Description

Technical Field

[0001] This utility model relates to the technical field of asparagus harvesting devices, and in particular to a multi-stage soil vibrating screen for asparagus harvesting. Background Technology

[0002] After harvesting asparagus, it is necessary to sift the soil in time. When harvesting, the roots of asparagus are often covered with soil. Sifting can remove excess soil, keep the asparagus clean, and facilitate subsequent storage, transportation and sales. Sifting usually uses a sieve. The asparagus is placed on the sieve and the soil is made to fall through the sieve holes by shaking or mechanical vibration. During the sieving process, the asparagus should be handled gently to avoid damaging it and to ensure its integrity and marketability.

[0003] In the actual processing of asparagus after harvesting, the main function of the soil sieving device is to remove the soil from the roots of the asparagus. However, it often cannot sort the asparagus by size. For example, in asparagus processing plants, different sizes of asparagus have different needs. Large asparagus may be used to make canned goods, while small asparagus may be more suitable for fresh consumption or making frozen products. However, traditional soil sieving devices can only simply separate the soil and asparagus, and cannot classify them by size. This leads to the need for manual sorting afterward, which increases labor and time costs, reduces overall processing efficiency, and cannot meet the needs of fine processing of asparagus in large-scale production. Therefore, this utility model proposes a multi-stage soil sieving vibrating screen for asparagus harvesting to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a multi-stage soil-screening vibrating screen for asparagus harvesting. This solves the problem that existing traditional soil-screening devices can only simply separate soil and asparagus, and cannot classify them by size. This leads to the need for subsequent manual sorting, increasing labor and time costs and reducing overall processing efficiency.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a multi-stage soil screening vibrating screen for asparagus harvesting, including a fixed frame, a feeding hopper, a connecting frame and a conveyor belt. The feeding hopper is fixedly connected to the top of the fixed frame, a soil screening mechanism is provided above the fixed frame, a connecting frame is fixedly connected to one side of the fixed frame, a screening mechanism is provided on the connecting frame, and a conveyor belt is provided below the connecting frame.

[0006] A further improvement is made in that: the screening mechanism includes a rotating roller, a turntable, a screening belt and a rotary motor; the two ends of the connecting frame are symmetrically and rotatably connected to the rotating roller; multiple turntables are fixedly connected at equal intervals to the outer side of the rotating roller; a screening belt is connected between a group of front and rear parallel turntables; a rotary motor is fixedly installed on one side of the connecting frame; and the output end of the rotary motor is fixedly connected to one end of one of the rotating rollers.

[0007] A further improvement is that the cross-section of the screening belt is O-shaped, the material of the screening belt is rubber, and the two sides of the screening belt are symmetrically provided with separating edges.

[0008] A further improvement is that the rotary motor is provided with a protective shell on its outer side, and the outer side of the protective shell is provided with multiple anti-collision strips, the anti-collision strips being rectangular in shape.

[0009] A further improvement is made in that: the soil screening mechanism includes a shock-absorbing component, a material support frame, a screen plate, a vibrating motor, and an assembly frame. A set of shock-absorbing components is symmetrically fixedly connected to both sides of the top of the fixed frame. The top of the shock-absorbing component is fixedly connected to the material support frame. The bottom of the material support frame is provided with a screen plate. A vibrating motor is fixedly installed on one side of the screen plate through the assembly frame.

[0010] A further improvement is that the shock absorption assembly includes shock absorption springs and rubber shock absorbers. Rubber shock absorbers are fixedly connected to both sides of the top of the fixed frame and both sides of the bottom of the screen plate. A shock absorption spring is connected between a group of parallel rubber shock absorbers.

[0011] A further improvement is that: a locking seat is symmetrically fixedly connected to one side of the material support frame, a baffle is provided on one side of the material support frame, the bottom of the baffle is in contact with the inner side of the material support frame, and locking blocks are symmetrically fixedly connected to both sides of the baffle, with the outer wall of the locking block engaging with the inner side of the locking seat.

[0012] The beneficial effects of this utility model are as follows: the rotary motor drives the rotating roller connected to its output end to rotate, and multiple turntables are installed on the rotating roller, so that the rotating roller can drive multiple turntables to rotate simultaneously. A set of front and rear parallel turntables rub against each other through the screening belt, thereby driving multiple screening belts to rotate linearly back and forth. After the asparagus falls to the top of the screening belt, if the diameter of the asparagus is larger than the gap between the two screening belts, the screening belt drives the large asparagus to move towards one side of the connecting frame and out of the material. If the diameter of the asparagus is smaller than the gap between the two screening belts, the asparagus passes through the gap and falls to the top of the conveyor belt. The conveyor belt drives the small asparagus to move out of the material and out of the material. This is used to automatically classify the asparagus according to its diameter and improve the overall processing efficiency of asparagus. Attached Figure Description

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a multi-stage soil-screening vibrating screen for asparagus harvesting, including a fixed frame 1, a feeding hopper 2, a connecting frame 3, and a conveyor belt 4. The feeding hopper 2 is fixedly connected to the top of the fixed frame 1, a soil-screening mechanism is provided above the fixed frame 1, and a connecting frame 3 is fixedly connected to one side of the fixed frame 1. A screening mechanism is provided on the connecting frame 3, and a conveyor belt 4 is provided below the connecting frame 3. First, the asparagus with soil is placed in the soil-screening mechanism, and most of the soil on the surface of the asparagus is removed by the soil-screening mechanism, reducing the workload of washing the asparagus. The soil screened out is guided to the bottom of the fixed frame 1 through the feeding hopper 2, and the asparagus enters the screening mechanism. The screening mechanism automatically classifies the asparagus according to its diameter, improving the overall processing efficiency of the asparagus. Moreover, the soil-screening and screening mechanisms work together to perform multi-stage screening of the asparagus.

