When adjusting the height of the feeding cylinder of the existing device, the heights of each support rod need to be adjusted synchronously, which requires multiple people to operate simultaneously. The adjustment process is not only cumbersome, but also requires manual lifting of the feeding cylinder and support rods when adjusting the height, increasing the labor intensity of workers.

One side of the connecting piece is rotatably connected to a long support rod, and one side of the bottom end of the limit frame is rotatably connected to a short support rod. The connecting rod, long support rod and short support rod can be lifted by a hydraulic telescopic rod to adjust the height of the feeding mechanism. The adjustment process is simple and labor-saving, and can be completed by only one person. It is more simple and convenient to use. Moreover, the connecting piece is rotatably connected to the long support rod, so that the inclination angle of the feeding mechanism can be adjusted, improving the applicability of the feeding mechanism.

[0023] In this embodiment, the feeding port 104 is provided at one end of the feeding mechanism 101. The feeding port 104 is in a hopper shape and is used for inputting concrete raw materials into the feeding mechanism 101. The support frame mechanism 103 is installed at the bottom of the feeding mechanism 101. The support frame mechanism 103 includes limiting frames fixedly connected to both sides of the feeding mechanism 101. A connecting member is slidably connected inside the two limiting frames. One side of the connecting member is rotatably connected to a long support rod. One side of the bottom end of the limiting frame is rotatably connected to a short support rod. Limiting tubes are slidably sleeved outside the long support rod and the short support rod. The bottom of the limiting tube is fixedly installed on the moving and positioning mechanism. Connecting rods are fixedly connected to one side of the long support rod and the short support rod. A hydraulic telescopic rod is fixedly connected to the middle position at the bottom of the limiting tube. The hydraulic telescopic rod can lift the connecting rod, the long support rod and the short support rod to adjust the height of the feeding mechanism 101. The adjustment process is simple and convenient. Moreover, the connecting member is rotatably connected to the long support rod, so that the inclination angle of the feeding mechanism 101 can be adjusted, improving the applicability of the feeding mechanism 101. The mixing mechanism 102 includes two transmission discs connected by a transmission belt. One of the transmission discs is fixedly connected to the output end of the motor of the feeding mechanism 101. A mixing frame is fixedly connected to one side of the other transmission disc. A water leakage plate is fixedly connected to the discharge pipe of the feeding mechanism 101. One end of the water leakage plate is fixedly connected to a spherical member. One end of the spherical member is fixedly connected to a discharge port. A cap is threadedly connected to the outside of the discharge port. An annular member is fixedly connected to the outside of the water leakage plate. A water delivery pipe is fixedly connected to one side of the annular member. One end of the output pipe is fixedly connected to a water pump. The mixing frame is driven to rotate by the transmission disc, so that the materials can be preliminarily mixed and stirred while the feeding mechanism 101 is feeding, facilitating subsequent mixing processing. Water is added during mixing by the water pump, facilitating the control of the water content of the concrete and the addition of water to the internal part of the external mixing device, making the concrete preparation more convenient.

