A separator for collecting paddy rhizosphere soil under waterlogged conditions

Abstract

This invention belongs to the technical field of rhizosphere soil collectors, and specifically relates to a collector for separating and collecting rhizosphere soil from rice plants under flooded conditions. The collector includes a main frame; a central rod with an outer frame slidably mounted on its outer side; a swing block rotatably mounted on the lower part of the outer frame; toothed grooves along the outer edge of the swing block; and a support rod at the end of the swing block; a shovel frame connected to the lower part of the support rod, with the shovel frames converging at the bottom and dispersing at the top; and an inner frame fitted around the outer side of the central rod at the center of the outer frame, with toothed plates on its outer surface that mesh with the toothed grooves of the swing block. By configuring the shovel frames, with the bottom converging and the top dispersing, the rice plants can be scooped up from the roots along with the soil around them, while the top dispersing allows for direct removal of the upper clay layer. The soil can then be moved to a dry location to unfold the bottom and peel off the drier lower soil layer, making it easier to obtain more rhizosphere soil.

Description

Technical Field

[0001] This invention relates to the field of rhizosphere soil collectors, and more particularly to a separator and collector for rice rhizosphere soil under flooded conditions. Background Technology

[0002] Rhizosphere soil refers to the soil within the rhizosphere region. The rhizosphere is a micro-region of soil that differs from the main soil mass in physical, chemical, and biological properties due to the influence of plant root activity. The rhizosphere is very small, generally referring to the area within a few millimeters of the root axis surface.

[0003] When sampling the rhizosphere soil of rice in a flooded state, the soil may be washed away by the water in the paddy field. When sampling by digging, the clay with high surface moisture content tends to stick to the rice roots, and the rhizosphere soil may be lost during the peeling process. To address these issues, we propose a rhizosphere soil separator for rice in a flooded state. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a separation and collection device for rice rhizosphere soil under flooded conditions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A separator for collecting rhizosphere soil from rice plants under flooded conditions, comprising a main frame;

[0007] A central pole, an outer frame is slidably installed on the outside of the central pole, a swing block is rotatably installed on the lower part of the outer frame, a toothed groove is opened on the outer edge of the swing block, and a support rod is installed at the end of the swing block;

[0008] The shovel frame is connected to the lower part of the support rod, with the shovel frames converging at the bottom and dispersing at the top.

[0009] The inner frame is fitted outside the middle rod and located in the middle of the outer frame. The outer surface of the inner frame is fitted with a toothed plate that meshes with the tooth groove of the swing block.

[0010] Preferably, the main frame is designed in the shape of a gantry frame, with a pin rod installed through the middle of the main frame, and vertically arranged pin holes opened on the upper part of the middle rod.

[0011] Preferably, a vertically conductive cover is provided in the middle of the main frame, and the cover is fitted and installed on the outside of the shovel frame.

[0012] Preferably, the inner diameter of the cover does not affect the swing opening of the shovel frame, and the top edge of the cover extends beyond the upper part of the outer frame.

[0013] Preferably, the outer surface of the outer frame is fixed with a vertical frame, and a ring frame is installed at the bottom of the vertical frame. The ring frame is rotatably connected to the swing block, and the distance between the ring frame and the outer frame is consistent with the height of the toothed plate.

[0014] Preferably, the lower part of the swing block extends out with a support lug, and a base is fixedly installed on the upper edge of the shovel frame. The support lug and the support rod, and the support rod and the base are respectively fixedly connected by bolts.

[0015] Preferably, the shovel frame adopts an isosceles triangular shape, has a horizontal end face, and has a beveled blade on the lower side wall.

[0016] Preferably, a top ring is installed at the top of the inner frame, and a base frame is provided at the bottom of the inner frame. The top ring is located between the outer frame and the ring frame, and the base frame is located below the ring frame.

[0017] Preferably, a limiting block is installed at the bottom of the vertical frame facing the center rod, and a protrusion that cooperates with the limiting block is installed on the outer surface of the inner frame.

[0018] Preferably, the inner frame is slidably sleeved on the outside of the middle rod, and a spring is installed at the bottom of the middle rod below the inner frame. A boss is provided on the upper outer surface of the spring, an end block is installed at the bottom of the spring, and a notch is provided between the springs. The spring adopts a shape that is thinner at the top and thicker at the bottom.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] 1. By setting up the shovel frame, with the bottom close together and the top dispersed, the bottom close together can shovel up the rice from the root and the soil together, and the top dispersed can directly remove the upper layer of clay from the top. Then move it to a dry position and spread the bottom to peel off the lower layer of drier soil, which can more easily obtain more rhizosphere soil.

[0021] 2. With the central pole in place, it can be erected vertically to fix the shovel frame at the sampling position for easy sampling. After sampling, the plant stem can be inserted between the spring clips at the lower end of the central pole. The central pole can be pressed down to retract the spring clips and fix the plant. When the shovel frame is extended to remove soil, the plant can be fixed, the central pole can be removed, and the soil can be quickly knocked off by swinging the central pole. The operation is convenient. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1

[0033] Reference Figure 1-4 This embodiment provides a rice rhizosphere soil separation and collection device under flooded conditions, the main body of which includes a main frame 1, a middle rod 11 and a shovel frame 2.

[0034] Regarding the middle rod 11, an outer frame 4 is slidably installed on the outside of the middle rod 11. The outer frame 4 can be driven to slide up and down on the outside of the middle rod 11. A swing block 41 is rotatably installed on the lower part of the outer frame 4. A toothed groove is opened on the outer edge of the swing block 41. A support rod 21 is installed at the end of the swing block 41. Regarding the inner frame 5, the inner frame 5 is sleeved on the outside of the middle rod 11 and located in the middle of the outer frame 4. A toothed plate 51 that meshes with the toothed groove of the swing block 41 is installed on the outer surface of the inner frame 5. When the outer frame 4 drives the swing block 41 to move up and down, the swing block 41 can rotate by meshing with the toothed plate 51, thereby driving the support rod 21 to be lifted. Pushing down the outer frame 4 can lower the support rod 21.

