[0002] Amomum tsao-ko, the dried, mature fruit of the Amomum tsao-ko plant (family Zingiberaceae), is commonly used as a traditional Chinese medicine ingredient or a culinary seasoning, belonging to the category of food and medicine of the same origin. In the processing of amomum tsao-ko, the mature fresh fruit needs to be harvested and dehydrated to form a dried product before it can be stored and used. The fruit usually has a stalk, which can easily affect the edibility, storage, and transportation of the fruit. Therefore, the stalk needs to be separated from the fruit during processing. Current technology mainly relies on manual removal of the stalk, and there is no automated stalk removal equipment. The existing technology suffers from low stalk separation efficiency and high labor costs. Utility Model Content

[0003] The purpose of this invention is to solve the problems of low efficiency and high labor cost in separating hay fruit stems in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic destemming device for hawthorn fruit includes a frame, a motor mounted on the frame and electrically connected to an external power source, a transmission assembly on the output shaft of the motor, a first sieve cylinder mounted on the frame with a plurality of mesh holes, the first sieve cylinder being connected to the output shaft of the motor via the transmission assembly, a spiral blade inside the first sieve cylinder, and a scraper assembly inside the frame, the scraper assembly abutting against the first sieve cylinder.

[0006] Preferably, the frame also includes a second screen cylinder, which also has spiral blades and several mesh openings. Another scraper assembly is also provided within the frame, abutting against the second screen cylinder. The second screen cylinder is located below the first screen cylinder. A connecting pipe is provided on the frame, connecting the discharge end of the first screen cylinder to the feed end of the second screen cylinder. A first bearing and a second bearing are provided on the connecting pipe. The first bearing connects the first screen cylinder to the connecting pipe, and the second bearing connects the second screen cylinder to the connecting pipe. The transmission assembly connects the first screen cylinder to the second screen cylinder.

[0007] Preferably, the transmission assembly includes a first transmission wheel and a second transmission wheel. The first transmission wheel is connected to the output shaft of the motor, the second transmission wheel is connected to the first screen cylinder, a first transmission belt is provided between the second transmission wheel and the first transmission wheel, a third transmission wheel is also provided on the first screen cylinder, a fourth transmission wheel is provided on the second screen cylinder, and a second transmission belt is provided between the fourth transmission wheel and the third transmission wheel.

[0008] Preferably, the scraper assembly includes a blade holder, on which a first scraper and a second scraper are provided, the first scraper abutting against the first screen cylinder, and the second scraper abutting against the second screen cylinder.

[0009] Preferably, both the first scraper and the second scraper are slidably connected to the blade holder, and a locking device is provided between the first scraper and the second scraper and the blade holder.

[0012] The beneficial effects proposed by this utility model are as follows:

[0013] Workers add the dried cardamom into the first sieve cylinder through the feed end. Then, the motor is started, and its output shaft rotates, driving the first sieve cylinder to rotate via the transmission assembly. The rotation of the first sieve cylinder generates centrifugal force, causing the cardamom to adhere tightly to the cylinder wall. As the first sieve cylinder continues to rotate, the cardamom stalks pass through the mesh and are placed outside the cylinder. Subsequently, when the stalks pass through the scraper assembly, the scraper assembly separates the exposed stalks from the cardamom. Simultaneously, the first sieve cylinder is equipped with spiral blades that drive the cardamom from the feed end to the discharge end, achieving automatic feeding of the destemmed cardamom. During this movement, the stroke increases the probability of the cardamom stalks passing through the mesh, improving the destemming efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1 to 4An automatic destemming device for hawthorn fruit includes a frame 1, a motor 2 mounted on the frame 1, the motor 2 being electrically connected to an external power source, a transmission assembly mounted on the output shaft of the motor 2, a first sieve cylinder 3 mounted on the frame 1, the first sieve cylinder 3 having a plurality of mesh holes 4, the first sieve cylinder 3 being connected to the output shaft of the motor 2 via the transmission assembly, a spiral blade 5 being mounted inside the first sieve cylinder 3, and a scraper assembly being mounted inside the frame 1, the scraper assembly abutting against the first sieve cylinder 3. Specifically, the worker adds the dried cardamom into the first screen cylinder 3 through the feed end. Then, the motor 2 is started, and the output shaft of the motor 2 is energized and rotates, driving the first screen cylinder 3 to rotate through the transmission assembly. The cardamom generates centrifugal force under the rotation of the first screen cylinder 3, at which point the cardamom adheres tightly to the cylinder wall of the first screen cylinder 3. As the first screen cylinder 3 continues to rotate, the cardamom stalks pass through the mesh 4 and are placed outside the first screen cylinder 3. Subsequently, when the stalks pass through the scraper assembly, the scraper assembly separates the cardamom stalks exposed outside the first screen cylinder 3 from the cardamom. At the same time, the spiral blades 5 are provided inside the first screen cylinder 3. The spiral blades 5 drive the cardamom to move from the feed end to the discharge end of the first screen cylinder 3, realizing automatic feeding of the destemmed cardamom. During this movement, the movement stroke can increase the probability of the cardamom stalks passing through the mesh 4, improving the destemming efficiency.

