Description

Technical Field

[0001] This utility model relates to a grading and screening device for Japanese raisin tree fruit, specifically a grading and screening device that facilitates the screening of Japanese raisin tree fruit, and belongs to the technical field of Japanese raisin tree fruit screening equipment. Background Technology

[0002] Japanese raisin tree fruit, also known as longevity fruit, wood coral, chicken spur, etc., is the dried mature seed of Japanese raisin tree, a plant of the Rhamnaceae family. Its fruit stalk is the edible part. In the processing of Japanese raisin tree fruit, screening devices are often used to distinguish Japanese raisin tree fruit of different sizes.

[0003] In existing grading and screening devices, the irregular shape of the Japanese raisin tree, its slender and easily tangled stems, and its uneven surface make it easy for the fruit to get stuck in the sieve holes, causing blockage. Most grading and screening devices do not have anti-blocking functions, so the blockage of the sieve holes will affect the screening efficiency of the Japanese raisin tree fruit during the screening process, thus reducing the practicality of the device.

[0004] Therefore, a grading and screening device for easy screening of Japanese raisin tree fruit is proposed here. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figure 1 and Figure 2 This utility model provides a grading and screening device for easy screening of jujube fruits, including a housing 1. The housing 1 is equipped with a screening mechanism 2, which includes several screen bodies 201. The outer surface of each screen body 201 is fixedly connected to the inner wall of the housing 1. The screen holes on the screen body 201 decrease in size from top to bottom. Two sets of casters 4 are fixedly installed on the bottom surface of the housing 1. Each caster 4 has a brake pad 5 fixedly installed on its outer surface. The installation of the casters 4 makes it convenient for workers to move the device, thereby increasing the ease of movement of the device. The installation of the brake pad 5 locks the casters 4, thereby preventing the casters 4 from rotating on their own.

[0017] Please refer to this carefully. Figures 1-5 A vibration motor 202 is fixedly installed on the left side of the machine casing 1. An installation plate 203 is fixedly installed on the outer surface of the machine casing 1. An airbag block 204 is fixedly installed on the upper surface of the installation plate 203. Two connecting pipes 205 are fixedly connected to the outer surface of the airbag block 204. A one-way valve 206 is fixedly connected to the outer surface of each connecting pipe 205. The two connecting pipes 205 cooperate with the one-way valve 206 to allow one connecting pipe 205 to supply gas into the airbag block 204 and the other connecting pipe to discharge the gas from the airbag block 204. A feed hopper 6 is fixedly connected to the upper surface of the machine casing 1. A collection box 7 is set inside the machine casing 1. The installation of the feed hopper 6 makes it convenient for workers to fill the machine casing 1 with jujube fruits. The installation of the collection box 7 serves to collect the jujube fruits that flow out last.

[0018] Please refer to this carefully. Figure 3 , Figure 4 and Figure 5 An air jet pipe 207 is fixedly installed on the inner wall of the casing 1. One end of a connecting pipe 205 extends into the interior of the air jet pipe 207. Several solenoid valves 208 are fixedly connected to the outer surface of the air jet pipe 207. A pressing assembly 3 is provided on the outside of the casing 1. The pressing assembly 3 includes a rotating motor 301. The side of the rotating motor 301 near the casing 1 is fixedly connected to the outer surface of the casing 1. A connecting plate 302 is fixedly installed on the outer surface of the casing 1. The output end of the rotating motor 301 passes through the connecting plate 302 and is fixedly installed on a turntable 303. A connecting post 304 is fixedly installed on the left side of the turntable 303. A... A movable frame 305 is provided, the inner wall of which is in contact with the outer surface of the connecting column 304. A pressing plate 306 is fixedly installed at the bottom end of the movable frame 305. Two sets of connecting springs 307 are fixedly installed on the inner bottom wall of the airbag block 204. A movable plate 308 is fixedly installed at the top of the two sets of connecting springs 307. The power provided by the rotating motor 301, together with the turntable 303 and the connecting column 304, drives the movable frame 305 and the pressing plate 306 to reciprocate pressing the airbag block 204. At the same time, with the elastic force of the connecting springs 307, the airbag block 204, together with the one-way valve 206, intermittently delivers gas into the jet pipe 207.

[0019] Please refer to this carefully. Figure 4 A limiting block 8 is fixedly installed on the left side of the connecting plate 302. The inner wall of the limiting block 8 is slidably connected to the outer surface of the moving frame 305. The installation of the limiting block 8 plays a role in restricting the movement trajectory of the moving frame 305, thereby ensuring the stability of the movement of the moving frame 305.

[0020] Please refer to this carefully. Figure 4 Two sets of telescopic columns 9 are fixedly installed on the bottom surface of the movable plate 308. The bottom end of each telescopic column 9 is fixedly connected to the inner bottom wall of the airbag block 204. The installation of the telescopic columns 9 plays a role in restricting the movement trajectory of the movable plate 308, thereby preventing the movable plate 308 from deviating from the movement trajectory when moving.

[0021] When using this utility model: In use, the worker first turns on the vibration motor 202 and the rotation motor 301 through the external remote control device. The vibration motor 202 provides the vibration force, which causes the screen body 201 to vibrate. Then the worker fills the inside of the machine box 1 with the jujube fruit through the feed hopper 6. Thus, the multiple screen bodies 201 are used to achieve the purpose of grading and screening the jujube fruit. During the screening process, the power provided by the rotating motor 301 drives the turntable 303 to rotate, which in turn drives the connecting column 304 to rotate. Under the restriction of the limit block 8, the connecting column 304 drives the moving frame 305 and the pressing plate 306 to move back and forth up and down. This causes the pressing plate 306 to press the airbag block 204 back and forth. When the airbag block 204 is pressed, the connecting pipe 205 on one side delivers gas into the air jet pipe 207. When the airbag block 204 is released, under the action of the connecting spring 307, the connecting pipe 205 on the other side delivers gas into the airbag block 204. This achieves the effect of intermittently delivering gas into the air jet pipe 207. At the same time, under the action of the external controller, each solenoid valve 208 is opened in sequence, thereby achieving the purpose of air jet treatment on the screen body 201 from top to bottom, thus preventing the jujube fruit from clogging the screen body 201.
