Description

Hose Reel for Agriculture {FARMING HOSEREEL}

The present invention relates to an agricultural hose reel, and more particularly, to provide a power transmission device that facilitates the unwinding and winding of a hose for supplying a liquid to be sprayed in conjunction with an atomizer for controlling or watering in a farm. It is about.

It is a hose that delivers the liquid supplied from the sprayer to the crop in connection with the sprayer used for spraying pesticides or supplying water or nutrients or liquid fertilizers to the crop for pest control of crops.

Agricultural hose reels are developed and used to help the farmers' lack of work by mechanically performing the winding and unwinding of the hoses more easily, and various types of these hose reels have been developed, among which the representative conventional technologies Looking through 4 as follows.

The hose reel (1) to which the prior art is applied is provided with a bobbin (3) so that the hose can be wound and released on the frame (2), and the bobbin (3) is driven by the driving means (4) installed on the frame (2). Receive and rotate.

The bobbin 3 is naturally rotated when the hose is released, and the driving means 4 is operated only when the hose is to be wound, so that the bobbin 3 can be wound by rotating the bobbin 3, and the upper part of the bobbin 3 An ordinary traverse is installed in the hose which moves the hose to the left and right directions of the bobbin so that the hose can be wound up neatly.

A portion of the power transmission to the bobbin is provided with a clutch to select the power transmission, the clutch is configured in various forms, such as the type of adjusting the tension of the belt for transmitting power, the dog clutch type installed on the bobbin shaft. Doing.

In the prior art as described above, in order to wind the hose by driving the bobbin constituting the hose reel, the power of the driving means must be transmitted to the hose reel. In this process, the clutch must be operated in this process.

That is, when the relaxed part of the belt which transmits the power of the driving means to the bobbin so as not to slip occurs, the power can be switched only through connection or detachment such as engaging the dog clutches installed on the bobbin shaft with each other. It is.

In the related art, since the clutch is mechanically operated and not operated, the operator who is performing the spraying operation has to move to the hose reel and operate the clutch or operate the clutch while the assistant is standing by. will be.

In this prior art, it is not suitable for a rural situation where one hand is insufficient because it requires an additional hand, and thus it is not convenient to use the clutch every time the hose is wound and released.

In addition, since a pulley and a belt combination are used as means for transmitting the power of the motor to the bobbin and the traverse, a considerable weight is generated when the length of the hose wound on the bobbin is long, and this weight causes the motor to wind the bobbin. In the process of transmitting the necessary power, slip occurs between the pulley and the belt, and smooth operation cannot be expected.

In particular, agricultural hose reels are used to spray pesticides for control, water for hydration, nutrients or liquid fertilizers for nutrients to crops, so they are always exposed to moisture. If water is introduced into the slip phenomenon is further intensified, such as the situation that there is a number of problems such as impossible to wound the hose.

The present invention as described above has been devised to solve the above problems, the drive means to be installed on the lower side of the frame, the bobbin installed in the middle of the frame is held on the bobbin shaft to wind and unwind the hose, and the In the agricultural hose reel consisting of a traverse installed on the top to be wound on the bobbin in a neat state;

The power transmission means for transmitting the power of the driving means to the bobbin shaft and the traverse shaft is improved by a chain gear and a chain combination so that there is no slip phenomenon, and the power transmission means stops the rotation of the bobbin when the worker stops drawing the hose. By further installing a brake to prevent the backlash of the hose, it has a feature that can ensure a smooth operability while increasing the quality and durability of the hose reel.

The present invention not only can smoothly transmit the hose reel by accurately transmitting power, but also stops the bobbin through the magnet brake to prevent the entanglement of the hose, thereby improving the workability while improving the quality of the hose reel. It is devised to have various effects.

The perspective of the power transmission part of the thrill is described together.

Conventional agricultural hose reel 100 is provided with a drive means 102 in the lower side of the frame 101, the intermediate position of the frame 101 is held on the bobbin shaft 103 to wind and release the hose 104 The bobbin 105 is installed.

