Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a feeding mechanism. Background Technology

[0002] The existing green and environmentally friendly methods for treating kitchen waste mainly involve raising black soldier flies to degrade kitchen waste. This can quickly digest the perishable components in kitchen waste, effectively kill bacteria in the waste, and completely block the spread of homologous protein viruses in the food chain. At the same time, black soldier flies can also be used directly to feed poultry or made into high-protein feed. Traditional methods of raising black soldier flies involve manually digging trenches, placing kitchen waste in them, and then releasing the black soldier fly larvae for rearing and hatching. However, the kitchen waste produces an unpleasant odor that affects the lives of nearby residents, and it is also labor-intensive. To address this, automated black soldier fly farming is achieved by stacking feed trays within the breeding chamber, allowing for the batch processing of kitchen waste within the workshop. However, this requires placing kitchen waste and black soldier fly larvae in individual feed trays. While manually adding the larvae is not difficult, the high moisture content and weight of the kitchen waste make manual loading a heavy and laborious process, whether the kitchen waste is placed in a static or dynamic tray. Using mechanical units for loading and transportation requires consideration of the coordination between the overall mechanical equipment. Utility Model Content

[0003] In view of the problems existing in the prior art, the main purpose of this utility model is to provide a feeding mechanism that does not require manual intervention, uses a conveyor belt to transport the material tray, and uses limiting claws to limit the material tray. There is no need to cycle start and stop the conveyor belt during feeding, and the overall operation of the mechanism is smoother.

[0004] This utility model provides a feeding mechanism, including:

[0005] A conveyor belt for conveying a tray along its length, the tray having a bottom wall and a vertical wall protruding from the bottom wall;

[0006] A hopper, which is mounted on the conveyor belt, has a discharge port on the side facing the conveyor belt;

[0007] A limiting claw is provided on one side of the hopper outlet along the length direction of the conveyor belt; the limiting claw can rotate around a horizontal axis to be attached to / separated from the vertical wall of the material tray, thereby limiting / releasing the material tray in the length direction of the conveyor belt; when the material tray is limited by the limiting claw, the bottom wall of the material tray is opposite to the outlet.

[0008] As a further description of the above technical solution, the conveyor belt is provided with a detection unit, which is used to detect whether the material tray has reached the preset receiving position.

[0009] As a further description of the above technical solution, the detection unit includes a displacement sensor and a through-beam sensor; wherein,

[0010] The displacement sensor is located on one side of the conveyor belt;

[0011] The transmitting and receiving ends of the through-beam sensor are respectively located on both sides of the conveyor belt.

[0012] As a further description of the above technical solution, when the material tray reaches the preset receiving position, the claw end of the limiting claw abuts against the vertical wall of the material tray to limit the material tray in the length direction of the conveyor belt.

[0013] As a further description of the above technical solution, when the material tray reaches the preset receiving position, the discharge port of the hopper is opened for a preset duration.

[0014] As a further description of the above technical solution, the hopper adopts a spiral discharge method.

[0015] As a further description of the above technical solution, the conveyor belt is a roller conveyor belt.

[0016] As a further description of the above technical solution, it also includes a bracket, the support portion of which spans across the conveyor belt, and the hopper and the limiting claw are both mounted on the support portion of the bracket.

[0017] As a further description of the above technical solution, the distance between the support portion and the conveyor belt on the side facing the conveyor belt is not less than the height of the material tray.

[0018] The beneficial effects of this utility model are as follows:

[0019] In the feeding mechanism provided by this utility model, a conveyor belt transports material trays along its length, and a hopper is mounted on the conveyor belt with a discharge port on its side facing the conveyor belt. When the material tray is transported by the conveyor belt to the preset receiving position, the limiting claw rotates around the horizontal axis to abut against the vertical wall of the material tray, thereby limiting the material tray along the length of the conveyor belt. At this time, the bottom wall of the limited material tray is opposite to the discharge port of the hopper to receive the material, and the conveyor belt does not need to be turned off. The remaining material trays (including empty material trays and material trays already carrying material) can continue to be transported forward with the operation of the conveyor belt. After receiving a certain amount of material, the limiting claw rotates in the opposite direction around the horizontal axis to reset, thereby separating from the vertical wall of the material tray to release the material tray, which can then continue to be transported forward. Therefore, the feeding mechanism disclosed in this embodiment does not require manual intervention, uses a conveyor belt to transport material trays, and uses limiting claws to limit the material trays. There is no need to repeatedly start and stop the conveyor belt during feeding, and the overall operation of the mechanism is smoother. Attached Figure Description

[0028] Please see Figures 1 to 4 This embodiment provides a feeding mechanism, which includes:

[0029] Conveyor belt 1, the conveyor belt 1 is used to convey material tray 2 along its length direction, the material tray 2 is provided with a bottom wall 21 and a vertical wall 22 protruding from the bottom wall 21;

[0030] The hopper 3 is mounted on the conveyor belt 1 and has a discharge port 31 on the side facing the conveyor belt 1.

