Self-propelled carrot seed rope planter
[0001] The invention relates to agricultural machinery, in particular to a
self-propelled carrot seed rope planter.
[0002] The traditional carrot planting method is broadcast sowing and sowing in
drill. After the seedling emerges, artificial thinning is required, which not only wastes
man-hours, but also wastes seeds and increases planting costs. Precise seeding of
carrots can reduce the thinning link and save seed costs at the same time. At present,
one of the technical equipment to realize the precision seeding of carrots is the air
suction precision planter, and the other is the precision seeding based on the seed rope
mode. The air suction precision planter has a complicated structure and a high price,
and the seeds need to be pelletized. The precision seeding based on the seed rope
mode is divided into two steps. First, the seed rope knitting machine is used to
accurately wrap the seeds into the degradable paper seed belt according to the
corresponding plant spacing and weave the seed rope and wind it into a roller. Second,
the seed rope of the roller is laid under the field soil to complete the sowing. At
present, the seed rope sowing equipment used in the second link mainly relies on the
pressure of the walking press wheel to pull the seed rope from the seed rope roller.
Due to the weak tensile strength of the seed rope, this will cause the seed rope to be
often broken.

[0029] The elastic roller pressing seed rope synchronous laying device 2 includes
two elastic roller pressing seed rope synchronous laying device units; as shown in
Figure 2, the elastic roller pressing seed rope synchronous laying device unit includes
a seed rope roller 201, a synchronous pressure roller 202, a pressing mechanism and a
synchronous ground wheel 214. The synchronous pressure roller 202 is located
behind the seed rope roller 201, the seed rope roller 201 is connected to the frame 8
through the seed rope roller support frame 218. The seed rope roller support frame
218 is welded and fixed to the upper end of the front part of the frame 8. The seed

[0030] The pressing mechanism includes a spiral spring 203, a pressure roller
guide sleeve 204, a long screw 205, a pressure regulating nut 206 , a pressure roller
sliding U-shaped frame 207 and a pressure roller support frame 208; the synchronous
pressure roller 202 is rotatable connected with the two ends of the sliding U-shaped
frame 207 of the pressure roller through the synchronous pressure roller shaft 220 in
the center; thus, the connection between the synchronous pressure roller 202 and the
pressing mechanism is realized. The pressure roller guide sleeve 204 is H-shaped,
which includes two parallel horizontal sleeves and a connecting rod connecting the
two horizontal sleeves; the two horizontal sleeves are respectively sleeved on the two side walls of the sliding U-shaped frame 207 of the pressure roller, and the sliding
U-shaped frame 207 of pressure roller slides back and forth along the pressure roller
guide sleeve 204, thereby driving the synchronous pressure roller 202 to move back
and forth. The pressure roller guide sleeve 204 is fixedly connected to the frame 8
through two pressure roller support frames 208 below it; the top ends of the pressure
roller support frame 208 are respectively fixedly connected with the horizontal sleeve,
the bottom end of the pressure roller support frame 208 is fixedly connected with the
frame 8.
[0031] The connecting rod of the pressure roller guide sleeve 204 is connected
with the bottom of the pressure roller sliding U-shaped frame 207 by a long screw 205,
the end of the long screw 205 facing the synchronous roller is fixed with a protrusion;
a compressed spiral spring 203 is arranged between the protrusion and the connecting
rod; the spiral spring 203 is sleeved on the long screw 205; the other side of the
corresponding long screw 205 is provided with a pressure regulating nut 206 for
adjusting the internal compression force of the spiral spring 203; the pressure
regulating nut 206 located on the outside of the sliding U-shaped frame 207 of the
pressure roller. The spiral spring 203 is always in a compressed state, so the
compression force in the spiral spring 203 springs causes the long screw 205 to
generate a tensile force. At this time, the long screw 205 pulls the pressure roller
sliding the U-shaped frame 207 and the synchronous pressure roller 202 to move
toward the seed rope roller 201. The roller surface of the synchronous pressure roller
202 is pressed tightly against the roller surface of the seeding roller 201. The roller surface of the synchronous pressure roller 202 is made of materials with higher friction. While the synchronous pressure roller 202 rotates, the seed rope roller 201 is driven to rotate in the opposite direction through friction. The seed rope 217 is wound on the seed rope roller 201, and the seed rope 217 is released during the rotation of the seed rope roller 201. In the process of winding down the seed rope, in order to move the seed rope into the seed groove opened by the ditcher 7, a seed rope guide tube 216 is provided on the outer side of the seed rope 217, the seed rope guide tube 216 can guide the released seed rope directly below the ditcher 7.
