stability.

[0013] In the above-mentioned return mechanism of the breeding equipment, the return mechanism also includes a mounting bracket, the lower conveyor belt is rotatably set on the mounting bracket, the guide rail is fixedly connected to the mounting bracket, and the conveyor belt assembly includes a docking bracket and a docking conveyor belt rotatably set on the docking bracket, and the docking bracket is slidably connected to the guide rail on the mounting bracket. The docking bracket is slidably connected to the guide rail on the mounting bracket, so that the conveyor belt assembly has high movement stability, thereby ensuring that it can switch positions stably and smoothly. The guide rail is set on the mounting bracket, so that the return mechanism does not need to set up other additional components for installing the guide rail, thereby achieving the purpose of simplifying the structure. Moreover, this design makes the conveyor belt assembly and the lower conveyor belt form a whole. When the placement position of the lower conveyor belt is changed due to space requirements, the relative position of the conveyor belt assembly and the lower conveyor belt does not need to be adjusted additionally, which makes the return mechanism have the advantages of being easy to use and highly practical.

[0014] In the above-mentioned return mechanism of the breeding equipment, the docking bracket includes two oppositely arranged side panels 1, the mounting bracket includes two oppositely arranged side panels 2, the guide rails are two, and the two guide rails are respectively fixed on the outer walls of the two side panels 2. The upper ends of the two connecting plates are respectively slidably connected to the two guide rails through sliders, and the lower ends of the two connecting plates are respectively fixed to the two side panels 1. The docking bracket is connected to the two guide rails through the two connecting plates, so that the left and right side panels 1 of the docking bracket are supported and positioned, thereby providing better stability and balance for the docking bracket, avoiding vibration and shaking caused by deflection or imbalance of the docking bracket, and improving the operational stability of the equipment. At the same time, this design can also evenly distribute the weight and load of the docking bracket to the two guide rails, reducing the load on the single-side guide rail, thereby increasing the life and reliability of the guide rail.

[0015] In the aforementioned return mechanism of the breeding equipment, the discharge end of the elevator is located above the head end of the upper conveyor belt. A feeding component is provided above the upper conveyor belt, adjacent to the discharge end of the elevator. The feeding component can be a feed box with a discharge port at the bottom, or a feeding pipe, a feeding nozzle, etc. The feeding component is used to drop nutrients. When the elevator carries immature insects to the upper conveyor belt, the feeding component simultaneously drops nutrients as the upper conveyor belt rotates. In this way, the insects and nutrients can be evenly spread across the upper conveyor belt as the upper conveyor belt rotates, making operation very convenient. In traditional multi-layer conveyor lines, when the insects on the lower conveyor belt have not yet matured but the nutrients on the conveyor belt have been eaten by the insects, the lower conveyor belt cannot return the material and needs to remain stationary until the insects mature before being transported to the discharging device. Therefore, it is impossible to use the movement of the lower conveyor belt to add materials, and materials can only be added manually or by moving the feeding parts to make the lower conveyor belt full of nutrients. This will lead to problems such as troublesome feeding and high equipment costs.

[0016] In the material return mechanism of the above-mentioned breeding equipment, after the conveyor belt assembly extends outward from below the end of the lower conveyor belt, the end of the lower conveyor belt is located above the middle of the conveyor belt assembly. A material baffle is also provided on the upper side of the head end of the conveyor belt assembly, and the lower edge of the material baffle is in contact with the upper surface of the connecting conveyor belt. The lower edge of the material baffle is in contact with the upper surface of the connecting conveyor belt, so that the material baffle has the function of preventing materials from falling. The end of the lower conveyor belt is located above the middle of the conveyor belt assembly, so that the conveyor belt assembly can better receive the materials dropped from the lower conveyor belt. At the same time, with the function of the material baffle, it can better prevent the materials from falling out from the head end of the conveyor belt assembly, ensuring that all the materials dropped from the lower conveyor belt can be transported to the elevator through the conveyor belt assembly.

