[0022] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: a grille dirt removal device, including a dirt blocking gate 1, a dirt blocking grille 101 is fixedly connected to the inner wall of the dirt blocking gate 1, an upper support plate 2 is fixed on the dirt blocking gate 1, support slide bars 201 are symmetrically fixed below the upper support plate 2, an adjustment seat 3 is slidably installed on the support slide bar 201, a telescopic connecting rod 4 is fixed behind the adjustment seat 3, a support plate 5 is fixed at the other end of the telescopic connecting rod 4, a plurality of rake hooks 6 are fixed on the support plate 5 by bolts, and triangular guide plates 7 are fixed on both sides of the rake hooks 6 on the support plate 5 by bolts.

[0024] In this embodiment, the rake hook 6 is inserted into the gap between the dirt grilles 101, so that the upward movement of the adjustment seat 3 will drive the support plate 5 to move upward, and the upward movement of the support plate 5 will simultaneously drive the rake hook 6 and the triangular guide plate 7 to move upward. The rake hook 6 is inserted into the gap of the dirt grille 101, so that the dirt in the dirt grille 101 that is stuck can be scraped off. When encountering a horizontal grille, the triangular guide plate 7 will first contact the horizontal grille. Since the upper and lower surfaces of the triangular guide plate 7 are both inclined surfaces, and the adjustment seat 3 and the support plate 5 are connected by the telescopic connecting rod 4, the triangular guide plate 7 will drive the support plate 5 to move forward and compress the telescopic connecting rod 4, driving the rake hook 6 to move out of the gap between the grilles, so that the device can move upward smoothly. After climbing over the horizontal grille, the support plate 5 will once again drive the rake hook 6 to reset and reinsert into the gap between the grilles, thereby continuously removing the dirt in the gap between the grilles.

[0025] Among them, in order to achieve the purpose of driving the adjustment seat 3 to move up and down, the present device adopts the following technical scheme: a lower support plate 202 is fixed at the lower end of the support slide bar 201, a threaded adjustment rod 203 is rotatably installed between the upper support plate 2 and the lower support plate 202, a motor 204 is fixed on the upper support plate 2, the output end of the motor 204 is fixed to the threaded adjustment rod 203, a threaded sleeve 302 is embedded and installed at the center of the adjustment seat 3, and a through hole 301 is opened in the adjustment seat 3 and on both sides of the threaded sleeve 302, the through hole 301 is slidably matched with the support slide bar 201, and the threaded sleeve 302 is threadedly matched with the threaded adjustment rod 203.

[0026] By starting the motor 204, the threaded adjustment rod 203 can be driven to rotate. The threaded adjustment rod 203 is threadedly matched with the threaded sleeve 302, so that the rotation of the threaded adjustment rod 203 can drive the adjustment seat 3 to move up and down. The movement of the adjustment seat 3 further drives the rake hook 6 and the triangular guide plate 7 to move. The through hole 301 is slidably matched with the supporting slide bar 201, so that the adjustment seat 3 can only move up and down.

[0027] Among them, in order to achieve the purpose of consolidating the rake hook 6 and the triangular guide plate 7, the present device is implemented by adopting the following technical scheme: a return spring 401 is sleeved on the telescopic connecting rod 4, a connecting groove 501 is opened in the support plate 5, a first connecting seat 602 is consolidated on the front side of the rake hook 6, a second connecting seat 701 is consolidated on the front side of the triangular guide plate 7, nuts 8 are embedded and installed in the first connecting seat 602 and the second connecting seat 701, and a barb 601 is consolidated on the rear end of the rake hook 6.

[0028] The return spring 401 can provide a certain thrust for the support plate 5. After the triangular guide plate 7 climbs over the horizontal grille, the return spring 401 will push the support plate 5 to move backward, thereby driving the rake hook 6 and the triangular guide plate 7 to be reinserted into the grille gap. The bolt is passed through the connecting groove 501 from the bottom of the support plate 5 and screwed into the nut 8, so that the second connecting seat 701 and the first connecting seat 602 are both fixed to the support plate 5. The barb 601 is located at the front end of the rake hook 6. Since the connecting groove 501 is matched with the bolt, the number and density of the rake hook 6 can be freely adjusted according to the density of the grille, so that the rake hook 6 can be inserted into the gap between the grilles, which can prevent the strip of dirt inserted on the rake hook 6 from slipping off.

[0029] The working principle and use process of the utility model are as follows: when using the device, it is necessary to install the device to a suitable position, start the motor 204 to drive the adjustment seat 3 to move upward, and the upward movement of the adjustment seat 3 will synchronously drive the rake hook 6 and the triangular guide plate 7 to move upward. When the triangular guide plate 7 encounters a horizontally placed grille, it will drive the support plate 5 to move backward, and the backward movement of the support plate 5 will drive the rake hook 6 to move, so that the rake hook 6 moves forward from the grille gap, so that the rake hook 6 can continue to move upward, and when the rake hook 6 and the triangular guide plate 7 climb over the horizontally placed grille, under the push of the return spring 401, the rake hook 6 and the triangular guide plate 7 will be reinserted into the grille gap, and the rake hook 6 will continue to move upward, so that the strip-shaped dirt stuck in the grille gap can be cleaned up.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
