Description

Technical Field

[0001] The utility model belongs to the field of special-purpose vehicles, and in particular relates to a spray bar angle adjustment structure. Background Art

[0002] A washing and sweeping vehicle has the functions of spraying water and cleaning garbage. It can complete road cleaning while moving and has been widely used in urban cleaning. However, current washing and sweeping vehicles generally use fixed nozzles, and the water spraying angle cannot be adjusted, which easily leads to cleaning dead corners. Therefore, the market is in urgent need of a spray bar structure that can automatically adjust the nozzle angle.

[0003] Patent CN109926214A discloses a swinging nozzle, which is mainly used in car washers. Although the structure can realize nozzle swing, it is not compact enough and the moving parts swing greatly, which is not suitable for the actual working conditions of washing and sweeping vehicles. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the spray bar angle of the washing and sweeping vehicle in the prior art is difficult to adjust, and a spray bar angle adjustment structure is provided.

[0005] In order to solve the problems in the prior art, the utility model specifically adopts the following technical solutions: a spray rod angle adjustment structure, including a motor, a T-type right-angle reducer, a spray rod, a nozzle, a rotary joint, and a bearing seat. The output end of the motor is connected to the T-type right-angle reducer, and the two output ends of the T-type right-angle reducer are respectively connected to a spray rod, and the two spray rods are coaxially symmetrically arranged. A plurality of nozzles are installed on the spray rod, and a plug is provided at one end of the spray rod close to the T-type right-angle reducer, and the end away from the T-type right-angle reducer is connected to a water supply equipment through a rotary joint. Each spray rod is provided with one or more bearing seats, and the bearing seat and the T-type right-angle reducer are fixedly mounted on the same bracket. The motor is centrally located, and the T-type right-angle reducer has one input and two outputs, which can drive two spray booms to rotate at the same time. Compared with a single spray boom, the structure used in this case has a shorter length of each spray boom, so the pressure uniformity of each nozzle is more consistent, which can improve the uniformity of water spraying from each nozzle. The spray boom is installed through a bearing seat, which can achieve more flexible rotation. A swivel joint is set at the end of the spray boom, which can effectively achieve uninterrupted water supply during rotation.

[0006] Furthermore, two limit sensors are installed on the bracket, and corresponding induction trigger components are installed on the spray rod. Since the nozzle angle adjustment does not require 360 ​​degrees, the initial and limit positions can be adjusted by the limit sensors on both sides. After the limit sensors detect that they are in place, the motor can be flipped, and the two limit sensors can limit the nozzle to reciprocate at a fixed swing angle. The motor can also be powered off and locked by the internal mechanical structure of the reduction motor to achieve nozzle angle locking.

[0007] Furthermore, the limit sensor adopts a proximity switch, which has high sensitivity and is easy to install.

[0008] Furthermore, the induction trigger component includes a first fixed ring, a second fixed ring, a movable ring, and a spring. The first fixed ring and the second fixed ring are fixedly mounted on the spray rod. The movable ring is located between the first fixed ring and the second fixed ring and can slide along the surface of the spray rod. A spring is installed between the first fixed ring and the movable ring. A matching radial toothed surface is provided between the second fixed ring and the movable ring. A protrusion that can trigger the proximity switch is provided on the movable ring. Under normal conditions, the movable ring is subjected to the thrust of the spring and is locked with the second fixed ring through the toothed surface and cannot rotate. When the angle of the protrusion needs to be adjusted, the movable ring is moved, and after the spring is compressed, the movable ring is rotated to the target angle, and then pushed by the spring to achieve locking. Therefore, the nozzle swing angle can be adjusted very conveniently.

[0009] Furthermore, the limit sensor and the induction trigger component are both located near the two ends of the spray rod. Since they are close to the ends of the spray rod, manual operation is more convenient without drilling under the vehicle for adjustment.

[0010] Furthermore, the output end of the T-type right-angle reducer and the spray rod are connected via an expansion sleeve, which facilitates disassembly and assembly.

[0011] Beneficial effects of the utility model:

[0012] 1. The motor of the utility model is centrally placed, and the T-type right-angle reducer has one input and two outputs, which can drive two spray rods to rotate at the same time. Compared with a single spray rod, the length of each spray rod used in this case is shorter, so the uniformity of the pressure of each nozzle is more consistent, which can improve the uniformity of water spraying from each nozzle.

