Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture equipment, and more specifically, relates to a slow-sinking feed pelleting device for mandarin fish. Background Technology
[0002] The slow-sinking feed pelleting device for mandarin fish is a specialized piece of equipment designed for the feeding habits and nutritional needs of mandarin fish. It is used to produce pellet feed that sinks slowly in water, which can satisfy the feeding habits of mandarin fish and reduce feed waste and water pollution.
[0003] When using a feed pelleting device to pellet slow-sinking feed for mandarin fish, oil needs to be added to the pelleting bin to reduce the density of the feed and enhance the hydrophobicity of the feed surface to a certain extent. However, feed mixed with oil has a certain stickiness when it is not dried, which can easily clog the die of the pelleting device and reduce the working efficiency of the pelleting device. Utility Model Content
[0004] The main purpose of this invention is to provide a pelleting device for slow-sinking feed specifically for mandarin fish.
[0005] According to a first aspect of the present invention, a slow-sinking feed pelleting device for mandarin fish is provided, comprising a movable plate, a base mounted on one side of the top of the movable plate, a pelleting bin mounted on the top of the base, a feed hopper mounted on the top of the pelleting bin, an oil inlet pipe mounted on the outer surface of the pelleting bin, a discharge cylinder mounted on the bottom of the outer surface of the pelleting bin, a pelleting assembly disposed on the other side of the top of the base, and an auxiliary device disposed on the outer surface of the pelleting bin. The auxiliary device uses two auxiliary plates to tap the sides of the pelleting bin, assisting the feed in the die inside the pelleting bin to detach from the die.
[0006] By setting up two auxiliary plates and adjusting them, the two auxiliary plates can strike the pelleting chamber. When the pelleting chamber is struck, it vibrates, which helps the feed inside the die to detach from the die. This helps prevent the die from being blocked, which would reduce the working efficiency of the pelleting device.
[0007] According to the first aspect embodiment of the present invention, the slow-sinking feed pelleting device for mandarin fish includes two auxiliary plates symmetrically arranged on the outer surface of the pelleting chamber. An L-shaped plate is symmetrically installed at the bottom of the outer surface of the pelleting chamber. The auxiliary plates are slidably installed on the inner wall of the L-shaped plate. An extension block is fixedly installed on one side of the L-shaped plate. A wire body is fixedly installed on the side of the two extension blocks that are close to each other. A wire wheel is rotatably installed on the top of the discharge cylinder. One end of each of the two wire bodies is inserted into the outer surface of the wire wheel.
[0008] Rotating the spool causes the spool to wind the spool around its outer surface. The spool then drives the auxiliary plates connected to the extension block to move in opposite directions until one side of the two auxiliary plates hits the outer surface of the granulation chamber. This causes the granulation chamber to vibrate, which in turn helps the material to detach from the inner wall of the die.
[0009] According to the first aspect embodiment of the present invention, a slow-sinking feed pelleting device for mandarin fish is provided, in which springs are fixedly installed on the opposite sides of the two auxiliary plates, and one end of each spring is fixedly installed on one side of the L-shaped plate.
[0010] By setting a spring, when the two auxiliary plate rollers approach each other, the auxiliary plate will stretch the spring, causing the spring to deform. When the force applied to the rollers is removed, the spring will reset and move the auxiliary plate away from the granulation chamber. When the auxiliary plates move away from each other, the granulation material will loosen on the rollers. This makes it easier to repeat the operation of the auxiliary plates multiple times, so that the auxiliary plates can hit the granulation chamber multiple times, making it easier for the material to leave the die.
[0011] According to the first aspect embodiment of the present invention, a slow-sinking feed pelleting device for mandarin fish is provided inside the spring. One end of the round rod is fixedly installed on one side of the auxiliary plate, and the round rod is slidably installed on the inner wall of the L-shaped plate. By providing the round rod, it can limit and guide the spring, which helps to prevent the spring from bending during deformation.
[0012] According to the slow-sinking feed pelleting device for mandarin fish described in the first aspect of this utility model, rubber plates are adhered to the adjacent sides of the two auxiliary plates. By setting the rubber plates, one side of the auxiliary plates abuts against the outer surface of the pelleting chamber, which can provide a certain degree of protection to the pelleting chamber when the auxiliary plates strike the outer surface of the pelleting chamber.
