In the moving process of the driving wheel 9, the quantitative water applying mechanism 2 can be driven to carry out pre-water applying operation (i.e. applying fertilizer first, then applying water and finally sowing) on the seed sowing position after the fertilizer is put into the sowing mechanism, when the quantitative water applying mechanism is specifically implemented, the driving wheel 9 can directly drive the rotating wheel pointing device 8 to drive the water applying column 202, so that the fixed-point water applying can be carried out periodically in the seed furrow, and in the entering process of the water applying column 202, the rated water feeder 4 can freely feed the quantitative water into the water applying column 202, so that the water applying column 202 can spray quantitative water at the seed sowing position in the seed furrow every time, so as to avoid the waste of water resources, meanwhile, when the seed furrow is inserted, the seed furrow contact table 6 is directly inserted into the seed furrow, and the seed furrow contact table 6 can break the caked soil at the seed sowing position, so that the sprayed water is fully soaked by the soil.

As shown in fig. 1 and 2, a plurality of breaking bars 601 which are arranged in an inverted V-shaped longitudinal section and used for breaking the soil blocks are arranged at one end of the seed trench contact platform 6 far away from the water applying column 202, a converging cover 602 is arranged at one end of the seed ditch contact platform 6 close to the water applying column 202, a plurality of inclined water applying rings 603 for uniformly spraying water in a small range are arranged on the side wall of the seed ditch contact platform 6, the water applying columns 202 are totally three, and the three water applying columns 202 are respectively of a T-shaped structure, an L-shaped structure and an I-shaped structure, and the structure of a plurality of water applying columns 202 is arranged for adjusting the number of the seed furrow contact tables 6 according to the positions of the seed sowing positions, the operation of driving in the soil at the seed sowing position through the seed furrow contact table 6 is achieved, the situation that part of the seed sowing positions are not sprinkled with water is avoided, and the longitudinal section of the seed furrow contact table 6 is of an isosceles trapezoid structure.

This kind of ditch contact station 6 can realize that soil is smashed and bayonet watering operation, and it can be at the even watering of seed scattering department, still can insert the kind ditch simultaneously and make the soil of seed scattering department can store sufficient water.

As shown in fig. 1, 5 and 6, the rotating wheel pointing device 8 includes a connection column 801 and a wheel rotating disc 802 connected to a chain 901, the wheel rotating disc 802 is connected to the fixed block 201 through the connection column 801, a driving column 803 is installed on the surface of the wheel rotating disc 802, a side wall of the driving column 803 is connected to a traction column 804, a containing square hole 805 for containing the traction column 804 to move is formed in the side wall of the fixed block 201, a pulling column 806 is installed at one end of the traction column 804 far away from the driving column 803, and a pulling and sliding hole 807 for clamping the water applying column 202 is formed in the side wall of the pulling column 806.

In the embodiment of the present invention, as shown in fig. 1, once the frame 1 moves toward the left side, both the chain 901 and the wheel rotation plate 802 rotate counterclockwise.

Further, in order to break the agglomerated soil at the seed sowing position and achieve the purpose of higher watering uniformity, in the specific implementation, it is necessary to work with the rotating wheel pointing device 8, when the driving wheel 9 moves, the wheel rotating disc 802 is driven, then the movable wheel rotating disc 802 rotates freely, then the wheel rotating disc 802 can drive the driving column 803 and the traction column 804 to move together, then the movable traction column 804 moves in the accommodating square hole 806 (taking fig. 5 as an example, the traction column 804 sequentially performs operations of left, bottom and right, because the driving column 803 is installed at the surface edge position of the wheel rotating disc 802, it rotates together with the wheel rotating disc 802, when the wheel rotating disc 802 drives the driving column 803 to move counterclockwise, the driving column 803 can circle counterclockwise, that is, the traction column 804 sequentially performs operations of left, bottom and right), when the pulling column 806 is driven by the traction column 804 to move up and down, the watering column 202 also moves up and down, when the pulling column 804 moves left and right in the receiving square hole 806, the water application column 202 can move left and right in the pulling and sliding hole 807, and the water application column 202 is limited by the fixing block 201, so that the left and right movement of the pulling and positioning column 806 can not be easily blocked.

