Description

Feeding device for insect breeding equipment Technical Field

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

[0002] As human society's demand for protein energy continues to increase, finding new sources of protein to meet human needs is one of the current global issues. Insects have been increasingly valued as a new source of protein in recent years, especially the development and utilization of houseflies.

[0003] Houseflies, belonging to the Insecta, Diptera, Cyclosporidae, and Muscicapidae families, are excellent animal protein feeds. They boast strong reproductive capacity, a short life cycle, ease of intensive production, and abundant feed sources, earning them international recognition as a leading new protein resource. Currently, houseflies are typically farmed on a large scale in my country using a single set of insectary aquaculture equipment. During the breeding process, after eggs are deposited on the conveyor belt, feed must be replenished periodically. During this period, the conveyor belt cannot be moved, requiring feed replenishment via a feeding device installed above the conveyor belt.

[0004] At present, in the existing technology, the feeding device or the feeding device generally includes a conveying pipe arranged above the breeding conveyor belt, and the conveying pipe has several feeding ports, and the feeding ports are provided with valves. The valves control the opening and closing of the feeding ports through solenoid valves. For example, the first spiral conveying device disclosed in the Chinese patent document CN 107853249 B is a feeding device similar to this. When feeding is needed, the solenoid valve can be opened to open the valve to open the feeding port for feeding. However, after the above-mentioned feeding port is used for a long time, due to the certain viscosity of the feed and direct contact with the valve components related to the solenoid valve, it is easy to cause the valve at the feeding port to malfunction. At the same time, it is also easy to cause the feeding port to be blocked. The above factors will seriously affect the reliability of the feeding device.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a feeding device for insect breeding equipment. The technical problem to be solved by the present invention is how to improve the reliability of the feeding device.

[0007] The objectives of the present invention can be achieved through the following technical solutions: a feeding device for insect breeding equipment, the insect breeding system includes a breeding conveyor belt and a conveying main pipe for conveying feed, characterized in that the feeding device includes a feeding inner pipe and a feeding outer pipe arranged above the breeding conveyor belt and laid along the length direction of the breeding conveyor belt, the feeding inner pipe is connected to the conveying main pipe, the feeding outer pipe is sleeved on the outside of the feeding inner pipe and the two can rotate relative to each other, a plurality of feeding inner holes distributed along the same axial line are provided on the outer peripheral surface of the feeding inner pipe, a plurality of feeding outer holes corresponding to the feeding inner holes are provided on the outer peripheral surface of the feeding outer pipe, each feeding outer hole can be synchronously aligned or staggered with the corresponding feeding inner hole; when the feeding outer hole and the feeding inner hole are aligned, the feeding outer hole faces the upper surface of the breeding conveyor belt.

[0008] This feeding device is used in insect breeding equipment and is designed based on the characteristics of insect breeding feed. Different from the existing technology, the feeding device of the present invention not only cancels the structural design of opening and closing by setting solenoid valves and other valves at the traditional feeding port, but completely changes the existing traditional feeding device structure. Specifically, the feeding device in the present invention is mainly composed of a feeding inner tube and a feeding outer tube, both of which are laid above the breeding conveyor belt along the length direction of the breeding conveyor belt, and the feeding outer tube is sleeved on the outside of the feeding inner tube, and the two can rotate relative to each other. On this basis, a number of feeding inner holes distributed along the same axial line are opened on the outer peripheral surface of the feeding inner tube, and a number of feeding outer holes corresponding to the feeding inner holes are opened on the outer peripheral surface of the feeding outer tube. Through the above design, when the feeding inner tube and the feeding outer tube rotate relative to each other by a certain angle, for example, when the feeding outer tube rotates relative to the feeding inner tube by a certain angle, then all the feeding outer holes can rotate synchronously together until the feeding is completed. The outer feeding hole is aligned with the inner feeding hole. After calculation, it is found that the outer feeding hole is facing downward, that is, toward the upper surface of the breeding conveyor belt. Then, the feed in the inner feeding tube can flow out from the inner feeding tube to the breeding conveyor belt, thereby completing the opening and feeding of the feeding device. Moreover, since all the outer feeding holes are opened synchronously, the uniformity requirement of the feeding on the breeding conveyor belt of the insect breeding equipment can be met. After the feeding is completed, when the outer feeding tube is rotated a certain angle, each outer feeding hole can be synchronously staggered with the corresponding inner feeding hole until it is closed, thereby completing the closing of the feeding device. There will be no situation where some outer feeding holes are open and some are closed, and it is reliable to use. That is to say, through the design of the above-mentioned feeding inner tube and feeding outer tube, and the layout design of the corresponding feeding inner hole and feeding outer hole, the opening and closing action of this device is very simple and reliable. Only by making the feeding inner tube and feeding outer tube rotate relative to each other, the feeding requirements of the insect breeding equipment can be achieved; and through the opening and closing action of the above-mentioned feeding device, it can be seen that the opening and closing of the feeding place of this feeding device completely adopts a purely mechanical structure. A total of two tubular components, the feeding inner tube and the feeding outer tube, are involved. The structure is simple and reliable. This relative rotation of the entire tube is not affected by the viscosity of the feed, effectively avoiding the problem that the opening and closing structure of the valve at the existing feeding place is easily affected by the feed and malfunctions. At the same time, the feeding inner hole and the feeding outer hole are accompanied by relative rotation during the opening and closing process, which can play a role in shearing and stirring the nearby feed to a certain extent, so that the feeding inner hole and the feeding outer hole are not easy to be blocked when they are aligned. Therefore, through the above-mentioned new feeding device design, the reliability of the feeding device is effectively improved.

