Description

Technical Field

[0001] This invention relates to the field of walnut shell crushing technology, and in particular to a thin-shelled hickory shell crushing device. Background Technology

[0002] Thin-shelled pecans, as a nut with high economic value, generate a large amount of byproducts during processing—walnut shells. Walnut shells are hard and dense; directly discarding them not only wastes resources but also potentially burdens the environment. In fact, properly crushed walnut shells can be used as biomass fuel, activated carbon raw material, composite material filler, or horticultural mulch, possessing high reuse value. Therefore, efficient and controllable crushing of thin-shelled pecan shells is a key pretreatment step for realizing their resource utilization.

[0003] Existing walnut shell crushing equipment mostly uses hammer mills, blade cutters, or roller crushers. These devices have several shortcomings in practical applications: First, for materials like thin-shelled walnuts, which have a certain degree of toughness and uneven hardness, simple primary crushing often only yields coarse crushed materials of varying sizes and irregular shapes. Subsequent multi-stage processing is required to achieve the ideal particle size, making the process cumbersome and energy-intensive. Second, existing equipment easily generates a large amount of dust during the crushing process, polluting the working environment, harming the health of operators, and causing material loss. Third, many devices have constant crushing force and frequency, making it difficult to achieve efficient impact crushing of specific materials, resulting in low crushing efficiency or uneven particle size. Some devices also suffer from problems such as jamming or severe wear of crushing components. Furthermore, there is a lack of specialized devices that integrate primary and fine crushing, enabling automatic feeding, grading crushing, and dust collection.

[0004] Therefore, there is an urgent need to develop a crushing device specifically designed for the characteristics of thin-shelled pecan shells. This device should integrate preliminary crushing with multi-stage fine impact crushing. Through a rational mechanical structure design, it should effectively accumulate and release crushing force, thereby improving the crushing efficiency and uniformity of hard pecan shells. Simultaneously, it should have an effective dust collection function to improve the working environment and reduce material loss. The entire crushing process should strive for automation and continuity to improve processing efficiency, reduce labor costs, and provide reliable technical equipment support for the high-value-added resource utilization of thin-shelled pecan shells. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a thin-shelled pecan shell crushing device, comprising an external frame and a crushing mechanism for secondary crushing of the thin-shelled pecan shells after preliminary crushing. The external frame is provided with a crushing mechanism for preliminary crushing of the thin-shelled pecan shells and a drive mechanism for providing power to the device. The crushing mechanism includes an inclined crushing chamber fixedly installed on an external frame, and two fine crushing chambers, one upper and one lower, are fixedly installed inside the external frame. Each of the two fine crushing chambers has a side connecting plate slidably installed inside the two fine crushing chambers. The rolling mechanism includes a lifting toothed plate that is slidably installed inside the outer frame.

[0006] Furthermore, the crushing mechanism also includes a fine crushing hammer fixedly installed on the side connecting plate. The fine crushing hammer slides in the fine crushing chamber. Two fine crushing hammers are fixedly installed by a side inclined plate. The fine crushing hammer is provided with a slope. The fine crushing chamber is provided with a slope of the same gradient. The bottom rear end of the fine crushing chamber is provided with a discharge outlet.

[0007] Furthermore, the crushing mechanism also includes fixed blocks that are slidably installed on both sides of the fine crushing chamber. A block spring is provided between the fixed blocks and the fine crushing chamber. The upper surface of the fixed blocks is provided with a slope, and the slope is at an angle of 85° with the horizontal plane. The side connecting plate is provided with a groove that matches the fixed blocks. The groove is provided with a slope, and the slope is at an angle of 85° with the horizontal plane. The slope of the fixed blocks fits into the slope of the groove of the side connecting plate.

[0008] Furthermore, the crushing mechanism also includes a settling box fixedly installed below the inclined crushing chamber. The settling box is provided with multiple exhaust holes and air inlets. A fan bracket is fixedly installed below the inclined crushing chamber, and a dust collection fan is fixedly installed on the fan bracket. The dust collection fan is located next to the exhaust holes inside the settling box.

