Description

Technical Field

[0001] This invention belongs to the technical field of durian shell processing, specifically a durian shell processing equipment. Background Technology

[0002] This durian shell processing equipment is a durian shell crushing and processing device, specifically designed for the efficient processing of hard durian shells. It typically uses high-strength alloy blades or hammers, driven by a motor, to powerfully crush, tear, and pulverize the durian shell, rapidly transforming the entire shell into fine, uniform particles or fibrous materials. The output is suitable for subsequent composting, biomass fuel production, or extraction of high-value components, effectively solving the recycling challenges of large volume, tough texture, and difficult degradation of durian shells, thus achieving waste reduction and resource utilization.

[0003] Patent document CN222219811U describes a pulverizer for fresh durian shells, belonging to the field of pulverizer technology. It includes a housing, a first electric telescopic rod fixedly installed on the top of the housing, feeding ports on both sides of the housing, a pressing device at the top of the interior of the housing, a metal grid fixedly installed inside the housing, a pulverizing chamber slidably connected inside the housing, a motor fixedly installed at one end of the pulverizing chamber, limiting devices on both sides of the housing, and a discharge box fixedly installed at the bottom of the housing.

[0004] Existing durian shell crushers have certain shortcomings in use. When processing durian shells, these crushers also crush the sharp structures of the shells. The hard and wear-resistant physical properties of the sharps will severely wear down the blades, screens, and inner lining, significantly shortening the service life of the core components and increasing maintenance costs. Secondly, during the crushing process, the sharps and tough fibers are difficult to crush simultaneously, which easily leads to severely uneven particle size in the finished product. The external hard thorn fragments are mixed with the internal fiber powder, which seriously affects the consistency and quality of subsequent processing. It is impossible to complete the removal of sharps simultaneously before crushing. Summary of the Invention

[0005] This invention provides a durian shell processing device that solves the problems in existing technologies where the hard and wear-resistant physical properties of durian spurs cause severe wear on the cutting tools, screens, and inner lining structure, significantly shortening the service life of core components and increasing maintenance costs. Furthermore, during the crushing process, the spurs and tough fibers are difficult to break simultaneously, easily leading to severely uneven particle size in the finished product, with external hard spur fragments mixed with internal fiber powder, seriously affecting the consistency and quality of subsequent processing. A durian shell processing device includes a crushing bin and a conveying assembly. The conveying assembly is fixedly installed on one outer surface of the crushing bin. A thorn cutter for removing the sharp points of the durian peel is fixedly installed on the upper part of the conveying assembly on one outer surface of the crushing bin. The thorn cutter includes a blade and a lifting plate. The blade is movably installed on the lower part of the lifting plate. The lifting plate and the blade are movably connected by a sliding plate. One outer surface of the blade has a toothed structure. A lifting frame is movably installed on the upper end of the lifting plate.

[0006] As a further technical solution of the present invention, a vertical push rod is provided at the middle position of the upper outer surface of the lifting frame. The lifting frame and the crushing box are driven by the vertical push rod. During operation, when the durian peel is moving, the contact between the blade and the spikes causes the blade to remove the spikes of the durian peel. The lifting frame is driven by the vertical push rod, causing the lifting frame to move the blade up and down. The crushing box is equipped with an infrared sensor that can measure the thickness of the durian peel and adjust the operating height of the blade according to the thickness of the durian peel.

[0007] As a further technical solution of the present invention, the inner side of the lifting frame is provided with several sets of spring rods for use with the lifting plate. The lifting frame and the lifting plate are elastically connected by the spring rods. By using the spring rods, the lifting plate and the lifting frame have an elastic structure. When the blade contacts the manganese steel spring, the blade can be made to stick tightly to the surface of the manganese steel spring. With the height adjustment of the blade, the cleaning effect of durian thorns is improved.

[0008] As a further technical solution of the present invention, the blade and the slide are movably connected by a slide groove. One end of the slide is fixedly equipped with a motor for driving the blade. During operation, the motor drives the crank to make a circular motion, which is connected to the slider with the blade through a connecting rod, so that the slider drives the blade and makes the blade reciprocate at the bottom of the slide.

