[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] Example 1

[0039] Please combine Figures 1 to 11 , a processing system for concrete cable trench cover, comprising a frame (not shown), a barrel 1, and a transmission device 2. In this embodiment, the barrel 1 is a cylindrical structure with a hollow structure inside. Concrete to be poured is input into the barrel 1, and the barrel 1 has a feed port (not shown) for inputting concrete.

[0040] The barrel 1 is installed upright on the frame, and has a discharge port (not shown) at the bottom of the barrel 1. A discharge valve 28 is installed at the discharge port to release the concrete in the barrel 1 to be injected into the precast cover plate mold 3 when the precast cover plate mold 3 is transported below it.

[0041] The transmission device 2 is horizontally installed at the bottom of the frame, and is used to transmit the prefabricated cover plate mold 3 to the bottom of the barrel 1, so that concrete can be injected into the prefabricated cover plate mold 3 through the discharge port. The transmission device 2 in this embodiment can be a belt roller conveyor belt.

[0042] The barrel 1 is provided with a mixing device to make the concrete material input into the barrel 1 evenly distributed. The mixing device includes a drive shaft 4, a stirring paddle 5, and a scraping device. The drive shaft 4 is rotatably inserted into the barrel 1, the stirring paddle 5 is fixed to the bottom end of the drive shaft 4, and the scraping device is located above the stirring paddle 5 and is driven by the drive shaft 4 to scrape off the concrete attached to the inner wall of the barrel 1. The concrete is evenly mixed by the stirring paddle 5, and the scraping device is used to scrape off the material attached to a part of the inner wall of the barrel 1, thereby reducing the amount of material attached and improving the concrete utilization rate.

[0043] In this embodiment, a driving motor 26 is installed on the top of the barrel 1, and the output shaft of the driving motor 26 penetrates into the barrel 1 and is fixedly connected to the top of the driving shaft 4, so that the output shaft of the driving motor 26 can drive the driving shaft 4 to rotate.

[0044] In order to improve the feeding efficiency of the barrel 1, a slope (not shown) concave toward the center is provided at the bottom of the barrel 1 in this embodiment, so that the mixed concrete can quickly flow to the lower feeding port. A feeding channel (not shown) connected to the feeding port is formed in the middle of the slope, and a feeding auger 27 extending into the feeding channel is installed at the bottom of the stirring paddle 5. When the feeding auger 27 is driven to rotate by the driving shaft 4, the concrete can be accelerated to flow to the lower feeding port, thereby improving the grouting efficiency of the prefabricated cover plate mold 3.

[0045] The scraper device includes at least two cross arms 10 and a traction mechanism. At least two cross arms 10 are radially and evenly spaced around the outside of the drive shaft 4, that is, the centrifugal ends of at least two cross arms 10 are close to the inner wall of the barrel 1, and the centripetal ends converge on the outer peripheral side of the drive shaft 4, and the movements of each cross arm 10 are synchronized.

[0046] A first scraper 13 capable of contacting the inner wall of the barrel 1 is installed at the centrifugal end of each cross arm 10. The scraping surface of the first scraper 13 can be made of a flexible material, while the non-scraping surface is made of a hard material, which is convenient for disassembly, maintenance and installation stability. The scraping surface of the first scraper 13 can be designed to be an arc-shaped structure that matches the inner wall of the barrel 1 to improve its fit with the inner wall of the barrel 1, so that the scraping surface of the first scraper 13 has a larger scraping material coverage area.

[0047] In this embodiment 1, it is specified that the scraping surface of the first scraper 13 is always in contact with the inner wall of the barrel 1. The traction mechanism is suspended above the cross arm 10, and is used to traction the cross arm 10 to reciprocate in the axial direction of the drive shaft 4, and can drive the first scraper 13 to scrape up and down relative to the inner wall of the barrel 1 to achieve effective cleaning.