[0009] After initial crushing, the thin-shelled pecan shells enter the settling chamber from the inclined crushing chamber. The dust collection fan draws the dust and other particles generated during crushing into the settling chamber through the exhaust holes on the settling chamber. The pecan shells with the dust removed enter the upper fine crushing chamber, where the fine crushing hammer performs charged impact crushing on the pecan shells. The crushed pecan shells enter the lower fine crushing chamber through the discharge outlet, where the fine crushing hammer performs charged impact crushing on the pecan shells again. The crushed pecan shells fall out through the discharge outlet for collection.

[0010] Furthermore, the compaction mechanism also includes a vertical groove upright fixedly installed on the inclined compaction chamber. A vertical groove is provided on the vertical groove upright. A lifting slide column is slidably installed in the vertical groove. An outer rotating rod is rotatably installed on the lifting slide column. A lifting column body is rotatably installed on the outer rotating rod. The lifting tooth plate is fixedly installed with the lifting column body. A compression spring is provided between the lifting column body and the external frame.

[0011] Furthermore, the compaction mechanism also includes a compaction rod rotatably mounted on a lifting slide column, a compaction roller rotatably mounted on the compaction rod, the compaction roller rolling in the inclined compaction chamber, an inlet fixedly mounted on the inclined compaction chamber, and multiple discharge troughs provided at the bottom of the inclined compaction chamber.

[0012] Thin-shelled pecan shells are fed into the inlet and fall into the inclined crushing chamber. As the lifting toothed plate moves downward along the outer frame, the compression spring is compressed, driving the lifting slide column down the vertical chute via the outer rotating rod. The lifting slide column, through the crushing rotating rod, drives the crushing roller to move downward within the inclined crushing chamber. The crushing roller pushes the pecan shells that have been crushed and reached the left side of the crushing roller onto the drop-out chute. The pecan shells fall into the sinking box through the drop-out chute. When the compression spring is released, the lifting toothed plate moves upward along the outer frame, driving the lifting slide column up the vertical chute via the outer rotating rod. The lifting slide column, through the crushing rotating rod, drives the crushing roller to move upward within the inclined crushing chamber. The crushing roller crushes the pecan shells that are not yet fully crushed on the right side of the crushing roller. Pecan shells that have been crushed to a certain size slide from the gap between the crushing roller and the inclined crushing chamber above and below the crushing roller to the left side of the crushing roller.

[0013] Furthermore, the drive mechanism includes a bottom motor fixedly installed below the inclined compaction chamber, a motor gear fixedly installed on the motor shaft of the bottom motor, a toothed gear rotatably installed below the inclined compaction chamber, an outer turntable fixedly installed on the outside of the toothed gear, a bottom transmission belt wrapped around the motor gear and the outer turntable, and the toothed gear meshing with the lifting gear plate.

[0014] Furthermore, the drive mechanism also includes an eccentric rotating column fixedly mounted on the outer turntable, a pull rod rotatably mounted on the eccentric rotating column, a force storage groove provided on the pull rod, an inner sliding block slidably mounted in the force storage groove, a force storage pull rod fixedly mounted on the inner sliding block, a force storage spring provided between the inner sliding block and the eccentric rotating column, and the force storage pull rod rotatably mounted to the upper side connecting plate.

