Description

Technical Field

[0001] The invention relates to the technical field of soil collection equipment, and in particular to a forestry soil collection and investigation device. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is an important part of the national economy. In the work of forestry survey, collecting and testing the soil in the forest is one of the necessary investigation tasks.

[0003] In the existing soil collection work for forestry, soil samples are still obtained by driving a drill into the soil. Compared with the flat terrain on the ground, the soil in the forest is soft and uneven. It is difficult to align the drill with the collection point when using a traditional drill to take soil samples in the forest. In addition, the soft soil will lack certain stability during the collection process. In addition, due to its heavy volume and output power, traditional soil sampling equipment usually chooses gasoline or diesel in terms of energy. Using these petroleum energy sources in the forest is also prone to cause fires, which poses certain safety hazards to the forest and workers.

[0004] In order to solve the above problems, a soil collection device is proposed which avoids the use of petroleum energy and can stably sample soil in the forest. Summary of the invention

[0020] refer to Figures 1 to 9 , a forestry soil collection and investigation device, comprising an outer barrel 1, a U-shaped bracket 2, an L-shaped mounting plate 3, a horizontal mounting plate 4, a roller 12, a wheel rod 11, a ground insertion rod 15, a collection barrel 18, a movable barrel 24, a sliding mechanism, a rotating mechanism, a driving mechanism, a labor-saving lever mechanism, and a fixing mechanism; The same U-shaped bracket 2 is fixedly mounted on the front and rear side walls of the outer barrel 1. The outer barrel 1 is fixedly mounted between the two vertical rod ends of the U-shaped bracket 2. The outer barrel 1 is used to wrap the collection barrel 18 described later and provide a fixed sliding direction for it to slide up and down. The U-shaped bracket 2 is used to connect the outer barrel 1 and itself into a whole, and can be used to fix the outer barrel 1 so that the bottom end of the outer barrel 1 can be located above the soil; The upper end of the crossbar of the U-shaped bracket 2 is fixedly mounted with a vertical plate of an L-shaped mounting plate 3, and the horizontal plate of the L-shaped mounting plate 3 is mounted above the U-shaped bracket 2. The L-shaped mounting plate 3 is used to mount the horizontal mounting plate 4 described later, and also provides a mounting platform for the rotating mechanism described later; A horizontal mounting plate 4 is vertically mounted on the front wall of the vertical plate of the L-shaped mounting plate 3. The horizontal mounting plate 4 is mounted between the horizontal plate of the L-shaped mounting plate 3 and the horizontal plate of the U-shaped bracket 2. The horizontal mounting plate 4 is used to mount the driving mechanism described later. A driving mechanism is installed on the upper end of the horizontal mounting plate 4, and the main body of the driving mechanism is a driving motor described later, which avoids the use of traditional fossil energy; A movable barrel 24 is slidably installed in the outer barrel 1, and the movable barrel 24 is driven to slide by a labor-saving lever mechanism. The labor-saving lever mechanism can drive the movable barrel 24 more labor-savingly through the lever principle, making up for the disadvantage that the output power of the driving motor is less than that of the traditional hydraulic motor; The lower end of the movable barrel 24 is rotatably mounted with a collecting barrel 18, and the collecting barrel 18 is movably mounted in the outer barrel 1; The collecting barrel 18 is driven to rotate by the rotating mechanism, and the rotating mechanism is driven to work by the driving mechanism; A transmission mechanism is installed at the lower end of the horizontal mounting plate 4, and the labor-saving lever mechanism is driven by the transmission mechanism to work, so that the collection bucket 18 can move up and down with the movable bucket 24, and can also rotate under the drive of the rotating mechanism while moving up and down, so that the collection bucket 18 will not encounter too much resistance when rotating into the soil; The transmission mechanism is driven by the driving mechanism to work; Two wheel rods 11 are movably mounted on the outer sides of the two vertical rods of the U-shaped bracket 1, and rollers 12 are rotatably mounted on the lower ends of the four wheel rods 11; The upper ends of the two wheel rods 11 on the same side are fixedly arranged between them; The two wheel rods 11 on the same side are arranged at an obtuse angle, and the two wheel rods 11 on both sides are arranged at an obtuse angle to increase the overall stability of the device. In addition to assisting the device in moving, the rollers 12 can also reduce friction by rolling when the collection bucket 18 is inserted into the soil. The two wheel rods 11 on the same side are driven to slide by the effort-saving lever mechanism; The outer sides of the two wheel rods 11 on the same side are movably mounted with the same ground-inserting rod 15, and the two ground-inserting rods 15 are driven to move by the fixing mechanism. The ground-inserting rods 15 on both sides can be sunk into the soil under the drive of the fixing mechanism, thereby increasing the fastening ability between the equipment and the ground. The two wheel rods 11 on the same side respectively drive the fixing mechanism close thereto to work by sliding. During the sliding process of the wheel rods 11 on both sides, the ground-inserting rods 15 on both sides can slide downward at an angle, thereby reducing the resistance of inserting into the soil and better fixing the equipment.