[0048] The traction mechanism includes a column 6, which is located above the cross arm 10. A through hole (not shown) is coaxially provided on the column 6, and the drive shaft 4 is inserted through the through hole. A wave-shaped and continuous track groove 7 is provided on the inner side wall of the through hole, and a pin 8 is fixed on the outer side wall of the drive shaft 4 to slide and engage with the track groove 7. At least two circumferentially equally spaced limit rods 14 are inserted into the column 6 for axial sliding. The number of limit rods 14 is consistent with the number of cross arms 10, and they correspond one to one. The top of each limit rod 14 is fixedly connected to the inner top wall of the barrel 1, and the bottom is movably inserted through the corresponding centripetal end of the cross arm 10. Each cross arm 10 is fixedly connected to the column 6 through a suspension rod 9. A limit hole (not shown) is provided on the column 6 for the limit rod 14 to slide through.

[0049] A suspension arm 11 is fixed to the bottom of the cross arm 10 near the centrifugal end, a connecting rod 12 is inserted into the centrifugal side of the suspension arm 11, and the centrifugal end of the connecting rod 12 is fixed to the centripetal side of the first scraper 13, thereby achieving synchronous movement of the cross arm 10, the connecting rod 12 and the first scraper 13.

[0050] In this embodiment, when the driving shaft 4 rotates, the ejector pin 8 can be driven to rotate synchronously in the circumferential direction, so that the ejector pin 8 continuously rubs and squeezes the groove wall of the wavy and continuous track groove 7, forcing the column 6 to reciprocate up and down in its axial direction under the limiting action of the limiting rod 14 to meet the movement of the ejector pin 8 in the track groove 7, so that the column 6 drives each cross arm 10 through the suspension rod 9, so that each cross arm 10 and the first scraper 13 thereon reciprocate up and down in the barrel 1, thereby effectively scraping off the material attached to the inner wall of the barrel 1.

[0051] Example 2

[0052] Please combine Figures 1 to 11 The difference between this embodiment and embodiment 1 is that, in this embodiment, it is provided that: the scraping surface of the first scraper 13 does not contact the inner wall of the barrel 1 when the first scraper 13 moves upward, but contacts the inner wall of the barrel 1 when the first scraper 13 moves downward, so that the inner wall of the barrel 1 is continuously scraped downward, so that the material body attached to the inner wall of the barrel 1 can be directly scraped to the bottom, and the utilization rate is better improved, which is specifically as follows:

[0053] The scraper device also includes a limit groove 24, a limit block 25 and an action mechanism. The limit groove 24 is fixed on the boom 11 and is parallel to the corresponding cross arm 10. The limit block 25 is slidably arranged in the limit groove 24. The connecting rod 12 is fixedly passed through the limit block 25, and a spring (not marked) is sleeved on the outside. The two ends of the spring are respectively fixed to the centrifugal side of the limit block 25 and the corresponding groove wall of the limit groove 24.

[0054] In this embodiment, initially, the cross arm 10 and the first scraper 13 are both located at the upper position in the barrel 1 (with a tendency to move downward), and at this time, when the spring is not deformed, the first scraper 13 does not contact the inner wall of the barrel 1. The action mechanism is arranged on the cross arm 10, and is used to drive the connecting rod 12 to perform centrifugal motion when the cross arm 10 moves downward, and to drive the centrifugal end of the connecting rod 12 to perform centripetal motion when the cross arm 10 moves upward, so as to realize that the first scraper 13 continuously scrapes the inner wall of the barrel 1 downward.

[0055] The action mechanism includes an L-shaped rod 20, the bending part of the L-shaped rod 20 is rotatably arranged on the suspension arm 11. In this embodiment, a rotating shaft 21 is fixedly inserted at the bending part of the L-shaped rod 20 to rotate synchronously with the L-shaped rod 20. The rotating shaft 21 is rotatably inserted on the outer side wall of the suspension arm 11, so that the L-shaped rod 20 can rotate relative to the suspension arm 11.

[0056] The vertical section of the L-shaped rod body 20 is connected to the centripetal end of the connecting rod 12. The cross arm 10 is provided with a through hole (not shown) through which the limit rod 14 can pass. The cross arm 10 is rotatably connected with a roller 15. A part of the roller 15 extends into the through hole and contacts the outer wall of the limit rod 14. The cross arm 10 moves downward or upward relative to the limit rod 14 through its through hole, so that the limit rod 14 contacting the roller 15 can rotate clockwise or counterclockwise.