[0024] Among them, the bottom plate 105 is connected to the support frame mechanism 103 and is located at the lower end of the support frame mechanism 103. The connecting seat 106 is fixedly connected to the bottom plate 105 and is located at the bottom of the bottom plate 105. The connecting shaft 107 is rotatably connected to the connecting seat 106 and extends into the connecting seat 106. The moving wheel 108 is connected to the connecting shaft 107 and is located at the bottom of the connecting shaft 107. The pressing plate 109 is connected to the bottom plate 105 through the adjusting and positioning assembly and is located at the lower end of the bottom plate 105. The adjusting and positioning assembly is connected to the pressing plate 109 and drives the pressing plate 109 to move vertically. The number of the bottom plates 105 is two, which is matched with the number of the support frame mechanisms 103. The bottom plate 105 is of a cuboid structure, providing conditions for the connection between the moving and positioning mechanism and the support frame mechanism 103, and providing installation conditions for the connecting seat 106 and the adjusting and positioning assembly. The connecting seats 106 are provided at the four diagonal corners of the bottom of the bottom plate 105. The connecting seat 106 is of a cylindrical structure and is provided with a T-shaped groove with an open bottom, which is matched with the shape of the connecting shaft 107. The connecting shaft 107 is inserted and installed in the groove of each connecting seat 106. Through the cooperation of the groove of the connecting seat 106 and the connecting shaft 107, the rotational connection between the connecting seat 106 and the connecting shaft 107 is realized. The bottom of the connecting shaft 107 is fixedly connected to the top of the moving wheel 108. Through the connecting shaft 107, the rotational connection between the moving wheel 108 and the connecting shaft 107 is realized, making it easy for the moving wheel 108 to change direction. The moving wheel 108 is used to realize the moving work of the moving and positioning mechanism. Through the connecting seat 106, the connecting shaft 107 and the moving wheel 108, the universal rotational movement of the moving and positioning mechanism is realized. The pressing plates 109 are respectively provided at both ends of the bottom plate 105 close to the moving wheel 108. The pressing plate 109 is of a cuboid structure, and its length is matched with the width of the bottom plate 105. The pressing plate 109 is movably connected to the bottom plate 105 through the adjusting and positioning assembly. The pressing plates 109 respectively connected by a plurality of the adjusting and positioning assemblies are driven to move downward or upward at the lower end of the bottom plate 105. When the pressing plate 109 moves downward until it is in tight contact with the ground, the contact friction of the moving and positioning mechanism is increased, so that the moving wheel 108 cannot rotate and move, realizing the positioning and placement of the feeding equipment. When the pressing plate 109 moves upward so that the bottom of the pressing plate 109 is higher than the bottom end of the moving wheel 108, the pressing plate 109 is not in tight contact with the ground, enabling the moving wheel 108 to be pushed and rotated, so that the moving and positioning mechanism can drive the feeding equipment to move;Therefore, when it is necessary to move the feeding device for concrete mixing, the adjustment and positioning component drives the pressing plate 109 to rotate upward, so that the bottom position of the pressing plate 109 is at least higher than the bottom position of the moving wheel 108. Then, by pushing the feeding device, the support frame mechanism 103 is stressed, and the moving wheel 108 of the moving and positioning mechanism is stressed and rotates, driving the feeding device to move. Moreover, the device of the connecting seat 106 and the connecting shaft 107 facilitates the steering of the moving wheel 108, making the movement and steering of the feeding device convenient. When the feeding device moves to the designated position, the adjustment and positioning component drives the pressing plate 109 to move downward until the bottom of the pressing plate 109 abuts against the ground, and the moving wheel 108 cannot rotate and move due to the frictional force, realizing the fixed positioning work of the feeding device. Thus, the moving and positioning mechanism facilitates the movement and fixed positioning of the feeding device, realizes the convenient movement of the feeding device, and improves the applicability of the feeding device.

