Description

Technical Field

[0001] The utility model belongs to the technical field of shelling machines, and particularly relates to a torreya grandis shelling machine. Background Art

[0002] Torreya grandis is a perennial evergreen tree of the genus Torreya in the family Taxaceae, and it is also a unique tree species in China and a rare economic tree species in the world. The fruits of torreya grandis are rich in nutrition, have a mellow flavor, and have high economic value. Its seeds contain essential oils with more than 20 aromatic components, which are natural high-quality raw materials for high-grade aromatic oils and extracts. In addition, the essential oils of torreya grandis are also used in the daily chemical industry, such as toothpaste, soap, etc. In terms of medicine, the kernels and branches of torreya grandis can expel worms, eliminate indigestion, moisten dryness, etc., and are commonly used to treat abdominal pain caused by parasitic diseases, infantile malnutrition, dry cough, dry cough, constipation, and hemorrhoids. At the same time, the wood of torreya grandis is light, dense, and has straight texture, making it an excellent material for construction, shipbuilding, and handicraft carving.

[0003] In the processing of torreya grandis, it is necessary to shell the torreya grandis for subsequent processing. At present, most of the shelling of torreya grandis is manually completed with the help of tools. Generally, tools such as pliers are used to clamp the fruit shell of torreya grandis and break its outer shell. However, the manual shelling of torreya grandis has a large labor intensity, resulting in high labor costs and low work efficiency, which is not conducive to the large-scale production and processing of torreya grandis. Summary of the Invention

[0004] The purpose of the utility model is to provide a technical solution for a torreya grandis shelling machine aiming at the deficiencies of the existing technology. The design is ingenious and reasonable. Using this shelling machine can realize the mechanized shelling treatment of torreya grandis, reduce the manual labor intensity, effectively improve the work efficiency, reduce the labor cost, and is also more conducive to the large-scale mechanized production and processing of torreya grandis.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A torreya grandis shelling machine includes a frame, a driving mechanism, a feeding hopper, a feeding roller, a blanking frame, and a shelling mechanism. The driving mechanism is arranged on the frame. The driving mechanism includes a driving motor, a crankshaft, and a transmission component. The driving motor is connected to the crankshaft, and the crankshaft is connected to the transmission component. The feeding hopper is arranged on the frame. The feeding roller is arranged at the outlet of the feeding hopper. The feeding roller is provided with a feeding groove group. The feeding roller is connected to the transmission component. The blanking frame is connected to the transmission component. The driving motor drives the synchronous rotation of the blanking frame and the feeding roller through the transmission component. A collection box is arranged below the blanking frame, and the shelled torreya grandis is collected through the collection box. The shelling mechanism is arranged above the blanking frame. The shelling mechanism is connected to the crankshaft. The driving motor drives the shelling mechanism to move up and down through the crankshaft. The reciprocating movement of the crankshaft drives the shelling mechanism to move up and down, thereby realizing the precise downward pressing and shelling of torreya grandis.

[0007] The feeding hopper conveys torreya grandis to the feeding trough group of the feeding roller. The driving motor drives the feeding roller to roll through the transmission component to convey torreya grandis into the blanking rack. At the same time, the driving motor drives the cracking mechanism to move through the crankshaft to press down and crack the torreya grandis in the blanking rack. The cracked torreya grandis rolls into the collection box below through the rolling of the blanking rack for collection. The overall design is ingenious and reasonable. The driving motor provides power and transmits the power to each component that needs to move through the crankshaft and the transmission component. By starting the driving motor, the rotation of the feeding roller and the blanking rack and the up-and-down movement of the cracking mechanism can be realized. The feeding hopper conveys the torreya grandis to be cracked onto the feeding roller, and the orderly conveying and movement of torreya grandis are realized through the feeding trough group on the feeding roller. The blanking rack receives the torreya grandis conveyed by the feeding roller, and the torreya grandis on the blanking rack is effectively cracked through the up-and-down movement of the cracking mechanism. The cracked torreya grandis rolls along with the blanking rack, so that the cracked torreya grandis gradually rolls into the collection box below for collection for subsequent processing. The automatic feeding, cracking and collection process of torreya grandis is realized through this equipment, which greatly improves the production efficiency, reduces the labor cost, and the overall operation is simple.

