Description

Technical Field

[0001] The present invention belongs to the technical field of shrimp breeding, and specifically relates to a continuous forming device for granular feed for shrimp breeding. Background Art

[0002] Conventional granulation equipment for shrimp feed mainly consists of a forming tank, a screw feeding device, and a cutting component. During forming, the semi-finished feed raw materials are pressurized by the screw feeding device and then come into contact with the forming plate, and are discharged through the forming holes. The granular form is achieved by a rotating cutting knife. This forming method is limited by the cutting rate and the viscosity of the feed. During rotary cutting, some feed adheres to the cutting knife, resulting in the feed being unable to form, affecting the forming quality. At the same time, it is also impossible to keep the cutting knife always close to the forming plate, further affecting its forming quality.

[0003] Moreover, during the long-term cutting process, some feed debris adheres to the cutting knife and needs to be cleaned. In the prior art, the cutting knife is generally cleaned regularly, but when facing batch processing, the entire cleaning time is time-consuming. At the same time, the cutting knife is relatively sharp, posing a certain safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous forming device for granular feed for shrimp breeding to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A continuous forming device for granular feed for shrimp breeding, including a forming tank assembly. The forming tank assembly includes a tank body. The front surface of the tank body is installed with a forming plate through bolts. One side of the front surface of the forming plate is provided with a groove. The front surface of the forming plate is circumferentially provided with forming holes. Both left and right sides of the inner cavity of the groove are provided with limiting grooves. The top end of the tank body is fixedly installed with a locking frame located directly above the groove. The inner side surface of the locking frame is fixedly sleeved with a self-cleaning component. A power shaft is movably installed in the middle of the forming plate. The front surface of the power shaft penetrates through the front surface of the forming plate and is fixedly installed with a cutting component. An adjusting component is fixedly installed at a position on the front surface of the cutting component close to the power shaft. The self-cleaning component is movably clamped with the limiting groove at a position close to the bottom end. When the cutting component is located inside the groove, the outer side surface of the cutting component is in contact with the bottom end of the self-cleaning component. A machine base is installed at the bottom end of the outer side surface of the tank body.

[0006] In the initial state, the cutting component is not located inside the groove, and the rear end of the cutting component is in contact with the front surface of the groove. At this time, the device is in the cutting state, and the mixed semi-solid feed is prepared before cutting. At the same time, it is necessary to ensure that the aperture of the forming hole meets the specification requirements of the granular feed to complete the preparation before processing.

[0007] As a further technical solution of the present invention, a feeding tank is fixedly communicated at a position near the rear end of the top end of the tank body. A main shaft is movably installed in the middle of the tank body. The front end of the main shaft is connected to a power shaft. A spiral feeding blade located inside the tank body is fixedly sleeved on the outer side surface of the main shaft.

[0008] As a further technical solution of the present invention, a motor base is fixedly installed at the rear end of the tank body. A main motor is fixedly installed on the inner side surface of the motor base. The output end of the main motor is connected to the main shaft.

[0009] When forming granular feed, the semi-solid granular feed is injected into the interior of the tank body through the feeding tank. At the same time, the main motor is turned on to drive the main shaft to rotate. At this time, the spiral feeding blade on the outer side surface of the main shaft rotates accordingly, and the feed is evenly transported to the rear end of the groove. After being extruded by the groove, the feed is pressed out through the forming holes. At this time, the main shaft can synchronously drive the power shaft to rotate. When the power shaft rotates, it can drive the cutting knife to rotate. At this time, the cutting knife can rotate relative to the groove to perform circumferential cutting on the extruded feed, cutting the feed into granular shape, and completing the forming process.

[0010] As a further technical solution of the present invention, a first three-way valve is fixedly communicated at the front end of the adjusting assembly. A negative pressure pump is installed at the front end of the first three-way valve. The output end of the negative pressure pump is communicated with the front end of the first three-way valve. The adjusting assembly includes an adjusting pipe. An adjusting plate is movably sleeved inside the adjusting pipe. One end of the adjusting plate away from the first three-way valve is fixedly installed with an adjusting rod.

[0011] As a further technical solution of the present invention, one end of the adjusting rod away from the adjusting plate penetrates through one end of the adjusting pipe and is connected to the cutting assembly. A limiting spring is movably sleeved on the outer side surface of the adjusting rod. The front and rear ends of the limiting spring are respectively connected to one end of the adjusting plate and one end of the inner cavity of the adjusting pipe.

