Description
Technical Field
[0001] The utility model relates to the technical field of land sample collection, in particular to a land sample collection collector. Background Art
[0002] The collection and processing of soil samples is an important part of soil analysis, which is directly related to the correctness of the analysis results. Therefore, soil samples must be collected and processed in the correct way to obtain analysis results that conform to reality. A land sample collector is a tool for collecting soil samples. It can help farmers, agricultural researchers and land managers to quickly and accurately collect soil samples for soil analysis and evaluation. For some land sample collectors, the upper end of the collection tube of the device is fixedly connected with a collection shell by bolts. When collecting soil samples, the staff holds the handle so that the collection tube of the land sample collector is connected to the The land is aligned vertically, and then the collection tube is vibrated by a vibrator so that the device can penetrate into the land. When the collection tube penetrates into a designated position inside the land, the spiral feed sheet in the collection tube is rotated by a control unit, and the lower end of the collection tube is moved up along its own inner wall to the collection shell at the upper end of the device through the spiral surface. However, the device uses a vibrator to make the collection tube penetrate into the land. The vibrator itself is affected by the output power and has a large volume, which greatly increases the overall weight of the device, does not move, and increases the production cost of the device. At the same time, after each soil sampling and collection by the device, the collection shell needs to be replaced in advance for the next use, and the operation is more cumbersome. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a soil sample collection collector. The device uses spiral torque through a fixed element to make the soil sample collection part penetrate deep into the soil. No electrical components are required. The device itself is light in weight and low in cost. At the same time, multiple collection tubes are installed on the upper end of the device, which can be opened and closed separately according to the needs of soil sample collection. There is no need to frequently replace the collection tubes, which can effectively solve the problems in the background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a land sample collection collector, comprising a handheld frame and a conversion adjustment mechanism;
[0005] Hand-held frame: a threaded sampling cylinder is provided in the middle of the bottom wall, a conversion shell is provided at the upper end of the threaded sampling cylinder, a connection tube evenly distributed is penetrated through the upper end of the inner wall of the conversion shell, a collection cylinder is sleeved on the outer side of the other end of the connection tube, a rotating shaft is rotatably connected to the top wall of the conversion shell through a bearing, a spiral material sheet is provided at the lower end of the outer side of the rotating shaft, the rotating shaft and the spiral material sheet are both installed in conjunction with the threaded sampling cylinder, and handles are provided on both sides of the hand-held frame;
[0006] Conversion and adjustment mechanism: They are all arranged inside the connecting pipe. The device uses spiral torque through fixed elements to make the soil sample collection site deep into the soil. No electrical components are required. The device itself is light in weight and low in cost. At the same time, multiple collection cylinders are installed on the upper end of the device, which can be opened and closed separately according to the soil sample collection needs, without the need to frequently replace the collection cylinders.
[0007] Furthermore, a hollow drill bit is provided at the bottom of the threaded sampling tube, so that the lower end of the threaded sampling tube can spirally penetrate into the soil.
[0008] Furthermore, the conversion and adjustment mechanism includes a closing door, an arc-shaped telescopic column and a spring. The closing door is evenly hinged to the inside of the connecting tube through a hinge. An arc-shaped telescopic column and a spring are provided between the closing door and the adjacent connecting tube. The springs are movably sleeved with the outer ends of the adjacent arc-shaped telescopic columns. The arc centers of the fixed end and the telescopic end of the arc-shaped telescopic column coincide with the axis centers of the adjacent hinges. A plurality of collecting tubes are installed at the upper end, which can be opened and closed individually according to the needs of soil sample collection, without the need to frequently replace the collecting tubes.
[0009] Furthermore, the conversion and adjustment mechanism also includes locking bolts, which are evenly threadedly connected to the outside of the connecting pipe. The outside of the closing door is provided with locking grooves, and the locking bolts are plugged into adjacent locking grooves to limit the flipping of the closing door to prevent the connecting pipes corresponding to the remaining collecting tubes from opening under the action of soil squeezing force when transporting soil samples to a certain collecting tube.
[0010] Furthermore, the conversion and adjustment mechanism also includes limit rods, which are evenly arranged inside the connecting tube. The limit rods are installed in cooperation with adjacent closing doors to limit the elastic reset stroke after the closing doors are opened, thereby preventing the two closing doors from failing to close the corresponding connecting tubes.
[0011] Furthermore, the upper end of the rotating shaft passes through the top wall of the handheld frame and is provided with a rotating disk, which is convenient for applying a rotational force to the rotating shaft so that the soil sample at the bottom of the device moves up along the inner wall of the threaded sampling tube.
[0012] Furthermore, the outer side of the threaded sampling tube is threadedly connected to a fixing seat, the outer side of the fixing seat is provided with evenly distributed connecting seats, and the lower side of the connecting seats is provided with evenly distributed ground gripping nails, so that the land sample collection collector is vertically limited to the ground to avoid subsequent soil sample collection.