[0032] The central rotating shaft of the synchronous ground wheel 214 is
connected with the synchronous ground wheel support rod 209, the upper outer side
of the synchronous ground wheel support rod 209 is provided with the synchronous
ground wheel positioning sleeve 210, the synchronous ground wheel support rod 209
is fixedly connected to the synchronous ground wheel positioning sleeve 210 through
two positioning bolts 211, the synchronous ground wheel positioning sleeve 210 is
fixedly connected with the frame 8, the end of the central shaft of the synchronous
ground wheel 214 is fixed on the sprocket I213, the end of the synchronous pressure
roller shaft 220 is fixed with the sprocket II 219, the transmission chain I 215 is
enwound around the sprocket I213 and the sprocket II219, the drive chain I215 is
connected with the tensioning mechanism 212. The tensioning mechanism includes an
L-shaped plate and a spring, the corner of the L-shaped plate is hinged with the frame
8, and at one end of the L-shaped plate is equipped with a roller, the roller is in
contact with the inner side of the transmission chain I215, and the other end of the
L-shaped plate is connected with the frame 8 through a spring. Under the action of the
spring, the L-shaped plate rotates, so that the transmission chain I 215 is always in
tension. In the invention, the diameter of the synchronous ground wheel 214 is the
same as the diameter of the synchronous pressure roller 202, the number of sprocket
teeth of the sprocket I213 and the sprocket II219 are the same; during the walking of
the synchronous ground wheel 214, the synchronous pressure roller 202 will be driven
by the chain drive to rotate at the same rotation speed and linear speed.
[0033] Two ditchers 7 are provided at the bottom end of the front of the frame 8.
As shown in Figure 3, the ditcher 7 comprises a main body 701 of the ditcher, a fixed
handle 702 for the ditcher, a connector for the covering device 703, a covering device
704 and a rope press wheel 705, the bottom end of the ditcher fixing handle 702 is
fixedly connected with the main body 701 of the ditcher by bolts, the top end is
fixedly connected with the frame 8 by the bolts; the rope press wheel 705 is arranged
on the inner side of the main body 701 of the ditcher and connected to the main body
701 of ditcher through its axle. One end of the covering device connector 703 is
hinged with the upper end of the main body 701 of the ditcher, and the other end is
hinged with the covering device 704.
[0034] The working principle of the invention is: after the engine 3 is started, the
power is transmitted to the gearbox 6 for speed change, and the rear roller 5 is driven
by the chain transmission device to push the entire machine forward. In the
forwarding process, the synchronous ground wheel 214 rotates and advances along
the seeding ridge surface, and drives the synchronous pressure roller 202 to rotate through the transmission chain I215. Under the pressing force of the coil spring 203, the long screw 205 generates a forward pulling force to make the pressure roller sliding U-shaped frame 207 has a tendency to move in the direction of the seed rope roller. In the process that the diameter of the seed rope roller 201 is continuously reduced, the roller surface of the synchronous pressing roller 202 will always be tightly pressed against the roller surface of the seed rope roller 201 under the elastic force of the spring 203. The roller surface of the synchronous pressing roller 202 is made of materials with relatively high friction, so the rotation of the synchronous pressing roller 202 will drive the seeding roller 201 to rotate in the opposite direction through friction. The seed rope wound on the seed rope roller 201 will be wound down, and the winding seed rope 217 enters the seed groove opened by the ditcher 7 through the seed rope guide tube 216, and is laid on the bottom of the seed groove under the pressure of the rope roller 705. The soil covering device 704 covers the seed trench and seed rope with the soil. Due to the diameter of the synchronous ground wheel 214 is the same as the diameter of the synchronous pressure roller 202, the number of sprocket teeth of the sprocket I213 and the sprocket II219 are the same, so the synchronous ground wheel 214 and the synchronous pressure roller 202 will rotate at the same rotation speed and linear speed. Because the synchronous pressing roller
202 drives the seed rope roller 201 to rotate, the linear speeds of the synchronous
pressing roller 202 and the seed rope roller 201 are same. That is, the linear speeds of
the synchronous wheel 214, synchronous pressure roller 202 and seed rope roller 201
are all equal, so under the action of the synchronous pressure roller, the linear speed of the seed rope from the seed rope roller is equal to the traveling speed of the machine. Therefore, it can be ensured that the seed rope is simultaneously broadcast into the soil. In the laying process of the seed rope, the drip tape rolls around the drip tape roll and laid it between the two rows of seed ropes, under the pressure of the rear roller and rolling forward. The groove in the middle of the rear roller limits the deviation of the drip irrigation tape to both sides.
