detailed description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully incorporate the concepts of example embodiments. communicated to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

Referring to Fig. 1 to Fig. 7, the utility model discloses a feeding system, which can be used in a wharf, and is suitable for a movable crane with a door seat and a small bridge type grab ship unloader and the like. The feeding system loads the material grabbed by the grab bucket into the dump truck on the dock, so that the dump truck can transport the material to the rear factory area. Referring to FIG. 1 to FIG. 3 , the feeding system of this embodiment includes a hopper 1 and a hopper support beam 2 . The bottom of the hopper 1 is provided with a gate 11 that can be opened and closed. When the gate 11 is closed, the material grabbed by the grab bucket from the ship can be loaded into the hopper 1. Then, after the dump truck drives into the bottom of the hopper 1, the gate 11 When it is opened, the material falls into the bucket of the dump truck from the hopper 1 through the telescopic drop tube 7 .

As shown in Figures 1 to 3, in this embodiment, the side wall of the hopper 1 is surrounded by the front wall 12, the rear wall 13, the left wall 14 and the right wall 15, and the top opening of the hopper 1 Larger, with a smaller opening at the bottom, a windshield 3 is provided on the left, right and rear sides of the top of the hopper 1, and a pedestrian platform 4 is extended on the outside of the windshield 3. Sprinklers are also provided on the right and rear sides. Wherein, the left side of the top of the hopper 1 refers to the area above the left wall 14 , the right side of the top refers to the area above the right wall 15 , and the rear side of the top refers to the area above the rear wall 13 . The upper area of the front wall 12 of the hopper 1 is not provided with a windshield 3 , the grab bucket can move from above the front wall 12 to the upper area of the hopper 1 , and then the materials in the grab bucket fall into the hopper 1 . By setting the windshield wall 3 and the spraying device, it is possible to prevent the flying dust of the material, suppress and eliminate the dust generated during the operation of the feeding system to the greatest extent, and meet the environmental protection requirements. By arranging the pedestrian platform 4, it can be used for maintenance and replacement of wearing parts for spraying devices and the like.

The inclination angle of the front wall 12 of the hopper 1 is smaller than the inclination angle of the rear wall 13, that is to say, the hopper 1 is an asymmetric structure, so when the grab bucket is unloading, the center of the grab bucket is located above the front wall 12 . When the material falls into the hopper 1, it can be buffered by the front wall 12 to prevent the material from arching. When the material falls downward from the hopper 1, it will also be buffered by the front wall 12 to slow down the falling speed and reduce the impact of the material on the dump truck. It can be seen from Fig. 4 that a horizontally arranged blanking grid 6 can also be arranged inside the hopper 1. The blanking grid 6 can discretize the materials, prevent the materials from gathering in the center of the hopper 1, and cause the hopper 1 to block, and can slow down The falling speed of the material can avoid causing dust, and it can also reduce the impact on the dump truck. A wear-resistant liner can be provided inside the hopper 1 to prevent the inner surface of the hopper 1 from being worn by materials and prolong the life of the hopper 1 . The surroundings of the hopper 1 can also be reinforced by angle steel to improve the strength of the hopper 1 .

As can be seen from Figures 1 and 2, the feeding system of this embodiment also includes a hopper support beam 2, which is ring-shaped as a whole, and is sleeved on the outside of the hopper 1, and the hopper support beam 2 passes through the hinge shaft. The type weighing support 21 is connected with the hopper 1, and the hinge type weighing support 21 is made up of a support, an axle sleeve, a shaft pin type sensor, an axle end baffle and the like. The total weight of the hopper 1 and the materials inside the hopper 1 can be measured through the hinged weighing support 21 , so that the net weight of the materials in the hopper 1 can be weighed in real time. When there is too much material in the hopper 1, the grab bucket can stop feeding into the hopper 1. When the feeding system feeds the dump truck, the feeding amount can be controlled to ensure that the dump truck is not overweight, and the total shipment can be counted quantity. The capacity of the hopper 1 can be matched with the loading capacity of the dump truck, and the loading mode of emptying the hopper 1 and filling one car at a time is adopted. This can prevent the remaining material particles in the hopper 1 from being scattered on the track 18 of the gate 11 and cause the gate 11 to fail. Moreover, the size of the hopper 1 can be reduced, the structure of the whole machine is compact, the weight of the equipment is reduced, and the waste of materials and dock space is reduced. .

It can be seen from FIG. 1 and FIG. 2 that at least one vibrating feeder 5 for vibrating the hopper 1 is provided on the hopper 1 . The vibrating feeder 5 can drive the hopper 1 to vibrate, so that the material becomes loose in the hopper 1 and is not easy to block the hopper 1 . In this embodiment, there are two vibrating feeders 5 in total, and they are respectively arranged on the left wall 14 and the right wall 15 .

Referring to FIG. 5 to FIG. 7 , in this embodiment, the gate 11 is in a horizontal state, and a plurality of rollers 17 are arranged on both sides of the gate 11 , and these rollers 17 are rollingly arranged on the track 18 below the hopper 1 . When the gate 11 is opened, materials can fall into the square opening 19 below the hopper 1 . The gate 11 is connected to a horizontally arranged electro-hydraulic push rod 16 and can move horizontally driven by the electro-hydraulic push rod 16 to open or close the hopper 1 .

The feeding system of the utility model directly unloads materials onto dump trucks without the need for ground belt conveyors and material storage warehouses, which greatly reduces site occupation and is suitable for compact loading and unloading docks.

Exemplary embodiments of the present utility model have been specifically shown and described above. It should be understood that the invention is not limited to the disclosed embodiments, but on the contrary, the invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
