[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting a sliding connection, the handle drives the scraper to move synchronously, gathering the soil on the surface of the tray, which facilitates soil collection and makes the test process more convenient;

[0019] 2. By setting up a sand-filling cylinder with a positioning function, the position of the sand-filling cylinder can be quickly fixed, improving the convenience of the test while ensuring the accuracy of the test;

[0020] 3. By setting up a tray that can be fixed to the ground, the stability of the test process is increased, while also ensuring the accuracy of the test. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, a sand-filling test apparatus includes a tray 1, a sand-filling cylinder 2, a scraper 3, and a handle 4.

[0027] likeFigure 2 、 Figure 3 As shown in the figure, the tray 1 is horizontally placed on the ground, the center of the tray 1 is provided with a sampling hole 11, and the lower end surface of the tray 1 is provided with a positioning ring 12 surrounding the sampling hole 11, which is used to pierce the ground to fix the tray 1, and the positioning ring 12 also serves as a reference, so that the position of the positioning ring 12 can be referred to when digging the test pit, making the digging process of the test pit more convenient.

[0028] As shown in the figure, Figure 2 、 Figure 3 The tray 1 is provided with a baffle ring 13 extending upward around the periphery, and the outer wall of the baffle ring 13 is provided with a fixed plate 14, and the fixed plate 14 is vertically and slidingly connected with a fixed needle 15, so that when the tray 1 is placed on the ground, the fixed needle 15 can be pressed to pierce the ground, thereby fixing the tray 1 and increasing the stability of the tray 1 during testing.

[0029] As shown in the figure, Figure 2 、 Figure 3 The sand pouring cylinder 2 is vertically arranged on the tray 1 and surrounds the sampling hole 11. The upper end of the sand pouring cylinder 2 is flared to facilitate pouring standard sand into the sand pouring cylinder 2. The outer wall of the sand pouring cylinder 2 is provided with a recording card 21, which is convenient for recording data each time.

[0030] As shown in the figure, Figure 2 、 Figure 3 The scraper 3 is L-shaped and abuts against the surface of the tray 1, and the lower end side walls of the two sides of the scraper 3 are both provided with a shovel 31 inclinedly arranged. The handle 4 is slidingly connected to the baffle ring 13 and connected to the scraper 3.

[0031] As shown in the figure, Figure 2 、 Figure 3 The lower end side wall of the sand pouring cylinder 2 is provided with an outer edge 22 abutting against the tray 1, and the outer edge 22 is provided with a gap 23 for embedding the scraper 3, which can make the sand pouring cylinder 2 flatly placed on the tray 1 and achieve the limiting of the sand pouring cylinder 2.
