Description

[Detailed description of the invention] [Field of industrial application] The invention is applicable to a riding-type fertilizer application machine, a fertilization rice transplanter,
The present invention relates to a mounting structure for a fertilizer tank in a riding-type fertilizer application machine such as a fertilizer seeding machine.

[Problems to be solved by the prior art and the invention] Conventionally, in this type of riding-type fertilizer applicator, the fertilizer tank was installed on the side of the driver's seat, so the fertilizer tank was inevitably located at a high position. As a result, the center of gravity of the machine becomes high and the balance of the machine deteriorates, and the fertilizer tank gets in the way, making it impossible to provide a spare seedling stand, for example. Therefore, it is proposed to arrange the fertilizer tank at the front of the aircraft, but in this case, when installing the fertilizer tank, the support stay 25 should be extended laterally from the engine frame 15, as shown by the imaginary line in FIG. , it is conceivable to attach the fertilizer tank 8 to this. However, in this case, the support stay will be located below the step leading from the driver's seat, so this will get in the way, narrowing the space below the step and complicating the piping from the fertilizer tank. However, there is a problem in that the installation space for various attachments such as a car wash pump cannot be effectively secured and they become a nuisance.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a mounting structure for a fertilizer tank in a riding fertilizer application machine that can eliminate these drawbacks. In a riding-type fertilizer applicator in which a fertilizing section for applying fertilizer is provided to a riding-type traveling body, when a fertilizer tank is disposed at the front of the traveling body, the fertilizer tank is attached to the frame structure of the traveling body. The device is characterized in that it is configured to be connected and attached to the front end of the body and the side edge of the step portion continuing from the operation control portion.

With this configuration, the present invention allows the fertilizer tank to be placed at the front of the machine without the support stays interfering with the steps above and below.
Moreover, it can be installed firmly.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a traveling body of a riding-type fertilizing rice transplanter, and at the rear of the traveling body 1, planted seedlings placed on a seedling platform 2 are placed at the timing of the traveling speed of the machine. A working part 3 that performs the operation of scraping and planting on the rice field is provided so as to be able to move up and down via an elevating link mechanism 4. A nozzle 6 is provided. By driving the fertilizer pump 7, the fertilizer in the fertilizer tank 8, which will be described later, is applied from the fertilizer application nozzle 6 to a substantially predetermined depth within the field. Here, 9 is a detection sensor that detects the discharge state, 10 is a reducer that transmits power to the fertilizer pump 7 in a decelerated state, 11 is a sub tank, 12 is an engine installed at the front of the machine, and 13 is a transmission. be.

The fertilizer tank 8 is arranged on both left and right sides of the front part of the traveling machine body 1, and is made of hard plastic such as polyethylene, polypropylene, polystyrene, etc., and has brackets 8a, 8b on both the front and rear sides. protrudes like a flange. On the other hand, 14 is a bumper provided in front of the engine frame 15 and constitutes a part of the frame structure, and 16 is a step section continuing from the operation control section 17, which is located at both left and right ends of the bumper 14. One end portions of connecting stays 18 and 19 are integrally fixed to the side edges of the step portion 16 and the step portion 16. That is, a bracket 18a at one end of a substantially U-shaped connecting stay 18 is fitted to both left and right ends of the bumper 14 so as to sandwich the bumper 14, and is integrally fixed with bolts 18b. One end of a connecting stay 19 is integrally fixed to the side edge of the portion 16 with a bolt 19a. The other ends of these connecting bodies 18 and 19 are integrally fixed to the brackets 8a and 8b of the fertilizer tank 8, and in this way, the fertilizer tank 8 is connected to the bumper 14 and the step part 16. In this case, the load of the fertilizer tank 8 (for example, the load when filled with paste fertilizer) is mainly supported on the bumper 14 side. , which is designed to provide the necessary mounting strength. The fertilizer tank 8 thus installed on both left and right sides of the front part of the machine body has a pipe 20 that reaches the fertilizer pump 7 through the bottom surface of the step.

In the embodiment of the present invention configured as described above, the fertilizer tank 8 is disposed at the front of the machine,
The fertilizer tank 8 is attached to the bumper 14 and the step part 16, although a space for installing a spare seedling stand etc. can be secured on both left and right sides of the rear side of the driver's seat 17. Therefore, even if the fertilizer tank 8 is attached to the front of the machine, there is no need for the stay to protrude from a frame member such as the engine frame in an obstructive arrangement located below or above the step section. Therefore,
The space below the step portion 16 is secured as it is, and in this space, not only necessary parts such as the piping 20 but also attachments such as the car wash pump 21, the power steering cylinder 22, the power steering pump 23, etc. The mounting space for the members can be effectively secured, and the step portion 16 does not become narrow.

Moreover, the fertilizer tank 8 has a kind of rigid structure attached to the bumper 14, which is a member with extremely high strength.
Furthermore, it is possible to support the step part 16 with a structure in which the load of the fertilizer tank 8 is hardly applied to the step part 16. Therefore, the load on the step part 16 is small. 16 can be reinforced by the bumper 14 in a structure in which the fertilizer tank 8 is interposed, and the chattering phenomenon caused by vibration of the step part 16 can be eliminated, and noise can be reduced.

[Function and Effect] In summary, the present invention is constructed as described above, and although the fertilizer tank is arranged at the front of the aircraft, the fertilizer tank is located between the front end of the frame structure and the side of the step section. As a result of being connected and attached to the edge, the connecting stay is not located on the top or bottom of the step and becomes an obstruction, and therefore, a wide step surface is secured for the operator. In addition, the space below the step section does not become narrow.
It is possible to reliably secure space for accommodating various attachment members, not just the piping from the fertilizer tank. Moreover, the side edges of the step section are connected to the frame structure via the fertilizer tank, which eliminates the chattering phenomenon of the step section due to machine vibration, making it quiet with less noise. become.
