Description

Technical Field

[0001] This utility model relates to the technical field of molluscicide production equipment, specifically a pulverizing device for camellia seed cake, a raw material for molluscicides. Background Technology

[0002] Molluscicides are a class of agents used to control or kill snails. They are widely used in agricultural production, aquaculture, public health, and other fields. They target harmful snails such as Oncomelania hupensis (intermediate host of schistosomiasis) and Pomacea canaliculata to reduce their damage to crops and aquaculture and the risk of disease transmission. By inhibiting the excessive reproduction of snails, they maintain the ecological balance of aquatic areas and play a key role, especially in the prevention and control of schistosomiasis.

[0003] Molluscicides mainly include chemical molluscicides, biological molluscicides, and plant-based molluscicides. Among them, plant-based molluscicides are made by extracting camellia saponin from camellia seed cake. They have the characteristics of high efficiency and low residue, and can be naturally degraded within 5 days. They are suitable for ecologically sensitive areas, especially for aquaculture.

[0004] Camellia seed cake, also known as tea bran cake, is the cake formed during the oil extraction process of camellia seeds. It contains a high concentration of tea saponin, a natural surfactant and biotoxin that has a strong killing effect on mollusks, some pests, fish, and frog eggs. It is an important raw material for biological molluscicides.

[0005] Camellia seed cake is relatively large and cannot be crushed by small grinding equipment. It needs to be initially crushed and then ground by a pulverizer to facilitate the subsequent extraction of tea saponins. Hammer mills, which use rotating hammers to crush the material, are the best choice for grinding camellia seed cake.

[0006] However, because camellia seed cake is rich in fiber, the texture of the pre-crushed camellia seed cake is soft. When it is fed into the crusher through the feed hopper, its softness makes it difficult to feed. However, the existing vibration feeding and rotary feeding methods are not suitable, as both have the problem of excessive feeding speed. If used in the feeding of camellia seed cake, it is easy to cause a large amount of pre-crushed camellia seed cake to accumulate rapidly in the crusher, resulting in the hammer blades not being able to fully function to crush the cake. Therefore, it is necessary to propose a technology to limit the increase of feeding speed for crushing camellia seed cake, a raw material for molluscicides. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a pulverizing device for camellia seed cake, a raw material for molluscicides, which aims to increase the feeding speed of the pulverizing device to a limited extent.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A device for crushing camellia seed cake, a raw material for molluscicides, includes a crusher. A feed hopper is connected to one side of the crusher.

The lower ends of the curved parts of the multiple swing rods are rotatably connected to the upper surface of a movable rod.

[0010] The bottom of the feed hopper is rotatably connected to a swing arm via a positioning shaft. One end of the swing arm is rotatably connected to the lower surface of the movable rod, and the other end is fixed with a connecting groove. A turntable is provided below the connecting groove, and an eccentric shaft on the turntable is movably inserted into the connecting groove.

[0011] The feed hopper is fixed with a protective cover covering the curved part, movable rod, swing arm, connecting groove and turntable. The turntable is mounted on a bearing seat fixed at the bottom of the inner wall of the protective cover. The turntable is provided with toothed grooves on its circumference. The turntable is driven by meshing with a gear through the toothed grooves. The gear is mounted on a drive motor fixed on the side of the crusher.

[0012] Preferably, the crusher is a hammer mill crusher.

[0013] Preferably, the bottom of the inner wall of the feed hopper is a slope, and the swing rod, swing arm, connecting groove and turntable are all parallel to the bottom of the inner wall of the feed hopper.

[0014] Preferably, the swing arm has two types: one that is slidably connected to the bottom of the inner wall of the feed hopper and the other that has a gap between it and the bottom of the inner wall of the feed hopper. The height of the swing arm with the gap between it and the bottom of the inner wall of the feed hopper is greater than the height of the swing arm that is slidably connected to the bottom of the inner wall of the feed hopper.

[0015] Preferably, the fixed rotating shaft and the positioning shaft are coaxially arranged and perpendicular to the bottom of the inner wall of the feed hopper, and the eccentric shaft is parallel to the positioning shaft. The upper and lower surfaces of the movable rod are parallel to the bottom of the inner wall of the feed hopper, and the part of the curved portion located outside the feed hopper is perpendicular to the movable rod and the swing arm.

[0016] Preferably, the top plate of the protective cover covers the curved portion.

[0017] Preferably, the drive motor is a geared servo motor.

[0018] Preferably, the drive motor is mounted on the outside of the protective cover and its output shaft passes through the protective cover and is connected to the gear inside.

[0019] Preferably, the eccentric shaft is rolledly connected to the inner wall of the connecting groove via a surface-mounted rolling bearing.