[0012] As a further technical solution of the present invention, the cutting assembly includes a cutting knife. The back surface of the cutting knife is connected to the front surface of the power shaft. A distribution cavity is opened inside the cutting knife. Nozzles are fixedly communicated at equal intervals at the left and right ends of the distribution cavity. A second three-way valve is fixedly communicated at the front surface of the distribution cavity.

[0013] As a further technical solution of the present invention, the bottom end of the second three-way valve is communicated with the top end of the first three-way valve through a pipeline. When the cutting assembly rotates to correspond to the self-cleaning assembly and is located inside the groove, the top end of the second three-way valve is communicated with the self-cleaning assembly.

[0014] During the rotary cutting process, the external blower can be turned on to compress the external air and input it into the interior of the first three-way valve. At this time, the valve at the top of the first three-way valve is opened to introduce the compressed air into the interior of the second three-way valve, and the valve at the rear end of the second three-way valve is opened to make the compressed air enter the interior of the distribution chamber. At this time, the distribution chamber is filled with compressed air, and the nozzle can be opened to make the compressed air be exported through both ends of the granulating knife and act near the granular feed to be cut, cooling it while using the flowing air to reduce adhesion.

[0015] By utilizing the generated compressed air, directly introducing the compressed air into the rotating granulating knife, and exporting it through the nozzles at both ends, when the granulating knife rotates and cuts, compressed air can be discharged from both ends and act on the granular feed. The flowing air is used to assist in cooling and reducing the adhesion between the granular feed and the granulating knife, improving the forming quality of the granular feed.

[0016] At the same time, when the granulating knife rotates and cuts, the valve of the first three-way valve can be opened to input the compressed air into the interior of the adjusting pipe. At this time, the adjusting plate and the adjusting rod move towards the direction close to the groove, the limiting spring is compressed at this time, and at the same time, the granulating knife is driven to move backward, and the power shaft is compressed at this time, making the granulating knife tightly adhere to the groove, reducing the gap, and ensuring the uniformity of the granular feed after cutting.

[0017] By further utilizing the input compressed air, through the pressure of the compressed air and the cooperation between the adjusting component and the granulating component, when the granulating knife rotates and cuts, it can tightly adhere to the surface of the groove, ensuring the uniformity of each granular feed when the feed is formed, significantly improving the forming quality of the granular feed, and reducing the unqualified rate.

[0018] As a further technical solution of the present invention, the self-cleaning component includes a pressure pipe, the outer side surface of the pressure pipe is fixedly sleeved with a locking frame, the top end of the pressure pipe is fixedly communicated with a pressure elbow pipe, the pressure elbow pipe is communicated with the second three-way valve, and a pressure plate is movably sleeved inside the pressure pipe.

[0019] As a further technical solution of the present invention, the bottom end of the pressure plate is fixedly connected with a pressure rod, the bottom end of the pressure rod penetrates through the bottom end of the pressure pipe and is fixedly connected with a pressure frame, and a return spring is movably sleeved on the outer side surface of the pressure rod. The upper and lower ends of the return spring are respectively connected with the bottom end of the pressure plate and the top end of the inner cavity of the pressure pipe.

[0020] As a further technical solution of the present invention, extension rods are installed on both the left and right sides of the bottom end of the pressure frame, and cleaning brushes are fixedly installed at the bottom ends of the extension rods. When the granulating knife is located inside the groove, the inner side surface of the cleaning brush is in contact with the outer side surface of the granulating knife, and the outer side surface of the cleaning brush is movably clamped with the limiting groove.

[0021] When a certain amount of feed debris adheres to the surface of the pelletizing knife and affects cutting, the pelletizing knife can be rotated to the front of the groove, and the valve at the rear end of the first three-way valve can be continuously opened to inject more compressed air into the inside of the regulating pipe. At this time, the limiting spring is compressed to the limit state, and the pelletizing knife is continuously pushed backward until the pelletizing knife enters the inside of the groove. At this time, the outer side of the pelletizing knife contacts the two cleaning brushes. At this time, the top of the second three-way valve is connected to the pressure elbow, and the compressed air enters the inside of the pressure elbow and drives the pressure plate to move downward. At this time, the return spring is compressed, and at the same time, the pressure rod and the pressure bracket are driven to move downward, and the extension rod and the cleaning brush move downward synchronously and contact the outer side of the pelletizing knife to actively friction-clean the outer side of the pelletizing knife, completing the self-cleaning process.

