The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Unless otherwise specified, the front-rear direction in the present application is the longitudinal direction of the sweeper, i.e., the X direction; the left and right directions are the transverse directions of the sweeper, namely the Y directions; the up-down direction is the vertical direction of the sweeper, namely the Z direction.

Referring to fig. 1-4, a transition suction pipe installation assembly 100 for a sweeper is described, which can adjust the pitch angle of a transition suction pipe 4 in a horizontal plane, so that a user can flexibly adjust the opening orientation of the transition suction pipe 4, so that the transition suction pipe 4 can be quickly aligned with a suction pipe of a garbage can, and one transition suction pipe 4 can be respectively installed on two sides of each fixing bracket 1, so as to reduce the installation cost, and two transition suction pipes 4 can be adjusted at the same time, which is beneficial to improving the adjustment efficiency of the transition suction pipe 4.

As shown in fig. 1 to 4, a transition suction pipe installation assembly 100 for a sweeper truck according to an embodiment of the present application includes: a fixed bracket 1 and two mounting brackets.

The fixing bracket 1 is suitable for being installed on equipment to be installed, the equipment to be installed can be a fan of a sweeper, or the equipment to be installed can also be other equipment of the sweeper, so that the fixing bracket 1 is installed on the sweeper. As shown in fig. 1, the two ends of the fixing bracket 1 are both provided with first connecting portions, the first connecting portions are used for connecting with the mounting bracket, and the first connecting portions may be connecting plates with mounting holes 13, or other connecting structures.

Thus, each fixing bracket 1 has two first connecting portions, wherein two mounting brackets are respectively mounted at the two first connecting portions of the fixing bracket 1, and as shown in fig. 1 and 2, one mounting bracket is respectively mounted at both ends of each fixing bracket 1. It should be noted that, the mounting bracket and the fixing bracket 1 can be fixedly connected through a threaded fastener, so that when the threaded fastener is loosened, the mounting bracket and the fixing bracket 1 can be driven to move relatively, or the mounting bracket is detached from the fixing bracket 1, and when the threaded fastener is tightened, the mounting bracket and the fixing bracket 1 are connected into a whole.

Two installing support symmetries set up in the both ends of fixed bolster 1, and like this, two installing supports can the same mode fixed mounting in the fixed bolster, do benefit to and reduce installation time, reduce installation cost, and install in fixed bolster 1 back at two installing supports, the weight at the both ends of fixed bolster 1 is comparatively even for fixed bolster 1 is installing behind the motor sweeper, and the action of gravity at 1 both ends of fixed bolster is balanced, makes fixed bolster 1 have more stable operating condition.

The mounting bracket and the first connecting portion are rotatably matched around the first axis, namely the mounting bracket can rotate around the first axis relative to the first connecting portion so as to rotate relative to the fixing bracket 1, and further adjust the angle at which the mounting bracket is located, such as the pitching angle of the mounting bracket.

Wherein the first axis extends in the left-right direction of the fixed bracket 1, i.e. the first axis extends in the transverse direction of the fixed bracket 1. In this way, the mounting bracket enables adjustment of the pitch angle when the mounting bracket is rotated about the first axis relative to the first connection portion. The mounting bracket has and is used for installing transition straw 4, wherein, can pass through threaded fastener fixed mounting in the mounting bracket with transition straw 4 to make transition straw 4 can install fast and dismantle, do benefit to and improve the installation effectiveness.

Therefore, the transition suction pipe 4 can be fixedly arranged on the mounting bracket, and when the mounting bracket rotates relative to the fixed bracket 1, the transition suction pipe 4 can synchronously move along with the mounting bracket, namely, when the mounting bracket adjusts the pitching angle relative to the fixed bracket 1, the angle of the transition suction pipe 4 can also be effectively adjusted.

In specific execution, when the angle of the transition suction pipe 4 needs to be adjusted, the threaded fastener between the mounting bracket and the fixing bracket 1 is firstly adjusted to be loose, the mounting bracket and the transition suction pipe 4 are driven to rotate relative to the fixing bracket 1, so that the opening of the transition suction pipe 4 is rotated to a target position, the transition suction pipe 4 is conveniently aligned with the suction pipe of the dustbin, and after the transition suction pipe 4 is aligned and installed, the threaded fastener is screwed down, so that the transition suction pipe 4 is kept at the position.

From this, through foretell structure setting, can adjust the relative angle of transition straw 4 and fixed bolster 1, the regulative mode is simple, simple to operate, and the straw of the transition straw 4 of being convenient for adjust and dustbin is adjusted well with one heart fast, and the installation and debugging is simple, and is lower to operating personnel's technical skill level requirement, and the installation accuracy requirement to the part is low, and the cost is lower relatively, has greatly improved assembly and debugging efficiency.

And the transition straw installation component 100 of this application can install two transition straws 4 simultaneously, and two transition straws 4 are installed respectively in the both ends of fixed bolster 1, and two transition straws 4 can extend the left and right sides of motor sweeper respectively to link to each other with the straw of two dustbin simultaneously, do not need every transition straw 4 all to set up solitary mounting structure, do benefit to and reduce installation cost, and convenient the regulation. Wherein, the angle that two transition sipper pipes 4 were located can be adjusted simultaneously, perhaps the angle that two transition sipper pipes 4 were located can be adjusted alone, and structural flexibility is good, and it is more convenient to use.

According to transition straw installation component 100 for motor sweeper of the embodiment of the application, the relative angle of installing support and fixed bolster 1 around first axis is nimble adjustable, so that the user adjusts the angle that transition straw 4 locates according to actual need, be convenient for realize adjusting well fast with the straw of dustbin, and a transition straw 4 can be installed respectively at the both ends of fixed bolster 1, but two transition straws 4 simultaneous control, also can adjust alone, the structure sets up in a flexible way, and do benefit to and reduce installation cost, and the assembly efficiency is improved.

In some embodiments, the two first connecting portions of the fixing bracket 1 are oppositely disposed along the left-right direction of the fixing bracket 1, as shown in fig. 1 and 2, the fixing bracket 1 has a left-right symmetrical structure, that is, the first connecting portions on both sides of the fixing bracket 1 are identically disposed and are oppositely disposed along the left-right direction, and thus, the two mounting brackets can be respectively mounted on the two first connecting portions in the same manner, thereby improving the mounting efficiency of the mounting bracket and the fixing bracket 1. And after the two mounting brackets are mounted on the fixed bracket 1, the arrangement forms of the two mounting brackets are consistent, so that the overall structure of the transition suction pipe mounting assembly 100 is more regular, and the structural weights of the two sides of the fixed bracket 1 are more balanced.
