Description

TECHNICAL FIELD

[0001] The present application relates to the cement loading and unloading technical field, in particular to a cement loading and unloading vehicle. BACKGROUND

[0002] The cement loading and unloading vehicle refers to the loading and unloading of the cement at the construction site, aiming to improve the applicability of the cement loading and unloading. The traditional cement loading and unloading is transported by manpower, and the cement is transported to the destination. The cement loading and unloading vehicle is a new type of loading and unloading tool, which only needs to load the cement into the vehicle compartment to complete the transportation.

[0003] In the construction of high-rise buildings, the cement is scooped into a small cart by manpower, and the cement is sent to the destination by manpower pushing, and finally the cart is turned over to pour out the cement. This process greatly consumes the labor cost and is not easy to completely clean the inner wall of the vehicle compartment, resulting in waste of part of the cement. In the current cement pavement damage repair process, a small amount of cement needs to be transported to the to-be-repaired pavement for many times. It is difficult to predict the total amount of cement needed, but it is difficult to add cement temporarily during the construction process. In the current cement transportation process at the construction site, due to the large construction area, the cement transportation distance is long, so the cement transportation time is also long. Over a long period of time, the cement will solidify in the vehicle compartment due to lack of stirring, and it is difficult to maintain the original viscosity and fluidity. Under the long-time transportation, the cement will adhere to the bottom and inner wall of the vehicle compartment, and it is difficult to pour out for use. At the same time, in the secondary transportation process, part of the cement will be affected by the last solidified cement, which will reduce the quality of the cement to be used next time.

[0004] Therefore, the prior art discloses a cement mixer truck, which sets a centrifugal vibrator on the unloading device. When unloading, the vibrator works to accelerate the flow rate of the cement to prevent the cement from adhering to the inner wall of the vehicle compartment. The invention solves the problem that the cement in the vehicle compartment cannot be completely unloaded during unloading, but the cement poured out by vibration still has the phenomenon of sticking to the wall, which affects the quality of the cement for secondary transportation. Cleaning after each transportation greatly increases the labor cost.

[0005] In view of this, the present application designs a cement loading and unloading vehicle to solve the above problems. SUMMARY

[0006] The technical problem to be solved by the present application is how to temporarily load cement during construction and reduce cement residue when unloading.

[0007] This invention provides a cement loading and unloading vehicle, comprising a tank cover, a drive motor, a loading and unloading vehicle body, a mixing component, a power component, and a locking component. The drive motor is fixedly connected to the bottom of the loading and unloading vehicle body, thereby enabling the drive motor to be positioned and supported. The mixing component is fixedly mounted on the drive motor, thereby enabling the drive motor to drive the mixing component to rotate along the axis of the drive motor output shaft while simultaneously translating in the vertical direction. The mixing component is fixedly mounted with a power component for separating or joining the mixing component via a screw, thereby enabling the mixing component to drive the power component to move when translating. The tank cover is fixedly mounted on the power component, and the locking component is fixedly mounted on the loading and unloading vehicle body. The locking component is displaced along its own axial direction under the drive of the power component, thereby locking the loading and unloading vehicle body to prevent slippage. Thus, when the power component lifts the tank cover to pour cement into the loading and unloading vehicle body, the locking component clamps the moving component, preventing the cement loading and unloading vehicle from moving during feeding.

[0008] When the cement loading and unloading truck is transporting cement, the motion component drives the movement of the truck body, while the drive motor drives the mixing component to stir the cement inside the truck body, preventing it from clumping or adhering to the inner wall of the truck body during transportation. When feeding is required, the mixing component drives the power component to move, the power component lifts the lid, and the cement is poured into the truck body. At the same time, the power component drives the locking component to clamp the motion component, preventing the horizontal thrust generated when the cement is poured into the truck body from causing horizontal displacement of the cement loading and unloading truck. After the feeding process is completed, the power component drives the locking component to release the motion component, which in turn causes the motion component to move the cement loading and unloading truck. When discharging is required, the movement of the mixing component cleans the inner wall of the truck body and pushes the cement to the bottom of the truck body.

