Description

Technical Field

[0001] This utility model relates to the field of agricultural biotechnology, and in particular to a root tip sampling locator for seed purification. Background Technology

[0002] In the continuous development of the Chinese medicinal materials industry, the selection and breeding of superior varieties and the purification and rejuvenation of strains are core links in improving the quality and yield of Chinese medicinal materials, and their technological innovation has attracted much attention. The breeding, standardized planting or breeding, and ecological protection technologies of rare and endangered wild animal and plant medicinal species, as well as the standardized planting and breeding technologies of Chinese medicinal materials and the processing technology of Chinese medicinal materials decoction pieces, together constitute the technical support system for the high-quality development of the Chinese medicinal materials industry. Strain purification and rejuvenation play a key role in maintaining the superior characteristics of Chinese medicinal materials and preventing variety degeneration. The purity of the seed source directly affects the subsequent planting, breeding, and final quality of medicinal materials. In the process of seed source purification, the accurate sampling of the root tip of the plant is the basis for genetic identification and variety purity testing. Therefore, the root tip sampling locator for seed source purification has emerged. It can provide accurate positioning support for root tip sampling in the process of seed source purification, provide reliable technical guarantee for the purification and rejuvenation of Chinese medicinal materials, and thus promote the further development of the selection and breeding of superior varieties and standardized planting technologies of Chinese medicinal materials.

[0003] Existing material locators consist of an operating chamber and a fixing platform. They fix culture dishes containing Chinese medicinal root materials by installing a matching fixing base inside the operating chamber. However, they cannot effectively fix culture dishes of different sizes. Existing technology uses multiple micro suction cups at the bottom of the operating chamber of the material locator. By connecting a manual air pump or a small vacuum pump, the air between the suction cups and the bottom of the culture dish is extracted. Atmospheric pressure is used to firmly adsorb the culture dish containing Chinese medicinal root materials into the operating chamber. This can adsorb and fix culture dishes of different sizes. However, the suction cups themselves are made of elastic material. After long-term repeated compression and deformation, cracks or elasticity will appear, which will reduce the adhesion and sealing between them and the bottom of the culture dish, resulting in fixation failure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a root tip sampling locator for seed source purification, aiming to improve the problem in the prior art where the suction cup itself is made of elastic material, which will crack or lose elasticity after long-term repeated compression and deformation, resulting in a decrease in its adhesion and sealing to the bottom of the culture dish and thus causing fixation failure.

A threaded rod is fixedly connected to the middle of the worm wheel. The outer wall of the threaded rod is threadedly connected to the inside of the threaded block. The outer wall of the threaded rod is rotatably connected to the inside of the machine body.

[0012] As a further description of the above technical solution:

[0013] The machine body has load-bearing columns fixedly connected to the four corners of the bottom of the outer wall, and anti-slip pads are fixedly connected to the bottom of the outer walls of the multiple load-bearing columns.

Detailed Implementation

[0032] 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.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The present invention provides an embodiment of a root tip sampling locator for seed source purification, comprising a body 1, a fixing mechanism 2 fixedly connected to the right end of the body 1, the fixing mechanism 2 being used to fix culture dishes of different sizes, and a moving mechanism 3 installed inside the top of the body 1, the moving mechanism 3 being used to sample roots.

[0034] The fixing mechanism 2 includes a fixed half-ring 201, which is fixedly connected to the right end of the inside of the body 1. A movable half-ring 202 is installed on the right side of the fixed half-ring 201. A sliding groove 206 is provided at the bottom of the body 1. The bottom end of the outer wall of the movable half-ring 202 is slidably connected to the inside of the sliding groove 206. A double rack 203 is fixedly connected to the bottom of the outer wall of the movable half-ring 202. The outer wall of the double rack 203 is slidably connected to the inside of the bottom of the body 1. A support frame 204 is slidably connected to the middle of the double rack 203. The front and rear ends of the outer wall of the support frame 204 are fixedly connected to the inside of the bottom of the body 1. A drive assembly 205 is installed at the bottom of the support frame 204.

[0035] The drive assembly 205 includes a triangular knob 2051, which is installed at the bottom of the support frame 204. A rotating shaft 2052 is fixedly connected to the rear side of the outer wall of the triangular knob 2051. The outer wall of the rotating shaft 2052 is rotatably connected to the interior of the machine body 1. A double gear 2053 is fixedly connected to the rear end of the outer wall of the rotating shaft 2052. The top of the outer wall of the double gear 2053 meshes with the bottom of the outer wall of the double rack 203. The double gear 2053 is installed inside the bottom end of the machine body 1. A ratchet 2054 is fixedly connected to the front end of the outer wall of the rotating shaft 2052. The ratchet 2054 is installed on the front side of the outer wall of the machine body 1. A pawl holder 2055 is installed on the top of the outer wall of the ratchet 2054. The rear end of the outer wall of the pawl holder 2055 is rotatably connected to the front end of the outer wall of the machine body 1.

[0036] Specifically, rotating the triangular knob 2051 allows the rotating shaft 2052 welded to its rear side to rotate inside the machine body 1, thereby driving the double gear 2053 at its rear end and the ratchet 2054 at its front end to rotate. The rear end of the ratchet pawl 2055 can rotate at the front end of the machine body 1, and its cooperation with the ratchet 2054 can limit the rotation of the rotating shaft 2052. When the rotating shaft 2052 rotates, the meshing action of the double gear 2053 and the double rack 203 can cause the double rack to rotate. 203 slides in the middle of the support frame 204, which is fixed inside the machine body 1. It can support the movement of the double rack 203, thereby causing the double rack 203 to drive the moving half ring 202 to slide in the groove 206 at the bottom of the machine body 1. The fixed half ring 201 is fixed inside the machine body 1. Through the cooperation of the moving half ring 202 and the fixed half ring 201, the culture dishes of different sizes are fixed, ensuring the effective fixation of culture dishes containing Chinese medicinal root sources.

