[0002] Imitation stone curbstones are similar in appearance to natural stone, and the color and texture can be selected according to needs to meet the needs of different scenarios. They have excellent pressure resistance and durability. In addition, they are waterproof, stain-proof and corrosion-resistant, ensuring that they can be used for a long time in various complex climate and environmental conditions.

[0003] In the prior art, for example, a Chinese utility model patent with announcement number CN216661270U discloses a transmission device for imitation stone curbstones, which supports a placement plate by means of support rollers. When transmission is required, a driving assembly is used to drive the transmission roller to rotate, so that the transmission protrusion acts on the contact protrusion on the bottom surface of the placement plate during the rotation process, thereby driving the placement plate to move on the support roller to achieve transmission.

[0004] However, in the above-mentioned device, since the transmission protrusion is arranged on the transmission roller rotating around its own axis, the effective range of the transmission protrusion is limited. Therefore, in the entire transmission device, multiple transmission rollers need to be arranged along the transmission direction, and two adjacent transmission rollers need to be kept close to each other to ensure that the transmission protrusions on the two adjacent transmission rollers can act on the contact protrusions on the placement plate in succession. Therefore, in the entire transmission device, multiple transmission rollers need to be arranged, resulting in the transmission device as a whole requiring multiple parts, complex structure, increased cost, and since the driving component drives the multiple transmission rollers and the transmission protrusions on the transmission rollers to rotate, energy consumption is increased.

DETAILED DESCRIPTION

[0033] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0034] First embodiment

[0035] like Figure 1-Figure 10 As shown, the conveyor of the imitation stone curbstone of the first embodiment of the utility model comprises:

[0036] A support assembly 1, the top surface of the support assembly 1 extends along a first horizontal direction, and a storage rack 2 is arranged on the top surface, and the storage rack 2 is used to place an imitation stone curbstone 3;

[0037] The propulsion assembly 4 includes a driving sprocket 41, a driven sprocket 42, a chain 43, a driving unit 44 and a propulsion unit 45. The chain 43 is arranged on one side of the support assembly 1. The chain 43 is oval in shape and the length direction is parallel to the first direction. The driving sprocket 41 is connected to the driven sprocket 42 through the chain 43. The driving unit 44 drives the driving sprocket 41 to rotate around its own axis. The propulsion unit 45 is distributed on the outer periphery of the chain 43 along the circumference of the chain 43. The activity trajectory of the propulsion unit 45 intersects with the storage rack 2 and is separated from the support assembly 1.

[0038] When the conveyor is in use, the storage rack 2 is placed on the top surface of the support assembly 1, and a number of imitation stone curbstones 3 are placed on the storage rack 2. The storage rack 2 is supported by the support assembly 1, and then the driving unit 44 is started to make the active sprocket 41 rotate around its own axis. Through the transmission relationship between the active sprocket 41, the driven sprocket 42 and the chain 43, the chain 43 can rotate along its own circumference. During the rotation process, the chain 43 drives the propulsion unit 45 to move. Since the moving trajectory of the propulsion unit 45 intersects with the storage rack 2 and is separated from the support assembly 1, the propulsion unit 45 can avoid the support assembly 1 and contact the storage rack 2 during the movement, thereby acting on the storage rack 2, driving the storage rack 2 to translate under the support of the support assembly 1. In this device, the storage rack 2 can be driven to move by only a single propulsion unit 45 on the chain 43 acting on the storage rack 2, and there is no need to set up multiple transmission rollers and rely on multiple transmission rollers to act on the storage rack 2 in turn to move the storage rack 2. Therefore, the conveyor structure of this embodiment is simpler, which can effectively reduce costs, and only a single propulsion unit 45 is required to drive the storage rack 2 and the imitation stone curb 3 on the storage rack 2 to move, thereby effectively saving energy consumption.

[0039] A further improvement is that the top surface of the support assembly 1 is located above and to the side of the chain 43, and the propulsion unit 45 connected to the upper layer of the chain 43 is arranged between the horizontal plane where the top of the storage rack 2 is located and the horizontal plane where the bottom of the storage rack 2 is located.

