Description

Technical Field

[0001] This utility model relates to the field of fish and shrimp processing technology, and in particular to a waste fish and shrimp crushing device. Background Technology

[0002] In fisheries and aquaculture, low-value fish and shrimp can be ground up and used as high-protein feed for raising other aquatic animals, which can improve resource utilization. In some cases, in order to reduce environmental impact, small fish and shrimp produced during the fishing process are ground up and used as organic fertilizer.

[0003] To facilitate the crushing of waste fish and shrimp, a waste fish and shrimp crushing device is proposed, such as the prior art Chinese Patent Publication No. "CN216025192U"—a flexibly adjustable crushing device for processing fish and shrimp feed. This device includes a chamber, inside which a first filter plate is fixedly installed. A cleaning mechanism, extending through and into the chamber, is fixedly installed on the right side of the chamber. An adjustment mechanism is provided on the chamber. A crushing mechanism is fixedly installed inside the chamber, above the first filter plate. A vibrator is provided on the adjustment mechanism. The adjustment mechanism includes a spring telescopic rod, which is fixedly installed on the left side of the inner wall of the chamber, below the first filter plate. This flexibly adjustable crushing device for processing fish and shrimp feed allows users to easily adjust the size of the filter holes in the first filter plate, enabling the screening and collection of feed of different sizes. This greatly improves the device's efficiency in crushing and collecting feed, making it highly practical.

[0004] In actual operation, the cylinder-driven pusher uses the brush plate to clean the minced meat and the sieve plate. However, after a long period of use, the brush plate is prone to aging and damage. It is inconvenient to replace the brush plate, or the brush plate needs to be replaced together with the pusher plate, which will affect the processing efficiency of fish and shrimp and increase the replacement and maintenance costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of replacing and maintaining the brush plate, by proposing a waste fish and shrimp crushing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a waste fish and shrimp crushing device, including a shell, inside which a crushing device and a separating component are arranged. The crushing device works with the separating component to crush fish and shrimp and separate the fish and shrimp meat into solid and liquid components.

[0008] The housing also includes a cleaning assembly, which includes a push plate for cleaning minced meat and a brush plate detachably connected to the bottom.

[0009] Furthermore, the separating component is a sieve plate, which is fixed to the housing below the crushing device by fasteners.

[0010] Furthermore, the cleaning assembly also includes a cylinder. A discharge port is provided on one side of the bottom of the housing, and the cylinder is fixedly installed on the other side. The push plate is fixedly connected to the shaft end of the cylinder. A pair of guide rods and the brush plate are provided at the bottom of the push plate through a sliding groove. The brush plate abuts against the screen plate.

[0011] Furthermore, the two ends of the brush plate are extended to form extension portions, and the extension portions on both sides are provided with through grooves at opposite ends. The free end of the guide rod is slidably connected to the extension portion through the through groove, and a spring is also sleeved around it, with the spring abutting against the extension portion.

[0012] Furthermore, the extension is provided with a stepped groove on the opposite side of the through groove, wherein the free end of the guide rod is rotatably connected to a limiting part, the limiting part avoids the extension through the through groove, and is rotatably disposed in the stepped groove.

[0013] Furthermore, a guide plate is fixedly connected to the discharge port of the housing.

[0014] The present invention provides a waste fish and shrimp crushing device with the following advantages: the crushing device can effectively crush fish and shrimp, and the screen plate can separate the minced meat and blood. The minced meat after separating the blood is beneficial for subsequent processing. In addition, while the minced meat is fed by the push plate, the screen plate can be cleaned by the brush plate to avoid the screen plate being blocked by the minced meat and affecting its use. The push plate and the screen plate can be quickly replaced, avoiding the cumbersome disassembly and assembly process that affects the crushing efficiency of fish and shrimp. The structure is simple, the operation is convenient, and the practicality is strong. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A waste fish and shrimp crushing device includes a shell 1, and a crushing device 2 and a separating component 3 are arranged inside the shell 1. The crushing device 2 works with the separating component 3 to crush fish and shrimp and separate the fish and shrimp meat into solid and liquid components.