[0025] Secondly, the screw rod 110 is rotatably connected to the pressing plate 109 through a bearing, is located at the top of the pressing plate 109, and is threadedly connected to the bottom plate 105; the rotating member is connected to the screw rod 110 and drives the screw rod 110 to rotate; the limiting rod 111 is fixedly connected to the pressing plate 109 and is located at the top of the pressing plate 109. The threaded hole 114 is provided on one side of the bottom plate 105, penetrates through the bottom plate 105, and cooperates with the screw rod 110; the limiting hole 115 is provided on the side of the bottom plate 105 opposite to the threaded hole 114, penetrates through the bottom plate 105, and cooperates with the limiting rod 111. The threaded holes 114 are provided at both ends of one side of the two bottom plates 105, and the inner diameter of the thread of the threaded hole 114 matches the outer diameter of the thread of the screw rod 110 for the screw rod 110 to threadedly penetrate through the bottom plate 105. A bearing is provided at the bottom end of the screw rod 110 penetrating through the threaded hole 114 of the bottom plate 105, and is rotatably connected to one end of the top of the pressing plate 109 through the bearing. A pressing plate 109 is connected to the bottom of each screw rod 110, and a limiting rod 111 is fixedly provided at one end of each pressing plate 109 away from the screw rod 110. The limiting rod 111 is of an inverted L-shaped structure. The limiting rod 111 penetrates through the limiting hole 115 corresponding vertically on the bottom plate 105. The limiting hole 115 is in square cooperation with the bottom of the limiting rod 111 and penetrates through the bottom plate 105 for the fixed connection between the limiting rod 111 and the pressing plate 109. Moreover, the rotating member is installed at the top of the screw rod 110. By rotating the rotating member, the screw rod 110 is driven to move downward or upward in a threaded manner. Under the limitation of the rotation of the pressing plate 109 by the limiting rod 111, the pressing plate 109 is driven to move vertically up and down, so as to drive a plurality of pressing plates 109 to move and adjust respectively through the adjusting and positioning assembly, change the movement and positioning of the moving and positioning mechanism, and enable the height positions of the plurality of pressing plates 109 to be adjusted individually, so that even if the ground is not level, the feeding equipment of the concrete mixer can be kept horizontally placed.

[0026] Meanwhile, the turntable 112 is fixedly connected to the screw rod 110 and located at the top end of the screw rod 110; the rotating rod 113 is fixedly connected to the turntable 112 and located at the top of the turntable 112. The number of the turntables 112 matches the number of the screw rods 110. The turntable 112 has a circular structure. The middle position at the bottom of the turntable 112 is fixedly connected to the top of the screw rod 110, and the turntable 112 and the screw rod 110 are coaxial devices. The rotating rod 113 is fixedly arranged near the outer edge at the top of the turntable 112. The rotating rod 113 has a cylindrical structure. By manually rotating the rotating rod 113 clockwise, the rotating rod 113 drives the screw rod 110 to rotate downward. The screw rod 110 drives the pressing plate 109 to move downward under the rotational limit of the limiting rod 111. When the rotating rod 113 is rotated counterclockwise manually, the pressing plate 109 moves upward, so as to drive the pressing plate 109 to move up and down through the rotating member.

[0027] When using the feeding device for concrete mixing of the present utility model and it is necessary to move the feeding device for concrete mixing, the adjusting and positioning assembly drives the pressing plate 109 to rotate upward, so that the bottom position of the pressing plate 109 is at least higher than the bottom position of the moving wheel 108. Then, by pushing the feeding device, the support frame mechanism 103 is stressed, and the moving wheel 108 of the moving positioning mechanism is stressed and rotates, driving the feeding device to move. The connection seat 106 and the connecting shaft 107 facilitate the steering of the moving wheel 108, making the movement and steering of the feeding device convenient. When the feeding device moves to the designated position, the adjusting and positioning assembly drives the pressing plate 109 to move downward until the bottom of the pressing plate 109 abuts against the ground. Due to the frictional force, the moving wheel 108 cannot rotate and move anymore, realizing the fixed positioning work of the feeding device. Thus, the moving and fixed positioning of the feeding device are facilitated through the moving positioning mechanism, realizing the convenient movement of the feeding device and improving the applicability of the feeding device.

[0030] In this embodiment, the friction pad 216 is fixedly connected to the abutting plate 109 and is located at the bottom of the abutting plate 109. The shape of the friction pad 216 matches the rectangular shape of the bottom of the abutting plate 109. The number of the friction pads 216 is two, which are respectively fixedly installed at the bottoms of the two abutting plates 109. The friction pad 216 is made of rubber material, having a certain buffering function and used to increase the contact friction with the ground in contact, so that the abutting stability of the abutting plate 109 with the ground is better, and the positioning fixity of the mobile positioning mechanism is better.