[0017] In the aforementioned feed return mechanism of the farming equipment, the top edge of side panel 1 is higher than the upper surface of the connecting conveyor belt, and the two sides of the connecting conveyor belt are respectively aligned with the inner sidewalls of the two side panels 1. This design enables side panel 1 to function as a material retaining device, ensuring that all material falling from the lower conveyor belt is transported to the elevator through the conveyor belt assembly.

[0018] In the above-mentioned return mechanism of the breeding equipment, the return mechanism also includes a reinforcing plate and a horizontally arranged cylinder. The reinforcing plate is located on the lower side of the conveyor belt assembly, and the two ends of the reinforcing plate are respectively fixedly connected to the lower ends of the two connecting plates. The cylinder bracket is provided with a horizontally arranged cylinder. The length direction of the piston rod of the cylinder is parallel to the length direction of the conveyor belt assembly, and the extended end of the cylinder piston rod is fixedly connected to the reinforcing plate. The two ends of the reinforcing plate are respectively fixedly connected to the lower ends of the two connecting plates, so that the two connecting plates and the reinforcing plate together form a relatively stable structure, thereby improving the installation stability of the conveyor belt assembly. Since the piston rod of the cylinder is fixedly connected to the reinforcing plate, the reinforcing plate also plays the role of connecting the cylinder, so that the cylinder can push the conveyor belt assembly back and forth. The piston rod of the cylinder can be maintained in a state of extending outward or retracting inward, so that the conveyor belt assembly can be maintained in the initial reset state and the connecting return state, respectively, so that the equipment has the advantages of high automation and stable operation.

[0019] In the aforementioned return mechanism of the farming equipment, the return mechanism further includes a locking pin disposed on the connecting plate, and a locking hole is defined in the second side plate. When the conveyor belt assembly extends outward to a position between the end of the lower conveyor belt and the discharge device, the locking pin can be inserted into the locking hole. This method manually operates the conveyor belt assembly to translate back and forth. When the return material needs to be connected, the conveyor belt assembly is simply manually pushed outward until the locking pin is aligned with the locking hole. At this point, the locking pin can be inserted into the locking hole, preventing the conveyor belt assembly from automatically retracting inward, thereby ensuring that the conveyor belt assembly can stably transport the material output from the lower conveyor belt to the elevator.

[0020] In the aforementioned return mechanism of the farming equipment, the discharge device is a horizontally arranged discharge conveyor belt, the length of which is perpendicular to the length of the conveyor belt assembly. The elevator is located on the side of the discharge device facing away from the lower conveyor belt. This design facilitates the arrangement of the discharge conveyor belt and elevator, allowing the elevator to be closer to the lower conveyor belt. This shortens the length and weight of the conveyor belt assembly, and allows the conveyor belt assembly to quickly switch between the initial reset state and the feed return state with only a small travel distance. Consequently, the equipment has the advantages of a compact structure, high operating efficiency, and good stability.

[0021] Compared with the existing technology, the return mechanism of this breeding equipment has the following advantages:

[0022] 1. The return mechanism of this breeding equipment is achieved by adding a hoist and a movable conveyor belt assembly to the traditional breeding equipment. The conveyor belt assembly is cleverly designed to switch to different functional modes, so that the discharge position of the breeding equipment has two conveying flow directions: discharge and return. The conveying flow direction is no longer single and fixed. In this way, the conveying flow direction can be flexibly adjusted according to the development of the insects on the lower conveyor belt, making the breeding equipment highly flexible in operation, easy to use, and highly practical.

[0023] 2. This return mechanism is equipped with a feeding component above the upper conveyor belt, which is close to the discharge end of the elevator. When the elevator carries immature insects to the upper conveyor belt, as the upper conveyor belt rotates, the feeding component also simultaneously puts nutrients. In this way, the insects and nutrients can be evenly spread on the upper conveyor belt by utilizing the rotation of the upper conveyor belt, which is very convenient to operate.

