DETAILED DESCRIPTION

[0027] 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 of 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.

[0028] The utility model provides Figure 1-Figure 4The environmentally friendly ready-mixed concrete preparation device shown comprises: a preparation box 1, a detachable support column 2 is installed at the bottom of the preparation box 1, a collecting assembly 3 is arranged at the bottom of the preparation box 1, a crushing assembly 5 is arranged inside the preparation box 1, and a hopper 4 is fixed on one side of the preparation box 1; the crushing assembly 5 comprises a first crushing hub 51 and a second crushing hub 52 rotatably installed inside the preparation box 1 and two second motors installed on one side of the preparation box 1, and the two second motors are respectively used to drive the first crushing hub 51 and the second crushing hub 52 to rotate; the collecting assembly 3 comprises a collecting bin 31 detachably installed at the bottom of the preparation box 1 and a drawer 33 drawable and installed inside the collecting bin 31, and a baffle is arranged inside the drawer 33; a partition assembly is arranged inside the collecting bin 31, and the partition assembly comprises a partition 32 fixed inside the collecting bin 31, and the partition 32 is above the baffle.

[0029] As can be seen from the above, when in use, the concrete block is first placed into the hopper 4, and then the concrete is transported to the preparation box 1 through the hopper 4, and then the two second motors respectively drive the first crushing hub 51 and the second crushing hub 52 to rotate, so that the concrete is crushed by the rotation of the first crushing hub 51 and the second crushing hub 52 to realize the preparation of the concrete, and then the prepared concrete is transported to the collection bin 31 and the drawer 33. After the collection in the drawer 33 is completed, the staff pulls the pull rod to open the drawer 33 so as to collect the prepared concrete, so as to realize the unified storage and treatment of the prepared concrete. The structure and principle of concrete block preparation are prior art, and specific reference is made to the comparative document (announcement number is CN210496585U, and the patent name is an environmentally friendly ready-mixed concrete preparation device mixed with construction waste), which will not be repeated here.

[0030] refer to Figure 1 , Figure 2 and Figure 6 As shown, the sealing assembly 7 includes a sealing plate 71 movably mounted inside the hopper 4 and a linkage plate 73 rotatably mounted on one side of the hopper 4, a connecting rod is arranged between the linkage plate 73 and the sealing plate 71, an arc groove is provided on the hopper 4, and the connecting rod is in the arc groove; a power assembly is arranged on one side of the hopper 4, the power assembly includes a driven gear 75 rotatably mounted on the linkage plate 73 and a motor mounted on the top of the hopper 4, and a driving gear 74 meshing with the driven gear 75 is installed at one end of the motor; a protective assembly is arranged on the top of the hopper 4, and the protective assembly includes a protective box 72 covering the motor and the driven gear 75.

[0031] Through the above technical solution:

[0032] When it is necessary to seal the hopper 4, the driving gear 74 is driven to rotate by the motor. Since the driving gear 74 and the driven gear 75 are meshed, the driven gear 75 rotates with the rotation of the driving gear 74, and then the linkage plate 73 also rotates with the rotation of the driven gear 75. Therefore, the sealing plate 71 is also adjusted with the rotation of the linkage plate 73, so that the sealing plate 71 is in a vertical state to complete the sealing of the hopper 4, which can effectively prevent foreign matter from entering the preparation box 1 and affecting the preparation of concrete. At the same time, it can effectively block the dust inside the preparation box 1 to prevent dust from floating out and affecting the outside air, greatly improving the practicability of the device. Then, when it is necessary to open the hopper 4, the driving gear 74 is driven by the motor to rotate in the opposite direction, so that the sealing plate 71 is in a horizontal state in the hopper 4 to complete the opening of the hopper 4.

[0033] In addition, refer to Figure 1 , Figure 2 and Figure 5 As shown, a cleaning assembly 6 is provided inside the preparation box 1, and the cleaning assembly 6 includes a cleaning screen plate 61 detachably installed inside the preparation box 1 and a scraper plate 62 slidably installed on the top of the cleaning screen plate 61, the scraper plate 62 is in contact with the cleaning screen plate 61, and the cleaning screen plate 61 is below the first crushing hub 51 and the second crushing hub 52; an auxiliary pulling assembly is provided on one side of the scraper plate 62, and the auxiliary pulling assembly includes a pulling plate 63 installed on one side of the scraper plate 62, and the end of the pulling plate 63 away from the scraper plate 62 passes through the preparation box 1 and extends to the outside of the preparation box 1.

[0034] Through the above technical solution:

[0035] When the concrete is prepared and falls onto the cleaning sieve plate 61, the prepared concrete can be effectively filtered through the cleaning sieve plate 61, so that the collection component 3 can collect the prepared concrete, thereby facilitating the unified collection and storage of the concrete. Then the staff pulls the pull plate 63, so that the scraper 62 moves with the pulling of the pull plate 63. Since the scraper 62 contacts the cleaning sieve plate 61, the cleaning of the cleaning sieve plate 61 is completed through the movement of the scraper 62, which can effectively prevent the cleaning sieve plate 61 from being blocked, so that the cleaning sieve plate 61 can filter the prepared concrete for the subsequent use of the concrete, thereby greatly improving the practicality of the device.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