[0013] 2. The utility model has a rotating joint at the end of the spray rod, which can effectively realize uninterrupted water supply during rotation.

[0014] 3. The induction trigger component of the utility model can adjust the swing angle of the nozzle by simply moving and rotating the movable ring, which is very easy to adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, as Figure 1 A spray bar angle adjustment structure shown in the figure includes a motor 1, a T-type right-angle reducer 2, a spray bar 3, a nozzle 4, a rotary joint 5, and a bearing seat 6. The output end of the motor 1 is connected to the T-type right-angle reducer 2, and the two output ends of the T-type right-angle reducer 2 are respectively connected to a spray bar 3. The two spray bars 3 are coaxially symmetrically arranged. A plurality of nozzles 4 are installed on the spray bar 3. A plug is provided at one end of the spray bar 3 close to the T-type right-angle reducer 2, and the end away from the T-type right-angle reducer 2 is connected to a water supply device through a rotary joint 5. One or more bearing seats 6 are provided on each spray bar 3, and the bearing seat 6 and the T-type right-angle reducer 2 are fixedly installed on the same bracket. In this solution, the motor 1 is centrally placed, and the T-type right-angle reducer 2 has one input and two outputs, which can drive two spray rods 3 to rotate at the same time. Compared with a single spray rod 3, the structure used in this case has a shorter length of each spray rod 3, so the uniformity of the pressure of each nozzle 4 is more consistent, which can improve the uniformity of water spraying from each nozzle 4. The spray rod 3 is installed through a bearing seat 6, which can achieve more flexible rotation. A rotating joint 5 is set at the end of the spray rod 3, which can effectively achieve uninterrupted water supply during rotation.

[0022] In actual application, two limit sensors 7 are installed on the bracket, and corresponding induction trigger components 8 are installed on the spray rod 3. Since the angle adjustment of the nozzle 4 does not need 360 degrees, the initial and limit positions can be adjusted by the limit sensors 7 on both sides. After the limit sensors 7 detect that they are in place, the motor 1 can be turned over, and the two limit sensors 7 can limit the nozzle 4 to reciprocate at a fixed swing angle. The motor 1 can also be powered off and locked by the internal mechanical structure of the reduction motor 1 to achieve the angle locking of the nozzle 4.

[0023] Embodiment 2, as Figure 2-4As shown, the difference from the first embodiment is that the limit sensor 7 adopts a proximity switch, which has high sensitivity and is easy to install. The induction trigger component 8 includes a first fixed ring 801, a second fixed ring 802, a movable ring 803, and a spring 804. The first fixed ring 801 and the second fixed ring 802 are fixedly sleeved on the spray rod 3. The movable ring 803 is located between the first fixed ring 801 and the second fixed ring 802 and can slide along the surface of the spray rod 3. A spring 804 is installed between the first fixed ring 801 and the movable ring 803. A matching radial toothed surface is provided between the second fixed ring 802 and the movable ring 803. A protrusion 805 capable of triggering the proximity switch is provided on the movable ring 803. Under normal conditions, the movable ring 803 is pushed by the spring 804 and locked with the second fixed ring 802 through the toothed surface, and cannot rotate. When the angle of the protrusion 805 needs to be adjusted, the movable ring 803 is moved, and after the spring 804 is compressed, the movable ring 803 is rotated to the target angle, and then pushed by the spring 804 to achieve locking. Therefore, the swing angle of the nozzle 4 can be adjusted very conveniently. The limit sensor 7 and the induction trigger component 8 are both located near the two ends of the spray rod 3. Because it is close to the end of the spray rod 3, manual operation is relatively convenient, and there is no need to drill under the vehicle for adjustment. The output end of the T-type right-angle reducer 2 and the spray rod 3 are connected by a tightening sleeve 9, which is convenient for disassembly and assembly.

[0024] In summary, the spray boom angle adjustment structure of the utility model can realize the free rotation and control of the angle of the long spray boom nozzle, thereby improving the working quality of the washing and sweeping vehicle.

[0025] The above shows and describes the basic principles, main features and advantages of the utility model.
