Detailed Description
As shown in fig. 1 to 11, the present invention mainly includes a frame 1, a detecting unit and an adjusting unit, and the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the frame 1 is a main body of the present invention, and four legs 11 are provided at the bottom of the frame, and rollers 12 are provided at the bottom of the legs to facilitate the overall movement.
As shown in fig. 1 and 7, two detection units are provided and are respectively provided on two adjacent side walls of the rack, such as a front side wall and a right side wall. As shown in figure 2, the detection unit comprises a ']' -shaped conduit 2, water 22 arranged in the conduit, floating balls 23 arranged in two ends of the conduit and plugs 21 arranged at two ends of the conduit, wherein the conduit is a transparent plastic pipe, the opening of the conduit is upward, and the conduit is fixedly connected with the frame. When the gantry is in the horizontal plane, the duct is also in the horizontal plane. As shown in FIG. 3, when the frame is in the horizontal plane, the water level at the two ends of the conduit is flush, and at this time, the two floating balls are located in the same height plane. The plug is directly plugged into the pipe orifice of the conduit, and the plug is provided with an air hole so as to facilitate the communication of the conduit and the outside air. As shown in fig. 11, the floating ball 23 is a plastic ball, and a black light shielding band 24 is disposed in the middle of the floating ball, and the light shielding band can block the linear transmission of infrared rays. The floating ball is transparent except the place where the shading band is arranged. For ease of viewing, the water is red or blue water.
An infrared emitter 3 fixed on the side wall of the frame is arranged between the two ends of the guide pipe, infrared receivers 4 are respectively fixed at the two ends of the side wall of the frame where the infrared emitter is installed, and the guide pipe is arranged between the two infrared receivers. The connection line of the two infrared receivers passes through the infrared transmitter.
As shown in fig. 4, when the rack is in the horizontal plane, the infrared emitter emits infrared rays 5 to both sides, and at this time, the infrared rays and the symmetrical plane of the shading band are in the same horizontal plane, and the shading band blocks the infrared rays, so that the infrared receiver does not receive the infrared rays, indicating that the rack is in the horizontal state. When the frame is slightly inclined, the shading band has a certain width and can still block infrared rays, at the moment, the two infrared receivers still cannot receive the infrared rays, and at the moment, the frame can be considered to be in an approximately horizontal state.
As shown in fig. 6, when the rack moves to the inclined plane 6, the inclination angle of the rack is large, as shown in fig. 5, the floating balls at the two ends of the guide pipe are staggered up and down, the infrared ray 5 emitted by the infrared emitter disappears in the process of linear propagation, the influence of the shading band on the infrared ray disappears, the infrared ray penetrates through the floating balls and then continues to be propagated until being received by the infrared receiver, the rack is in an inclined state and the inclination angle is large, the sowing precision is influenced, and the sowing distance is small and large. The infrared receiver is in signal connection with the PLC on the rack.
As shown in fig. 8, the supporting leg comprises an upper rod 111 and a lower rod 112, a first electric telescopic rod 7 is arranged between the upper rod and the lower rod to adjust the length of the supporting leg, and the PLC controller is in signal connection with the first electric telescopic rod. If the front end of the rack is high or low, after the detection unit on the right side of the rack detects the inclined state of the rack, a signal is sent to the first electric telescopic rod on the supporting leg on the front side of the rack, so that the front side of the rack descends or raises. When the left end of the rack is high or low, after the detection unit on the front side of the rack detects the inclined state of the rack, the detection unit sends a signal to the first electric telescopic rod on the front right supporting leg of the rack, so that the left side of the rack descends or raises. The first electric telescopic rod constitutes an adjusting unit.
As shown in fig. 9 and 10, the adjusting unit may have other configurations, and in this case, the adjusting unit includes a screw 71 rotatably connected to the upper rod and having a lower portion extending into the lower rod, a driven bevel gear 72 fixed to the screw, an ear plate 74 fixed to the bottom of the upper rod, a drive bevel gear 73 and a drive sprocket 75 rotatably mounted on the ear plate, an adjusting sprocket 76 movably disposed at the bottom of the frame, a chain 77 disposed between the drive sprocket and the adjusting sprocket, and a driving mechanism for driving the adjusting sprocket to move up and down, and the screw is disposed in the upper rod of three legs, such as two legs at the front end of the frame and the other leg at the right end of the frame. And a motor is arranged on the middle leg of the three legs to drive the transmission chain wheel to rotate. The driving mechanism comprises a mounting plate 81 fixed at the bottom of the rack and a second electric telescopic rod 8 fixed on the mounting plate, wherein the second electric telescopic rod stretches and retracts to drive the adjusting chain wheels to lift, and therefore the tightness and tightness of a chain between the two driving chain wheels are achieved. Screw-thread fit between lead screw and the lower beam, universal connection between upper boom and the frame to the needs when satisfying the landing leg and going up and down. And the second electric telescopic rod and the motor are in signal connection with the PLC.
If the chain at the front end of the rack is loose and the chain at the right end of the rack is tight, the transmission chain wheel on the left side of the front end of the rack does not rotate, so that the supporting leg on the left side of the front end of the rack is static, the transmission chain wheel on the right side of the front end of the rack rotates, and the supporting leg on the right side of the front end of the rack goes up and down. The transmission chain wheel at the rear side of the right end of the rack rotates, and then the supporting legs at the rear side of the right end of the rack lift, so that the two supporting legs at the right end of the rack lift. Similarly, when the chain at the front end of the rack is tight and the chain at the right end of the rack is loose, the two supporting legs at the front end of the rack lift. When the chain at the front end of the rack is tight and the chain at the right end of the rack is tight, the front end and the right end of the rack simultaneously ascend or descend.
The invention can realize the detection of the inclined state of the rack, when the inclined state of the rack exceeds a set value, the detection unit sends a signal to the PLC controller, and at the moment, the PLC controller controls the adjusting unit to act to drive the corresponding side rack to rise or fall, so that the rack is kept in a horizontal state on uneven ground, and the seeding precision is guaranteed.
