Description

Positioning clutch of seeder

Technical Field

The utility model relates to agricultural machinery, in particular to a clutch for a seeder.

Background

With the rapid development of agriculture, the field of agricultural planting is also increasingly focused, and the position is also higher and higher. Among them, high yield and high efficiency of agricultural planting become important directions of attack. The corn-shaped sowing planting mode has the characteristics of ventilation, light transmission, high yield and high efficiency, and is popular with vast growers. In the past, the Chinese character 'pin' type planter is realized that multirow is sowed simultaneously under the mode of mechanical linkage, and the seed metering process of all seed cases goes on simultaneously, can not stop the seed metering process alone. In the past field operation, when one row or a few rows cannot be sowed at full load, the seeds in the non-working seed sowing device need to be completely emptied. The operation can avoid the waste of seeds, but the whole progress of spring tillage seeding operation can be influenced when the operation is misworked.

Disclosure of Invention

The technical problems to be solved by the utility model are as follows: aiming at the problems, the positioning clutch structure of the seeder is provided to realize the function that the seed sowing device can be closed at any time.

The technical scheme of the utility model is as follows: the utility model provides a seeder positioning clutch, includes input shaft and power take off unit, power take off unit includes cover on the input shaft and along with its pivoted follower and driving piece, be equipped with the locked groove on the follower and with the actuating element be connected and output power's power take off portion, the follower passes through the bearing rotationally with the input shaft to be connected, articulated on the driving piece have be used for with locked groove complex locking piece and be equipped with the locating part beside the locking piece, be equipped with locking part and operating portion on the locking piece, the locating part is used for prescribing a limit to the locking piece on two stations of locking position or unblock position, the driving piece sets up by the follower and with input shaft fixed connection, pull operating portion can make the locking part of locking piece get into in the locked groove on the follower, make follower and driving piece linkage.

The utility model has the technical effects that: the clutch has the advantages of simple structure, reasonable design and easy operation, is arranged on a power shaft, corresponds to the seed metering devices of the seed boxes one by one, drives the seed metering devices to operate, and can stop any seed metering device through the separation of the clutch when needed.

Description of the embodiments

As shown in fig. 1 and 2, a positioning clutch of a planter comprises an input shaft 1 and a power output unit, wherein the power output unit comprises a driven member 2 and a driving member 3, the driven member 2 is sleeved on the input shaft 1 and rotates along with the input shaft, a locking groove 4 and a power output part 5 which is connected with an executing element and outputs power are arranged on the driven member 2, the power output part is used for being connected with a belt or a chain and the like, the power input by the input shaft is transmitted to the executing element end, the driven member 2 is rotatably connected with the input shaft 1 through a bearing 6, a locking block 7 which is matched with the locking groove 4 is hinged on the driving member 3, a limiting member 8 is arranged beside the locking block 7, a locking part 9 and an operating part 10 are arranged on the locking block 7, the limiting member 8 is used for limiting the locking block 7 at two positions of a locking position or an unlocking position, the driving member 3 is arranged beside the driven member 2 and is fixedly connected with the input shaft 1, and the locking part 9 of the locking block 7 can be moved into the locking groove 4 on the driven member 2 by pulling the operating part 10 so that the locking part 9 of the locking block 7 enters the locking position and is linked with the driving member 3.

The limiting piece 8 is an elastic baffle, two adjacent surfaces which are at an angle of about 90 degrees and are respectively corresponding to the locking position and the unlocking position and are used for being attached to the elastic baffle are arranged on the locking piece 7, and the elastic baffle is fixed beside the locking piece 7 and is attached to one surface.

The power output part 5 is a sprocket.

The driving part 3 is fixedly connected with the input shaft 1 through jackscrews.

The input shaft 1 is a hexagonal shaft.

The input shaft obtains a power source from the equipment, and the power is transmitted to the seed metering mechanism through the positioning clutch of the seeder, at the moment, the locking block is positioned in the locking groove, and the driving piece drives the driven piece to rotate. When the action of a specific seed metering device is required to be stopped, the operation part of the clutch locking piece is manually pulled, so that the elastic baffle piece is attached to the other matching surface of the locking piece, and the locking part leaves the locking groove, thereby releasing the power transmission to the seed metering device.
