[0001] The present invention relates to the technical field of vehicle testing, and in particular to an automatic weighing and counting method and device for a sanitation sweeper. Background Art

[0002] The sanitation sweeper is a new type of efficient cleaning equipment that integrates road cleaning, garbage collection and transportation. The sweeping rate is an assessment indicator of the sanitation sweeper, so it is necessary to test the sweeping rate of the sanitation sweeper. At present, the garbage samples are spread manually, which is inefficient.

The outer wall of the cylinder is provided with a plurality of grooves. When moving, the rotating shaft can be driven to rotate by the rotation of the moving wheel, and the rotating shaft drives the cylinder to rotate. The cylinder discharges the sand and gravel inside the groove. Since the space of the groove remains consistent, the spreading is more uniform. After the spreading is completed, the spread garbage is cleaned by a sweeper. After the cleaning is completed, the garbage recycling device is used to recycle the residual garbage that has not been cleaned up.

Therefore, two blocking assemblies 301 are arranged to block the spread sand and gravel within the cleaning range of the sweeper body 101 as much as possible.

[0055] The vertical plate 302 is fixedly connected to the front trolley 104 and is located at the bottom of the front trolley 104; the inclined plate 303 is fixedly connected to the vertical plate 302 and is located on one side of the vertical plate 302. The two vertical plates 302 block the sand and gravel thrown out to the two sides, and the two inclined plates 303 are used to block the sand and gravel thrown out in the inclined direction in front of the front trolley 104.

[0056] The automatic weighing and counting device of the sanitation sweeper described in this embodiment, the two vertical plates 302 are used to block the sand and gravel thrown out to the two sides, and the two inclined plates 303 are used to block the sand and gravel thrown out in the inclined direction in front of the front trolley 104, so as to block the scattered sand and gravel within the cleaning range of the sweeper body 101 as much as possible.

[0057] The fourth embodiment of the present application is:

[0058] See also Fig.14,in, Fig.14 4 is a flow chart of the fourth embodiment of the present invention.

[0059] The present invention provides an automatic weighing and counting method for a sanitation sweeper, comprising:

[0060] S1 weighs a preset amount of sand and gravel, and records the mass of the sand and gravel;

[0061] S2: installing the spreading assembly 102 at the head of the sweeper body 101, and installing the collecting and weighing assembly 103 at the tail of the sweeper body 101;

[0062] S3 puts all the sand and gravel into the spreading box 105;

[0063] S4 starts the cleaning vehicle body 101 to move, opens the valve 107, and starts the reciprocating driving mechanism 109 and the motor;

[0064] S5 The sand and gravel in the spreading box 105 falls along the discharge hopper 106 and is randomly thrown to the ground by the spreading disc 112;

[0065] S6 The sweeper body 101 cleans the gravel on the ground, and the collecting and weighing component 103 cleans and weighs the gravel that has not been cleaned by the sweeper body 101, and calculates the cleaning rate of the sweeper body 101.

[0066] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
