Description

Machine head pressurizing device of floor washing machine

Technical Field

The utility model relates to a machine head pressure device of floor cleaning machine.

Background

The floor cleaning machine is a common cleaning tool for cleaning the ground, has high cleaning efficiency, can greatly reduce the labor intensity of cleaning personnel, and wins the favor of the majority of users. The floor cleaning vehicle mainly cleans the ground by a brush disc in the machine head while walking, the pressure of the brush disc on the ground can obviously influence the cleaning effect, and the cleaning effect is better when the pressure is higher; however, in reality, the problems of energy conservation, endurance time and the like need to be considered, and for the common polluted ground, the good cleaning effect can be met only by the gravity of the disc brushing mechanism per se through practice verification; however, for heavily polluted floors which are not cleaned for a long time, additional pressure needs to be added properly to clean the floor efficiently and quickly.

The pressure of the floor washing machine head in the prior art on the ground is fixed and unchanged, and the actual conditions are not fully distinguished and processed, so that the brush disc always works under the action of the dead weight of the machine head, and the machine head is unfamiliar with severe pollution ground restraints, has poor cleaning effect and applicability and is to be further improved.

SUMMERY OF THE UTILITY MODEL

To the current situation of the above prior art, the utility model aims to solve the technical problem that a can adjust the aircraft nose pressure to the ground of floor cleaning machine aircraft nose in order to effectively promote the aircraft nose pressure device of floor cleaning machine of clean effect and suitability according to the dirty degree on ground is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the machine head pressurizing device of the floor washing machine is characterized by comprising two bearing seats arranged in front and at back, a rotating shaft arranged between the bearing seats in a transversely penetrating manner, a gear sleeved and fixed at the front end of the rotating shaft, a support arranged on the right side of the rotating shaft, a support frame transversely fixed on the support frame, a draw bar vertically and movably arranged in the support frame in a penetrating manner, and a connecting frame fixed at the lower end of the draw bar; the traction rod is provided with a spiral part on the outer peripheral surface, and the right side of the gear is meshed with the left side of the spiral part.

Preferably, the left side of the connecting frame is further provided with a seat plate, the left side of the seat plate is further fixed with a rotatable first connecting rod, the right side of the seat plate is further fixed with a rotatable second connecting rod, and the root of the second connecting rod is located above the root of the first connecting rod.

Preferably, a hand wheel is further fixed at the rear end of the rotating shaft.

Compared with the prior art, the utility model has the advantages of: the utility model discloses can adjust the ground pressure of scrubber aircraft nose according to the dirty degree on ground for brush dish on the aircraft nose can compress tightly subaerial with the pressure of the right, can be applicable to mild pollution's bottom surface and can be applicable to heavily polluted ground again, thereby has effectively promoted clean effect and suitability.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1, a machine head pressurizing device of a floor washing machine comprises two bearing seats 15 arranged in front and back, a rotating shaft 8 transversely inserted between the bearing seats 15, a gear 6 sleeved and fixed at the front end of the rotating shaft 8, a support 16 arranged on the right side of the rotating shaft 8, a support frame 17 transversely fixed on the support frame 16, a traction rod 3 vertically and movably inserted in the support frame 17, and a connecting frame 2 fixed at the lower end of the traction rod 3; a spiral portion 31 is formed on the outer peripheral surface of the drawbar 3, and the right side of the gear 6 is engaged with the left side of the spiral portion 31.

The left side of the connecting frame 2 is further provided with a seat board 10, the left side of the seat board 10 is further fixed with a rotatable first connecting rod 11, the right side of the seat board 10 is further fixed with a rotatable second connecting rod 12, and the root of the second connecting rod 12 is located above the root of the first connecting rod 11.

A hand wheel 9 is fixed at the rear end of the rotating shaft 8.

The installation method comprises the following steps: the connecting frame 2 and the seat plate 10 are both fixed on the top of the machine head 1, the support 16 and the two bearing seats 15 are both fixed on the top of the machine frame 13, and finally, the end parts of the first connecting rod 11 and the second connecting rod 12 are both rotatably fixed on the front end of the machine frame 13.

The working principle is as follows: the hand wheel 9 is held by hand and rotated to drive the rotating shaft 8 to rotate in the two bearing blocks 15, and then the traction rod 3 is driven to move up and down by virtue of the meshing relation between the gear 6 and the spiral part 31, so that the machine head 1 is driven to move up and down by virtue of the connecting frame 2 to realize the adjustment of the ground pressure; when the machine head 1 moves up and down, the first connecting rod 11 and the second connecting rod 12 can limit the machine head 1 to ensure the verticality of the machine head.

The utility model discloses can adjust the ground pressure of scrubber aircraft nose according to the dirty degree on ground for brush dish on the aircraft nose can compress tightly subaerial with the pressure of the right place, can be applicable to mild pollution's bottom surface and can be applicable to heavily polluted ground again, thereby has effectively promoted clean effect and suitability.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
