Description

Technical Field

[0001] The present invention relates to the technical field of feed processing equipment, and in particular to a transmission device for pig feed production. Background Art

[0002] Pig feed is a mixture specifically designed to meet the nutritional needs of pigs at different growth stages. It provides key nutrients such as energy, protein, vitamins, and minerals required for pig growth and development. High-quality pig feed not only promotes healthy growth but also improves feed conversion efficiency, thereby enhancing breeding efficiency.

[0003] Pig feed is typically made from a variety of ingredients. These ingredients primarily include grains such as corn, wheat, and barley, which provide the primary energy source; plant-based protein sources such as soybean meal, cottonseed meal, and rapeseed meal, which are crucial for supporting muscle development in pigs; and animal-based protein sources such as fish meal or meat and bone meal. Animal protein sources such as fish meal and meat and bone meal are also common ingredients, especially in high-protein feed formulations. Furthermore, to ensure pigs receive a comprehensive and balanced diet, appropriate amounts of vitamins, minerals, amino acids, and enzymes are added to the feed. These ingredients work together to promote optimal growth performance and health.

[0004] Grains such as corn, wheat and barley are small in size and easily spilled during transportation due to shaking and bumping. Therefore, in order to facilitate transportation and handling, woven bags are used to pack corn, wheat and barley. However, after these raw materials are transported to the feed processing plant, they need to be packaged according to type for the convenience of feed processing. However, the raw materials packaged in woven bags need to be manually transported to the packaging location, and then the woven bags need to be cut open with a knife and the raw materials are poured into a storage container. This method not only consumes a lot of manpower, but is also slow and inefficient. Summary of the Invention

[0005] The present invention aims to provide a transmission device for pig feed production to solve the problems of slow speed and low efficiency in packaging pig feed raw materials.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a transmission device for pig feed production, comprising a conveyor belt, a material distribution mechanism, and an identification module; the conveyor belt is evenly distributed with a plurality of beveled teeth, the beveled direction of which is opposite to the conveying direction of the conveyor belt; a slitting knife is fixedly connected to a bracket of the conveyor belt, and the slitting knife is used to cut and open the surface of a woven bag containing feed on the conveyor belt;

[0007] The material distribution mechanism includes a support frame, a receiving hopper is fixedly connected to the support frame, the receiving hopper is located just below the discharge end of the conveyor belt, the bottom of the receiving hopper is laterally slidably connected to a distribution plate, the distribution plate is driven to move by a cylinder, a plurality of receiving holes are provided on the distribution plate, and the plurality of receiving ports are used to communicate with the receiving hopper, the aperture of the receiving hole is the same as the aperture of the discharge port of the receiving hopper, each of the receiving holes is connected to a material guide pipe, and a storage bin is provided at one end of the material guide pipe away from the material receiving hole; each storage bin is used to store a raw material for pig feed;

[0008] The recognition module is fixedly mounted on the opening knife. The recognition module includes a controller and a camera. The camera is electrically connected to the controller. The lens of the camera faces the conveyor belt. The camera is used to collect images of the packaging bags of raw materials. The controller is also electrically connected to the cylinder. The controller pre-records images of packaging bags of different raw materials. The controller is used to compare the image data transmitted by the camera with the graphics of the raw material packaging bags, and then control the cylinder to start and push the material dividing plate to move according to the comparison results, so that the material receiving hole is aligned with the discharge port of the receiving hopper.

[0009] The invention works as follows: When a woven bag filled with pig feed ingredients is placed on a conveyor belt, the belt's angled teeth, facing in the opposite direction of conveyance, penetrate the bag, preventing it from slipping and ensuring stable conveyance. As the bag moves along the conveyor belt to the opening blade, the blade cuts the bag's surface, opening it. The opened bag then continues to the conveyor belt's discharge end, where the ingredients fall into a hopper directly below. The bag is penetrated by the angled teeth, which, with their tips facing upward, hook the bag, preventing it from falling into the hopper. When the woven bag moves to the opening knife, the camera in the recognition module fixed on the opening knife collects the image of the woven bag facing the conveyor belt and transmits the image data to the controller. The controller compares the received image with the pre-recorded images of different raw material packaging bags, determines the type of raw material based on the comparison results, and then immediately controls the cylinder to start. The cylinder drives the dividing plate to move horizontally at the bottom of the hopper, so that the receiving holes corresponding to the type of raw material on the dividing plate are aligned with the discharge port of the hopper. At this time, the raw material enters the connected material guide pipe through the receiving hole and finally falls into the corresponding storage bin, thereby realizing automatic packaging of different raw materials.

[0010] Beneficial effects of the present invention:

[0011] 1. During the use of this solution, workers only need to place the woven bags containing feed raw materials directly on the conveyor belt, and it can automatically open the bag and identify the type of raw materials. Then, according to the type of raw materials, the receiving holes corresponding to the raw material types on the dividing plate are aligned with the discharge port of the receiving hopper. The raw materials enter the guide pipe connected to the receiving holes and finally fall into the corresponding storage bin. The entire packaging process relies on the transmission speed of the conveyor belt, without excessive human intervention, which greatly improves the packaging efficiency of the feed raw materials.

[0012] 2. This solution uses a camera to collect images and compares them through a controller. The controller then controls the cylinder to drive the distribution plate to move so that the receiving holes corresponding to the raw material types on the distribution plate are aligned with the discharge port of the receiving hopper, thus realizing automatic classification of different feed raw materials.

[0013] Furthermore, the blade of the opening knife is tilted, and the tilt direction of the blade is opposite to the conveying direction of the conveyor belt. The purpose is that when the conveyor belt transports a woven bag filled with feed to the opening knife, the woven bag will directly hit the blade of the opening knife, and the surface of the woven belt will be cut by the opening knife.

[0014] Furthermore, the opening knife includes a bevel frame, a blade, and a knife rod. The bevel frame is vertically fixedly mounted on the support of the conveyor belt, the crossbeam of the bevel frame is located directly above the conveyor belt, the blade is fixedly connected to the bottom end of the knife rod, the knife rod vertically passes through the crossbeam of the bevel frame and is slidably connected to the crossbeam of the bevel frame, and a spring is sleeved on the knife rod, the top end of the spring is fixedly connected to the bevel frame, and the bottom end of the spring is fixedly connected to the blade. The purpose is to form a support against the blade through the elastic force of the spring, so that the bottom end of the blade is close to the surface of the conveyor belt. When a woven bag filled with feed is conveyed, the spring can support the blade so that it can be closely attached to the surface of the woven bag to facilitate cutting. At the same time, when the woven bag hits the blade, the inclined blade can push the blade upward, so that it can be adapted to cut woven bags of different thicknesses.

[0015] Furthermore, the controller uses a single-chip microcomputer of the STM32F4 / F7 series. The purpose is that this single-chip microcomputer supports WiFi and has high computing power, which is suitable for image comparison.

[0016] Furthermore, the conveyor belt adopts a plate chain conveyor belt. The purpose is that the feed raw materials packed in woven bags have a certain weight, and the plate chain conveyor belt has a stronger supporting capacity. When the feed is unloaded at the discharge end of the conveyor belt, it is not easy to be seriously deformed due to the pull of the weight of the raw materials. BRIEF DESCRIPTION OF THE DRAWINGS