[0022] Through the further utilization of compressed air and the cooperation between the regulating component, the pelletizing component and the self-cleaning component, the pelletizing component can regularly enter the inside of the groove and complete the active cleaning process through the self-cleaning component. The entire cleaning process can be automatically completed without regular manual cleaning. At the same time, the cleaning process runs automatically, which can avoid the phenomenon of hurting people, reduce potential safety hazards, reduce the maintenance difficulty, and improve safety.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) By utilizing the generated compressed air, directly introducing the compressed air into the rotating pelletizing knife, and discharging it through the nozzles at both ends, when the pelletizing knife rotates and cuts, compressed air can be discharged at both ends and act on the pellet feed. The flowing air assists in cooling the pellet feed and reducing its adhesion to the pelletizing knife, improving the forming quality of the pellet feed.

[0025] (2) By further utilizing the input compressed air, through the pressure of the compressed air and the cooperation between the regulating component and the pelletizing component, when the pelletizing knife rotates and cuts, it can closely adhere to the surface of the groove, ensuring the uniformity of each pellet feed when the feed is formed, significantly improving the forming quality of the pellet feed, and reducing the unqualified rate.

[0026] (3) By further utilizing the compressed air and the cooperation between the regulating component, the pelletizing component and the self-cleaning component, the pelletizing component can regularly enter the inside of the groove and complete the active cleaning process through the self-cleaning component.

[0044] Embodiment: During the rotary cutting process, the external fan can be turned on to compress the external air and input it into the interior of the No. 1 three-way valve 11.

The entire cleaning process can be automatically completed without regular manual cleaning. At the same time, the cleaning process runs automatically, which can avoid the phenomenon of hurting people, reduce potential safety hazards, reduce the maintenance difficulty, and improve safety.

[0051] Working principle and usage process:

[0052] In the initial state, the pelletizing assembly 15 is not located inside the groove 102, and the rear end of the pelletizing assembly 15 contacts the front of the groove 102. At this time, the device is in the cutting state, and the mixed semi-solid feed is prepared before cutting. At the same time, it is necessary to ensure that the aperture of the forming hole 104 meets the specification requirements of the pellet feed to complete the preparation before processing;

[0053] When forming the pellet feed, the semi-solid pellet feed is injected into the inside of the tank body 101 through the feeding tank 3. At the same time, the main motor 5 is turned on to drive the main shaft 6 to rotate. At this time, the spiral feeding blade 7 on the outer side surface of the main shaft 6 rotates accordingly, and the feed is evenly transported to the rear end of the groove 102. After being extruded through the groove 102, the feed is extruded through the forming hole 104. At this time, the main shaft 6 can synchronously drive the power shaft 13 to rotate. When the power shaft 13 rotates, the pelletizing knife 151 can be driven to rotate. At this time, the pelletizing knife 151 can rotate relative to the groove 102 to circularly cut the extruded feed and cut the feed into granular form, completing the forming process;

[0054] During the rotary cutting process, the external blower can be turned on to compress the external air and input it into the interior of the first three-way valve 11. At this time, the valve at the top of the first three-way valve 11 is opened to introduce the compressed air into the interior of the second three-way valve 14, and the valve at the rear end of the second three-way valve 14 is opened to allow the compressed air to be introduced into the interior of the distribution chamber 152. At this time, the distribution chamber 152 is filled with compressed air, and the nozzle 153 can be opened to allow the compressed air to be exported through both ends of the granulating knife 151 and act near the granular feed to be cut, cooling it while using the flowing air to reduce adhesion.

[0055] Meanwhile, when the granulating knife 151 is rotating for cutting, the valve of the first three-way valve 11 can be opened to input the compressed air into the interior of the adjusting pipe 121. At this time, the adjusting plate 122 and the adjusting rod 123 move towards the direction close to the groove 102, the limiting spring 124 is compressed at the same time, and the granulating knife 151 is driven to move backward. At this time, the power shaft 13 is compressed, so that the granulating knife 151 is pressed against the groove 102, reducing the gap and ensuring the uniformity of the granular feed after cutting.

[0056] When a certain amount of feed debris adheres to the surface of the granulating knife 151 and affects cutting, the granulating knife 151 can be rotated to the front of the groove 102, and the valve at the rear end of the first three-way valve 11 is continuously opened to inject more compressed air into the interior of the adjusting pipe 121. At this time, the limiting spring 124 is compressed to the limit state, and the granulating knife 151 is continuously pushed to move backward until the granulating knife 151 enters the interior of the groove 102. At this time, the outer side surface of the granulating knife 151 comes into contact with the two cleaning brushes 908.
