[0032] The utility model will be further described below in combination with the embodiments shown in the drawings.

[0033] As Figure 1 shown, it is the structure schematic view of the utility model's rotary water spray structure for cleaning mesh belt, and the structure is used for automatically cleaning mesh belt, including rotary joint 1, rotary support 2 and water spray frame 3.

[0034] As Figure 2 shown, it is the structure schematic view of rotary joint 1, and rotary joint 1 includes joint body 101, upper spring retainer groove 102, upper spring retainer 103, first bearing 104, second bearing 105, first pressure ring 106, first cover plate 107, positioning sleeve 108, first water inlet pipe 109, clamping part 110 and bushing 111.Joint body 101 is fixed at the top of the cleaning frame, and a through groove is vertically formed in joint body 101, and first bearing 104 and second bearing 105 are installed in the through groove and abut against each other.

[0035] After rotary joint 1 is subjected to water spray reverse thrust, the axial force acting on the bearing will be very large, so two first bearings 104 and second bearings 105 abutting against each other are installed to improve stability and avoid damage of a single bearing due to a large overturning moment.

[0036] Upper spring retainer groove 102 is formed at the bottom of joint body 101, upper spring retainer 103 is clamped in upper spring retainer groove 102, and upper spring retainer 103 abuts against the bottom of first bearing 104 to prevent axial movement of first bearing 104 downward. First pressure ring 106 is arranged in the through groove of joint body 101 and abuts against the top of second bearing 105 to prevent axial movement of second bearing 105 upward.

[0037] First cover plate 107 is fixed at the top of joint body 101 by screw fastening and abuts against the top of first pressure ring 106. When first cover plate 107 is fixed, first cover plate 107 is pressed against the top of first pressure ring 106, and then first pressure ring 106 is pressed against the top of second bearing 105. First bearing 104 is axially limited by upper spring retainer 103, and second bearing 105 is axially limited by first pressure ring 106.

[0038] The positioning sleeve 108 is embedded in the first pressure ring 106 and the first cover plate 107. The first water inlet pipe 109 vertically penetrates the joint body 101 and is inserted into the positioning sleeve 108, the first bearing 104, and the second bearing 105. The positioning sleeve 108 radially limits the rotation of the first water inlet pipe 109, preventing radial deviation of the first water inlet pipe 109.

[0039] The bushing 111 is sleeved on the first water inlet pipe 109 and inserted into the inner rings of the first bearing 104 and the second bearing 105. When the first water inlet pipe 109 is installed, the bushing 111 can reduce friction and wear between the first water inlet pipe 109 and the first bearing 104 and the second bearing 105, thereby improving rotation accuracy.

[0040] The clamping portion 110 is integrally connected to the bottom of the first water inlet pipe 109, and the first water inlet pipe 109 and the second water inlet pipe 211 are plugged together through the clamping portion 110. A vertical water inlet channel is provided in the first water inlet pipe 109, through which external cleaning water flows into the first water inlet pipe 109 and then flows through the second water inlet pipe 211 to the water spray head 305, thereby completing the cleaning of the mesh belt.

[0041] like Figures 3-5 Figure 2 shows the structure of the rotating support 2, which is fixed to the cleaning rack and located below the rotary joint 1. The rotating support 2 includes a support body 201, an upper support groove 202, a lower support groove 203, an upper bearing 204, a lower bearing 205, a lower spring retaining ring groove 206, a lower spring retaining ring 207, a second cover plate 208, a second pressure ring 209, a spacer 210, a second water inlet pipe 211, a compression nut 212, and a retaining groove 213. The support body 201 also has a vertical through-slot for mounting the second water inlet pipe 211.

[0042] An upper support groove 202 is formed at the top of the support body 201, and an upper bearing 204 is clamped in the upper support groove 202. A lower support groove 203 is formed at the bottom of the support body 201, and a lower bearing 205 is clamped in the lower support groove 203. The upper bearing 204 and the lower bearing 205 are located at the top and bottom of the support body 201, respectively.

[0043] The rotary joint 1 utilizes abutting first and second bearings 104 and 105 to enhance stability and prevent damage to a single bearing due to large overturning moments. However, when subjected to large torques, the force points on the two bearings are too close together, and bearing damage can still occur after a period of use, increasing operating costs. Therefore, a rotary support 2 is added to the bottom of the rotary joint 1. The overturning moment generated by the water jet's reverse thrust is fully applied to the upper and lower bearings 204 and 205 of the rotary support 2.

[0044] Since the upper bearing 204 and the lower bearing 205 in the rotating support 2 are not in contact with each other, the upper bearing 204 is located at the top of the support body 201 and the lower bearing 205 is located at the bottom of the support body 201. The distance between the two is increased, which reduces the chance of damage to the rotating support 2, reduces maintenance costs, and makes it easier to replace bearings, allowing for quick repair and replacement.

