Abstract
Description
Technical fields:
[0001] This utility model relates to the technical field of Caragana korshinskii seed collection equipment, and in particular to a Caragana korshinskii seed collection device. Background technology:
[0002] Caragana korshinskii is a sand-loving shrub with an extremely developed root system. It is highly adaptable and has a high survival rate, making it an excellent tree species for windbreak and sand fixation, and for soil and water conservation in central and western China. Caragana korshinskii seeds are rich in oil, nitrogen, and nutrients. Currently, seeds are mainly harvested manually, which is time-consuming and labor-intensive. If harvesting is not timely, the pods naturally split open, scattering seeds on the sand, which are difficult to collect and result in waste. Therefore, automated mechanized harvesting devices for Caragana korshinskii have emerged on the market. The general structure of existing harvesting devices includes a rotating shaft with several comb teeth. The comb teeth rotate at high speed to scrape the pods off the branches for collection. However, in actual use, many Caragana korshinskii plants in their natural state have branches that are blown haphazardly by the wind, causing the comb teeth to frequently break the branches and damage the plants. This situation urgently needs improvement. Utility Model Content:
[0003] The purpose of this invention is to provide a seed collection device for Caragana korshinskii to solve the technical problem that Caragana korshinskii branches are easily broken during use in existing seed collection devices.
[0004] The present invention relates to a seed collection device for *Caragana korshinskii*, comprising a horizontally arranged central shaft rotatably connected to the inner wall of a collection box, rollers mounted at the bottom of the collection box, and a central shaft connected to a motor. A plurality of comb-tooth assemblies are evenly distributed along the length of the central shaft. Each comb-tooth assembly comprises a plurality of comb-tooth units evenly arranged along the circumference of the central shaft, each comb-tooth unit including comb teeth. A centrifugal telescopic column assembly is installed within the comb teeth. When the central shaft rotates at high speed, the centrifugal telescopic column assembly extends outward, and is used to straighten the *Caragana korshinskii* branches.
[0005] Furthermore, the centrifugal telescopic column assembly includes a telescopic column, a sliding column connected to the bottom end of the telescopic column, a sliding cavity provided in the comb teeth, a through hole opened at the top end of the comb teeth, the through hole communicating with the sliding cavity, the sliding column slidably connected with the sliding cavity, the telescopic column slidably connected with the through hole, and a compression spring fitted on the telescopic column, the compression spring contacting the sliding column.
[0006] Furthermore, T-shaped grooves are provided on both sides of the comb teeth, and fins are slidably connected in the T-shaped grooves. Limiting plates are installed at the top of the comb teeth to limit the position of the fins.
[0007] Furthermore, the fins are trapezoidal, and the edges of the fins are serrated.
[0008] Furthermore, the bottom plate of the collection box is inclined inward, a slot is provided on the bottom plate of the collection box, a discharge port is provided on the back of the collection box, and a cover plate is hinged to the discharge port.
[0009] Furthermore, the comb assembly is mounted on the mounting cylinder, the mounting cylinder is fitted onto the central shaft, the mounting cylinder and the central shaft are keyed together, retaining springs are provided on both sides of the mounting cylinder, and annular grooves are formed on the central shaft, with the retaining springs installed in the annular grooves.
[0010] The beneficial effects of this utility model are as follows: This utility model designs a centrifugal telescopic column component inside the comb tooth assembly. When encountering a messy Caragana korshinskii plant, the comb tooth assembly can be rotated at high speed to extend the centrifugal telescopic column. The slender and smooth telescopic column first straightens the Caragana korshinskii branches, and then the comb tooth assembly rotates at low speed to scrape off and collect the pods on the Caragana korshinskii branches, preventing excessive damage to the branches. This utility model is worth promoting and using. Attached image description:

Detailed implementation method:
[0017] like Figure 1 and Figure 2As shown, a seed collection device for Caragana korshinskii includes a horizontally arranged central shaft 1, which is rotatably connected to the inner wall of a collection box 10. Rollers 13 are installed at the bottom of the collection box 10. The central shaft 1 is connected to a motor for transmission. Several comb tooth assemblies are evenly distributed along the length of the central shaft 1. Each comb tooth assembly includes several comb tooth units evenly installed along the circumference of the central shaft 1. Each comb tooth unit includes comb teeth 2. A centrifugal telescopic column assembly is installed inside the comb teeth 2. When the central shaft 1 rotates at high speed, the centrifugal telescopic column assembly extends outward. The centrifugal telescopic column assembly is used to straighten the Caragana korshinskii branches.
[0018] like Figure 4 As shown, the centrifugal telescopic column assembly includes a telescopic column 3, a sliding column 7 connected to the bottom end of the telescopic column 3, a sliding cavity 8 provided in the comb teeth 2, a through hole opened at the top end of the comb teeth 2, the through hole communicating with the sliding cavity 8, the sliding column 7 slidably connected to the sliding cavity 8, the telescopic column 3 slidably connected to the through hole, and a compression spring 6 fitted on the telescopic column 3, the compression spring 6 contacting the sliding column 7.
[0019] like Figure 3 and Figure 5 As shown, T-shaped grooves are provided on both sides of the comb teeth 2, and fins 12 are slidably connected in the T-shaped grooves. A limiting piece 9 is installed at the top of the comb teeth 2, and the limiting piece 9 is used to limit the position of the fins 12.
[0020] To increase the friction when scraping the pods of the lemon tree, such as Figure 5 As shown, the fin 12 is trapezoidal, and the edges of the fin 12 are serrated.
[0021] like Figure 1 and Figure 2 As shown, in order to facilitate the collection of bean pods, the bottom plate of the collection box 10 is inclined inward, a slot 11 is provided on the bottom plate of the collection box 10, and a discharge port 14 is provided on the back of the collection box 10. A cover plate 15 is hinged to the discharge port 14, and a magnetic piece can be installed on the cover plate 15 to facilitate the cover plate 15 to be fixedly covered on the discharge port 14.
[0022] like Figure 4 and Figure 5 As shown, in order to facilitate the disassembly and replacement of the comb tooth assembly, the comb tooth assembly is mounted on the mounting cylinder 4, the mounting cylinder 4 is fitted onto the central shaft 1, the mounting cylinder 4 and the central shaft 1 are connected by a key, and retaining springs 5 are provided on both sides of the mounting cylinder 4. An annular groove is provided on the central shaft 1, and the retaining springs 5 are installed in the annular groove.
[0023] In practical use, such as Figures 1 to 5As shown, when pushing this utility model close to the Caragana plant, if the Caragana branches are messy, the motor can be started to rotate the central shaft 1 at high speed. Due to the centrifugal force, the telescopic column 3 extends. Due to the slender and smooth structure of the telescopic column 3, the messy Caragana branches can be straightened. Then, the motor is run at low speed and the utility model is pushed forward. At this time, the telescopic column 3 retracts due to the action of the compression spring 6, so that the Caragana branches enter between two adjacent fins 12. The fins 12 scrape the pods off the Caragana branches. The scraped pods enter the collection box 10 and are finally taken out through the discharge port 14.
[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
