Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0037] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. As Figures 1 to 3 shown, the present invention provides a cement mixing device, including: a support seat 2 provided with two spaced limiting grooves 22 thereon; further including a mixing drum 1, on which two limiting plates 12 cooperating with the mixing drum 1 are respectively provided, the limiting plates 12 can slide in the limiting grooves 22, and the mixing drum 1 is rotationally connected to the middle of the support seat 2; further including a locking device 3 for restricting and unlocking the relative sliding of the limiting plates 12 and the limiting grooves 22.

[0038] When using this cement mixing device, after tilting the empty mixing drum 1 to one side, use the locking device 3 to restrict the relative sliding of the limiting plates 12 and the limiting grooves 22, and fix the mixing drum 1 to tilt to one side. Feed through one side of the mixing drum 1. Since the height on this side is reduced, it is convenient for feeding and can improve the feeding efficiency. After the raw materials are put in, unlock the locking device 3 to make the limiting plates 12 and the limiting grooves 22 relatively slidable, and start to stir the raw materials forward and backward in the mixing drum 1 for a certain period of time. The center of gravity of the raw materials in the mixing drum 1 changes accordingly, driving the mixing drum 1 to tilt left and right, and making full use of the fluidity in the direction of gravity for stirring. After a period of time, when the stirring is completed, make the center of gravity of the raw materials in the mixing drum 1 be on the other side of the mixing drum 1, reducing the discharging height and improving the discharging efficiency.

[0039] In some optional embodiments, a card slot is provided on the limit plate 12, a receiving slot is provided in the support seat 2, and interconnected pin holes are provided in the vertical direction of the receiving slot. The locking device 3 includes: a tongue 31 provided in the receiving slot, the tongue 31 can be slidably provided in the receiving slot, and a driving slot 311 is provided on the tongue 31, and the driving slot 311 faces the pin hole; it also includes a recovery spring 33 provided in the receiving slot, one end of which is fixed in the receiving slot, and the other end is connected to the end of the tongue 31, so that the tongue 31 is retracted in the receiving slot; it also includes a pin 32 for being provided in the pin hole, and part of the pin 32 can extend out of the pin hole, and pressing the pin 32 can make it abut against the driving slot 311 to drive the tongue 31 to extend into the receiving slot.

[0040] In this embodiment, when the locking device 3 is used to limit the relative sliding of the limit plate 12 and the limit slot 22, when the limit plate 12 and the limit slot 22 slide to the positions of the card slot and the receiving slot, the part of the pin 32 extending outside the pin hole is pressed, and the pin 32 is pressed against the driving slot 311 of the tongue 31, so that the tongue 31 slides in the receiving slot until the tongue 31 is driven into the card slot, and the pin 32 is fixed to prevent it from sliding, so that the tongue 31 locks the position of the limit plate 12.

[0041] When the locking device 3 is used to release the locked state of the limit plate 12 and the limit slot 22, the fixation of the pin 32 is released, the pin 32 in the pin hole is pulled out, and the latch 32 is released from the driving slot 311. The recovery spring 33 will pull the tongue 31 back into the receiving slot, releasing the latch from the slot, thereby releasing the locked state of the limit plate 12 and the limit slot 22.

[0042] In addition, in this embodiment, the device for fixing the pin 32 can be provided with a limiting protrusion on the outer side of the support base 2 to accommodate the support base 2 so that it can slide, and a through hole is provided on the limiting protrusion, and a radial through hole is provided at the tail of the pin 32. A small pin is used to pass through the through hole of the limiting protrusion and the radial through hole provided at the tail of the pin 32 to fix the pin 32.

[0043] The inner surface of the driving groove 311 can be a slope or an arc surface. The side of the latch 32 that contacts the inner surface of the driving groove 311 is a slope. Pressing the latch 32 can drive the driving groove 311 to drive the tongue 31 to slide in the receiving groove.

[0044] In some optional embodiments, a buffer pad 23 is provided above the support seat 2 , and the thickness of the buffer pad 23 on both sides is greater than the thickness in the middle.

[0045] In this embodiment, the mixing drum 1 starts to mix the raw materials forward and backward within a certain period of time. As the center of gravity of the raw materials in the mixing drum 1 changes accordingly, when the mixing drum 1 is tilted left and right, it may collide with the support base 2. A buffer pad 23 is provided above the support base 2 to prevent the support base 2 from colliding violently with the mixing drum 1.

[0046] In some alternative embodiments, a buffer spring 24 is provided in the limiting groove 22, and one end of it is fixed below the limiting plate 12. In this embodiment, by providing the buffer spring 24 in the limiting groove 22, it can prevent the center of gravity of the raw materials in the mixing drum 1 from changing accordingly and avoid the limiting plate 12 from directly colliding with the support base 2 when the mixing drum 1 is tilted left and right.

