[0014] Furthermore, the material baffle assembly includes a pushing hydraulic cylinder fixedly installed on one side of the bracket.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model drives the adjusting cylinder to move up and down on the barrel body of the material cylinder through the lifting adjustment assembly, so that the volume between the adjusting cylinder and the material cylinder can be adjusted according to the proportion of the concrete raw materials.

The connecting plate can drive the linkage rod to rotate through the tooth groove and the linkage gear, and the linkage rod drives the rotating shaft to rotate through the reducer, so that the rotating shaft drives the rotating valve to rotate inside the discharge end of the material cylinder. This setting ensures that when the raw materials inside the material cylinder and the adjusting cylinder flow into the mixing assembly for mixing, the raw materials in one of the material cylinders will not all flow into the mixing assembly first due to the change of the proportion. Instead, when multiple raw materials are proportioned and mixed, the raw materials in multiple material cylinders can reach the bottom at the same time, so that the multiple raw materials can be better mixed together when the mixing assembly mixes the multiple raw materials.

[0020] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

[0033] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0034] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientations or positional relationships are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.

[0035] Please refer to Figures 1 - 9 As shown in the figure, the present utility model is a concrete batching machine for concrete production, including a base plate 1. A bracket 2 is fixedly connected to the top of the base plate 1. A plurality of cylinders 3 are fixedly connected to one side of the bracket 2. An adjusting cylinder 4 is sleeved on the outer surface of the cylinder 3. A lifting adjustment assembly 5 is arranged on one side of the adjusting cylinder 4. A flow rate control assembly 6 is arranged at the discharging end of the cylinder 3. A linkage assembly 7 is arranged between the flow rate control assembly 6 and the lifting adjustment assembly 5. A stirring assembly 8 is arranged at the bottom of the cylinder 3. A screw conveyor pipe 9 is arranged at the bottom end of the stirring assembly 8. A material blocking assembly 10 is arranged at the top of the bracket 2 and inside the cylinder 3.

[0036] When the ratio of concrete raw materials needs to be changed, directly drive the lifting and adjusting component 5, so that the adjusting cylinder 4 moves up and down on the barrel body of the material barrel 3 driven by the lifting and adjusting component 5, and the adjusting cylinder 4 is adjusted to a suitable position. During this process, the lifting and adjusting component 5 can drive the flow rate control component 6 through the linkage component 7, so that when the volume between the material barrel 3 and the adjusting cylinder 4 changes, the flow rate of the raw materials flowing out from the inside of the material barrel 3 will also change.

[0037] Drive the adjusting cylinder 4 to move up and down on the barrel body of the material barrel 3 through the lifting and adjusting component 5, so that the volume between the adjusting cylinder 4 and the material barrel 3 can be adjusted according to the ratio of concrete raw materials. In summary, when the ratio of concrete raw materials changes, directly drive the lifting and adjusting component 5, so that it is more convenient to adjust the volume between the material barrel 3 and the adjusting cylinder 4.

[0038] In one embodiment, for the above-mentioned lifting and adjusting component 5, the lifting and adjusting component 5 includes a lifting hydraulic cylinder 501, the lifting hydraulic cylinder 501 is fixedly installed on the top of the bottom plate 1, the output end of the lifting hydraulic cylinder 501 is fixedly connected with a connecting plate 502, the connecting plate 502 is fixedly connected with the adjusting cylinder 4, and a scale groove 503 is formed on the front surface of the connecting plate 502.

[0039] By driving the lifting hydraulic cylinder 501, the lifting hydraulic cylinder 501 drives the adjusting cylinder 4 to move on the barrel body of the material barrel 3 through the connecting plate 502. The scale groove 503 on the side at the bottom of the material barrel 3 represents the volume of the space formed between this position and the top of the adjusting cylinder 4. The above setting makes it more convenient for the operator to adjust the volume between the material barrel 3 and the adjusting cylinder 4 with the assistance of the scale groove 503.

