Technical Field

The utility model relates to a transmission technology field especially relates to an unloader specifically is an extension type unloader.

Background

At present, along with the continuous improvement of production and processing automation, more and more conveying devices are applied to various industries, wherein a conveying belt is a conveying device which is generally applied, the conveying belt is generally used due to the fact that the conveying belt can quickly convey materials, but the general conveying belt is continuously conveyed, if the conveying belt is used for batch quantitative discharging, the problem cannot be effectively solved, and a discharging device capable of batch quantitative discharging on the conveying belt is needed at present.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the problem that above-mentioned prior art exists, provide an extension type unloader, solve present conveyer belt device can not the quantitative problem of ejection of compact in batches.

The utility model provides a technical scheme that its technical problem adopted: the extension type blanking device comprises a rack, wherein a conveying belt for transmission is arranged at the top of the rack, a moving frame which reciprocates below the blanking end of the conveying belt is connected onto the rack, a tipping bucket for receiving materials is rotatably connected onto the moving frame, a baffle plate which is horizontally arranged below the tipping bucket is fixed onto the moving frame, the gravity center of the tipping bucket is positioned at the rear side of the rotary joint, a pull rope is connected onto the rack, and the other end of the pull rope is fixed onto the front end face of the tipping bucket so that the other end of the pull rope axially stretches along the moving direction of the moving frame during stretching. After setting up like this, the tipping bucket relies on the travelling gantry to receive the material in conveyer belt unloading end below, then the travelling gantry takes the tipping bucket to move toward the outside, the stay cord will be flare-out gradually in the removal process, until taking the rotation to empty the material with the tipping bucket, the completion is emptyd the back travelling gantry and is moved backward, the stay cord relaxs the tipping bucket and is reseed like the back side rotation under the gravity center effect, lean on the baffle at last, whole tipping bucket operating condition all is according to the mobile position automatic operation, do not need extra structure, the structure is simplified low cost, it is effectual. Compare in the conveyer belt and do not stop the ejection of compact all the time, this kind of structure of tipping bucket can the automatic timing ejection of compact, avoids the short time excessively to pile up, is fit for batch quantitative transmission.

As a further improvement of the utility model, the tip face before the tipping bucket forms the gliding part that supplies the material landing from up gradually to the outside slope down. The tipping bucket is rotatory to empty the unloading with the material, and this in-process will guarantee that the material breaks away from the tipping bucket and need rotate great angle, has great requirement to the tipping bucket reset structure, and the gliding portion of tipping bucket front end is because it is inclined itself, and the tipping bucket only needs to rotate less angle and just satisfies the purpose of pouring the material, not only alleviates the reset structure requirement, can also effectively accelerate and empty speed, improves transmission efficiency.

As a further improvement, the tipping bucket is of a strip-shaped groove structure, the left side and the right side of the tipping bucket are rotatably connected on the movable frame, and the rotating connection part of the tipping bucket is positioned at the front side of the central axis thereof to form a gravity center leaning structure. After the arrangement, the tipping bucket does not need to change the structure of the tipping bucket to move the gravity center, and the gravity center is moved backwards by means of the preposed turning of the rotary connecting position, so that the tipping bucket has the capability of resetting by means of the gravity center in the rotary structure, and the tipping bucket is simple in structure and practical.

As a further improvement of the utility model, the front half part of the baffle coincides with the upper and lower parts of the rear half part of the bottom surface of the tipping bucket, and the rear half part of the bottom surface of the tipping bucket leans against the baffle. The tipping bucket needs to rotate by a preset angle to carry out blanking, in order to avoid the collision caused by the interference of the front half part of the bottom surface of the tipping bucket and the baffle in the rotating process, the baffle and the rear half part of the tipping bucket are overlapped to avoid the collision in the rotating process, the tipping bucket can lean on the baffle, and further, in order to avoid the excessive rotation of the tipping bucket and the failure of resetting, the baffle can rotate the tipping bucket in the preset angle, the excessive rotation is avoided, a good limiting protection effect is played, and the normal operation of the rotation of the tipping bucket is ensured.

As the utility model discloses a further improvement, the left and right sides of frame is rotated and is connected with the gear, removes frame left and right sides bottom respectively with gear engagement, removes frame left and right sides tail end and frame sliding connection. Sliding connection between removal frame and the frame and cooperation gear meshing mode carry out the transmission, and gear meshing enables more smooth nature when reciprocating sliding, makes the tipping bucket remove more stably.

As a further improvement, the frame is provided with a cylinder, and the front end of the cylinder push rod is connected to the bottom of the baffle plate. The cylinder is connected with the baffle and used for driving the moving frame to move in a reciprocating mode.

The utility model discloses profitable effect is: the utility model discloses a rational in infrastructure, compact drives tipping bucket reciprocating motion through removing the frame and comes automatic unloading, utilizes the stay cord to make the rotatory unloading of tipping bucket at the reciprocating motion in-process, makes the tipping bucket rotate backward and reset utilizing the focus, and whole structure is retrencied, can effectively accomplish quantitative unloading in turn, excellent in use effect is suitable for the popularization.
