It connects the front and rear connection pipe which can rotate the pulley and driving pulley with little force. The rear connection pipe is folded by the coupling means of the rear connection pipe so that it can be easily stored. It is supported by the front and rear wheels and proceeds in a balanced state, so it is possible to carry the crop in a very stable state without fear of overturning, and when the stand is stopped to load the crop, the pedestal supports both sides of the loading box. The crops can be loaded in a stable state without falling to the right side, and the front wheel is steered by the rotation of the rear connection tube to guide the rear wheels. It is possible to fold back connection pipe which is combined with rear connection pipe. It can be prevented and can be stored in a small volume during storage, and the front connecting pipe combined with the front connecting pipe can be easily used when reversing because it can be separated and combined. It is related to the steering device of the crop transport cart which can load and transport large weight crops easily with low power due to the low center of gravity which is lower than the center line.

Conventionally, when the crops produced in fields with melon, cucumber, tobacco, etc. are loaded and transported to a warehouse, a unicycle was used.

The configuration of the wheelbarrow includes a loading box capable of loading crops, one wheel coupled to rotate forward of the bottom of the loading box, a support protrudingly coupled to both sides of the bottom of the loading box, and an upper rear of the loading box. It is configured with a handle that is connected.

In the conventional unicycle with the above configuration, when the crop is loaded, the wheels and the support stand maintain the support state while touching the ground.

Then, after loading the crop in the stacker, the worker proceeds after lifting the handle slightly.

In other words, when the worker lifts the handle, only the wheel of the worker's foot and the trolley is in contact with the ground.

Therefore, the worker has to carry the load acting as a load while carrying out the weight, it was a very strong conveyance work.

In addition, the unicycle is very difficult to balance the front, rear, left and right, so even when loading crops in the loading cart had to be loaded so that the even load distribution is applied to the loading box and only the skilled man driving the wheelbarrow It was inconvenient and cumbersome because I could do this trick.

And, even when the direction of the crop loaded in the cart, it was necessary to change the direction by the force of the person, so that the load to fall to the left and right to fall over the load, and many of the crops of the loading box, etc. Had a problem.

The purpose of the present invention for solving and solving these conventional problems,

The front and rear loads of the loading box are supported by the front and rear wheels to proceed in a balanced state, so it is possible to carry crops in a very stable state without fear of overturning. Can support the both sides of the loading box so that the crops can be loaded in a stable state without falling to the left and right sides, and the front wheel is steered by the rotation of the rear connection tube to guide the rear wheels. It is possible to change the direction with little force in one state and to fold the rear connection pipe which is combined with the rear connection pipe to prevent the jam when loading crops, and to keep it in small volume when storing. The front connecting pipe coupled with the pipe can be easily used when reversing because it can be separated and combined. The purpose was to provide help to the bottom of the charger before, can let a small force by the low center of gravity, which came down to the lower side than the center line of the rear wheels for easy loading and carrying the weight of a large crop.

In order to achieve the above object, the present invention,

A plurality of auxiliary pulleys 108 which are installed on the outer periphery of the loading box 107 for smooth driving of the transmission member 104 to support the transmission member 104;

The front and rear connecting pipes 112 and 102 are coupled to the upper side of the front and rear connecting pipes 112 and 102 and driven pulleys 113 and the front pulleys 104 to rotate with a small force, Rear connecting pipes 115 and 103,

The rear connection pipe 103 is configured to be provided with a coupling means of the rear connection pipe for easy storage by folding.

And, the coupling means of the rear connecting pipe is a central shaft 122 for coupling the fixing bracket 127 of the rear connecting pipe 102 and the connecting piece 121 of the rear connecting pipe 103 so as to rotate,

Rotating to the coupling piece 123 of the rear connection tube 103 to be inserted and separated by the locking hole 126 formed in the support piece 125 of the rear connection pipe 102 while rotating by the central axis (122). It was equipped with a locking shaft 124 coupled so.

