[0015] The present invention provides a soil sample collector for water conservancy project construction, which has the following beneficial effects: (1) The present invention comprises a rectangular shell, a servo motor 1, a screw rod, a straight ring block, a driving module, a circular cover, a screw tube, a transverse hole plate, a thin rod, a spring 1, a circular plate, a round rod and a roller with a convex block. The circular plate leaves the soil inlet of the screw tube and the soil enters the screw tube. When the screw tube collects soil, the rotating shafts of the servo motor 1 and the servo motor 2 rotate and reset. At this time, the extrusion force on the circular plate is reduced. Under the elastic force of the spring 1, the thin rod slides downward in the transverse hole plate, and the thin rod drives the circular plate to move downward, so that the circular plate blocks the soil inlet of the screw tube, thereby preventing the sampled soil from falling into the screw tube and causing the equipment to collect soil poorly.

In addition, the U-shaped block moves downward in the sliding gap of the rectangular shell, and under the action of the friction force, the vibration amplitude of the screw tube during rotation is reduced, thereby preventing the screw tube from rotating and digging and generating a strong amplitude, resulting in poor screw tube rotation and digging effect.

[0017] (3) The present invention arranges the maintenance device so that the bent rod, the arc plate, the spring three, the square plate, the sponge block, the double ring frame and the short rod cooperate with the chamfered plate. Under the elastic force of the spring three, the sponge block is pressed against the screw rod and moves downward. The sponge block applies lubricating oil to the surface of the screw rod to prevent the surface of the screw rod from aging and rusting, which causes the equipment to run unsmoothly. The short rod drives the chamfered plate to move downward. During the downward movement of the chamfered plate, the chamfered plate scrapes the slide groove of the rectangular shell clean to prevent foreign matter from accumulating in the slide groove of the rectangular shell, which causes the straight ring block to slide unsmoothly.

The outer wall of the straight block 114 is slidably connected with the inner wall of the slide groove of the rectangular shell 111. A driving module 115 is fixedly installed on the left side of the ring straight block 114. The driving module 115 includes a round shell and a servo motor 2. The round shell is fixed to the left side of the ring straight block 114. The servo motor 2 is fixedly installed on the top of the inner side of the round shell. A circular cover 116 is fixed to the bottom surface of the servo motor 2 shaft of the driving module 115. A screw tube 117 is fixedly installed on the outer wall of the circular cover 116. The bottom surface of the screw tube 117 is provided with a soil inlet. A transverse hole plate 171 is fixed to the bottom of the inner wall of the screw tube 117.

A thin rod 172 is slidably installed through the middle, a round block is provided at the bottom of the outer wall of the thin rod 172, one end of the spring 173 away from the transverse hole plate 171 is fixedly connected to the top surface of the round block of the thin rod 172, a round plate 174 is fixed to the bottom surface of the thin rod 172, the rectangular shell 111 is located on the left side of the U-shaped handle 2, and the rectangular shell 111 is provided with sliding seams on both sides, and the top of the outer wall of the screw tube 117 is provided with two L-shaped notches, and the two L-shaped notches of the screw tube 117 are clamped on the outer wall of the circular cover 116, the screw tube 117 is located above the round mouth of the cart 1, the round plate 174 is located above the soil inlet of the screw tube 117, and the round plate 174 leaves the screw tube 11 7, soil enters the screw tube 117, and the screw tube 117 rotates to enter the soil collection point to collect soil. When the screw tube 117 collects soil, the rotating shafts of the servo motor 112 and the servo motor 2 rotate and reset. At this time, the extrusion force on the circular plate 174 is reduced. Under the elastic force of the spring 173, the thin rod 172 slides downward in the transverse hole plate 171, and the thin rod 172 drives the circular plate 174 to move downward, so that the circular plate 174 blocks the soil inlet of the screw tube 117, so as to prevent the sampled soil from falling into the screw tube 117 when the soil sample collector extracts the soil sample, resulting in poor soil collection effect of the equipment; A positioning assembly 12 is provided on the front of the straight ring block 114, and the positioning assembly 12 includes a round rod 121, which passes through and is fixed on the front of the straight ring block 114, and is located on the left side of the rectangular shell 111. Two rollers 122 are rotatably installed on the outer wall of the round rod 121, and the two rollers 122 are located in front and rear of the straight ring block 114. A number of protrusions 123 are respectively fixed on the outer walls of the two rollers 122, and the two rows of recessed inner walls of the rectangular shell 111 are on the movement trajectory of the outer walls of the protrusions 123. When the protrusions 123 roll downward, the protrusions 123 are stuck in the recesses of the rectangular shell 111, so that the operator can accurately control the depth of the screw tube 117 when it rotates downward, so as to avoid the soil sampled by the soil sample collector being unqualified due to inaccurate depth of the screw tube 117 when collecting soil.