[0024] 3. This return mechanism also has the advantages of compact structure, high operating efficiency and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

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 Figures 1 and 2, the breeding equipment includes an upper conveyor belt 1, a lower conveyor belt 2 and a discharge device 3. The end of the lower conveyor belt 2 is located above the discharge device 3. The lower conveyor belt 2 and the upper conveyor belt 1 are staggered. The lower conveyor belt 2 and the upper conveyor belt 1 run in opposite directions. The end of the lower conveyor belt 2 is retracted inward relative to the head end of the upper conveyor belt 1, while the head end of the lower conveyor belt 2 protrudes outward relative to the end of the upper conveyor belt 1. In this way, the material output from the end of the upper conveyor belt 1 can fall onto the lower conveyor belt 2. A feeding component 9 is provided above the upper conveyor belt 1, adjacent to the discharge end 52 of the elevator 5. The feeding component 9 is used to feed nutrients. In this embodiment, the feeding component 9 is a material box with a discharge port at the bottom. Of course, the feeding component 9 can also be a feeding pipe, a feeding nozzle, etc.

[0036] As shown in Figures 1 and 2, the return mechanism includes a conveyor belt assembly 4, an elevator 5, and a horizontally arranged guide rail 6. The conveyor belt assembly 4 is slidably connected to the guide rail 6. As shown in Figures 3 and 4, the conveyor belt assembly 4 is arranged below the lower conveyor belt 2. The guide rail 6 and the conveyor belt assembly 4 are both arranged parallel to the lower conveyor belt 2. The conveyor belt assembly 4 can extend outward from below the end of the lower conveyor belt 2. After the conveyor belt assembly 4 extends outward, it is located between the end of the lower conveyor belt 2 and the discharge device 3, and the end of the conveyor belt assembly 4 is located above the feed end 51 of the elevator 5. The discharge end 52 of the elevator 5 is located above the head end of the upper conveyor belt 1. The discharge device 3 is a horizontally arranged discharge conveyor belt. The length direction of the discharge device 3 is perpendicular to the length direction of the conveyor belt assembly 4. The elevator 5 is arranged on the side of the discharge device 3 facing away from the lower conveyor belt 2. The hoist 5 is a prior art and can be purchased directly on the market. For example, the patent document with application number 201720445685.X discloses a C-type hoist.

[0037] As shown in Figures 3 to 5, the return mechanism also includes a mounting bracket 7, on which the lower conveyor belt 2 is rotatably mounted, and a guide rail 6 is fixedly connected to the mounting bracket 7. The conveyor belt assembly 4 includes a connecting bracket 41 and a connecting conveyor belt 42 rotatably mounted on the connecting bracket 41. The connecting bracket 41 is slidably connected to the guide rail 6 on the mounting bracket 7. Specifically, the connecting bracket 41 includes two oppositely disposed side panels 1 411, and the mounting bracket 7 includes two oppositely disposed side panels 2 71. There are two guide rails 6, each of which is fixedly connected to the outer side walls of the two side panels 2 71. The upper ends of the two connecting plates 8 are slidably connected to the two guide rails 6 via sliders 15, and the lower ends of the two connecting plates 8 are fixedly connected to the two side panels 1 411. The sliders 15 are fixed to the connecting plates 8 and sleeved on the guide rails 6. This design supports and positions both the left and right side panels 411 of the docking bracket 41, thereby providing better stability and balance for the docking bracket 41, avoiding vibration and shaking caused by deflection or imbalance of the docking bracket 41, and improving the operational stability of the equipment.

[0038] As shown in Figures 4 and 5, when the conveyor belt assembly 4 extends outward from below the end of the lower conveyor belt 2, the end of the lower conveyor belt 2 is located above the middle of the conveyor belt assembly 4. A material blocking plate 10 is further provided on the upper side of the head end of the conveyor belt assembly 4. The lower edge of the material blocking plate 10 is in contact with the upper surface of the connecting conveyor belt 42. The top edge of the side plate 1 411 is higher than the upper surface of the connecting conveyor belt 42. The two side edges of the connecting conveyor belt 42 are respectively in contact with the inner side walls of the two side plates 1 411. The lower edge of the material blocking plate 10 is in contact with the upper surface of the connecting conveyor belt 42, so that the material blocking plate 10 has the function of preventing materials from falling. The end of the lower conveyor belt 2 is located above the middle of the conveyor belt assembly 4, so that the conveyor belt assembly 4 can better receive the material falling from the lower conveyor belt 2. At the same time, with the function of the material blocking plate 10, it can better prevent the material from falling out from the head end of the conveyor belt assembly 4, and ensure that all the materials falling from the lower conveyor belt 2 can be transported to the elevator 5 through the conveyor belt assembly 4.

