[0047] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0048] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0049] like Figures 1 to 8As shown, the exemplary embodiment of the present application provides a stirring device, which includes a frame 1, a hopper 2, a conveying shaft 3 and a stirring drum 4. Figure 1 and 2 , the hopper 2 is fixed on the frame 1, so that the hopper 2 can be placed in an appropriate position according to actual construction requirements. The top of the hopper 2 is open to form a loading port 201 for loading materials, and the side wall of the hopper 2 is provided with a hopper discharge port. The hopper 2 as a whole can be extended in the horizontal direction, and its cross-section can be an inverted triangle or an inverted trapezoid, etc., so that the conveying shaft 3 can be extended along the length direction of the hopper 2 and arranged in the hopper 2, for example, it is set in the bottom space of the hopper 2. When the conveying shaft 3 rotates, the material can be pushed to the hopper discharge port. The mixing drum 4 is detachably connected to the hopper 2 and is in communication with the hopper discharge port, so that the material can enter the mixing drum 4 from the hopper 2 through the hopper discharge port.

[0050] Thus, the mixing device of the exemplary embodiment can be used to prepare mixed products such as dry-mixed mortar. Specifically, the material can be put into the hopper 2 through the feeding port 201 by manually bagging the material, so that the material to be mixed can be gathered in the hopper 2, and then the material is transported to the mixing drum 4 through the conveying shaft 3 for water addition and mixing, thereby completing the preparation of dry-mixed mortar.

[0051] It can be seen that the stirring device of this embodiment can integrate the functions of the feeding device and the conveying device into the hopper 2, realize the feeding and conveying operation of small batches of materials, and no additional feeding equipment such as mobile silos is required for feeding, thereby optimizing the structure of the stirring device and reducing the overall volume of the stirring device, which can be used for on-site preparation of construction materials such as dry-mixed mortar in small spaces such as indoors. In addition, the mixing drum 4 and the hopper 2 can be disassembled for easy transportation and storage, further improving the convenience of device layout.

[0052] In an optional or preferred embodiment, referring to Figure 1 and Figure 2 The frame 1 includes a support mechanism 101 and a walking mechanism 102 arranged at the bottom of the frame, wherein the support mechanism 101 is fixedly connected to one end of the hopper 2, and the walking mechanism 102 is fixedly connected to the other end of the hopper 2. Therefore, when the stirring device of this embodiment needs to be moved, the support mechanism 101 only needs to be lifted upward to push the stirring device to move, which greatly improves the convenience of the device transfer and effectively expands the construction operation range.

[0053] In other embodiments, two walking mechanisms 102 may also be provided, and the two walking mechanisms 102 are respectively connected to the two ends of the hopper 2. Therefore, when the stirring device of this embodiment needs to be moved, the stirring device can be moved by only pushing the hopper 2.

[0054] In the above embodiment, the walking mechanism 102 may include a pulley assembly rotatably connected to the bottom of the frame. In order to prevent the hopper 2 from being displaced during the mixing operation, a stopping device, such as a brake, a locking device, etc., may be provided in the walking mechanism 102, which is not limited in this embodiment.

[0055] In an optional or preferred embodiment, referring to Figure 3 The stirring device includes a quick-release structure 5, which includes a first clamping portion arranged on the side wall of the hopper 2 and a second clamping portion arranged on the peripheral wall of the stirring drum 4. When the stirring drum 4 is connected to the hopper 2, the first clamping portion and the second clamping portion can be clamped with each other to lock the hopper 2 and the stirring drum 4.

[0056] Specifically, one of the first clamping portion and the second clamping portion can be formed as a clamping block 501 and the other can be formed as a clamping arm 502, and the clamping arm 502 is provided with a clamping groove for clamping the clamping block 501. Figure 3 As shown, when the first clamping portion is formed as a clamping block 501 and the second clamping portion is formed as a clamping arm 502, during the installation of the mixing drum 4, the mixing drum 4 can be moved to align the clamping groove with the clamping block 501, and the clamping groove is inserted into the clamping block 501, so that the mixing drum 4 can be fixedly installed on the hopper 2, which is convenient and quick.