[0009] Preferably, the mixing assembly includes a main shaft, a stirring rod, a rotating sleeve, a movable sleeve, and a connecting rod. The output shaft of the drive motor is fixedly connected to the main shaft, and the main shaft is fixedly connected to the rotating sleeve, thereby enabling the main shaft to transmit the torque of the drive motor to the rotating sleeve. The rotating sleeve is fixedly connected to the movable sleeve near the bottom of the loading and unloading vehicle body, thereby enabling the movable sleeve to move through the sliding of the power assembly. Simultaneously, the transmission sleeve, along with the locking assembly locking the loading and unloading vehicle body, synchronously separates the cover from the vehicle body. When the loading and unloading vehicle body needs to stop moving, the drive motor reverses, and the rotating sleeve drives the movable sleeve to control the movement of the locking assembly, which locks the cover. The stirring rod is fixedly connected to the outer wall of the rotating sleeve, thereby achieving mixing. The mixing rod mixes the solid and liquid components of cement through its rotation, preventing the cement from solidifying. The mixing rod is T-shaped, with a frustum-shaped section near the bottom of the loading / unloading vehicle. The mixing rod is installed on the main shaft near the locking assembly, allowing it to better push the cement towards the discharge port through the frustum-shaped bottom when the mixing rod reverses. A connecting rod is fixedly connected to the outer wall of the moving bushing, with a limit hole at the connecting rod. A power assembly is detachably fixed to the connecting rod near the tank cover. When the connecting rod is separated from the power assembly at the tank cover, the power assembly does not work. When the loading / unloading vehicle needs to brake, the connecting rod connects to the power assembly at the tank cover, thereby braking the loading / unloading vehicle while simultaneously lifting and separating the tank cover from the loading / unloading vehicle.

[0010] The drive motor is an AC asynchronous motor, enabling the main shaft to rotate clockwise or counterclockwise. The main shaft has an external thread in its middle section, and the rotating sleeve has an internal thread on its inner wall. This allows the rotating sleeve to rotate around the main shaft's axis and translate along it when the main shaft rotates. The main shaft is a stepped shaft with a larger diameter at the end near the drive motor. The stirring rod is T-shaped and fixedly connected to the main shaft near the drive motor. The main shaft drives the stirring rod to rotate, ensuring thorough mixing of the cement during transport and preventing clumping. Simultaneously, the stirring rod drives the rotating sleeve to rotate, improving its working efficiency. The rotation of the bushing drives the moving component to rotate via a thread. The thread between the rotating bushing and the moving bushing is smaller than the thread between the main shaft and the rotating bushing. This allows the rotating bushing to drive the moving bushing in two parts: first, the moving bushing rotates and translates along the main shaft; second, the moving bushing only translates along the main shaft without rotating. When the moving bushing drives the connecting rod to rotate, the connecting rod stirs the cement in the truck bed. The direction of rotation of the connecting rod is opposite to that of the stirring rod, which helps to improve the stirring effect. When the moving bushing does not rotate but only translates, the moving bushing drives the connecting rod to move. The connecting rod connects to the power component, which in turn drives the power component to translate.

[0011] During the movement of the cement loading and unloading truck, the drive motor starts and drives the main shaft to move. The main shaft drives the rotating bushing to make a circular motion around the axis of the main shaft and to move horizontally along the axis of the main shaft. At the same time, the main shaft drives the mixing rod to rotate, mixing the cement in the truck bed. The rotating bushing drives the moving bushing to make a circular motion around the axis of the main shaft and to move horizontally along the axis of the main shaft. Therefore, the connecting rod mixes the cement in the truck bed, and the mixing direction is different from that of the mixing rod. When the moving bushing does not rotate but only moves horizontally, the connecting rod is connected to the power component, driving the power component to move horizontally.

[0012] Preferably, the power assembly includes a transmission rack, a protrusion, an idler gear, a control rack, a paddle shifter, and a rocker arm. A connecting rod is slidably connected to the protrusion, and the connecting rod has a groove to allow it to engage with the protrusion at its upper limit position, thus enabling the connecting rod to drive the protrusion. A limit rod is provided on the protrusion, with the side of the limit rod near the connecting rod made of flexible material. The limit rod is detachably fixed to the connecting rod, so that when the stirring rod rotates to the limit rod, the limit rod deforms and is fixedly connected to the limit hole, thereby enhancing the locking effect on the loading / unloading vehicle body. The protrusion is welded or keyed. A transmission rack is connected, and the protrusion drives the transmission rack to move. The transmission rack meshes with an idler wheel, which in turn meshes with a control rack. The transmission rack transmits power to the control rack through the idler wheel. The teeth of the control rack near the cover are hook-shaped. The inner wall of the carriage is equipped with hooks to prevent the control rack from slipping. One end of the transmission rack is welded or threaded with a lever for lifting the cover. The end of the control rack away from the lever is welded with a rocker arm for controlling the operation of the locking assembly. The side of the rocker arm near the control rack is kept horizontal with the connecting rod. The rocker arm controls the movement of the locking assembly as the connecting rod rotates.

