Description

Technical Field

[0001] This utility model relates to the field of wheat sorting technology, specifically a gravity grading and destoner for wheat sorting. Background Technology

[0002] Destoning of wheat can be accomplished using mechanical equipment. Destoning can be carried out by screening or gravity separation. Screening removes sand and gravel by utilizing the difference in shape and size between the sand and gravel and the raw material, and by using the difference in the shape and size of the sieve holes. Gravity separators remove sand and gravel by utilizing the difference in specific gravity between the sand and gravel and the raw material, and by using continuous vibration or external force.

[0003] The existing Chinese patent with publication number CN216420110U discloses a gravity-based wheat grading and destoning machine, including a base. Vibrators are fixedly installed at both ends of the top surface of the base. Limiting plates are fixedly installed at both ends of the top surface of the base. A destoning box is fixedly installed on the top surface of the vibrators. A feed hopper is fixedly connected to the top surface of the destoning box. Destoning screen plates are movably sleeved on both sides of the destoning box. A through rod is fixedly installed at one end of the inner side of the destoning screen plate. Limiting mechanisms located at one end of the through rod are movably sleeved on both ends of the inner cavity of the destoning box. A spring cavity is opened on the side of the destoning box. A locking mechanism is movably sleeved inside the spring cavity. A feed pipe is fixedly connected to the middle of the bottom surface of the destoning box.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: during the screening process, a large amount of wheat bran and other dust will be generated. If these dust particles are not treated in time, they will affect the sorting quality of wheat and may also spread into the surrounding environment, causing pollution.

[0005] Therefore, how to design a gravity grading and destoning machine for wheat has become a problem that we need to solve. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a gravity grading and destoner for wheat sorting, which has the following beneficial effects:

[0019] Firstly, by setting up the feeding assembly, wheat can be added into the feeding hopper during feeding, allowing it to enter the feeding pipe along the hopper, and finally discharged from multiple distribution pipes to different positions in the sorting box. During the feeding process, a rotary motor can be started to drive the gears to rotate, which in turn drives the gear ring to rotate, which in turn drives the feeding pipe to rotate. This makes the wheat more dispersed during feeding, reducing the situation where wheat piles up together, facilitating sorting, and improving sorting efficiency.

[0020] Secondly, by setting up the dust removal component, the fan can be activated during the screening process to suck the wheat bran and other dust generated during screening into the dust suction hood, and then discharge it into the collection box through the dust suction pipe. The air is discharged from the fan after passing through the filter screen, and the dust is intercepted by the filter screen in the collection box and finally falls into the cleaning box. The cleaning box can be removed periodically to clean the collected dust, thereby removing wheat bran and other dust from the wheat, improving the sorting quality of wheat, and preventing the dust from spreading to the surrounding environment and causing pollution.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: a gravity grading and destoning machine for wheat sorting, including a sorting box 1, a vibrating base 2, a feeding assembly 3, and a chip removal assembly 4. The vibrating base 2 is located at the bottom of the sorting box 1, and a vibrating disc 21 is installed inside the vibrating base 2. A vibrating motor 22 is fixedly installed at the bottom of the vibrating disc 21, and springs 23 are installed at the four corners of the bottom of the vibrating disc 21. The sorting box 1 is equipped with two screen plates 11 that are spaced apart vertically. There are installation openings 12 on both sides of the sorting box 1. The screen plates 11 are fixedly installed in the installation openings 12 by bolts. Through the cooperation of the sorting box 1 and the vibrating base 2, after wheat is added to the sorting box 1, the vibrating motor 22 can be started to drive the vibrating disc 21 to vibrate, so that the vibrating disc 21 drives the sorting box 1 to vibrate, thereby grading and screening the wheat by the screen plates 11, so that the stones mixed in the wheat are discharged from the installation openings 12, and the wheat falls to the bottom of the sorting box 1 through the screen plates 11 and is discharged from the discharge pipe at the bottom of the sorting box 1.