[0009] As a further technical solution of the present invention, the feeding assembly includes a feeding hopper and a discharging pipe. The feeding hopper is fixedly installed on the upper outer surface of the discharging pipe. The feeding hopper is located on one side of the crushing box. The feeding hopper can be used to transport durian peels, so that the durian peels pass through the blades for thorn removal. The removed durian thorns are discharged downward through the discharging pipe.

[0010] As a further technical solution of the present invention, the surface of the feeding hopper is provided with a discharge groove through the upper part of the discharge pipe. The discharge groove is located at the lower part of the blade. During operation, the durian thorns cut by the blade fall downwards into the discharge groove and are discharged into the discharge pipe through the discharge groove.

[0011] As a further technical solution of the present invention, upper conveying rollers are movably installed on both sides of the material discharge chute on the inner side of the feeding hopper, and lower conveying rollers are movably installed on the lower part of the upper conveying rollers, so as to transport durian peels by rotating the upper and lower conveying rollers.

[0012] As a further technical solution of the present invention, the upper conveying roller and the feeding hopper are driven by a motor and gears. A sponge tube is sleeved on the outer surface of the upper conveying roller. The sponge tube is a sleeve-shaped sponge structure. When the durian peel is conveyed, the durian thorns are inserted into the sponge tube of the upper conveying roller, which increases the friction during the conveying of durian peel and can also cope with the conveying operation of durian peel in the state of thorns.

[0013] As a further technical solution of the present invention, a pressure plate is fixedly installed on the inner side of the feeding hopper on one side of a set of upper feeding rollers. Several sets of manganese steel springs are inclinedly arranged at the bottom of the pressure plate. When the durian peel passes between a set of upper feeding rollers and lower feeding rollers, the arrangement of several sets of manganese steel springs allows the durian thorns to pass through the manganese steel springs. The manganese steel springs apply downward pressure to the durian peel. With the downward movement of the blade, the blade is placed on the upper surface of the manganese steel springs to cut off the durian thorns. The manganese steel springs play an auxiliary role in fixing the durian peel during the cutting process.

[0014] As a further technical solution of the present invention, a second hopper is fixedly installed at the lower end of the discharge pipe, a crusher is provided inside the crushing box, and a first hopper is fixedly installed on the outer surface of the crushing box. The durian peel after the thorns are removed falls into the interior of the crushing box, and the crusher is used to crush the durian peel. The crushed durian peel falls into the first hopper for collection, while the second hopper is used to collect the durian thorns discharged from the discharge pipe.

[0015] The beneficial effects of this invention are as follows: By incorporating a thorn-cutting device, this invention provides a pre-treatment structure for durian thorns in the durian shell processing equipment. This allows for the pre-cleaning of durian thorns during the durian peel crushing process, significantly reducing wear on core components and extending blade life. This directly reduces equipment maintenance frequency and replacement costs. Furthermore, the efficiency and energy consumption of the crushing process are significantly optimized. By removing the hardest and most energy-consuming thorns, the equipment achieves a more uniform and finer crushing effect with lower energy consumption, resulting in high particle size consistency. This provides higher-quality raw materials for downstream resource utilization. Whether used for producing organic fertilizer, preparing environmentally friendly fiber materials, or extracting bioactive components, a more stable and controllable processing foundation can be obtained, thereby improving the final product. In terms of quality and added value, during operation, the blades remove the thorns from the durian peel through contact with the thorns as the peel moves. A vertical push rod drives the lifting frame, which in turn moves the blades up and down. An infrared sensor inside the crushing bin measures the thickness of the durian peel and adjusts the blade height accordingly. A spring rod creates an elastic structure between the lifting plate and the lifting frame, allowing the blades to adhere tightly to the surface of the manganese steel spring when they come into contact with it. Combined with the blade height adjustment, this enhances the cleaning effect on the durian thorns. A motor drives a crank in a circular motion, which is connected to a slider containing the blades via a connecting rod. This causes the slider to drive the blades, making them reciprocate at the bottom of the slide plate. As the durian peel moves, the thorns are removed. By optimizing the use of the thorn cutter in this durian shell processing equipment through the feeding assembly, directional conveying of durian peels with thorns can be achieved. Simultaneously, the thorn-cutting operation helps to fix the durian peel, improving the thorn removal effect. During operation, the sponge tube, a sleeve-shaped sponge structure, is fitted onto the outer surface of the upper feeding roller. During durian peel conveying, the durian thorns insert into the sponge tube of the upper feeding roller, increasing friction during conveying and handling the thorny state of the durian peel. When the durian peel passes between a set of upper and lower feeding rollers, several sets of manganese steel springs are used to allow the durian thorns to pass through them. The manganese steel springs apply downward pressure to the durian peel, and the downward movement of the blade positions it on the upper surface of the manganese steel springs to cut the durian thorns. The manganese steel springs also provide auxiliary fixation for the durian peel during the cutting process. Attached Figure Description