[0013] Compared with the prior art, the beneficial effects of the utility model are: the land sample collection collector has the following advantages:
[0014] 1. When collecting soil samples, first move the device to the specified position through the handheld frame, then contact the lower side of the connecting seat with the ground, and then the staff presses down the connecting seat with both feet to make the gripping nails penetrate into the soil, thereby fixing the entire device to the ground, and then rotate the handheld frame forward by the handle to make the threaded sampling tube drive the hollow drill bit to rotate forward. During the forward rotation of the threaded sampling tube, it is threadedly connected with the fixing seat so that its lower end rotates through the hollow drill bit to penetrate into the soil, and the spiral torque is used to make the soil sample collection part of the device penetrate into the soil. The land sample collection collector uses spiral torque through the fixing element to make the soil sample collection part penetrate into the soil, no electrical components are required, the device itself is light in weight, and the cost is low.
[0015] 2. The spiral loading sheet rotates so that the soil sample at the bottom of the device moves vertically upward along the inner wall of the threaded sampling tube. At the same time, the corresponding locking stud is rotated to move it away from the locking groove, thereby releasing the flip limit of the closed door corresponding to the collection tube at this time. When the soil samples in the conversion shell gather to a certain extent, the contact pressure between the soil samples causes the unlocked closed door to flip open around the corresponding hinge, and the fixed end and the spring of the arc-shaped telescopic column contract, thereby opening the corresponding connecting pipe. Then the soil sample enters the corresponding collection tube through the connecting pipe. After the device collects the soil sample, it moves out of the land. The corresponding closed door is reversed and reset around the hinge by the compression elastic force of the spring. The reverse reset stroke of the closed door is limited by tightening the limit rod, so that the corresponding two closed doors cooperate to block the corresponding connecting pipe. When the next soil sample is collected, the locking limit of the locking bolt of another collection tube is released by the same principle. The land sample collection collector is equipped with multiple collection tubes at the upper end, which can be opened and closed separately according to the soil sample collection needs, without the need to frequently replace the collection tubes.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 , This embodiment provides a technical solution: a land sample collection collector, including a handheld frame 1 and a conversion adjustment mechanism 7;
[0023] Hand-held frame 1: A threaded sampling tube 2 is provided in the middle of its bottom wall, a conversion shell 4 is provided at the upper end of the threaded sampling tube 2, a connecting tube 5 evenly distributed is penetrated through the upper end of the inner wall of the conversion shell 4, and a collecting tube 6 is sleeved on the outer side of the other end of the connecting tube 5, and a rotating shaft 8 is rotatably connected to the top wall of the conversion shell 4 through a bearing, and a spiral upper material piece 9 is provided at the lower end of the outer side of the rotating shaft 8, and the rotating shaft 8 and the spiral upper material piece 9 are both installed in cooperation with the threaded sampling tube 2, and handles 11 are provided on the left and right sides of the hand-held frame 1, a hollow drill bit 3 is provided at the bottom of the threaded sampling tube 2, and the upper end of the rotating shaft 8 passes through the hand-held The top wall of the frame 1 is provided with a turntable 10, and the outer side of the threaded sampling tube 2 is threadedly connected with a fixing seat 12, and the outer side of the fixing seat 12 is provided with evenly distributed connecting seats 13, and the lower side of the connecting seat 13 is provided with evenly distributed ground-grasping spikes 14. When collecting soil samples, the device is first moved to a designated position by the handheld frame 1, and then the lower side of the connecting seat 13 is brought into contact with the ground. Then, the staff presses down the connecting seat 13 with both feet to make the ground-grasping spikes 14 penetrate into the soil, thereby fixing the entire device to the ground, and then the handle 11 is turned forward to the handheld The frame 1 allows the threaded sampling tube 2 to drive the hollow drill bit 3 to rotate forward. During the forward rotation of the threaded sampling tube 2, the threaded connection with the fixing seat 12 allows the lower end of the threaded sampling tube 2 to rotate through the hollow drill bit 3 to penetrate into the soil. The spiral torsion force is used to make the soil sample collection part of the device penetrate into the soil. The operation is convenient and the preparation cost is low. During this process, the spiral direction of the spiral upper material piece 9 is opposite to the direction of the thread groove of the threaded sampling tube 2, thereby preventing the spiral upper material piece 9 from driving the soil to move upward along the inner wall of the threaded sampling tube 2 during the forward rotation of the threaded sampling tube 2 to penetrate into the soil. When the lower end of the threaded sampling tube 2 penetrates into the corresponding soil collection part in the soil, the turntable 10 is then rotated in the reverse direction to drive the spiral upper material piece 9 to rotate through the rotating shaft 8. As the lower end of the threaded sampling tube 2 continues to penetrate into the soil, the spiral upper material piece 9 rotates to make the soil sample at the bottom of the device move vertically along the inner wall of the threaded sampling tube 2 to the corresponding collecting tube 6. The soil sample collection collector uses the spiral torsion force through the fixing element to make the soil sample collection part penetrate into the soil. No electrical components are required, the device itself is light in weight, and the cost is low.