[0057] exist Figure 3 In the illustrated embodiment, the hopper 2 includes a quantitative feeding barrel 6 which is arranged on the side wall of the hopper 2 and is aligned and connected with the hopper discharge port, and the first clamping portion is arranged on the peripheral wall of the quantitative feeding barrel 6. Specifically, the clamping block 501 can be arranged to extend along the circumference of the quantitative feeding barrel 6, and correspondingly, the clamping arm 502 can be arranged to extend along the axial direction of the mixing drum 4, and the clamping groove penetrates the clamping arm 502 along the circumference of the mixing drum 4. Therefore, in the process of installing the mixing drum 4, after aligning the clamping groove with the clamping block 501, the mixing drum 4 can be rotated along the circumference to insert the clamping groove into the clamping block 501, so that the clamping block 501 and the clamping arm 502 are clamped with each other, and the installation of the mixing drum 4 can be completed. In this embodiment, a plurality of clamping blocks 501 and a plurality of clamping arms 502 can be respectively provided, and the plurality of clamping blocks 501 and the plurality of clamping arms 502 correspond one to one, for example Figure 3 As shown, two clamping blocks 501 are provided on the peripheral wall of the quantitative feeding cylinder 6, and two corresponding clamping arms 502 are provided on the peripheral wall of the mixing cylinder 4. The present application does not limit the number of the clamping blocks 501 and the clamping arms 502, as long as the installation and locking requirements can be met.

[0058] Preferably, the clamping block 501 is a wedge-shaped clamping block, and the clamping groove is a square clamping groove. The clamping groove can be inserted from the narrow end of the wedge-shaped clamping block to gradually clamp the wedge-shaped clamping block.

[0059] Furthermore, in order to improve the stability of the mixing drum 4, the clamping arm 502 is provided with a clamping screw hole that passes through the side wall of the clamping groove, and the quick-release structure 5 also includes a clamping bolt 503 that matches the clamping screw hole. When the clamping block 501 is clamped in the clamping groove, the clamping bolt 503 can be passed through the clamping screw hole to compress the clamping block 501 in the clamping groove, thereby improving the stability of the mixing drum 4. Figure 3 In the illustrated embodiment, the clamping bolt 503 is used in conjunction with the nut 504 .

[0060] exist Figure 1 In the illustrated embodiment, the stirring device includes a stirring shaft 7 disposed in a stirring drum 4, and a plurality of stirring blades for uniformly mixing the material and water are disposed on the peripheral wall of the stirring shaft 7. The key point is that the stirring shaft 7 is detachably connected to the conveying shaft 3. For example, one end of the stirring shaft 7 can be set as a plug end, and one end of the conveying shaft 3 can be set as a shaft hole end. By plugging the stirring shaft 7 into the conveying shaft 3, the detachable connection between the two can be achieved. Thus, after the stirring drum 4 is disassembled, the stirring shaft 7 can be further disassembled from the conveying shaft 3, so that the stirring drum 4 and the stirring shaft 7 can be easily cleaned. In the case where the hopper 2 is provided with a quantitative feeding drum 6, the quantitative feeding drum 6 can also be easily cleaned by disassembling the stirring drum 4 and the stirring shaft 7. In addition, the construction personnel can replace the stirring shaft 7 with different stirring capacities according to the actual construction requirements, so as to meet the preparation requirements of mortar products with different proportions.

[0061] exist Figure 4 In the illustrated embodiment, the conveying shaft 3 includes a first shaft section 301 and a second shaft section 302 which are detachably connected to each other, wherein the peripheral wall of the first shaft section 301 is provided with a plurality of first spiral blades 303 which are sequentially spaced along the axial direction of the first shaft section 301, and the peripheral wall of the second shaft section 302 is provided with a second spiral blade 304 which extends along the axial direction of the second shaft section 302, the first spiral blade 303 is a discontinuous spiral blade, and the second spiral blade 304 is a continuous spiral blade. Thus, when the conveying shaft 3 is rotated, the material in the hopper 2 can move toward the hopper discharge port under the push of the plurality of first spiral blades 303 and the second spiral blade 304, and then be conveyed to the mixing drum 4. In the above conveying process, the material can be pre-pushed by the plurality of first spiral blades 303 on the first shaft section 301 to obtain the initial velocity, and then quantitatively pushed by the second spiral blade 304 on the second shaft section 302, thereby realizing a continuous and quantitative conveying operation. More importantly, construction personnel can replace the second shaft section 302 with different conveying capacities according to actual construction requirements, thereby changing the material conveying flow rate to meet the preparation requirements of mortar products with different proportions.

[0062] Specifically, Figure 5 and Figure 6As shown, one end of the first shaft segment 301 is formed as a sleeve end 3011 , and one end of the second shaft segment 302 is formed as a plug-in end 3021 . The plug-in end 3021 can be plug-fitted with the sleeve end 3011 , so that the second shaft segment 302 can be connected to the first shaft segment 301 .

[0063] Alternatively, in other embodiments, one end of the first shaft segment 301 is formed as a plug-in end 3021, and one end of the second shaft segment 302 is formed as a sleeve end 3011. By sleeve-fitting the sleeve end 3011 onto the plug-in end 3021, the second shaft segment 302 and the first shaft segment 301 can also be connected to each other.

