Description

Technical Field

[0001] This invention relates to the field of grilles, and more particularly to a split-type rotary mechanical grille. Background Technology

[0002] Rotary bar screens are used to intercept and lift floating garbage in water. However, in actual use, the drive component drives the ring chain to rotate. Due to the presence of floating garbage or slag, damage may occur. Therefore, the entire equipment needs to be lifted out for maintenance. The bar screen cannot filter properly, and at this time, floating garbage or slag cannot be blocked.

[0003] Chinese patent number "CN216703595U" discloses "a liftable rotary bar screen". The first bar screen unit in this patent is set in the guide rail and can be lifted. It is a split structure, which gives a way to set the bar screen and the frame separately. However, in this patent, the first bar screen unit slides in the guide rail. Since rotary bar screens are generally used to intercept and lift floating garbage in water, the guide rail is easily blocked by floating garbage, which will cause the first bar screen to be unable to slide later. Summary of the Invention

[0004] The purpose of this invention is to provide a split-type rotary mechanical grille.

[0005] The innovation of this invention lies in the hinge structure of the rotating rod engaging the rotating notch, which allows the frame to rotate relative to the grid plate. The weight of the frame presses the grid frame and the grid together. The figure-eight shaped limiting strip and locking strip ensure that the frame and the grid plate are perfectly aligned, without affecting the later insertion of the target teeth into the grid plate and the sliding motion between the grid bars to carry out the slag and floating waste.

[0006] To achieve the above-mentioned objectives, the technical solution of this invention is as follows:

[0007] A split-type rotary bar includes a frame with two parallel annular chains on the frame. Several sets of target teeth are arranged on the two parallel annular chains, with each end of a target tooth located on one of the two annular chains and driven to rotate by them. A drive assembly for rotating the annular chains is provided on the frame. A bar plate is provided on the backwater side of the frame, with several vertically arranged bar strips on the bar plate. Two swivel plates are provided on the bar plate, each with a swivel notch. Rotating rods for engaging the swivel notches are provided on both sides of the frame. Two limiting strips are provided on the frame along its length. Two locking strips are provided on the bar plate along its length. The outer surfaces of the cross-sections of the two limiting strips form a figure-eight shape. The inner surfaces of the cross-sections of the locking strips also form a figure-eight shape that engages with the outer surfaces of the limiting strips.

[0008] Furthermore, the screw-in notch is an flared notch. The rotating rod is easily inserted into the screw-in notch.

[0009] Furthermore, the drive assembly is a hand-cranked drive assembly; the hand-cranked drive assembly includes a drive shaft, a sprocket located at one end of the drive shaft, and a gearbox meshing with the sprocket.

[0010] Furthermore, the gearbox is equipped with a ratchet and pawl structure to prevent the target gear assembly from reversing.

[0011] Furthermore, the frame is divided into upper and lower sections, which are connected by two or more sets of adjusting components that can adjust the distance between the two sections. Since the equipment uses gear transmission, the gears must mesh to transmit power. However, the output gear is directly connected to the sprocket drive input shaft, and adjusting the sprocket input shaft to tension the chain requires adjusting the gearbox as well. This is inconvenient. Therefore, a split structure is adopted, where adjusting the tightening length of the bolts moves the upper section to achieve chain tension.

[0012] Furthermore, the adjustment assembly includes connecting blocks connected to the upper and lower sections respectively, wherein a screw is connected to one connecting block and a through hole is provided on the other connecting block through which the screw passes. After the screw passes through the through hole, it is limited by nuts screwed onto the screw and located on both sides of the through hole.

[0013] Furthermore, the target tooth assembly includes a target tooth rod and several parallel V-shaped target tooth plates located on the target tooth rod. When the target tooth assembly rotates to the grid plate, the V-shape of the V-shaped target tooth plates faces upwards. This facilitates lifting and removing the waste upwards.

[0014] Furthermore, reinforcing ribs are provided between the V-shaped target teeth, and these ribs are located on the side plates where the V-shaped target teeth are inserted into the grid plate, with a distance between the reinforcing ribs and the free ends of the side plates of the V-shaped target teeth. The use of reinforcing ribs strengthens the target tooth assembly and ensures consistent spacing between the V-shaped target teeth, allowing each V-shaped target tooth to be precisely inserted between the grid bars.

[0015] Furthermore, the annular chain includes several link groups. When the link groups are connected, a connecting shaft passes through two lower connecting plates, ball bearings, and two upper connecting plates. One end of the connecting shaft is limited by an end cap, and the other end has a insertion hole. A limiting member is inserted into the insertion hole. After the limiting member is bent and inserted into the insertion hole, its two free ends open, facilitating disassembly and replacement.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, the hinge structure of the rotating rod engaging the rotating notch allows the frame to rotate relative to the grid plate. The weight of the frame presses the grid frame and the grid together. The figure-eight structure of the limiting strip and the locking strip ensures that the frame and the grid plate are completely aligned. This does not affect the later insertion of the target teeth of the target tooth group into the grid plate and the sliding motion between the grid bars to carry out the slag and floating garbage.