[0015] The bottom motor drives the motor gear to rotate, which in turn drives the outer turntable and the toothed gear to rotate via the bottom transmission belt. The rotation of the outer turntable causes the eccentric rotating column to rotate eccentrically. Due to the large slope angle on the fixed clamping block, the pulling rod cannot pull the side connecting plate and the precision breaker hammer to slide in the precision crushing chamber via the force storage rod. At this time, the inner sliding block slides in the force storage groove, and the force storage spring is stretched to store force. When the inner sliding block contacts the end of the force storage groove, the force storage spring is stretched to its maximum length. At this time, the force storage groove directly pulls the inner sliding block and the force storage rod to rotate, thereby causing the side connecting plate and the two precision breaker hammers to slide a short distance in the precision crushing chamber. At this time, the groove of the side connecting plate pushes the fixed clamping block downward through the slope, and the clamping block spring is compressed. After the fixed block is pulled out of the slot of the side connecting plate, the energy storage spring quickly rebounds, driving the side connecting plate and the fine crusher to rapidly accumulate energy in the fine crushing chamber to impact and crush the walnut shells inside. The crushed walnut shells in the upper fine crushing chamber enter the next fine crushing chamber through the discharge outlet, while the crushed walnut shells in the lower fine crushing chamber fall out through the discharge outlet for collection. Then, the outer turntable continues to rotate, pushing the fine crusher and the side connecting plate outward and resetting by pulling the rotating rod and the energy storage rod. When the slot of the side connecting plate reaches above the fixed block, the block spring rebounds, causing the fixed block to re-engage in the slot of the side connecting plate, ready for the next energy storage impact crushing, and so on.

[0016] When the toothed gear meshes with the lifting gear plate, the toothed gear drives the lifting gear plate to descend. At this time, the compression spring is compressed. When the toothed gear disengages from the lifting gear plate, the compression spring rebounds and resets, causing the lifting gear plate to rise, thereby realizing the reciprocating lifting of the lifting gear plate.

[0017] The beneficial effects of this invention compared with the prior art are: (1) This invention achieves the energy storage and release working cycle through the clever cooperation of the drive mechanism with the fixed block, the block spring and the energy storage spring. During the energy storage stage, the fine breaker is locked by the fixed block, and the energy of the transmission system is stored in the energy storage spring. When the energy storage reaches the limit, the fixed block is released, and the energy storage spring is released instantly, driving the fine breaker to impact at high speed and applying a strong instantaneous impact force to the material in the fine crushing chamber. This impact crushing method is more effective for hard and brittle materials than continuous crushing or shearing. Through the fine crushing chambers connected in series at the upper and lower levels, the material can be subjected to two high-intensity impact crushings in sequence, ensuring that the final output particles are finer and more uniform, meeting the particle size requirements for subsequent high-value-added utilization; (2) This invention integrates the three key processes of crushing, fine crushing and dust collection into a compact system. The material is first crushed and sized by the crushing roller in the inclined crushing chamber, which completes the effective pretreatment and creates conditions for subsequent impact crushing. Before entering the fine crushing chamber, the dust-laden airflow generated by the initial crushing is actively drawn and collected by the system consisting of the dust extraction box and the dust collection fan, and dust removal is carried out near the dust generation point, which effectively curbs the diffusion of dust in the equipment and its escape into the external environment, and significantly improves the working environment; (3) In the rolling mechanism set by the present invention, when the toothed gear disengages, the compression spring can automatically and quickly reset the lifting tooth plate and the rolling roller to the upper position, ensuring the periodic cycle of the rolling action without the risk of jamming. In the crushing mechanism, the fixed block and the side The connecting plate slot adopts an 85° large-angle slope and is clamped by a locking spring. This design not only ensures the firmness of the locking during the power storage phase, but also allows for easy unlocking by sliding the side connecting plate with a small displacement. After unlocking, when the side connecting plate is reset, the locking spring can immediately push the locking block to automatically reset and re-lock into the slot of the side connecting plate, preparing for the next power storage cycle. This ensures that the device can still work automatically, reliably, and continuously under high speed and high impact load. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0029] Example: Reference Figures 1-9 A thin-shelled pecan shell crushing device includes an outer frame 101 and a crushing mechanism for secondary crushing of the thin-shelled pecan shells after preliminary crushing. The outer frame 101 is provided with a crushing mechanism for preliminary crushing of the thin-shelled pecan shells and a drive mechanism for providing power to the device. The crushing mechanism includes an inclined crushing chamber 105 fixedly installed on an external frame 101. Two fine crushing chambers 106 are fixedly installed inside the external frame 101. Each of the two fine crushing chambers 106 has a side connecting plate 111 slidably installed inside it. The compaction mechanism includes a lifting toothed plate 208 that is slidably installed inside the external frame 101.

