Description

Technical Field

[0001] The present application relates to the technical field of vegetable processing, and in particular to a frozen vegetable impurity removal and screening machine. Background Art

[0002] Freezing vegetables makes it easier to store and manage, and can maintain their usability for a long time. After the vegetables are taken out of the soil, impurities such as dirt will remain. If they are frozen directly without being cleaned, the dirt, impurities and other bacteria attached to the vegetables will contaminate the vegetables and accelerate the deterioration of the vegetables. Moreover, after freezing, the impurities have stronger adhesion to the vegetables, making it more complicated to clean the vegetables. Therefore, impurities are generally cleaned before the vegetables are frozen for storage.

[0003] For some block-shaped vegetables, such as carrots and taro, when removing impurities, in order to improve the consistency of vegetables, vegetables of different sizes may be screened. Currently, common equipment includes a drum cleaning and impurity removal machine, which cleans and removes impurities by rotating the drum. However, after cleaning and impurities removal, the vegetables need to be put into the screening equipment for screening again, which is more troublesome. In addition, screening can be performed while cleaning and impurities removal. After screening, the smaller block-shaped vegetables fall through the gap of the drum. Although screening can be performed, the sewage after cleaning will also flow out of the drum, causing secondary pollution. Impurity removal treatment is still required later, which is inconvenient to use. Therefore, a frozen vegetable impurity removal and screening machine is proposed to solve the above-mentioned problems. Utility Model Content

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The embodiment of the present application discloses a frozen vegetable impurity removal and screening machine, comprising a cleaning drum 1, at least one screening drum 2, a driving member 3 and a conveying guide plate 4. The cleaning drum 1 is hollow, and a plurality of high-pressure spray heads 11 are arranged inside the cleaning drum 1 for spraying and cleaning the vegetables in the cleaning drum 1. The cleaning liquid sprayed by the high-pressure spray heads 11 flows out through the leakage holes of the cleaning drum 1. The driving member 3 can drive the cleaning drum 1 to perform a circular motion. The driving member 3 can be a device capable of performing a circular motion, such as a motor. A gear 7 is arranged at the output end of the driving member 3. A gear ring 71 meshing with the gear 7 is arranged on the outer wall of the cleaning drum 1. The gear 7 is driven by the driving member 3 to drive the gear ring 71 to rotate. The cleaning drum 1 is rotated by the driving member 3, and the conveying guide plate 4 is spirally arranged on the circumferential inner wall of the cleaning drum 1 and extends to the output end of the screening drum 2. When the driving member 3 drives the cleaning drum 1 to rotate, the vegetables are tumbled and stirred in the cleaning drum 1, thereby increasing the contact area with the cleaning liquid, improving the cleaning and impurity removal effect, and avoiding the residual dirt, sediment and other bacteria attached to the surface of the vegetables after freezing, which accelerates the deterioration and decay of the vegetables. The screening drum 2 is connected to the output end of the cleaning drum 1 for screening the washed vegetables. The vegetables after cleaning and impurity removal in the cleaning drum 1 are conveyed by the conveying guide plate 4 to the screening drum 2 for screening according to the block size, thereby improving the uniformity of the vegetables.

[0034] A water pipe 9 is axially provided inside the cleaning drum 1, and a plurality of high-pressure spray heads 11 are equidistantly arranged on the water pipe 9. When in use, the input end of the water pipe 9 can be connected to an external water supply device to output spray liquid to the high-pressure spray head 11. The spray liquid ejected with high pressure by the plurality of equidistantly arranged high-pressure spray heads 11 cleans impurities on the surface of vegetables inside the cleaning drum 1.

