Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a trolley for fixing an impregnation water gun head. Background Technology

[0002] The pulping center uses secondary sedimentation tank water to spray wood chip stacks, ensuring the wood chips are fully pre-impregnated and reducing the amount of chemicals used. However, spraying the wood chip stacks with secondary sedimentation tank water requires workers to hold the spray nozzle and maintain a stable angle. The problems are: 1. High labor intensity; 2. Prolonged contact with the secondary sedimentation tank water can cause skin corrosion and harm to workers' health due to the chemicals in the water.

[0003] Existing technology, such as the patent document with publication number CN213529878U, discloses a novel high-pressure washer with a traveling trolley. The traveling trolley has a support platform, and the top of the support platform has, from left to right, a water tank, a filter device, and a cleaning device, all connected by water pipes. The top of the water tank has a water inlet. However, this method requires manual operation of the water gun, making it inconvenient to use.

[0004] Patent document CN206150053U discloses a garden irrigation device, including casters, a trolley base, a water tank, a motor housing, and stirring shafts. Casters are installed below the trolley base, and a water tank is located above it. Three stirring shafts are installed inside the water tank. The bottom end of each stirring shaft penetrates the trolley base and is connected to the output end of the stirring motor housing at the bottom of the trolley base via a pulley structure. A stirring rod is fixed to each stirring shaft. A water pump is installed at one end inside the water tank, and the output end of the water pump is connected to an internal connection. The device includes an inner water pipe connected to the lower end of an outer water pipe via a rotating bearing. A motor housing is located on one side of the outer water pipe, housing an electric motor connected to the rotating bearing via a belt. An electric telescopic rod mounted on the outer wall of the outer water pipe connects to a water gun at its output end, and the upper end of the outer water pipe connects to the water gun via a hinged structure. A water inlet is located above the water tank, with a pressure reducing valve on one side. A seat is mounted on the floor of a small cart on one side of the water tank, with a battery installed underneath. A control panel is located in front of the seat. The water gun, connected to the water pipe, sprays water omnidirectionally via the telescopic rod and rotating shaft. The device transports water from the tank to the spraying position and then sprays the water. This device has a complex structure, high initial investment costs, and limited water storage capacity. Utility Model Content

[0005] The main purpose of this utility model is to provide a water gun head fixing trolley with low equipment investment cost, which can continuously spray water from the secondary sedimentation tank onto wood chips.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A water gun head fixing trolley includes a base plate with two universal wheels installed at the front end and two directional wheels installed at the rear end. An adjusting bolt is threadedly connected to the rear end of the base plate in the vertical direction, passing through the base plate. A top plate is rotatably connected to the lower end of the adjusting bolt. A vertical flower rod is fixed to the front end of the base plate, and a sliding sleeve is slidably fitted on the flower rod. A first locking handle is threadedly connected to the sliding sleeve. A rotating sleeve is concentrically rotatably connected to the upper end of the sliding sleeve, and a handle is elastically rotatably connected to the rotating sleeve. An outer sleeve is fixed to the handle, and a spray pipe is inserted into the outer sleeve. The spray pipe is connected to a water pipe, which is connected to the outlet of a water pump. The inlet of the water pump is connected to a secondary sedimentation tank.

[0008] Specifically, a diagonal rod is rotatably connected to one side of the sliding sleeve. The end of the diagonal rod away from the sliding sleeve is inclined downward. A long groove is opened at the lower part of the diagonal rod. The length direction of the long groove is parallel to the length direction of the diagonal rod. An ear plate is fixed on the bottom plate. A pin is fixed on the ear plate. The pin passes through the long groove. Part of the water pipe behind the nozzle is supported by the diagonal rod.

[0009] Specifically, the rotating sleeve is threaded with a second locking handle.

[0010] Specifically, the outer sleeve is threaded with a locking screw, which is tightly pressed against the nozzle.

[0011] Specifically, the handle and the rotating sleeve are connected by a torsion spring.

[0012] Specifically, a positioning bolt is threaded onto the diagonal bar on the front side of the handlebar. The positioning bolt passes through the diagonal bar, and the upper end of the positioning bolt abuts against the lower end of the outer sleeve on the rear side of the handlebar.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device uses a diagonal brace to support the water pipe section behind the nozzle, which prevents a large bending angle at the connection between the water pipe and the nozzle from affecting the entry of water from the secondary sedimentation tank into the nozzle.

[0015] 2. By rotating the adjusting bolt, the top plate is brought into contact with the ground and the directional wheel is separated from the ground. Then, the front end of the fixed trolley can rotate around the axis of the top plate, which facilitates a wide range of adjustment of the spray angle of the nozzle.

[0016] 3. The angle of the nozzle and its circumferential angle on the sliding sleeve can be adjusted within a small range by using the lever, which makes it convenient to adjust the direction of the nozzle spraying water into the secondary settling tank onto the wood chips, and can evenly spray water into the secondary settling tank onto the wood chips.

