Description

Technical Field

[0001] This invention relates to the field of soil sampling technology, and in particular to a soil sample collection device for arable land quality surveys. Background Technology

[0002] When conducting soil quality testing on arable land, it is necessary to take samples from the ground, extract soil from different locations, and test them to determine whether the arable land is suitable. The conventional method of soil sampling is to use various drill rods to break up the ground, then collect the soil into a sampling device, and after the soil is removed, it can be used for subsequent testing.

[0003] The currently used data acquisition devices have the following drawbacks:

[0004] 1. The integrated drill rod structure is used for data collection. The drill rod bears high pressure, which affects the collection efficiency. At the same time, it lacks a convenient manual control feed transmission function. Soil is extracted and collected during the drilling process.

[0005] 2. Lacks auxiliary functions for transporting and collecting soil to control its flow direction;

[0006] 3. Soil is mainly collected through centralized containment structures, but there is a lack of containment structures that can be quickly switched, making it inconvenient to collect samples from multiple locations. Summary of the Invention

[0007] In view of the above, the present invention addresses the shortcomings of the prior art by providing a soil sample collection device for arable land quality survey.

[0008] This invention provides a soil sample collection device for arable land quality surveys, specifically comprising: a collection cylinder, wherein a bottom support ring is fixedly installed at the bottom of the collection cylinder, and a plastic annular airbag is fixedly installed at the bottom of the bottom support ring; a transmission chamber is integrally installed in the middle of the top of the collection cylinder, and a transmission sleeve is rotatably installed in the transmission chamber in conjunction with a bearing, and a hexagonal shaft is slidably installed in the middle of the transmission sleeve; a screw propeller is fixedly installed at the bottom end of the hexagonal shaft; two sets of bearing seats are fixedly installed on the outside of the collection cylinder, and a rotating frame ring is rotatably installed outside the bearing seats in conjunction with the bearing, and six sets of L-shaped frames are integrally installed on the outside of the rotating frame ring; two sets of bearing rings are fixedly installed on the outside of each L-shaped frame, and a receiving bottle can be installed in the bearing ring, and the L-shaped frame can support the bottom of the receiving bottle; a handle-type connecting pipe is fixedly installed at one end of the transmission chamber; a separator, wherein a Y-shaped ventilation frame is fixedly connected to one side of the separator, and the two branches of the Y-shaped ventilation frame are fixedly connected to the top of the collection cylinder; and a vacuum pump is connected to the top of the separator.

[0009] Optionally, a ventilation bend is provided around the bottom support ring, which connects the inner and outer sides of the collection cylinder.

[0010] Optionally, the top end of the hexagonal shaft is rotatably provided with a rotating plate in conjunction with a bearing; the top end of the hexagonal shaft is integrally provided with a flange structure, and a spring is sleeved on the hexagonal shaft, with the spring located between the flange structure and the transmission sleeve.

[0011] Optionally, the bottom of the propeller is integrally provided with two sets of side drilling frames. The main body of the side drilling frames is an elliptical rod structure, and the bottom of each side drilling frame is integrally provided with soil-turning spikes that are distributed at equal intervals in an inclined manner. The bottom of the side drilling frames is higher than the bottom of the propeller's spiral structure.

[0012] Optionally, a linkage shaft is rotatably mounted on the intermediate mating bearing of the handle-type connecting tube, and the linkage shaft is connected to the transmission sleeve by a bevel gear transmission; a drive motor is fixedly mounted on the outside of the handle-type connecting tube, and the drive motor is connected to the linkage shaft by transmission.

[0013] Optionally, a side handle is fixedly provided on one side of the collection cylinder, and a control button is also provided at the installation location of the side handle. An aluminum tube is provided outside the control button to connect the drive motor and the air pump, and a power supply and control connection wire is provided inside the aluminum tube.

[0014] Optionally, the separator is integrally provided with an inclined guide plate, the end of the inclined guide plate away from the Y-shaped vent frame is inclined downward; an intercepting net is fixedly provided between the inner wall of the separator away from the Y-shaped vent frame and the top of the inclined guide plate.

[0015] Optionally, the bottom of the separator is fixedly provided with an outer ring, and the outer ring has an integrally provided flange structure on the outer side of its bottom. A bottle mouth cover is slidably provided on the outside of the outer ring. A spring is sleeved on the outside of the outer ring, and the spring is located on the top of the bottle mouth cover. The top of the receiving bottle has an integrally provided cylindrical bottle mouth structure that protrudes upwards, and the bottle mouth cover can fit and fasten to the outside of the bottle mouth structure of the receiving bottle.

[0016] Optionally, a barrier net for blocking stones is provided at the external through hole of the ventilation bend and at the connection between the Y-shaped ventilation frame and the collection cylinder.

[0017] The beneficial effects are as follows:

[0018] 1. This invention is equipped with a spiral propeller, which provides a highly efficient drilling function. When the spiral propeller is rotating, the rotating blades can be manually pressed down to push the spiral propeller downward during the rotation process. The soil-turning spikes first contact the ground to break up the soil surface, and then the spiral structure of the spiral propeller transports the soil upward, which enhances the drilling effect and ensures a stable transmission effect during drilling.