[0008] Furthermore, several feeding trough groups are evenly distributed circumferentially along the outer side of the feeding roller. Each group of feeding trough groups includes at least two feeding troughs, and the feeding troughs in the same group are evenly distributed along the axial direction of the feeding cylinder. The design is ingenious. The circumferentially uniform distribution design of several feeding trough groups enables torreya grandis to be evenly distributed in each feeding trough group during the feeding process, ensuring the uniformity and continuity of feeding. And each group of feeding trough groups includes at least two feeding troughs, which can ensure the feeding capacity, enabling more torreya grandis to be conveyed each time it rotates. When designing the size of the feeding trough, it is preferably designed to be larger than the size of a single torreya grandis but smaller than the size of two torreya grandis to ensure that torreya grandis can smoothly enter and leave the feeding trough, and only one torreya grandis can be accommodated in each feeding trough, effectively ensuring the orderly conveying of torreya grandis.

[0009] Furthermore, a guiding rack is inclined between the feeding roller and the blanking rack. The guiding rack is inclined downward from the feeding roller towards the blanking rack direction. The guiding rack is fixedly connected to the machine frame. Several guiding troughs are arranged on the guiding rack. The guiding troughs are in one-to-one correspondence and matching with the feeding troughs in each group of feeding trough groups. The guiding rack can effectively connect the feeding roller and the blanking rack to ensure that torreya grandis can be smoothly transmitted from the feeding roller to the blanking rack. The inclined design of the guiding rack is more conducive to the smooth sliding of torreya grandis, and the guiding troughs can be in one-to-one correspondence with the feeding troughs in each group of feeding trough groups to ensure that torreya grandis can accurately align with the corresponding guiding troughs when entering the guiding rack from the feeding roller, avoiding misalignment or dropping of torreya grandis during the transmission process, improving the continuity of the entire production process, and ensuring the accuracy and efficiency of the subsequent cracking process.

[0010] Furthermore, the blanking rack includes a main shaft and a blanking chute. The main shaft is connected to the transmission component, and the blanking chute is fixed to the main shaft with screws. The screw fixation ensures the installation firmness and reliability between the blanking chute and the main shaft, and also facilitates the subsequent cleaning, maintenance, repair, and replacement of the blanking chute. A number of blanking chutes are evenly distributed circumferentially along the outer sidewall of the main shaft. The number of blanking chutes matches the number of feeding chute groups, enabling torreya grandis to be accurately transferred from the feeding chute to the blanking chute, improving the transfer efficiency. The two sides of the blanking chute are inclined and converged towards its center, making the cross-section of the blanking chute in a trapezoidal structure. The trapezoidal design helps in the concentration and guidance of torreya grandis during blanking, positions the torreya grandis on both sides when it is under pressure, avoids the sliding of torreya grandis, thus ensuring that the pressing head can be directly opposite the center of the torreya grandis, ensuring stability during pressing and guaranteeing the shell-breaking effect of torreya grandis. The blanking chute and the feeding chute group are preferably designed to be 12, and intermittent transmission is achieved through the transmission component. Specifically, when the crankshaft rotates one circle, the blanking rack and the feeding roller rotate one-twelfth of a circle. By controlling the transmission ratio between the crankshaft and the main shaft, it is ensured that the crankshaft presses over one blanking chute every time it rotates one circle.

[0011] Furthermore, a screening rack is provided between the blanking rack and the collection box. The screening rack is fixedly connected to the machine frame. The screening rack includes a top plate, a bottom plate, and side plates. The side plates are connected between the side ends of the top plate and the bottom plate. The bottom end of the top plate is fixedly connected to the top end of the side plate. A screening cavity with one end open is formed between the top plate, the bottom plate, and the side plates. Screening slot holes communicating with the screening cavity are provided on the top plate. The bottom plate is inclined downward towards the opening direction of the screening cavity, and the top plate is inclined downward towards the direction away from the opening of the screening cavity. A side baffle is provided above the opening of the screening cavity. The side baffle can play a certain role in blocking and intercepting, enabling the screened debris to slide out from the lower part of the opening of the screening cavity, avoiding the splashing of debris everywhere. The screening rack can screen a part of the debris generated by the shell-breaking of torreya grandis. Through preliminary screening, it facilitates subsequent processing. The inclined design of the bottom plate can facilitate the screened debris to smoothly slide into the screening cavity from the screening slot holes and then slide out smoothly towards the opening direction, avoiding the accumulation of debris on the bottom plate. The inclined design of the top plate can facilitate the shelled torreya grandis to smoothly slide into the collection box for collection, avoiding the accumulation of torreya grandis on the top plate, realizing the effective screening sequence and smooth collection of torreya grandis.