[0057] A toothless gear 16 is coaxially fixed on the roller 15, and it rotates synchronously with the roller 15. A transmission gear 17 that matches the toothless gear 16 is rotatably connected to the cross arm 10, and the transmission gear 17 can be a full-tooth gear. The transmission gear 17 can receive intermittent transmission from the toothless gear 16. A first wire wheel 18 is coaxially fixed on the transmission gear 17, and whenever the transmission gear 17 rotates, it can drive the first wire wheel 18 to rotate synchronously. A traction rope (not marked) in a tensioned state is arranged on the first wire wheel 18. The free end of the traction rope passes around the fixed pulley 19 and is bolted and fixed to the horizontal section of the L-shaped rod body 20. The rotation of the first wire wheel 18 can drive the L-shaped rod body 20 to deflect around its bend through the traction rope, thereby realizing the axial drive of the connecting rod 12.

[0058] A fixing block 22 is fixed to the eccentric end of the connecting rod 12, and a runway-shaped pin hole 23 is provided on the fixing block 22. One end of the vertical section of the L-shaped rod body 20 is inserted into the pin hole 23 through a pin shaft. The runway-shaped pin hole 23 can provide sufficient displacement space in the vertical direction for the rotation drive of the vertical section of the L-shaped rod body 20 to avoid interference, so that the driving of the vertical section of the L-shaped rod body 20 on the connecting rod 12 is only stably reflected in the axial direction of the connecting rod 12.

[0059] The transmission gear 17 and the first wire wheel 18 are sleeved and fixed on the same reel (not shown), and the reel is connected to the shaft hole reserved on the cross arm 10 through a coil spring. When the transmission gear 17 is not driven, the coil spring is in a non-deformed state. This makes the coil spring elastically deformed every time the transmission gear 17 rotates under the driving action of the toothless gear 16 (whether the first scraper 13 moves down and the toothless gear 16 rotates counterclockwise, or the first scraper 13 moves up and the toothless gear 16 rotates clockwise). The elastic deformation can help the toothless gear 16 to stop acting on the transmission gear 17, and help the transmission gear 17 and the first wire wheel 18 to quickly rotate to the initial position, so that the traction rope is always kept in a tensioned state.

[0060] In summary, the working mode of this embodiment is:

[0061] When the cross arm 10, the suspension arm 11, and the first scraper 13 move downward, the roller 15 contacts the limit rod 14 to rotate counterclockwise and drives the toothless gear 16 to intermittently drive the transmission gear 17 to rotate clockwise, so that the first wire wheel 18 intermittently realizes the traction rope to be pulled and wound. When the traction rope is wound, it will pull the L-shaped rod body 20 to deflect around the rotating shaft 21 to push the connecting rod 12 and the limit block 25 to move centrifugally (the spring in the limit groove 24 is gradually compressed during this process), so that the first scraper 13 moves to fit the inner wall of the barrel 1, and cooperates with the downward movement to realize the downward scraping of the material body attached to the inner wall of the barrel 1. During this period, when the toothless gear 16 rotates to disengage from the transmission gear 17, the coil spring drives the transmission gear 17 and the first wire wheel 18 to rotate quickly to the initial position, so that the originally wound part of the traction rope is released from the first wire wheel 18, and the spring elastic force in the limit groove 24 is released to push the limit block 25, the connecting rod 12, and the first scraper 13 to disengage from the centripetal movement, so that the first scraper 13 temporarily detaches from the inner wall of the barrel, and the connecting rod 12 causes the L-shaped rod body 20 to rotate to the initial position, so that the traction rope remains in a tensioned state. As the toothless gear 16 rotates counterclockwise continuously during the downward movement of the cross arm 10, the first scraper 13 can be extended and retracted back and forth in the horizontal direction while moving downward, so that the scraping surface of the first scraper 13 can make rapid intermittent contact with the inner wall of the barrel 1. This action can not only scrape off the material attached to the inner wall of the barrel 1, but also use the scraping surface of the first scraper 13 to crush the larger material clumps protruding from the inner wall of the barrel 1, so that the first scraper 13 can effectively remove the material after the crushed material clumps are moved downward and pass through this position next time.

