Detailed Description

The self-unloading electric garbage cleaning and transporting vehicle consists of an electric vehicle body 1, a garbage can 2, a bucket hanging mechanism 3 and a lifting mechanism 4; a dustbin 2 is hinged on the electric vehicle body 1; the hinged position of the dustbin 2 and the electric vehicle body 1 is positioned at the upper end or the lower end of the tail end of the electric vehicle body 1 (see the attached figure 1 in the specification); so can rotate around articulated position when 2 atress of dustbin to when making it need empty rubbish, can rotate to the tilt state around articulated position, and then reach the purpose of automatic dumping rubbish.

The dustbin 2 is made of stainless steel material, and the both sides side and the rear end terminal surface of it are equipped with the discharge gate respectively, and discharge gate department all is equipped with the closed door that can open and lock. So people can carry out "unloading" through the discharge gate to the rubbish in dustbin 2, also can throw in the rubbish in the garbage bin of other shapes, perhaps scatter the rubbish and put into dustbin 2 through the discharge gate.

A lifting mechanism 4 (refer to the attached figure 1 in the specification) is arranged on the electric vehicle body 1 at the front end of the dustbin 2; the lifting mechanism 4 can pull the dustbin 2 to rotate around the hinge position.

The lifting mechanism 4 is composed of a lifting motor 5, a lifting steel cable 6, a lifting hanger 7, a driving rotating shaft A8, an upper pulley 9 and a lower pulley 10 (see the attached figures 1 and 2 of the specification).

An upper pulley 9 is fixedly arranged at the upper end of the lifting hanger 7; a lower pulley 10 is fixedly arranged on the dustbin 2 below the upper pulley 9 (see the attached figure 2 in the specification).

One end of the lifting steel cable 6 is fixedly connected with the lifting hanger 7, and the other end of the lifting steel cable 6 is wound on the driving rotating shaft A8 for a plurality of circles and fixedly connected with the driving rotating shaft A8 after sequentially passing around the lower pulley 10 and the upper pulley 9; after the lifting steel cable 6 is wound in this way, when the rotating shaft A8 is driven to rotate in the forward direction, one end of the dustbin 2 can be pulled by the lifting steel cable 6, the upper pulley 9 and the lower pulley 10 to rotate around the hinge position. In the process that the lifting steel cable 6 pulls one end of the dustbin 2, the lower pulley 10 is equivalent to a movable pulley as the lower pulley moves along with one end of the dustbin 2; the shaft of the upper pulley 9 is fixed on the hoisting cradle 7 and thus corresponds to a fixed pulley. Because the lower pulley 10 is equivalent to a movable pulley, the lifting mechanism 4 utilizes the labor-saving principle of the movable pulley, compared with the hydraulic lifting of the dustbin 2 by the existing cleaning and transporting vehicle, the energy consumption is greatly reduced, and the cruising ability of the cleaning and transporting vehicle is prolonged.

In addition, the motor has the characteristic of low noise relative to the hydraulic station, and the hydraulic station does not need to be assembled after the design is adopted, so that the cleaning and transporting vehicle greatly reduces the noise relative to the traditional cleaning and transporting vehicle, and the problem that the noise of the traditional cleaning and transporting vehicle disturbs people is solved to a certain extent.

Thus, when the switch SB1 is closed, the contactor KM1 is electrified, the normally open contact of the contactor KM1 is closed, and the normally closed contact of the contactor KM1 is opened; the positive pole of the battery of the electric vehicle body 1 is connected with the positive pole of the lifting motor 5, and the negative pole of the lifting motor 5 is connected with the negative pole of the battery of the electric vehicle body 1; the lifting motor 5 rotates positively.

When the switch SB2 is closed, the contactor KM2 is electrified, the normally open contact of the contactor KM2 is closed, and the normally closed contact of the contactor KM2 is opened; the positive pole of the battery of the electric vehicle body 1 is connected with the negative pole of the lifting motor 5, and the negative pole of the lifting motor 5 is connected with the positive pole of the battery of the electric vehicle body 1; the lift motor 5 operates in reverse.