[0013] According to the first aspect embodiment of the present invention, a slow-sinking feed pelleting device for mandarin fish is provided with a handwheel fixedly installed on the top of the reel, and the outer surface of the handwheel is provided with protrusions. By providing the handwheel, rotating the handwheel can drive the reel to rotate, and the protrusions on the outer surface of the handwheel can effectively increase the friction of the outer surface of the handwheel, thus providing an anti-slip effect when rotating the handwheel.
[0014] According to the first aspect embodiment of the present invention, a slow-sinking feed pelleting device for mandarin fish is provided, wherein a feed line is symmetrically installed on the top of the discharge cylinder, and the feed line is disposed inside a limiting block. By setting the limiting block, the movement direction of the feed line is assisted in limiting, so that the feed line can move along a specific trajectory during the rotation of the feed reel.
[0015] According to the slow-sinking feed pelleting device for mandarin fish described in the first aspect of this utility model, a rubber ring is installed on the inner wall of the limiting block, and the feed line is disposed inside the rubber ring. By setting the rubber ring, the rubber ring can provide a certain degree of protection for the feed line, which helps to reduce the damage caused to the feed line by the limiting block when the feed line comes into contact with and rubs against the inner wall of the limiting block.
[0016] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:
[0017] In this slow-sinking feed pelleting device for mandarin fish, two auxiliary plates are set up and adjusted so that the two auxiliary plates strike the pelleting chamber. When the pelleting chamber is struck, it vibrates, which helps the feed on the inner wall of the die to detach from the die. This helps to prevent the die from being blocked, which would reduce the working efficiency of the pelleting device. Attached Figure Description

[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.
[0029] Reference Figures 1 to 4As shown, a slow-sinking feed pelleting device for mandarin fish is provided, including a movable plate 1, a base 2 installed on one side of the top of the movable plate 1, a pelleting bin 3 installed on the top of the base 2, a feed hopper 4 installed on the top of the pelleting bin 3, an oil inlet pipe 5 installed on the outer surface of the pelleting bin 3, for adding materials such as oil into the oil inlet pipe 5 to mix into the feed, thereby reducing the density of the feed and enhancing the hydrophobicity of the feed surface to a certain extent, thus improving the slow-sinking characteristics of the feed. A discharge cylinder 6 is installed at the bottom of the outer surface of the pelleting bin 3, and a pelleting component 8 is provided on the other side of the top of the base 2 (the pelleting component 8 can be a motor installed on one side of the top of the base plate, the motor being connected to the pressure plate inside the pelleting bin 3 through components such as a reducer, so that the pressure plate squeezes the feed). The die inside the pelleting chamber 3 is used to compress and shape the feed. The shaped feed enters the discharge cylinder 6 through the die. (Since motor-driven feed pelleting is a conventional technology, it will not be elaborated on here.) An auxiliary device 7 is provided on the outer surface of the pelleting chamber 3. The auxiliary device 7 uses two auxiliary plates 71 to strike the sides of the pelleting chamber 3, which helps the feed in the die inside the pelleting chamber 3 to detach from the die. By setting two auxiliary plates 71 and adjusting them, the two auxiliary plates 71 strike the pelleting chamber 3. When the pelleting chamber 3 is struck, it vibrates, which helps the feed on the inner wall of the die to detach from the die. This helps to prevent the die from being blocked, which would reduce the working efficiency of the pelleting device.
