Description

Technical Field

[0001] The invention relates to the technical field of production and processing of marine fish breeding feed, in particular to a marine fish breeding feed granulating device. Background Art

[0002] Marine fish are popular among consumers because of their delicious taste and rich nutrition. The market demand for marine fish has stimulated the development of the marine fish farming industry. Feed is an indispensable part of marine fish farming activities. In order to facilitate the consumption of marine fish and improve the palatability, this type of feed often needs to be processed by granulation equipment during the production process. However, there are still some problems in the actual operation of this type of granulation equipment.

[0003] Marine fish farming feed granulation devices are often simple in structure. They can only realize a single stirring and tumbling granulation process. It is not easy to improve the granulation accuracy by integrating the three-stage continuous granulation structure of extrusion molding, fixed-distance cutting granulation and granulation roller processing for feed raw materials. In addition, the granulation assembly is often open and easily contaminated by dust from the external environment, which affects the granulation quality. In view of the above problems, we propose a new type of marine fish farming feed granulation device. Summary of the invention

[0004] The object of the present invention is to provide a marine fish farming feed pelletizing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a marine fish breeding feed granulation device, comprising a feed pellet machine and a movable base plate, wherein a screw extruder is installed at one end of the feed pellet machine, a fixed frame is welded at the other end of the feed pellet machine, servo motors are installed on both sides of one end of the feed pellet machine, a granulation roller is connected to the inside of the feed pellet machine at the output end of the servo motor, a material receiving drawer is slidably connected to the bottom end of the feed pellet machine, an upper hopper is arranged on the top of the feed pellet machine, vertical hydraulic telescopic cylinders are evenly installed on the fixed frame, the movable base plate is connected to the output end of the vertical hydraulic telescopic cylinder, a transverse hydraulic telescopic cylinder is evenly installed on the movable base plate, the output end of the transverse hydraulic telescopic cylinder is connected to a dustproof protective shell, telescopic cylinders are installed on both sides of the inside of the dustproof protective shell, the output end of the telescopic cylinder is connected to a knife seat, a cutting knife is installed on the knife seat, and a laser ranging sensor is installed at one end of the inside of the dustproof protective shell.

[0006] Preferably, two granulation rollers are provided, and the outer side wall of the granulation roller and the inner side wall of the feed pellet machine are both provided with a Teflon non-stick layer.

[0007] Preferably, a pull-out structure is formed between the material collecting drawer and the feed pellet machine.

[0008] Preferably, a rubber sealing layer is vulcanized and connected to the edge of one side of the material receiving drawer.

[0009] Preferably, an electromagnetic lock matching the material receiving drawer is installed on the outer side wall of the feed pellet machine, so that it is easy to realize intelligent electromagnetic locking and closing of the material receiving drawer.

[0010] Preferably, the top of the upper hopper is threadedly connected with a material guiding cover body matching the dustproof protective shell, and the bottom of the dustproof protective shell is provided with an opening.

[0011] Preferably, a butt joint pipe is provided at the top of the dustproof protective shell, and a discharge port plugged into the butt joint pipe is provided at the output end of the feed pellet machine.

[0012] Preferably, two cutting knives are provided, and a disassembly and installation structure is formed between the cutting knives and the knife seat by screws.

[0013] According to the description of the technical solution, the technical solution has many beneficial technical effects, including: (1) The device optimizes its own performance by installing a screw extruder, etc. The screw extruder realizes strip extrusion molding of the pretreated feed. Then, the strip feed that has completed the preliminary molding process will be pelletized under the cutting structure composed of two sets of telescopic cylinders, a knife seat and a cutting knife inside the dustproof protective shell. The products cut into small pieces of particles will fall into the upper hopper on the top of the feed pellet machine. At this time, the two servo motors on the feed pellet machine start and drive the two pelletizing rollers to rotate inside the feed pellet machine. This can realize the further pelletization demand for the feed that has completed the preliminary pelletizing, so that the pellet feed of a qualified volume is discharged through the gap between the two pelletizing rollers. This enables the device to realize graded granulation processing, optimize the quality of the pellet feed finally formed, and make the granulation effect more precise.

[0014] (2) The device is equipped with a transverse hydraulic telescopic cylinder, etc., so that the device optimizes its own structure. On the one hand, by starting the transverse hydraulic telescopic cylinder installed on the fixed frame, the movable base plate and the dust protection shell can be automatically lifted up and down, and by starting the transverse hydraulic telescopic cylinder on the movable base plate, the dust protection shell can be automatically moved left and right. This can realize the positioning assembly or separation between the docking pipe and the bottom opening on the dust protection shell and the discharge port on the screw extruder and the material guide cover on the upper hopper. When assembled and connected together, it can ensure that the material discharged from the screw extruder directly enters the dust protection shell and then falls into the interior of the feed pellet machine. Finally, the material is taken out by pulling out the drawer for collecting the material. This makes the whole granulation process realize the advantage of being closed and reduces the pollution problem caused by the dust in the external environment adhering to the feed. On the other hand, by starting the vertical hydraulic telescopic cylinder and the transverse hydraulic telescopic cylinder, the dust protection shell can also be driven to separate from the screw extruder and the feed pellet machine, which is convenient for independent cleaning and maintenance of the dust protection shell, the screw extruder and the feed pellet machine.

[0015] (3) The device is equipped with a laser distance measuring sensor, etc., so that when the device is actually operated, the laser distance measuring sensor can monitor the distance between itself and the front end of the strip feed extruded by the screw extruder and extended into the inside of the butt tube in real time through the laser distance measuring principle. When the preset value is reached, the external control device will control the telescopic cylinder to drive the cutting knife to move and complete the cutting operation. This makes it possible to roughly control the pelletizing length during the pre-pelletizing operation, which is beneficial to ensure the uniform size of the feed and improve the processing effect.
