[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-5The utility model provides a technical solution: a sand filling cylinder for detecting the compaction degree of roadbed and pavement, comprising a sand filling cylinder 1, a positive funnel 4 is installed at the bottom inner side of the sand filling cylinder 1, a card block 5 is installed at the bottom of the positive funnel 4, a rotating part is installed on the top of the positive funnel 4, a connecting cylinder 10 is installed at the bottom of the sand filling cylinder 1, a limiting cylinder 11 is installed inside the connecting cylinder 10, a reverse funnel 13 is installed inside the limiting cylinder 11, a buffer is installed on the outside of the connecting cylinder 10, a movable frame 6 is symmetrically installed on the top of the connecting cylinder 10, a transmission gear 9 is installed at the bottom of one end of the movable frame 6, and a connecting piece is meshed and connected on the outside of the transmission gear 9.

[0019] The rotating part includes one end of a horizontal pin 2 that is rotatably installed on the inner edge of the sand filling cylinder 1, and the other end of the horizontal pin 2 is slidably installed inside the other side of the sand filling cylinder 1. The switch for measuring the downward flow of sand can more easily control the flow of measuring sand. A baffle 3 is installed near the sliding end of the horizontal pin 2 to prevent the measuring sand from overflowing.

[0020] The buffer member includes a telescopic rod 7 symmetrically installed on the outside of the connecting tube 10, and a support spring 8 is sleeved on the outside of the telescopic rod 7. The telescopic rod 7 and the support spring 8 are installed at the bottom end of one side of the movable frame 6 to provide buffering force for the process of pressing the sand filling tube 1 downward.

[0021] The connecting member includes a rack 12 symmetrically installed on the outside of the limiting cylinder 11 and the inside of the connecting cylinder 10. The transmission gear 9 is engaged with the rack 12 to provide power for lifting the limiting cylinder 11 and the anti-funnel 13.

[0022] The bottom of the sand filling cylinder 1 is slidably installed inside the limiting cylinder 11, and the component connection process is smoother. The movable frame 6 is clamped on the outside of the sand filling cylinder 1, and the connection between the components is tighter. The bottom of the limiting cylinder 11 and the anti-funnel 13 are in contact and connected with the bottom end of the connecting cylinder 10 to prevent the measured sand from overflowing.

[0023] A base plate 14 is installed at the bottom end of the connecting tube 10 to facilitate subsequent operations by the staff.

[0024] Example 2: Please refer to Figure 1-5The utility model provides a technical solution: a sand filling barrel 1 for detecting the compaction degree of roadbed and pavement. By pouring measuring sand into the sand filling barrel 1 and toggling one end of the cross pin 2 to both sides, it can be used as a switch for the measuring sand to flow downward, which can make it easier to control the flow of measuring sand. At the same time, a baffle 3 is installed on the end close to the sliding of the cross pin 2 to prevent the measuring sand from overflowing during the sliding of the cross pin 2, thereby increasing the accuracy of measurement. Then the staff places the sand filling barrel 1 on the top of the movable frame 6 by the handle, and presses the movable frame 6 downward by gravity. The movable frame 6 simultaneously drives the telescopic rod 7 and the supporting spring 8 to contract, providing a buffer force for the sand filling barrel 1. The movable frame 6 also drives the transmission gear 9 during the downward movement. The sand filling cylinder 1 drives the limiting cylinder 11 and the reverse funnel 13 to move in the opposite direction, so that the reverse funnel 13 and the positive funnel 4 are docked on the outside of the device. During the docking process, the card block 5 is cooperated at the same time. The inner side of the card block 5 extends into the interior of the reverse funnel 13, and the outer side wraps the interface of the reverse funnel 13. The connection is very tight to prevent the measuring sand from flowing out from the connection gap. Through the continuous downward pressure of the sand filling cylinder 1, the transmission gear will slide into the chute set at the bottom of the rack 12. At the same time, the reverse funnel 13 and the positive funnel have been docked. The sand filling cylinder 1 drives the limiting cylinder 11 and the bottom of the reverse funnel 13 to be close to the top of the substrate. The components cooperate with each other to make the component connection tighter and the measurement more accurate.
