Description

Technical Field

[0001] This utility model relates to the technical field of goji berry screening equipment, specifically a goji berry fresh fruit grading machine. Background Technology

[0002] In order to further enhance the value of goji berries, increase the economic benefits of the industry, and meet the market demand for deep-processed goji berries such as fresh goji berry products, juice, and wine, the fresh fruit processing technology must first grade the fresh fruit before it enters the next drying or juicing process. This will meet the production needs during the goji berry ripening season and greatly improve the upgrading and development and economic benefits of the goji berry industry.

[0003] Currently, fresh goji berries are usually graded manually. This method is labor-intensive, has high production costs, and the grading effect is not ideal. It can only meet the needs of small-batch production and cannot meet the requirements of large-scale production during the goji berry ripening season. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a goji berry fresh fruit grading machine, which has the following beneficial effects:

[0016] The combination of multiple sets of sieve holes of different diameters on the sieve plate and the vibration of the vibrating motor can quickly grade a large number of fresh goji berries by size, greatly improving grading efficiency and meeting the needs of large-scale production.

[0017] The separator strips on the sieve plate can effectively prevent the fresh goji berries from piling up randomly or interfering with each other during the sieving process, allowing the berries to pass through the sieve holes in an orderly manner along the set path, which significantly improves the accuracy of grading and ensures that the size difference of each grade of berries is smaller and the quality is more uniform.

[0018] The spiral design on the feeding screw allows the fresh goji berries to be pushed evenly inside the discharge pipe. Combined with the structure that allows the discharge pipe to move at the top of the feed box, this ensures that the fresh goji berries enter the feed box evenly and are then evenly distributed on the screen plate, providing a good prerequisite for subsequent precise screening.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model discloses a fresh goji berry grading machine, including a screening box 1 and a material cylinder 12. The screening box 1 has an inclined screen plate 2 with multiple sets of screen holes of different diameters. The rear end of the screening box 1 has a discharge hole. The screening box 1 has a drawer groove 4 located below the screen plate 2. The drawer groove 4 has a drawer box 5 inside. The drawer box 5 holds multiple material receiving boxes 6. Vibration motors 7 are symmetrically arranged on both sides of the screening box 1.

[0026] The screening box 1 has a feeding box 10 at its front end, and a material cylinder 12 is located above the feeding box 10. The bottom of the material cylinder 12 has a discharge pipe 13. A first motor 18 is located above the material cylinder 12. The output end of the first motor 18 has a feeding screw 15 that passes through the discharge pipe 13. A positioning block 16 and a driving block 20 are symmetrically arranged on the outer wall of the discharge pipe 13. A second motor 14 is fixedly installed at the top of the feeding box 10. The output end of the second motor 14 has a driving screw 19 that passes through the driving block 20. A guide rod 17 that passes through the positioning block 16 is provided on one side of the feeding box 10.

[0027] In this embodiment, the sieve plate 2 is provided with multiple isolation strips 3.

[0028] In this embodiment, a spiral ribbon is wound around the feeding screw 15, and the periphery of the spiral ribbon is close to the inner wall of the discharge pipe 13.

[0029] In this embodiment, both the first motor 18 and the second motor 14 are servo motors.

[0030] In this embodiment, the four corners of the drawer box 5 are fixed to one side of the screening box 1 by screws 8, which can improve the stability of the drawer box 5 during use.

[0031] In this embodiment, the drawer box 5 is provided with multiple handles, which makes the drawer box 5 easy to operate.

[0032] Transport all components of the goji berry fresh fruit grading machine to the designated work site, ensuring the ground is flat and firm to provide a foundation for stable equipment operation;

[0033] Place the screening box 1 in a suitable position, install the screen plate 2 at an angle inside the screening box 1, pre-set multiple sets of screen holes with different apertures on the screen plate 2, and install multiple isolation strips 3;

[0034] A discharge hole is reserved at the rear end of the screening box 1. A drawer slot 4 is installed below the screen plate 2. The drawer box 5 is placed in the drawer slot 4. The drawer box 5 is fixed to one side of the screening box 1 with screws 8 at the four corners. Then, multiple receiving boxes 6 are placed in the drawer box 5.

[0035] Turn on the power to start the first motor 18 and the second motor 14. Since both the first motor 18 and the second motor 14 are servo motors, the motor speed can be precisely adjusted according to actual needs.

[0036] The fresh goji berries to be graded are poured into the feed cylinder 12. The first motor 18 drives the feeding screw 15 to rotate. The spiral ribbon coiled on the feeding screw 15 rotates accordingly, and the periphery of the spiral ribbon is close to the inner wall of the discharge pipe 13. Under the push of the spiral ribbon, the fresh goji berries are discharged downward along the discharge pipe 13.

[0037] The second motor 14 drives the drive screw 19 to rotate. The drive screw 19, in cooperation with the drive block 20, allows the discharge pipe 13 to move within a certain range at the top of the feed box 10 under the constraint of the positioning block 16 and the guide rod 17, so that the fresh goji berries can fall evenly onto the screen plate 2 at multiple positions within the feed box 10.

[0038] Fresh goji berries enter the screening box 1 from the feed box 10 and fall onto the inclined screen plate 2. At this time, the vibration motor 7 is started, and the screen plate 2 vibrates under the action of the vibration motor 7.

[0039] At this time, the fresh goji berries roll and slide on the vibrating sieve plate 2. Guided by the isolation strip 3, they move in an orderly manner to the sieve holes of different sizes. Fresh goji berries of different sizes fall through the sieve holes of the corresponding size. Smaller fruits first pass through the sieve holes of smaller size, while larger fruits continue to roll to the sieve hole of the appropriate size and fall. Fresh goji berries that pass through the sieve holes fall into the corresponding receiving box 6 in the drawer box 5 below. Fresh goji berries that fail to pass through the sieve holes roll along the sieve plate 2 to the rear end of the screening box 1 and are discharged from the discharge hole.

[0040] After grading, the drawer box 5 can be easily pulled out from the drawer slot 4 using the multiple handles on the drawer box 5 to collect different grades of fresh goji berries from each receiving box 6, as well as ungraded berries discharged from the discharge hole.
