Description

Technical Field

[0001] The utility model relates to the field of concrete material transportation, in particular to a concrete mixer truck with a splash-proof device. Background Art

[0002] A concrete truck, also known as a concrete mixer truck, is a special truck used to transport and mix construction concrete.

[0003] In the application document with the Chinese patent publication number CN201645662U, a splash-proof device for the discharge hopper of a cement concrete mixing device is disclosed, which includes a sleeve body sleeved outside the discharge port of the discharge hopper, the inner diameter of the lower opening of the sleeve body is smaller than that of the upper opening; a power unit for driving the sleeve body to move up and down along the discharge port of the discharge hopper; a connection and support unit for connecting the sleeve body and the power unit and supporting the sleeve body. In this application document, the sleeve body is driven by the power unit to move up and down along the discharge port of the discharge hopper. When the vehicle body receives the material, the sleeve body can cover the material receiving port of the vehicle body to avoid the splash of concrete, avoid the waste of concrete, keep the appearance of the mixing device and the floor clean, and reduce unnecessary cleaning work.

[0004] However, when discharging the concrete mixer truck with a splash-proof device, the concrete material is directly poured onto the ground through the discharge hopper. Due to the relatively high distance between the discharge hopper and the ground, the sleeve body cannot cover the lower end of the discharge hopper and guide the concrete discharge. Part of the concrete will leak from the disconnection between the discharge hopper and the sleeve body, and the concrete will impact the ground under the influence of the height difference, which is likely to cause the concrete to splash. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art that when discharging the concrete mixer truck with a splash-proof device, the concrete is prone to leakage and splash, and to provide a concrete mixer truck with a splash-proof device.

[0006] The utility model provides a concrete mixer truck with a splash-proof device, which includes a vehicle body, and the vehicle body is provided with a material guiding mechanism and a mixing drum;

[0007] The material guiding mechanism includes a support plate, a discharge hopper and a splash-proof mechanism. The support plate is connected to the vehicle body, the discharge hopper is connected to the support plate, the splash-proof mechanism is connected to the support plate, the splash-proof mechanism is communicated with the discharge hopper, the discharge hopper is located below the discharge port of the mixing drum, the splash-proof mechanism is located below the discharge hopper, and the discharge hopper is arranged at an interval from the mixing drum.

[0008] A concrete mixer truck with a splash-proof device according to the present utility model collects concrete through a discharge hopper arranged below the discharge opening of the mixing drum. The discharge hopper increases the collection area of the concrete and avoids concrete leakage. The concrete enters the splash-proof mechanism through the discharge hopper, and the splash-proof mechanism can block and divert the flowing concrete to prevent splashing during the concrete discharging process. By arranging the discharge hopper at an interval from the mixing drum, the interference of the discharge hopper with the rotation of the mixing drum is avoided. Thus, leakage and splashing of the concrete during the discharging process are prevented.

[0009] Preferably, the discharge hopper is a funnel-shaped structural member. The discharge hopper is provided with a discharge pipe, the discharge pipe penetrates through the support plate, the discharge pipe is communicated with the discharge hopper, and the discharge hopper is located below the discharge opening.

[0010] The top of the funnel-shaped structural member has a larger opening, which can collect a larger range of concrete, thus avoiding leakage during concrete discharging. By the discharge pipe penetrating through the support plate, the support plate can provide good support for the funnel-shaped structural member.

[0011] Preferably, a plurality of guide plates are arranged inside the discharge pipe, the guide plates are inclined, and the plurality of guide plates are arranged in a staggered manner.

[0012] During the flow of the concrete, the concrete impacts the guide plates, and the guide plates reduce the flow rate of the concrete and the kinetic energy of the flowing concrete, thereby reducing the splashing of the concrete.

[0013] Preferably, the splash-proof mechanism includes a telescopic pipe. The end of the telescopic pipe is communicated with the discharge hopper, and the telescopic pipe is connected to the discharge pipe.