The dustbin 2 is provided with a barrel hanging mechanism 3 (see the attached figures 1 and 2 in the specification) at the side surface. When the garbage can is in work, the garbage can hanging mechanism 3 on one side of the garbage can 2 can lift and turn over the garbage can 30 filled with garbage, and the garbage can 2 can be dumped into the garbage can; therefore, when the mounting position of the bucket hanging mechanism 3 is arranged on the same plane with the rear vehicle wheels on one side of the electric vehicle body 1, the stress condition of the bucket hanging mechanism 3 is optimal, and the problem that the garbage truck turns over when the garbage truck 30 is hung on the bucket hanging mechanism 3 is further avoided.

The barrel hanging mechanism 3 is composed of a guide rail 11, a lifting frame 12, a turning frame 13, a barrel locking frame 14, a transmission steel cable 15 and a driving rotating shaft B16 (refer to the attached figures 1, 3, 4, 5 and 6 of the specification).

A guide rail 11 is symmetrically and fixedly arranged on one side surface of the dustbin 2 (see the attached figure 1 in the specification); the section of the guide rail 11 is 7-shaped (see the attached figure 7 in the specification), and the horizontal part of the upper end of the guide rail 11 is positioned above the garbage can 2; the inner side surface of the guide rail 11 is provided with a guide groove 17; the guide groove 17 can guide the lifting frame 12 and the turnover frame 13 to move according to tracks.

A lifting frame 12 is arranged between the guide rails 11; the upper end of the lifting frame 12 is connected with the guide groove 17 of the guide rail 11 in a rolling way through a guide roller A18 (refer to the attached figure 4 in the specification) which is symmetrically arranged.

The upper end of the lifting frame 12 is fixedly provided with a feeding plate 19; the two sides and the lower end of the feeding plate 19 are respectively provided with a guide enclosing plate 20; the feeding opening 21 is arranged on the guiding enclosing plate 20 at the lower end of the feeding plate 19 (see the description and the attached figure 4). The purpose of the feeding plate 19 being so arranged is: when the garbage can is driven by the lifting frame 12 to incline the garbage can 30, garbage in the garbage can 30 can enter the garbage can 2 along the feeding plate 19 through the feeding opening 21, so that the problem of garbage scattering is avoided.

The lifting frame 12 is provided with a barrel locking frame 14 (see the description and the attached drawing 3) in a sliding way through a guide long sliding hole 22; the bucket locking frame 14 can slide up and down inside the lifting frame 12 along the guide long slide hole 22.

A plurality of barrel locking teeth 23 (see the description and the attached figure 5) are welded at the upper end of the barrel locking frame 14; in operation, the locking teeth 23, in cooperation with the feeding plate 19 of the lifting frame 12, can clamp the flanging edge of the trash can 30, thereby driving the trash can 30 to move together.

The lower end of the barrel locking frame 14 is provided with a roll-over frame 13 (see the attached figure 5 in the specification); the upper end of the roll-over stand 13 is hinged with a barrel locking stand 14; the roll-over stand 13 is rotatable about the lock bucket stand 14.

The roll-over stand 13 is movably provided with a limiting rolling sleeve A26, and the roll-over stand 13 below the limiting rolling sleeve A26 is movably provided with a limiting rolling sleeve B27 (refer to the attached figure 6 of the specification). The lower end of the roll-over stand 13 is connected with the guide groove 17 of the guide rail 11 in a rolling manner through guide rollers B24 which are symmetrically arranged. In this way, the lower end of the roll stand 13 will follow the track of the guide groove 17 under the guide of the guide roller B24.

The upper surface of the dustbin 2 is provided with a driving rotating shaft B16 (refer to the attached figures 1 and 7 of the specification) through a driving motor 25. The driving motor 25 can drive the driving rotating shaft B16 to rotate synchronously when working.