When the pulling column 806 moves, the water application column 202 is also driven, so that the water application column 202 drives the seed furrow contact table 6 to be periodically inserted towards a seed sowing place (the seed sowing place is a position for sowing seeds by the corn sowing executing mechanism 103), at the moment, the inserted seed furrow contact table 6 can be directly embedded into the seed sowing place through the breaking strips 601, in the process, the breaking strips 601 embedded into soil can break caked soil at the seed sowing place to avoid absorbing a large amount of water, so that the condition of uneven soil wetting is caused, meanwhile, the gathering cover 602 and the oblique water application ring 603 can simultaneously push the soil open, the gathering cover 602 can firstly separate the broken soil to form a fully wetted point of the soil, then the oblique water application ring 603 can form a channel at the soil sowing place, then water introduced into the water application column 202 from the connecting pipe 5 can directly enter the seed furrow contact table 6 and is gradually sprayed out from the oblique water application ring 603, then spun water can directly get into soil and form in the channel for soil can fully water storage all around, so that the soil of scattering department all around is moist enough, but the moist condition in soil top layer can not appear, later when the seed gets into the scattering department, can be covered by fully moist soil.

The gathering cover 602 can also play a role in blocking the gathered and sprayed water, namely, the gathering cover 602 can enclose a sprinkling range at the seed sowing position, and sprinkling, soil breaking, sowing and soil covering can be carried out only in the range, so that further water-saving operation is realized.

As shown in fig. 2, a guiding groove 6011 is disposed at one end of the breaking bar 601, which is far from the seed trench contact platform 6, a push-away bar 6012 for pushing away the stone and soil blocks is disposed in the guiding groove 6011, one end of the push-away bar 6012 is directly connected to the seed trench contact platform 6, an auxiliary push ball 6013 is disposed at the other end of the push-away bar 6012, a push-rake bar 6014 is disposed on a side wall of the push-away bar 6012, which is close to the auxiliary push ball 6013, and a reset spring 6015 connected to the push-away bar 6012 and used for assisting the reset of the push-away bar 6012 is disposed on a side wall of the seed trench contact platform 6.

Furthermore, in order to prevent soil from having hard soil blocks which are difficult to crush and affecting the wettability of the soil surface in the crushing process, the soil needs to be pushed away from a seed sowing place, when the seed sowing place is implemented, once the crushing strips 601 and the converging cover 602 are inserted into the soil, the auxiliary pushing ball 6013 directly contacts the soil, then the auxiliary pushing ball 6013 slides along the soil along with the descending of the crushing strips 601 and the converging cover 602, the pushing strips 6012 deflect and move along with the pushing strips 6012 in the direction away from the seed ditch contact platform 6, and then the movable pushing strips 6012 drive the pushing and raking strips 6014 to push the hard soil blocks in the soil away from the seed sowing place, so that the water application efficiency is not affected, and in the deflection process of the pushing strips 6012, the reset springs 6015 are squeezed, so that when the crushing strips 601 and the converging cover 602 are separated from the soil, the pushing strips 6012 can be reset easily.

The inclined water applying ring 603 comprises a water ring strip 6031 arranged on the side wall of the seed ditch contact platform 6, a plurality of range columns 6032 with different lengths are arranged on the side wall of the water ring strip 6031, and the inclined water applying ring 603 is arranged in such a way as to ensure that the wettability of soil everywhere where seeds are sowed is uniform.

the corn seeding executing mechanism 103 pushes the plugging block 701 to slide along the fixed sleeve 203, so that the flowing medium in the pressing return cavity 7034 is extruded to enter the swelling return cavity 7033, the swelling return cavity 7033 is expanded, meanwhile, the flow hole 702 is coincided with the center of the water applying column 202, the seed ditch contact platform 6 is enabled to uniformly spray water, the swelling return cavity 7033 is reset, the flowing medium in the swelling return cavity 7033 is pushed to flow into the pressing return cavity 7034, and the plugging block 701 is pushed to reset.

Furthermore, in order to prevent the water application column 202 from always performing the water application operation, the water application column 202 needs to be controlled so that the water cannot be always discharged, in the daily situation, the slow reset table 703 blocks the water application column 202, once the corn seeding actuator 103 rolls, the discharge port on the water application column will shift the inclined push table 704 on the blocking block 701 so as to move towards one side of the rubber bag 7031, then the pressed rubber bag 7031 will directly press the flowing medium in the pressing return cavity 7034 into the swelling reset cavity 7033 and expand the swelling reset cavity 7033, at the same time the flow hole 702 coincides with the center of the water application column 202, so that the seed furrow contact table 6 uniformly sprays water, then once the components (such as a duck bill and the like) on the corn seeding actuator 103 do not press the rubber bag 7031 (the rubber bag 7031 is selected to reduce the return force of the blocking block 701, so that the blocking block 701 cannot damage the corn seeding actuator 103 due to instantaneous resetting), the bulged reset cavity 7033 will reset and slowly press the flowable medium (e.g., water) therein back through the restricted orifice 7035 into the forced reset cavity 7034, after which the block 701 will be pushed to gradually reset and block the water from exiting.
