Abstract
(B, ) long -pending material device is prevented to pump truck hopper, including the hopper of setting in pump truck chassis front side, the hopper includes the feeding storehouse and carries the feed bin, the feeding storehouse is leaks hopper -shaped, its down port with the transport feed bin is linked together, carry the feed bin to set up the top of chassis and be linked together with the conveyer pipe, the last port in feeding storehouse and the contained angle between the horizontal plane are the acute angle upward install a screen cloth on the port, screen cloth and last port adoption spring elastic connection a vibrating motor is still connected to the upper end of screen cloth, (B, ) during (b) pump sending operation, large bone material and foreign matter in the concrete are blockked the back by the screen cloth, because the inclination of screen cloth and vibrating motor's vibrations, the aggregate that make to exceed the sieve mesh bore and foreign matter are roll and lower along screen cloth edge inclination, can not persist and lead to screen mesh blockage on the screen cloth, and because vibrating motor's vibrations, accelerate the concrete and passed through the speed that the sieve mesh fell into the hopper, the efficiency of the suction of concrete jar during the pump sending is improved. (B, )
Description
Technical field
The utility model belongs to technical field of engineering machinery, especially relates to a kind of pump truck hopper buildup device.
Background technology
Concrete mixer utilizes pressure by the machinery of concrete along pipeline continus convergence, is made up of the pump housing and carrier pipe.In the process of pumping concrete construction; the major diameter aggregate (stone or other foreign matters) exceeding pumping requirements often can be mixed in concrete; enter conveyance conduit for preventing this kind of aggregate and cause plugging phenomenon; need to arrange screen cloth in hopper; screen cloth is arranged on the position lower than hopper about 100mm suitable for reading in hopper usually; but screen cloth intercepts and needs people after after large aggregate and follow the tracks of cleaning; otherwise screen cloth will be caused to block; cause concrete can not flow into hopper inside, thus cause pumping of concrete to inhale the empty plugging caused.
Summary of the invention
The purpose of this utility model, in order to overcome the deficiency of above-mentioned existence, provides a kind of pump truck hopper preventing materials accumulation device.
The technical scheme in the invention for solving the technical problem is: pump truck hopper preventing materials accumulation device, comprise the hopper be arranged on front side of pump truck underframe, described hopper comprises feeding warehouse and conveying feed bin, described feeding warehouse is funnel-form, its lower port is connected with described conveying feed bin, described conveying feed bin arranges the top of underframe and is connected with carrier pipe, angle between the upper port of described feeding warehouse and horizontal plane is acute angle, described upper port is installed a screen cloth, the external diameter of described screen cloth is slightly larger than the external diameter of described upper port, described screen cloth and upper port adopt spring to be connected, a vibrating motor is also connected in the upper end of described screen cloth.
Angle between the upper port of described feeding warehouse and horizontal plane is 30-45 °.
The beneficial effects of the utility model are: during pumpdown, after large aggregate in concrete and foreign matter are stopped by screen cloth, due to the angle of inclination of screen cloth and the vibration of vibrating motor, make to exceed the aggregate of sieve aperture bore and foreign matter along screen periphery angle of inclination tumble and under, can not remain on screen cloth causes screen cloth to block, and due to the vibration of vibrating motor, accelerate concrete falls into hopper speed through sieve aperture, improve the suction efficiency of concrete cylinder during pumping; Described screen cloth is connected with adopting spring between hopper, when avoiding vibrating motor vibration, by conduct vibrations to whole pump truck.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.In figure:
1. underframe, 2. hopper, 21. feeding warehouses, 22. conveying feed bins, 23. upper port, 3. carrier pipe, 4. screen cloth, 5. spring, 6. vibrating motor.
Detailed description of the invention
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1: pump truck hopper preventing materials accumulation device, comprise the hopper 2 be arranged on front side of pump truck underframe 1, described hopper 2 comprises feeding warehouse 21 and conveying feed bin 22, described feeding warehouse 21 is in funnel-form, its lower port is connected with described conveying feed bin 22, described conveying feed bin 22 arranges the top of underframe 1 and is connected with carrier pipe 3, angle between the upper port 23 of described feeding warehouse 21 and horizontal plane is acute angle, described angle is preferably 35 °, described upper port 23 is installed a screen cloth 4, the external diameter of described screen cloth 4 is slightly larger than the external diameter of described upper port 23, described screen cloth 4 and upper port 23 adopt spring 5 elasticity to be connected, a vibrating motor 2 is also connected in the upper end of described screen cloth 4.
During pumpdown, after large aggregate in concrete and foreign matter are stopped by screen cloth 4, due to the angle of inclination of screen cloth 4 and the vibration of vibrating motor 6, make to exceed the aggregate of sieve aperture bore and foreign matter along screen cloth 4 edge tilt angle tumble and under, can not remain on screen cloth 4 and cause sieve pore blockade, and due to the vibration of vibrating motor 6, accelerate concrete falls into hopper 2 speed through sieve aperture, improve the suction efficiency of concrete cylinder during pumping; Described screen cloth 4 is connected with adopting spring 5 elasticity between hopper 2, avoids vibrating motor 6 when vibrating, by conduct vibrations to whole pump truck.
Except technical characteristic described in manual, be those skilled in the art known technology.
