Structure and connection relation described in example 1 is identical.
In view of above-mentioned technical proposal, use process of the invention and operation principle are as follows：Horizontally tracting at the uniform velocity under, pass through
The plough shovel of chain drive can allow for travelling forward and be cultivated, by itself weight and with focusing on the depth initially adjusted
Under cultivate forward, provide it is a kind of need not the automation farming machinery device that manually follow or control.The wherein described chain pine
Tightness with level height is determined by the distance between wheel body of drive chain movement of both sides, height and velocity of rotation.
In the present invention, main drive wheel 1 is 2, and interval suitable distance is set up in parallel, and corresponding with main drive wheel 1 set
The auxiliary wheel 9 put is connected by drive chain 2 so that adjacent drive chain 2 can there are mounting blocks before installation 15, in
The space of mounting blocks 22 and fertilizer tube 24.Two main drive wheels 1 rotate synchronously, and realize that drive is auxiliary by drive chain 2
Help the rotation of wheel 9.For the main drive wheel 1 using synchronous motor, synchronous motor passes through synchronous belt（It is not shown in Fig. 1）It will be dynamic
Power is transferred to main drive wheel 1, and preceding mounting blocks 15, middle mounting blocks 22 and fertilizer tube 24 are fixed and by two drive chains 2 by it
The power to travel forward is provided.Operating personnel only need to open synchronous motor, adjust plough shovel into the depth of soil, you can real
The now advance at the uniform velocity under state.
For middle mounting blocks 22 for installing plough shovel sleeve 21, plough shovel sleeve 21 is installed on middle mounting blocks by fixing bolt component
On 22, plough shovel adjusting rod 19 is equipped in plough shovel sleeve 21, plough shovel adjusting rod 19 is equipped with adjustment hole, real by different adjustment holes
The extension elongation of existing regulating plough shovel adjusting rod 19.
Distributor 18, circular tube structure of the distributor 18 for flat port, the flat port are equipped in the end of plough shovel adjusting rod 19
Width be more than fertiliser granulates diameter, it should be noted that by tilt hopper 3 convey fertiliser granulates without caking phenomenon.
If fertilizer has caking, need to be equipped with agitating device in the top for tilting hopper 3, the caking in fertilizer to be broken up.
After plough shovel sleeve 21 is installed on by spiral shell fixing bolt component on middle mounting blocks 22, due to can during advance
It can be acted on by larger resistance, so that plough shovel sleeve 21 loosens.To solve the above-mentioned problems, increase in the present invention
Angular adjustment bar 16 is added, angular adjustment bar 16 is fixed on preceding mounting blocks 15.
Distributor 18 is connect by hose 20 with fertilizer tube 24, fertilizer tube 24 to receive from tilt hopper 3 fertilizer,
And the fertilizer is subjected to a degree of uniformity stirring, those skilled in the art can set up low power stir in fertilizer tube 24
Mix mixing arrangement, different types of fertilizer is carried out a degree of stirring, due to the fertilizer total amount in fertilizer tube 24 compared with
It is small, therefore low power mixing stirring device such as micro-machine wears auger structure or the stirring flabellum of routine can be realized.
Mixed fertilizer or the fertilizer of single kind can be entered after fertilizer tube 24 in telescoping tube 23, telescoping tube
Be equipped with multiple foldable structures in 23, such structure can delay in the fertilizer short time a large amount of fertilizer be concentrated through exporting into
Enter the function of hose 20, so as to fulfill fertilizer in the process of running sow uniformity, so as to ensure dose fluctuation model
It is identical in enclosing.
The major function and feature of the present invention is：Pass through the plank structure of two pieces of outer walls being set up in parallel 30 in the present invention
Into hopper 3 is tilted, since such inclination 3 bottom of hopper is without baffle, bottom is used as using closure belt 4 in the present invention
Portion's baffle.
It blocks belt 4 and includes plugging plate 4-1, trapezoidal groove 4-2, partition board 4-3, hopper track 4-4, outer wall 30 is located at respectively
In hopper track 4-4, fertilizer is located in trapezoidal groove 4-2, and partition board 4-3 is used to prevent a certain amount of fertilizer of trapezoidal groove 4-2 from existing
It blocks and is moved in belt 4.Block upper winding roller 5, lower winding roller 6 and mobile winding roller that belt 4 is distributed by triangle position
31 move and to realize positioned at the adjusting for tilting 3 lower length of hopper.Upper winding roller 5 and lower winding roller 6 are located at it for conveying
On closure belt 4, block belt 4 by under the action of outer wall 30, hopper track 4-4 along tilt hopper 3 move downward, and
The steering for blocking belt 4 is realized under the action of mobile winding roller 31.
Since mobile winding roller 31 is located at the top of fertilizer tube 24, and fertilizer tube 24 travels forward with drive chain 2, institute
Realize that the closure belt 4 for being located at and tilting below hopper 3 is grown under the action of upper winding roller 5, lower winding roller 6 to move winding roller 31
Degree is adjusted.Above device drives rotation by winding driving device 7, and winding driving device 7 is realized using motor.This field
Technical staff realizes that winding driving device 7 drives the rotation of upper winding roller 5 and lower winding roller 6 by existing transmission device.
In order to ensure the operation stability of the present invention, limit switches 10, limit are installed before and after the present invention on pedestal 27
Bit switch 10 coordinates with front stop lever 13, rear bar 25, prevents the mechanism from colliding during the motion.Similary miscellaneous function
Also it is located at the photoemitter 14 on front stop lever 13 and the photelectric receiver 11 in 12 fixing device of intermediate supports wheel, uses
To shift to an earlier date position detection of the suitable distance realization to preceding mounting blocks 15.After the reception of photoemitter 14 and photelectric receiver 11,
Signal after reception is transferred to controller to show, wherein what the photoemitter 14 was used with photelectric receiver 11
It is the visible light laser emitter receiver of the model FU-JGDS-10-30V-M12 of complete sale, response time ＜ 3ms, effectively
Distance is 30m, output signal：NPN（Negative signal）Thang-kng is low level（0V）, shading be high level（10V-30V）, built-in tune
System demodulation（It is anti-interference）.It is 10 ~ 30V of direct current to receive signal and the voltage of output.Heretofore described photoemitter
14 and photelectric receiver 11 as the switch element on circuit, can be by the indicator light and power supply on circuit after the two is connected
It is connected by conducting wire, so as to fulfill the light prompting to operating personnel, operating personnel is reminded to plough the movement position of shovel.
Equally, the present invention can realize the rotation of main drive wheel 1, fertilizer charging by way of manually manipulating executing agency
Mechanism can also pass through PLC to tilting the feeding of hopper 3, upper winding roller 5 and lower winding roller 6 to blocking the submitting and backrush of belt 4
Control device or the achievable single-chip microcomputer integrated circuit of those skilled in the art realize the accurate control to the above process.
