Because whole tubular connection becomes box-like by the side plate of several drawings with a base plate assembly welding, not only make tubular connection solid, the outward appearance magnificence, be connected transition nature between arm-rest frame and the gearbox, link up, the profile of whole mini-size tillage machine is coordinated more, but also made full use of the bigger intracavity space of tubular connection, and take off top cover, the box-like space in the tubular connection can be used to deposit the instrument and the foreign material of some.Tank filler sleeve on the base plate is used for apply oil in gearbox.
Link to each other for the end face tooth cooperates between above-mentioned tubular connection and the arm-rest frame, the junction between tubular connection and arm-rest frame is provided with retaining mechanism.Adopt this structure, can easily realize that the height of arm-rest frame is regulated, make the workman realize stronger controlling mini-size tillage machine according to operator's height, easy to operate, laborsaving, be not easy fatigue.
The bolt hole that is used for connecting gear box casing on the above-mentioned tubular connection base plate is arranged in the box, and be positioned at tank filler sleeve around, connecting bolt is ensconced box inner region on the base plate, make the outward appearance of junction more succinct, good-looking.
Above-mentioned tubular connection back side panel is provided with and is used for gear shift lever is carried out spacing gear locating slot, and gear shift lever one end links to each other with declutch shift shaft in tubular connection, and declutch shift shaft one end passes behind the base plate with gear shift fork in the gearbox and is connected.After gear shift put in place, the gear shift lever card was limit in the gear locating slot, made it reliable location and did not go here and there.Gear shift lever links to each other in tubular connection with declutch shift shaft, makes whole mini-size tillage machine outward appearance seem more succinct.
The beneficial effects of the utility model are: the connective stability between arm-rest frame and the gearbox is good, and the outward appearance magnificence is solid, junction transition nature, coordination, and it is more convenient, laborsaving to control mini-size tillage machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that tubular connection 3 removes perspective view behind the top cover 14 in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, between mini-size tillage machine arm-rest frame 1 and gearbox 2, be provided with cross section and be squarish and pass through and increase thick tubular connection 3 gradually, tubular connection 3 is linking to each other with gearbox 2 housings after than the butt end bending, the end that tubular connection 3 links to each other with arm-rest frame 1 tilts to the back upper place, the upper end size basically identical than butt end and gearbox 2 of tubular connection 3.
Can find out that from Fig. 1, Fig. 2 tubular connection 3 is the box-likes that formed by side plate and base plate assembly welding, base plate 10 links to each other with gearbox 2 housings by bolt, also is provided with the tank filler sleeve 11 that communicates with gearbox 2 inner chambers on the base plate 10, and this tank filler sleeve 11 is blocked by plug screw 12; The upper side of tubular connection 3 is uncovered, and open-mouth is equipped with top cover 14 by bolt 13.Because whole tubular connection 3 becomes box-like by the flat lateral plate of several drawings with a square floor assembly welding, not only make tubular connection 3 solid, the outward appearance magnificence, be connected transition nature between arm-rest frame 1 and the gearbox 2, link up, the profile of whole mini-size tillage machine coordinated more, but also made full use of the bigger intracavity space of tubular connection 3.The box-like space that tubular connection is 3 li can be used to deposit the instrument and the foreign material of some.Tank filler sleeve 11 on the base plate 10 is used for apply oil in gearbox.
Link to each other for the end face tooth cooperates between tubular connection 3 and the arm-rest frame 1, the junction between tubular connection and 3 arm-rest frames 1 is provided with retaining mechanism.3 liang of symmetrical sides of tubular connection are provided with via hole 3a, and the welding of the outer end of via hole has between the inner of hollow knuckle-tooth piece 4, two via hole 3a of end face tooth and is welded with bushing pipe 5; Hollow knuckle-tooth piece 6 on the arm-rest frame 1 and 4 engagements of the hollow knuckle-tooth piece of via hole 3a outer end; Retaining mechanism is made of stay bolt 7 and lock nut 8, and stay bolt 7 passes the hollow knuckle- tooth piece 4 and 6 that is meshed, via hole 3a and the bushing pipe 5 on tubular connection 3 sides, and lock nut 8 is contained in stay bolt 7 ends with fixing between arm-rest frame 1 and the tubular connection 3.In the time need regulating to the height of arm-rest frame 1, lock nut 8 comes loose, hollow knuckle- tooth piece 4 and 6 between arm-rest frame 1 and the tubular connection 3 is withdrawed from engagement, the center of arm-rest frame 1 with hollow knuckle- tooth piece 4 and 6 rotated to an angle, allow hollow knuckle- tooth piece 4 and 6 mesh again then, screw lock nut 8 at last and get final product.5 pairs of stay bolts of bushing pipe, 7 guiding have the effect of support reinforcing again.Be handled easily, all-in-one-piece is connected with handle 9 on the lock nut 8.