[0021] The labor-saving lever mechanism comprises a first rectangular slider 2401, a first connecting rod 13, a second connecting rod 14, a second rectangular slider 23, and a third rectangular slider 20; A first rectangular sliding block 2401 is fixedly mounted on the front wall of the movable barrel 24, and a first rectangular through groove 101 cooperating with the first rectangular sliding block 2401 is provided on the front wall of the outer barrel 1; The first rectangular sliding block 2401 is slidably arranged to penetrate the first rectangular through slot 101; First connecting shafts are fixedly mounted on the upper ends of the left and right side walls of the outer barrel 1, and first ends of the first connecting rods 13 are rotatably mounted on the two first connecting shafts. The inner walls of the two first connecting rods 13 are respectively provided with first rectangular sliding grooves 1301, and the second rectangular sliding blocks 23 are respectively slidably installed in the two first rectangular sliding grooves 1301, and the same second connecting shaft is fixedly installed between the inner walls of the two second rectangular sliding blocks 23; The second connecting shaft is rotatably connected to the first rectangular sliding block 2401; The first ends of the second connecting rods 14 are rotatably mounted on the inner walls of the second ends of the two first connecting rods 13 respectively; The two vertical plates of the U-shaped bracket 2 are respectively provided with second rectangular through slots 201; The third rectangular sliders 20 are slidably mounted in the two second rectangular through grooves 201, respectively, and the inner walls of the two third rectangular sliders 20 are fixedly connected via a transmission shaft 26; The two ends of the transmission shaft 26 are respectively slidably arranged between the second rectangular through slots 201 adjacent thereto; The outer walls of the two third rectangular sliding blocks 20 are respectively fixedly mounted with third connecting shafts; The second ends of the two second connecting rods 14 are respectively rotatably sleeved on the outer wall of the third connecting shaft close thereto; The two third connecting shafts respectively drive the two ground insertion mechanisms to work by sliding; The two third rectangular sliders 20 are driven to slide by the transmission mechanism. The two third rectangular sliders 20 start to slide back and forth along the second rectangular through slots 201 on both sides under the drive of the transmission mechanism, and drive the second connecting rods 14 on both sides to start to deflect during the sliding process. Figure 2When the third rectangular sliders 20 on both sides slide to the right, they will drive the second connecting rods 14 on both sides to start to deflect downward, and pull the first connecting rods 13 on both sides to start to rotate downward during the downward deflection. The first connecting rods 13 on both sides drive the second rectangular sliders 23 on both sides to slide downward along the first rectangular slide grooves 1301 on both sides during the downward rotation. Since the rotation centers of the first connecting rods 13 on both sides have been determined, the lower ends of the two first connecting rods 13 are pulled by the two second connecting rods 14 to start to slide downward. At this time, the first connecting rods 13 on both sides start to rotate downward around their own rotation centers, and are subjected to force during the rotation process. The point is at the end farthest from its rotation center. According to the principle of lever, the length of the entire first connecting rod 13 can be approximately regarded as the entire force arm, which realizes the effort-saving effect. The second rectangular sliders 23 on both sides are driven by the first connecting rod 13 to slide downward along the first rectangular slide grooves 1301 on both sides, and drive the first rectangular slider 2401 coaxially fixed therewith to slide downward along the first rectangular through groove 101. The movable barrel 24 fixedly installed with the first rectangular slider 2401 can now slide downward under the drive of the first connecting rod 13 after the force is amplified, and drive the collecting barrel 18 rotatably mounted therewith to start sliding downward, providing longitudinal pressure for the collecting barrel 18 to be inserted into the soil.