[0013] When the cement loading and unloading truck needs to be fed, the connecting rod drives the protrusion to move, which in turn drives the rack to move closer to the box cover. The paddle lifts the box cover, and the cement is poured into the truck. At the same time, the rack is controlled to move away from the box cover, which in turn drives the swing arm to move. The swing arm drives the clamping assembly to clamp the moving assembly, preventing the moving assembly from moving the cement loading and unloading truck. When feeding is finished, the rack moves away from the box cover, which achieves a clearance fit between the box cover and the truck to prevent cement from splashing out. At the same time, the rack is controlled to move closer to the box cover, which in turn drives the swing arm to control the clamping assembly to release the moving assembly.

[0014] Preferably, the locking assembly includes a control rod, a cam plate, a limit plate, a locking pawl, and a limit bracket. A control rod is fixedly connected to the side of the rocker arm away from the control rack, thereby enabling the control rod to control the operation of the clamping assembly. The control rod is fixedly connected to the cam plate, and a spherical block is provided on the control rod. The spherical block is on the same plane as the main shaft, thereby enabling the control rod to slide on a locking pawl. A deformable part is provided on the side of the locking pawl near the limit plate, and the deformable part is slidably connected to the connecting rod. The deformable part is made of rubber, thereby improving the locking effect of the locking pawl. This is useful during the operation of cement loading and unloading trucks. During the process, the deformation part can clean the limiting plate. At the same time, some cement will adhere to the deformation part, which improves the hardness and service life of the deformation part. The locking pawl contacts the limiting plate, thereby realizing the control rod driving the locking pawl to work. The locking pawl contacts the limiting plate, and the limiting plate contacts the drive wheel, thereby realizing the drive wheel being clamped by the limiting plate. A locking hole is opened in the limiting frame. The axis of the locking hole is corrugated. The locking hole is slidably connected to the connecting rod. The connection point between the locking hole and the connecting rod is located at the maximum curvature of the locking hole, thereby realizing the automatic locking of the connecting rod by the locking hole.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. A cement loading and unloading vehicle of the present invention, the equipment uses the principle of power transmission to do work, and then uses the cooperation of power components and locking components to prevent the cement loading and unloading vehicle from horizontal displacement caused by the impact of cement during the cement loading process, and automatically opens the box cover, thereby improving the working efficiency of the cement loading and unloading vehicle.

[0017] 2. A cement loading and unloading vehicle of the present invention, wherein the device changes the power transmission direction by means of a threaded drive, and then utilizes the cooperation between the mixing component and the loading and unloading vehicle body to complete the mixing of cement by the movement of the mixing component itself, while cleaning the inner wall of the loading and unloading vehicle body, thereby preventing cement from sticking together and causing a decline in cement quality during the next cement transport.

[0018] 3. A cement loading and unloading vehicle of the present invention, wherein the equipment, through the directional movement of the mixing component, and by utilizing the cooperation between the mixing component and the loading and unloading vehicle body, realizes that when unloading cement, the mixing component pushes the cement in the loading and unloading vehicle body to the discharge port, thereby improving the cement discharge speed and reducing cement waste.

[0029] To make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-2 As shown, the present invention provides a cement loading and unloading vehicle, including a tank cover 1, a drive motor 2, a loading and unloading vehicle body 3, a mixing component 4, a power component 5, and a locking component 6. The drive motor 2 is fixedly connected to the bottom of the loading and unloading vehicle body 3, thereby realizing the positioning and bearing of the drive motor 2. The mixing component 4 is fixedly installed on the drive motor 2, thereby realizing that the drive motor 2 drives the mixing component 4 to rotate along the axis of the output shaft of the drive motor 2 while translating in the vertical direction. The mixing component 4 is fixedly installed with a power component 5 for separating or joining the mixing component 4 through a screw, thereby realizing that the mixing component 4 drives the power component 5 to move when translating. The tank cover 1 is fixedly installed on the power component 5, and the locking component 6 is fixedly installed on the loading and unloading vehicle body 3. The locking component 6 generates displacement along its own axis under the drive of the power component 5, thereby locking the loading and unloading vehicle body 3 to prevent the loading and unloading vehicle body 3 from slipping. Thus, when the power component 5 lifts the tank cover 1 to pour cement into the loading and unloading vehicle body 3, the locking component 6 clamps the moving component, preventing the cement loading and unloading vehicle from moving during feeding.

