Further, actuating mechanism is including carousel, reel, rocker and second wire rope, and the rotary type is connected with the carousel in the middle of the riser right flank, and carousel leading flank centre of a circle position rigid coupling has the reel, and around there being second wire rope on the reel, the second wire rope tail end and the outer right flank sub-unit connection of framework, and the even spaced division in carousel lateral surface circumference has the draw-in groove, draw-in groove and the cooperation of kelly, and carousel trailing flank eccentric position rigid coupling has the rocker.

Further, still including chucking device, chucking device is including horizontal slider, the second spring, big wedge, the pull rod, little wedge and third spring, open riser left side lower part has the guide slot, open guide slot top left side has horizontal spout, be equipped with in the horizontal spout rather than complex horizontal slider, sliding fit in horizontal slider and the horizontal spout, be connected with the second spring between horizontal slider left surface and the horizontal spout left side, horizontal slider bottom rigid coupling has big wedge, big wedge is located the guide slot, open riser bottom left side has the guide hole, the guide hole communicates in with the guide slot, be equipped with the pull rod in the guide hole, pull rod top rigid coupling has little wedge, little wedge is located big wedge right side rather than the contact, be connected with the third spring between little wedge bottom and the guide slot bottom, the third spring housing is on the pull rod.

Further, the guide plate further comprises a guide rod, a fourth spring and a contact plate, wherein three grooves are formed in the top of the 7-shaped plate at intervals, the guide rod is arranged in each groove, the fourth spring is connected between the top end of the guide rod and the top of each groove, and the contact plate is fixedly connected between the bottom ends of the three guide rods.

Further, the steel wire rope swinging device further comprises a buffer sleeve, a rubber pad and a fifth spring, wherein the buffer sleeve is arranged at the left part of the first steel wire rope, the rubber pad is fixedly connected to the right side surface of the buffer sleeve, the fifth spring is connected between the left side surface of the buffer sleeve and the right side surface of the left swinging plate, and the fifth spring is sleeved on the first steel wire rope.

Firstly, an operator places the device on a window, makes a 7-shaped plate contact with the window, then hangs a second hook on a garbage truck, starts the garbage truck to move to the left to drive the second hook to move to the left, the second hook moves to the left to drive a left swinging plate to move to the left, the left swinging plate moves to the left to straighten a first steel wire rope, stops starting the garbage truck, and the operator can pour the construction waste into a frame body. When a proper amount of construction waste is in the frame body, the clamping rod can be pulled to move downwards, the first spring is compressed, the clamping rod moves downwards and is not in contact with the driving mechanism, an operator can move the frame body downwards through the driving mechanism, the frame body moves downwards to the lowest end, the driving mechanism stops operating, the first hook is pulled to be separated from the hanging ring, the stay wire is loosened, the arc-shaped cover plate swings downwards to not block the construction waste, and the construction waste falls into the garbage truck. When rubbish in the frame is whole to drop, operating personnel can stimulate first couple rebound and hang on the link, and then first couple drives arc apron upswing through acting as go-between and resumes to the normal position, and rethread actuating mechanism drives the frame rebound and resumes to the normal position, loosens the kelly, and because of the effect of first spring, kelly rebound is fixed with actuating mechanism, and operating personnel can pour building rubbish into the frame once more, presses the operation, can pour building rubbish into the garbage truck once more. When the construction waste is completely poured into the garbage truck, the second hook can be separated from the garbage truck, and then the device can be taken down from the window.

When having suitable amount building rubbish in the framework, operating personnel pulling kelly moves down and breaks away from in the draw-in groove, wave the rocker reversal again, the rocker reversal drives the carousel reversal, the carousel reversal drives the reel reversal, the reel reversal loosens second wire rope, and then the framework moves down and drives building rubbish downstream to garbage truck top, pulls again first couple and link and breaks away from, and the arc apron is opened, and building rubbish falls out from the framework. In the same way, after the whole droppings of building rubbish in the framework, and first couple is hung on the link, can wave rocker corotation, rocker corotation drives the carousel corotation, and then drives reel corotation and convolute the second wire rope, and the second wire rope is convoluteed and is driven the framework rebound and resume to the normal position, stops to wave the rocker, loosen the kelly, because of the effect of first spring, kelly rebound inserts in the draw-in groove, kelly and draw-in groove fit in with the carousel fixed, and then fixed the framework.

At the beginning, the second spring is the compression state, at first operating personnel pulling pull rod downstream, the pull rod downstream drives little wedge and moves down, the compression of third spring, because of the effect of second spring, little wedge downstream makes big wedge remove right, big wedge moves right when moving completely to the guide slot, stop pulling the pull rod, can place this device on the window, 7 templates and window contact, loosen the pull rod again, because of the effect of third spring, the pull rod moves upward and drives little wedge and move upward, little wedge moves upward and promotes big wedge and move left, the compression of second spring, big wedge moves left and contacts with the window, and then big wedge fixes 7 templates on the window. After the device is used up, an operator can pull the pull rod to move downwards again, so that the large wedge block moves rightwards and is not in contact with the window, the device is taken down, and the pull rod is loosened to enable the large wedge block to move leftwards and return to the original position. Therefore, the 7-shaped plate can be prevented from being separated from the window to influence the transportation of the construction waste.

When 7 templates are fixed on the window, the contact plate contacts with the window, and then the framework is when transporting building rubbish, because of the effect of fourth spring, the contact plate can prevent 7 templates from crushing the window.

When the frame body drives the construction waste to move downwards to the lowest part, the frame body is in contact with the rubber pad, and the buffer sleeve buffers the downward force of the frame body under the action of the fifth spring. Therefore, the construction waste can be prevented from falling out due to the excessive downward moving force of the frame body.

The invention has the following advantages: according to the garbage truck, garbage is poured into the frame body, the frame body can be moved downwards to the position above the garbage truck through the driving mechanism, the first hook is pulled to be separated from the hanging ring, the arc-shaped cover plate is opened, building garbage is poured into the garbage truck, people do not need to move the garbage for treatment, time and labor are saved, the working efficiency is higher, the 7-shaped plate can be prevented from being separated from the window to influence the transportation of the garbage through the clamping device, and the frame body can be buffered downwards through the buffer sleeve to avoid the falling of the building garbage.