[0019] 2. A separator is installed to help control the flow of soil. An air pump is used to extract air, which generates airflow to guide the flow of soil. Air enters the collection cylinder from the outside to the inside through the ventilation bend, then passes through the Y-shaped ventilation frame and enters the separator. After being intercepted by the interception net, it passes through the air pump and is discharged to the outside, forming a circulating flow effect. After the soil enters the separator, it is discharged into the collection bottle for collection.

[0020] 3. A rotating frame ring is provided, which allows for quick switching of the receiving structure. Lifting the bottle neck cover upwards causes it to detach from the bottle neck structure of the receiving bottle, unlocking the receiving bottle. Then, rotating the receiving bottle and the L-shaped frame allows for switching the receiving bottle. Moving another set of receiving bottles under the bottle neck cover and releasing the bottle neck cover causes it to automatically snap onto the outside of the bottle neck structure of the new receiving bottle with the help of a spring, thus achieving connection and fixing the position of the receiving bottle.

[0032] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0033] Example 1: Please refer to the accompanying drawings in the instruction manual. Figures 1 to 9 As shown:

[0034] This invention proposes a soil sample collection device for arable land quality surveys, comprising: a collection cylinder 1, a bottom support ring 2 fixedly mounted at the bottom of the collection cylinder 1, and a plastic annular airbag 201 fixedly mounted at the bottom of the bottom support ring 2; a transmission chamber 103 integrally mounted in the middle of the top of the collection cylinder 1, a transmission sleeve 3 rotatably mounted in the transmission chamber 103 in conjunction with a bearing, and a hexagonal shaft 301 slidably mounted in the middle of the transmission sleeve 3; a screw propeller 4 fixedly mounted at the bottom end of the hexagonal shaft 301; and two sets of bearing seats 101 fixedly mounted on the outside of the collection cylinder 1. The 101 external bearing is rotatably equipped with a rotating frame ring 5, and six sets of L-shaped frames 501 are integrally installed on the outside of the rotating frame ring 5; two sets of bearing rings 502 are fixedly installed on the outside of each L-shaped frame 501, and the receiving bottle 6 can be installed in the bearing ring 502. The L-shaped frame 501 can support the bottom of the receiving bottle 6; a handle-type connecting pipe 7 is fixedly installed at one end of the transmission chamber 103; a separator 8 is fixedly connected to one side of the separator 8 with a Y-shaped venting frame 801, and the two branches of the Y-shaped venting frame 801 are fixedly connected to the top of the collection cylinder 1; a vacuum pump 9 is connected to the top of the separator 8.

[0035] The bottom support ring 2 has a ventilation bend 202 that connects the inner and outer sides of the collection cylinder 1.

[0036] Among them, the top end of the hexagonal shaft 301 is rotatably equipped with a rotating plate 302 in conjunction with the bearing; the top end of the hexagonal shaft 301 is integrally provided with a flange structure, and a spring is sleeved on the hexagonal shaft 301, with the spring located between the flange structure and the transmission rotating sleeve 3.

[0037] Among them, the bottom end of the spiral propeller 4 is integrally provided with two sets of side drilling frames 401. The main body of the side drilling frame 401 is an elliptical rod structure. The bottom of the side drilling frame 401 is integrally provided with soil turning spikes 402 that are distributed at equal intervals in an inclined shape. The bottom of the side drilling frame 401 is higher than the bottom end of the spiral structure of the spiral propeller 4.

[0038] Among them, the handle-type connecting tube 7 is rotatably mounted with a bearing in the middle, and the linkage shaft 701 is connected to the transmission sleeve 3 by bevel gear transmission; the handle-type connecting tube 7 is externally fixed with a drive motor 702, and the drive motor 702 is connected to the linkage shaft 701 by transmission.

[0039] The collection cylinder 1 has a side handle 102 fixedly installed on one side. A control button is also installed at the installation location of the side handle 102. An aluminum tube is installed outside the control button to connect the drive motor 702 and the air pump 9. A power supply and control connection wire is installed inside the aluminum tube.

[0040] The separator 8 has an integrally integrated inclined guide plate 802 inside, with the end of the inclined guide plate 802 away from the Y-shaped vent frame 801 tilted downwards; an intercepting net 803 is fixedly installed between the inner wall of the separator 8 away from the Y-shaped vent frame 801 and the top of the inclined guide plate 802.

[0041] The separator 8 has an outer ring 804 fixedly installed at its bottom. The outer ring 804 has an integral flange structure on its bottom outer side. A bottle mouth cover 805 is slidably installed on the outside of the outer ring 804. A spring is sleeved on the outside of the outer ring 804 and is located on the top of the bottle mouth cover 805. The top of the receiving bottle 6 has an integrally installed cylindrical bottle mouth structure that protrudes upwards. The bottle mouth cover 805 can fit and fasten to the outside of the bottle mouth structure of the receiving bottle 6.