[0047] In some alternative embodiments, the mixing drum 1 is provided with a feed inlet and is equipped with an inlet cover 13. The inlet cover 13 is hinged to the lower end of the feed inlet, and a locking device 14 is provided at the upper end of the feed inlet for fixedly connecting the upper end of the inlet cover 13 to the upper end of the feed inlet.

[0048] In this embodiment, the mixing drum 1 is provided with a feed inlet and is equipped with an inlet cover 13. The inlet cover 13 can be opened during feeding, and the locking device 14 locks the inlet cover 13 during mixing to prevent the concrete from spilling out of the mixing drum 1 when the mixing drum 1 is mixing.

[0049] See Figure 1 and Figure 4 As shown, in some alternative embodiments, the locking device 14 includes: a handle 141, the middle of which is hinged to the upper end of the feed inlet; a locking device 142 is also included, which is provided at one end of the handle 141 and is fixed above the mixing drum 1 for fixing and unlocking one end of the handle 141; a connecting rod 143 is also included, one end of which is hinged to the other end of the handle 141; a locking rod 144 is also included, which is provided at the other end of the connecting rod 143 and is perpendicular to the connecting rod 143. A clamping block 145 is also included, which is provided on the inlet cover 13 and has a downward groove. When the locking device 142 fixes the handle 141 on the mixing drum 1, the locking rod 144 is clamped in the groove. When the locking device 142 unlocks the handle 141, lifting the handle 141 can release the locking of the locking rod 144 from the groove.

[0050] In this embodiment, when the locking device 14 locks the inlet cover 13, the locking device 142 fixes one end of the handle 141 above the mixing drum 1, and the locking rod 144 is clamped in the groove. When unlocking, unlock the locking device 142, lift the handle 141 to rotate it by a certain angle along the hinge at the upper end of the feed inlet. One end of the connecting rod 143 rotates relative to the end of the handle 141, causing the connecting rod 143 to press down, so that the locking rod 144 is released from the groove, completing the unlocking of the locking device 14 for the inlet cover 13.

[0051] In this embodiment, the locking device 142 can be a device with a lock and a buckle, or a cooperation between a pin and a pin hole to achieve the effect of fixing one end of the handle 141 above the mixing drum 1 and unlocking.

[0052] See Figure 1 and Figure 5 As shown, in some alternative embodiments, a mixing device 11 and a motor 15 rotatably connected to the mixing device 11 are provided inside the mixing drum 1. The mixing device 11 includes a mixing shaft 111 and mixing blades 112 fixed on the mixing shaft 111, and the motor 15 is rotatably connected to the mixing shaft 111.

[0053] In this embodiment, when mixing is required, the motor 15 rotates to drive the mixing shaft 111 to rotate, so that the mixing blades 112 fixed on the mixing shaft 111 rotate to mix the concrete inside the mixing drum 1. In this embodiment, a controller 17 is provided above the motor 15. The controller is used to control the forward and reverse rotation and the rotation time of the motor 15. The forward and reverse rotation of the motor 15 causes the center of gravity of the raw materials inside the mixing drum 1 to change accordingly.

[0054] In some alternative embodiments, the mixing drum 1 is provided with a discharge port and is equipped with an outlet cover 19. The discharge port is located at the lower end of the motor 15. The upper end of the outlet cover 19 is hinged to the upper end of the discharge port. An electric telescopic rod 16 is provided between the lower side of the motor 15 and the middle and lower part of the outlet cover 19. The electric telescopic rod 16 is used to open and close the outlet cover 19.

[0055] In this embodiment, using the electric telescopic rod 16 to open the outlet cover 19 on the discharge port can avoid the risk to the operator caused by the overflow of concrete when the outlet cover 19 is opened manually, and can also improve the construction efficiency.

[0056] In some alternative embodiments, a hinge groove is provided in the middle of the lower part of the mixing drum 1, and a hinge ball 21 matching the hinge groove is provided in the middle of the support seat 2 to rotatably connect the mixing drum 1 and the support seat 2. In this embodiment, the support seat 2 and the mixing drum 1 are rotatably connected in a hinged form, with a simple structure and easy manufacturing.

[0057] In some alternative embodiments, a water inlet 18 is provided above one end of the mixing drum 1 where a feed inlet is provided. In this embodiment, by providing the water inlet 18 above one end of the mixing drum 1 where the feed inlet is provided, water can be added simultaneously during mixing or feeding, thereby improving the working efficiency.
