[0034] like Figure 1-5 As shown, the utility model preferably provides a switch device for a mortar pumping system, which includes at least two fixed plates 10, a pull-out plate 20 and a first closing plate 30;

[0035] A pumping pipe 60 is connected to each of the fixing plates 10, and a support member 11 is provided between two adjacent fixing plates 10, so that a drawing channel is formed between the two adjacent fixing plates 10, and the length direction of the drawing channel is the first direction;

[0036] The pull-out plate 20 is disposed in the pull-out channel, and the pull-out plate 20 reciprocates in the pull-out channel along the first direction, and a through hole 21 adapted to the pumping pipe 60 is disposed on the pull-out plate 20;

[0037] The first closing plate 30 is arranged on the pull-out plate 20, and an extension portion 13 extending outward is provided at one end of the fixed plate 10 close to the first closing plate 30. The pull-out plate 20 moves along the first direction, and the first closing plate 30 is connected to the extension portion 13, so that the two adjacent pumping pipes 60 are connected to each other, and the extension portion 13 limits the displacement of the pull-out plate 20 along the first direction through the first closing plate 30.

[0038] Based on the above technical features, through the arrangement of the fixed plate 10, the pull-out plate 20, the first closed plate 30 and the support member 11; wherein, the support member 11 props up the two adjacent fixed plates 10, so that a pull-out channel is formed between the two adjacent fixed plates 10, and the pull-out plate 20 is placed in the pull-out channel, so that the pull-out plate 20 moves back and forth in the pull-out channel along the first direction; wherein, the pull-out plate 20 is provided with a through hole 21 adapted to the pipe mouth of the pumping pipe 60, and by adjusting the position of the through hole 21, the two adjacent pumping pipes 60 are in a connected state or in a blocked state; wherein, through the arrangement of the first closed plate 30 and the extension part 13, when the pull-out plate 20 moves along the first direction, the first closed plate 30 is connected to the extension part 13, and the movement of the first closed plate 30 is restricted. At this time, the through hole 21 on the pull-out plate 20 moves to the preset position, and the two adjacent pumping pipes 60 are connected to each other.

[0039] As some embodiments of the utility model, a first spring member 31 is provided on the first closing plate 30, one end of the first spring member 31 is connected to the pull-out plate 20, and the other end is connected to the first closing plate 30, the pull-out plate 20 moves along the first direction, the first closing plate 30 is connected to the extension portion 13, the first spring member 31 is in a compressed state, and the first closing plate 30 gradually approaches the pull-out plate 20. By setting the first closing plate 30 and the first spring member 31, when the pull-out plate 20 moves along the first direction, it drives the first closing plate 30 to move. When the first closing plate 30 moves a certain displacement, the first closing plate 30 is connected with the extension part 13, so that the movement of the first closing plate 30 is restricted. At the same time, the first closing plate 30 gradually approaches the pull-out plate 20, and the first spring member 31 is in a compressed state, ensuring the stability of the connection between the first closing plate 30 and the extension part 13. At this time, the two adjacent pumping pipes 60 are interconnected through the through hole 21, so that the mortar pumping system is in an open state, which effectively realizes the restriction of the displacement of the pull-out plate 20 along the first direction, and further ensures that the pull-out plate 20 of the device will not move excessively, resulting in the mortar pumping system being unable to open normally.

[0040] As some embodiments of the utility model, the second closing plate 40 and the second spring member 41 are also included. The second closing plate 40 is arranged on the pull-out plate 20 and is away from the first closing plate 30.

[0046] As some embodiments of the utility model, the pull-out plate 20 is provided with handles 22 at both ends along the first direction for facilitating the user to apply force. The provision of the handles 22 facilitates the user to apply external loads to the pull-out plate 20 when the user controls the opening or closing of the mortar pumping system by moving the pull-out plate 20, so that the reciprocating movement of the pull-out plate 20 along the first direction is easily achieved.

[0047] In summary, the embodiment of the utility model provides a switch device for a mortar pumping system, which is provided by a fixed plate 10, a pull-out plate 20, a first closing plate 30 and a support member 11, wherein the support member 11 props up two adjacent fixed plates 10, so that a pull-out channel is formed between the two adjacent fixed plates 10, and the pull-out plate 20 is placed in the pull-out channel. The support member 11 allows a gap to exist between the pull-out plate 20 and the pull-out channel, so as to avoid the pull-out plate 20 being unable to move due to the vertical load of the pumping pipe 60 above, so that the pull-out plate 20 reciprocates in the pull-out channel along the first direction; wherein the pumping pipe 60 is provided on the pull-out plate 20 The through hole 21 is adapted to the pipe mouth. By adjusting the position of the through hole 21, the two adjacent pumping pipes 60 are placed in a connected state or in a blocked state, thereby preventing the pull-out plate 20 from moving excessively during the movement. Among them, through the arrangement of the first closing plate 30 and the extension portion 13, when the pull-out plate 20 moves along the first direction, the first closing plate 30 is connected to the extension portion 13, and the first closing plate 30 cannot move. At this time, the through hole 21 on the pull-out plate 20 moves to a preset position, thereby preventing the pull-out plate 20 from moving out of place during the movement, so that the switch device can achieve precise control of the opening and closing of the mortar pumping system.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention.