[0030] Specifically, the feeding assembly 3 is located on the top of the sorting box 1. The feeding assembly 3 includes a feeding pipe 31 rotatably mounted on the top of the sorting box 1 and a drive assembly 32 for driving the feeding pipe 31 to rotate. The top of the feeding pipe 31 is rotatably connected to a feeding hopper 33, and the bottom of the feeding pipe 31 is provided with multiple distribution pipes 34. The top of the sorting box 1 is fixedly mounted with a housing 35, and the feeding pipe 31 is fixedly mounted on the top of the housing 35. Through the setting of the feeding assembly 3, wheat can be added into the feeding hopper 33 during feeding, so that the wheat enters the feeding pipe 31 along the feeding hopper 33, and finally is discharged from the multiple distribution pipes 34 to different positions in the sorting box 1, reducing the situation of wheat piling up together, facilitating sorting, and improving sorting efficiency.

[0031] Specifically, the drive assembly 32 includes a rotary motor 321 fixedly installed inside the housing 35. The output end of the rotary motor 321 is fixedly connected to a gear 322. A gear ring 323 that meshes with the gear 322 is fixedly fitted on the feed pipe 31. By setting the drive assembly 32, during the feeding process, the rotary motor 321 can be started to drive the gear 322 to rotate, which in turn drives the gear ring 323 to rotate, which in turn drives the feed pipe 31 to rotate, thereby making the wheat more dispersed during feeding.

[0032] Specifically, the chip removal assembly 4 includes a collection box 41 fixedly installed on the back of the sorting box 1. Inside the sorting box 1, a chip suction hood 42 is fixedly installed above each sieve plate 11. A chip suction pipe 43 connects the chip suction hood 42 and the collection box 41. A fan 44 is fixedly installed on one side of the collection box 41. A filter screen 45 is fixedly installed inside the collection box 41 near the fan 44. A cleaning box 46 is slidably installed on one side of the collection box 41. Through the setting of the chip removal assembly 4, during the screening process, the fan 44 can be started to suck the wheat bran and other dust generated during screening into the chip suction hood 42, and then discharged into the collection box 41 through the chip suction pipe 43. The air is discharged from the fan 44 after passing through the filter screen 45. The dust is intercepted by the filter screen 45 in the collection box 41 and finally falls into the cleaning box 46. The cleaning box 46 can be periodically removed to clean the collected dust, thereby removing wheat bran and other dust from the wheat, improving the sorting quality of the wheat, and preventing the dust from spreading to the surrounding environment and causing pollution.

[0033] The working process of this utility model is as follows: During feeding, wheat can be added into the feed hopper 33, allowing it to enter the feed pipe 31 along the feed hopper 33, and finally discharged from multiple distribution pipes 34 to different positions within the sorting box 1. During the feeding process, the rotary motor 321 can be started to drive the gear 322 to rotate, which in turn drives the gear ring 323 to rotate, which in turn drives the feed pipe 31 to rotate. This makes the wheat more dispersed during feeding, reducing the likelihood of wheat piling up. After the wheat is added to the sorting box 1, the vibration motor 22 can be started to drive the vibrating plate 21 to vibrate, which in turn drives the sorting box 1 to vibrate, thereby causing the sieve plate 11 to grade the wheat. The screening process removes stones mixed in with the wheat from the installation port 12. The wheat falls through the sieve plate 11 to the bottom of the sorting box 1 and is discharged from the discharge pipe at the bottom of the sorting box 1. During the screening process, the blower 44 can be activated to suck the wheat bran and other dust generated during screening into the dust suction hood 42. The dust is then discharged into the collection box 41 through the dust suction pipe 43. The air is discharged from the blower 44 after passing through the filter screen 45. The dust is intercepted by the filter screen 45 in the collection box 41 and finally falls into the cleaning box 46. The cleaning box 46 can be periodically removed to clean the collected dust, thereby removing wheat bran and other dust from the wheat, improving the sorting quality of the wheat, and preventing the dust from spreading into the surrounding environment and causing pollution.
