Description

Water-saving rake

Technical Field

The invention belongs to the field of environment-friendly cleaning tools, and particularly relates to a water-saving rake.

Background

At present, passages, doorways and streets of a plurality of units are often cleaned by a cleaner dragging a rubber tube to wash the ground with water. Wash away dirt and a little mud on the ground. The water pressure in the rubber tube is higher, the flushing is very quick, and the water flow is very large. The sticky substances are attached to the ground and are difficult to wash away even if being washed away with water for a long time, or the sticky substances are continuously washed away for a long time when being rolled by wheels. It is also common to encounter small but slow moving stones on the ground. Under the condition, in the washing process of workers, due to the fact that time is long, water consumption is more than ten times of that of the general ground, tap water resources are greatly wasted, and work efficiency is low.

Disclosure of Invention

The invention aims to solve the problem that tap water is wasted when objects which cannot be washed away are washed away in the ground by high-pressure water in the prior art, and provides a water-saving rake.

The invention is realized by the following steps: the water-saving harrow comprises a shovel block, a broom, two end supports, a transverse support, a blocking device, a spring, a handle bar and a water spraying pipe. The two-end bracket is connected with the two ends of the transverse bracket. The shovel block and the broom are respectively hinged on two sides of the bracket at two ends. The water spray pipe is arranged in the pipe orifice at the front end of the handle bar. The rear end of the handle bar is provided with a switch. A rubber tube is connected behind the switch. The shovel block and the broom are respectively provided with a set of blocking device. The blocking and clamping devices of the shovel block and the broom are respectively arranged on the brackets at the two ends. Springs are arranged on the shovel block and the broom. The card blocking device comprises a rotating card and a resisting card. When the shovel block and the broom are not used, the shovel block and the broom rotate to the upper parts of the side edges of the brackets at the two ends around the hinges respectively. When the water is sprayed to wash the ground, a user holds the handle bar, turns on the switch and sprays water through the spray pipe to wash the ground. When attachments which are difficult to wash away by water appear on the ground in the water spraying and washing process, a user turns off the switch with one hand, puts down the shovel block, shovels the attachments on the ground by the shovel block, rotates the shovel block upwards, blocks the attachments by the resisting block, and turns on the switch to continuously wash the ground; when the ground has more stones and garbage and is slowly flushed away by water, the switch is closed, the broom is put down, the switch is opened after the stones and the garbage on the ground are swept away, and the ground is continuously flushed. And rotating clamps in the clamping blocking device are respectively arranged on the rotating shaft ends at one end of the shovel block and one end of the broom. A rotating shaft is transversely connected above the shovel block and the broom, and two sides of the bracket at two ends are respectively hinged with two ends of the rotating shaft on the shovel block and the broom.

The invention has the advantages that: a shovel block and a broom are arranged below one handle bar. The front of the handle is provided with a spray pipe, and the rear end of the handle is provided with a switch and a rubber pipe. When the switch is opened to flush the ground, the shovel block and the broom are both rotated and retracted. When the water is not used for washing the attachments and the stones, the switch is turned off, the shovel block is put down, the switch is twisted after the attachments and the stones are shoveled, and the ground can be washed continuously. When the ground has more small stones and more garbage, the switch can be turned off, the broom is put down to sweep the stones and the garbage, and then the switch is turned on to continuously flush the ground. Greatly shortens the time of water spraying to flush the land and saves a lot of tap water.

Detailed Description

In FIG. 1, the broom of the water-saving rake is retracted and the shovel block is put down. A handle bar 4 is connected and fixed on the upper side of the horizontal bracket 2. The handle bar 4 is a plastic tube. The sprinkler pipe 1 is also a section of plastic pipe. The spray pipe 1 is arranged in the front end pipe orifice of the handle bar 4 and is fixed with the handle bar in a sealing way. The rear end of the handle bar is provided with a switch 5, and the rear side of the switch 5 is connected with a rubber tube 6. The switch 5 is provided with a twist handle. The left side of the switch is provided with a section of connecting pipe with screw threads which is screwed into a threaded pipe arranged at the rear end of the handle. The right end of the switch 5 is provided with a connecting section with an anti-slip bevel gear ring, the connecting section is forcibly embedded into the left end port of the rubber tube, and the rubber tube is hooped by a metal wire. The connection of such a switch with a hose is prior art. When the switch is turned on, high-pressure water is flushed out from the water source position, through the rubber tube, the switch and the handle pipe and from the spray pipe 1.