One end of the transmission steel cable 15 is fixedly connected with the upper surface of the dustbin 2; the other end of the transmission steel cable 15 passes through the front of the limiting rolling sleeve A26, then passes through the lower part of the limiting rolling sleeve B27, then passes through the front of the limiting rolling sleeve A26, and then is wound on the driving rotating shaft B16 for a plurality of turns and is fixedly connected with the driving rotating shaft B16 (see the attached figure 7 of the specification).

The purpose of thus wire-wrapping the transmission wire rope 15 is: when the garbage can lifting device works, the transmission steel cable 15 acts on the limiting rolling sleeve B27 to pull the turnover frame 13, lock the can frame 14 and the lifting frame 12 to drive the garbage can 30 to move along the guide rail 11; therefore, when the transmission steel cable 15 passes through the front of the limiting rolling sleeve A26 and the transmission steel cable 15 is pulled in a diagonal pulling manner, the transmission steel cable 15 can give a certain horizontal pressure to the roll-over stand 13 close to the dustbin 2 through the limiting rolling sleeve A26, so that firstly, when the roll-over stand 13, the barrel locking stand 14 and the lifting stand 12 move along the vertical section of the guide rail 11, the roll-over stand 13, the barrel locking stand 14 and the lifting stand 12 can tightly abut against the guide rail 11 to keep the roll-over stand to move in a vertical state, and the problem that the roll-over stand 13 turns over at the vertical section of; secondly, when the guide roller a18 of the lifting frame 12 moves to the horizontal section of the guide rail 11, and the lifting frame 12 and the roll-over frame 13 are in a roll-over state (see the attached drawing 10 in the specification), the transmission steel cable 15 enables the roll-over frame 13 to always have the tendency of counterclockwise rotation through horizontal pressure, so that the barrel locking frame 14 and the lifting frame 12 are kept relatively fixed, the garbage can 30 is locked, and the problem that the garbage can 30 is loosened and falls off is avoided.

The driving motor 25 is connected with a battery of the electric vehicle body 1 through a control circuit B; the control circuit B can control the forward and reverse rotation of the drive motor 25. The control circuit B comprises a stroke switch SQ1 and a stroke switch SQ2, the stroke switch SQ1 and the stroke switch SQ2 are located on the end face of the front end of the guide rail 11, the stroke switch SQ1 is located at the upper end of the guide rail 11, and the stroke switch SQ2 is located at the lower end of the guide rail 11; the lifting frame 12 is in intermittent interference connection with a travel switch SQ 2; the roll-over stand 13 is intermittently connected with a stroke switch SQ1 in an interference manner.

When the lifting frame 12 moves downwards to the limit position to be contacted with the stroke switch SQ2 and the turnover frame 13 moves upwards to the limit position to be contacted with the stroke switch SQ1, the driving motor 25 can stop acting; thereby avoiding the danger of continuous movement after the lifting frame 12 and the roll-over stand 13 reach the extreme position.

The control circuit B is a conventional circuit, and all circuits capable of meeting the requirements can meet the use requirements of the cleaning and transporting vehicle. The control circuit B of the cleaning and transporting vehicle consists of a switch SB3, a switch SB4, a contactor KM3, a contactor KM4, a travel switch SQ1 and a travel switch SQ2 (see the attached figure 13 in the specification).

Then the trash can 30 is pushed to enable the flanging edge of the trash can to be positioned above the can locking teeth 23 of the can locking frame 14.

Then the switch SB3 is turned on to drive the driving motor 25 to drive the driving rotating shaft B16 to rotate in the positive direction; during the forward rotation of the driving rotation shaft B16, the driving wire cable 15 is pulled by winding one end of the driving wire cable 15 around the driving rotation shaft B16. In the process of pulling the transmission steel cable 15, the turning frame 13 and the barrel locking frame 14 are pulled to move upwards along the guide long slide hole 22 of the lifting frame 12, when the barrel locking teeth 23 on the barrel locking frame 14 are inserted into the flanging edge of the garbage can 30 and drive the garbage can 30 to move upwards together, when the upper part of the flanging edge of the garbage can 30 is in interference contact with the feeding plate 19 of the lifting frame 12 (see the attached figure 8 of the specification); the roll-over stand 13, the bucket-locking stand 14, the lifting frame 12 and the trash can 30 form a whole, and the transmission cable 15 pulls the whole to move vertically upwards along the vertical section of the guide rail 11.

