Description
Technical Field
[0001] This invention relates to the field of drainage ditch construction equipment technology, and in particular to a sliding film machine for laying drainage ditch materials. Background Technology
[0002] When constructing drainage ditches, it is usually necessary to use a custom-made excavator to dig the trench, and then pour concrete into the trench. A slipform ditch machine can achieve one-time concrete pouring. Currently, when using a slipform ditch machine for concrete pouring, adding aggregate to the concrete provides higher stability and better durability than pure cement slurry; and aggregate is much cheaper than cement, serving as an inexpensive filler material for cement concrete, thus reducing concrete costs. Therefore, workers generally choose to use concrete containing aggregate. However, drainage ditches formed from aggregate concrete have a high aggregate content, resulting in many protrusions on the surface of the ditch, especially on the two sides, which not only affects aesthetics but also easily leads to the accumulation of debris.
[0003] Therefore, how to design a sliding film machine for laying ditch material on both sides of the ditch is the technical problem that this patent needs to solve. Summary of the Invention

[0008] Preferably, the device also includes a material-removing assembly for removing stones stuck on the hook claw. The material-removing assembly is disposed on an adjacent lower connecting plate. The material-removing assembly includes equally spaced fixing blocks, which are respectively fixed to the adjacent lower connecting plates.

The hook claw connected to the lower connecting plate is fixed to a rotating block, which is slidably connected to the anti-jamming frame.
[0009] Preferably, the system also includes a collection component for collecting stones. The collection component is mounted on the third support and includes a collection frame.

[0010] Preferably, the feeding assembly includes symmetrically arranged electric push rods, which are fixedly connected to the side of the collecting frame away from the second support. The collecting frame is symmetrically slidably connected to a lever, which is fixedly connected to the telescopic rod of the electric push rod.
[0011] Preferably, the assembly also includes a mixing component for agitating the concrete in the feeding hopper.

Detailed Implementation
[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1: A sliding film machine for drainage ditch fabric, referring to... Figures 1-4The system includes a concrete placing plate 1, a concrete funnel 101 fixedly connected to the top of the placing plate 1, a moving component for moving during concrete placement on the top of the placing plate 1, a second support 108 fixedly connected to the front side of the placing plate 1, second motors 109 symmetrically fixedly connected to the left and right sides of the second support 108, and rotating rods 110 symmetrically rotatably connected to the left and right sides of the second support 108. The symmetrically arranged rotating rods 110 are respectively fixedly connected to the output shafts of adjacent second motors 109. Upper connecting plates 111 are slidably connected to the rotating rods 110 at equal intervals. The lower connecting plate 1111, the upper connecting plate 111 and the lower connecting plate 1111 are all arranged vertically. The upper connecting plate 111 and the lower connecting plate 1111 are rotatably connected to the hooks 112. The upper connecting plate 111 and the lower connecting plate 1111 are each connected to the adjacent hooks 112 with a first torsion spring 113. The second bracket 108 is fixedly connected to the front side of the third bracket 117. The third bracket 117 is symmetrically fixedly connected to the left and right sides with guide plates 114. The guide plates 114 have guide grooves 116. The tops of the symmetrically arranged guide plates 114 are fixedly connected to the feeding funnels 115.
[0033] The moving component includes a track 107, which is set on the ground. A first motor 102 is fixed to the top of the fabric plate 1, and a first bracket 103 is fixed to the top of the fabric plate 1. The first bracket 103 is rotatably connected to a rotating shaft 105. A transmission belt 104 is wound around the rotating shaft 105 and the output shaft of the first motor 102 through a transmission wheel. Rollers 106 are symmetrically fixed to the left and right sides of the rotating shaft 105. The rollers 106 move horizontally along the adjacent track 107.
[0034] In use, the track 107 is installed on the ground near the trench, the placing plate 1 is placed in the trench, and the roller 106 is placed on the track 107. Concrete containing stones is added to the concrete funnel 101, and the concrete containing stones is poured into the trench to pour concrete. At the same time, the first motor 102 is started. The output shaft of the first motor 102 drives the rotating shaft 105 to rotate through the transmission wheel and the transmission belt 104. The rotating shaft 105 drives the roller 106 to rotate. The roller 106 moves on the track 107, so that the placing plate 1 moves in the trench. The material is placed and shaped by the moving placing plate 1.