[0022] The transmission mechanism comprises a rectangular rod 21, a fourth rectangular slider 22, and a disc 16; A disc 16 is rotatably mounted on the lower end of the horizontal mounting plate 4 via a first rotating shaft, and a fourth connecting shaft is fixedly mounted at an eccentric position on the lower end of the disc 16; A fourth rectangular slider 22 is rotatably mounted on the fourth connecting shaft; The upper ends of the two third rectangular sliding blocks 20 are respectively fixedly mounted with expansion blocks 2001; The upper ends of the two vertical rods of the U-shaped bracket 2 are respectively provided with third rectangular through slots 2011 that cooperate with the expansion block 2001, and the two third rectangular through slots 2011 are respectively connected to the second rectangular through slots 201 that cooperate with them; The two expansion blocks 2001 are respectively slidably arranged to penetrate the third rectangular through slots 2011 adjacent thereto; The upper ends of the two expansion blocks 2001 are fixedly mounted with a same rectangular rod 21, and the rectangular rod 21 is movably mounted between the two vertical rods of the U-shaped bracket 2 and the disc 16; A second rectangular slide groove 2101 is provided at the upper end of the rectangular rod 21, and the fourth rectangular slider 22 is slidably installed in the second rectangular slide groove 2101; The first rotating shaft is driven by the driving mechanism, refer to Figure 3, the first rotating shaft starts to rotate under the drive of the driving mechanism, and during the rotation process, it drives the disc 16 fixedly mounted coaxially therewith to start rotating. During the rotation process, the disc 16 drives the fourth connecting shaft at the eccentric position of its lower end to start rotating around the rotation center of the disc 16. The fourth rectangular slider 22 rotatably sleeved on the fourth connecting shaft now has the ability to synchronously rotate around the rotation center of the disc 16, and the fourth rectangular slider 22 also reciprocates along the second rectangular slide groove 2101 during the rotation process. Therefore, the fourth rectangular slider 22 converts the rotation driving force into the reciprocating sliding ability of the rectangular rod 21 through the second rectangular slide groove 2101. Since the sliding trajectories of the two expansion blocks 2001 fixedly connected to the rectangular rod 21 are limited in the third rectangular through groove 2011 matched therewith, the trajectory of the rectangular rod 21 is determined during the sliding process, and it is ensured that it will not deviate during the sliding process. At this time, the two third rectangular sliders 20 fixedly mounted on the two expansion blocks 2001 can start to reciprocate along the second rectangular through groove 201 matched therewith under the drive of the two expansion blocks 2001.

[0023] The driving mechanism comprises a driving motor, a first spur gear 5, and a second spur gear 6; The upper end of the first rotating shaft rotates through the horizontal mounting plate 4 to fix a second spur gear 6, and a driving motor is installed on one side of the second spur gear 6; The driving motor is fixedly mounted on the upper end of the horizontal mounting plate 4, and a first spur gear 5 is mounted on a fixed sleeve on the output shaft of the driving motor, and the first spur gear 5 is meshed with a second spur gear 6; The second spur gear 6 drives the rotating mechanism to work by rotating, and the driving motor is started. The output shaft of the driving motor starts to rotate and drives the first spur gear 5 coaxially fixed therewith to start rotating. During the rotation process, the first spur gear 5 can drive the second spur gear 6 meshing therewith to start rotating. During the rotation process, the second spur gear 6 can drive the disc 16 coaxially fixed therewith to start rotating.

[0024] The rotating mechanism comprises a second rotating shaft 9, a first sprocket 7, a second sprocket 8, a hollow rotating shaft 10, a rectangular guide rod 25, and a fixed shaft 1801; A first end of a second rotating shaft 9 is fixedly mounted at the center of the upper end of the second spur gear 6; The second end of the second rotating shaft 9 rotates through the horizontal plate of the L-shaped mounting plate 3 and is fixedly mounted with the first sprocket 7; The first end of a fixed shaft 1801 is fixedly mounted on the upper end of the collecting barrel 18, and the fixed shaft 1801 is rotatably intersected with the top wall of the movable barrel 24; A rectangular guide rod 25 is fixedly mounted on the second end of the fixed shaft 1801, and the rectangular guide rod 25 is mounted above the movable barrel 24; A hollow rotating shaft 10 is installed through the top wall of the outer barrel 1, and the hollow rotating shaft 10 is rotatably arranged between the top wall of the outer barrel 1; The lower end of the hollow shaft 10 is provided with a rectangular through hole 1001 which cooperates with the rectangular guide rod 25; The rectangular guide rod 25 is slidably installed in the rectangular through hole 1001; A second sprocket 8 is fixedly mounted on the outer wall of the hollow rotating shaft 10, and the second sprocket 8 is rotatably mounted on the upper end of the top wall of the outer barrel 1; The first sprocket 7 and the second sprocket 8 are sleeved with a same chain on their outer walls. Figure 2 When the second spur gear 6 drives the first sprocket 7 coaxially fixed therewith to start rotating during the rotation process, the first sprocket 7 transmits the rotation driving force to the second sprocket 8 through the chain to make the second sprocket 8 start rotating. During the rotation process, the second sprocket 8 drives the hollow rotating shaft 10 fixed therewith to start rotating. The hollow rotating shaft 10 is rotatably connected to the top wall of the outer barrel 1 through the card groove and the arc-shaped card block, so it will not fall off during the rotation process. During the rotation process, the hollow rotating shaft 10 will also drive the rectangular guide rod 25 slidably installed therein to start rotating. During the rotation process, the rectangular guide rod 25 can drive the fixed shaft 1801 fixed therewith to start rotating. The fixed shaft 1801 can drive the collecting barrel 18 fixed therewith to start rotating by rotating. The collecting barrel 18 can slide up and down with the drive of the movable movable barrel 24 and can also be driven to rotate by the rectangular guide rod 25, so that the collecting barrel 18 can rotate while probing downward into the soil, greatly increasing the collection efficiency.