[0014] The length of the telescopic pipe can be adjusted according to the discharging height, improving the applicability.

[0015] Preferably, the telescopic pipe includes a first end section, a last end section and a plurality of intermediate sections. The first end section is nested and connected with the intermediate sections, adjacent intermediate sections are nested and connected, and the last end section is nested and connected with the intermediate sections; the first end section is connected to the discharge pipe.

[0016] When the telescopic pipe is shortened, the first end section, the last end section and the plurality of intermediate sections can be stacked, thereby reducing the occupied space; the last end section is located at one end away from the discharge pipe.

[0017] Preferably, the head segment is slidably connected to the intermediate segment, adjacent intermediate segments are slidably connected, the tail segment is slidably connected to the intermediate segment, and the head segment is slidably connected to the discharge pipe; limiting portions are respectively provided on the head segment, the tail segment and the intermediate segment; the head segment and the intermediate segment can be abutted through the limiting portion, adjacent intermediate segments can be abutted through the limiting portion, the tail segment and the intermediate segment can be abutted through the limiting portion, and the head segment and the discharge pipe can be abutted through the limiting portion; the support plate is provided with a telescopic mechanism, the telescopic mechanism is connected to the tail segment, and a pushing member is provided on the tail segment.

[0018] The limiting portion can prevent disconnection between adjacent segments and prevent disconnection between the head segment and the discharge pipe; the telescopic mechanism provides the driving force for the telescopic movement so that the length of the telescopic pipe can be controlled; when the telescopic pipe is stacked and stored, the pushing member abuts against the bottom of the tail segment to push the tail segment for storage.

[0019] Preferably, the telescopic mechanisms are respectively provided on both sides of the tail segment.

[0020] By respectively arranging the telescopic mechanisms on both sides of the tail segment and making the telescopic mechanisms move synchronously, the telescopic pipe can move smoothly.

[0021] Preferably, a splash-proof cone and a support rod are arranged in the tail segment, the splash-proof cone is connected to the support rod, and both ends of the support rod are respectively connected to the tail segment.

[0022] The support rod is used to support the splash-proof cone, and the pointed part of the splash-proof cone is located on the top side. When the concrete impacts the splash-proof cone, the flow direction is changed, thereby avoiding the splashing of the concrete.

[0023] Preferably, the head segment, the tail segment and the several intermediate segments are all pipe segments with a "mouth"-shaped cross section.

[0024] The pipe segment with a "mouth"-shaped cross section can prevent rotation between segments and is convenient for improving the length control accuracy of the telescopic pipe.

[0025] Preferably, a flexible member for abutting against the ground is provided at the bottom of the splash-proof mechanism.

[0026] The flexible member can abut against the ground to seal the gap between the ground and the splash-proof mechanism and avoid the splashing of the concrete.

[0027] Compared with the prior art, the beneficial effects of the present utility model are:

The telescopic pipe is slidably connected to the discharge pipe 24; The telescopic pipe includes a head section, a tail section and a plurality of intermediate sections. The head section is nested with the intermediate sections. Adjacent intermediate sections are nested with each other. The tail section is nested with the intermediate sections; The head section is connected to the discharge pipe 24.

[0043] Specifically, the head section, the tail section and a plurality of intermediate sections are all pipe sections with a cross-section in the shape of a "mouth". When the telescopic pipe is in the extended state, the head section is located at the top, the tail section is located at the bottom, and the intermediate sections are located between the head section and the tail section.