[0035] Regarding the shovel frame 2, the shovel frame 2 is connected to the lower part of the support rod 21. The bottom of the shovel frames 2 are gathered together and the top is dispersed. When the support rod 21 is raised, the shovel frame 2 is raised synchronously, thus reaching the ready state. Pressing down and adding 4 can press down the shovel frame 2, so that the bottom of the shovel frames 2 are gathered together, and the plant along with the soil is shoveled up synchronously.

[0036] The outer frame 4 slides outside the middle rod 11, cooperating with the inner frame 5 to drive the shovel frame 2 to open and close for sampling. The following, with reference to the diagram, further explains the related components:

[0037] First, refer to Figure 1The main frame 1 is designed in the shape of a gantry frame. A pin is installed through the middle of the main frame 1. The upper part of the middle rod 11 has vertically arranged pin holes, which can fix the middle rod 11 during sampling. After sampling, the middle rod 11 and the sample are removed from the paddy field together.

[0038] Furthermore, a vertically conductive cover 3 is set in the middle of the main frame 1. The cover 3 is fitted and installed on the outside of the shovel frame 2. For easy positioning, the cover 3 is placed on the outside of the plant. After inserting it into the soil, water can be drained and then samples can be taken. At this time, the sample taken out by the closed shovel frame 2 does not contain water, which makes it easier to first dig out the surface clay from the top of the shovel frame 2, and then unfold the shovel frame 2 to shake out the soil, which facilitates the separation of the plant.

[0039] Furthermore, the inner diameter of the cover 3 does not affect the swinging and opening of the shovel frame 2, ensuring that the display frame 2 can be unfolded for preparation and retracted for sampling. The top edge of the cover 3 extends beyond the upper part of the outer frame 4, effectively separating the paddy field water.

[0040] Example 2

[0041] Reference Figure 1-3 This embodiment provides a rice rhizosphere soil separation and collection device under flooded conditions, the main body of which includes a main frame 1, a middle rod 11 and a shovel frame 2.

[0042] Example 2 differs from Example 1 mainly in the structural improvement of the shovel frame 2; the other structures and principles remain completely the same. The specific configuration of the shovel frame 2 is explained below:

[0043] First, a vertical frame 42 is fixed on the outer surface of the outer frame 4. A ring frame 422 is installed at the bottom of the vertical frame 42. The ring frame 422 is rotatably connected to the swing block 41. The distance between the ring frame 422 and the outer frame 4 is consistent with the height of the toothed plate 51, so as to make full use of the height of the toothed plate 51 and ensure that the swing block 41 can swing fully, so that the shovel frame 2 can open and close fully.

[0044] Furthermore, the lower part of the shovel block 41 extends out a support ear 411, and a base 22 is fixedly installed on the upper edge of the shovel frame 2. The support ear 411 and the support rod 21, and the support rod 21 and the base 22 are respectively fixedly connected by bolts. In order to adapt to the plant roots at different depths, the bolts can be loosened to adjust the tilt angle of the shovel frame 2, thereby adjusting the sampling depth and avoiding taking out too much soil to affect the subsequent separation of rhizosphere soil.

[0045] Furthermore, the shovel frame 2 adopts an isosceles triangular shape, with a horizontal end face and the pointed corner of the shovel frame 2 pointing downwards. The lower side wall of the shovel frame 2 is equipped with a slanted blade to facilitate shoveling into the soil for easy sampling.

[0046] Example 3

[0047] Reference Figure 1-5This embodiment provides a rice rhizosphere soil separation and collection device under flooded conditions, the main body of which includes a main frame 1, a middle rod 11 and a shovel frame 2.

[0048] Example 3 differs from Example 1 mainly in the structural improvement of the inner frame 5; the other structures and principles remain completely the same. The specific configuration of the inner frame 5 is explained below:

[0049] First, a top ring 52 is installed on the top of the inner frame 5, and a base frame 54 is set at the bottom of the inner frame 5. The top ring 52 is located between the outer frame 4 and the ring frame 422, and the base frame 54 is located below the ring frame 422. The inner frame 5 slides between the outer frame 4, which can stably prevent the inner frame 5 and the outer frame 4 from separating, and the structure is stable.

[0050] Furthermore, a limiting block 421 is installed on the bottom of the vertical frame 42 facing the middle rod 11, and a protrusion 53 that cooperates with the limiting block 421 is installed on the outer surface of the inner frame 5. The limiting block 421 can slide with the protrusion 53, which can achieve vertical stability between the inner frame 5 and the outer frame 4.

[0051] Furthermore, the inner frame 5 is slidably sleeved on the outside of the middle rod 11. The bottom of the middle rod 11 is located below the inner frame 5 and a spring piece 12 is installed. The upper outer surface of the spring piece 12 is provided with a boss 121, and the bottom of the spring piece 12 is provided with an end block 122. A notch 123 is provided between the spring pieces 12. The spring piece 12 adopts a shape that is thinner at the top and thicker at the bottom. In order to quickly separate the plant and most of the soil, the inner frame 5 can be moved down to pass over the boss 121, and then the spring piece 12 is squeezed to make the end blocks 122 come together. At this time, the plant mixed between the spring pieces 12 is fixed, and the outer frame 4 can be driven down to open the shovel frame 2. By shaking, the soil at the roots of the plant can be quickly shaken off, making the operation convenient.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
