Field of the Invention The present invention relates to a rice transplanter having a spraying device such as a chemical spraying device, and more particularly to a rice planting device provided at a rear end of a seedling planting section. The technology relates to a technique for shortening the overall length of a rice transplanter without affecting function. 2. Description of the Related Art A spraying apparatus having a hopper for storing objects to be sprayed and a spraying mechanism for spraying the objects to be sprayed from the hopper to a field is provided from a lower end of a seedling table. Japanese Patent Application Laid-Open No. 8-308323 discloses a rice transplanter with a spraying device, which is provided behind a seedling planting mechanism for cutting and transplanting seedlings to a field.
What is shown in the gazette is known. In this rice transplanter, a fertilizer application device consisting of a fertilizer hopper and a feeding mechanism is arranged on the rear side of a seedling mounting table, and further equipped with a chemical spraying device on the rear side of the fertilizer device, and after the seedlings are transplanted. It was configured so that the medicine could be sprayed well on the field. [0003] A rice transplanter has a structure in which a seedling planting portion, which is a heavy load, is supported rearward of the fuselage via an elevating link mechanism. Work machine. Therefore, if a spraying device or the like is provided on the rear side of the seedling planting portion in an overhanging state, the rear balance becomes stronger, and the balance weight to be attached to the front end of the aircraft needs to be heavier. There has been an inconvenience that the weight becomes heavier and the disadvantageous situation for the rice transplanter becomes noticeable. In addition, since the amount of rearward protrusion from the rear wheel, that is, the rear overhang, becomes considerably large, there is a disadvantage that it is difficult to turn or back, and there is room for improvement in the rice transplanter with the chemical spraying device. It was something. [0004] An object of the present invention is to devise a spraying device.
The point is that the overall length as a rice transplanter can be shortened to improve rearward balance. [0005] [0006] [0007] [0008] [0009] [0010] [0011] [0012] [Means for Solving the Problems] [Configuration and operation] of claim 1 configuration, storing the object to be sprayed was A seedling plant that cuts out seedlings from a lower end of a seedling mounting table and transplants the seedlings into a field. In a rice transplanter with a spraying device that is configured to be freely deployable on the rear side, a seedling table for storing a plurality of seedlings can be separated from a main seedling table part and a separate seedling table that can be separated from the main seedling table part. And an operating posture in which the separated seedling mounting part is connected to the lateral side of the main seedling mounting part, and a storage attitude in which the separated seedling mounting part is positioned so as to overlap above the main seedling mounting part. Receiving member that is configured to be freely switchable and that supports the separated seedling mounting table in the storage position Is provided at the lower end of the main seedling platform in a state protruding in a direction substantially orthogonal to the seedling mounting surface of the main seedling platform, and the receiving member is retracted with its rear end positioned toward the main seedling platform. It is characterized by being configured to be switchable between a state and a reference state that does not approach the main seedling mounting table side. According to a first aspect of the present invention, there is provided means for realizing the forward arrangement of the spraying device in a structure having a structure for reducing the lateral width of the seedling mounting table. That is, at the time of planting work, the separated seedling mounting part is switched to the working posture connected to the lateral side of the main seedling mounting part, and at the time of non-operation such as mounting a truck, the separated seedling mounting part is moved to the main seedling mounting part. It is switched to a storage position in which the entire width of the seedling mounting table is narrowed by being positioned so as to overlap the upper part of the section. For this purpose, a receiving member for mounting and supporting the separated seedling mounting portion in the storage position is attached to the lower end portion of the main seedling mounting portion so as to protrude in a direction substantially orthogonal to the seedling mounting surface of the main seedling mounting portion. Since the rear end position of the receiving member can be switched between the retracted state in which the rear end position of the receiving member is shifted toward the main seedling mounting table side and the reference state in which the rear end position is not shifted toward the main seedling mounting table side, the retracting state is provided when the spraying device is equipped. In this state, the amount of protrusion of the receiving member upward and rearward can be shortened, and the spraying device can be arranged as close to the front as possible. Since the spraying equipment is required during planting work,
Seedling platform is in working position. At the time of the non-planting operation, since the spraying device is not required, by removing the spraying device from the seedling planting section,
The receiving member can be returned from the retracted state to the reference state, thereby making it possible to switch to the storage position in which the lateral width of the seedling mounting table is reduced. In other words, it is possible to achieve both the adoption of the structure for reducing the width of the seedling mounting table and the arrangement of the spraying device closer to the front. According to the first aspect of the present invention, in the rice transplanter with the spraying device, the lower end portion of the main seedling mounting portion protrudes substantially perpendicular to the seedling mounting surface. The separation seedling mounting part is mounted on the receiving member provided in the, and the lateral width of the seedling mounting base can be reduced, while the attitude of the receiving member is changed according to the use situation, so that the spreading device is shifted forward. A rational one that can reduce the overall length of the fuselage and improve the rearward balance is obtained.