The upper part of the bobbin 105 is configured by installing a conventional traverse 106 so that the hose 104 wound on the bobbin 105 can be evenly wound on the entire bobbin 105 in a neat state.

In the present invention, the power transmission means 110 for transmitting the power of the driving means 102 to the bobbin shaft 103 and the traverse shaft 107 is improved, and the worker has a hose 104 in the power transmission means 110. When stopping the withdrawal of the bobbin 105 by stopping the rotation of the hose 104 to prevent backlash is characterized in that the installation further.

The power transmission means 110, the drive chain gear 113 is fixed to the drive shaft 112 of the drive means 102, the transmission shaft 114 is installed below the bobbin 105 spaced apart from the drive shaft 112. ) Is connected to the chain 116 by fixing the one transfer chain gear (115).

The drive means 102 by connecting the reduction chain gear 117 fixed to the outer side of the first transmission chain gear 115 and the bobbin drive chain gear 118 fixed to the outside of the bobbin shaft 103 with a chain 119. The power of the deceleration is to be transmitted to the bobbin 105.

The two transmission chain gears 120 are fixed to the inside of the bobbin shaft 103 and connected to the traverse chain gear 121 and the chain 122 fixed to the traverse shaft 107 so that the power of the driving means 102 is increased. Regardless of the load of the hose 104 wound around the bobbin 105 or the inflow of water generated in the working process, the power can be transmitted in a stable state.

The brake 111 is mounted by a conventional magnet brake that operates by receiving an electric signal inside the transmission shaft 114, and is controlled by the controller 125 receiving the movement of the traverse 106 to perform braking. To help.

Although the brake 111 is illustrated as being mounted on the transmission shaft 114 in the present invention, the transmission shaft 114 and the bobbin shaft 103 may be mounted on any one of the driving shaft 112 as well.

In addition, the brake 111 can be switched back to the released state after the braking operation by the controller 125 so that the pull-out of the hose 104 is prevented, and the electrical control of the brake 111 is such that Since the technical matters generally known in the art, detailed description thereof will be omitted.

Referring to the state of use of the agricultural hose reel 100 to which the technology of the present invention is applied as follows.

When the hose 104 is wound around the bobbin 105 constituting the hose reel 100 and the end thereof is positioned on the traverse 106, the hose 104 is sprayed when the hose 104 is to be used. Used in conjunction with the pole.

When the operator wants to perform the spraying operation, the bobbin 105 is naturally idled by the pulling force of the hose 104 when the worker pulls the spray pole, and is released, and the driving means (when the winding of the released hose 104 is to be wound) By operating the 102 using a remote control or a switch provided in the hose reel 100, etc. that the operator is carrying the bobbin 105 is rotated in the reverse direction of the released direction it is possible to wind the hose 104 released .

Thus, even if the weight of the bobbin 105 on which the hose 104 is wound is heavy or water is introduced into the power transmission unit 110 in the process of performing the operation of unwinding and winding the hose 104, the chain gear and the chain Because of the connection, power can be accurately transmitted without slipping, thereby ensuring smooth operation.

Then, when the worker pulls the hose 104, the traverse 106 detects the movement (generally leaned in the pulling direction) and applies it to the controller 125 to switch the brake 111 to the released state, and the hose ( Even when the pulling of 104 is stopped, the traverse 106 detects the return to its original position and the controller 125 activates the brake 111 to stop the bobbin 105 from continuing to rotate by inertia. do.

Of course, it will be obvious that the brake 111 does not interfere with the next pulling operation by stopping the rotation of the bobbin 105 and immediately switching to the released state by the controller 125.

The present invention can not only smooth the operation of the hose reel by power transmission accurately, but also stop the bobbin through the magnet brake to prevent the entanglement of the hose to improve the workability while improving the quality of the hose reel. Has the advantage.