[0030] like Figures 2-5 As shown, the crushing mechanism also includes a fine crushing hammer 107 fixedly installed on the side connecting plate 111. The fine crushing hammer 107 slides in the fine crushing chamber 106. Two fine crushing hammers 107 are fixedly installed by the side inclined plate 108. The fine crushing hammer 107 is provided with a slope. The fine crushing chamber 106 is provided with a slope of the same gradient. The bottom rear end of the fine crushing chamber 106 is provided with a discharge outlet 112.

[0031] like Figures 2-5 As shown, the crushing mechanism also includes fixed blocks 109 that are slidably installed on both sides of the fine crushing chamber 106. A block spring 110 is provided between the fixed blocks 109 and the fine crushing chamber 106. The upper surface of the fixed blocks 109 is provided with a slope, and the angle between the slope and the horizontal plane is 85°. The side connecting plate 111 is provided with a groove that matches the fixed blocks 109. The groove is provided with a slope, and the angle between the slope and the horizontal plane is 85°. The slope of the fixed blocks 109 fits against the slope of the groove of the side connecting plate 111.

[0032] like Figures 2-5 As shown, the crushing mechanism also includes a settling box 102 fixedly installed below the inclined crushing chamber 105. The settling box 102 is provided with multiple exhaust holes and air inlets. A fan bracket 103 is fixedly installed below the inclined crushing chamber 105. A dust collection fan 104 is fixedly installed on the fan bracket 103. The dust collection fan 104 is located next to the exhaust holes inside the settling box 102.

[0033] After initial crushing, the thin-shelled pecan shells enter the settling chamber 102 from the inclined crushing chamber 105. The dust collection fan 104 draws the dust and other particles generated during crushing into the settling chamber 102 through the exhaust holes on the settling chamber 102. The pecan shells with the dust removed enter the upper fine crushing chamber 106. The fine crushing hammer 107 performs charged impact crushing on the pecan shells in the fine crushing chamber 106. The crushed pecan shells enter the lower fine crushing chamber 106 through the discharge outlet 112. The fine crushing hammer 107 performs charged impact crushing on the pecan shells in the fine crushing chamber 106 again. The crushed pecan shells fall out through the discharge outlet 112 for collection.

[0034] like Figure 6 , Figure 7 As shown, the compaction mechanism also includes a vertical groove upright 201 fixedly installed on the inclined compaction chamber 105. A vertical groove 202 is provided on the vertical groove upright 201. A lifting slide column 203 is slidably installed in the vertical groove 202. An outer rotating rod 207 is rotatably installed on the lifting slide column 203. A lifting column body 209 is rotatably installed on the outer rotating rod 207. A lifting toothed plate 208 is fixedly installed with the lifting column body 209. A compression spring 210 is provided between the lifting column body 209 and the outer frame 101.

[0035] like Figure 6 , Figure 7 As shown, the compaction mechanism also includes a compaction rod 204 rotatably mounted on the lifting slide column 203, a compaction roller 206 rotatably mounted on the compaction rod 204, the compaction roller 206 rolling in the inclined compaction chamber 105, an inlet 205 fixedly mounted on the inclined compaction chamber 105, and multiple discharge grooves 211 provided at the bottom of the inclined compaction chamber 105.

[0036] Thin-shelled pecan shells are fed into the inlet 205 and fall into the inclined crushing chamber 105. When the lifting toothed plate 208 moves downwards along the outer frame 101, the compression spring 210 is compressed, causing the lifting slide column 203 to descend along the vertical slide groove 202 via the outer rotating rod 207. The lifting slide column 203, through the crushing rotating rod 204, drives the crushing roller 206 downwards within the inclined crushing chamber 105. The crushed pecan shells that have reached the left side of the crushing roller 206 are pushed onto the discharge transverse groove 211 by the crushing roller 206. The thin-shelled pecan shells then fall into the... In the sinking box 102, when the compression spring 210 is released, the lifting toothed plate 208 moves upward along the outer frame 101, and drives the lifting slide column 203 to rise along the vertical slide groove 202 through the outer rotating rod 207. The lifting slide column 203 drives the rolling roller 206 to move upward in the inclined rolling chamber 105 through the rolling rotating rod 204. The rolling roller 206 crushes the uncrushed thin-shelled pecan shells on the right side of the rolling roller 206. The thin-shelled pecan shells crushed to a certain size will slide from the gap between the rolling roller 206 and the inclined rolling chamber 105 above and below to the left side of the rolling roller 206.