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-4 As shown, a durian shell processing device includes a crushing bin 1 and a conveying assembly 4. The conveying assembly 4 is fixedly installed on one outer surface of the crushing bin 1. A thorn cutter 6 for removing the sharp points of the durian peel is fixedly installed on the upper part of the conveying assembly 4 on one outer surface of the crushing bin 1. The thorn cutter 6 includes a blade 13 and a lifting plate 12. The blade 13 is movably installed on the lower part of the lifting plate 12. The lifting plate 12 and the blade 13 are movably connected by a sliding plate 14. One outer surface of the blade 13 has a toothed structure. A lifting frame 8 is movably installed on the upper end of the lifting plate 12. A protective cover is provided on the outside of the blade 13 to prevent users from accidentally touching the blade 13 and improve its safety.

[0021] A vertical push rod 9 is installed at the middle of the upper outer surface of the lifting frame 8. The lifting frame 8 and the crushing box 1 are driven by the vertical push rod 9. During operation, as the durian peel moves, the contact between the blade 13 and the spikes removes the spikes from the durian peel. The vertical push rod 9 drives the lifting frame 8, causing the blade 13 to move up and down. The crushing box 1 is equipped with an infrared sensor and a CCD camera. The CCD camera can perform image recognition on the durian peel and measure its thickness. The height of the blade 13 can be adjusted according to the thickness of the durian peel. The durian peel is divided into three layers: the outer layer is the spiked part, the middle layer is the shell part, and the inner layer is the pulp part. The CCD camera identifies the position of the inner pulp part. By adjusting the height of the blade 13 accordingly, the outer spiked part and the middle shell part can be removed, leaving only the inner pulp part for later processing.

[0022] The inner side of the lifting frame 8 is provided with several sets of spring rods 10 that work with the lifting plate 12. The lifting frame 8 and the lifting plate 12 are elastically connected by the spring rods 10. The spring rods 10 provide an elastic structure between the lifting plate 12 and the lifting frame 8. When the blade 13 contacts the manganese steel spring 20, the blade 13 can be pressed tightly against the surface of the manganese steel spring 20. With the height adjustment of the blade 13, the cleaning effect on durian thorns is improved.

[0023] The blade 13 and the slide plate 14 are connected by a sliding groove. One end of the slide plate 14 is fixedly equipped with a motor 11 for driving the blade 13. During operation, the motor 11 drives the crank to make a circular motion, which is connected to the slider with the blade 13 through a connecting rod, so that the slider drives the blade 13, causing the blade 13 to move back and forth at the bottom of the slide plate 14.

[0024] The feeding assembly 4 includes a feeding hopper 15 and a discharge pipe 19. The feeding hopper 15 is fixedly installed on the upper outer surface of the discharge pipe 19. The feeding hopper 15 is located on one side of the crushing box 1. The feeding hopper 15 can be used to transport the durian peel, so that the durian peel passes through the blade 13 for thorn removal. The removed durian thorns are discharged downward through the discharge pipe 19.

[0025] The surface of the feed hopper 15 is provided with a discharge chute 16 extending through the upper part of the discharge pipe 19. The discharge chute 16 is located below the blade 13. During operation, the durian thorns cut by the blade 13 fall downwards into the discharge chute 16 and are discharged into the discharge pipe 19 through the discharge chute 16.

