This requires the use of a brush to clean the test surface after the final test. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing road material strength testing instruments inevitably damage the test materials during use, resulting in dust, small pieces and large pieces of material. After testing the next piece of test material, the test surface needs to be cleaned to ensure that the test material is placed horizontally and to ensure testing accuracy. This requires the use of a brush to clean the test surface after the final test. The invention provides a road strength testing instrument device for road surfaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a road strength tester device for road surface testing, comprising a road strength tester body; a pair of conical tubes symmetrically sleeved on the road strength tester body; a plurality of cross grooves opened in the conical tubes; a movable support plate rotatably connected in the cross grooves; a through groove opened in the movable support plate; an elastic membrane fixedly connected in the through groove; and a folded membrane fixedly connected to the inner side of the movable support plate.

[0008] Furthermore, the two semi-conical tubes together form a frustum shape.

[0009] Furthermore, the folded membrane is made of a non-elastic material; the elastic membrane is made of an elastic material.

[0010] The road strength meter device for road surface testing provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses an elastic membrane and a folded membrane to form an enclosing ring to receive falling particles. By changing the unfolding angle of the movable support plate, the unfolding area of ​​the receiving enclosing ring can be increased, which can hold more particles generated during detection and can detect particles generated after a long period of time and transfer them at once, thereby improving the efficiency of continuous detection of roadbed materials.

[0012] 2. This utility model uses an elastic membrane to keep the movable support plate in a stored state. The folded membrane can also deform and remain in a stored state. When it is necessary to unfold the movable support plate to receive and detect small stones and particles, a counterweight is applied to the movable support plate to unfold it, increasing the receiving area, thereby allowing the particles generated during detection to be collected in a concentrated manner.

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0023] Please see Figure 1-3 As shown, a road strength meter device for road surface testing includes a road strength meter body 1; two half-conical tubes 2 are symmetrically sleeved on the road strength meter body 1 to fix the two half-conical tubes 2; multiple cross grooves 3 are opened in the two half-conical tubes 2; a movable support plate 5 is rotatably connected in the cross grooves 3; a through groove 6 is opened in the movable support plate 5; an elastic membrane 7 is fixed in the through groove 6; a folded membrane 8 is fixed in the inner side of the movable support plate 5. The elastic membrane 7 and the folded membrane 8 form an encircling ring to receive falling particles. By changing the unfolding angle of the movable support plate 5, the unfolding area of ​​the receiving encircling ring can be increased, which can hold more particles generated during testing, and can transfer the particles generated after long-term testing, thereby improving the efficiency of continuous testing of roadbed materials.

[0024] The two semi-conical tubes 2 form a frustum shape, which avoids the falling space of particles and can accommodate more particles, thus reducing the number of times particles are transferred uniformly.

[0025] The folded membrane 8 is made of a non-elastic material; the elastic membrane 7 is made of an elastic material. The elastic membrane 7 keeps the movable support plate 5 in a retracted state, and the folded membrane 8 can also deform and remain in a retracted state. When it is necessary to unfold the membrane to receive and detect small stones and particles, the movable support plate 5 is counterweighted and unfolded to increase the receiving area, thereby allowing the particles generated during detection to be collected in a concentrated manner.

[0026] A baffle 4 is inserted into the cross groove 3 corresponding to the movable support plate 5. The baffle 4 restricts the movable support plate 5 from coming out of the cross groove 3, so that the rotation of the movable support plate 5 remains stable and will not disintegrate. It can be stably unfolded to collect the broken roadbed material.

[0027] The contact surfaces of the two semi-conical tubes 2 are symmetrically provided with grooves 9; magnetic plates 10 are inserted into the grooves 9; the contact surfaces of the magnetic plates 10 are magnetically attracted to each other, and the two semi-conical tubes 2 are precisely fitted onto the body 1 of the road strength tester through the magnetic connection of the two sets of mutually magnetically attracted magnetic plates 10.

[0028] The lower end of the road surface strength tester body 1 is fixed with multiple support corners 11; bolts 12 are inserted into the openings in the support corners 11. The support corners 11 and the bolts 12 can be stably fixed in the openings in the ground, so that they can remain stable for long-term use.

[0029] In the description of this specification, references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