[0039] As shown in Figures 4 and 6, the return mechanism also includes a reinforcing plate 11 and a horizontally arranged cylinder 12. The cylinder 12 is fixedly connected to the mounting bracket 7 through a fixing frame. The mounting bracket 7 is not shown in the figure. Alternatively, a support platform specifically for mounting the cylinder 12 can be fixed on the ground to achieve the installation of the cylinder 12. The reinforcing plate 11 is located on the lower side of the conveyor belt assembly 4. The two ends of the reinforcing plate 11 are respectively fixedly connected to the lower ends of the two connecting plates 8. The length direction of the piston rod of the cylinder 12 is parallel to the length direction of the conveyor belt assembly 4, and the protruding end of the piston rod of the cylinder 12 is fixedly connected to the reinforcing plate 11. The piston rod of the cylinder 12 can be maintained in a state of extending outward or retracting inward, so that the conveyor belt assembly 4 can be maintained in the initial reset state and the connecting return state, so that the equipment has the advantages of high automation and stable operation.

[0040] The upper conveyor belt 1 and the lower conveyor belt 2 can rotate in both directions, but usually, the materials are conveyed along the directions indicated by the straight arrows in Figures 2 and 4.

[0041] The following describes the working principle of this device in conjunction with the accompanying drawings:

[0042] During operation, the conveyor belt assembly 4 is typically in its initial reset state, as shown in Figures 1 and 2. If the insects on the lower conveyor belt 2 have matured, the end of the lower conveyor belt 2 is positioned above the discharge device 3, allowing the material discharged from the lower conveyor belt 2 to fall directly onto the discharge device 3 and flow to the next processing station.

[0043] As shown in Figures 3 and 4, if the insects on the lower conveyor belt 2 have not yet matured, the cylinder 12 drives the conveyor belt assembly 4 to slide along the guide rail 6 between the end of the lower conveyor belt 2 and the discharge device 3, and the end of the conveyor belt assembly 4 is positioned above the feed end 51 of the elevator 5. In this way, the conveyor belt assembly 4 has the function of connecting and returning the material on the lower conveyor belt 2. The material can then pass through the conveyor belt assembly 4 and the elevator 5 and return to the upper conveyor belt 1. When the elevator 5 carries the immature insects to the upper conveyor belt 1, as the upper conveyor belt 1 rotates, the feeding component 9 also synchronously releases nutrients. In this way, the rotation of the upper conveyor belt 1 can be used to evenly spread the insects and nutrients over the upper conveyor belt 1. The insects continue to be cultivated on the upper conveyor belt 1 for a period of time, such as 24 hours, and then are transported to the lower conveyor belt 2 to be cultivated to maturity. Afterwards, as shown in FIG1 and FIG2, the lower conveyor belt 2 conveys the insects and their excrement to the discharging device 3, and then flows to the next processing station.

[0044] Example 2

[0045] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: as shown in FIG7 , the return mechanism further includes a locking pin 13 provided on the connecting plate 8, and a locking hole 14 is provided on the second side plate 71. When the conveyor belt assembly 4 is extended outward to the position between the end of the lower conveyor belt 2 and the discharge device 3, the locking pin 13 can be inserted into the locking hole 14. This method is to manually operate the conveyor belt assembly 4 to move back and forth. When it is necessary to connect the return material, the conveyor belt assembly 4 only needs to be manually pushed outward until the locking pin 13 is aligned with the locking hole 14. At this time, the locking pin 13 can be inserted into the locking hole 14, so that the conveyor belt assembly 4 will not automatically retract inward, ensuring that the conveyor belt assembly 4 can stably transport the material output from the lower conveyor belt 2 to the elevator 5.