[0021] Specifically, the frame 1 also includes a second screen cylinder 6, which contains spiral blades 5 and several mesh holes 4. The frame 1 also includes another scraper assembly that abuts against the second screen cylinder 6. The second screen cylinder 6 is located below the first screen cylinder 3. The frame 1 has a connecting pipe 7 that connects to the frame 1 and connects the discharge end of the first screen cylinder 3 to the feed end of the second screen cylinder 6. The connecting pipe 7 has a first bearing 8 and a second bearing 9. The first bearing 8 connects the first screen cylinder 3 to the connecting pipe 7, and the second bearing 9 connects the second screen cylinder 6 to the connecting pipe 7. The transmission assembly connects the first screen cylinder 3 to the second screen cylinder 6. Because the size of the first screen cylinder 3 limits the travel distance of the haystacks, some haystacks are not yet destemmed when they move from the feed end to the discharge end of the first screen cylinder 3. Therefore, a second screen cylinder 6 is added inside the frame 1, and the spiral blades 5 are also installed inside the second screen cylinder 6. After the haystacks are discharged from the discharge end of the first screen cylinder 3, they enter the second screen cylinder 6 through the connecting pipe 7. The second screen cylinder 6 rotates synchronously with the first screen cylinder 3 through the transmission assembly. During the above process, the connecting pipe 7 is fixedly connected to the frame 1. Under the action of the first bearing 8 and the second bearing 9, the first screen cylinder 3 and the second screen cylinder 6 rotate relative to the connecting pipe 7, thereby increasing the destemming time of the haystacks and improving the destemming effect.

[0022] Furthermore, in addition to the first sieve cylinder 3 and the second sieve cylinder 6, multiple identical sieve cylinders can be added to the frame 1 and connected in parallel to enable multiple sieve cylinders to perform destemming operations simultaneously, increasing the amount of destemmed haystacks fed in and improving destemming efficiency. The sieve cylinders are not interconnected and destemm the haystacks independently. Correspondingly, the scraper assembly also needs to be increased accordingly.

[0023] Specifically, the transmission assembly includes a first transmission wheel 10 and a second transmission wheel 11. The first transmission wheel 10 is connected to the output shaft of the motor 2, and the second transmission wheel 11 is connected to the first screen cylinder 3. A first transmission belt 12 is provided between the second transmission wheel 11 and the first transmission wheel 10. A third transmission wheel 13 is also provided on the first screen cylinder 3, and a fourth transmission wheel 14 is provided on the second screen cylinder 6. A second transmission belt 15 is provided between the fourth transmission wheel 14 and the third transmission wheel 13. Under the action of an external power source, the output shaft of the motor 2 rotates, and the first transmission wheel 10 rotates under the rotation of the output shaft of the motor 2. The second transmission wheel 11 rotates synchronously through the first transmission belt 12, thereby driving the first screen cylinder 3 to rotate. Synchronously, when the first screen cylinder 3 rotates, the third transmission wheel 13 rotates together with the first screen cylinder 3. The power is transmitted to the fourth transmission wheel 14 through the second transmission belt 15, and the fourth transmission wheel 14 drives the second screen cylinder 6 to rotate, realizing the synchronous rotation of the second screen cylinder 6 and the first screen cylinder 3.

[0024] Specifically, the scraper assembly includes a blade holder 16, on which a first scraper 17 and a second scraper 28 are mounted. The first scraper 17 abuts against the first sieve cylinder 3, and the second scraper 28 abuts against the second sieve cylinder 6. When the first sieve cylinder 3 and the second sieve cylinder 6 rotate, the cutting surface of the first scraper 17 abuts against the cylinder wall of the first sieve cylinder 3 to form a cutting zone. When the fruit stalk passes through the mesh 4 and through the cutting zone, the first scraper 17 cuts the fruit stalk from the fruit, thus separating the fruit stalk from the fruit. Similarly, the cutting surface of the second scraper 28 abuts against the cylinder wall of the second sieve cylinder 6.

[0025] Specifically, both the first scraper 17 and the second scraper 28 are slidably connected to the blade holder 16. A locking device is provided between the first scraper 17, the second scraper 28, and the blade holder 16. The locking device includes several bolts 19, which pass through the first scraper 17, the second scraper 28, and the blade holder 16, respectively. Nuts 20 are provided on each bolt 19. To reduce the problem of the scraper assembly colliding with the first screen cylinder 3 or the second screen cylinder 6, or to reduce the problem of poor cutting effect, the distance between the scraper assembly and the first screen cylinder 3 or the second screen cylinder 6 needs to be adjusted. Taking the first scraper 17 as an example, the first scraper 17 is slid within the blade holder 16 until it is in contact with the first screen cylinder 3 without colliding. Then, the bolts 19 are passed through the first scraper 17 and the blade holder 16. Finally, the nuts 20 are fitted onto the bolts 19 and tightened to fix the first scraper 17 to the blade holder. The second scraper 28 and the second screen cylinder 6 are adjusted in the same way. The first scraper 17 and the second scraper 28 are adjustable.

[0026] Specifically, the frame 1 is equipped with a waste trough 21, which is located below the first screen cylinder 3 and the second screen cylinder 6. The waste trough 21 is used to collect detached fruit stems, reducing environmental pollution caused by fruit stems scattering during the detachment process and lowering the labor costs for cleaning by factory staff.

[0027] Specifically, the frame is equipped with a feed chute 22 and a discharge chute 23. The feed chute 22 is connected to the feed end of the first screen cylinder 3, and the discharge chute 23 is connected to the discharge end of the second screen cylinder 6. Workers pour haystacks into the feed chute 22, which then enters the first screen cylinder 3. The feed chute acts as a funnel, allowing a large amount of haystacks to be added to the first screen cylinder 3, enabling continuous feeding without stopping the machine. Similarly, the discharge chute 23 is used to discharge the processed haystacks. The discharge chute 23 is equipped with a ramp to improve the discharge efficiency.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
