However, the patent still has certain shortcomings in actual use. Since the patent drives various structures to move through layers of gear transmission and thread cooperation, the planar movement of the rainproof plate is achieved during the transmission process. In order to achieve this effect, many mechanical transmission structures are used, and mechanical transmission methods such as gear meshing need to be regularly adjusted and maintained in a unified manner. The overall workload is large, and the actual cost of use is also high, which is not conducive to widespread promotion and use.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a rainproof structure for a feed hopper of a concrete mixer truck, comprising a feed hopper main body 1, a rain shield 2 abutting against the top of the feed hopper main body 1, a scraper block 3 connected to the inner right wall of the feed hopper main body 1 by screws, a linear moving mechanism 400 for driving the rain shield 2 to move is installed on the outer side of the feed hopper main body 1, and a peripheral component 500 for cooperating with the linear moving mechanism 400 is installed on the outer side of the feed hopper main body 1; through the coordinated use of the rain shield 2 on the top of the feed hopper main body 1 and the linear moving mechanism 400 and the peripheral component 500 on the outer side, the planar movement of the rainproof structure can be achieved through a simple structure, thereby greatly reducing the number of required mechanical transmission structures, reducing the workload and operating difficulty of inspection and maintenance work, improving the convenience of actual use, and also reducing the cost of use, which is conducive to wide promotion and use, thereby effectively improving the practicality of the rainproof structure of the feed hopper of a concrete mixer truck.

[0025] In this embodiment, the linear motion mechanism 400 is a structure for driving the rain shield 2 to move smoothly in a linear manner.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the linear moving mechanism 400 includes a support plate 401 fixed to the right side of the feed hopper body 1, an electric push rod 402 fixedly installed on the top of the support plate 401, a connecting plate 403 fixed to the output shaft of the electric push rod 402, a connecting rod 404 fixed to the left side of the connecting plate 403, four fixed blocks 405 respectively fixed to the front and back sides of the feed hopper body 1, a support block 406 fixed to the top of the fixed block 405, a positioning box 407 fixed between the tops of two corresponding support blocks 406, a positioning rod 408 fixed to the inner side of the positioning box 407, and two positioning blocks 409 fixed to the outer side of the rain shield 2.

[0027] It should be noted that the cross-section of the scraper block 3 is triangular, and the top of the scraper block 3 fits with the bottom of the rain shield 2, so that the rain shield 2 can slide relative to the scraper block 3 when translated, so that the concrete at the bottom of the rain shield 2 can be shoveled off by the scraper block 3, and the left end of the connecting rod 404 is fixedly connected to the right side of the rain shield 2, so that the connecting rod 404 can drive the rain shield 2 to move.

[0028] In addition, the two positioning boxes 407 are opened on opposite sides, and the two positioning boxes 407 are respectively located on the front and back sides of the rain shield 2. The left side of the positioning block 409 is provided with a through hole for the corresponding positioning rod 408 to slide. The positioning block 409 is located inside the corresponding positioning box 407, so that the rain shield 2 can achieve stable left and right translation movement under the sliding cooperation between the two positioning blocks 409 and the two positioning rods 408.

[0029] In this embodiment, the peripheral component 500 is an auxiliary structure used in conjunction with the linear motion mechanism 400 .

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the peripheral component 500 includes a support rod 501 fixed between the right side of the feed hopper body 1 and the bottom of the support plate 401, a rainproof frame 502 fixed to the outside of the support plate 401 and located on the outside of the electric push rod 402, and a rain sensor 503 fixedly installed on the top of the front positioning box 407.

[0031] It should be noted that the support rod 501 is arranged at an angle, so that the support rod 501 can provide good auxiliary support for the support plate 401, and the left and right sides and the bottom of the rainproof frame 502 are opened. The left side of the rainproof frame 502 is fixedly connected to the right side of the feed hopper body 1, so that the rainproof frame 502 can provide a certain rainproof function for the electric push rod 402, and will not hinder the normal operation of the electric push rod 402. The outer side of the rainproof frame 502 is arc-shaped, so that rainwater on the outside can slide off.

[0032] In addition, the top of the rain shield 2 is arc-shaped, and the length and width of the rain shield 2 are respectively greater than the length and width of the feed hopper body 1, so that the rain shield 2 can play a good rain-shielding role on the top of the feed hopper body 1, and at the same time, it is easy for rain to slide down in the arc state. The rain sensor 503 detects rain by using the capacitance formed by rainfall to cause the capacitance value of the capacitor to change. When raindrops touch the sensor surface, tiny electrical signals are generated. The sensor senses the presence and intensity of rain by detecting the changes in these electrical signals. The rain sensor 503 is connected to the on-board control host of the concrete transport truck so that the operator can check the status of the rain sensor 503 in the main driving seat. At the same time, the signal of the rain sensor 503 can also be transmitted to the on-board control host.

[0033] The working principle of the above embodiment is:

[0034] On rainy days, the electric push rod 402 is started to drive the connecting plate 403 to move, so that the connecting rod 404 moves synchronously, so that the rain shield 2 can be driven to move in a straight line. At the same time, under the cooperation between the positioning block 409 and the corresponding positioning rod 408, the rain shield 2 can move smoothly. When the rain shield 2 moves to the top of the feed hopper body 1, it can protect the feed hopper body 1 from rain. When it needs to be opened, according to the above principle, the electric push rod 402 is started to drive the connecting plate 403 and the connecting rod 404 to move, so that the rain shield 2 is away from the top of the feed hopper body 1. The scraper block 3 will scrape the bottom of the rain shield 2 during the movement, so that the concrete stuck to the bottom of the rain shield 2 can be scraped off, so that the interior of the feed hopper body 1 can be connected with the outside world, and the concrete can be poured through the top of the feed hopper body 1. At the same time, on rainy days, when the rain shield 2 is forgotten to be closed, the rain sensor 503 will transmit a signal after being wetted by rain, thereby controlling the electric push rod 402 to start. According to the above principle, the rain shield 2 is moved to the top of the feed hopper body 1 to block the rain, and the effect of translational rain blocking can be achieved through simple structural coordination.

[0035] Compared with the prior art, the rainproof structure of the feed hopper of the concrete mixer truck can realize the planar movement of the rainproof structure through a simple structure through the cooperation between the rain shield 2 on the top of the feed hopper body 1 and the outer linear moving mechanism 400 and the peripheral component 500, thereby greatly reducing the number of required mechanical transmission structures, reducing the workload and operating difficulty of the inspection and maintenance work, improving the convenience of actual use, and also reducing the cost of use, which is conducive to wide promotion and use, thereby effectively improving the practicality of the rainproof structure of the feed hopper of the concrete mixer truck, and solving the problem that the rainproof device of the feed hopper of the existing concrete mixer truck requires more structures and more complicated mechanical transmission to achieve planar movement.

[0036] The electrical components appearing in the article are all electrically connected to the main controller of the concrete transport truck and the on-board power supply. The provision of power supply is common knowledge in the field. The main controller of the concrete transport truck can be a conventional known device that plays a control role such as a control mainboard and a control host. It can be realized through simple programming by technicians in this field, and they are all existing publicly available power connection technologies and will not be described in detail in the article.

[0037] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