[0040] In one embodiment, for the above-mentioned flow rate control component 6, the flow rate control component 6 includes a rotating shaft 601, the rotating shaft 601 is rotatably connected to the discharge end of the material barrel 3, a rotating valve 602 is fixedly connected to the outer surface of the rotating shaft 601, the rotating valve 602 is movably connected to the inner wall of the discharge end of the material barrel 3, the linkage component 7 includes a mounting plate 701, the mounting plate 701 is fixedly connected to the outer surface of the discharge end of the material barrel 3, a speed reducer 702 is fixedly installed on the top of the mounting plate 701, one end of the rotating shaft 601 is fixedly connected to the output end of the speed reducer 702, the output end of the speed reducer 702 is fixedly connected with a linkage rod 703, a linkage gear 704 is fixedly connected to the outer surface of the linkage rod 703, and a tooth groove 705 is formed on one side of the connecting plate 502, and the linkage gear 704 is engaged with the tooth groove 705.

[0041] When the connecting plate 502 moves up and down, the tooth grooves 705 on the connecting plate 502 can drive the linkage rod 703 to rotate through the linkage gear 704. The linkage rod 703 then drives the rotating shaft 601 to rotate through the speed reducer 702, so that the rotating shaft 601 drives the rotating valve 602 to rotate inside the discharge end of the barrel 3. As a result, when the space between the barrel 3 and the adjusting cylinder 4 changes, the degree of occlusion of the rotating valve 602 to the inside of the barrel 3 also changes accordingly. This setting ensures that when the raw materials in the barrel 3 and the adjusting cylinder 4 flow into the mixing component 8 for mixing, the raw materials in one barrel do not all flow into the mixing component 8 first due to the change in the ratio. Instead, when multiple raw materials are proportioned and mixed, the raw materials in multiple barrels 3 can bottom out simultaneously, enabling the mixing component 8 to better mix multiple raw materials together.

[0042] In one embodiment, for the above-mentioned mixing component 8, the mixing component 8 includes a conveying pipe 801, the conveying pipe 801 is fixedly connected to the discharge end of the barrel 3, a converging hopper 802 is fixedly connected to the bottom end of the conveying pipe 801, a mixing pipe 803 is fixedly connected to the bottom end of the converging hopper 802, a through groove 804 is formed in the inner wall of the mixing pipe 803, a connecting groove 813 is formed in the inner wall of the through groove 804, a connecting ring 805 is movably connected inside the through groove 804, a mixing roller 806 is fixedly connected to the inner wall of the connecting ring 805, a driving ring 807 is fixedly connected to the outer surface of the connecting ring 805, a driven gear 808 is fixedly connected to the outer surface of the driving ring 807, the driving ring 807 and the driven gear 808 are located inside the connecting groove 813. The mixing component 8 further includes a mounting frame 809, the mounting frame 809 is fixedly installed on the outer surface of the mixing pipe 803, a motor 810 is fixedly installed on the top of the mounting frame 809, a driving gear 811 is fixedly connected to the output end of the motor 810, a driving groove 812 corresponding to the driving gear 811 is formed in the inner wall of the connecting groove 813, and the driving gear 811 is engaged with the driven gear 808 through the driving groove 812.

[0043] The raw materials inside multiple barrels 3 can directly flow into the inside of the converging hopper 802 through the corresponding transport pipes 801 for preliminary convergence. At this time, the motor 810 drives the driven gear 808 to rotate through the driving gear 811. The driven gear 808 then drives the connecting ring 805 to rotate through the driving ring 807, so that the connecting ring 805 drives the stirring roller 806 to stir the various raw materials inside the converging hopper 802 and the stirring pipe 803. Since the stirring pipe 803 is inclined, the various raw materials are fully mixed together while flowing downward under the guidance of the stirring pipe 803. The mixed various raw materials directly flow into the inside of the spiral transport pipe 9. At this time, the spiral transport pipe 9 can directly transport the various raw materials preliminarily mixed together to the inside of the stirring device for secondary stirring. During the above working process, the connecting ring 805 contacts the top and bottom inner walls of the through groove 804, so that the raw materials flowing through the inside of the stirring pipe 803 will not leak. At the same time, the motor 810 outside the stirring pipe 803 can normally drive the connecting ring 805 to rotate inside the through groove 804 through the driving gear 811, the driving groove 812, the connecting groove 813, the driven gear 808 and the driving ring 807.

