Description

  The present invention relates to a transport cart and fertilizer spraying device capable of transporting various crops and materials for farming work and spraying fertilizers and chemicals on cultivated land.

  The cultivation of various crops includes a work for transporting seedlings and harvested crops and a work for spraying fertilizers and chemicals on the seedlings and crops.

  Conventionally, the work of transporting seedlings and harvested crops is labor-saving by using a transport cart that can travel across ridges and moving seedlings and harvested crops on the platform of this transport cart. I try to plan.

  Fertilizer and chemicals are sprayed manually using a manure or a fertilizer attached to a farming machine (a vehicle such as a tractor or cultivator) that travels in the groove between ridges by a driving source. Along with the movement and the traveling of the vehicle by itself, the fertilizer and chemicals stored in the hopper of the fertilizer application device and fertilizer applicator are quantitatively applied.

  As mentioned above, in the past, the work of transporting seedlings and harvested crops and the work of spraying fertilizers and chemicals were considered to be separate and independent work. A device or fertilizer machine was prepared.

  However, the transport cart is a mechanism that can only be used for transporting seedlings and harvested crops, so it has no versatility, and the annual operation time is limited, which is wasteful in terms of cost.

  In addition, in fertilizer application, fertilizer applied to tractors and cultivators cannot be applied across ridges. Since it runs in the groove, there is a possibility that it may fall over in an unstable running, and there is a problem that workability is poor.

  Therefore, the problem of this device is to select both a transport cart and a fertilizer applicator, so that both the functions of the transport cart and the fertilizer spreader can be combined, which not only saves money but also travels across ridges. An object of the present invention is to provide a transport cart / fertilizer application device capable of stable fertilization.

  In order to solve the above-mentioned problems, the present invention is directed to a transport cart that can travel across ridges by driving a wheel by a power source provided on the frame, and a fertilizer that is fixed to the frame of the transport cart so as to be removable. It consists of a machine, and can carry out selectively the carrying work by single use of the carrying carriage and the fertilizing work by attaching a fertilizer machine to the carrying carriage.

  The transport cart is provided with a transmission and a rotation transmission mechanism for interlocking the transmission and the wheel, the fertilizer attached to the transport cart is interlocked with the transmission via the rotation transmission means, and the fertilizer is transported. By driving with the wheel rotational force, the amount of fertilizer and medicine sprayed may be kept constant even when the traveling speed of the transport cart changes.

The fertilizer applicator can also drive the fertilizer application mechanism with a motor. in this case,
A mechanical drive mechanism from the axle of the carriage is not required, and the motor rotation speed control for setting the spraying amount can be adjusted by rotating operation of a knob or the like provided in the control box.

  Further, in the fertilizer applicator, the transport cart is provided with a vehicle speed detection sensor for detecting wheel rotation, and a control mechanism for controlling the motor of the fertilizer spreading mechanism by a vehicle speed detection signal from the vehicle speed detection sensor. It is also possible to adopt a structure in which the control mechanism controls the motor in accordance with the speed so as to control the amount of fertilizer and medicine sprayed.

  Here, the transport cart is provided with leg members at the front and rear positions on both sides of a rectangular loading platform in which a plurality of horizontal bars are arranged side by side to form a frame. The crossbar can be removed, and the wheel attached to the lower part of the leg member is driven by a power source attached to the leg member.

  The loading platform of the frame in the carriage is formed in a rectangular shape with a length that can cross the ridges, using a metal square pipe, fixing a plurality of horizontal bars between the side members on both sides at regular intervals. The grip is fixed to the horizontal beam bar located at the rear part in the running direction, and the horizontal beam bar located at the front part in the running direction is fitted with both ends into an upward U-shaped holder fixed to the side members on both sides, It is detachably attached with pins and bolts.

  The side members on both sides are fixed with leg members extending downward at the front and rear positions, wheels are attached to the lower ends of the leg members, and the front wheels or rear wheels on both sides are clutched by an engine or motor as a power source. It is possible to change the traveling direction by controlling on / off of the clutches on both sides with the lever of the grip.

  Further, the step is fixed to the leg member located at the rear part in the traveling direction, and the worker can move on the step during the transportation work or the fertilization work.

  The fertilizer applicator has a hopper for storing fertilizer and a fixing bracket for the horizontal bar of the loading platform. The fertilizer application mechanism of the fertilizer applicator is provided with a roll at a lower discharge port portion of the hopper, A roll feeding system is adopted in which the fertilizer taken in the measuring recesses formed on the surface is discharged and spread by rotation.

  There are two methods for driving the fertilizer application mechanism roll: one is driven by the rotation of the wheels of the transport cart, and the other is driven by the motor operated by the power supply from the battery. The former is driven by the rotation of the wheels of the former transport cart. The method of taking is to obtain the rotation of the roll from the wheel of the carriage via the transmission, the rotation transmission mechanism and the rotation transmission means, and changing the reduction ratio of the transmission to change the rotation speed of the roll, Alternatively, the spray amount is adjusted by exchanging different rolls of the measurement recesses.

  In the latter method, the motor speed is set in accordance with the spraying amount and the carriage speed, and the information on the spraying amount and spraying width per area is set in the control mechanism. A method that can calculate the amount of fertilizer and chemicals corresponding to the traveling speed of the transport cart by calculating the spray rate from the vehicle speed detected by the detection sensor and controlling the rotation speed of the motor that drives the roll. There is also.

  The fixing bracket provided on the fertilizer applicator is located at the rear of the fertilizer application mechanism at the lower part of the hopper, fitted into the horizontal bar from above, and fixed by tightening the bolts. When installing the machine, remove the horizontal beam bar located at the front and fix it to the horizontal beam bar located second from the front, preventing the fertilizer machine from protruding greatly in front of the transport cart and making the whole bulky At the same time, the overall center of gravity can be stabilized.

  According to this device, a combination of a self-propelled transport cart and a fertilizer machine that is detachably fixed to the transport cart allows the transport cart to be used as it is for transporting seedlings and harvested crops. If the machine is installed, it becomes a fertilizer spreader, which can carry out transport work and fertilizer work with one transport cart, and it is multi-functional by combining the transport cart and fertilizer applicator, and the transport cart and fertilizer spreader are separated Costs can be reduced compared to the case of preparing for the above.

  In addition, since the transport cart also serves as a part of the fertilizer spraying device, it can travel across the ridges that are impossible with an agricultural machine (tractor, tiller), and can perform stable fertilizer application and fertilizer spraying of the fertilizer applicator. By driving the mechanism according to the wheel rotation of the transport cart, the transport speed of the transport cart and the operation of the fertilizer spraying mechanism can be synchronized, and even if the travel speed of the transport cart changes, the fertilizer and medicine spraying is constant Can be kept in.
