[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 3 As shown, an embodiment of the utility model provides a negative pressure particle suction device, which includes a dust suction piece 10, a connecting component 20 and a control component 30. The dust suction piece 10 includes a negative pressure piece 11 and a dust suction head 12, and the dust suction head 12 is arranged on the vibrating screen. The connecting component 20 includes a connecting pipe 21 and a collecting pipe 22. The negative pressure piece 11 and the dust suction head 12 are respectively connected to the connecting pipe 21, and the connecting pipe 21 is arranged vertically. The lower end of the connecting pipe 21 is connected to the collecting pipe 22. The control component 30 includes a first opening and closing piece 31 and a second opening and closing piece 32. The first opening and closing piece 31 is arranged at the connection between the dust suction head 12 and the connecting pipe 21, and the first opening and closing piece 31 has a first open state and a first closed state. The second opening and closing piece 32 is arranged at the connection between the connecting pipe 21 and the collecting pipe 22, and the second opening and closing piece 32 has a second open state and a second closed state.

[0028] The negative pressure particle suction device provided in this embodiment is applied, and the negative pressure particle suction device includes a dust suction piece 10, a connecting component 20 and a control component 30. The dust suction head 12 in the dust suction piece 10 is arranged on the vibrating screen, and the dust suction head 12 is connected with the negative pressure piece 11. When the negative pressure piece 11 is working, the large particle material on the vibrating screen can be negatively adsorbed by the dust suction head 12. The negative pressure piece 11 and the dust suction head 12 are respectively connected with the connecting pipe 21, so that the large particle material can be passed into the connecting pipe 21. Since the lower end of the connecting pipe 21 is connected with the collecting pipe 22, the large particle material can be discharged into the collecting pipe 22, and then the large particle material can be collected. Among them, in order to ensure the structural reliability of the negative pressure particle suction device, the first opening and closing member 31 in the control component 30 is set at the connection between the dust collector head 12 and the connecting pipe 21, and the second opening and closing member 32 in the control component 30 is set at the connection between the connecting pipe 21 and the collecting pipe 22. The first opening and closing member 31 has a first open state and a first closed state, thereby controlling the connection or closure between the dust collector head 12 and the connecting pipe 21, and the second opening and closing member 32 has a second open state and a second closed state, thereby controlling the connection or closure between the connecting pipe 21 and the collecting pipe 22. Furthermore, when the negative pressure member 11 is started, the first opening and closing member 31 is in the first opening state, and the second opening and closing member 32 is in the second closing state, so that the large particle materials in the vibrating screen are discharged into the connecting pipe 21 by the dust collecting head 12; when the negative pressure member 11 is closed, the first opening and closing member 31 is in the second closing state, and the second opening and closing member 32 is in the second opening state, so that the large particle materials in the connecting pipe 21 are discharged into the collecting pipe 22; and then, when the vibrating screen is used to separate the large particle materials, the dust collecting member 10 is used to suck the large particle materials into the collecting pipe 22 of the connecting component 20, and the first opening and closing member 31 and the second opening and closing member 32 are alternately opened and closed, so that it is convenient to realize the negative pressure effect to absorb the large particle materials, and to discharge the large particle materials into the collecting pipe 22, thereby ensuring the separation efficiency of the vibrating screen and facilitating the collection of the large particle materials.

[0029] In this embodiment, the negative pressure particle suction device further includes a control box, a power-off delay device and a solenoid valve, the control box is electrically connected to the power-off delay device, the power-off delay device is electrically connected to the solenoid valve, and the solenoid valve is electrically connected to the first opening and closing member 31 and the second opening and closing member 32. With the above structure, by setting the control box, the power-off delay device and the solenoid valve, the control box is electrically connected to the power-off delay device, the power-off delay device is electrically connected to the solenoid valve, and the solenoid valve can control the first opening and closing member 31 and the second opening and closing member 32 to open or close, so that the control box plays a control role, and the power-off delay device can play a delay role on the first opening and closing member 31 and the second opening and closing member 32, so that the dust collector head 12 and the negative pressure member 11 can be used to suck the large particles on the vibrating screen for a period of time, so as to facilitate the continuous suction of the large particles on the vibrating screen.

[0030] In this embodiment, a filter is provided at the connection between the connecting pipe 21 and the negative pressure member 11. With the above structure, by providing a filter at the connection between the connecting pipe 21 and the negative pressure member 11, it is convenient for the dust collector 12 to be connected with the connecting pipe 21 and the connecting pipe 21 to be connected with the negative pressure member 11 when the first opening and closing member 31 is opened. The filter can avoid the problem that large particles enter the connecting pipe 21 and are then adsorbed by the negative pressure member 11, resulting in failure to collect the large particles, so that the large particles are adsorbed on the filter when the negative pressure member 11 is working. When the first opening and closing member 31 is in the first closed state and the second opening and closing member 32 is in the second open state, the negative pressure member 11 stops working, and the large particles on the filter are no longer adsorbed by the negative pressure member 11, and then fall into the collection pipe 22, so that the large particles are collected by the collection pipe 22.

[0031] It should be noted that the power-off delay device can delay the first opening and closing member 31 and the second opening and closing member 32 , and the control box is provided with an operation button for controlling the solenoid valve to control the first opening and closing member 31 and the second opening and closing member 32 . Specifically, the staff presses the operation button to make the power-off delay device work, and the solenoid valve controls the first opening and closing piece 31 to be in the first opening state, so that the dust collector head 12 is connected to the connecting pipe 21, and the connecting pipe 21 is connected to the negative pressure piece 11, and the second opening and closing piece 32 is in the second closing state, so that the connecting pipe 21 and the collecting pipe 22 are not connected, which is convenient for sucking large particles into the connecting pipe 21. Due to the effect of the filter, large particles can be prevented from being sucked into the negative pressure piece 11, and large particles in the collecting pipe 22 can be prevented from being sucked into the connecting pipe 21 by the collecting pipe 22 by the negative pressure piece 11. In this way, the collecting pipe 22 can be used to collect. When the power-off delay device stops working after working for a period of time, the solenoid valve controls the first opening and closing piece 31 to be in the first closing state, so that the dust collector head 12 is not connected to the connecting pipe 21. At this time, the negative pressure piece 11 does not work, and the second opening and closing piece 32 is in the second opening state, so that the large particles sucked into the connecting pipe 21 can enter the collecting pipe 22.

[0032] In this embodiment, the negative pressure particle absorption device also includes a sealing ring, and the side wall of the sealing ring fits the filter screen. With the above structure, by setting the sealing ring, it can be ensured that the sealing ring fits the filter screen, and the negative pressure member 11 can play a role of negative pressure absorption, thereby ensuring that the large particles in the vibrating screen are absorbed.