In addition, the pedestal 137 is coupled so as to be rotated by the support bolt 138 to both sides of the loading box 107 so that the loading box 107 in an upright position,

A wire 135 having one end coupled to the pedestal 137 together with the elastic member 136 so as to be folded by the pedestal 137;

A lever 131 to which the binding bolt 132 which binds the other end of the wire 135 is coupled;

The center bolt 133 is further provided to rotate one end of the lever 131 to the protruding piece 134 of the rear connecting pipe 103 so as to rotate the lever 131.

Then, the bottom surface of the loading box 107 to the lower side of the central axis of the front and rear wheels 116 and 109 coupled to the front and rear prevention zones 111 and 101 so that the center of gravity of the loading box 107 is located at the low center of gravity. Is located.

Referring to the operation of the present invention as described above is as follows.

The crop transport cart of the present invention is most suitable for mainly carrying and transporting crops produced in the fields where the dumps (141) such as melon, cucumber, and tobacco.

That is, since the front and rear wheels 111 and 109 are coupled to the front and rear of the loading box 107 of the present invention, as shown in Fig. 2, it is optimal to move the furrow between the two 141 in a stable state. will be.

First, in order to load the crop into the loading box 107, as shown in Figures 1 and 2, the wagon of the present invention is placed between the ridge 141.

In this case, the front and rear directions of the loading box 107 is supported by the front and rear wheels 116 and 109 coupled to the front and rear prevention zones 111 and 101 of the loading box 107 and the loading box 107. The left and right directions of the support box 137 is coupled to the left and right sides of the loading box 107 by the support bolt 138.

Accordingly, since the loading box 107 is maintained in a stable state, the loading box 107 may be loaded without considering the load distribution of the crops loaded into the loading box 107, thereby enabling more rapid loading.

In a state in which a certain amount of crops are loaded in the stacking box 107 as described above, the cart should be moved to a vehicle or the like located in a warehouse or a field edge. In this case, the lever 131 coupled to the rear connection pipe 103 To fold the base 137, which was supporting the left and right sides of the loading box 107, must first be folded.

That is, when the lever 131 is placed from the solid line position as shown in FIG. 10 to the virtual line position, the lever 131 is centered on the center bolt 133 coupled to the protruding piece 134 of the rear connecting pipe 103. While rotating to pull the wire 135 which is binding the other end to the binding bolt 132.

In addition, one end of the wire 135 pulls the support 137 while compressing the elastic member 136 by the pulling phenomenon of the wire 135, and the support 137 of the loading box 107 is supported by the support bolt 138. 10) is rotated from the solid line position of FIG. 10 to the virtual line position to maintain the lifted state.

In addition, the compressed elastic member 136 is relaxed by the operation of mounting the lever 131 to the original position after the completion of transportation to rotate the pedestal 137 to the original position to support the pedestal 137 is loaded (107) It becomes possible.

As described above, in the state of folding the pedestal 137 on both sides of the stacking box 107, the operator grasps the handles on both sides of the rear connecting pipe 103 and pushes the wheelbarrow by the rotation of the front and rear wheels 116 and 109. It can be easily moved along.

At this time, since the front and rear wheels 116 and 109 are supported by the front and rear loads of the loading box 107, the operator adjusts only the load applied in the left and right directions by hand force. Give it a smooth conveying work.

Particularly, since the bottom surface of the loading box 107 is located below the central axis of the front and rear wheels 116 and 109 coupled to the front and rear prevention zones 111 and 101, the center of gravity is located at the low center of gravity. The load acting in the right direction can be easily adjusted with less force.

On the other hand, when the bent furrows appear during the movement along the furrows or curves, etc., the direction of the cart should be changed. In this case, the direction can be easily adjusted by the operation of the rear connection pipe 103.

That is, when the rear connecting tube 103 is rotated in a desired direction, as shown in FIG. 5, the rear connecting tube 102 and the driving pulley 104 coupled thereto rotate, but the rear support 101 is the rear connecting tube. Because it is connected to 102 and the bearing, it does not rotate.