[0012] Furthermore, the transmission assembly includes cam 1, cam 2, gear 1, gear 2, gear 3, gear 4, gear 5 and gear 6. Cam 1 is arranged on the crankshaft. Cam 1 is provided with a lever column. Cam 2 and gear 1 are coaxially arranged on the frame. Cam 2 is provided with a toggle groove. There are four toggle grooves. The four toggle grooves are evenly distributed circumferentially. The lever column matches the toggle groove. When cam 1 rotates, the lever column will gradually snap into the corresponding toggle groove to drive cam 2 to rotate synchronously.

Gear 5 is meshed with gear Gear six is ​​meshed, and gear six is ​​connected to the feed roller. When the crankshaft rotates, it will drive cam one to rotate. Cam one drives cam two to rotate synchronously through the lever column and the toggle groove, thereby driving gear one to rotate. Gear one transmits the motion to gear two and gear three through meshing, and gear three transmits it to gear four. Gear four drives the blanking rack to rotate and also transmits the motion to gear five through meshing. Gear five transmits the motion to gear six, thereby driving the feed roller to rotate for feeding, thereby realizing the synchronous rotation adjustment of the feed roller and the blanking rack.

[0014] Furthermore, the crank includes an upper handle portion and a lower handle portion. The upper handle portion and the lower handle portion are fixedly connected by bolts. The bolt fixation ensures the overall structural strength of the assembled crank. A snap ring groove is formed between the upper handle portion and the lower handle portion. A limiting ring groove is provided on the crankshaft. The limiting ring groove and the snap ring groove are correspondingly matched one by one. The crank is limited and clamped in the limiting ring groove through the snap ring groove. The crank is limited in the corresponding limiting ring groove, and the crank can rotate around the limiting ring groove. The design is ingenious, which can realize the precise installation and positioning between the crank and the crankshaft, facilitate the actual assembly and disassembly, and the lateral displacement of the crank on the crankshaft can be restricted through the limiting ring groove, ensuring the stability and reliability of the crank during swinging, thus guaranteeing the stability of the entire motion transmission. Moreover, the crank is divided into two parts, namely the upper handle portion and the lower handle portion, which facilitates the installation and disassembly of the crank on the crankshaft and also facilitates the regular maintenance and replacement of the crank.

[0015] Furthermore, guide columns are provided on the punch mounting bracket. The guide columns and the guide through holes are correspondingly matched one by one. The top end of the guide column is hinged to the crank. A clamping chute is provided on the punch. A clamping slider is provided on the punch mounting bracket.

Under the compression force of the compression spring, the pressure plate contacts the limit portion, so that the push rod cannot escape from the open end, thereby ensuring the continuity and safety of the shell breaking operation. When the push rod needs to be removed, the pressure plate must be removed first before the push rod can be removed from the cavity. The guide column cooperates with the guide perforation to realize the sliding penetration setting of the pressure head mounting frame and the guide frame. The guide frame guides the limit pressure head mounting frame, so that the pressure head mounting frame drives the pressure head fixed with it to be limited and can only Vertical movement reduces deviation and shaking, thereby improving the accuracy and stability of shell breaking. The structure of the pressure head mounting frame is specifically designed. The design of the cavity in the guide column and the compression spring therein provides an automatic resetting function for the push rod. After the pressure head completes the shell breaking action, the compression force of the compression spring will push the push rod and the pressure head back to the initial position for the next shell breaking operation. At the same time, the compression spring in this design can also play a certain buffering role, which can reduce the impact force and vibration generated during shell breaking and protect the stability and service life of the entire equipment during operation.