[0030] Reference Figures 2 to 4As shown, in some embodiments of this utility model, the auxiliary device 7 includes two auxiliary plates 71, which are symmetrically arranged on the outer surface of the granulation chamber 3. An L-shaped plate 72 is symmetrically installed at the bottom of the outer surface of the granulation chamber 3. The auxiliary plates 71 are slidably installed on the inner wall of the L-shaped plate 72. An extension block 73 is fixedly installed on one side of the L-shaped plate 72. A wire body 74 is fixedly installed on the side of each of the two extension blocks 73 that are close to each other. A wire reel 75 is rotatably installed on the top of the discharge cylinder 6. One end of each of the two wire bodies 74 is inserted into the outer surface of the wire reel 75. When the wire reel 75 is rotated, the wire reel 75 winds the wire body 74 around its outer surface. The wire body 74 drives the auxiliary plates 71 connected to the extension blocks 73 to move towards each other until one side of the two auxiliary plates 71 impacts the granulation chamber 3. The outer surface of the granulation chamber will cause the granulation chamber to vibrate, thereby assisting the material to detach from the inner wall of the die. Springs 76 are fixedly installed on the opposite sides of the two auxiliary plates 71. One end of the spring 76 is fixedly installed on one side of the L-shaped plate 72. By setting the spring 76, when the action of the two auxiliary plates 71 and the rollers 75 approaches each other, the auxiliary plates 71 will stretch the spring 76, causing the spring 76 to deform. When the force applied to the rollers 75 is removed, the spring 76 will reset and drive the auxiliary plates 71 away from the granulation chamber. When the two auxiliary plates 71 move away from each other, the wire body 74 will loosen on the rollers 75. This makes it easy to repeat the operation of the auxiliary plates 71 multiple times, so that the auxiliary plates 71 can hit the granulation chamber 3 multiple times, making it easier for the material to detach from the die.
[0031] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, a round rod 77 is provided inside the spring 76. One end of the round rod 77 is fixedly installed on one side of the auxiliary plate 71, and the round rod 77 is slidably installed on the inner wall of the L-shaped plate 72. By setting the round rod 77, the round rod 77 can limit and guide the spring 76, which helps to prevent the spring 76 from bending during deformation. Rubber plates 78 are glued to the side of the two auxiliary plates 71 that are close to each other. By setting the rubber plates 78, one side of the auxiliary plate 71 is in contact with the outer surface of the granulation chamber, which can provide a certain degree of protection to the granulation chamber when the auxiliary plate 71 hits the outer surface of the granulation chamber.
[0032] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, a handwheel 79 is fixedly installed on the top of the spool 75. The outer surface of the handwheel 79 is provided with protrusions. By setting the handwheel 79, rotating the handwheel 79 can drive the spool 75 to rotate. At the same time, the protrusions on the outer surface of the handwheel 79 can effectively increase the friction of the outer surface of the handwheel 79, which has an anti-slip effect when rotating the handwheel 79.
[0033] In some embodiments of this utility model, reference is made to Figure 2and Figure 3 As shown, a wire body 74 is symmetrically installed on the top of the discharge cylinder 6. The wire body 74 is located inside the limiting block 710. By setting the limiting block 710, the movement direction of the wire body 74 is assisted and limited, so that the wire body 74 can move on a specific trajectory during the rotation of the wire wheel 75. A rubber ring 711 is installed on the inner wall of the limiting block 710, and the wire body 74 is located inside the rubber ring 711. By setting the rubber ring 711, the rubber ring 711 can play a certain protective role for the wire body 74, which helps to reduce the damage caused to the wire body 74 by the limiting block 710 when the wire body 74 comes into contact with the inner wall of the limiting block 710.
[0034] Turning the handwheel 79 causes the thread reel 75 to rotate, which in turn winds the thread 74 around its outer surface. The thread 74 then moves the auxiliary plates 71, connected to the extension block 73, towards each other. The auxiliary plates 71 stretch the spring 76, causing it to deform until the rubber plates 78 on one side of the two auxiliary plates 71 strike the outer surface of the granulation chamber. At this point, the force applied to the handwheel 79 is released, and the spring 76 returns to its original position, moving the auxiliary plates 71 away from the granulation chamber. As the two auxiliary plates 71 move away from each other, they cause the thread 74 to move along the thread reel 75. If loosening occurs, repeat the above operation, causing the auxiliary plate 71 to continuously strike the outer surface of the granulation chamber, which will cause the granulation chamber to vibrate, thereby helping the material to detach from the inner wall of the die. The limiting block 710 can assist in limiting the movement direction of the line 74, so that the line 74 can move on a specific trajectory during the rotation of the reel 75. The rubber ring 711 on the inner wall of the limiting block 710 can play a certain protective role for the line 74, which helps to reduce the damage to the line 74 caused by the limiting block 710 when the line 74 comes into contact with the inner wall of the limiting block 710.
[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
