[0040] The present invention will be further described below with reference to the accompanying drawings.

[0041] As attached Figures 1 to 12 A municipal curb automatic paving device as shown, Figure 1 , including a curbstone paving vehicle 6 that can move in a straight line along the edge 10 of a road 9, the curbstone paving vehicle 6 includes a carriage 5 and a storage platform 8, the storage platform 8 carries a stack 1a formed by stacking a plurality of curbstones 1; one side of the carriage 5 is connected to a lifting platform 3 that can be raised and lowered through a lifter 4, and a curbstone feeding arm 13 parallel to the road edge 10 is fixedly connected to the lifting platform 3. Figure 2 A curbstone conveying trough 2 is provided on the curbstone feeding arm 13, and the lower side of the end of the curbstone feeding arm 13 is connected to the laying unit 7. The lower part of the conveying end 2.1 of the curbstone conveying trough 2 is hollowed out, so that the curbstone blocks 1 reaching the conveying end 2.1 of the curbstone conveying trough 2 can be fed downward into the laying unit 7. The lower side of the laying unit 7 corresponds to the road edge 10. In the actual working environment, the upper surface of the road edge 10 is slightly lower than the surface of the road 9.

[0042] like Figure 4 A linear pusher 12 is provided at one end of the curbstone conveying trough 2 away from the conveying terminal 2.1. A push rod 61 of the linear pusher 12 can push the curbstone 1 in the curbstone conveying trough 2 toward the conveying terminal 2.1 of the curbstone conveying trough 2.

[0043] The lifting platform 3 is provided with a robotic arm that can transfer the curb stones 1 on the stacking pile 1a to the curb stone conveying trough 2. The robotic arm is an optional structure (not shown in the attached device). In the absence of the robotic arm, the process of transferring the curb stones 1 on the stacking pile 1a to the curb stone conveying trough 2 can be completed by the staff on the lifting platform 3.

[0044] like Figure 7 The paving unit 7 includes a semi-circular plate 16 with an opening facing downward, and a curb box 17 with an upper end opening is integrated on the lower side of the middle section of the semi-circular plate 16. The curb box 17 contains a curb storage bin 20 with an upper end opening. When the opening of the curb storage bin 20 faces upward, the upper end of the curb storage bin 20 is connected to the hollow bottom of the conveying terminal 2.1; a vertical b pusher 19 is fixedly installed on the bottom wall 17.1 of the curb box 17, and the upper end of the b push rod 55 of the b pusher 19 is fixedly connected to the push plate 54 in the curb storage bin 20; Figure 9 As shown in FIG. 2 , when the push rod 55 is extended, the push plate 54 rises to the hollow bottom of the transmission end 2.1; Figure 8 As shown, when the push rod b 55 is in the retracted state, the push plate 54 is at the bottom of the curb storage bin 20, and the bottom of the curb stone 1 contained in the curb storage bin 20 is supported by the push plate 54, and the upper part of the curb stone storage bin 20 containing a curb stone 1 forms a cement mortar filling pool 50 waiting to be filled with cement mortar.

[0045] like Figure 5 and 6 , the two sides of the curb box 17 are respectively fixedly connected with a rotating shaft 18 and a rotating shaft 21, and the rotating shaft 18 and the rotating shaft 21 are both coaxial with the semi-circular arc plate 16; the lower side of the curb feeding arm 13 is fixed with a bearing seat 26 and a bearing seat 27, and the rotating shaft 18 and the rotating shaft 21 are respectively rotatably matched with the bearing holes on the bearing seat 26 and the bearing seat 27 through bearings; a rotating sleeve 25 is rotatably installed on the outside of the rotating shaft 21 through a bearing, and a rocker arm 29 is fixedly connected to one side of the rotating sleeve 25, and an arc-shaped mortar constraint plate 22 is fixedly connected to the end of the rocker arm 29, and the inner diameter of the arc-shaped mortar constraint plate 22 is the same as the outer diameter of the semi-circular arc plate 16; Figure 7 and 8 When the clockwise inner wall of the arc-shaped mortar restraint plate 22 slides with the counterclockwise outer wall of the semicircular plate 16 , the clockwise end of the arc-shaped mortar restraint plate 22 is located directly below the curb box 17 .

[0046] like Figure 7 The clockwise end of the arc-shaped mortar restraint plate 22 is integrally provided with a wing plate 31 folded outward, an oscillator is provided on the wing plate 31, and a mortar feed trough 14 is formed between the wing plate 31 and the outer wall of the semicircular plate 16.

[0047] The laying unit 7 is provided with a cement mortar injection unit, such as Figure 7 The cement mortar injection unit includes a cement mortar storage device 28, and the cement mortar outlet 33 at the lower end of the cement mortar storage device 28 corresponds to the mortar feed trough 14 directly above; the cement mortar storage device 28 is fixed to one side of the curb feed arm 13 by a bracket.

[0048] On the basis of the arc-shaped mortar restraining plate 22 remaining in position, the semicircular plate 16 rotates 90° counterclockwise, as shown in FIG. Figure 10 , the opening of the curbstone accommodating bin 20 becomes to the left, and the cement mortar filling pool 50 changes from horizontal to vertical. The clockwise inner wall of the arc-shaped mortar restraining plate 22 does not completely block the opening on the left side of the curbstone accommodating bin 20, so that a mortar filling inlet 51 is formed between the upper end of the cement mortar filling pool 50 and the bottom of the mortar feeding trough 14. After the semi-circular plate 16 continues to rotate counterclockwise by 90°, the opening of the curbstone accommodating bin 20 becomes downward, and the counterclockwise inner wall of the arc-shaped mortar restraining plate 22 blocks the downward opening of the curbstone accommodating bin 20.