[0037] like Figure 8 , Figure 9 As shown, the drive mechanism includes a bottom motor 301 fixedly installed below the inclined compaction chamber 105. A motor gear 302 is fixedly installed on the motor shaft of the bottom motor 301. A toothed gear 304 is rotatably installed below the inclined compaction chamber 105. An outer turntable 303 is fixedly installed on the outside of the toothed gear 304. A bottom transmission belt 305 is wound around the motor gear 302 and the outer turntable 303. The toothed gear 304 meshes with the lifting gear plate 208.

[0038] like Figure 8 , Figure 9 As shown, the drive mechanism also includes an eccentric rotating column 307 eccentrically fixed on the outer turntable 303. A pull rod 306 is rotatably mounted on the eccentric rotating column 307. A power storage groove 311 is provided on the pull rod 306. An inner sliding block 309 is slidably mounted in the power storage groove 311. A power storage pull rod 308 is fixedly mounted on the inner sliding block 309. A power storage spring 310 is provided between the inner sliding block 309 and the eccentric rotating column 307. The power storage pull rod 308 is rotatably mounted to the upper side connecting plate 111.

[0039] The bottom motor 301 drives the motor gear 302 to rotate. The motor gear 302 drives the outer turntable 303 and the toothed gear 304 to rotate via the bottom transmission belt 305. The rotation of the outer turntable 303 drives the eccentric rotating column 307 to rotate eccentrically. Due to the large slope angle on the fixed block 109, the pulling rod 306 cannot pull the side connecting plate 111 and the fine breaker hammer 107 to slide in the fine crushing chamber 106 via the power storage rod 308. At this time, the inner sliding block 309 is in the power storage groove 3. When the inner sliding block 309 slides inward, the energy storage spring 310 is stretched to store energy. When the inner sliding block 309 contacts the end of the energy storage groove 311, the energy storage spring 310 is stretched to its maximum length. At this time, the energy storage groove 311 directly pulls the inner sliding block 309 and the energy storage rod 308 to rotate, thereby causing the side connecting plate 111 and the two precision breakers 107 to slide a short distance in the precision breaking chamber 106. At this time, the groove of the side connecting plate 111 pushes the fixing block 109 downward through the slope. When spring 110 is compressed, and the fixing block 109 is pulled out from the slot of the side connecting plate 111, the storage spring 310 quickly rebounds, driving the side connecting plate 111 and the fine crusher 107 to quickly store force in the fine crushing chamber 106 to impact and crush the walnut shells in the fine crushing chamber 106. The crushed walnut shells in the upper fine crushing chamber 106 enter the next fine crushing chamber 106 through the discharge outlet 112, while the lower fine crushing chamber 10... The crushed walnut shells inside the 6th section fall out through the discharge outlet 112 for collection. Then, the outer turntable 303 continues to rotate, and by pulling the rotating rod 306 and the power storage rod 308, the precision breaker hammer 107 and the side connecting plate 111 are pushed outward to reset. When the slot of the side connecting plate 111 reaches above the fixed block 109, the block spring 110 rebounds, causing the fixed block 109 to be locked back into the slot of the side connecting plate 111, ready for the next power storage impact crushing, and so on.

[0040] When the toothed gear 304 meshes with the lifting gear plate 208, the toothed gear 304 drives the lifting gear plate 208 to descend. At this time, the compression spring 210 is compressed. When the toothed gear 304 disengages from the lifting gear plate 208, the compression spring 210 rebounds and resets, causing the lifting gear plate 208 to rise, thereby realizing the reciprocating lifting of the lifting gear plate 208.