[0025] The fixing mechanism comprises a third connecting rod 17 and a rectangular block 19; The upper ends of the two wheel rods 11 on the same side are fixedly connected by a connecting plate, and the two connecting plates are respectively fixedly connected to the outer wall of the third connecting shaft close thereto. The outer ends of the two third connecting shafts are respectively penetrated through the connecting plates close thereto and are fixedly mounted with rectangular blocks 19, and the two rectangular blocks 19 are respectively mounted on the outer sides of the wheel rods 11 close thereto; The two rectangular blocks 19 are respectively provided with fourth rectangular through slots, and the two ground-inserting rods 15 are respectively slidably arranged between the fourth rectangular through slots adjacent thereto; The upper outer walls of the two ground-inserting rods 15 are respectively fixedly mounted with fifth connecting shafts, and the two fifth connecting shafts are respectively movably mounted above the rectangular blocks 19 close thereto; The first ends of the third connecting rods 17 are rotatably mounted on the outer walls of the two fifth connecting shafts respectively; The left and right side walls of the horizontal plate of the L-shaped mounting plate 3 are respectively fixedly mounted with a sixth connecting shaft; The second ends of the two third connecting rods 17 are respectively mounted on the outer wall of the sixth connecting shaft close thereto. Figure 2 When the third rotating shafts on both sides begin to slide toward the right, the rectangular blocks 19 on both sides also begin to slide toward the right synchronously. In the process of the rectangular blocks 19 on both sides sliding toward the right, the third connecting rods 19 on both sides begin to deflect downward, and drive the ground-inserting rods 15 on both sides to slide downward in the process of downward deflection. In the process of sliding downward, the ground-inserting rods 15 on both sides are also synchronously driven by the rectangular blocks 19 on both sides to slide toward the right. Therefore, the moving direction of the ground-inserting rods 15 on both sides is oblique downward movement. After contacting the soil, they can sink into the soil at a certain angle, avoiding vertical insertion into the soil with greater resistance, so that the ground-inserting rods 15 on both sides can lift the equipment.

[0026] A sealable opening and closing door is installed on the side wall of the collecting barrel 18, and a notch for exposing the opening and closing door is provided on the rear wall of the outer barrel 1. When the collecting barrel 18 is lifted upward, the collecting barrel 18 is full of soil. The soil inside can be dumped out by simply opening the opening and closing door. The opening and closing method of the opening and closing door is a snap-on opening and closing method, which is the prior art and will not be elaborated here.

[0027] Implementation method of the present invention: Push the device into the forest, align the collection bucket 18 in the device with the point to be collected, start the drive motor, and when the drive motor starts working, the collection bucket 18 starts to rotate and gradually presses downward during the rotation process; The downward pressing of the collecting barrel 18 is achieved by the downward deflection of the first connecting rods 13 on both sides. The first connecting rod 13 can drive the collecting barrel 18 downward with a smaller output force under the drive of the force-saving lever mechanism. Since the soil in the forest is relatively soft, it is possible to avoid using high-power fossil energy equipment; In the process of pressing the collecting bucket 18 downward, refer to Figure 2 , the ground-inserting rods 15 on both sides of the equipment slide downward synchronously and slide toward the right side during the downward sliding process. The four rollers 12 reduce the friction force of the ground-inserting rods 15 sliding to the right side at this time, and also reduce the resistance generated when the first connecting rods 13 on both sides deflect downward. After the ground-inserting rods 15 on both sides are completely sunk into the soil, since their sliding trajectories are not perpendicular to the soil, part of the soil will be piled up from under the ground. At this time, the staff needs to refill the soil; As the collecting barrel 18 slides upward, the collecting barrel 18 can be fully loaded with soil and leave the ground with the fully loaded soil. At the same time, the ground-inserting rods 15 on both sides are also re-activated above the soil, the driving motor is turned off, and the equipment is pushed to the detection point. The staff opens the opening and closing door installed on the collecting barrel 18 and pours out the soil inside.

[0028] The present invention avoids the use of traditional petroleum energy during use, reduces the probability of fire in the forest, and can smoothly insert the collection bucket into the soil through the labor-saving lever mechanism, and smoothly realize the collection of soil by the sliding bucket under the drive of the sliding mechanism. The fixing mechanism of the present invention can be inserted into the lower layer of the soil at the same time during use, which increases the stability of the equipment during operation.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