[0018] 2. The present invention can adapt to areas without power supply by setting a manual driving mode.

[0019] 3. In this invention, a ratchet and pawl structure is used to prevent the ring chain and target tooth assembly from reversing.

[0020] 4. In this invention, since the equipment uses gear transmission, the gears must mesh with each other to transmit power. The output gear is directly connected to the sprocket transmission input shaft. Adjusting the sprocket input shaft to tension the chain must be done together with the gearbox. The machine head adopts a split structure. By adjusting the length of the bolt tightening, the machine head is moved to achieve the tensioning of the ring chain. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0029] Example 1: As Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, a split-type rotary grid includes a frame 1. The frame 1 has two parallel annular chains 2. Several sets of target teeth 3 are arranged on the two parallel annular chains 2. The two ends of each target tooth set 3 are located on the two annular chains 2 and are driven to rotate by the two annular chains 2. The annular chains 2 include several link groups. When the link groups are connected, a connecting shaft 2.1 passes through two lower connecting plates 2.2, ball bearings 2.3, and two upper connecting plates 2.4. One end of the connecting shaft 2.1 is limited by an end cap, and the other end has an insertion hole 2.11. A limiting member 2.12 is inserted into the insertion hole 2.11. After the limiting member 2.12 is bent and inserted into the insertion hole 2.11, the two free ends of the limiting member 2.12 open.

[0030] The frame 1 is equipped with a drive assembly 4 that drives the ring chain 2 to rotate. A grid plate 5 is provided on the back side of the frame 1. The grid plate 5 is provided with several vertically arranged grid bars 6. The grid plate 5 is provided with two swivel plates 7. The swivel plates 7 are provided with swivel notches 7.1. The swivel notches 7.1 are flared notches. Rotating rods 8 are provided on both sides of the frame 1 for engaging the swivel notches 7.1.

[0031] The frame 1 is provided with two limiting strips 1.1 arranged along the length of the frame 1, and the grid plate 5 is provided with two locking strips 5.1 arranged along the length of the grid plate 5. The outer side of the cross-section of the two limiting strips 1.1 forms a figure-eight structure; the inner side of the cross-section of the locking strip 5.1 is a figure-eight structure that is locked on the outer side of the limiting strips 1.1.

[0032] The drive assembly 4 is a hand-cranked drive assembly; the hand-cranked drive assembly includes a drive shaft 4.1, a sprocket 4.2 located at one end of the drive shaft 4.1, and a gearbox 4.3 meshing with the sprocket 4.2. The gearbox 4.3 is equipped with a ratchet 4.31 and a pawl 4.32 structure.

[0033] The frame 1 is divided into upper and lower sections, which are connected by two or more sets of adjustment components 9 that can adjust the distance between the two sections. The adjustment components 9 include connecting blocks 9.1 connected to the upper and lower sections respectively. One connecting block 9.1 is connected to a screw 9.2, and the other connecting block 9.1 is provided with a through hole 9.3 through the screw 9.2. After the screw 9.2 passes through the through hole 9.3, it is limited by a nut 9.4 screwed onto the screw 9.2 and located on one side of the through hole 9.3.

[0034] The target tooth assembly 3 includes a target tooth rod 3.1 and several parallel V-shaped target tooth pieces 3.2 located on the target tooth rod 3.1. When the target tooth assembly 3 rotates to the grid plate 5, the V-shape of the V-shaped target tooth pieces 3.2 faces upward. A reinforcing rib 3.3 is provided between the V-shaped target tooth pieces 3.2 and the V-shaped target tooth pieces 3.2. The reinforcing rib is located at the side plate where the V-shaped target tooth pieces 3.2 are inserted into the grid plate 5, and there is a distance between the reinforcing rib 3.3 and the free end of the side plate of the V-shaped target tooth pieces 3.2.

[0035] During operation, the drive assembly 4 drives the ring chain 2 to rotate, which in turn drives the target tooth assembly 3 to move. As the target tooth rod 3.1 on the target tooth assembly 3 moves upward, it inserts between the grid bars 6 of the grid plate 5, thus removing the debris stuck in the grid plate 5. When the frame 1 needs maintenance, it can be lifted out directly, leaving the grid plate 5 underwater. After maintenance, the rotating rod 8 on the frame 1 is inserted into the screw-fit notch 7.1, and while rotating, the two limiting strips 1.1 are inserted between the two locking strips 5.1, ensuring that the frame 1 and the grid plate 5 are perfectly aligned. This ensures that the target tooth rod 3.1 can accurately move upward between the grid bars 6 of the grid plate 5, preventing the target tooth rod 3.1 from hitting the grid bars 6 if the frame 1 and the grid plate 5 are not perfectly aligned.

[0036] The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