[0035] The second motor 109 is started. The output shaft of the second motor 109 drives the rotating rod 110 to rotate. The rotating rod 110 drives the upper connecting plate 111 and the lower connecting plate 1111 to rotate. The upper connecting plate 111 and the lower connecting plate 1111 drive the hook 112 to rotate outward, so that the front end of the hook 112 inserts into the concrete containing stones on the inner wall of the trench. The second motor 109 is turned off. When the placing plate 1 moves along the trench, the placing plate 1 drives the second support 108 to move. The second support 108 drives the second motor 109, the rotating rod 110, the upper connecting plate 111, the lower connecting plate 1111, the hook 112 and the first torsion spring 113 to move. When the hook 112... When hook 112 catches a protruding stone in the concrete, the movement of hook 112 is resisted, causing hook 112 to rotate inward while moving. The first torsion spring 113 deforms. Since hook 112 catches a protruding stone in the concrete, as hook 112 moves and rotates inward, it can hook the protruding stone inward. The stone is hooked out and falls downward, detaching from hook 112. Then, under the action of the first torsion spring 113 resetting, it drives hook 112 to rotate outward and re-insert into the concrete containing the stone on the inner wall of the trench. In this way, the protruding stone in the concrete is removed by hook 112, avoiding the accumulation of debris caused by the protruding stone on the inner wall of the ditch.
[0036] Concrete is added into the feeding funnel 115, and the concrete funnel 101 discharges the concrete into the guide trough 116, thereby applying the concrete to the concrete containing stones, thus repairing the concrete surface containing stones and smoothing the two sides of the ditch.
[0037] After the trench is poured, turn off the first motor 102 and start the second motor 109. The output shaft of the second motor 109 drives the rotating rod 110 to reverse. The rotating rod 110 drives the upper connecting plate 111 and the lower connecting plate 1111 to reverse. The upper connecting plate 111 and the lower connecting plate 1111 drive the hook 112 to rotate inward and reset. Then, turn off the second motor 109.
[0038] Example 2: Based on Example 1, referring to... Figure 1 , Figure 5 and Figure 6 It also includes an adjustment component for adjusting the distance between the hooks 112. The adjustment component is set on the rotating rod 110. The adjustment component includes connecting blocks 201 arranged symmetrically on the left and right. The connecting blocks 201 arranged symmetrically on the left and right are respectively fixed to the upper part of the adjacent rotating rod 110. The connecting blocks 201 are rotatably connected to the adjustment handle 2. The upper connecting plate 111 and the adjacent lower connecting plate 1111 are threadedly connected to a two-way screw 202. The adjacent two-way screws 202 are fixed to each other. The upper two-way screw 202 is fixed to the adjustment handle 2.
[0039] To prevent stones from getting stuck between the hook claws 112, the double-acting screw 202 can be manually rotated forward and backward by adjusting the handle 2. The double-acting screw 202 drives the upper connecting plate 111 and the lower connecting plate 1111 on the same double-acting screw 202 to move towards or away from each other, thereby adjusting the distance between the hook claws 112. In this way, the distance between the hook claws 112 can be adjusted according to the size of the stones, thus preventing stones from getting stuck between the hook claws 112.
[0040] Reference Figure 1 , Figure 7 and Figure 8 It also includes a material-dispensing component for dispensing stones stuck on the hook 112. The material-dispensing component is disposed on the adjacent lower connecting plate 1111. The material-dispensing component includes equally spaced fixing blocks 3. The equally spaced fixing blocks 3 are respectively fixed to the adjacent lower connecting plate 1111. The equally spaced fixing blocks 3 are arranged vertically. The fixing blocks 3 are slidably connected to the anti-jamming bracket 302. The hook 112 connected to the lower connecting plate 1111 is fixedly connected to the rotating block 301. The rotating block 301 is slidably connected to the anti-jamming bracket 302.
[0041] When a stone gets stuck between the hook claws 112, as the hook claws 112 rotate inward, the hook claws 112 drive the anti-jamming bracket 302 to move outward through the rotating block 301. The anti-jamming bracket 302 then dislodges the stone stuck between the hook claws 112, preventing material jamming from affecting the work process.
