Description

Technical Field

[0001] This utility model relates to the field of fish farming technology, specifically to a fish grass crushing device. Background Technology

[0002] In the field of fish farming, the feed consumed by fish contains a large amount of fish grass. Fish grass can be used directly as a food source for fish, or it can be crushed and fed, or crushed and mixed with other feeds to be processed into pellets before feeding.

[0003] Currently, to improve nutritional balance, fish grass is usually crushed and mixed with other feeds to make nutritionally balanced feed. In this process, the fish grass needs to be crushed first. The commonly used equipment for crushing includes a crushing drum and a crushing rod. When using it, one or more types of fish grass are put into the crushing drum whole or in sections, and then the crushing rod is used to crush the fish grass in the crushing drum by moving up and down. However, this crushing structure still has shortcomings: 1. The fish grass has poor fluidity during the crushing process, which makes it impossible to crush it completely and continuously. It is necessary to frequently turn the feed manually, resulting in low crushing efficiency; 2. The crushed fish grass has a certain degree of moisture and viscosity, which makes it inconvenient to discharge.

[0004] Therefore, this utility model provides a fish grass crushing device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fish grass crushing device to solve the problems mentioned in the background technology. This utility model has the function of turning the material during the reciprocating crushing process, which improves the crushing efficiency, and also has the advantage of convenient discharge after crushing.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fish grass crushing device, comprising a base and a crushing cylinder and a crushing rod located above the base. The bottom of the crushing cylinder is provided with a spherical groove, and a turntable is fitted onto the top opening of the crushing cylinder. One side of the turntable is connected to a scraper that fits against the inner wall of the crushing cylinder. A bottom plate is provided at the bottom of the crushing cylinder, and one side of the bottom plate is rotatably connected to the outer peripheral wall of the crushing cylinder. The spherical groove is located on one side of the bottom plate, and a control assembly for controlling the rotation of the bottom plate is provided on one side of the crushing cylinder.

[0007] Furthermore, the outer peripheral wall of the tamping cylinder is fixedly connected to the bracket and the base. A control motor is installed on the bracket, and a drive gear is fixedly connected to the output shaft of the control motor. A gear ring that meshes with the drive gear is fixedly sleeved on the outside of the turntable.

[0008] Furthermore, the scraper has a V-shaped cross-section with its larger end facing the inner wall of the tamping cylinder.

[0009] Furthermore, rubber scrapers are adhered to both the left and right sides of the scraper.

[0010] Furthermore, an arm is fixedly connected to the outer peripheral wall of the base plate, and a hinge seat is fixedly connected to one end of the arm to the outer peripheral wall of the tamping cylinder.

[0011] Furthermore, the control assembly includes a slider and a lead screw. The slider is slidably mounted on the base and located below the tamping cylinder. A pad adapted to the outer side of the base plate is fixedly connected to the top of the slider. The lead screw and the bracket are rotatably connected and screwed through the slider.

[0012] Furthermore, a rubber ring that seals with the bottom plate is bonded to the bottom end of the tamping cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a turntable is set at the mouth of the tamping cylinder. By setting a scraper on the turntable that fits against the inner wall of the tamping cylinder on one side, the fish grass that is close to the inner wall of the tamping cylinder can be separated when the turntable rotates. This allows all the fish grass to be tamped by the tamping rod in turn, eliminating the need for manual turning and greatly improving the processing efficiency.

[0015] 2. In this utility model, a bottom plate is provided at the bottom of the tamping cylinder, and a spherical groove is located on the bottom plate. By setting the bottom plate into a structure that is connected by rotation between the upper and lower parts, the broken material inside the tamping cylinder will fall off under the push of the scraper after the bottom plate is opened, which has the advantage of more efficient and thorough material feeding.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a fish grass crushing device, including a base 3 and a crushing cylinder 1 and a crushing rod 2 located above the base 3. The base 3 serves to support the device. The bottom of the crushing cylinder 1 is provided with a spherical groove 11, which is the area to be crushed by the crushing rod 2. In the prior art, fish grass is usually put into the crushing cylinder 1 and then the crushing rod 2 is used to repeatedly crush the fish grass above the spherical groove 11.

