Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the anti-blocking device of the seed and fertilizer discharge pipe of the present invention includes a movable tongue 5 for blocking the 7 nozzles of the seed and fertilizer discharge pipe. 1 There is a fixed frame lug 8 at the bottom, a movable tongue lug 9 is arranged on the movable tongue 5, the fixed frame lug 8 and the movable tongue lug 9 are connected by a fixed pin shaft 3, and the fixed pin shaft 3 is covered with a torsion spring 4. One end of the torsion spring 4 acts on the fixed frame 1, and the other end acts on the movable tongue 5. When the device is installed on a sliding opener, the seed and fertilizer discharge pipe 7 is used to receive seeds or fertilizer, and the fixing frame 1 is fixed on the main body of the opener.
[0014] Such as figure 2 As shown, it is a schematic diagram of the non-working sta...

The invention discloses an anti-blocking device for a seed-metering fertilizer pipe and a slippage type groove opener employing the device. The anti-blocking device comprises a movable lug used for blocking a pipe orifice of the seed-metering fertilizer pipe, wherein a fixing rack is arranged outside the seed-metering fertilizer pipe; the bottom end of the fixing rack is provided with a fixing rack lug; a movable lug lifting lug is arranged on the movable lug; the fixing rack lug is connected with the movable lug lifting lug through a fixed pin shaft; a torsion spring is sleeved outside the fixed pin shaft; and one end of the torsion spring acts on the fixing rack, and the other end of the torsion spring acts on the movable lug. According to the device, the blockage phenomenon can be avoided, and due to the movable lug with the torsion spring device, the earthing property can be improved, the working efficiency is improved, the operation is convenient, and the working quality is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an anti-blocking device for seed and fertilizer discharge pipes and a sliding opener using the device. Background technique [0002] Sowing and fertilizing is an indispensable link in agricultural activities, and mechanized operations have significant advantages such as high efficiency and good quality, and mechanized sowing and fertilizing is becoming more and more common. But the sowing and fertilizing of crops such as existing wheat, corn, adopt the sliding type ditch opener device more, this class device mainly contains several forms such as hoe shovel formula, boot formula, sliding knife formula. Sliding openers often have the phenomenon that the soil blocks the seed or fertilizer outlet when the operating machinery falls to the ground, especially when the soil moisture content is high and the hydraulic system of the tractor is not good. Such prob...