[0031] When the cement loading and unloading truck is transporting cement, the motion component drives the movement of the loading and unloading truck body 3, while the drive motor 2 drives the mixing component 4 to move, thereby stirring the cement inside the loading and unloading truck body 3 and preventing the cement from clumping or adhering to the inner wall of the loading and unloading truck body 3 during transportation. When feeding is required, the mixing component 4 drives the power component 5 to move, and the power component 5 lifts the box cover 1, allowing the cement to be poured into the loading and unloading truck body 3. At the same time, the power component 5 drives the locking component 6 to clamp the motion component, preventing the cement loading and unloading truck from shifting horizontally due to the horizontal thrust generated when the cement is poured into the loading and unloading truck body 3. After the feeding process is completed, the power component 5 drives the locking component 6 to release the motion component, thereby allowing the motion component to drive the cement loading and unloading truck to move. When discharging is required, the movement of the mixing component 4 cleans the inner wall of the loading and unloading truck body 3 and pushes the cement to the bottom of the loading and unloading truck body 3.

[0032] While existing technologies include equipment capable of cleaning the inner walls of cement loading and unloading trucks, most of these methods rely on vibrators to vibrate the truck body. Furthermore, the unloading of cement depends solely on its own weight, making it difficult to completely remove the cement. Cement residue not only degrades the quality of cement transported in subsequent trips but also results in unnecessary waste. Therefore, changing the method of unloading cement is crucial. This application cleans the inner walls of the truck compartment 32 through the movement of the mixing component 4, thereby reducing the amount of cement residue.

[0033] like Figures 3 to 4As shown, the output shaft of the drive motor 2 is connected to the main shaft 41 via a coupling. The main shaft 41 is threaded with a rotating sleeve 43, which is fixedly connected to the main shaft 41. This allows the main shaft 41 to transmit the torque of the drive motor 2 to the rotating sleeve 43. A movable sleeve 44 is fixedly connected to the rotating sleeve 43 near the bottom of the loading / unloading vehicle body 3. This allows the movable sleeve 44 to move via the sliding of the power component 5. Consequently, the transmission sleeve, along with the locking component 6 locking the loading / unloading vehicle body 3, synchronously separates the box cover 1 from the loading / unloading vehicle body 3. This allows the loading / unloading vehicle body 3 to stop moving when the drive motor 2 reverses, and the rotating sleeve 43 drives the movable sleeve 44 to control the movement of the locking component 6. The locking component 6 locks the box cover 1. A stirring rod 42 is fixedly connected to the outer wall of the rotating sleeve 43, allowing the stirring rod 42 to... The mixing rod 42 is T-shaped and is set into a frustum shape near the bottom of the loading and unloading vehicle body 3. The mixing rod 42 is installed on the main shaft 41 near the locking component 6, so that the mixing rod 42 can better push the cement to the discharge port through the frustum bottom when it reverses. A connecting rod 45 is fixedly connected to the outer wall of the moving bushing 44. A limit hole is opened at the connecting rod 45. A power component 5 is detachably fixedly installed on the connecting rod 45 near the box cover 1. When the connecting rod 45 is separated from the power component 5 at the box cover 1, the power component 5 does not work. When the loading and unloading vehicle body 3 needs to brake, the connecting rod 45 and the power component 5 are connected at the box cover 1, so as to achieve braking of the loading and unloading vehicle body 3 and lifting and separating the box cover 1 from the loading and unloading vehicle body 3.