Two ends of the transverse bracket 2 are respectively connected with a bracket 7 at two ends. Two rotating shafts 9 are arranged below the brackets 7 at the two ends. The left rotating shaft 9 in fig. 1 is a rotating shaft connected above the shovel block 11. The shovel block 11 is put down and landed, and is used for shoveling off ground attachments, stones and mud lumps. At this time, the lower side of the rotating shaft on the shovel block and the upper back side of the shovel block 11 lean against the lower side of the transverse bracket 2. The rotating shaft 9 above the shovel block 11 penetrates through the brackets 7 at the two ends. The rotating clamp 13 is connected and arranged on the end of the rotating shaft 9 which penetrates through the brackets 7 at the two ends at the upper end of the shovel block. The right end of the resisting card 14 is arranged on the upper right of the brackets at the two ends by a shaft pin 15. The front end of the resisting card 14 is transversely propped against the upper right side of the rotating card 13. The shaft pin below the support card is provided with a torsion spring, i.e. a torsion spring, which enables the support card to rotate counterclockwise, and the torsion spring and the mounting on the shaft pin are widely used in the prior art and are not described in detail herein, and the spring on the support card is not shown in the figures. A block 12 is arranged on the supports at the two ends of the lower edge of the butt clamp 14. Abutment 12 is intended to define the counterclockwise rotational position of catch 14. At this time, the right side, the upper side and the lower side of the rotating shaft of the shovel block are all propped against, and the shovel block is positioned.

In fig. 1, a broom is arranged at the right side of the transverse bracket 2. The broom consists of a broom shell 8 and a broom brush 3 arranged in the broom shell. A torsion spring, namely a spring 10 in figure 1, is arranged on a rotating shaft 9 connected with a broom shell 8 of the broom. The broom shell 8 of the broom is arranged at the right lower part of the brackets 7 at the two ends by a rotating shaft 9. At this point the broom has been retracted up against the side of the cross brace 2.

In fig. 2, the shovel block and the broom are both folded upwards at two sides of the cross bracket, which is also a state diagram when water is sprayed. The retracted state of the broom remains the same as in fig. 1. The user pulls the dolly up clockwise in fig. 1. At this point the shovel is rotated clockwise from the position of fig. 1 to the position of fig. 2 where the shovel stands up against the left side of the cross brace 2 and stops under the spring force of the spring it is mounted on. The shovel block and the broom are provided with springs on rotating shafts, so that the shovel block and the broom can rotate upwards to abut against two sides of the transverse support respectively in a free state, namely without the action of external force. The rotating card 13 is fixed on the rotating shaft 9, and the rotating card 13 rotates clockwise along with the rotating shaft 9 to the lower left of the two end brackets 7 to stop. When the user releases the catch 14, the catch 14 is immediately rotated counter-clockwise against the abutment 12 by the torsion spring. The dolly is also shown cocked up in fig. 2 to show how the rotating dolly is clear and has not yet rotated down to be caught by the abutment.

In FIG. 3, the shovel is shown in the up position and the broom is shown in the down position. In fig. 3, the lever of fig. 2 is turned in one direction, i.e., the two-end holder 7 facing the paper surface in fig. 1 and 2 is turned to be placed behind in fig. 3, and the inner one of the two-end holders in fig. 1 and 2 is turned to face the paper surface. In this turning position, the broom originally installed on the right side of the two end brackets is changed into the broom of fig. 3 installed on the left side of the two end brackets. The shovel block 11 is folded upwards and leans against the right side of the cross bracket 2. At this time, a rotating card 13 is installed and connected on the end of the rotating shaft 9 installed on the broom shell, and the structure and the direction of the rotating card are the same as those of the shovel block in the figures 1 and 2. The structure and direction of the resisting card 14 which is also arranged on the brackets at the two ends are the same as those in figures 1 and 2. At this time, the front end of the abutting card 14 abuts against the rotating card 13. The right side of the upper end of the broom shell leans against the horizontal bracket 2. The broom is fixed and cannot move left and right. When in use, a user holds the left side of the handle and uses the broom to sweep sundries such as garbage, stones and the like forwards on the ground. When the broom is completely swept, the broom is retracted upwards in the same way as the shovel block in fig. 2.

Fig. 4 is a view showing a spring mounted on the rotating shaft above the shovel. The spring is a torsion spring, i.e. the spring wire 17 is wound on the rotating shaft for a set number of turns clockwise from the middle left of the rotating shaft 9 as shown in fig. 4. The spring wires 17 are actually coiled and abutted together, and are drawn in sparse turns for viewing in fig. 4. The spring wire section protruding to the left in fig. 4 is pressed into a notch 16 in the back of the shovel. The section of spring steel wire on the right in fig. 4 abuts against the same notch formed below the transverse bracket, the transverse bracket is positioned right in front of the paper surface, and the transverse bracket is not drawn in order to not shield the graph in fig. 4.

Also, the winding and mounting structure of the torsion spring on the broom is the same as the winding and mounting structure of the torsion spring on the shovel block.

The using method comprises the following steps: when the floor is washed, the shovel block and the broom are rotated upwards and clamped by the abutting clamp. The switch is turned on, and the ground can be washed by holding the handle rod. When the ground attachments are to be shoveled and stones are to be shoveled, the switch is turned off, and the shoveling blocks are put down for operation. After the ground attachments are shoveled and stones are shoveled away, the shoveling blocks are upwards retracted, the switch is turned on, and the land washing is continued. When the garbage on the ground is too much and the water is slowly flushed away, the switch is turned off, and the broom is put down and clamped by the resisting clamp. When the garbage and the stones on the ground are swept, the broom is folded upwards, the switch is turned on, and the ground is continuously washed.

Except the technical features described in the specification, the other technical features are the prior art.
