Description

Technical Field

[0001] This utility model relates to a composting device for Torreya grandis, and more particularly to a vibrating composting device for Torreya grandis. Background Technology

[0002] As a rare and precious dried fruit and economic tree species unique to my country, Torreya grandis has extremely high nutritional and medicinal value. After harvesting, Torreya grandis needs to undergo a post-harvest ripening and composting process to promote the transformation of the contents in the kernel, remove astringency and enhance aroma. This step often has a decisive impact on the final quality and taste of Torreya grandis. However, the post-harvest processing technology of Torreya grandis industry in China, especially the optimization of the post-harvest ripening process, has always been a technical challenge for the industry's development.

[0003] The current method of post-fermentation composting mainly relies on manual composting. This traditional method requires a lot of labor costs, and uneven turning and inconsistency are prone to occur during the composting process, which affects the quality of Torreya grandis. Currently, some torreya nut composting equipment has been developed in China. These composting devices are mainly drum composting and conveyor belt composting (publication number CN117142182A). Drum composting uses the tumbling motion of the drum to achieve the post-ripening process of torreya nuts. During composting, the torreya nuts inside will be piled together in an arc-shaped cross section, resulting in uneven composting height and easily leading to inconsistent quality. Although conveyor belt composting equipment can ensure that torreya nuts are composted on a flat surface, due to the accumulation angle when the material is piled up, the torreya nuts will also have inconsistent composting height and uneven distribution when composted on the belt. Moreover, these conveyor belt composting devices are composed of multiple independent circulation units, which can only achieve unidirectional conveying. They have a small torreya nut capacity, occupy a large space, and cannot meet the needs of large-scale composting. They are difficult to adapt to modern production models and form a strong market competitiveness. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a vibratory composting device for Torreya grandis.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A vibratory composting device for Torreya grandis includes a frame, a feeding hopper, and a hopper elevator. The hopper elevator is equipped with several hoppers. The frame is equipped with a vibratory conveying hopper assembly located on the side of the hopper elevator for receiving Torreya grandis from the hoppers. The multiple vibratory conveying hopper assemblies are arranged from top to bottom on the frame. Two adjacent vibratory conveying hopper assemblies are connected end to end. The output end of the lowest vibratory conveying hopper assembly is equipped with a discharge chute, and the discharge chute is equipped with a return chute connected to the feeding hopper.

[0006] Preferably, the vibrating hopper assembly includes a hopper, a vibrating motor, and a damping spring. The vibrating motor is mounted on the hopper, and the hopper is mounted on the frame via the damping spring. The front end of the hopper is open, and the front end of the upper hopper is connected to the rear end of the lower hopper.

[0007] As a preferred option, multiple vibrating conveying bucket assemblies are installed on both sides of the bucket elevator, and a diversion trough is installed on the top of the frame. The two ends of the diversion trough are connected to the corresponding conveying buckets. When the bucket elevator drives the bucket to flip over its top, the bucket flips and the torreya nuts inside are poured into the diversion trough.

[0008] As a preferred option, shock-absorbing springs are installed at the corners of the conveying hopper, frame hangers are provided on the frame, and grooves are provided on the conveying hopper. One end of the shock-absorbing spring is hung on the frame hanger, and the other end is hung on the groove.

[0009] Preferably, the cross-sectional shape of the hopper is "U" shaped, and several ventilation holes are provided on all surfaces of the hopper.

[0010] Preferably, the unloading chute is also equipped with a feeding chute, and the return chute is located above the feeding chute. The outer wall of the unloading chute is equipped with a guide rail. The unloading chute is installed on the frame through the guide rail. When the unloading chute is pulled out, the outlet end of the bottom conveying hopper is connected to the feeding chute; when the unloading chute is pushed forward, the outlet end of the bottom conveying hopper is connected to the return chute.

[0011] Preferably, the bucket elevator includes a lifting frame, a conveyor and a driver. The conveyor is mounted on the lifting frame via rollers, and the bucket is mounted on the conveyor. The conveyor drives the bucket into the feed bin.

[0012] Preferably, the inner side of the feeding hopper is open and installed on the lifting frame. The upper and lower ends of the feeding hopper form a feeding port and a hopper inlet, respectively. The hopper inlet is used to allow the hopper to pass through and has a number of brushes at its port.