[0045] A lower spring retaining ring groove 206 is provided at the bottom of the support body 201. A lower spring retaining ring 207 is retained within the groove 206. The lower spring retaining ring 207 abuts against the bottom of the lower bearing 205, preventing the lower bearing 205 from moving axially downward. A second pressure ring 209 is embedded within the through-slot of the support body 201 and abuts against the top of the upper bearing 204. The second pressure ring 209 is shaped like a "[" and has its opening facing downward. Therefore, the second pressure ring 209 abuts only against the outer ring of the upper bearing 204, avoiding the inner ring of the upper bearing 204. This prevents friction between the second pressure ring 209 and the inner and outer rings of the upper bearing 204 from rotating relative to each other.

[0046] The second cover plate 208 is fixed to the top of the support body 201 by screw fastening, and is against the top of the second pressure ring 209. When the second cover plate 208 is fixed, the second cover plate 208 is pressed on the top of the second pressure ring 209, and then the second pressure ring 209 is pressed on the top of the upper bearing 204, completing the axial limitation of the upper bearing 204 and preventing the upper bearing 204 from axially moving upward.

[0047] The second water inlet pipe 211 is vertically inserted into the support body 201 and inserted between the upper bearing 204 and the lower bearing 205. When the second water inlet pipe 211 rotates, the upper bearing 204 and the lower bearing 205 improve the rotational stability of the second water inlet pipe 211. A clamping groove 213 is provided at the top of the second water inlet pipe 211. When the first water inlet pipe 109 and the second water inlet pipe 211 are connected, the clamping portion 110 at the bottom of the first water inlet pipe 109 is inserted into the clamping groove 213 of the second water inlet pipe 211 with an interference fit, completing the fixed connection between the first water inlet pipe 109 and the second water inlet pipe 211.

[0048] The spacer 210 is mounted on the top of the second water inlet pipe 211 and abuts the inner ring of the upper bearing 204. The second water inlet pipe 211 is provided with an external thread at one end near the first water inlet pipe 109. The compression nut 212 is screwed onto the top of the second water inlet pipe 211 and abuts the top of the spacer 210. As the compression nut 212 is screwed, the spacer 210 is gradually pushed downward, and the spacer 210 then abuts against the inner ring of the upper bearing 204, compressing the inner ring of the upper bearing 204 and improving the rotational stability of the upper bearing 204.

[0049] A water inlet channel is provided in the second water inlet pipe 211 , and external cleaning water flows into the first water inlet pipe 109 , and then flows to the water spray head 305 through the second water inlet pipe 211 to complete the cleaning of the mesh belt.

[0050] like Figure 6 、 7 Figure 2 shows the structure of the water spray frame 3, which includes a main water spray frame 301, a sub-water spray frame 302, an adapter 303, a fixing groove 304, a water spray head 305, a main water spray channel 306, a transition channel 307, and a sub-water spray channel 308. The main water spray frame 301 is fixed to the bottom of the second water inlet pipe 211, and the sub-water spray frame 302 is integrally connected to both sides of the main water spray frame 301. Both the main water spray frame 301 and the sub-water spray frame 302 are provided with water inlet channels that communicate with the second water inlet pipe 211.

[0051] The adapter 303 is fixed to the outside of the water spray sub-frame 302 by means of a threaded connection. The fixing groove 304 is obliquely opened at the bottom of the adapter 303. An internal thread is opened in the fixing groove 304. An external thread is opened on the outside of the water spray head 305. The water spray head 305 is fixed to the bottom of the adapter 303 by means of threaded fitting.

[0052] The main water spray channel 306, the transition channel 307 and the auxiliary water spray channel 308 are opened in the water spray head 305 from the inside to the outside in sequence. The external cleaning water passes through the first water inlet pipe 109 and the second water inlet pipe 211, and then flows to the water spray head 305, and completes the cleaning work of the mesh belt through the main water spray channel 306, the transition channel 307 and the auxiliary water spray channel 308.

[0053] The transition channel 307 tapers in diameter from inside to outside, thereby increasing the pressure in the auxiliary water spray channel 308 to improve the cleaning effect of the mesh belt. When cleaning the mesh belt, the first water inlet pipe 109 and the second water inlet pipe 211 rotate, thereby driving the water spray head 305 to rotate synchronously, improving the cleaning efficiency of the mesh belt and avoiding blind spots in the cleaning process.

[0054] To facilitate the installation of the driving mechanism, a first gear can be installed at the bottom of the second water inlet pipe 211, and a second gear meshing with the first gear can be installed on the cleaning rack. The second gear is driven to rotate by the motor on the cleaning rack, thereby driving the second water inlet pipe 211 and the first water inlet pipe 109 to rotate.

[0055] The cleaning principle of the rotary water spray structure for cleaning the mesh belt of the utility model is as follows:

[0056] Firstly, the cleaning water is introduced into the first water inlet pipe 109, and the cleaning water passes through the first water inlet pipe 109 and the second water inlet pipe 211, and finally sprays the net belt downwards through the main water spraying flow channel 306, the transition flow channel 307 and the auxiliary water spraying flow channel 308, so that the cleaning work of the net belt is completed, which can improve the cleaning coverage, avoid the occurrence of cleaning blind area, improve the cleaning efficiency, reduce the damage probability of the rotating support, reduce the maintenance cost, and more easily replace the bearing, and fast repair and fast replacement can be realized.

[0057] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
