Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of highway engineering soil taking, and specifically relates to a soil sampling device for highway engineering. BACKGROUND

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, management and other work of highway structures, including roadbed, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. The highway construction of a country should consider its role and position in intermodal transportation in combination with railway, waterway and aviation transportation, and formulate a national highway network planning according to grades in combination with geographical environmental conditions according to political, military, economic and people's life needs. In the early stage of highway construction, the soil is sampled and detected to avoid excessive acid and alkali substances in the soil, which may cause the collapse of the highway in the later stage. Therefore, a soil sampling device is needed.

[0003] According to the search, the patent with the Chinese patent application number 202122910503.0 discloses a soil sampling device for highway engineering, which is composed of a cleaning mechanism and a rotating mechanism. By means of the working principle of the lead screw and the transmission principle of the worm and the worm wheel, the two first brushes can be retracted. By setting the second brush and the first brush, the inside wall of the sampling cylinder can be cleaned longitudinally and transversely when the sampling pipe pushes out the sampled soil in the sampling cylinder. By setting the first stepping motor and the sampling column, the sampling pipe and the cleaning mechanism inside the sampling pipe can be rotated at high speed, so as to clean the inside wall of the sampling cylinder without dead angle, and further improve the cleaning effect.

[0004] The above patent has the following disadvantages: 1. When sampling soil, if the soil hardness is high, it is difficult to concentrate the soil in the inside of the sampling plate, which reduces the practicability; 2. Because the structure inside the sampling cylinder is complex, it is difficult to maintain continuous operation of the internal structure during long-term use. When the internal structure is damaged, the maintenance is complex, which is not convenient for long-term use of the sampling cylinder.

[0005] Therefore, a soil sampling device for highway engineering is needed to solve the above problems. UTILITY MODEL CONTENTS

[0006] The purpose of this utility model is to address the following problems: when soil hardness is high during soil sampling, the sampling plate is not easy to concentrate the soil inside, resulting in low practicality; due to the complex internal structure of the sampling tube, it is difficult to maintain continuous operation during long-term use, and the repair is complicated when the internal structure is damaged, thus making it inconvenient for the long-term use of the sampling tube.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A soil sampling device for highway engineering is proposed to improve the above-mentioned problems.

[0027] As Figures 1-2 As preferred embodiments, on the basis of the above-mentioned mode, further, the reciprocating assembly includes a fixed rod 110 fixedly connected to the outer wall of the handheld rod 100, a first spring 111 sleeved to the outer wall of the fixed rod 110, and a pressing block 112 slidably connected to the outer wall of the fixed rod 110. The end of the pressing block away from the fixed rod 110 is fixedly connected to the screw ring 106. A pressure plate 113 is fixedly connected to the side wall of the screw ring 106. The two ends of the first spring 111 are fixedly connected to the fixed rod 110 and the pressing block 112, respectively. By providing the pressure plate 113, the pressing can be more convenient, and the use is more convenient.

[0028] As Figures 1-3 As preferred embodiments, on the basis of the above-mentioned mode, further, the soil taking part includes a soil taking ring 120 screwedly connected to the outer wall of the soil drilling axle 104. A soil taking groove 121 is formed in the inner wall of the soil taking ring 120. A knocking ring 122 is rotationally connected to the outer wall of the soil taking ring 120. By rotating the knocking ring 122, the soil can be more conveniently taken out from the inside of the soil taking ring 120, and the utility is stronger.

[0029] As Figures 1-5As shown, in a preferred embodiment, based on the above method, further, a uniformly distributed guide rod 123 is fixedly connected to the inner wall of the striking ring 122, a rotating frame 124 is fixedly connected to the outer wall of the soil-collecting ring 120, a striking rod 125 is rotatably connected to the side wall of the rotating frame 124, a deflection block 126 is rotatably connected to the outer wall of the striking rod 125, a second spring 127 is fixedly connected to the side wall of the deflection block 126, and the end of the second spring 127 away from the deflection block 126 is also fixedly connected to the soil-collecting ring 120.

Then, hold the handle 100 with one hand and press down on the pressure plate 113 with the other. The pressure plate 113 causes the threaded ring 106 to slide downwards. Under the action of the threaded ring 106 and the threaded groove 105, the drill rod 103 rotates. When the drill rod 103 rotates, the drilling shaft 104 rotates synchronously. When the pressure plate 113 is pressed to its limit position, release the pressure plate 113. Under the action of the first spring 111, the pressing block 112 resets. When the pressing block 112 resets, the drilling shaft 104 also rotates synchronously. The above steps are repeated to achieve the desired effect. The soil is loosened by repeating the operation. Then, the soil-collecting ring 120 is rotated downwards. When the soil-collecting ring 120 is rotated to the appropriate position, the hand lever 100 is pressed downwards to collect soil through the soil-collecting groove 121. After the soil collection is completed, the striking ring 122 is rotated according to the direction indicated by the pointer 128. When the striking ring 122 rotates, it drives the guide rod 123 to squeeze the striking rod 125, thereby causing the striking rod 125 to deflect. When the guide rod 123 moves away from the striking rod 125, the striking rod 125 is reset under the action of the second spring 127, thus realizing the striking of the soil-collecting ring 120, making it easier to remove the soil from the soil-collecting groove 121 and improving the convenience of use.