[0009] In the feeding device of the aforementioned insect farming equipment, a rotational gap is defined between the outer circumference of the inner feeding tube and the inner circumference of the outer feeding tube. A sealing structure is provided within the rotational gap to prevent feed in the inner feeding tube from flowing out of the inner feeding tube via the rotational gap. The coordinated design of the rotational gap and the sealing structure allows, on the one hand, the rotational gap to allow the inner and outer feeding tubes to rotate smoothly and avoid jamming, thereby ensuring the reliability of the feeding device. On the other hand, the sealing structure ensures that feed does not flow out of the inner feeding tube via the rotational gap, thereby preventing feed leakage and further improving the reliability of the device.

[0010] In the aforementioned feeding device for insect farming equipment, the sealing structure comprises several annular grooves surrounding the outer circumference of the inner feeding tube. These grooves are located on both sides of each inner feeding hole, and each groove houses a sealing ring. This sealing structure, comprised of the annular grooves and sealing rings, prevents relative rotation between the inner and outer feeding tubes while ensuring a sealed rotational gap, further enhancing the reliability of the device.

[0011] In the feeding device of the above-mentioned insect breeding equipment, the feeding outer tube is fixed, the feeding outer hole faces the upper surface of the breeding conveyor belt, the feeding inner tube is rotatable relative to the feeding outer tube, one end of the feeding inner tube is connected to the main feeding pipe by a hose, and the two ends of the hose are respectively sealed and fixed to the feeding inner tube and the main feeding pipe, while the other end of the feeding inner tube is sealed. The above-mentioned design adopts a combination of the feeding outer tube being fixed and the feeding inner tube being rotatable. Since the feed is stored in the feeding inner tube, and the feeding inner tube is connected to the main feeding pipe, when the feeding inner tube rotates, it is easy to cause sealing problems at the connection between the feeding inner tube and the main feeding pipe. To overcome this sealing problem, one end of the feeding inner tube is connected to the main feeding pipe by a hose, and the other end is sealed. Since the hose can be twisted and deformed, the two ends of the hose are sealed and fixed to the feeding inner tube and the main feeding pipe without affecting the rotation, thereby preventing leakage at the connection between the feeding inner tube and the main feeding pipe, thereby further improving the reliability of the device.

[0012] In the aforementioned feeding device for insect farming equipment, the inner feeding hole and the outer feeding hole have the same diameter. This design reduces the rotation angle of the inner and outer feeding tubes, which controls the opening and closing of the feeding tubes. The less rotation, the more stable the feeding tubes are, thus further improving the reliability of the device.

[0013] In the feeding device of the above-mentioned insect breeding equipment, the main conveying pipe includes a main pipe arranged along the length of the breeding conveyor belt and a plurality of branch pipes arranged at intervals along the width of the breeding conveyor belt and connected to the main pipe, and each branch pipe is connected to at least one feeding inner pipe. In insect breeding equipment, the breeding conveyor belt is generally relatively long. Therefore, through the above pipeline layout design, the design length of each feeding inner pipe can be shortened. From an overall perspective, there are multiple sections of relatively short feeding inner pipes distributed above the breeding conveyor belt. The shorter the feeding inner pipe, the better the rotation stability, and the easier it is to control its or the feeding outer pipe's rotation, which is conducive to further improving the reliability of the device. At the same time, the above multi-section feeding inner pipe design is also conducive to improving the convenience of transferring and transporting the device.

[0014] In the aforementioned feeding device for insect farming equipment, a rotating arm is fixed to the inner feeding tube. Driven by a driver, this rotating arm can reciprocate the inner feeding tube. This design allows the inner feeding tube to rotate automatically under the driver's control. Furthermore, the driver is externally mounted and prevents contact with the feed, thus preventing the driver from malfunctioning due to the feed, thereby improving the reliability of the device. The driver can be a pneumatic cylinder, an oil cylinder, a motor, or the like.

[0015] As an alternative, in the aforementioned feeding device for insect farming equipment, the inner feeding tube is fixed, while the outer feeding tube is rotatable relative to the inner feeding tube, with the inner feeding hole facing the upper surface of the farming conveyor belt. In this embodiment, the outer feeding tube is movable while the inner feeding tube is fixed, thus avoiding sealing issues at the connection between the inner feeding tube and the main feeding pipe caused by the rotation of the inner feeding tube, thereby improving the reliability of the device.

[0016] As an alternative, in the aforementioned feeding device of the insect farming apparatus, the sealing structure comprises a plurality of concentric annular grooves corresponding one to one with the inner holes of the feeder. These concentric annular grooves are formed on the outer circumference of the feeding inner tube and are concentric with the inner hole of the feeder. Rubber rings are positioned within these concentric annular grooves. This design also ensures the sealing of the rotational gap, improving the reliability of the apparatus.

[0017] In the above-mentioned feeding device of the insect breeding equipment, the insect breeding equipment includes a feed storage tank, which is connected to the main feeding pipe and is fed by a feeding pump. Through the above design, the feeding device can feed stably and reliably.

[0018] Compared with the existing technology, the feeding device of the insect breeding equipment has the following advantages: the structural design of the feeding device is reasonable, simple and ingenious, and the structural design of the traditional feeding port that is opened and closed by setting valves such as solenoid valves is eliminated, thereby avoiding problems such as component failure and blockage that are prone to occur here. At the same time, through innovative design, the feeding device can be opened and closed only by the mutual rotation of the feeding inner tube and the feeding outer tube. In addition, the feeding device is very stable and reliable to use, and the manufacturing cost is also low. BRIEF DESCRIPTION OF THE DRAWINGS