[0042] When the hook 112 rotates outward to reset, the hook 112 drives the anti-jamming bracket 302 to move inward to reset via the rotating block 301.
[0043] Reference Figure 1 , Figure 9 and Figure 10 It also includes a collection component for collecting stones. The collection component is set on the third support 117. The collection component includes a collection frame 4, which is fixed to the top of the third support 117. The collection frame 4 is symmetrically rotatably connected to a one-way door 401. A second torsion spring 402 is symmetrically installed between the symmetrically arranged one-way door 401 and the collection frame 4. A pusher component for pushing stones into the collection frame 4 is provided on the front side of the collection frame 4.
[0044] The feeding assembly includes symmetrically arranged electric push rods 403, which are fixed to the front side of the collection frame 4. The collection frame 4 is symmetrically slidably connected to levers 404, which are fixed to the telescopic rods of the electric push rods 403.
[0045] To collect the stones, the electric push rod 403 is activated, and the telescopic rod of the electric push rod 403 is controlled to drive the lever 404 to move inward, thereby pushing the stones on the third support 117 to move inward. When the stones come into contact with the one-way door 401, the stones push the one-way door 401 to rotate inward and open, allowing the stones to enter the collection frame 4. Then, the telescopic rod of the electric push rod 403 is controlled to drive the lever 404 to move outward and reset. Then the electric push rod 403 is closed. In this way, stones are prevented from accumulating on the third support 117, affecting the operation of the hook 112, and preventing stones accumulated on the third support 117 from rolling onto the concrete at the bottom of the ditch, causing a large amount of stones to accumulate on the concrete at the bottom of the ditch.
[0046] Reference Figure 1 and Figure 11 It also includes a mixing assembly for agitating the concrete in the feeding hopper 115. The mixing assembly is located in the feeding hopper 115 and includes a third motor 5. The third motor 5 is fixedly connected to the right side of the feeding hopper 115. A spiral blade 501 is rotatably connected inside the feeding hopper 115. The spiral blade 501 is fixedly connected to the output shaft of the third motor 5.
[0047] To prevent the concrete in the feeding hopper 115 from solidifying, the third motor 5 is started. The output shaft of the third motor 5 drives the spiral blade 501 to rotate and mix the concrete in the feeding hopper 115, thus preventing the concrete in the feeding hopper 115 from solidifying. After the trench is poured, the third motor 5 is turned off.
[0048] Reference Figure 1 , Figure 12 , Figure 13 and Figure 14 It also includes an acceleration component for accelerating the flow of concrete. The acceleration component is set in the feeding funnel 115. The acceleration component includes a slide rail 6 arranged symmetrically on the left and right. The slide rail 6 is fixed to the bottom of the feeding funnel 115. The slide rail 6 is slidably connected to an acceleration frame 601. The acceleration frame 601 is toothed and is located in the guide trough 116. The spiral blade 501 is symmetrically fixed to a trigger block 602. The trigger block 602 contacts and cooperates with the adjacent acceleration frame 601. The bottom of the guide trough 116 is fixed to an inclined block 603. The bottom of the feeding funnel 115 is fixed to a guide block 604. The guide block 604 has symmetrical guide grooves. The guide grooves of the guide block 604 are arranged from narrow to wide from the inside to the outside.
[0049] To expedite the flow of concrete from the filling funnel 115 to the side of the repair ditch, when the spiral blade 501 rotates, it drives the trigger block 602 to rotate, which in turn drives the acceleration frame 601 to move upward. When the spiral blade 501 separates from the trigger block 602, the flowability of the concrete causes the acceleration frame 601 to move downward and reset. Thus, the contact and separation between the trigger block 602 and the acceleration frame 601 causes the acceleration frame 601 to move up and down repeatedly. Furthermore, since the acceleration frame 601 is toothed, it can accelerate the flow of concrete from the filling funnel 115 to the side of the repair ditch.
[0050] Because the guide channel of the guide block 604 is set from narrow to wide from the inside to the outside, the concrete in the material filling funnel 115 flows to the left and right, accelerating the outflow of concrete for repair.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