When the guide roller A18 of the lifting frame 12 enters the curved section of the guide rail 11 during the upward movement of the lifting frame 12 (see the attached figure 9 in the specification), the curved section of the guide rail 11 gives a certain pressure to the guide roller A18, so that the lifting frame 12 rotates upward around the guide roller A18 during the upward movement under the thrust of the roll-over frame 13; when the guide roller a18 of the lifting frame 12 enters the horizontal section of the guide rail 11 and collides with the end of the guide groove 17, the upper end of the lifting frame 12 stops moving, at this time, the transmission cable 15 pulls the roll-over frame 13 to move upwards continuously, the roll-over frame 13 continues to push the lifting frame 12 to rotate upwards around the guide roller a18 during moving upwards, when the roll-over frame 13 moves upwards to the limit position and collides with the stroke switch SQ1, the driving motor 25 stops rotating, at this time, the lifting frame 12 drives the garbage can 30 to be in a downward inclined state (see the attached drawing 10 of the specification), and then the garbage in the garbage can 30 enters the garbage can 2 along the feeding plate 19 under the action of its own gravity.

After the garbage in the garbage can 30 is dumped, the switch SB4 is turned on to drive the driving motor 25 to drive the driving rotating shaft B16 to rotate reversely; in the process of driving the rotating shaft B16 to rotate reversely, one end of the transmission steel cable 15 is slowly released, at this time, the lifting frame 12, the barrel locking frame 14 and the turning frame 13 slowly move downwards along the guide rail 11 under the action of self gravity, when the lifting frame 12 moves downwards to the limit position (namely, the initial position) and is abutted against the stroke switch SQ2, the driving motor 25 stops moving, at this time, the garbage can 30 is placed at the designated position, and the dumping work of the garbage can 30 is completely completed.

Then the garbage collection and transportation vehicle can enter the next cycle, and continuously pours the garbage in the street garbage bin 30 into the garbage can 2; when the garbage can 2 is full of garbage and needs unloading, the cleaning and transporting vehicle is directly driven to an unloading place, and the vehicle is parked after the tail of the vehicle is aligned to a dumping place.

Then the closing door at the tail end of the dustbin 2 is opened, then the switch SB1 is opened, the lifting motor 5 drives the driving rotating shaft A8 to rotate in the forward direction, and in the process of driving the rotating shaft A8 to rotate in the forward direction, one end of the lifting steel cable 6 is wound on the driving rotating shaft A8 to pull the lifting steel cable 6; at this time, the lifting wire rope 6 pulls one end of the dustbin 2 to rotate around the hinge position under the cooperation of the upper pulley 9 and the lower pulley 10, and when the dustbin 2 rotates at a proper inclination angle, the switch SB1 is turned off to stop the lifting motor 5. At this time, the garbage in the garbage can 2 slides down to the unloading position under the action of self gravity, thereby completing the unloading action. After the garbage is dumped, the switch SB2 is opened, the lifting motor 5 drives the driving rotating shaft A8 to rotate reversely, so that the garbage can 2 gradually falls on the electric vehicle body 1, then the switch SB2 is disconnected, and then the cleaning and transporting vehicle can enter the next working cycle.

The self-discharging type electric garbage collection and transportation vehicle has the advantages that the structure is compact, the design is ingenious, garbage of the garbage can 30 can be automatically dumped into the garbage can 2, the problems that noise of the existing garbage collection and transportation vehicle disturbs people, the labor intensity is high, and the working efficiency is low are solved, and the use requirements of people are met.