[0037] Reference Figure 3 , Figure 4 and Figure 7The moving mechanism 3 includes a material picker 301, which is installed inside the top of the machine body 1. A motor 302 is installed on the right end of the outer wall of the material picker 301. A threaded block 303 is installed on the top of the outer wall of the material picker 301. A limit groove 305 is opened at the top of the machine body 1. The inside of the limit groove 305 is slidably connected to the outer wall of the threaded block 303. A power assembly 304 is installed on the outside of the material picker 301.

[0038] The power assembly 304 includes a drive motor 3041, model 130ST-M15015. Its internal driver receives external commands (such as position pulses and speed signals) and simultaneously obtains the actual rotor state through an encoder. If there is a deviation between the actual state and the command, the driver adjusts the stator current and changes the rotational magnetic field speed or direction until the deviation is eliminated, thus achieving high-precision control. The drive motor 3041 is installed on the outside of the machine body 1. A worm 3042 is fixedly connected to the output end of the drive motor 3041. A worm wheel 3043 is installed on the top of the outer wall of the worm 3042. The top of the outer wall of the worm 3042 meshes with the bottom of the outer wall of the worm wheel 3043. A threaded rod 3044 is fixedly connected to the middle of the worm wheel 3043. The outer wall of the threaded rod 3044 is threadedly connected to the inside of the threaded block 303. The outer wall of the threaded rod 3044 is rotatably connected to the inside of the machine body 1.

[0039] Specifically, starting the drive motor 3041 causes the output end to drive the worm 3042 to rotate. Through the meshing of the worm 3042 and the worm wheel 3043, the worm wheel 3043 drives the threaded rod 3044 welded in the middle to rotate inside the machine body 1. The threaded rod 3044 is connected to the threaded block 303 through threads. Due to the rotation restriction of the limiting groove 305, when the threaded rod 3044 rotates, the threaded block 303 can only move inside the limiting groove 305 along the axial diameter of the threaded rod 3044, thereby driving the material extractor 301 to move. The motor 302 can provide material extracting power to the material extractor 301. The position of the material extractor 301 can be adjusted by controlling the switch 10 to realize the material extraction operation of the Chinese medicinal material root, ensuring accurate and efficient material extraction.

[0040] Reference Figure 1 , Figure 2 and Figure 4 The four corners of the bottom of the outer wall of the machine body 1 are fixedly connected to the load-bearing columns 4. The bottom of the outer wall of the multiple load-bearing columns 4 is fixedly connected to the anti-slip pads 5. The front side of the outer wall of the machine body 1 is fixedly connected to the protective cover 6. The ratchet 2054 is installed inside the protective cover 6. The right end of the machine body 1 is rotatably connected to the baffle 8. The right side of the outer wall of the baffle 8 is fixedly connected to the pull block 9. The front end of the machine body 1 is fixedly connected to the observation window 7. The left end of the machine body 1 is equipped with a switch 10.

[0041] Specifically, a load-bearing column 4 is installed at the bottom of the outer wall of the machine body 1, and anti-slip pads 5 are provided at the bottom to enhance the friction with the contact surface. A protective cover 6 is provided on the front side of the outer wall of the machine body 1 to protect the ratchet 2054. There is a baffle 8 at the right end of the machine body 1 and the two are rotatably connected. The baffle 8 can be opened and closed flexibly. There is a pull block 9 on the right side of the outer wall of the baffle 8 to facilitate pulling the baffle 8 and placing it into the petri dish for sampling and positioning of Chinese medicinal herbs. There is an observation window 7 at the front end of the machine body 1, through which the internal sampling process of the herb can be observed. There is a switch 10 at the left end of the machine body 1 to control the start of the machine body 1 and the rotation and sampling of the sampler 301.

[0042] Working principle: Rotating the triangular knob 2051 allows the rotating shaft 2052 welded to its rear side to rotate inside the machine body 1, thereby driving the double gear 2053 at its rear end and the ratchet 2054 at its front end to rotate. The rear end of the ratchet pawl 2055 can rotate at the front end of the machine body 1, and its cooperation with the ratchet 2054 can limit the rotation of the rotating shaft 2052. When the rotating shaft 2052 rotates, the meshing action of the double gear 2053 and the double rack 203 can cause the double rack to rotate. 203 slides in the middle of the support frame 204. The support frame 204 is fixed inside the machine body 1 and can support the movement of the double rack 203. In turn, the double rack 203 drives the moving half ring 202 to slide in the sliding groove 206 at the bottom of the machine body 1. The fixed half ring 201 is fixed inside the machine body 1. Through the cooperation of the moving half ring 202 and the fixed half ring 201, the fixation of culture dishes of different sizes can be achieved, ensuring the effective fixation of culture dishes containing Chinese medicinal root sources.

[0043] When the drive motor 3041 is started, its output end can drive the worm 3042 to rotate. Through the meshing of the worm 3042 and the worm wheel 3043, the worm wheel 3043 drives the threaded rod 3044 welded in the middle to rotate inside the machine body 1. The threaded rod 3044 is connected to the threaded block 303 through threads. Due to the rotation restriction of the limiting groove 305, when the threaded rod 3044 rotates, the threaded block 303 can only move inside the limiting groove 305 along the axial diameter of the threaded rod 3044, thereby driving the material extractor 301 to move. The motor 302 can provide material extracting power to the material extractor 301. The position of the material extractor 301 can be adjusted by controlling the switch 10 to realize the material extraction operation of the Chinese medicinal material root, ensuring accurate and efficient material extraction.