[0064] Furthermore, in order to improve the stability of the connection between the second shaft section 302 and the first shaft section 301, the sleeve end 3011 and the plug end 3021 are both formed with through holes, and the stirring device further includes a conveying shaft connecting piece 8 for connecting the sleeve end 3011 and the plug end 3021. Thus, when the second shaft section 302 and the first shaft section 301 form a plug-in fit, the conveying shaft connecting piece 8 sequentially connects the through holes of the two, thereby achieving a fixed connection between the second shaft section 302 and the first shaft section 301. Preferably, the through hole is a screw hole, and the conveying shaft connecting piece 8 is a bolt assembly, and the screw hole is connected by the bolt assembly to facilitate the disassembly of the second shaft section 302.

[0065] exist Figure 4 and Figure 5 In the illustrated embodiment, the first shaft section 301 is further provided with a plurality of dispersing blades 305, wherein a portion of the dispersing blades 305 may be provided on the peripheral wall of the first shaft section 301, and another portion of the dispersing blades 305 may be provided at the outer ends of the first spiral blades 303. By providing a plurality of dispersing blades 305, the accumulated or agglomerated materials can be dispersed, making the conveying process smoother and avoiding the jamming of the conveying shaft 3 and affecting the mixing operation.

[0066] In addition, according to the actual conveying length, multiple first shaft segments 301 and multiple second shaft segments 302 can be set, so as to increase the total length of the conveying shaft 3. This embodiment does not limit the combination of the first shaft segment 301 and the second shaft segment 302. At the same time, when the length of the second spiral blade 304 is short, the second shaft segment 302 can also be appropriately provided with a certain number of first spiral blades 303 to meet the conveying requirements, avoid a large gap between the second spiral blade 304 and the first spiral blade 303, and ensure that the material can be continuously conveyed.

[0067] Preferably, if Figure 1As shown, the portion of the second shaft segment 302 provided with the second spiral blade 304 is disposed in the quantitative feeding barrel 6, and the remaining portion without the second spiral blade 304 and the first shaft segment 301 can be disposed in the hopper 2. In other embodiments, when the quantitative feeding barrel 6 is not disposed in the hopper 2, or when the quantitative feeding barrel 6 is disposed inside the hopper 2, both the first shaft segment 301 and the second shaft segment 302 can be disposed in the hopper 2, and this application does not limit this.

[0068] In an optional or preferred embodiment, Figure 1 As shown, a water injection port 401 is provided on the peripheral wall of the mixing drum 4, and the mixing device further comprises a water supply system 9 arranged on the frame 1, and the water supply system 9 is connected to the water injection port 401 through a pipeline for injecting water into the mixing drum 4. Figure 8 The water supply system 9 can be composed of a pressure reducing valve 901, a solenoid valve 902 and a needle valve 903 which are connected in sequence through a pipeline. Specifically, they can be connected in sequence through a water pipe 904. The water inlet and the water outlet of the water pipe 904 are respectively connected to the water source and the water injection port 401 of the mixing drum 4. Therefore, the pressure reducing valve 901 can stabilize the water circuit pressure. When it is necessary to inject water into the mixing drum 4, water supply can be achieved by starting the solenoid valve 902. At the same time, the water supply flow rate can be adjusted by adjusting the opening of the needle valve 903, so as to achieve proportional water addition. Overall, the number of components of the water supply system 9 is relatively small, which effectively reduces the manufacturing cost.

[0069] In an optional or preferred embodiment, Figure 1 As shown, the stirring device also includes a driving mechanism 10 disposed on the frame 1, and the driving mechanism 10 is used to drive the conveying shaft 3 to rotate to push the material. Figure 7 , the driving mechanism 10 includes a motor 1001 and a reducer 1002, wherein the output shaft of the motor 1001 is connected to the conveying shaft 3 through the reducer 1002, so that the motor 1001 can run smoothly and the conveying shaft 3 can rotate at a uniform speed. In this embodiment, the reducer 1002 includes a driving wheel and a driven wheel, the circumference of the driving wheel is set to be smaller than the driven wheel, the driving wheel and the driven wheel are connected by a transmission belt such as a belt, the output shaft of the motor 1001 is connected to the driving wheel, and the conveying shaft 3 is connected to the driven wheel. By adopting the motor-belt transmission mode, the operating noise of the device can be reduced, and the overload protection function is played, effectively preventing other parts from being damaged. Of course, the present application is not limited to the reducer 1002 with belt drive, and other reduction devices that can play the role of reducing speed and increasing torque can be used as the reducer 1002 of the present application.

[0070] Furthermore, if Figure 1 As shown, the stirring device may also be provided with an electric control system 11 for controlling the start and stop of the driving mechanism 10 or the water supply system 9, so as to realize the start, stop and reset of the entire stirring device, thereby improving the degree of automation.