[0017] 4. By setting a positioning bolt, the tilt angle of the nozzle can be limited. Since the handle and the rotating sleeve are connected by a torsion spring, the nozzle tip tends to swing upward under the elastic force of the torsion spring. The positioning bolt can block the nozzle part behind the handle. Therefore, adjusting the positioning bolt can change the tilt angle of the nozzle. After adjusting the tilt angle of the nozzle by the positioning bolt, the nozzle can continuously spray secondary sedimentation tank water to the designated position of the wood chips.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-4 As shown, a water gun head fixing trolley includes a base plate 1. A vertical slatted rod 9 is fixed to the front end of the base plate 1. A sliding sleeve 10 is slidably fitted on the slatted rod 9. A first locking handle 12 is threadedly connected to the sliding sleeve 10. A rotating sleeve 11 is concentrically rotatably connected to the upper end of the sliding sleeve 10. A second locking handle 13 is threadedly connected to the rotating sleeve 11. A handle 16 is elastically rotatably connected to the rotating sleeve 11. Specifically, the handle 16 and the rotating sleeve 11 are connected by a torsion spring. An outer sleeve 15 is fixed to the handle 16. A spray pipe 17 is inserted into the outer sleeve 15. A locking screw is threadedly connected to the outer sleeve 15, and the locking screw abuts against the spray pipe 17. The spray pipe 17 is connected to a water pipe 18, which is connected to the outlet of a water pump. The inlet of the water pump is connected to a secondary sedimentation tank.

[0025] When spraying water from the secondary sedimentation tank onto the wood chips, the nozzle 17 connected to the water pipe 18 is passed through the outer sleeve 15, and then the locking screw is turned to fix the nozzle 17 inside the outer sleeve 15.

[0026] Loosening the first locking handle 12 allows the sliding sleeve 10 to move up and down on the flower rod 9, thereby adjusting the height of the spray nozzle 17 and the handle 16, making it easier for employees of different heights to operate the handle 16. Simultaneously, it adjusts the water outlet height of the spray nozzle 17, suitable for spraying secondary sedimentation tank water onto wood chips of different heights. After adjusting the height of the spray nozzle 17 and the handle 16, turning the first locking handle 12 positions the sliding sleeve 10.

[0027] The operator can adjust the tilt angle of the spray nozzle 17 by rotating the lever 16, making it convenient to spray water from the secondary settling tank at different heights of the wood chips. The lever 16 causes the outer sleeve 15, the spray nozzle 17, and the rotating sleeve 11 to rotate around the axis of the flower rod 9. The spray nozzle 17 can be adjusted within a small range of angles in the circumferential direction of the rotating sleeve 11, thereby increasing the spraying area from the spray nozzle 17.

[0028] Example 2: Based on Example 1, referring to... Figures 1-4 As shown, a positioning bolt 14 is threaded onto the diagonal bar 8 on the front side of the handlebar 16. The positioning bolt 14 passes through the diagonal bar 8, and the upper end of the positioning bolt 14 is tightly abutted against the lower end of the outer sleeve 15 on the rear side of the handlebar 16.

[0029] By setting the positioning bolt 14, the tilt angle of the nozzle 17 can be limited. Since the handle 16 and the rotating sleeve 11 are connected by a torsion spring, the front end of the nozzle 17 tends to swing upward under the elastic force of the torsion spring. The positioning bolt 14 can block the nozzle 17 part behind the handle 16. Therefore, adjusting the positioning bolt 14 can change the tilt angle of the nozzle 17. After adjusting the tilt angle of the nozzle 17 by the positioning bolt 14, the nozzle 17 can continuously spray secondary sedimentation tank water to the designated position of the wood chips.

[0030] Example 3: Based on Example 1, referring to... Figures 1-4 As shown, two universal wheels 2 are installed at the front end of the base plate 1, and two directional wheels 3 are installed at the rear end of the base plate 1. An adjusting bolt 19 is threaded in the vertical direction at the rear end of the base plate 1. The adjusting bolt 19 passes through the base plate 1, and a top plate 4 is rotatably connected to the lower end of the adjusting bolt 19.

[0031] By rotating the adjusting bolt 19, the top plate 4 is brought into contact with the ground and the directional wheel 3 is separated from the ground. Then, the front end of the fixed trolley can rotate around the axis of the top plate 4, which facilitates a wide range of adjustment of the spray angle of the nozzle 17.

[0032] Example 4: Based on Example 1, referring to... Figures 1-4As shown, a diagonal rod 8 is rotatably connected to one side of the sliding sleeve 10. The end of the diagonal rod 8 away from the sliding sleeve 10 is inclined downward. A long groove 7 is opened at the lower part of the diagonal rod 8. The length direction of the long groove 7 is parallel to the length direction of the diagonal rod 8. An ear plate 5 is fixed on the bottom plate 1. A pin 6 is fixed on the ear plate 5. The pin 6 passes through the long groove 7. The part of the water pipe 18 behind the spray pipe 17 is supported by the diagonal rod 8.

[0033] This device, by setting up a diagonal rod 8, can support the water pipe 18 section behind the nozzle 17, which can prevent the water pipe 18 from having a large bending angle at the connection between the nozzle 17 and the nozzle 17, thus affecting the entry of the secondary sedimentation tank water into the nozzle 17.

[0034] After the height of the nozzle 17 changes, the tilt angle of the inclined rod 8 also changes accordingly, which can ensure that the inclined rod 8 provides effective and continuous support for the water pipe 18 on the rear side of the nozzle 17.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
