Detailed Description
The present invention will be further explained with reference to the accompanying drawings and specific embodiments:
detailed description of the preferred embodimentsfigure 1 shows a rake device with shallow ploughing function, comprising a transverse shaft 1 and rake teeth 2 mounted on the transverse shaft 1, wherein the root of the rake teeth 2 is welded on a cross beam 3, and the key points are as follows: the scraper knife device comprises a scraper knife rest 4 and a scraper knife 5, the scraper knife rest 4 is fixedly arranged in front of the cross beam 3, and the scraper knife 5 is fixedly arranged below the scraper knife rest 4; the connecting device comprises a suspension bracket 6 which is arranged above the scraper knife rest 4 and is fixedly connected with the scraper knife rest 4.
The rake device is used on agricultural machinery, the suspension bracket 6 is connected with a hydraulic rod of the agricultural machinery, the lifting and descending effects are achieved through hydraulic driving, the suspension bracket 6 is fixedly connected with the scraper frame 4, the scraper frame 4 is fixedly connected with the cross beam 3, and the three parts simultaneously lift or descend to achieve the synergistic effect; when using, lift through the adjustment hydraulic stem makes tine 2 be located the soil surface, the agricultural machinery starts to go forward, scraper knife 5 contacts with soil block stone on soil surface earlier, shovel into the fritter with comparatively loose soil block, soil block and stone that can't shovel are pushed away by scraper knife 5 and are followed the agricultural machinery travel direction and roll, 2 rake teeth behind scraper knife 5 are with the straw on soil surface, weeds and plastic film etc. play, scraper knife 5 is pushing away and is advancing such as stone, reduce tine 2 and soil block, the contact of stone, thereby reduce the pressure that it bore.
As shown in fig. 1, the blade holder 4 includes a first cross bar 4-1 and a second cross bar 4-2 arranged in parallel, and a connecting rod 4-3 connecting the first cross bar 4-1 and the second cross bar 4-2, wherein a row of blades 5 is fixedly installed below the first cross bar 4-1 and the second cross bar 4-2, the two rows of blades 5 are arranged in a staggered manner, and the second cross bar 4-2 is hinged to the cross bar 3.
Two rows of scraper knives 5 are respectively fixed below the first cross rod 4-1 and the second cross rod 4-2, and the two rows of scraper knives 5 are arranged in a staggered mode, so that the more intensive cultivation can be carried out on the surface of the land.
As shown in figure 1, the suspension bracket 6 is splayed and fixedly connected to the first cross rod 4-1, and a fixing rod 7 is further arranged between the suspension bracket 6 and the second cross rod 4-2.
