Description
The utility model relates to a kind of agricultural seeder machinery.
Existing Drilling-hole seeder mainly is to be chewed by the cylindrical housings, the punching that is evenly distributed on the housing outer rim of sealing, chews pressing plate that valve links to each other and chews the kind spoon formation of corresponding setting with punching with punching.The deficiency of this sower is: the seed that is full of in the housing easily will be planted a spoonful crimp, be directed at the amount of seed metering inequality; The unlatching of valve is chewed when extract on ground pressing plate by punching and is crushed on ground and realizes, this not only damages mulch film easily, and influence speed of drilling, if the sower rotating speed is fast slightly, then the shortening of valve opening time is chewed in punching, seed can not all be discharged or easily seed is discharged to outside the hole, and therefore the accuracy and the reliability of this sower are relatively poor.
The purpose of this utility model is to provide a kind of reasonable in design, sows Drilling-hole seeder accurately and reliably.
The purpose of this utility model is achieved in that Drilling-hole seeder comprises seeding box, seeding wheel, discharging tube, valve, its special character is to be connected on the seeding wheel along the circumferential equally distributed discharging tube of seeding wheel at regular intervals, the openend of each discharging tube promptly punches to chew through the sowing roller wheel outer surface and stretches out outside the wheel, punching is provided with valve in chewing, one end of its curtain shaft links to each other with crank one end of corresponding setting, the other end of crank is connected with back-moving spring, be fixed on the wheel shaft with crank place cam one end at grade, the other end is provided with down, it will promote to turn to the crank of this position, valve is opened, opposite side at the discharging tube relative with cam is provided with the seeding box that is enclosed within on the wheel hub, be provided with the seed plate that is connected on the wheel hub in the seeding box, tank wall top by the discharging tube side is provided with sowing port, the seeding spoon that this mouthful energy will turn on the seed plate outer rim of the seed inlet of discharging tube at this mouthful place and corresponding setting with it is connected, and the seed in the seeding spoon is entered in the discharging tube.
The grain tube of certain insertion depth vertically is set in seeding box, and the upper port of grain tube is the seed inlet of seeding box.Utilize the control of the insertion depth realization of grain tube to kind position, seeding chamber height, so that the seeding spoon on the seed plate surpasses when planting the position height, the unnecessary seed in seeding spoon outside comes off in rotation process naturally.
The utility model compared with prior art has following characteristics: adopt cam to open valve, can not damage mulch film, by cam width and position be set opening time and the perdurabgility that determines valve, sow accurately and reliably, and can improve operating speed; The kind position height of seed plate and restriction seeding chamber vertically is set, the outside unnecessary seed of the seeding spoon that exceeds kind of position height is come off naturally, therefore seeds scraper need be set, avoid damaging seed and seed is squeezed in the seeding spoon; This machine is simple in structure, part exchanging convenient, can change seed plate, a tractor serves several purposes according to the requirement of amount of seed metering and seed variety.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Be described in further detail below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, the wheel hub (2) of seeding wheel (1) is enclosed within on the wheel shaft (3), is fixedly connected with 6 discharging tubes (5) that distribute along circumferentially on the spoke of seeding wheel (4), and discharging tube can be provided with as required.Differ 60 ° of angles between two discharging tubes, the openend of discharging tube stretches out outside the wheel through the seeding wheel outer surface, and the discharging tube of extension is the punching of sower and chews, and discharging tube and punching are chewed and can be one, also can be two parts of mutual grafting, the latter is convenient to make and is changed punching and chew.Be provided with tabular valve (6) in punching is chewed, the one end is fixedly connected on the curtain shaft (7), and the two ends of axle are arranged on the tube wall, and the best evagination of tube wall herein like this, can not be obstructed because of the setting of curtain shaft through herein seed.One end of curtain shaft passes tube wall and spoke is connected with an end of the crank (8) that is positioned at discharging tube one side and corresponding setting, and the crank other end is connected with back-moving spring (9), and the other end of back-moving spring is fixed on the spoke.When the position of crank and back-moving spring was provided with and should satisfies no external force and act on the crank, valve was in closed condition under the effect of spring force, and when external force acted on the crank, valve was in opening.Be fixedly connected on the wheel shaft with crank place cam (15) one ends at grade, the other end is that protruding end is provided with down, and cam will promote to turn to the crank of this position, makes it drive valve and opens.Opposite side at discharging tube is provided with the seeding box (10) that is enclosed within on the wheel hub, vertically be provided with in the seeding box and lean against on the wall box and the seed plate (11) that is connected with the wheel hub key, the corresponding position of seed plate outer rim and discharging tube is provided with seeding spoon (12), seeding tank wall top by the discharging tube side is provided with sowing port (13), the seed inlet that this mouthful energy will turn to the discharging tube at this mouthful place synchronously is connected with the seeding spoon, and the seed in the spoon is fallen in the discharging tube.Be vertically set on the grain tube (14) in the seeding box, its upper port is the seed inlet, and lower port is positioned at lower box.
Seeding wheel is during along ground surface, is installed in discharging tube on the seeding wheel, seed plate with its synchronous rotation.Entering seed in the discharging tube falls in rotation process in punching chews, when insertion ground is chewed in punching, the cam throw crank is opened valve, when valve is opened the hole is planted in the ground dial-out, seed falls in the hole, seeding wheel is rotated further, and crank breaks away from cam, and valve is closed under the effect of back-moving spring.Also will finish with its seed plate that rotates synchronously and to fill kind and seed is sent to the course of work in the discharging tube.
Claims (2)