[0020] Preferably, a gate is vertically and movably installed on the crusher at the position corresponding to the feed hopper.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention utilizes a swing arm installed at the bottom of the inner wall of the feeding hopper to swing back and forth, promoting the feeding of pre-crushed rapeseed cake in the hopper. The drive motor is a geared servo motor, which drives the large turntable to rotate through a small gear, achieving a deceleration effect. The turntable uses an eccentric shaft, connecting groove, swing arm, and movable rod to simultaneously drive multiple vertically staggered swing arms to swing back and forth, thereby promoting feeding without excessive feeding speed. This achieves the goal of limitingly increasing the feeding speed of the camellia seed cake crushing device, which is the raw material for molluscicides. Attached Figure Description

[0030] like Figure 1-5As shown, this utility model provides a technical solution: a pulverizing device for camellia seed cake, a raw material for molluscicides, including a pulverizer 1, which is a hammer mill pulverizer. A feed hopper 2 is connected to one side of the pulverizer 1. A gate 16 is vertically and movably installed on the pulverizer 1 at the position corresponding to the feed hopper 2. Multiple swing rods 3 are arranged in parallel inside the feed hopper 2. The swing rods 3 are rotatably connected to the bottom of the inner wall of the feed hopper 2 through a fixed rotating shaft 4. The end of the swing rod 3 away from the discharge port of the feed hopper 2 is provided with a curved part 301 that bends upward and crosses the side wall of the feed hopper 2. The lower ends of the curved parts 301 of the multiple swing rods 3 are rotatably connected to the upper surface of the movable rod 5.

[0031] The bottom of the inner wall of the feed hopper 2 is a slope. The swing rod 3, swing arm 7, connecting groove 8 and turntable 9 are all parallel to the bottom of the inner wall of the feed hopper 2. The swing rod 3 has two types: one is slidably connected to the bottom of the inner wall of the feed hopper 2, and the other has a gap between it and the bottom of the inner wall of the feed hopper 2. The height of the swing rod 3 with a gap between it and the bottom of the inner wall of the feed hopper 2 is greater than the height of the swing rod 3 slidably connected to the bottom of the inner wall of the feed hopper 2.

[0032] The bottom of the feed hopper 2 is rotatably connected to a swing arm 7 via a positioning shaft 6. One end of the swing arm 7 is rotatably connected to the lower surface of the movable rod 5, and the other end is fixed with a connecting groove 8. A turntable 9 is provided below the connecting groove 8. An eccentric shaft 10 provided on the turntable 9 is movably inserted into the connecting groove 8. The eccentric shaft 10 is rotatably connected to the inner wall of the connecting groove 8 via a surface-mounted rolling bearing 15.

[0033] The fixed rotating shaft 4 and the positioning shaft 6 are coaxially arranged and perpendicular to the bottom of the inner wall of the feed hopper 2, and the eccentric shaft 10 is parallel to the positioning shaft 6. The upper and lower surfaces of the movable rod 5 are parallel to the bottom of the inner wall of the feed hopper 2, and the part of the bent part 301 located outside the feed hopper 2 is perpendicular to the movable rod 5 and the swing arm 7.

[0034] A protective cover 11 is fixed on the feed hopper 2, covering the outside of the curved part 301, the movable rod 5, the swing arm 7, the connecting groove 8 and the turntable 9. The top plate 1101 of the protective cover 11 covers the curved part 301. The turntable 9 is mounted on the bearing seat 12 fixed at the bottom of the inner wall of the protective cover 11. The circumference of the turntable 9 is provided with tooth grooves 901. The turntable 9 is driven by the gear 13 through the tooth grooves 901.

[0035] Working principle:

[0036] Camellia seed cake is initially crushed into small pieces and fed into hopper 2. The gate 16 is positioned and fixed according to the feeding speed. The drive motor 14 drives the gear 13, which has a diameter smaller than that of the turntable 9, to rotate. The gear 13 drives the connecting groove 8 and the swing arm 7 to swing back and forth around the positioning shaft 6 via the eccentric shaft 10 on the turntable 9. This causes the movable rod 5 to move back and forth. The movable rod 5 drives multiple swing arms 3 with different heights to swing back and forth, thereby promoting the feeding of camellia seed cake into hopper 2. The design of the geared motor, the small gear 13 driving the large turntable 9, and the eccentric shaft 10 driving the connecting groove 8 all achieve a speed reduction effect, avoiding the raw material from arching and bridging and being unable to be fed. It also avoids the feeding speed being too fast and affecting the crushing effect, thus achieving the purpose of increasing the feeding speed to a limited extent.