[0044] In one embodiment, for the above-mentioned material blocking assembly 10, the material blocking assembly 10 includes a pushing hydraulic cylinder 101. The pushing hydraulic cylinder 101 is fixedly installed on one side of the bracket 2. The output end of the pushing hydraulic cylinder 101 penetrates through the bracket 2 and is fixedly connected with a material blocking plate 102. A material blocking groove 103 is formed on the outer surface of the barrel 3. The material blocking plate 102 is movably connected with the material blocking groove 103. One side of the bracket 2 is movably connected with a guiding column 104. One end of the guiding column 104 is fixedly connected with the material blocking plate 102.

[0045] When batching, by driving the pushing hydraulic cylinder 101, the material blocking plate 102 can directly move into the inside of multiple material blocking grooves 103, so that when the raw materials are proportioned through the barrel 3 and the adjusting barrel 4, the raw materials will not flow into the inside of the transport pipe 801 through the discharge end, so that the accuracy of raw material proportioning can be guaranteed. At the same time, when the proportioned raw materials are preliminarily stirred, the material blocking plate 103 can no longer block the multiple barrels 3 synchronously under the drive of the pushing hydraulic cylinder 101, so that the raw materials inside the multiple barrels 3 can flow downward at the same time, so that the effect of stirring the various raw materials is better. In addition, the bottom of the barrel 3 is conical, and the material blocking groove 103 is arranged on the upper side of the conical position of the barrel 3. And because the boundary line between the upper side and the conical bottom of the barrel 3 is relatively obvious, it is also more convenient to check the space volume between the material blocking plate 102 inside the barrel 3 and the top of the adjusting barrel 4 through the scale groove 503 on the connecting plate 502.

[0046] In one embodiment, for the above-mentioned spiral conveying pipe 9, the spiral conveying pipe 9 is fixedly installed on the top of the bottom plate 1. A support leg 11 is fixedly connected to the top of the bottom plate 1, and the top end of the support leg 11 is fixedly connected to the bottom of the barrel 3.

[0047] By providing the spiral conveying pipe 9, it is convenient to transport the mixed raw materials into the interior of the mixing device. The cooperation between the support leg 11 and the bracket 2 can better support the barrel 3, thereby ensuring the stability of the barrel 3 during operation.

[0048] Through the above technical solutions: 1. The lifting and adjusting assembly 5 drives the adjusting cylinder 4 to move up and down on the barrel body of the barrel 3, so that the volume between the adjusting cylinder 4 and the barrel 3 can be adjusted according to the proportion of the concrete raw materials. In summary, when the proportion of the concrete raw materials changes, the lifting and adjusting assembly 5 can be directly driven, making it convenient to adjust the volume between the barrel 3 and the adjusting cylinder 4; 2. By setting the bottom of the barrel 3 to be conical, and the material blocking groove 103 is arranged above the conical position of the barrel 3. Since the boundary line between the upper side and the conical bottom of the barrel 3 is relatively obvious, the scale groove 503 at the boundary line represents the volume of the space formed by the material blocking plate 102 inside the barrel 3 and the top of the adjusting cylinder 4. The setting of the lifting hydraulic cylinder 501 and the scale groove 503 makes it convenient for the operator to adjust the volume between the material blocking plate 102 inside the barrel 3 and the top of the adjusting cylinder 4; 3. Through the linkage gear 704, when the connecting plate 502 drives the adjusting cylinder 4 to move up and down, the connecting plate 502 can drive the linkage rod 703 to rotate through the tooth groove 705 and the linkage gear 704. The linkage rod 703 drives the rotating shaft 601 to rotate through the speed reducer 702, so that the rotating shaft 601 drives the rotating valve 602 to rotate inside the discharge end of the barrel 3. This setting ensures that when the raw materials inside the barrel 3 and the adjusting cylinder 4 flow into the mixing assembly 8 for mixing, due to the change of the proportion, the raw materials in one of the barrels will not all flow into the mixing assembly 8 first. Instead, when multiple raw materials are proportioned and mixed, the raw materials in multiple barrels 3 can reach the bottom at the same time, enabling the mixing assembly 8 to better mix multiple raw materials together.