[0022] In this technical solution, a turntable 7 is fitted at the top opening of the tamping cylinder 1. The turntable 7 is ring-shaped and is fitted outside the tamping cylinder 1. One side of the turntable 7 is connected to a scraper 4 that fits against the inner wall of the tamping cylinder 1. The bottom of the scraper 4 extends to the top opening of the spherical groove 11. When the turntable 7 rotates, the scraper 4 can scrape away the fish grass attached to the inner circumferential wall of the tamping cylinder 1 and let it enter the spherical groove 11, so that the fish grass can be hammered.

[0023] In practice, the outer periphery of the tamping cylinder 1 is fixedly connected to the support 9 and the base 3. The support 9 is a portal frame, with a support plate fixedly connected inside and to the outer wall of the tamping cylinder 1. A control motor 8 is mounted on the support plate, and a drive gear 81 is fixedly connected to the output shaft of the control motor 8. A gear ring 71 that meshes with the drive gear 81 is fixedly fitted on the outside of the turntable 7. The control motor 8 provides driving force to the rotation of the turntable 7. It should be noted that a common crank-rocker mechanism can be installed on the top of the support 9 to control the up-and-down movement of the tamping rod 2.

[0024] The bottom of the tamping cylinder 1 is provided with a base plate 5, one side of which is rotatably connected to the outer peripheral wall of the tamping cylinder 1. In this embodiment, the base plate 5 and the tamping cylinder 1 rotate up and down. In a specific implementation, it is preferred that the outer peripheral wall of the base plate 5 is fixedly connected to an arm 51, and the outer peripheral wall of the tamping cylinder 1 is fixedly connected to a hinge seat 13 that is hinged to one end of the arm 51. The spherical groove 11 is located on one side of the base plate 5. After the base plate 5 is rotated down and opened, the fish grass in the tamping cylinder 1 can easily fall off under the scraping of the scraper 4. When in use, a receiving basin can be placed on the base 3 to receive the fallen crushed fish grass.

[0025] One side of the tamping cylinder 1 is equipped with a control assembly 6 for controlling the rotation of the base plate 5.

[0026] Specifically, the control assembly 6 includes a slider 61 and a lead screw 62. The slider 61 is slidably mounted on the base 3 and located below the tamping cylinder 1. In practice, a groove adapted to the slider 61 can be opened on the upper surface of the base 3. A pad 611 adapted to the outer side of the base plate 5 is fixedly connected to the top of the slider 61. The lead screw 62 is rotatably connected to the bracket 9 and is screwed through and engaged with the slider 61. When the lead screw 62 rotates, it can control the slider 61 to slide. When the slider 61 slides, it can push the base plate 5 to close and open. When opening, the weight of the base plate 5 is used. In use, a throttle can be welded to one end of the lead screw 62.

[0027] In this embodiment, the scraper 4 has a V-shaped cross-section with its larger end facing the inner wall of the tamping cylinder 1. This design can significantly push away the fish grass attached to the inner wall of the tamping cylinder 1, thereby improving the reliability of removing the fish grass.

[0028] Furthermore, rubber scraper blades 41 are attached to both the left and right sides of the scraper 4. The function of the rubber scraper blades 41 is to scrape more thoroughly and reduce residue.

[0029] In this embodiment, a rubber ring 12 is bonded to the bottom end of the bottom plate 5 and the tamping cylinder 1 to seal with the bottom plate 5. After the bottom plate 5 is closed, the rubber ring 12 will be squeezed, thereby preventing liquid leakage when the fish grass is crushed.

[0030] Working principle: During use, the control rod 2 is raised, increasing the space at the opening of the tamping cylinder 1. Then, fish grass is placed into the tamping cylinder 1. The control rod 2 is then moved up and down repeatedly, crushing the fish grass in the spherical groove 11. At the same time, the control motor 8 is started, the turntable 7 rotates, and the scraper 4 scrapes the fish grass off the inner wall of the tamping cylinder 1. The fish grass falls below the tamping rod 2 and is pounded. After crushing is completed, the control screw 62 is rotated to move the slider 61 away from the bottom plate 5. At this time, the bottom plate 5 opens by its own weight, and the crushed fish grass in the spherical groove 11 falls out. The fish grass in the tamping cylinder 1 falls out under the scraper 4. At this time, the crushing and feeding of fish grass is completed.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
