Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete mixer trucks, specifically to a filter material chute for concrete mixer trucks. Background Technology
[0002] With the development of the engineering and construction industry, the country is increasingly strict in its control over quality and environmental protection requirements. As a result, construction sites are paying more attention to the quality inspection of concrete delivery. The quality of concrete depends on the selection and proportion of materials. Among them, the selection of sand and gravel particles has a significant impact on the strength of different grades of concrete. The particle size of sand and gravel plays a crucial role in the final strength of concrete in different scenarios. Due to issues such as the processing technology of concrete companies, the mixing and transporting trucks may output some concrete with larger sand and gravel particle sizes. Receiving non-compliant concrete is an unnecessary loss for the construction party. It also requires a certain amount of screening, which is quite troublesome and slows down the construction progress.
[0003] Meanwhile, the government attaches great importance to the environmental problems caused by concrete spillage during transportation and has implemented strict enforcement through the installation of high-definition surveillance cameras on roads. A device for detecting concrete particle size and a device for controlling spillage have become essential requirements. Utility Model Content
[0004] The purpose of this invention is to provide a filter material chute for concrete mixer trucks. The chute is equipped with a filter material mechanism and a material blocking mechanism to directly output concrete with sand and gravel particle size that meets the standards, while also solving the problem of material spillage.
[0005] The technical solution adopted by this utility model is: a filter material chute for a concrete mixer truck, including a chute, a filter material mechanism set in the middle of the chute, and a material blocking mechanism set at the discharge end of the chute;
[0006] The filter media mechanism includes lugs positioned on opposite sides of the top of the chute. A main rod I is rotatably mounted inside the lugs. Multiple filter teeth are fixed on the main rod I, and there are equidistant filter slits between adjacent filter teeth.
[0007] The filter teeth have an open or closed state that can be switched between each other. In the open state, the filter teeth can be flipped to the outside of the chute along with the main body rod I; in the closed state, the end of the filter teeth away from the main body rod I can be flipped to abut against the bottom of the chute along with the main body rod I.
[0008] The depth of the chute gradually narrows from the feed end to the discharge end to prevent the filter teeth in the closed state from flipping towards the discharge end of the chute.
[0009] As a preferred option, the cross-section of the chute is semi-circular.
[0010] As a preferred embodiment, a handle is provided at the end of the main rod I.
[0011] As a preferred option, the filter teeth are straight rods, and the length of the filter teeth is adapted to the depth of the chute at their location.
[0012] As a preferred embodiment, the material blocking mechanism includes lugs positioned on both sides of the top of the chute, a main rod II rotatably mounted inside the lugs, and a material blocking plate fixed on the main rod II, the shape of which is adapted to the cross-sectional shape of the chute at the location of the main rod II.
[0013] As a preferred embodiment, the edge of the baffle plate is provided with a sealing structure that can abut against the bottom of the chute.
[0014] As a preferred option, the sealing structure includes a rubber sheet and a pressure ring;
[0015] The pressure ring is fixed to the baffle plate by bolts, and the rubber is fixed between the pressure ring and the baffle plate.
[0016] As a preferred option, the lugs and the chute are detachably connected.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] The concrete mixer truck filter chute of this application, through the design of equally spaced filter teeth, serves to filter out substandard stones. This device allows for quick and clear detection on the construction site to determine whether the particle size of the sand and gravel meets the requirements, and substandard concrete can be rejected. For concrete transportation companies, this also serves as proof of compliant products. At the same time, to solve the problem of spillage, a material blocking device is designed to effectively prevent concrete in the chute from spilling onto the ground, and the rubber seal acts as a seal to prevent thinner concrete from flowing out.

[0023] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.
[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising" or "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.
[0025] To more clearly describe the specific structural composition of the filter chute for the concrete mixer truck, in conjunction with the attached... Figure 1-2 This embodiment is described as follows:
[0026] like Figure 1 and Figure 2 As shown, a filter material chute for a concrete mixer truck includes a chute 1, a filter material mechanism disposed in the middle of the chute 1, and a material blocking mechanism disposed at the discharge end of the chute 1.
[0027] The filter media mechanism includes lugs 2 positioned on opposite sides of the top of the chute 1. A main rod I3 is rotatably mounted inside the lugs 2. Multiple filter teeth 5 are fixed on the main rod I3, and there are equidistant filter slits between adjacent filter teeth 5. The filter teeth 5 have an open state or a closed state that can be switched between each other. In the open state, the filter teeth 5 can be flipped to the outside of the chute 1 along with the main rod I3. In the closed state, the end of the filter teeth 5 away from the main rod I3 can be flipped to abut against the bottom of the chute 1 along with the main rod I3. The depth of the chute 1 gradually narrows from the feed end to the discharge end to restrict the filter teeth 5 in the closed state from flipping toward the discharge end of the chute 1.
[0028] The filter tooth 5 is a straight rod, and its length is adapted to the depth of the chute 1 at its location. When the cross-section of the chute 1 is semi-circular, the filter tooth 5 in the middle part is longer and the filter tooth 5 at both ends is shorter in the axial direction of the main rod I3. Since the discharge end of the chute 1 is shallow, when the end of the filter tooth 5 away from the main rod I3 flips toward the discharge end of the chute 1, this end will be blocked by the bottom of the chute 1, which can prevent the filter tooth 5 from being pushed away during the process of the concrete moving from the feed end to the discharge end. When it is necessary to switch the filter tooth 5 to the open state, rotate the handle at the end of the main rod I3, and the main rod I3 will drive the filter tooth 5 to flip toward the feed end of the chute 1 until the filter tooth 5 flips to the outside of the chute 1.
[0029] The material blocking mechanism includes lugs positioned on both sides of the top of the chute 1. A main rod II4 is rotatably mounted inside the lugs, and a baffle plate 6 is fixed on the main rod II4. The shape of the baffle plate 6 is adapted to the cross-sectional shape of the chute 1 at the position of the main rod II4. Similarly, since the discharge end of the chute 1 is shallow, the baffle plate 6 cannot be flipped toward the discharge end of the chute 1 when closed, thus avoiding being pushed away by the concrete accumulated in the chute when closed. When it needs to be opened, the main rod II4 drives the baffle plate 6 to flip toward the feed end of the chute 1 until the baffle plate 6 flips to the outside of the chute 1.
[0030] To ensure the sealing between the baffle plate 6 and the bottom of the chute 1 and to prevent the flow of thinner concrete, a sealing structure is provided on the edge of the baffle plate 6 that can abut against the bottom of the chute 1. For example, the sealing structure includes a rubber sheet 7 and a pressure ring 8. The pressure ring 8 is fixed to the baffle plate 6 by bolts, and the rubber sheet 7 is fixed between the pressure ring 8 and the baffle plate 6.
[0031] In this embodiment, two pairs of lugs are provided, which are respectively connected to the two ends of the main body rod I3 and the main body rod II4. The lugs are detachably connected to the chute 1.
[0032] The parts not described in detail in the above embodiments are existing technologies.
[0033] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