In addition, by the rotation of the drive pulley 104, the transmission member 105 fixed to the drive pulley 104 by the rear high information bolt 106 is also rotated.

In addition, the transmission member 105 is rotated while being guided by a plurality of auxiliary pulleys 108 arranged to the outside of the loading box 107, the rotational force is driven driven pulley 113 coupled to the front connection pipe (112) Is delivered up to).

That is, since the driving member 105 is fixed to the driven pulley 113 by the front height information bolt 114, when the driving pulley 104 rotates, the driven pulley 113 also moves in the same direction as the driving pulley 104. It will rotate.

When the driven pulley 113 is rotated as described above, as shown in FIG. 6, the front connecting pipe 112 and the front support 111 integrated with the driven pulley 113 are also the same as the rotation direction of the driven pulley 113. Since it rotates so that the front wheel 116 can be rotated as shown in FIG.

Therefore, the front wheel 116 is moved in a state capable of steering, and the rear wheel 109 is not able to steer, so the front wheel 116 moves along the trajectory that the front wheel 116 draws, so that the direction is easily changed. will be.

On the other hand, when loading crops in the loading box 107 or when the present invention cart is stored in a warehouse, etc., the rear connection pipe 103 protrudes upwards, and thus has a problem of occupying a lot of distance or space.

In the present invention, to solve this problem, the rear connection pipe 103 is considered to be folded as shown in FIG.

The connecting piece 121 of the rear connecting pipe 103 is coupled to the fixing bracket 127 of the rear connecting pipe 102 by the central axis 122, so that rotation is possible.

In addition, the locking shaft 124 coupled to the coupling piece 123 of the rear connecting pipe 103 has a flat part formed on both sides thereof, and the supporting piece 125 of the rear connecting pipe 102 allows the flat part to pass therethrough. ), A locking hole 126 is formed.

That is, as shown in FIGS. 7 to 9, both planar portions of the locking shaft 124 are passed through the inlet of the locking hole 126 of the support piece 125, and then the locking shaft 124 is rotated about 90 °. It is locked and the rear connecting pipe 103 and the rear connecting pipe 102 are positioned in a straight line.

On the contrary, when the locking shaft 124 is separated from the locking hole 126 in the reverse order as described above, the rear connection pipe 103 is folded and rotated about the central shaft 122, so that the crop is convenient and stored. Even though it takes up less space, it can be stored.

On the other hand, the front connection pipe 115 shown in Figure 1 is used when moving the wagon of the present invention to the warehouse without the usual use.

That is, in a state in which the rear connection pipe 103 is folded in order to store the cart as a warehouse, it is not necessary to hold a part of the cart by the worker's hand.

At this time, the front connecting pipe 115 of the present invention is coupled to the front connecting pipe 112, the front connecting pipe 115 can be held in the warehouse by pushing the wheelbarrow by hand.

Of course, when the storage of the cart is completed, the front connection pipe 115 is separated from the front connection pipe 112 and put in the loading box 107, the next use becomes convenient.

In addition, the wagon of the present invention is mainly used for transporting crops, but can be usefully used for transporting fertilizer such as barns, manure transport, and compost.

In this way, the present invention is carried out in a balanced state while supporting the load acting on the front and rear of the loading box by the front and rear wheels, so that it is possible to transport crops in a very stable state without fear of overturning and to load the crops. In the stopped state, the pedestal supports both sides of the loading box so that crops can be loaded in a stable state without falling to the left and right sides, and the front wheel is steered by the rotation of the rear connection pipe to guide the rear wheels. It is possible to change the direction with little force even when a lot of crops are loaded on the ground and to fold the rear connection pipe which is combined with the rear connection pipe to prevent the jam when loading the crop and to keep it in small volume when storing. And the front connecting pipe coupled to the front connecting pipe can be separated and combined, It can be easily used and has a useful effect that the bottom surface of the loading box can be easily loaded and transported with a large amount of weight with low force by the low center of gravity design, which is lower than the center line of the front and rear wheels.