[0026] The inner side of the feed hopper 15 is movably equipped with upper feeding rollers 18 on both sides of the discharge chute 16. The lower feeding rollers 5 are movably installed on the lower part of the upper feeding rollers 18. The durian peel is moved by the rotation of the upper feeding rollers 18 and the lower feeding rollers 5. During the conveying, one set of upper feeding rollers 18 and lower feeding rollers 5 clamps the front end of the durian peel, and the other set of upper feeding rollers 18 and lower feeding rollers 5 clamps the rear end of the durian peel. The conveying operation of the durian peel is completed by the rotation of the two sets of upper feeding rollers 18 and lower feeding rollers 5. At the same time, the bent durian peel can be flattened by the rolling action of the upper feeding rollers 18. The setting of the two sets of upper feeding rollers 18 prevents the durian peel from bending and rebounding.

[0027] The upper conveying roller 18 and the feed hopper 15 are driven by a motor and gears. The outer surface of the upper conveying roller 18 is fitted with a sponge tube. The sponge tube is a sleeve-shaped sponge structure. When the durian peel is conveyed, the durian thorns are inserted into the sponge tube of the upper conveying roller 18, which increases the friction during the conveying of durian peel and can also cope with the conveying operation of durian peel in the state of thorns.

[0028] A pressure plate 17 is fixedly installed on the inner side of the feed hopper 15 on one side of a set of upper conveying rollers 18. Several sets of manganese steel springs 20 are inclinedly arranged at the bottom of the pressure plate 17. When the durian peel passes between a set of upper conveying rollers 18 and lower conveying rollers 5, the manganese steel springs 20 are arranged to allow the durian thorns to pass through the manganese steel springs 20. The manganese steel springs 20 apply downward pressure to the durian peel. With the downward movement of the blade 13, the blade 13 is placed on the upper surface of the manganese steel springs 20 to cut off the durian thorns. The manganese steel springs 20 play an auxiliary role in fixing the durian peel during the cutting process.

[0029] A second hopper 3 is fixedly installed at the lower end of the discharge pipe 19. A crusher 7 is installed inside the crushing box 1. A first hopper 2 is fixedly installed on the outer surface of the crushing box 1. The durian peel after the thorns are removed falls into the crushing box 1. The crusher 7 is used to crush the durian peel. The crushed durian peel falls into the first hopper 2 for collection. The second hopper 3 is used to collect the durian thorns discharged from the discharge pipe 19.

[0030] A durian shell processing device, during operation, utilizes the contact between blade 13 and the spikes during the movement of the durian peel to remove the spikes. A vertical push rod 9 drives a lifting frame 8, which in turn moves the blade 13 up and down. An infrared sensor is installed inside the crushing bin 1 to measure the thickness of the durian peel and adjust the working height of the blade 13 according to the thickness. The spring rod 10 provides an elastic structure between the lifting plate 12 and the lifting frame 8. When the blade 13 contacts the manganese steel spring 20, it can be pressed tightly against the surface of the manganese steel spring 20. Combined with the height adjustment of the blade 13, the cleaning effect of the durian spikes is improved. The motor 11 drives the crank to make a circular motion, which is connected to the slider with the blade 13 through a connecting rod. The slider drives the blade 13, causing the blade 13 to move back and forth at the bottom of the slide plate 14. The spikes are removed while the durian peel is moving. The sponge tube is a sleeve-shaped sponge structure, which is sleeved on the outer surface of the upper conveying roller 18. During the durian peel conveying operation, the durian thorns are inserted into the sponge tube of the upper conveying roller 18, which increases the friction during durian peel conveying and can also cope with the conveying operation of durian peel in the state of thorns. When the durian peel passes between a set of upper conveying rollers 18 and lower conveying rollers 5, the durian thorns are made to pass through the manganese steel springs 20 by the setting of several sets of manganese steel springs 20, and the manganese steel springs 20 apply downward pressure to the durian peel. With the downward movement of the blade 13, the blade 13 is placed on the upper surface of the manganese steel springs 20 to cut off the durian thorns. The manganese steel springs 20 play an auxiliary role in fixing the durian peel during the cutting process.