[0042] like Figure 1-9 As shown, when in use, the handle-type connecting tube 7 is used as the main grip and the side grip 102 is used as the auxiliary control; the annular airbag 201 is manually placed on the ground, and the collection tube 1 is sealed to the ground by the adaptive effect of the annular airbag 201; at this time, the ventilation bend 202 can be connected by gas.

[0043] During operation, the device is driven by either wired power supply or stored electricity supply as needed. The drive motor 702 is started to drive the linkage shaft 701 to rotate. The linkage shaft 701, in conjunction with the bevel gear, drives the transmission sleeve 3 to rotate. The transmission sleeve 3 drives the hexagonal shaft 301 to rotate. The hexagonal shaft 301 can drive the screw propeller 4 to rotate continuously.

[0044] When the screw propeller 4 is rotating, manually press down on the rotating blade 302. The rotating blade 302 can be used to push the screw propeller 4 downward during the rotation process. The soil turning spike 402 first contacts the ground and breaks up the soil surface. Then, the soil is transported upward through the screw structure of the screw propeller 4.

[0045] At the same time, the air pump 9 is started to extract air. The air enters the collection cylinder 1 from the outside to the inside through the ventilation bend 202, then enters the separator 8 through the Y-shaped ventilation frame 801, and after being intercepted by the interception net 803, it passes through the air pump 9 and is discharged to the outside, forming a circulating flow effect.

[0046] During this process, the pulverized soil will rise with the airflow and enter the separator 8. After entering the separator 8, the soil will be intercepted by the interception net 803 and will not be able to be discharged to the outside. Instead, it will be discharged from the outer ring 804 at the bottom of the separator 8 into the collection bottle 6 for collection.

[0047] Example 2: Based on Example 1, the material and thickness of the interception net 803 can be customized as needed. The proportion can be adjusted according to the size of the collection device to ensure successful soil collection.

[0048] In addition, a barrier net for blocking stones is provided at the external through hole of the ventilation bend 202 and at the connection between the Y-shaped ventilation frame 801 and the collection cylinder 1. The material and size of the barrier net can be adjusted as needed, and it is optional to install it.

[0049] Example 3: Based on Example 1, after collecting a soil sample from one location, the bottle neck slide cover 805 can be lifted upwards to detach it from the bottle neck structure of the receiving bottle 6. At this time, the receiving bottle 6 is unlocked, and then the receiving bottle 6 and the L-shaped frame 501 are rotated to switch the receiving bottle 6. The other set of receiving bottles 6 is moved below the bottle neck slide cover 805. The bottle neck slide cover 805 is released, and the bottle neck slide cover 805 automatically snaps onto the outside of the bottle neck structure of the new receiving bottle 6 with the help of the spring, thus achieving fixation.

[0050] The specific usage and function of this embodiment: In this invention, during collection, the handle-type connecting tube 7 is used as the main handle, and the annular airbag 201 is placed on the ground. The adaptive effect of the annular airbag 201 is used to seal the collection tube 1 with the ground; at this time, the ventilation bend 202 can be connected by gas.

[0051] The drive motor 702 is started to drive the linkage shaft 701 to rotate. The linkage shaft 701, in conjunction with the bevel gear, drives the transmission sleeve 3 to rotate. The transmission sleeve 3 drives the hexagonal shaft 301 to rotate. The hexagonal shaft 301 can drive the screw propeller 4 to rotate continuously. When the screw propeller 4 is rotating, the rotating vane 302 is manually pressed down. The rotating vane 302 can be used to push the screw propeller 4 downward during the rotation process. The soil-turning spike 402 first contacts the ground to break up the soil surface, and then the soil is transported upward through the spiral structure of the screw propeller 4.

[0052] The air pump 9 is activated to extract air. Air enters the collection cylinder 1 from the outside to the inside through the ventilation bend 202, then passes through the Y-shaped ventilation frame 801 and enters the separator 8. After being intercepted by the intercepting net 803, it passes through the air pump 9 and is discharged to the outside, forming a circulating flow effect. During this process, the crushed soil will also rise with the airflow and enter the separator 8. After entering the separator 8, the soil is intercepted by the intercepting net 803 and cannot be discharged to the outside. Instead, it is discharged from the outer ring 804 at the bottom of the separator 8 into the collection bottle 6 for collection.

[0053] After completing the collection and filling of a set of containment bottles 6, lift the bottle neck slide 805 upwards so that the bottle neck slide 805 is disengaged from the bottle neck structure of containment bottle 6, unlock containment bottle 6, and then rotate containment bottle 6 and L-shaped bracket 501 to switch containment bottles 6. Move another set of containment bottles 6 under the bottle neck slide 805, release the bottle neck slide 805, and the bottle neck slide 805 will automatically snap onto the outside of the bottle neck structure of the new containment bottle 6 with the help of springs, thus achieving fixation.

[0054] The pre-filled containment bottle 6 can be taken out directly after switching, sealed, and then stored for subsequent testing.