[0041] The working principle of the thin-shelled pecan shell crushing device disclosed in this invention is as follows: the bottom motor 301 drives the motor gear 302 to rotate. The motor gear 302 drives the outer turntable 303 and the toothed gear 304 to rotate through the bottom transmission belt 305. When the toothed gear 304 meshes with the lifting gear plate 208, the toothed gear 304 drives the lifting gear plate 208 to descend. At this time, the compression spring 210 is compressed. When the toothed gear 304 disengages from the lifting gear plate 208, the compression spring 210 rebounds and resets, causing the lifting gear plate 208 to rise, thereby realizing the reciprocating lifting of the lifting gear plate 208.

[0042] Thin-shelled pecan shells are fed into the inlet 205 and fall into the inclined crushing chamber 105. When the lifting toothed plate 208 moves downwards along the outer frame 101, the compression spring 210 is compressed, causing the lifting slide column 203 to descend along the vertical slide groove 202 via the outer rotating rod 207. The lifting slide column 203, through the crushing rotating rod 204, drives the crushing roller 206 downwards within the inclined crushing chamber 105. The crushed pecan shells that have reached the left side of the crushing roller 206 are pushed onto the discharge transverse groove 211 by the crushing roller 206. The thin-shelled pecan shells then fall into the... In the sinking box 102, when the compression spring 210 is released, the lifting toothed plate 208 moves upward along the outer frame 101, and drives the lifting slide column 203 to rise along the vertical slide groove 202 through the outer rotating rod 207. The lifting slide column 203 drives the rolling roller 206 to move upward in the inclined rolling chamber 105 through the rolling rotating rod 204. The rolling roller 206 crushes the uncrushed thin-shelled pecan shells on the right side of the rolling roller 206. The thin-shelled pecan shells crushed to a certain size will slide from the gap between the rolling roller 206 and the inclined rolling chamber 105 above and below to the left side of the rolling roller 206.

[0043] After initial crushing, the thin-shelled pecan shells enter the settling chamber 102 from the inclined crushing chamber 105. The dust collector 104 draws dust and other particles generated during crushing into the settling chamber 102 through the exhaust holes. The pecan shells, now free of dust, enter the upper fine crushing chamber 106. The outer turntable 303 rotates, causing the eccentric rotating column 307 to rotate eccentrically. Due to the large slope angle on the fixed clamping block 109, pulling the rotating rod 306 at this time cannot pull the side connecting plate 111 and the load-bearing pull rod 308. The precision breaker 107 slides within the precision crushing chamber 106. Simultaneously, the inner sliding block 309 slides within the energy storage groove 311, stretching the energy storage spring 310 to store energy. When the inner sliding block 309 contacts the end of the energy storage groove 311, the energy storage spring 310 is stretched to its maximum length. The energy storage groove 311 then directly pulls the inner sliding block 309 and the energy storage rod 308 to rotate, thereby causing the side connecting plate 111 and the two precision breaker 107 to slide a short distance within the precision crushing chamber 106. At this time, the side connecting plate 111... The slot pushes the fixed block 109 downward through the slope, compressing the block spring 110. When the fixed block 109 is pulled out of the slot of the side connecting plate 111, the energy storage spring 310 quickly rebounds, driving the side connecting plate 111 and the fine crusher 107 to quickly accumulate force in the fine crushing chamber 106 to impact and crush the walnut shells in the fine crushing chamber 106. The crushed walnut shells in the upper fine crushing chamber 106 enter the next fine crushing chamber 10 through the discharge outlet 112. In step 6, the crushed walnut shells in the lower fine crushing chamber 106 are collected by falling out through the discharge outlet 112. Then, the outer turntable 303 continues to rotate, and by pulling the rotating rod 306 and the power storage rod 308, the fine crusher 107 and the side connecting plate 111 are pushed outward to reset. When the slot of the side connecting plate 111 reaches above the fixed block 109, the block spring 110 rebounds, so that the fixed block 109 is locked into the slot of the side connecting plate 111 again, ready for the next power storage impact crushing, and so on.
