The present invention relates to an auxiliary wheel that can be mounted on agricultural machinery (mainly agricultural tractors, tillers, etc.) to prevent the slip of the wheel during work.

The applicant of the present application filed an application for "Agri-machine auxiliary wheel" (application number: Utility Model Registration No. 7562, 1991) on May 27, 1991, and the present application is an improved form of agricultural machine assistance for the above-mentioned application. It's about wheels.

As shown in FIG. 1, the auxiliary wheel for agricultural machinery, which is filed by the applicant of the present application, has a circular fixing bracket 103 having several threaded holes 101 and engaging projections 102 so as to be mounted and used on the wheels of agricultural machinery. It is fixed to the support 104 and at the same time a plurality of pin holes 105, 105 ', 105 "in the longitudinal direction to secure a plurality of fastening tube 106 formed in a set, each fastening tube 106 in common triangular scaffold It is fixed to the bottom of the (107) at the same time the pin hole (108, 108 ', 108 ") is formed by inserting the connection pipe 109 is fixed to the fastening pin 110, characterized in that configured to be coupled to the fixing pin 111 Doing.

Such a prior application "Assistant wheel for agricultural machinery" is configured to be attached to the wheel of the agricultural machinery auxiliary and formed to adjust the size of the outer ring formed by fastening pins and fixing pins to provide the auxiliary wheel having a number of outer ring size of the conventional single shape Compared to the auxiliary wheels, it was a step forward in terms of strength and ease of use.

However, in addition to the advantages described above, the prior application was inherent in the following insufficient, looking at this;

1. Fastening of the fastening pipe 106 and the connecting pipe 109 by simply combining the fastening pin 110 and the fixing pin 111 on the pin hole (105 ... / 108 ...), in the actual use of the fastening pipe There was a closed end through which the connecting tube 109 flows within 106.

In order to solve the above problems in the working environment of agriculture, when the fastening pipe 106 and the connecting pipe 109 are configured to be tightly coupled, the soil is inserted and the insertion itself becomes impossible and a great deal of effort is made. Because of this, this close relationship is not possible. Therefore, a certain clearance is formed between the unavoidable fastening pipe 106 and the connection pipe 109, which acts as a factor that shortens the life of the product by causing noise and vibration during work.

2. Triangular scaffold 107 as shown in Figure 1 is composed of a right triangle on the front, which has a disadvantage that does not provide uniformity during the forward and backward work has been required to improve this,

3. It is natural that the auxiliary wheel should be larger in diameter than the wheels for farm machinery in operation. To this end, in the first application, the outer diameter of the auxiliary wheel is reduced by slide-in and fastening the connecting pipe 109, which is pin-coupled on the fastening pipe 106, and moved in this state. If the ground is uneven, the triangular scaffold 107 at the end of the connecting pipe 109, which is fastened in the center direction, is connected to the ground, which causes difficulty in progress with noise. This is especially important,

4. When manufacturing the shape of the fixing bracket 103 in a circular shape, there was a difficulty in manufacturing, which caused a price increase factor of the product. Therefore, it is not necessary to insist on the circular shape, so it is improved to various polygonal shapes to exclude the price increase factor. There was a need.

It is a main object of the present invention to provide an improved type of wheel for agricultural machinery that can supplement a number of problems as described above, which will be described in detail with reference to the accompanying drawings 2 to 3 below. Let's look at it.

2 is an exploded perspective view of a part of the auxiliary wheel 1 showing an embodiment of the present invention, the fixing bracket 2 constituting the auxiliary wheel 1 is composed of a polygon (here hexagon) to cancel the manufacturing difficulties On the fixing bracket (2), several fastening pipes (3, 3 ') are firmly mounted and fixed radially.

The fastening pipes 3 and 3 'are composed of several pin holes 4a, 4b, 4c and 4d on both sides. The pin holes 4b in the center will be described later, but the connection pipes 5 and 5' are used during work / movement. Perform a folding base.

The first pin hole 4a is a pin hole used at the time of folding, and the third and fourth pin holes 4c and 4d serve as adjustment holes for determining the outer ring size of the auxiliary wheel 1 at the time of work.

Two sides of the above-mentioned pin holes 4a, 4b, 4c, and 4d and pin holes that can be selectively blown into both sides of the connecting pipes 5 and 5 'that can be inserted into or removed from the fastening pipes 3 and 3'. 6a, 6b, 6c) are formed.

The pin holes 4a, 4b, 4c, and 4d of the fastening pipes 3 and 3 'form female threads 4a' and 4b '. Fixing pins (8) and fastening bolts (9) assembled with the fastening pins (7) when fastening the connecting pipes (5, 5 ') on the fastening pipes (3, 3'). Of course, the fastening bolt 9 is screwed with the female threads (4a ', 4b' ...) formed in the pin holes (4a, 4b ...) of the fastening pipes (3, 3 '), the end of the fastening nut for a secure fastening It is preferable to screw (10).

Triangular scaffolds 11 and 11 'are integrally formed at the ends of the connection pipes 5 and 5', and the triangular scaffold is composed of an isosceles triangle unlike the prior art.

In the drawings, reference numeral 12 denotes a screw hole 13, and a coupling protrusion 14 denotes a support.

Let us look at in more detail with reference to Figure 3 the use state of the subject innovation constructed as described above.

3a illustrates a work state of the auxiliary wheel 1 of the present invention, which is a case where the auxiliary wheel 10 of the present invention is mounted on a wheel of an agricultural machine to perform work.

At this time, the triangular scaffolds 11 and 11 'at the ends of the connection pipes 5 and 5' are fitted into the outer diameter portion, and the second pin holes 4b and the fourth pin holes 4d on the fastening pipes 3 and 3 'are positioned on the connecting pipes 5 and 5'. The fastening pins 7 and fastening bolts 9 are fastened to correspond to the pin holes 6a and 6c of the connecting pipes 5 and 5 ', respectively.

Of course, one end of the fastening pin (7) is coupled to the fixing pin (8) for preventing the separation of the fastening pin (7), one end of the fastening bolt (9) is also fastening nut (10) is screwed. .

Figure 3b is another embodiment of the working state of the auxiliary wheel (1) of the present invention, when the ground is soft when the outer diameter of the auxiliary wheel (1) can be expanded to compensate for the driving force, in this case the fastening pipe The fastening pins 7 and fastening bolts 9 on the third and fourth pin holes 4c and 4d on the 3 and 3 'pins 6a and 6b of the connecting pipes 5 and 5', respectively. It is fastened to correspond with. That is, the outer diameter of the auxiliary wheel (1) is expanded than the first embodiment is used when the driving force is required in the deep, soft ground yarn.

3c and 4 show the case of moving the work space with the auxiliary wheel 1 of the present invention mounted on the wheel.

In this case, the triangular scaffolds 11 and 11 'of the connecting pipes 5 and 5' are rotated 180 ° in the center direction so as to be accommodated inside the fixing bracket 2. That is, the first and second pin holes 4a and 4b of the fastening pipes 3 and 3 'and the pin holes 6a and 6c of the connecting pipes 5 and 5' are formed as mutual fastening pins 7 and fastening bolts 9. When the fastening is fixed, the outer diameter of the auxiliary wheel (1) during the movement is minimized, so that even when the ground is uneven, the movement can be performed without any disturbing factor.

The fastening method of the connecting pipes (5, 5 ') as described above is made of two-point fastening, there is no squeaking or vibration, so that it has a superior fixing effect compared to the conventional single pin fixing, thereby improving the durability of the product.
