Description

Technical Field

[0001] The utility model relates to the technical field of soil surveying, in particular to a digging tool for a soil sampling pit. Background Art

[0002] During the soil testing process, the staff's working condition is that they need to dig a standard cubic piece of soil as the test target in a certain area. However, due to the different composition and quality of the soil, and the different temperatures and humidity of the soil, the internal density of the soil will also change with the external environment. The existing working method is: the staff mark the digging range and use a shovel to dig the soil. Since the shovel is a spatial curved surface, the digging angle and the digging trajectory cannot be standardized, resulting in inaccurate soil quality measurement data within the calibration range.

[0004] The specific technical solutions are as follows:

[0005] A assembled soil sampling pit excavation tool comprises four longitudinal rods, longitudinal slideways are arranged inside the longitudinal rods, cross rods are assembled in the longitudinal slideways, transverse slideways are arranged inside the cross rods, electric hammer assemblies are arranged inside the transverse slideways, and a level is arranged at the upper end of the longitudinal rods.

[0006] The electric hammer assembly includes a connecting block arranged in a transverse slideway, an electric hammer is fixedly connected to the lower part of the connecting block, an output end of the electric hammer is connected to a crushing vertical plate, the crushing vertical plate is a rectangular parallelepiped as a whole, and a slope is arranged at the lower end of the crushing vertical plate.

[0007] The longitudinal slideway of the longitudinal rod is arranged through the interior of the longitudinal rod, and the two longitudinal slideways of the longitudinal rod are arranged vertically connected to each other in the longitudinal rod; the lower vertebral body is arranged at the lower bottom end of the longitudinal slideway.

[0008] A lower vertebral body is arranged at the lower bottom end of the longitudinal slideway.

[0009] After the electric hammer assembly is assembled on the transverse slideway, the outer end surface of the crushing vertical plate of the electric hammer assembly is coplanarly arranged with the inner end surface of the longitudinal slideway of the longitudinal rod.

[0010] The width of the crushing vertical plate is greater than the width of the electric hammer of the electric hammer assembly.

[0011] The upper end of the connecting block of the electric hammer assembly is fixedly connected to a movable handle.

[0012] The advantages of the utility model are: the longitudinal rod and the cross rod are simple to assemble, easy to carry, and can be used in any place. At the same time, the assembly is simple and easy to assemble. At the same time, the crushing vertical plate is a rectangular parallelepiped, and during the working process, it can be directional along the longitudinal slide through the cooperation of the longitudinal rod. At the same time, the outer end face of the crushing vertical plate and the inner end face of the longitudinal slide are arranged coplanar. When defining the range, the inner end face of the longitudinal slide can be used as a positioning reference, and the problem of returning the ruler is not involved in the calibration process, which is convenient for the staff to define the range and reduce errors in the working process.

[0018] 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.

[0019] A digging tool for an assembled soil sampling pit is provided, wherein four longitudinal rods 1 are provided, longitudinal slideways 2 are provided inside the longitudinal rods 1, cross rods 3 are assembled in the longitudinal slideways 2, transverse slideways 4 are provided inside the cross rods 3, electric hammer assemblies 5 are provided inside the transverse slideways 4, the transverse slideways 4 are in an I-shape, and a level 11 is provided at the upper end of the longitudinal rods.

[0020] The electric hammer assembly 5 includes a connecting block 6 arranged in a transverse slideway, an electric hammer 7 is fixedly connected below the connecting block 6, and an output end of the electric hammer 7 is connected to a crushing vertical plate 8. The crushing vertical plate 8 is a rectangular parallelepiped as a whole, and a lower end portion 81 of the crushing vertical plate 8 is provided with an inclined surface.

[0021] The longitudinal slideway 2 of the longitudinal rod 1 is set through the interior 101 of the longitudinal rod, and the two longitudinal slideways 2 of the longitudinal rod 1 are connected to each other vertically in the longitudinal rod 101; the end 102 of the longitudinal rod 1 is set as an integral whole; the lower vertebral body is set at the lower bottom end of the longitudinal slideway.

[0022] A lower vertebral body 103 is disposed at the lower bottom end of the longitudinal slideway 2 .

[0023] After the electric hammer assembly 5 is assembled on the transverse slide 4, the outer end surface 81 of the crushing vertical plate 8 of the electric hammer assembly 5 is arranged coplanar with the inner end surface 104 of the longitudinal slide of the longitudinal rod.

[0024] The width of the crushing vertical plate 8 is greater than the width of the electric hammer 7 of the electric hammer assembly.

[0025] The upper end of the connecting block 6 of the electric hammer assembly 5 is fixedly connected to a movable handle 9 .

[0026] The electric hammer 7 involved in the present invention can be a commercially available product, such as the electric hammer product of model TE30 produced by Guangzhou Goodejia Construction Engineering Co., Ltd.

[0027] The working principle of the utility model is: first dig out a part of the soil within the designated range so that the excavated soil in subsequent work has a place to be stored, first take out four longitudinal rods and four cross rods, use hammers to hit the longitudinal rods to hammer the longitudinal rods into the soil, because the outer end face of the crushing vertical plate of the electric hammer assembly is coplanar with the inner end face of the longitudinal slide of the longitudinal rod, the inner wall of the longitudinal slide is the positioning reference, as long as the distance between the inner walls of the two longitudinal slides meets the designated size, the working position of the longitudinal rod can be determined, after hammering into the calibrated depth, the longitudinal rod should protrude a certain height from the upper surface of the soil, then take out four electric hammer assemblies, and respectively assemble the connecting blocks on the electric hammer assemblies into the cross slides of their respective cross rods (the figure only shows a schematic diagram of the position structure of the electric hammer assembly on one side. When four electric hammer assemblies are used, the four cross rods and the electric The connection method of the hammer assembly is consistent with the connection method of the electric hammer in the figure), and then the two ends of the cross bar are inserted into the longitudinal slide of the longitudinal bar. After assembly, the movable handle is connected to the connecting block, and the electric hammer is started. The staff holds the movable handle and moves horizontally in the cross bar while pressing down the electric hammer assembly, so that the cross bar assembly continues to work downward along the longitudinal slide of the longitudinal bar. The advantage of the utility model is that when the staff uses the electric hammer assembly to move horizontally, since the width of the crushing vertical plate is greater than the width of the electric hammer of the electric hammer assembly, the crushing vertical plate can be moved to the longitudinal bar and can be extended into the inner wall of the longitudinal bar, so that a complete quadrilateral can be cut out. During the working process, the cross bar is continuously moved to make the cross bar work along the track in the longitudinal slide, so that the cubic soil required for the work can be obtained.