[0049] The transmission structure of this scheme is as follows: an inner ring gear 32 is fixed on one side of the curb box 17, and the inner ring gear 32 is coaxial with the semi-circular arc plate 16. The outer wall of the rotating sleeve 25 is fixedly mounted with an a motor 24, and the a gear 23 at the output end of the a motor 24 is engaged with the inner ring gear 32; an arc rack 30 is fixed on the rocker arm 29, which is coaxial with the arc-shaped mortar constraint plate 22, and a b motor 72 is fixedly mounted on one side of the b bearing seat 27 through a bracket, and the b gear 71 at the output end of the b motor 72 is engaged with the arc rack 30.

[0050] The working principle and working method of the curbstone laying vehicle 6 for laying a curbstone 1 are as follows:

[0051] Step 1: The curbstone paving vehicle 6 drives to the vicinity of the road edge 10 and positions the laying unit 7 of the curbstone paving vehicle 6 directly above the road edge 10 where the curbstone 1 has not yet been laid. The lifter 4 then drives the lifting platform 3 down until the counterclockwise outer arc surface of the arc-shaped mortar restraining plate 22 on the laying unit 7 is tangent to the road edge 10 where the curbstone 1 is to be laid.

[0052] In the initial state of the laying unit 7, the opening of the curb storage compartment 20 is facing upward, the push rod 55 is in the extended state, and the push plate 54 is at the hollow bottom of the conveying end 2.1. Figure 8 As shown;

[0053] Step 2: A worker or a robotic arm on the lifting platform 3 moves one or more curbstones 1 on the stack 1a to the curbstone conveying trough 2;

[0054] Step 3: The push rod 61 of the linear pusher 12 pushes the curbstone 1 in the curbstone conveying trough 2 toward the conveying end 2.1 of the curbstone conveying trough 2. The curbstone 1 that reaches the conveying end 2.1 is supported by the push plate 54 at the hollow bottom of the conveying end 2.1. Figure 8 As shown;

[0055] Step 4: Control the push rod 55 to retract downward, thereby driving the push plate 54 to descend to the bottom of the curb storage bin 20. The curb stone 1 at the conveying end 2.1 is lowered into the curb storage bin 20 along with the push plate 54 under the action of gravity. At this time, the upper part of the curb storage bin 20 containing the curb stone 1 forms a cement mortar filling pool 50 waiting to be filled with cement mortar. Figure 9 As shown;

[0056] In step five, the b motor 72 enters the braking state, so that the arc-shaped mortar constraint plate 22 enters the fixed state, and at the same time controls the a motor 24 to make the a gear 23 drive the semicircular arc plate 16 to rotate 90 degrees counterclockwise, thereby making the opening of the curb storage bin 20 turn to the left, and the cement mortar filling pool 50 changes from horizontal to vertical. The inner wall of the clockwise end of the arc-shaped mortar constraint plate 22 does not completely block the opening on the left side of the curb storage bin 20, so that a mortar filling inlet 51 is formed between the upper end of the cement mortar filling pool 50 and the bottom of the mortar feed trough 14. The cement mortar outlet 33 at the lower end of the cement mortar storage device 28 discharges the cement mortar into the mortar feed trough 14, and then the cement mortar reaching the mortar feed trough 14 is further poured into the cement mortar filling pool 50 through the mortar filling inlet 51 under the vibration of the oscillator, so that the cement mortar filling pool 50 is filled with cement mortar. Figure 10 As shown;

[0057] Step 6: Control the motor a 24 to make the gear a 23 drive the semicircular plate 16 to continue to rotate counterclockwise by 90 degrees. The opening of the curb storage bin 20 becomes downward. At this time, the counterclockwise inner wall of the arc-shaped mortar constraint plate 22 blocks the downward opening of the curb storage bin 20, and the cement mortar filling pool 50 filled with cement mortar is located at the lower part of the curb storage bin 20. Figure 11 As shown;

[0058] Step seven, control the b motor 72 to make the b gear 71 drive the arc rack 30, and then drive the arc-shaped mortar constraint plate 22 to rotate clockwise along the axis, so that the counterclockwise end of the arc-shaped mortar constraint plate 22 is separated from the downward opening of the curb storage bin 20. At this time, the curb stone 1 in the curb storage bin 20 pushes the cement mortar filled in the cement mortar filling tank 50 downward under the action of gravity and adheres it to the upper surface of the road edge 10, so that the lower surface of the curb stone 1 in the curb storage bin 20 adheres to the upper surface of the road edge 10 through the cement mortar filled in the cement mortar filling tank 50. At the same time, control the b push rod 55 downward to push the curb stone 1 downward through the push plate 54, so that the curb stone 1 is more tightly bonded to the road edge 10 through the cement mortar, thereby completing the paving of a curb stone 1. Figure 12 As shown;

[0059] Step eight: the lifter 4 drives the lifting platform 3 to rise, thereby driving the paving unit 7 to rise as a whole, so that the curb storage compartment 20 on the paving unit 7 rises to the point where it is separated from the curb 1 that has been adhered to the road edge 10;

[0060] Step nine, return to the state of "Step one", the curbstone paving vehicle 6 slowly moves forward along the path of the road edge 10, so that the laying unit 7 of the curbstone paving vehicle 6 corresponds to the other road edge 10 where no curbstone 1 is laid, and then refer to "Step two" to "Step eight" to complete the laying of the second curbstone 1.

[0061] It should be noted that, since this device does not have the function of filling the gap between two adjacent curb stones 1 that have been laid with cement mortar, the process of filling the gap between two adjacent curb stones 1 with cement mortar currently needs to be completed manually, or a corresponding filling device needs to be further developed.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