[0023] The housing 1 is further provided with a cleaning component 4, which includes a push plate 41 for cleaning meat paste and a brush plate 42 detachably connected to the bottom.

[0024] It should be added that the crushing device 2 includes a rotating shaft, which is rotatably connected to the feed inlet of the housing 1 and has several rows of crushing discs around its periphery. It also includes a motor, which is fixed to the back of the housing 1, and a transmission pulley is fixedly connected between its shaft end and the rotating shaft. A pair of transmission pulleys are driven by a transmission belt.

[0025] Among them, solid-liquid separation refers to separating the pulverized fish and shrimp meat from the blood, which facilitates the subsequent processing of the fish and shrimp. In addition, the bottom of the shell 1 is recessed below the sieve plate to form a water collection tank, and a drain pipe is connected to the water collection tank. An electric valve is installed in the drain pipe.

[0026] Furthermore, the separating component 3 is a sieve plate, which is fixed to the housing 1 below the crushing device 2 by fasteners. The fasteners are locking bolts and baffles, and the baffles are fixedly connected to the housing 1 by the locking bolts, thereby fixing the sieve plate.

[0027] Furthermore, the cleaning component 4 also includes a cylinder 43. A discharge port is provided on one side of the bottom of the housing 1, and the cylinder 43 is fixedly installed on the other side. The shaft end of the cylinder 43 is fixedly connected to the push plate 41. The bottom of the push plate 41 is provided with a pair of guide rods 44 and the brush plate 42 through a sliding groove. The brush plate 42 abuts against the screen plate.

[0028] More specifically, the two ends of the brush plate 42 are extended to form extension portions 421. The extension portions 421 on both sides have through grooves 422 at opposite ends. The free end of the guide rod 44 is slidably connected to the extension portion 421 through the through groove 422, and a spring 45 is sleeved around it. The spring 45 abuts against the extension portion 421.

[0029] In general, the extension 421 has a stepped groove 423 on the opposite side of the through groove 422, wherein the free end of the guide rod 44 is rotatably connected to a limiting part 46, the limiting part 46 avoids the extension 421 through the through groove 422, and is rotatably disposed in the stepped groove 423.

[0030] It is worth mentioning that a baffle is detachably connected to the other side of the housing 1 by bolts, the cylinder 43 is fixed on the baffle, and the length of the baffle is greater than that of the push plate 41, and a sealing gasket is provided between the baffle and the housing 1;

[0031] Furthermore, the brush plate 42 is slidably connected to the guide rod 44 and generates a thrust opposite to that of the push plate 41 under the elastic support of the spring 45. Because the limiting part 46 is located in the stepped groove 423, it limits and abuts the brush plate 42, preventing the brush plate 42 from detaching from the push plate 41. Of course, the limiting part 46 is also limited by the stepped groove 423 and cannot rotate.

[0032] And, press down on the brush plate 42 to disengage the limiting part 46 from the stepped groove 423, and then rotate the limiting part 46 to allow it to pass through the through groove 422 and disengage from the extension part 421, thereby disassembling the brush plate 42.

[0033] It should be noted that the stepped groove 423 needs to have sufficient depth to prevent the limiting part 46 from disengaging from the stepped groove 423 when the brush plate 42 comes into contact with the sieve plate. In other words, the brush plate 42 needs to be manually pressed to move downward to a certain position before it can be disassembled.

[0034] Finally, the housing 1 is fixedly connected to a guide plate 5 at the discharge port.

[0035] Working method: During operation, the motor drives the rotating shaft to rotate the crushing disc, and then the fish and shrimp are poured in from the feed port of shell 1 for crushing. The crushed fish and shrimp fall onto the screen plate, and the blood water enters the water collection tank through the screen holes and can be discharged through the drain pipe.

[0036] Then, the cylinder 43 drives the push plate 41 to clean the meat paste on the sieve plate, and the push plate 41 can clean the sieve holes of the sieve plate by using the brush plate 42 at the bottom while moving.

[0037] When the brush plate 42 needs to be replaced, press the brush plate 42 down to disengage the limiting part 46 from the stepped groove 423, and then rotate the limiting part 46 to allow it to pass through the through groove 422 and disengage from the extension part 421, thereby disassembling the brush plate 42.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