[0013] Preferably, the feeding hopper is equipped with a hopper contact plate and a material contact plate for placing torreya nuts. The feeding hopper is provided with a first track extending from bottom to top. One end of the material contact plate is installed on the first track, and the other end is hinged to the hopper contact plate. The other end of the hopper contact plate is hinged to the feeding hopper. The hopper enters the feeding hopper and pushes open the hopper contact plate. The hopper contact plate drives the material contact plate to move along the first track.

[0014] Preferably, a second track is provided on the side plate of the feed hopper, and the material contact plate and the hopper contact plate are hinged together and mounted on the second track by a pin.

[0015] This utility model, by adopting the above technical solution, has significant technical effects: (1) The vibrating conveyor hopper assembly can make the composting of Torreya grandis more uniform and improve its quality. In the case of the cylindrical composting container, the Torreya grandis inside the drum composting equipment will be stacked together in an arc-shaped cross section during composting, resulting in uneven composting height and easy to cause inconsistent quality of Torreya grandis. Although the belt composting equipment can ensure that the composting of Torreya grandis is carried out on a flat surface, the Torreya grandis will also have inconsistent composting height and uneven distribution when the material is stacked on the belt due to the stacking angle. The vibrating conveyor hopper assembly of this utility model can make the Torreya grandis make an upward feeding and tumbling motion under the action of the oblique vibration force of the vibrating motor, so that the Torreya grandis is dispersed and evenly stacked in the conveyor hopper, thereby ensuring the consistency of Torreya grandis composting and better composting effect.

[0016] (2) The material circulation conveying layout makes the composting of Torreya grandis more thorough and enables large-scale composting. This utility model forms a complete feeding-composting-returning-feeding circulation system by combining the material circulation conveying layout with components such as the feeding hopper, hopper elevator, diversion trough, and return trough. It can realize the cyclic composting of Torreya grandis, with a high degree of automation, large composting capacity, and no need for manual intervention. By replacing manual operation with assembly line operation, it can improve the composting quality of Torreya grandis and effectively solve problems such as high labor intensity, high production cost, low efficiency, and unstable quality.

[0017] (3) The feeding hopper can effectively prevent problems such as spillage and blockage of Chinese torreya nuts during feeding. Chinese torreya nuts are generally olive-shaped or oval with grooves on the surface. After harvesting, the ungraded Chinese torreya nuts have large differences in particle size. Small particles easily fill the gaps between large particles, which increases friction. During the composting process, the surface of the Chinese torreya nuts changes from wet to dry, and the fluidity will decrease accordingly (they stick when wet and the friction increases when dry). If the hopper of the traditional belt conveyor is used to hold Chinese torreya nuts, if the hopper outlet is not designed properly, the Chinese torreya nuts may be blocked at the outlet when they are piled together, resulting in uneven feeding. In addition, there is usually a gap between the hopper and the conveyor belt of the traditional belt conveyor. Small particles of Chinese torreya nuts may fall out of the hopper or conveyor belt, requiring manual intervention and adjustment, which affects the efficiency of automation. To ensure that the hopper elevator can continuously and stably supply material to the vibrating conveyor hopper assembly, this utility model is designed with a leak-proof loading mechanism in the feed hopper. This mechanism can achieve self-adjustment. Through the linkage design of the hinged hopper contact plate and the material contact plate, the automatic opening and closing is achieved by using the gravity of the material and the hopper's pushing force. A leak-proof brush is also installed below the mechanism, which can effectively avoid problems such as spillage and blockage during the loading process. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail with reference to the embodiments. Example 1

[0025] A vibrating composting device for Torreya grandis includes a frame 1, a feeding hopper 2, and a hopper elevator 3. The feeding hopper 2 is connected to the bottom of the hopper elevator 3. Several hoppers 31 are installed on the hopper elevator 3 for holding Torreya grandis. A vibrating conveyor hopper assembly 4 is installed on the side of the hopper elevator 3 to receive Torreya grandis from the hoppers 31. The vibrating conveyor hopper assembly 4 is used for composting Torreya grandis. Multiple vibrating conveyor hopper assemblies 4 are arranged from top to bottom on the frame 1. Two adjacent vibrating conveyor hopper assemblies 4 are connected end to end. The upper layer of vibrating conveyor hopper assembly 4 vibrates the Torreya grandis inside to the lower layer of vibrating conveyor hopper assembly 4. A discharge chute 5 is installed at the output end of the lowest vibrating conveyor hopper assembly 4. The discharge chute 5 has a return chute 51 connected to the feeding hopper 2. The return chute 51 is used to send the Torreya grandis in the vibrating conveyor hopper assembly 4 back to the feeding hopper 2.