[0062] When the cross arm 10, the suspension arm 11, and the first scraper 13 move upward, the roller 15 contacts the limit rod 14 and rotates clockwise, driving the toothless gear 16 to intermittently drive the transmission gear 17 to rotate counterclockwise, so that the first wire wheel 18 intermittently releases the traction rope, which does not generate traction on the L-shaped rod 20, and the first scraper 13 never contacts the inner wall of the barrel 1, avoiding scraping the material above the inner wall of the barrel 1. During this period, whenever the toothless gear 16 rotates to disengage from the transmission gear 17, the coil spring drives the transmission gear 17 and the first wire wheel 18 to quickly rotate back to the initial position, so that the originally released part of the traction rope is rewound to the first wire wheel 18, so that the traction rope can always remain in a tensioned state, so as to effectively transmit the first scraper 13 when it moves downward again.

[0063] Example 3

[0064] Please combine Figures 1 to 11This embodiment 3 is an improved solution of embodiment 2. The bottom of the first scraper 13 has a material gathering surface 35 facing the center and tilted upward, so that when the first scraper 13 contacts the inner wall of the barrel 1 and moves downward, the scraped material moves along the material gathering surface 35 under the action of inertia, thereby effectively separating from the inner wall of the barrel 1 and falling to the bottom of the barrel 1, achieving effective scraping.

[0065] Furthermore, a mounting block 30 is fixed on the centrifugal side of the first scraper 13, and a slide groove 31 is provided on the mounting block 30. The extension direction of the slide groove 31 is parallel to the material guiding direction of the material gathering surface 35. A slider 32 is slidably connected in the slide groove 31, and a fixed transmission rod 33 is inserted through the slider 32. The transmission rod 33 is parallel to the material gathering surface 35 and the transmission rod 33 moves synchronously with the slider 32. A spring is also sleeved on the outside of the transmission rod 33, and the two ends of the spring are fixedly connected to one side of the slider 32 and the inner groove wall of the slide groove 31 respectively. When the first scraper 13 does not move and does not contact the inner wall of the barrel 1, and the spring does not deform, the second scraper 34 is located at the lower end of the material gathering surface 35, that is, the second scraper 34 is on the side of the material gathering surface 35 close to the inner wall of the barrel 1.

[0066] A second scraper 34 that fits the gathering surface 35 is fixed at one end of the transmission rod 33, and a pull rope (not shown) is bolted to the other end. A second wire wheel 29 is sleeved and fixed on the rotating shaft 21 at the bend of the L-shaped rod body 20, and the second wire wheel 29 rotates synchronously with the L-shaped rod body 20 and the rotating shaft 21, and the other end of the pull rope is wound around the second wire wheel 29.

[0067] The working mode of this embodiment is:

[0068] When the first scraper 13 moves downward and centrifugally, the L-shaped rod body 20 and the rotating shaft 21 drive the second wire wheel 29 to deflect synchronously, so that the second wire wheel 29 gradually reels the pull rope to pull the transmission rod 33, the slider 32, and the second scraper 34 toward the high end of the gathering surface 35 (this will cause the spring in the slide groove 31 to compress and deform). When the first scraper 13 moves downward and the first scraper 13 moves centripetally, the L-shaped rod body 20 and the rotating shaft 21 drive the second wire wheel 29 to return to its original position and rotate, so that the second wire wheel 29 releases the length of the pull rope that was originally wound up, and the spring force in the slide groove 31 releases to push the slider 32, the transmission rod 33 and the second scraper 34 to move toward the bottom of the material gathering surface 35, so that the material that has separated from the inner wall of the barrel 1 and gathered on the material gathering surface 35 can be pushed away from the material gathering surface and fall to the bottom of the barrel 1, so that the material scraped and collected on the material gathering surface 35 of the first scraper 13 can be quickly cleaned to the bottom of the barrel 1, so as to ensure the scraping and collecting effect of the first scraper 13 on the material on the inner wall of the barrel 1.

[0069] In summary, when the first scraper 13 moves downward and the first scraper 13 moves centrifugally, the second scraper 34 moves upward to make room for the material collected by the first scraper 13, and when the first scraper 13 moves centripetally, the second scraper 34 moves downward to quickly push the material collected on the first scraper 13 into the barrel 1, thereby ensuring the scraping and collecting effect of the first scraper 13 on the material on the inner wall of the barrel 1.

[0070] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