[0022] When in use, the operator pushes the cart 1 to the construction site of the water conservancy project through the U-shaped handle 2. Since the soil is easy to fall into the spiral tube 117 during the soil sampling process, when sampling is performed, the cart 1 reaches the designated sampling position, and the cart 1 supports the rectangular shell 111. The operator starts the servo motor 112 in the rectangular shell 111, and the rotating shaft of the servo motor 112 starts to rotate forward. The rotating shaft of the servo motor 112 drives the screw 113 to rotate forward, and the screw 113 rotates forward in the rectangular shell 111. Under the restriction of the slide groove of the rectangular shell 111, the straight ring block 114 is in the spiral groove of the screw 113. The straight ring block 114 moves downward in the slide groove of the rectangular shell 111, and the straight ring block 114 drives the driving module 115 to move downward. The operator starts the servo motor 2 in the driving module 115, and the shaft of the servo motor 2 starts to rotate forward. The shaft of the servo motor 2 drives the circular cover 116 to rotate forward, and the circular cover 116 drives the screw tube 117 to rotate forward. At the same time, the driving module 115 drives the circular cover 116 to move downward, and the circular cover 116 drives the screw tube 117 to move downward. In the process of the screw tube 117 moving downward, the screw tube 117 enters the round mouth of the cart 1, and the screw tube 117 The screw tube 117 is in contact with the ground. Under the action of the rotation force of the screw tube 117, the screw tube 117 is rotated and inserted into the soil of the water conservancy project construction site. Under the action of the extrusion force, the soil moves upward against the circular plate 174, and the circular plate 174 moves upward against the thin rod 172. The thin rod 172 slides upward in the cross-hole plate 171, and the spring 173 on the thin rod 172 begins to shrink. The circular plate 174 leaves the soil inlet of the screw tube 117, and the soil enters the screw tube 117. The screw tube 117 rotates to enter the soil collection point to collect the soil. When the screw tube 117 collects the soil, the rotating shaft of the servo motor 112 begins to reverse. The circular plate 174 is moved downwards to block the soil inlet of the spiral tube 117, thereby preventing the sampled soil from falling into the spiral tube 117 when the equipment is in use, thereby avoiding the problem that the sampled soil falls into the spiral tube 117 when the soil sample collector is extracting soil samples, resulting in poor soil collection effect of the equipment.

[0023] When the straight ring block 114 moves downward in the slide groove of the rectangular shell 111, the straight ring block 114 drives the round rod 121 to move downward, and the round rod 121 drives the roller 122 to move downward. Under the action of friction, the roller 122 rolls downward on the rectangular shell 111. At the same time, the roller 122 drives the protrusion 123 to roll downward. During the rolling process of the protrusion 123, the protrusion 123 is stuck in the recess of the rectangular shell 111, so that the operator can accurately control the depth of the screw tube 117 when it rotates downward, thereby preventing the depth of the screw tube 117 from being inaccurately controlled when the equipment is in use, thereby avoiding the sampled soil being unqualified due to the inaccurate depth of the screw tube 117 when the soil sample collector is collecting soil.

When the rubber block 34 moves downward, the rubber block 34 contacts the cart 1. Under the action of the extrusion force, the rubber block 34 slides upward in the square shell 32, and the spring 2 33 on the rubber block 34 begins to shrink. Under the elastic force of the spring 2 33, the straight ring block 114 will not collide with the slide groove of the rectangular shell 111 during the downward movement, thereby preventing the straight ring block 114 from colliding with the slide groove of the rectangular shell 111 when the soil sample collector is collecting soil, causing damage to the internal parts of the equipment.