[0020] The soil screening mechanism includes a shock-absorbing component 9, a material support frame 10, a screen plate 11, a vibration motor 12, and an assembly frame 13. A set of shock-absorbing components 9 are symmetrically fixed to both sides of the top of the fixed frame 1. The top of the shock-absorbing component 9 is fixedly connected to the material support frame 10. The bottom of the material support frame 10 is provided with a screen plate 11. A vibration motor 12 is fixedly installed on one side of the screen plate 11 through the assembly frame 13. The vibration motor 12 generates excitation force through the rotation of the eccentric block, causing vibration between the material support frame 10 and the fixed frame 1. The soil on the asparagus is shaken off by the vibration and falls through the screen plate 11 into the feed hopper 2, and then falls through the feed hopper 2 into the bottom of the fixed frame 1, while the asparagus is trapped on the top of the screen plate 11.

[0021] The shock absorption assembly 9 includes shock absorption springs and rubber shock absorbers. Rubber shock absorbers are fixedly connected to both sides of the top of the fixed frame 1 and both sides of the bottom of the screen plate 11. A shock absorption spring is connected between a group of parallel rubber shock absorbers. The shock absorption springs and rubber shock absorbers are installed between the material support frame 10 and the fixed frame 1 to buffer and support the material. They work together to absorb the energy generated by vibration, reduce the impact of vibration on the base and the surrounding environment, and ensure the stability of the screen box during vibration.

[0022] A mounting base 14 is symmetrically fixedly connected to one side of the material support frame 10. A baffle 15 is provided on one side of the material support frame 10. The bottom of the baffle 15 is attached to the inner side of the material support frame 10. A locking block 16 is symmetrically fixedly connected to both sides of the baffle 15. The outer wall of the locking block 16 is engaged with the inner side of the mounting base 14. One side of the material support frame 10 is inclined towards the screening belt 7. The vibration of the material support frame 10 itself drives the asparagus to move automatically towards the screening belt 7, so that the asparagus automatically falls onto the screening belt 7. The baffle 15 is engaged with the mounting base 14 through the locking block 16, so that the locking block 16 is fixed to one side of the material support frame 10, blocking the channel for the asparagus to move towards the screening belt 7. After the material support frame 10 drives the asparagus to vibrate and achieve the expected effect of cleaning the soil, the baffle 15 is pulled out from one side of the material support frame 10 and the channel is reopened.

[0023] The screening mechanism includes a rotating roller 5, a turntable 6, a screening belt 7, and a rotary motor 8. The two ends of the connecting frame 3 are symmetrically and rotatably connected to the rotating roller 5. Multiple turntables 6 are fixedly connected at equal intervals to the outer sides of the rotating roller 5. A screening belt 7 is connected between a group of parallel turntables 6. A rotary motor 8 is fixedly installed on one side of the connecting frame 3. The output end of the rotary motor 8 is fixedly connected to one end of one of the rotating rollers 5. The screening belt 7 has an O-shaped cross-section and is made of rubber. Symmetrical separating edges are provided on both sides of the screening belt 7. The rotary motor 8 drives the rotating roller 5 connected to its output end to rotate. Multiple turntables 6 are mounted... Installed on the rotating roller 5, the rotating roller 5 can drive multiple rotating discs 6 to rotate simultaneously, and a group of parallel rotating discs 6 rub against each other through the screening belt 7, thereby driving multiple screening belts 7 to rotate linearly back and forth. After the asparagus falls to the top of the screening belt 7, if the diameter of the asparagus is larger than the gap between the two screening belts 7, the screening belt 7 drives the large asparagus to move towards one side of the connecting frame 3 and out of the material. If the diameter of the asparagus is smaller than the gap between the two screening belts 7, the asparagus passes through the gap and falls to the top of the conveyor belt 4. The conveyor belt 4 drives the small asparagus to move out of the material and out of the material, so as to automatically classify the asparagus according to its diameter and improve the overall processing efficiency of asparagus.

[0024] The rotary motor 8 is provided with a protective shell on its outer side, and multiple anti-collision strips are provided on the outer side of the protective shell. The anti-collision strips are rectangular in shape. The protective shell and anti-collision strips can isolate the rotary motor 8 from external objects, prevent external objects from directly contacting the rotary motor 8, and play a protective role for the rotary motor 8.

[0025] The asparagus harvesting method uses a multi-stage vibrating screen. A rotating motor 8 drives a rotating roller 5 connected to its output end to rotate. Multiple turntables 6 are installed on the rotating roller 5, so the rotating roller 5 can drive multiple turntables 6 to rotate simultaneously. A set of parallel turntables 6 rub against each other through the screening belt 7, thereby driving multiple screening belts 7 to rotate linearly back and forth. After the asparagus falls to the top of the screening belt 7, if the diameter of the asparagus is larger than the gap between two screening belts 7, the screening belt 7 drives the large asparagus to move towards one side of the connecting frame 3 and outwards. If the diameter of the asparagus is smaller than the gap between two screening belts 7, the asparagus passes through the gap and falls to the top of the conveyor belt 4. The conveyor belt 4 drives the small asparagus to move outwards and outwards, which is used to automatically classify the asparagus according to its diameter and improve the overall processing efficiency of asparagus.
