  The present invention solves the problems described in the background art, and is a straddle-type agricultural cart that can be easily operated in a sitting posture and can be manufactured at a low cost even in a relatively small field or kitchen garden. It is an issue to provide.

Means for solving the problems and effects of the device

The present invention has been conceived to make it possible to perform farming work while sitting on a seat plate mounted on a frame supported by four or more wheels.
That is, a straddle-type agricultural cart of the present invention (Claim 1) includes a rectangular frame elongated in the front-rear direction in a plan view, wheels attached to at least both sides of the frame in the front-rear direction, and an upper surface of the frame. A base erected from the vicinity of the center, a seat plate attached to the upper end of the post, a branch pipe extending in the horizontal direction from the middle of the post, and a horizontal base detachably attached to the branch pipe. And an L-shaped tube having a support portion at least one of the upper end and the middle of the vertical portion.

  According to this, since the seat plate is attached to the upper part of the frame supported by four or more wheels located in the front, rear, left and right via the support column, the operator sits on the seat plate in various states. Agricultural work can be done. Therefore, farm work such as weeding and harvesting vegetables or fruits can be easily performed by manual work at a relatively low position without burdening the waist and knees and without fatigue. Moreover, for example, a fan or a ceramic heater is fixed to the support portion of the L-shaped tube that is detachably attached to the branch tube extending in the horizontal direction from the middle of the support column. It is also possible to suppress the cold, and furthermore, it is possible to block rainwater and sunlight by fixing an umbrella (rain umbrella or parasol) to the support portion on the upper end side. Therefore, various farming operations can be performed easily and reliably without imposing a burden on the body and can be manufactured at low cost.

The frame is formed of a channel steel having a vertical or substantially square cross section, or an extruded shape of an aluminum alloy.
The seat plate is recommended to have a height of about 30 to 50 cm from the ground (the lowest part of the wheel). Therefore, the diameter of each wheel is recommended to be about 15 to 20 cm.
Further, the seat plate can be fixed to a plurality of sets of bolts and nuts with respect to a horizontal plate fixed to the upper end of the column, and can be fixed in a direction rotated 90 degrees (right angle) in plan view.

Further, the present invention includes a straddle-type agricultural cart (Claim 2), in which the branch pipe is fixed to a cylindrical body that is fitted to the support column so as to be turnable in the horizontal direction.
According to this, by rotating the cylindrical body at an arbitrary angle in the horizontal direction, an L-shaped pipe having a base detachably attached to a branch pipe rotated together with the cylindrical body has a problem in farm work for the operator. It can be placed in difficult positions. Therefore, by fixing the fan, heater, umbrella, transistor radio, portable information terminal, or the like to the upper or middle support portion of the vertical portion of the L-shaped tube, there is no burden on the body and the weather This makes it easier to carry out farming work.

Further, in the present invention, a pair of left and right brake plates that can come into contact with and separate from the peripheral surfaces of the pair of left and right wheels are horizontally disposed at one end in the front-rear direction of the frame. A straddle-type agricultural trolley that is connected to a U-shaped connecting piece in plan view, and a base end of the connecting piece is supported on both side surfaces of the frame so as to be pivotable along a vertical direction (Claim 3). Is also included.
According to this, when the front end portion of the connecting piece is lifted upward, the pair of left and right brake plates rises slightly together with the connecting piece, and comes into contact with the peripheral surfaces of the adjacent pair of wheels. As a result, since the pair of wheels are fixed, it is possible to prevent a situation where the cart for agricultural work begins to run inadvertently on an inclined land or a mountainous field. Therefore, even when the worker stands up as necessary, it is possible to perform farming while ensuring safety.
In addition, in order to keep the connecting piece lifted upward, the support tube is fixed horizontally on a handle fixed obliquely downward to the end of the frame, and an approximately oval ring is attached to the support tube. May be rotatably supported along the vertical plane, and the bottom of the connecting piece may be placed on the ring and fixed in position.

Further, according to the present invention, the support portion at the upper end of the vertical portion of the L-shaped member includes a pair of sandwiching plates that can be contacted and separated, and an umbrella handle is sandwiched between the pair of sandwiching plates. A type agricultural cart (claim 4) is also included.
According to this, the necessary agricultural work can be reliably performed while blocking rainwater and sunlight by sandwiching and fixing the handle of the umbrella (rain umbrella or parasol) between the pair of sandwich plates. Therefore, the desired farming work can be performed regardless of the weather. The umbrella includes, for example, beach umbrellas or straw hats.

Further, according to the present invention, an intermediate support portion in the vertical portion of the L-shaped member includes a base end portion that is supported so as to be pivotable along the horizontal direction with respect to the vertical portion, and a horizontal direction from the base end portion. A straddle-type agricultural cart (Claim 5) including an extended arm and a support base provided at the tip of the arm is also included.
According to this, it is possible to get cool in the summer by fixing the fan using a belt etc. on the support base, or to warm up in the severe winter season by fixing the ceramic heater, Agricultural work can be done comfortably regardless of the season.
For example, a transistor radio, a radio cassette, or a liquid crystal television can be fixed on the support base.
In other words, the present invention can also be a straddle-type agricultural trolley in which diagonally downward handles are fixed to both ends of the frame in the front-rear direction.
In this case, hook a finger or a string on the handle and move the agricultural cart together with the frame to a desired position (near the fence to be farmed next), or move to a tunnel for a break. It becomes easy. Alternatively, it may be used to tie a rope or the like for towing another cart carrying harvested products or weeds.