[0034] The main shaft 41 has an external thread in its middle section, and the inner wall of the rotating sleeve 43 has an internal thread with a pitch of 8mm and 10 turns. This allows the rotating sleeve 43 to rotate around the axis of the main shaft 41 and translate along the axis of the main shaft 41 when the main shaft 41 rotates. The main shaft 41 is a stepped shaft with two sections: the first section has a diameter of 270mm and a length of 90mm, and the second section has a diameter of 90mm and a length of 720mm. The stirring rod 42 is T-shaped, with a horizontal section of 400mm and a vertical section of 640mm, both with a diameter of 80mm. The stirring rod 42 is welded to the end of the main shaft 41 near the drive motor 2. The main shaft 41 drives the stirring rod 42 to rotate, thus ensuring that the cement is fully mixed during transportation and preventing cement from clumping. At the same time, the stirring rod 42 drives the rotating sleeve to rotate, improving the working efficiency of the rotating sleeve 43. Since the stirring rod 42 not only needs to mix the cement but also needs to transmit the cement... A portion of the torque is transmitted to the rotating bushing 43, causing it to rotate. Therefore, welding is required to improve the working reliability of the stirring rod 42. The rotation of the rotating bushing 43 drives the moving component to rotate via a thread. The thread between the rotating bushing 43 and the moving bushing 44 is smaller than the thread between the main shaft 41 and the rotating bushing. This allows the rotating bushing to drive the moving bushing 44 to move in two parts: the first part is that the moving bushing 44 rotates and translates along the direction of the main shaft 41; the second part is that the moving bushing 44 only translates along the direction of the main shaft 41 and does not rotate. When the moving bushing 44 drives the connecting rod 45 to rotate, the connecting rod 45 stirs the cement in the truck bed 32. The rotation direction of the connecting rod 45 is opposite to that of the stirring rod 42, which helps to improve the stirring effect. When the moving bushing 44 does not rotate but only translates, the moving bushing 44 drives the connecting rod 45 to move. The connecting rod 45 is connected to the power component 5, which in turn drives the power component 5 to translate.

[0035] like Figures 5 to 6As shown, the connecting rod 45 is slidably connected to a protrusion 51. The protrusion 51 is a cuboid, 160mm long, 80mm wide, and 40mm thick. Since it is necessary to transmit the power of the mixing component 4 to the power component 5, it requires high fatigue strength. Therefore, the protrusion 51 is made of 40Cr material, with surface quenching and annealing treatment. The connecting rod 45 has a groove with a length of 80mm and a width of 40mm. The technical requirement for machining the groove is that the lower deviation should not exceed 0.03mm to prevent the connecting rod 45 from failing to cooperate with the protrusion 51. This allows the connecting rod 45 to move with the protrusion 51 when it moves to the upper limit position, thereby enabling the connecting rod 45 to drive the protrusion 51 to move. The protrusion 51 is keyed to a transmission rack 52. Since the protrusion 51 needs to bear a large load and the working environment contains alkaline substances such as cement, the working environment of the protrusion 51 is harsh. The replaceability of the protrusion 51 needs to be considered. Therefore, a key connection is used for fixation. The key is a type A flat key to ensure the interchangeability of the key. The protrusion 51 drives the transmission rack 52 to move. The transmission rack 52 meshes with the idler wheel 53, and the idler wheel 53 meshes with the control rack 54. The transmission rack 52 transmits power to the control rack 54 through the idler wheel 53. One end of the transmission rack 52 is welded with a lever 55 for lifting the box cover 1. The end of the control rack 54 away from the lever 55 is welded with a rocker arm 56 for controlling the operation of the locking assembly 7. Since the transmission rack 52, the control rack 54, the lever 55, and the rocker arm 56 are made of different materials, welding is used to ensure the reliability of the fixed connection. The control rack 54 has hook-shaped teeth near the end of the box cover 1. The inner wall of the cargo box 32 is equipped with hook claws 33 to prevent the control rack 54 from slipping. The cooperation between the control rack 54 and the hook claws 33 improves the working reliability of the power assembly 5. A connecting rod 45 is slidably connected to a protrusion 51. The connecting rod 45 has a groove, allowing it to engage with the protrusion 51 at its upper limit position, thus enabling the connecting rod 45 to drive the protrusion 51 to move. A limit rod 511 is provided on the protrusion 51. The side of the limit rod 511 near the connecting rod 45 is made of flexible material. The limit rod 511 is detachably fixed to the connecting rod 45, allowing the stirring rod 42 to rotate to the limit rod 511, where the limit rod 511 deforms and is fixedly connected to the limit hole, thereby enhancing the control of the loading and unloading vehicle body 3. For the locking effect, the protrusion 51 is welded or keyed to a transmission rack 52, which in turn drives the transmission rack 52 to move. The transmission rack 52 meshes with an idler wheel 53, which in turn meshes with a control rack 54. The transmission rack 52 transmits power to the control rack 54 through the idler wheel 53. The teeth of the control rack 54 near the end of the box cover 1 are hook-shaped. The inner wall of the carriage is provided with a hook 541 to prevent the control rack 54 from slipping. One end of the transmission rack 52 is welded or threaded to a lever 55 for lifting the box cover 1. The end of the control rack 54 away from the lever 55 is welded to a rocker arm 56 for controlling the operation of the locking assembly 6. The side of the rocker arm 56 near the control rack 54 is kept horizontal with the connecting rod 45. The rocker arm 56 controls the movement of the locking assembly 6 as the connecting rod 45 rotates.