[0024] Conversion adjustment mechanism 7: It is arranged inside the connecting tube 5. The conversion adjustment mechanism 7 includes a closing door 71, an arc-shaped telescopic column 72 and a spring 73. The closing door 71 is evenly hinged to the inside of the connecting tube 5 through a hinge. An arc-shaped telescopic column 72 and a spring 73 are arranged between the closing door 71 and the adjacent connecting tube 5. The spring 73 is movably connected to the outer end of the adjacent arc-shaped telescopic column 72. The arc centers of the fixed end and the telescopic end of the arc-shaped telescopic column 72 coincide with the axis center of the adjacent hinge. The conversion adjustment mechanism 7 also includes a locking bolt 75. The locking bolt 75 are evenly threadedly connected to the outside of the connecting pipe 5, and locking grooves are provided on the outside of the closing door 71. The locking bolts 75 are plugged into the adjacent locking grooves. The conversion adjustment mechanism 7 also includes a limit rod 74, which is evenly arranged inside the connecting pipe 5. The limit rod 74 is installed in cooperation with the adjacent closing door 71. When collecting soil samples, the corresponding locking stud 75 is rotated to keep it away from the locking groove, thereby releasing the flip limit of the closing door 71 corresponding to the collection tube 6 at this time. When the soil sample in the conversion shell 4 is accumulated to a certain extent, Through the contact pressure between the soil samples, the unlocked closed door 71 is flipped open around the corresponding hinge, and the fixed end of the arc-shaped telescopic column 72 and the spring 73 are contracted, so that the corresponding connecting tube 5 is opened, and then the soil sample enters the corresponding collecting tube 6 through the connecting tube 5. After the device completes the collection of the soil sample, the hand-held frame 1 is reversed and the turntable 10 is forwardly rotated, so that the lower end of the soil sample collection device leaves the soil, and the soil in the threaded sampling tube 2 is discharged through the bottom of the threaded sampling tube 2. At the same time, the compression elastic force of the spring 73 causes the corresponding closed door 71 to reverse and reset around the hinge, and the reverse reset stroke of the closed door 71 is limited by the tightening of the limit rod 74, so that the corresponding two closed doors 71 cooperate to block the corresponding connecting tube 5. When the next soil sample is collected, the locking limit of the locking bolt 75 of another collecting tube 6 is released by the same principle. The soil sample collection collector is equipped with multiple collecting tubes 6 at the upper end, which can be opened and closed separately according to the soil sample collection needs, without the need to frequently replace the collecting tubes 6.
[0025] The working principle of the soil sample collection device provided by the utility model is as follows: when collecting soil samples, the device is first moved to a designated position by the handheld frame 1, and then the lower side of the connecting seat 13 is brought into contact with the ground. Then, the staff member presses down the connecting seat 13 with both feet to make the ground-gripping spikes 14 penetrate into the soil, thereby fixing the device as a whole to the ground. Then, the handheld frame 1 is rotated forwardly by the handle 11, so that the threaded sampling tube 2 drives the hollow drill bit 3 to rotate forwardly. During the forward rotation of the threaded sampling tube 2, the lower end of the threaded sampling tube 2 is connected to the fixing seat 12 by a thread, so that the hollow drill bit 3 rotates to penetrate into the soil. The spiral torsion force is used inside the soil to make the soil sample collection part of the device penetrate into the soil, which is easy to operate and has low preparation cost. In this process, the spiral direction of the spiral upper material piece 9 is opposite to the direction of the thread groove of the threaded sampling tube 2, so as to avoid the spiral upper material piece 9 driving the soil to move up along the inner wall of the threaded sampling tube 2 when the threaded sampling tube 2 rotates forward and penetrates into the soil. When the lower end of the threaded sampling tube 2 penetrates into the corresponding soil collection part in the soil, the turntable 10 is then rotated in the reverse direction to drive the spiral upper material piece 9 to rotate through the rotating shaft 8. As the lower end of the threaded sampling tube 2 continues to penetrate into the soil, the spiral upper material piece 9 rotates to The soil sample at the bottom of the device moves vertically upward along the inner wall of the threaded sampling tube 2, and at the same time, the corresponding locking stud 75 is rotated to move it away from the locking groove, thereby releasing the flip limit of the closing door 71 corresponding to the collection tube 6 at this time. When the soil sample in the conversion shell 4 gathers to a certain extent, the contact pressure between the soil samples causes the unlocked closing door 71 to flip open around the corresponding hinge, and the fixed end of the arc-shaped telescopic column 72 and the spring 73 contract, thereby opening the corresponding connecting tube 5, and then the soil sample enters the corresponding collection tube 6 through the connecting tube 5, and the device completes the collection of the soil sample. Then, the hand-held frame 1 is rotated in the reverse direction and the turntable 10 is rotated forward respectively, so that the lower end of the soil sample collection device leaves the soil, and the soil in the threaded sampling tube 2 is discharged through the bottom of the threaded sampling tube 2. At the same time, the compression elastic force of the spring 73 causes the corresponding closing door 71 to reverse and reset around the hinge, and the reverse reset stroke of the closing door 71 is limited by the tightening of the limit rod 74, so that the corresponding two closing doors 71 cooperate to block the corresponding connecting pipe 5. When the next soil sample is collected, the locking limit of the locking bolt 75 of the other collecting tube 6 is released by the same principle.
