DETAILED DESCRIPTION
[0020] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings:
[0021] Example:
[0022] like Figures 1 to 6 As shown, the utility model provides a sand and gravel funnel, comprising:
[0023] The upper funnel 1 is hingedly provided with a support rod 10 for supporting and fixing; specifically, the support rod 10 is fixed to the upper funnel 1 through a fixing sleeve;
[0024] The lower funnel 2 is detachably connected to the lower end of the upper funnel 1, and the lower funnel 2 can be detachably replaced with different lower diameters;
[0025] The adjusting mechanism 3 is provided at the lower end of the upper funnel 1 and is hinged to the support rod 10 through the hinge rod 4 so as to adjust the angle between the support rod 10 and the upper funnel 1, thereby adjusting the height of the funnel.
[0026] As another embodiment of the present application, Figure 2 and Figure 5 As shown, the lower end opening of the upper funnel 1 of the present application is provided with a plug-in groove 11, and a plurality of studs 5 are provided on the plug-in groove 11. The upper end of the lower funnel 2 is provided with a plug-in portion 21, and a plurality of L-shaped through holes 22 are provided in the plug-in portion 21. The plug-in portion 21 is plugged into the plug-in groove 11 so that the stud 5 is located in the L-shaped through hole 22. The lower funnel 2 is rotated to move the stud 5 to the end of the L-shaped through hole 22.
[0027] See also Figure 2 The present application further includes a pre-tightening bolt 7, which is threadedly connected to the stud 5. It also includes a limiting post 6, which is disposed in the insertion slot 11. The present application includes two studs 5 and two limiting posts 6, which are circumferentially arranged in the insertion slot 11, so that the four L-shaped through holes 22 can be plugged into the studs 5 and limiting posts 6 and rotated to fix the lower funnel 2 to the upper funnel 1.
[0028] Furthermore, a movable plate (not shown) is provided at the lower portion of the lower funnel 2 of the present application, so that the cylindrical lower opening of the lower funnel 2 can be slid open and closed by providing the movable plate.
[0029] See also Figure 3 and Figure 4The adjustment mechanism 3 of the present application includes a fixed rod 31, a sliding ring 32, a fixed ring 33, and an adjusting screw 34. There are multiple fixed rods 31, which are fixed to the upper funnel 1. The fixed ring 33 is fixedly connected to the end of the fixed rod 31. The sliding ring 32 is slidably arranged on the fixed rod 31. One end of the hinged rod 4 is hinged to the sliding ring 32. The adjusting screw 34 is rotatably arranged on the fixed ring 33, and one end of the adjusting screw 34 is threadedly connected to the sliding ring 32. Rotating the adjusting screw 34 drives the sliding ring 32 to move relative to the fixed ring 33, so that the hinged rod 4 pushes the support rod 10 to rotate on the upper funnel 1, thereby simultaneously adjusting the angle between the three support rods 10 and the upper funnel 1 to adjust the height of the lower caliber of the funnel. This allows the test height to be adjusted according to the situation when replacing the lower funnel 2 with a different lower caliber. Furthermore, a knob is provided at the end of the adjusting screw 34. The adjusting screw 34 is provided with a limiting ring for limiting the adjusting screw 34 on the fixing ring 33 .