[0026] The vibrating hopper assembly 4 includes a hopper 41, a vibrating motor 42, and a damping spring 43. The damping spring 43 acts as a vibration buffer. The vibrating motor 42 is mounted on the hopper 41 at a certain angle on both sides of each hopper 41 to output vibration force, causing the torreya nuts to make a forward feeding and tumbling motion on the hopper 41. The hopper 41 is mounted on the frame 1 via the damping spring 43. The front end of the hopper 41 is open and mounted at an angle on the frame 1. The front end of the upper hopper 41 is connected to the rear end of the lower hopper 41. When the upper hopper 41 vibrates, the torreya nuts inside can be transported relatively smoothly to the inner end of the lower hopper 41.

[0027] Multiple vibrating conveyor bucket assemblies 4 are installed on both sides of the bucket elevator 3. In this embodiment, five vibrating conveyor bucket assemblies 4 are installed on each side of the bucket elevator 3. A diversion trough 6 is installed on the top of the frame 1. The two ends of the diversion trough 6 are connected to the corresponding conveyor buckets 41. When the bucket elevator 3 drives the bucket 31 to flip over its top, the bucket 31 flips and the torreya nuts inside are poured into the diversion trough 6. The diversion trough 6 is connected to the top of the bucket elevator 3 and is used to deliver the torreya nuts delivered by the bucket elevator 3 to the conveyor buckets 41 on both sides.

[0028] Each of the four corners of the conveying hopper 41 is equipped with a shock-absorbing spring 43, and each conveying hopper 41 corresponds to four shock-absorbing springs 43. The frame 1 is provided with a frame hanging ear 11, and the conveying hopper 41 is provided with a groove ear 44. One end of the shock-absorbing spring 43 is hung on the frame hanging ear 11, and the other end is hung on the groove ear 44.

[0029] The unloading chute 5 is also equipped with a discharge chute 52, which is used to send the torreya nuts to the collection box after composting. The return chute 51 is located above the discharge chute 52. The outer wall of the unloading chute 5 is equipped with a guide rail 7. The unloading chute 5 is mounted on the frame 1 through the guide rail 7. When the unloading chute 5 is pulled out, the outlet end of the bottom conveyor hopper 41 is connected to the discharge chute 52; when the unloading chute 5 is pushed forward, the outlet end of the bottom conveyor hopper 41 is connected to the return chute 51. Pushing or pulling out the unloading chute 5 allows the torreya nuts to fall from the last conveyor hopper 41 into the discharge chute 52 or the return chute 51, switching between the discharge and return operations.

[0030] The bucket elevator 3 includes an elevator frame 32, a conveyor 33, and a driver. In this embodiment, the conveyor 33 is a transmission belt; in other embodiments, the conveyor 33 can also be a conveyor chain. The conveyor 33 is mounted on the elevator frame 32 via rollers, and the buckets 31 are riveted to the conveyor 33. The conveyor 33 drives the buckets 31 into the feed hopper 2. The bucket elevator 3 drives the buckets 31 to load and transport the torreya nuts from the feed hopper 2 to its top. After the buckets 31 at the top of the bucket elevator 3 flip, they pour the torreya nuts into the diversion trough 6.

[0031] The inner side of the feeding hopper 2 is open and installed on the lifting frame 32. The upper and lower ends of the feeding hopper 2 form a feeding port 21 and a hopper inlet 22, respectively. The hopper inlet 22 is used to allow the hopper 31 to pass through, and a number of brushes 23 are provided at its port. The brushes 23 are used to support a small amount of torreya nuts that fall on them, preventing the torreya nuts from falling out of the feeding hopper 2.

[0032] The feeding hopper 2 is equipped with a hopper contact plate 24 and a material contact plate 25 for placing torreya nuts. The feeding hopper 2 is provided with a first track 26 extending from bottom to top. The first track 26 is a straight track hole. One end of the material contact plate 25 is installed on the first track 26, and the other end is hinged to the hopper contact plate 24. The other end of the hopper contact plate 24 is hinged to the feeding hopper 2. The hopper 31 enters the feeding hopper 2 and pushes open the hopper contact plate 24. The hopper contact plate 24 drives the material contact plate 25 to move along the first track 26.

