なく安定して走行できる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting an auxiliary wheel detachably provided on a disk of a rubber wheel of an agricultural tractor. [0002] Various proposals have been made for an auxiliary wheel mounting device. For example, in Japanese Utility Model Publication No. 54-10332, a pair of cylindrical receivers and one cylindrical receiver are provided symmetrically on the main wheel side, and the auxiliary wheel side is disengaged from the pair of receivers. A pair of support pins and a slidable support pin that engages with and disengages from one receiver are provided, respectively, engaged and locked to easily attach and detach the auxiliary wheel to and from the main wheel. [0003] The above-mentioned auxiliary wheels have an appropriate clearance between the receiving metal and the support pins in order to facilitate the mounting, so that a slight backlash occurs. Equipped with the auxiliary wheel of this invention and introduced to Nagata's scraping work, earth and sand entered the receiver and the support pin, and it was worn due to repeated tataki phenomenon in mud, and the receiver was damaged in pursuit There was a problem that it became difficult to use page (2). [0004] In order to solve the above problems, a pair of receiving members (2, 2) and one receiving member are mounted on a disk (1) of a rubber wheel (b) mounted on an agricultural tractor. The metal (3) is provided at a symmetrical position, and an annular mounting metal (10) provided on one side of the auxiliary wheel is provided with a supporting metal (12, 12) which engages with the pair of metal receiving members (2, 2). A locking pin (1) provided with a stopper (15) that engages with the one receiver (3).
6) is mounted by being supported on a case (14) fixed to the mounting metal (10), and the pair of receiving metal (2, 2) and the supporting metal (12, 12) are mutually tapered. Locking and fitting of one receiving member (3) and a stopper (15) of the engaging and disengaging pin (16) in a tapered shape, and the engaging and disengaging pin (16) is provided with crimping means. The present invention provides an auxiliary wheel mounting device for an agricultural tractor, characterized in that a stopper (15) is locked and attached to a receiver (3). As described above, the pair of receiving members and the supporting member are fitted and locked in a tapered shape, and one receiving member and the stopper of the engaging / disengaging pin are fitted in a tapered shape. Since the crimping means is provided, the auxiliary wheel can be easily and quickly attached to and detached from the main wheel, and in the attached state, the receiving metal and the support pin are appropriately crimped and fixed and do not play. Therefore, even if earth and sand enter, there is no backlash, so that the receiver does not wear, and a stable scraping operation can be performed. FIG. 1 is a cross-sectional view in which the present invention is implemented, FIG. 2 is an enlarged view of a main part, and (a) is a plan view. (B) shows a side view.
FIG. 3 is a perspective view of the connecting metal, and FIG. 4 is a lower perspective view of the mounting plate. A is a rubber wheel for agriculture in which a rubber tire is mounted on the peripheral edge of the disk 1 via a rim. The outer surface of the disk 1 has a cylindrical shape having a pair of U-shaped tapered outer surfaces. Ring-shaped connecting metal 4 in which the receiving metal 2, 2 and one cylindrical U-shaped tapering metal 3 having a taper are fixed at symmetric positions.
And a plurality of holes 5 formed in the connection metal 4 and the disk page (3) 1 are tightened and fixed with bolts 6. Reference numeral "b" denotes an auxiliary wheel mounted on a rubber wheel "a". Annular pipe rims 7 and 8 are concentrically arranged on the left and right sides, and hollow hermetically sealed lugs 9 are provided on their peripheral portions at appropriate intervals. An annular mounting metal 10 is arranged concentrically outside of and is fixed to the rim 7 by several arms 11. A mounting metal 10 is provided with a pair of support metals 12 which engage with receivers 2 provided on a connecting metal 4 fixed to a rubber wheel a.
12 and a metal fitting engaging with the receiving metal 3 are mounted at symmetrical positions. The support metal has a square fiber shape tapered toward the tip. Further, as shown in the enlarged views (a) and (b) of FIGS. 2A and 2B, one end of the locking metal is fixed to the mounting metal 10 by a case 14 having a rectangular frame. Reference numeral 15 denotes a stopper which has a shape conforming to the above-mentioned cylindrical and tapered receiving member 3, is connected to an engaging / disengaging pin 16, is inserted through the outer wall of the case 14, and
It is landed inward by 8. 13 is a cam plate and 1
7 is rotatably fixed by the support shaft 7 and is gripped and rotated by the lever 19 to push up the tip of the engagement / disengagement pin 16 against the spring 18 to cause the stopper 15 to protrude. It proceeds in the direction of the arrow and is fixed by pressure bonding to the receiver 4. When the stopper 15 is removed, when the lever 19 of the cam plate 13 is returned to its original position, the engaging / disengaging pin 16 is returned by the spring 18 and the stopper 15 comes off from the holder 3. Next, the auxiliary wheel b may be lifted gently to pull out the support metal 12 from the receiver 2. With the above construction, the auxiliary wheels can be quickly and easily attached to the main wheels of the tractor. Page (4) In addition, since the receiving metal and the supporting metal are fixed and crimped on the tapered surface,
Even in muddy soil such as Nagata's scraping work, it can run stably without rattling of the mounting part.