[0044] Specifically, the limiting part includes a first limiting block 15, a second limiting block 17 and a third limiting block 110. The first splash guard 16 is the head section, the second splash guard 18 is the middle section, and the third splash guard 111 is the end section. A first limiting block 15 is arranged at the upper end of the first splash guard 16. The first limiting member can abut against the discharge hopper 13. The discharge hopper 13 is slidably sleeved on the first splash guard 16. A second limiting block 17 is arranged at the upper end of the second splash guard 18. The first splash guard 16 is slidably sleeved on the second splash guard 18. A stop block 19 is arranged on the inner side of the second splash guard 18. A third limiting block 110 is arranged at the upper end of the third splash guard 111. The second splash guard 18 is slidably sleeved on the third splash guard 111. A pushing member 113 is arranged on the inner side of the lower end of the third splash guard 111.

When the sections are stacked, the pushing member 113 pushes the second splash guard 18, and the stop block 19 on the second splash guard 18 pushes the first splash guard 16, so that the first splash guard 16, the second splash guard 18 and the third splash guard 111 are stacked. The third splash guard 111 is the end section. When the third splash guard 111 rises, the pushing member 113 and the stop block 19 can respectively lift and support the second splash guard 18 and the first splash guard 16, so as to effectively drive the second splash guard 18 and the first splash guard 16 to rise upward.

[0045] In one or several embodiments, a flexible member 112 for abutting against the ground is arranged at the bottom of the splash prevention mechanism 100. Specifically, the flexible member 112 is a plastic film adhered to the lower end of the third splash guard 111.

[0046] Specifically, by starting the telescopic mechanism 116 to drive the third splash guard 111, the second splash guard 18 and the first splash guard 16 to move vertically, so as to adjust the flexible member 112 to closely adhere to the ground, thereby preventing the concrete from splashing out after falling to the ground. Fixed blocks 117 are symmetrically arranged on the outer side of the third splash guard 111, and the fixed blocks 117 are connected to the end of the telescopic mechanism 116.

[0047] In one or more embodiments, a splash cone 115 and a support rod 114 are provided inside the third splash guard 111 serving as an end segment.

First, the cylinder barrel with the largest diameter starts to extend with the lowest hydraulic pressure. When the stroke end point is reached, the cylinder barrel with a slightly smaller diameter starts to extend, and the last-stage with the smallest diameter extends finally; as the number of working stages increases, the diameter of the extending cylinder barrel becomes smaller and smaller, and the working speed becomes faster; the telescopic mechanism 116 is a hydraulic push rod, and the hydraulic push rod is connected to a hydraulic pump for control; in some embodiments, one end of the pushing member 113 is connected to the support rod 114.

[0048] In one or more embodiments, a number of guide plates 14 are provided inside the discharge pipe 24, and the several guide plates 14 are arranged in a staggered manner. When the mixing drum 2 discharges materials, the concrete raw materials fall into the inside of the discharge hopper 13 and slide downward through the guide plates 14 and drop onto the splash cone 115, which can reduce the impact force of the concrete hitting the ground and narrow the splashing range of the concrete falling to the ground.

[0049] The working principle of this embodiment: When the mixing drum 2 discharges materials, the concrete raw materials fall into the inside of the discharge hopper 13 and slide downward through the guide plates 14 and drop onto the splash cone 115, which can reduce the impact force of the concrete hitting the ground and narrow the splashing range of the concrete falling to the ground. By starting the telescopic mechanism 116 to drive the third splash guard 111, the second splash guard 18 and the first splash guard 16 to move longitudinally, so as to adjust the flexible member 112 to closely adhere to the ground. The third splash guard 111, the second splash guard 18, the first splash guard 16 and the flexible member 112 can expand the longitudinal movement range and generate a shield, thereby preventing the concrete from splashing outward after falling to the ground. When the third splash guard 111 rises, the pushing member 113 and the stop block 19 can respectively lift and support the second splash guard 18 and the first splash guard 16, thereby effectively driving the second splash guard 18 and the first splash guard 16 to rise upward. The designs of the first limit block 15, the second limit block 17 and the third limit block 110 can limit the falling range of the first splash guard 16, the second splash guard 18 and the third splash guard 111, and prevent the first splash guard 16 and the second splash guard 18 from falling off.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