[0031] The limiting claw 4 is located on one side of the discharge port 31 of the hopper 3 along the length direction of the conveyor belt 1. The limiting claw 4 can rotate around a horizontal axis to be attached to / separated from the vertical wall 22 of the material tray 2, thereby limiting / releasing the material tray 2 along the length direction of the conveyor belt 1. When the material tray 2 is limited by the limiting claw 4, the bottom wall 21 of the material tray 2 is opposite to the discharge port 31.

[0032] With the above structure, the conveyor belt 1 transports the material tray 2 along its length, and the hopper 3 is mounted on the conveyor belt 1. It has a discharge port 31 on the side facing the conveyor belt 1. When the material tray 2 is transported by the conveyor belt 1 to the preset receiving position, the limiting claw 4 rotates around the horizontal axis to abut against the vertical wall 22 of the material tray 2, thereby limiting the material tray 2 in the length direction of the conveyor belt 1. At this time, the bottom wall 21 of the material tray 2 that can be limited is opposite to the discharge port 31 of the hopper 3 to receive the material, and the conveyor belt 1 does not need to be closed. The remaining material trays 2 (including empty material trays 2 and material trays 2 that have already carried material) can continue to be transported forward with the operation of the conveyor belt 1. After receiving a certain amount of material, the limiting claw 4 rotates in the opposite direction around the horizontal axis to reset, thereby separating from the vertical wall 22 of the material tray 2 to release the material tray 2, which can continue to be transported forward. Therefore, the feeding mechanism disclosed in this embodiment does not require manual intervention. It uses a conveyor belt 1 to transport the material tray 2 and a limiting claw 4 to limit the material tray 2. During the feeding process, there is no need to cycle start and stop the conveyor belt 1, and the overall operation of the mechanism is smoother.

[0033] Please see Figure 1 , Figure 3 as well as Figure 4 Specifically, in this embodiment, the conveyor belt 1 is defined as conveying the material trays 2 from right to left. The bottom wall 21 of the material tray 2 is rectangular, and it surrounds four vertical walls 22, so that the material tray 2 as a whole is rectangular frame-shaped. Multiple material trays 2 are loaded from the right end of the conveyor belt 1. After they are conveyed to the hopper 3 to receive a certain amount of material, they continue to be conveyed to the left until they reach the left end of the conveyor belt 1, so as to be transferred to the next work station.

[0034] Specifically, in this embodiment, the conveyor belt 1 is equipped with a detection unit, which is used to detect whether the material tray 2 has reached the preset receiving position. To ensure accurate detection of whether the traveling position of the material tray 2 has reached the preset receiving position, the detection unit includes a displacement sensor 51 and a through-beam sensor 52; wherein, the displacement sensor 51 is located on the front side of the conveyor belt 1, and the transmitting end and receiving end of the through-beam sensor 52 are respectively located on the front and rear sides of the conveyor belt 1, and the transmitting end of the displacement sensor 51 and the through-beam sensor 52 coincide in the front-rear direction of the conveyor belt 1. Of course, in other embodiments, the displacement sensor 51 can also be located on the rear side of the conveyor belt 1 and coincide with the receiving end of the through-beam sensor 52.

[0035] Please see Figures 1 to 4Specifically, in this embodiment, when the material tray 2 reaches the preset receiving position, the limiting claw 4 rotates around the horizontal axis so that its claw end 41 is in contact with the vertical wall 22 of the material tray 2, thereby limiting the material tray 2 in the length direction of the conveyor belt 1. At this time, the bottom wall 21 of the material tray 2 is opposite to the discharge port 31 of the hopper 3 to receive the material.

[0036] Specifically, in this embodiment, when the material tray 2 reaches the preset receiving position, the discharge port 31 of the hopper 3 is opened for a preset time, so that the material tray 2 can receive a preset amount of material before moving forward.

[0037] Specifically, in this embodiment, the hopper 3 adopts a spiral discharge method to ensure the uniformity of material discharge from the discharge port 31 into the material tray 2. This is because the material in this embodiment is kitchen waste with a large amount of moisture. Of course, in other embodiments, the hopper 3 may also adopt other discharge methods according to the characteristics of the material.

[0038] Please see Figure 1 Specifically, in this embodiment, the conveyor belt 1 is a roller-type conveyor belt 1, which has a simple structure.

[0039] Maintenance is convenient. When the material tray 2 is limited by the limiting claw 4, the roller group under the conveyor belt 1 still rotates around its own axis, so that there is dynamic friction between it and the material tray 2, which also reduces the wear on the conveyor belt 1.

[0040] Please continue reading. Figures 1 to 4 Specifically, in this embodiment, the feeding mechanism further includes a bracket 6, the support portion 61 of which spans across the conveyor belt 1, and the hopper 3 and the limiting claw 4 are both mounted on the support portion 61 of the bracket 6. More specifically, the distance between the support portion 61 and the conveyor belt 1 is not less than the height of the material tray 2, thereby ensuring the smooth conveying of the material tray 2.

[0041] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