[0036] like Figures 6 to 9 As shown, a control rod 61 is fixedly connected to the side of the rocker arm 56 away from the control rack 54, thereby enabling the control rod 61 to control the operation of the clamping assembly. A cam disk 62 is fixedly connected to the control rod 61, and a spherical block 611 is provided on the control rod 61. The spherical block 611 is on the same plane as the main shaft 41, thereby enabling the control rod 61 to be slidably connected to a locking pawl 64. The locking pawl 64 has a deformable part 641 on the side near the limiting disk 63. The deformable part 641 is slidably connected to the connecting rod 45. The deformable part 641 is made of rubber, thereby improving the locking effect of the locking pawl 64. During the operation of the cement loading and unloading truck, the deformable part 641 can clean the limiting disk 63. At the same time, some cement will adhere to the deformable part 641, increasing the hardness and usability of the deformable part 641. The life-sustaining locking pawl 64 contacts the limiting plate 63, thereby enabling the control rod 61 to drive the locking pawl 64 to work. The locking pawl 64 contacts the limiting plate 63, and the limiting plate 63 contacts the drive wheel, thereby enabling the drive wheel to be clamped by the limiting plate 63. A locking hole 651 is provided in the limiting frame 65. The axis of the locking hole 651 is corrugated. The locking hole 651 is slidably connected to the connecting rod 45. The connection point between the locking hole 651 and the connecting rod 45 is located at the maximum curvature of the locking hole 651, thereby enabling the locking hole 651 to automatically lock the connecting rod 45. Since the connecting rod 45 will naturally slide down after being inserted into the locking hole 651, it will be clamped by the locking hole 651 when it slides down to the maximum curvature of the locking hole 651, thereby preventing the connecting rod 45 from falling off.

[0037] During the movement of the cement loading and unloading truck, the drive motor 2 starts and drives the main shaft 41 to move. The main shaft 41 drives the rotating bushing to move in a circular motion around the axis of the main shaft 41 and to move horizontally along the axis of the main shaft 41. At the same time, the main shaft 41 drives the stirring rod 42 to rotate, stirring the cement in the loading and unloading truck body 3. The rotating bushing drives the moving bushing 44 to move in a circular motion around the axis of the main shaft 41 and to move horizontally along the axis of the main shaft 41. Therefore, the connecting rod 45 stirs the cement in the truck body 32, and the stirring direction is different from that of the stirring rod 42. When the moving bushing 44 does not rotate but only moves horizontally, the connecting rod 45 is connected to the power component 5, driving the power component 5 to move horizontally. When the cement loading and unloading truck needs to be fed, the connecting rod 45 drives the protrusion 51 to move, which in turn drives the rack 52 to move closer to the box cover 1. The paddle 55 lifts the box cover 1, and the cement... The cement is poured into the truck body 32, and at the same time, the rack 54 is controlled to move away from the cover 1, which in turn drives the swing arm 56 to move. The swing arm 56 drives the control rod 61 to rotate by pushing the spherical block 611. When the control rod 61 rotates, the cam disk 62 and the limit frame 65 are relatively displaced, which causes the limit clamp 65 to deflect. The limit frame 65 drives the locking pawl 64 to deflect synchronously. The deformed part 641 of the locking pawl 64 contacts the limit disk 63, thereby locking the wheel and preventing the loading and unloading vehicle body from moving, which would cause the cement to spill out when it is loaded into the loading and unloading vehicle body 3. When the feeding ends, the transmission rack 52 moves away from the cover 1, thereby achieving a clearance fit between the cover 1 and the truck body 32 to prevent cement from splashing out. At the same time, the rack 54 is controlled to move closer to the cover 1, which in turn drives the swing arm 56 to control the deformed part 641 to release the wheel.

[0038] Although the beneficial effects of the present invention have been shown in detail and embodiments have been provided in this specification, those skilled in the art can make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