[0025] The limiting device 3 also includes two annular arc plates 35, two cross bars 36 and two U-shaped blocks 37.

Lubricating oil is provided inside the two sponge blocks 45. Under the elastic force of the spring three 43, the sponge blocks 45 are pressed against the screw 113 and move downward. The sponge blocks 45 apply the lubricating oil to the surface of the screw 113 to prevent the surface of the screw 113 from aging and rusting when the soil sample collector is used for a long time, causing the equipment to run unsmoothly.

In the process of the chamfered plates 48 moving downward, the chamfered plates 48 scrape the chute of the rectangular shell 111 clean to avoid the accumulation of foreign matter in the chute of the rectangular shell 111 when the soil sample collector is collecting soil, causing the straight ring block 114 to slide unsmoothly.

[0029] When the straight ring block 114 drives the round rod 121 to move downward, the round rod 121 drives the U-shaped ring rod 31 to move downward, the U-shaped ring rod 31 drives the square shell 32 to move downward, the square shell 32 drives the spring 2 33 to move downward, the spring 2 33 drives the rubber block 34 to move downward, and in the process of the rubber block 34 moving downward, the rubber block 34 contacts the cart 1, and under the action of the extrusion force, the rubber block 34 slides upward in the square shell 32, and the spring 2 33 on the rubber block 34 begins to shrink. Under the elastic force of the spring 2 33, the straight ring block 114 will not collide with the slide groove of the rectangular shell 111 during the downward movement, so as to prevent the straight ring block 114 from hitting the slide groove of the rectangular shell 111 when the equipment is in use, thereby avoiding the problem that the straight ring block 114 hits the slide groove of the rectangular shell 111 when the soil sample collector is collecting soil, causing damage to the internal parts of the equipment.

[0030] While the round rod 121 drives the U-shaped ring rod 31 to move downward, the U-shaped ring rod 31 drives the arc plate 35 to move downward, the arc plate 35 drives the cross bar 36 to move downward, and the cross bar 36 drives the U-shaped block 37 to move downward. The U-shaped block 37 moves downward in the sliding gap of the rectangular shell 111. Under the action of friction, the vibration amplitude of the screw tube 117 during rotation is reduced, preventing the screw tube 117 from rotating and digging the soil to generate a strong amplitude when the equipment is in use, thereby avoiding the problem of poor digging effect of the screw tube 117 due to the strong amplitude generated by the screw tube 117 rotating and digging the soil when the soil sample collector is collecting soil.

[0031] While the cross bar 36 drives the U-shaped block 37 to move downward, the U-shaped block 37 drives the bent rod 41 to move downward, the bent rod 41 drives the arc plate 42 to move downward, the arc plate 42 drives the spring three 43 to move downward, the spring three 43 drives the square plate 44 to move downward, the square plate 44 drives the sponge block 45 to move downward, and under the elastic force of the spring three 43, the sponge block 45 is pressed against the screw 113 and moves downward, and the sponge block 45 applies lubricating oil to the surface of the screw 113 to prevent the surface of the screw 113 from aging and rusting during the long-term use of the equipment, thereby avoiding the problem of the equipment running smoothly due to the aging and rusting of the surface of the screw 113 during the long-term use of the soil sample collector.

[0032] While the U-shaped block 37 drives the bent rod 41 to move downward, the bent rod 41 drives the double ring frame 46 to move downward, the double ring frame 46 drives the short rod 47 to move downward, and the short rod 47 drives the chamfered plate 48 to move downward. During the downward movement of the chamfered plate 48, the chamfered plate 48 scrapes the slide groove of the rectangular shell 111 clean to prevent foreign matter from accumulating in the slide groove of the rectangular shell 111 when the equipment is in use, thereby avoiding the problem of foreign matter accumulating in the slide groove of the rectangular shell 111 when the soil sample collector is collecting soil, causing the straight ring block 114 to slide unsmoothly.