[0040] Specifically, the support assembly 1 of this embodiment is provided with at least two, extending along the length direction of its top surface, and the specific structure of the support assembly 1 can refer to Figure 6-Figure 8 As shown, a rolling member protrudes from the top surface of the support assembly 1, and the rolling member is used to reduce the resistance on the bottom surface of the storage rack 2 when the propulsion unit 45 pushes the storage rack 2 to move; the rolling member is a ball 11, and the ball 11 is densely distributed on the top surface of the support assembly 1 and rotates in situ with its own sphere center as the center; the support assembly 1 includes a horizontal lower support plate 12 and a horizontal upper support plate 13 that is detachably arranged on the lower support plate 12, and the top surface of the lower support plate 12 is provided with a lower recess 121, and the lower support plate 12 is provided with an upper through hole 131, and the upper through hole 131 and the lower recess 121 enclose a receiving cavity for the ball 11 to rotate.

[0041] To be more specific, the upper support plate 13 and the lower support plate 12 are both horizontal rectangular plates, and the four corners of the upper support plate 13 are fixedly connected to the four corners of the lower support plate 12 by four pairs of threaded bolts 16 and nuts 17, and the bottom surface of the upper support plate 13 is fixed with a support frame 14, and the support frame 14 is an inverted U-shape, and the top of the support frame 14 is penetrated through the inner side of the chain 43 so that the propulsion unit 45 can avoid the support assembly 1 when it moves, and the lower recess 121 and the upper through hole 131 are respectively distributed in a rectangular array on the lower support plate 12 and the upper support plate 13, wherein the lower recess 121 is hemispherical, and the plane where the inner wall of the upper through hole 131 is located is a spherical surface, and the inner diameter of the spherical surface is the same as that of the ball 1 1 and the inner diameter of the lower recess 121 are consistent, and the lower recess 121 corresponds to the upper through hole 131 one by one, and the thickness of the upper support plate 13 is smaller than the radius of the ball 11, so that the lower recess 121 and the upper through hole 131 are enclosed to form a accommodating cavity for the ball 11 to rotate, and the top of the ball 11 protrudes from the top surface of the upper support plate 13. When the storage rack 2 is placed on the support assembly 1, there is a gap between the storage rack 2 and the top surface of the upper support plate 13, and the bottom of the storage rack 2 is supported by the top of the ball 11, and the ball 11 rotates in situ around its own spherical center, thereby reducing the resistance encountered by the storage rack 2 when the propulsion unit 45 pushes the storage rack 2 to move, thereby reducing the power consumption of the device.

[0042] The specific structure of the storage rack 2 in this embodiment is as follows Fig. 9 and Fig.10 As shown, the storage rack 2 includes a rectangular plate-shaped placement plate 21, the top surface of which is used to place the imitation stone curbstone 3, and near the circumferential outer edge, there are positioning holes 211 distributed along the circumference of the placement plate 21, and the top surface of the placement plate 21 is provided with a circumferentially arranged baffle plate 22, and the bottom of the baffle plate 22 is integrally connected with a latch 221, and the latch 221 is plugged and matched with the positioning hole 211. In this way, when the storage rack 2 is used, the latch 221 is inserted into the positioning hole 211, so that the baffle plate 22 is distributed along the circumference of the placement plate 21, and the imitation stone curbstone 3 is placed between the baffle plate 22 and the placement plate 21, which can prevent the imitation stone curbstone 3 from detaching from the placement plate 21; after the storage rack 2 is used, it is convenient to remove the baffle plate 22 from the placement plate 21, and the baffle plate 22 and the placement plate 21 are stacked for storage, thereby reducing the storage space occupied.

[0043] A further improvement is that two chains 43 are provided, which are arranged on both sides of the support assembly 1 , and the propulsion unit 45 is detachably arranged between the two chains 43 .

[0044] After adopting the above-mentioned improvement, the two chains 43 act on two places of the propulsion unit 45 respectively and simultaneously, driving the propulsion unit 45 to move smoothly, so that after the propulsion unit 45 acts on the storage rack 2, it can drive the storage rack 2 to move stably. Moreover, the propulsion unit 45 can be detachably arranged between the two chains 43, so as to facilitate the adjustment of the distance between two adjacent propulsion units 45 along the circumference of the chain 43 according to the size of the storage rack 2, so that the conveyor can transport two or more storage racks 2 at the same time.