[0035] Furthermore, the screening cylinder 2 includes an inner cylinder 21 and an outer cylinder 22, each of which is composed of a plurality of intercepting rods 201 equidistantly arranged around the circumference of the central axis of the screening cylinder 2 and connecting rings 202 connected to both ends of the intercepting rods 201. The connecting ring 202 on the inner cylinder 21 is rotatably connected to the connecting ring 202 on the outer cylinder 22, and the screening of vegetable materials of different sizes is achieved by changing the position of the intercepting rod 201 on the outer cylinder 22 relative to the intercepting rod 201 on the inner cylinder 21. When in use, the outer cylinder 22 is rotated so that the outer cylinder 22 drives the intercepting rod 201 on the outer cylinder 22 to approach the intercepting rod 201 on the inner cylinder 21. When the intercepting rod 201 on the outer cylinder 22 is located directly above the intercepting rod 201 on the inner cylinder 21, as shown in FIG. Figure 5 As shown, the interception rod 201 on the outer cylinder 22 will not intercept between two adjacent interception rods 201 on the inner cylinder 21. At this time, large pieces of vegetables can fall from between the two adjacent interception rods 201, and the block vegetables that have not fallen will fall from the output end of the screening cylinder 2 after being intercepted, so as to achieve the screening of block vegetables of different sizes. For some vegetables with smaller particle sizes, when adjustment is required, the outer cylinder 22 is rotated so that the interception rod 201 on the outer cylinder 22 is located between two adjacent interception rods 201 of the inner cylinder 21, as shown in FIG. Figure 6 As shown, the gap between the interception bars 201 is adjusted to be smaller, thereby intercepting some smaller pieces of vegetables.

[0036] And the number of screening drums 2 is at least one. When multi-stage screening is required, Figure 7 As shown, another screening drum 2 can be set at the output end of the screening drum 2, and the gap between the intercepting bars 201 of this screening drum 2 is smaller than the gap between the intercepting bars 201 on the front screening drum 2, so as to realize multi-stage screening of block vegetables and make the screening more detailed.

[0037] Furthermore, after adjusting the positions of the inner cylinder 21 and the outer cylinder 22, in order to lock the inner cylinder 21 and the outer cylinder 22, a locking assembly is also included, the locking assembly includes a fixing plate 5 arranged on the connecting ring 202 at the end of the inner cylinder 21 and a locking pin 51 threadedly connected to the fixing plate 5, and the connecting ring 202 of the outer cylinder 22 is provided with a plurality of locking holes 52 equidistantly arranged around the axis of the outer cylinder 22, the locking holes 52 correspond to the locking pins 51, after rotating the outer cylinder 22 to the corresponding position, the locking pin 51 is rotated downward to make the locking pin 51 threadedly connected to the locking hole 52, so as to fix the position of the outer cylinder 22 on the inner cylinder 21, and the number of the locking assemblies is at least two, and they are equidistantly arranged along the circumference of the axis of the screening cylinder 2, so as to further improve the connection stability between the outer cylinder 22 and the inner cylinder 21.

[0038] Furthermore, a plurality of debris removal protrusions 6 are provided on the inner wall of the cleaning drum 1. When the vegetables entering the cleaning drum 1 come into contact with the debris removal protrusions 6, the debris removal protrusions 6 have a stronger impact on the stains attached to the surface of the vegetables, which is beneficial for separating them. The vegetables can be cleaned at different angles as the cleaning drum 1 rotates, and impurities in the depressions on the surface of the vegetables can be removed, resulting in a better cleaning effect. The end of the debris removal protrusion 6 facing the axis of the cleaning drum 1 is arc-shaped, and the debris removal protrusion 6 can be made of a material with a certain degree of elasticity. When the vegetables come into contact with the debris removal protrusion 6, no damage is caused to the surface of the vegetables.

[0039] Furthermore, a receiving box 8 is movably connected to the bottom of the cleaning drum 1 and the screening drum 2. The receiving box 8 can be used to support the cleaning drum 1 and the screening drum 2, and the interior of the receiving box 8 is provided with a water storage bin 81 for containing cleaning waste water of the cleaning drum 1 and a material storage bin 82 for containing screened vegetables. The water storage bin 81 and the material storage bin 82 are respectively provided with an outlet pipe 83 and a discharge trough 84. The cleaning wastewater and impurities flowing out of the cleaning drum 1 flow into the water storage bin 81 and are discharged through the outlet pipe 83, while the block vegetables falling from the screening drum 2 fall into the material storage bin 82 for collection, and some larger block vegetables screened out are discharged through the output end of the screening drum 2 for easy classification and collection.

[0040] Furthermore, the interior of the water bin 81 and the material bin 82 are both provided with an inclined guide plate 85, which is inclined downward toward one side of the discharge trough 84, and can guide the sewage in the water bin 81 and the vegetables in the material bin 82 to facilitate discharge.

[0041] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
