Description

TECHNICAL FIELD

[0001] The utility model relates to a spraying vehicle technical field, especially a kind of automatic retractable conduit device. BACKGROUND

[0002] Spraying vehicle needs to be conveyed to the spraying head by water pipe when spraying along seedbed, so longer water pipe is needed to achieve the above purpose;Since the main line reel water pipe is stacked by layer, so in the different diameter of retraction, in the case of angular velocity, its linear velocity is inconsistent, at the same time, vehicle speed is uniform, so it will cause the distance of vehicle travel and the length of water pipe retraction inconsistent, for example, in the pipeline output process, when the speed of pipeline output is greater than vehicle speed, it will not be able to effectively spit all pipeline outside the vehicle, but loose and messy winding on the wire roller, even fill the vehicle cavity, resulting in jam. Therefore, a set of device capable of automatically retracting or releasing water pipe is needed to meet the above needs. SUMMARY

[0003] The utility model solves the technical problems: in order to solve the problem that the water pipe of the existing spraying device is easy to loose and messy, the utility model provides an automatic retractable conduit device.

[0004] The technical scheme adopted by the utility model to solve its technical problems is: an automatic retractable conduit device, including main line reel, pre-tightening spring, pipe pressing and winding mechanism and pre-tightening spring, the main line reel is arranged in the middle of spraying vehicle frame, the pre-tightening spring is connected with the pre-tightening spring, and the pipe pressing and winding mechanism is arranged on the upper side of the main line reel.

[0005] Further, one side of the pre-tightening spring is connected with the pre-tightening spring, and the other side is connected with the pre-tightening spring; the side surface of the main line reel is connected with the rotating water pipe joint, and the other side of the main line reel is connected with the moving motor of the spraying device through the chain, in the output pipeline stroke, the motor rotation linear speed is greater than the main pipe line speed, drives the driving wheel to rotate, that is, the pipe line can be pulled out from the vehicle body under the friction force between the pipe line and the friction wheel.

[0006] Further, the pre-tightening spring includes pressing wheel and driving wheel, the pressing wheel is arranged above the water pipe, and the driving wheel is arranged below the water pipe, and the driving wheel and the pressing wheel cooperate to realize the retraction of the water pipe.

[0007] Further, one end of the pre-tightening spring is connected with the pressing wheel, and the other end is connected with the winding frame.

[0008] Furthermore, the tube pressing and cable laying mechanism includes a tube pressing rod, a first connecting rod, a second connecting rod, a fixing rod, and a tension spring; the tube pressing rod is disposed on the upper part of the main cable reel, and the two ends of the tube pressing rod are respectively connected to the first connecting rod and the second connecting rod, and the other ends of the first connecting rod and the second connecting rod are respectively connected to the two ends of the fixing rod.

[0009] Furthermore, one end of the tension spring is connected to the pressure pipe rod, and the other end is connected to the spray truck frame.

[0010] The beneficial effects of this utility model are:

[0011] The automatic cable retraction device of this utility model has a drive wheel that rotates under the drive of a motor, and a clamping wheel that presses the cable tightly between the two friction wheels under the tension of a spring. During the cable output stroke, the linear speed of the motor rotation is greater than the speed of the main cable output, driving the drive wheel to rotate. This allows the cable to be pulled out of the vehicle body under the friction between the cable and the friction wheels, thus ensuring that the cable between the main cable reel and the two friction wheels maintains tension. This avoids the problem of jamming due to excessive length in the vehicle body cavity, which would prevent the water pipe from being output. During the cable retraction stroke, the motor stops rotating, and the cable is pulled back under the rotation of the main cable reel. At this time, the two friction wheels still clamp the cable under the action of the spring, keeping the cable between the main cable reel and the friction wheels under a certain tension, so as to better arrange it on the circumference of the main cable reel.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "horizontal", "top", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figs. 1-3 As shown, an automatic cable reel device includes a main cable reel 1, a pre-tensioning and reeling wheel assembly 2, a pre-tensioning spring 3, a cable pressing and routing mechanism 4, and a pre-tensioning and reeling drive motor 5. The main cable reel 1 is located in the middle of the spray vehicle frame, the pre-tensioning and reeling wheel assembly 2 is connected to the pre-tensioning spring 3, and the cable pressing and routing mechanism 4 is located on the upper side of the main cable reel 1.

[0021] The pre-tensioning and retracting pipe wheel assembly 2 is connected to a pre-tensioning spring 3 on one side and a pre-tensioning and retracting pipe drive motor 5 on the other side. The main cable reel 1 is connected to a rotating water pipe connector 6 on one side, and to a moving motor of the spraying device via a chain 7 on the other side. During the output pipe stroke, the motor's rotational linear speed is greater than the main pipe speed, driving the drive wheel 22 to rotate. This allows the pipe to be pulled out of the vehicle body by the friction between the pipe and the friction wheel. The pre-tensioning and retracting pipe wheel assembly 2 includes a pressure wheel 21 and a drive wheel 22. The pressure wheel 21 is positioned above the water pipe, and the drive wheel 22 is positioned below the water pipe. The drive wheel 22 and the pressure wheel 21 cooperate to retract and extend the water pipe. One end of the pre-tensioning spring 3 is connected to the pressure wheel 21, and the other end is connected to the cable tray.

[0022] The pipe pressing and cable laying mechanism 4 includes a pipe pressing rod 41, a first connecting rod 42, a second connecting rod 43, a fixing rod 44, and a tension spring 45. The pipe pressing rod 41 is located on the upper part of the main cable reel 1. Both ends of the pipe pressing rod 41 are connected to the first connecting rod 42 and the second connecting rod 43, respectively. The other ends of the first connecting rod 42 and the second connecting rod 43 are connected to both ends of the fixing rod 44, respectively. One end of the tension spring 45 is connected to the pipe pressing rod 41, and the other end is connected to the spray truck frame.

[0023] When in use, as the spraying device moves forward, the pre-tensioning and retracting pipe drive motor 5 starts simultaneously, and the drive wheel 22 rotates to release the water pipe. Under the tension of the spring, the clamping wheel 21 can tightly clamp the water pipe between the two wheels, so that the water pipe is always kept taut, avoiding the problem of jamming due to the excessive length in the vehicle body cavity, which would prevent the water pipe from being output. When the spraying vehicle returns, the pre-tensioning and retracting pipe drive motor 5 stops rotating, and the pipeline is pulled back under the action of the rotation of the main line reel 1. At this time, the two friction wheels are still clamping the water pipe under the action of the spring, so that the water pipe between the main line reel 1 and the friction wheels is kept in a certain tension state, so as to better wind around the circumference of the main line reel 1.

[0024] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.
