Description
The present invention relates to a kind of paddy field rice transplanter, it can make the rice shoot planting apparatus keep constant attitude with respect to the face of land, because body moves both vertically with the variation generation on the face of land, make the rice transplanter hull change the generation vertical displacement, make hull keep a kind of attitude within the specific limits with respect to the rice shoot planting apparatus by lifting rice shoot planting apparatus to the contact pressure of earth; It can also regulate the lifting control sensitivity of rice shoot planting apparatus automatically according to the vibration displacement amount that earth hardness is surveyed, and the hardness detection part extends into earth, and when machine was advanced, the resistance that is run into had caused the vibration of detection part.
The paddy field rice transplanter that a kind of vibration displacement amount of utilizing hull is controlled the lifting of rice shoot planting apparatus has been that the people is known.Such known planter uses control device with to acting on the testing result reaction of the earth contact load on the hull, automatically the planting apparatus lifting, keeps depth of planting substantially constant, and hull is pressed on the earth with spring.In order to carry out depth of planting control reliably, must be to hull being pressed in the power on the earth, the different earth hardness according in the different plot are adjusted to suitable power.
For this reason, can imagine the elevator of earth hardness detection piece and planting apparatus is connected, and react, regulate the reaction relation between hull and the elevator with the testing result of earth hardness detection piece.But this arrangement is except needing the jockey between elevator and the hull, also requires to have the jockey between elevator and the earth hardness detection piece, but also needs a special device to make elevator.This has huge and complicated shortcoming with regard to having caused total.
Purpose of the present invention is to propose a kind of paddy field rice transplanter, and a kind of creative jockey of novelty is arranged between elevator and hull and earth hardness detection piece, can eliminate shortcoming recited above.
Why this purpose can obtain, and is the connection that is not provided with between elevator and the earth hardness detection piece, and the testing result of earth hardness detection piece, directly supplies with hull, so as to regulating the sensitivity of hull.The planting mechanism that the present invention proposes has following characteristics:
Hull is connected with planting apparatus, and planting apparatus is provided with a connector around first strong point vertical oscillation of hull, one second strong point vertical oscillation on hull, and second strong point is provided in a side of the place ahead of first strong point,
Connector has a jockey on fore-end, reach on the elevator, on a rearward end relative with leading section, has a pressing device to cross second strong point, and hull is pushed to landing ground.
An earth hardness detection piece is set, reaches earth the inside, can swing jointly, resist the pressing device applied pressure, and the change in resistance of the generation when contacting with earth because planting mechanism advances is swung with connector.
Elevator can make planting apparatus move along with the vertical oscillation of hull, the vibration of hull is to cause and by the jockey transmission owing to change in resistance, thereby keep the gauged distance between planting apparatus normal place and the connector front end constant, at this moment, the sensitivity of hull is regulated automatically with the variation of the pressing device downward pressure that vibration caused of earth hardness detection part.
Said structure produces following two kinds of functions:
(1) earth hardness detection piece is connected with pressing device, the hull that can handle the planting apparatus lifting to pressing down, when the plot is hard, because the swing of the earth hardness detection piece that causes of earth interface pressure, increase the pressure of pressing device, thereby reduce the sensitivity of hull.On the contrary, when the plot was soft, because the earth interface pressure lowers, the swing of earth hardness detection piece in earth made the pressure of pressing device reduce the sensitivity of just having increased hull.Planting apparatus is just by lifting reliably like this.In addition, earth hardness detection piece is connected with connector, does consistent swing, be added in the downforce on the pressing device, also be used as the downforce that acts on the earth hardness detection piece for the downforce of pressing device is delivered to.
(2) in addition, link member has a front end and its pivot of rear end between two ends, and front end is connected with jockey on reaching the planting apparatus elevator, and the rear end is connected with pressing device.Therefore, as an example, when earth hardness detection piece was upwards swung owing to running resistance, connector is upwards swing jointly thereupon.So just, increased the pressure of pressing device.In this case, because planting apparatus is raised or descends, keep the front end of link member and the normal bit of planting apparatus to be equipped with a constant distance, earth hardness detection piece causes the swing of link member, the pivoting point that makes link member is in vertical direction with respect to the hull activity, and direction is identical with the activity direction of link member rear end.Therefore, when earth hardness detection piece was put upward owing to running resistance, the above-mentioned pivoting point that is positioned at the hull leading section just moves up, so the attitude of hull is: front end rose, and the sensitivity of hull reduces.
Because function (1) arranged, what structure can be than in the prior art is simple in structure, because only need change the pressure that is added on the hull.Owing to be added in the pressure on the hull, can also utilize the pressure that acts on the earth hardness detection piece, so only just can play whole effects with a pressing device.These characteristics help further simplified structure.Therefore, the present invention has proposed a kind of very simple structure aspect total, and building block is arranged the position easily, is that good characteristics are arranged aspect maintenance.
Because function (2) is arranged, the present invention by pressing device applied pressure on hull, changes the sensitivity of hull than only, and bigger advantage is arranged, and reason is under the assistance that the hull attitude changes, and sensitivity control has higher reliability.
According to a desirable embodiment of the present invention, in the above-mentioned jockey of planting apparatus, a release cable is arranged, wherein there is interior cable to be fixed on the leading section of link member, have an outer cable to be fixed on the support member that stretches out from planting apparatus, interior cable installation end and outer cable installation end are placed on and center on the arcuate member of first strong point, or around it, distance between interior cable installation end and the outer cable installation end, the gauged distance of formation lifting controller.
According to above-mentioned structure, because hull is swung in vertical direction, the cable installation end is when sliding with respect to outer cable installation end in making, be placed on the part of the interior cable of outer cable the inside, and from outer cable installation end reach and the end of the interior cable that link member is fixing between relative attitude change, on the circular arc spare of first strong point, or in its annex generation, this strong point forms the swinging axle of hull.These characteristics have avoid in the effect reversed on the cable installation end outside of cable.
Therefore, interior cable can be made the smooth sliding with respect to outer cable, and this can steadily swing hull in vertical direction, and steadily and reliably oscilaltion of planting apparatus.In addition, because cable installation end and be fixed on a part of the interior cable that stretches between the interior cable ends on the link member outside, form around a string of a sizable circular arc of radius of first strong point, and interior cable installation end and outside stretch between the cable installation end, therefore when interior cable slides, only by a very narrow scope, that is to say that its track only accounts for a very little area, therefore the installation to miscellaneous part does not almost have obstacle.
Another desirable embodiment according to the present invention has an earth contact portion that reaches earth the inside in the earth hardness detection piece, be placed on planting apparatus planting mechanism near.
According to this structure and since first strong point of hull be placed on planting mechanism near, reach near the earth contact portion the planting mechanism, be in first strong point near, though hull has swing up and down, keep earth to contact degree of depth substantially constant.Therefore, earth hardness detection piece can be carried out its measuring ability reliably, and this just can guarantee the reliable running of hull, and correctly grasps the hardness in plot, with the control planting apparatus.
