Description

[Detailed description of the invention]

[00013

[Industrial Application Field] The present invention relates to a rice transplanter, and more specifically, a seeding device or a weeding device that replaces the seedling planting device attached to the rear end of the lifting tank of a riding type rice transplanter, and furthermore, The present invention relates to a hitch for connecting a working device to which a working device such as an insect repellent device can be attached. [00023] [Prior Art] In the conventional riding type rice transplanter, only a seedling planting device could be connected to the rear end of the lifting link. [0003] [Problems to be Solved by the Invention] Rice transplanters are used only a few days a year, and their operating rate is low, so in recent years, versatility has been desired. [00043] An object of the present invention is to provide a hitch for connecting a working device that can easily attach working devices such as a seeding device, a weeding device, and an insect repellent device to a conventional rice transplanter. [0005]

[Means for Solving the Problems] A characteristic configuration of the present invention for achieving the above object is a hitch for connecting a working device that is attached to a hitch for connecting a seedling planting device at the rear end of a lifting link of a riding type rice transplanter. a hitch body that is attached to and detached from the hitch for connecting the seedling planting device; a hitch portion for connecting the working device that is rollably attached to the hitch body; and a hitch for connecting the working device to the hitch body. The present invention is characterized in that a hitch for connecting a working device is provided, which is comprised of an adjusting device for adjusting the rolling limit angle of a portion, and its functions and effects are as follows. [0006]

[Operation] When installing a weeding device in place of the seedling planting device, as shown in Fig. 4, attach the working device connecting hit H to the seedling planting device connecting hit C, and connect the working device connecting hit H to the seedling planting device connecting hit C. Connect hitch K on the weeding device side to H. (0007]

As a result of the above structure, a working device such as a weeding device can be attached by attaching the working device connecting hitch to the seedling planting device connecting hitch, and the working device connecting hitch The rolling limit angle of the work equipment can be adjusted by the adjustment device, or it can be made impossible to roll by using the adjustment device, so it is suitable for seeding equipment and weeding equipment that require rolling, and insect control equipment that does not require rolling. It is possible to attach various working devices such as, increasing the versatility of the rice transplanter. [00081] [00081] Examples of the present invention will be described below based on the drawings. [0009] As shown in FIG. 6, a traveling aircraft A includes an engine 1, a control handle 2, and a pair of left and right front and rear wheels 3 and 4.
A seedling planting device B is connected to the rear part of the seedling planting device B via a link mechanism 6 that is driven up and down by a hydraulic cylinder 115. [00101 As shown in FIG. 5, the seedling planting device B includes:
The hook 7 of the hitch C at the rear end of the link mechanism 6 is engaged with the hole 9 of the hitch D on the side of the seedling planting device B, and then the seedling planting device B
The hooks 8a, 8a of the locking mechanism 8 of the hitch C on the link mechanism 6 side are engaged with the pins 10, 10 of the hitch [) on the side, and are fixedly connected. [0011,] Next, a hitch for connecting a working device that is attached to the hitch C for connecting the seedling planting device when a working device such as a weeding device is attached in place of the seedling planting device Ai will be described. [0012] As shown in FIGS. 1 to 3, the working device connecting hitch H is a working device that is rollably attached to the hitch body E fixed to the seedling planting device connecting hitch C. It consists of a connecting hit part F and an adjusting device G that adjusts the rolling limit angle of the working device connected to the working device connecting hit part F. [0013] The hitch main body E includes the hook 7 of the hitch C for connecting the seedling planting device, and the hook 8a of the locking mechanism 8. 8a, and a cylindrical body 15 fixed to the plate body 13 through the plates 1 and 1 in the front-rear direction. Also, the working device connection hitch portion F includes a shaft 16 inserted into the cylindrical body 15, a working device connection box 17 integral with this shaft ]-6, and a work device connection box 17 integral with this box 17. The adjusting device G includes a pair of left and right regulating plates 18.18, and the adjusting device G includes a pair of left and right bolts 19.
It consists of 19. [0014] Further, the hitch main body E is provided with another working device connection fixing hit (2) to which a working device that does not require rolling, for example, a working device such as an insect repellent device, can be connected. Further, a pair of left and right pipe frames 20, 20 to which tail wheels can be attached are fixed to the working device connection box 17. [0015] The working device connecting hitch H has a contact plate 21 at the tip of the shaft 16 protruding from the cylindrical body 15 with respect to the hit body E, which abuts against the pair of left and right regulating plates 18, 1.8.
is fitted onto the outside, and its backing plate 2 is fixed to the pair of left and right regulating plates 18.18 via a nut 22 screwed onto the tip of the shaft 16 and a pair of left and right bolts 23.23. ■It is connected to Noh. [0016] Next, the weeding device as a working device attached to the working device connecting hit F ( will be explained. As shown in FIG. 4, the weeding device J is a weeding wheel supported in a freely rotating state. It consists of a body 24, a pushing tool 25 made of a bar for pushing weeds in advance in advance of the operation by the ring body 24, and a groove cutting tool 26 for forming a drainage groove in front of the transport body 24, The work equipment connection hitch ■1
It is equipped with a hitch K that is connected to. [0017] As shown in FIG. 7, when the tail ring is attached to the pipe frame 20 of the work equipment connection box 17, that is, when the cultivating soil device etc. are attached to the work equipment connection hitch F1, the tail wheel The tail ring will be installed, but the position of the lateral tail ring can be changed, and the position can be maintained by a locking mechanism 27 using a spring-loaded locking pin. . [0018] The working equipment is not limited to weeding equipment and soil cultivation equipment, but also includes various attachments for seeding equipment and insect control equipment.
~ are connected. [0019] In addition, an insect control device or the like that does not require rolling can be connected to a rollable work device connection hitch portion without being connected to a fixed hitch, and can be made non-rollable by an adjustment device. [00203 Furthermore, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the attached drawing A.