[0033] The side plate of the feeding hopper 2 is provided with a second track 27, which is an arc-shaped track hole. The material contact plate 25 and the hopper contact plate 24 are hinged and installed on the second track 27 by a pin 28.

[0034] The bottom of the feeding hopper 2 is hollowed out to form the inlet 22. A brush 23 at the inlet of the feeding hopper 2 is used to prevent leakage. The brush 23 is in a self-locking state under the pressure of the Torreya grandis material and its own weight. When the hopper 31 enters the feeding hopper 2 through the inlet 22, it lifts the hopper contact plate 24. The hopper contact plate 24 then slides along the second track 27 at its hinge with the material contact plate 25. The other end of the hopper contact plate 24 slides along the first track 26. When the material contact plate 25 tilts at a certain angle, the Torreya grandis will slide off its surface into the hopper 31. After the hopper 31 separates from the hopper contact plate 24, the material contact plate 24, under the pressure of the Torreya grandis material, causes the hopper contact plate 24 to re-contact with the outer inclined surface of the hopper elevator 3, achieving closure. The brush 23 at the bottom of the feeding hopper 2 can block a small amount of Torreya grandis falling from the material contact plate 25, preventing leakage.

[0035] The entire vibrating torreya nut composting device has three stages: feeding, composting, and unloading.

[0036] During the feeding stage, workers first put the torreya nuts into the feeding hopper 2. After the device is started, the hopper elevator 3 and the vibrating conveyor bucket assembly 4 operate together. The hopper 31 on the hopper elevator 3 will enter the feeding hopper 2 from the bottom opening under the action of the conveyor belt. When the hopper 31 contacts the hopper contact plate 24 in the feeding hopper 2, it will push up the hopper contact plate 24 and drive the material contact plate 25 hinged to it to slide along the tracks on both sides of the feeding hopper 2. At this time, the material contact plate 25 tilts, and some of the torreya nuts on it will slide down its upper surface into the hopper 31. After the hopper 31 leaves, the material contact plate... Under the influence of gravity and the pressure of the remaining Torreya grandis, the contact plate 24 of the hopper 25 returns to its original position. When the hopper 31 is conveyed to the top of the back of the hopper elevator 3, the hopper 31 tilts and pours the Torreya grandis onto the diversion trough 6 on the back. The Torreya grandis slide down the diversion trough 6 into the conveying hoppers 41 on both sides of the hopper elevator 3. Under the action of the vibrating motor 42, the Torreya grandis pile will be dispersed and evenly piled up in the conveying hopper 41, and will be fed forward along the horizontal direction of the vibration of the vibrating motor 42. It is conveyed layer by layer from top to bottom between the staggered conveying hoppers 41. When the Torreya grandis is covered with the last layer, the feeding stage ends.

[0037] During the composting stage, the return chute 51 of the unloading chute 5 is located below the discharge port of the last layer of conveying hopper 41. A timer controls the start of the hopper elevator 3 and the vibrating conveying hopper assembly 4. The timer starts the device at preset intervals according to the pre-set composting time. At this time, the last layer of torreya nuts returns to the feeding hopper 2 via the return chute 51 of the unloading chute 5, and is then transported back to the next higher layer of conveying hopper 41 by the hopper elevator 3. Torreya nuts from other layers are then transported to the layer below them. Once each layer of torreya nuts has been transported, the turning operation is complete. When the turning operation is not started, the torreya nut pile will remain in the vibrating conveying hopper assembly 4 for post-fermentation. The entire device cycles through the above process according to the set number of turnings and composting time until the set duration and number of turnings are reached, at which point the composting stage ends.

[0038] During the unloading stage, the worker places the collection box below the unloading trough 52 of the last layer of conveying hoppers 41 on both sides, and pulls the unloading troughs 5 on both sides to move on the guide rail 7, so that the opening of the unloading trough 52 moves to below the outlet of the last layer of conveying hopper 41. At this time, the vibrating conveying hopper assembly 4 is started, so that each layer of torreya nuts passes through the unloading trough 52 from top to bottom and enters the collection box. After all the torreya nuts are collected, the unloading stage ends. Example 2

[0039] Example 2 is basically the same as Example 1, except that the cross-sectional shape of the conveying hopper 41 is "U" shaped, and several ventilation holes 411 are provided on all surfaces of the conveying hopper 41 for heat dissipation.