[0045] Specifically, the driving sprockets 41 corresponding to the two chains 43 and the corresponding driven sprockets 42 are fixedly connected by two concentric shafts 46, and bearings 47 are provided at the ends of the concentric shafts 46. The inner ring of the bearing 47 is fixedly connected to the concentric shaft 46, and the inner ring is fixedly connected to the support frame 14. The driving unit 44 includes a driving motor, and the casing of the driving motor is fixedly connected to the support frame 14. The output shaft is fixedly connected to the coaxial centerline of the concentric shaft 46 corresponding to the driving sprocket 41.

[0046] A further improvement is, Figure 3-Figure 5 As shown, both chains 43 are provided with sockets 431 distributed along their own circumferences, and the propulsion unit 45 includes a propulsion rod 451 extending along the distribution direction of the two chains 43 and a plug 452 detachably arranged at both ends of the propulsion rod 451, the plug 452 is plugged into and matched with the socket 431 and is connected to a limit plate 453, and the limit plate 453 is arranged on the side of the chain 43 away from the propulsion rod 451; the plug 452 is threadedly connected to the propulsion rod 451.

[0047] The above structure facilitates the detachable connection between the propulsion unit 45 and the two chains 43. Specifically, during installation, the propulsion rod 451 is placed between the two chains 43 and the two ends of the propulsion rod 451 are aligned with the insertion holes 431 somewhere on the two chains 43. The insertion tube 452 is inserted into the insertion hole 431. The insertion hole 431 is a round hole, and the inner diameter is consistent with the outer diameter of the insertion tube 452, which facilitates the rotation of the insertion tube 452 to achieve a threaded connection with the end of the propulsion rod 451 until the insertion tube 431 is inserted. The limit plate 453 on 52 abuts against the chain 43 to realize the installation of the propulsion unit 45 on the chain 43. After the chain 43 rotates, the propulsion rod 451 is driven to move, and the propulsion rod 451 is used to contact one side of the placement plate 21, thereby driving the storage rack 2 and the imitation stone curbstone 3 in the storage rack 2 to move; when disassembling, the insert tube 452 is unscrewed from the end of the propulsion rod 451, and the insert tube 452 is separated from the socket 431, thereby completing the separation of the propulsion unit 45 and the chain 43.

[0048] Second embodiment

[0049] like Fig.11 and Fig.12As shown, the conveyor for imitation stone curbstones of the second embodiment of the utility model is based on the first embodiment, with the difference that the support assembly 1 further includes two guide units 15 arranged opposite to each other, and the storage rack 2 is attached to the two guide units 15 .

[0050] The guide unit 15 can prevent the storage rack 2 from being displaced in the width direction of the upper support plate 13 when moving on the support assembly 1. In this way, the chain 43 drives the propulsion unit 45 to act on the storage rack 2, thereby ensuring stable movement of the storage rack 2.

[0051] A further improvement is that the two guide units 15 each include a guide wheel 151 that rotates around its own axis, the axis of the guide wheel 151 extends in the vertical direction, and the guide wheel 151 is connected to a telescopic unit 152 that drives itself to move parallel to the top surface of the support assembly 1.

[0052] Specifically, the guide unit 15 also includes an L-shaped guide frame 153, which includes a horizontal plate and a vertical plate that are integrally connected. The horizontal plate is fixed above the support frame 14. The telescopic unit 152 is a telescopic cylinder whose axial direction is parallel to the distribution direction of the two chains 43. The cylinder barrel is fixed on the vertical plate, and the piston rod is passed through the inner side of the vertical plate and is connected to the guide wheel 151.

[0053] The position of the guide wheel 151 can be conveniently adjusted by the telescopic cylinder, thereby conveniently adjusting the distance between the two opposite guide units 15 according to the width size of the storage rack 2 to adapt to the storage rack 2, making it convenient for the storage rack 2 to stably pass through the two guide units 15 and avoiding position displacement of the storage rack 2 in the width direction of the upper support plate 13.

[0054] 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 technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
