Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seeding machine used for sowing seeds in a field.

(Prior art and its problems) The present invention is equipped with a furrowing device that forms a trench for seeding in a field, and a seeding device that appropriately feeds seeds stored in a hopper and supplies them into the trench through a seeding tube. A seeding machine that sows seeds in a field while being towed by a sowing machine is in practical use. Many of these types of seeding machines have a V-shaped furrower and form furrows by pushing it into the field and towing it. When the suspended aircraft is lowered to the ground, a large amount of soil enters the inside of the V-shaped groove maker, making it impossible to form the desired groove, and the inside of the groove formed by the groove maker becomes visible. They often clogged the seeding tubes that were installed in the same way. A serious problem arose in that if the seeding tube became clogged, normal seeding could no longer be carried out.

(Object of the Invention) The present invention was made in view of the above circumstances, and its purpose is to prevent a large amount of soil from entering the trencher at the start of work.

(Structure of the Invention) The seeding machine according to the present invention includes a groove making device that is inserted into a field and moved to form a groove for seeding, and a seeding device that appropriately feeds out seeds in a hopper and supplies them to the field.

A mouth member 26 is attached to the lower end of the seeding tube 25. The dispensing device 22 includes a dispensing roll 27 having a groove formed on the outer periphery for the seeds to enter, and the rotation of the dispensing roll 27 causes the seeds in the hopper 21 to be dispensed downward in appropriate amounts. At the bottom of the mouth member 2B,
A shutter 30 is provided that opens and closes when the sensor 28 moves downward.

Seeds dispensed from the dispensing port 22a of the dispensing device 22 are introduced from the receiver 23 into the seeding tube 25, pass through the mouth member 26, and fall into the field.

A horizontal bar 33 made of a hexagonal par is fixed to the front end of the machine frame 13. A mulching device 35 is installed at the rear of the horizontal bar 33.
A support frame 37 is fixedly attached. At the lower end of the support frame 37, a roll 39a of a sheet I-39 for mulching is supported 5, and at the middle part of the support frame 37, a support is provided so as to surround the sheet roll 39a. Part 4
0 is fixed. The sheet 39 is a perforated sheet in which sowing holes 39b are bored at regular intervals, and the rows of the holes 39b are formed by the sowing device so as to overlap the grooves formed by the groove making device number. A number of them are arranged in parallel. A groove cutter 41 is attached to one end of the support member 40, and a sheet guide 43 is attached to the other end to hold down the upper surface of the sheet fed out from the sheet roll 39a and guide it to the lower side of the opening member 26. installed. The groove cutter 41 is formed into a generally V-shaped boat shape in plan view and front view, and its front end is attached to the support member 40 with the rear end being inclined at a lower position. A soil cover plate 44 extending rearward is attached to the rear part of the furrower 41, if necessary, so as to cover the furrow after sowing. Note that the mouth member 26 is provided so as to face the inside of the groove creator 41. An arm 45 that hangs downward is attached to the machine frame 13 at a position slightly in front of the seeding device 20, and a sheet presser 47 that presses down the sides of the sheet 39 is attached to the lower end bent forward. ing. Furthermore, a chain case 52 that supports the rotating shaft 51 of the pressure roller 50 and a bearing member 53 provided on the opposite side of the chain case 52 are pivotally attached to the machine frame 13 .

Inside the chain case 52 is a rotating shaft 51 of the pressing roller 50.
A chain is built in to transmit the rotation of the sowing device to the feed-out roll 27 of the seeding device, and the feed-out roll 27 is driven by a pressure roller 50 that rotates due to the resistance received from the ground during traction.

An elongated hole 55 is bored in the rear vertical member 7 of the parallel link device 3, which has an opening shape in plan view, and a pin 56 for pivotally connecting the upper member 9 is slidably fitted into the elongated hole 55. are doing. Further, a fitting 57 is provided on the upper surface of the rear end of the second member 9 and projects upward, and a rounded triangular cam type stopper 59 constituting a locking device 58 is pivotally attached to this. A torque spring 61 is fitted onto a shaft 80 that rotatably supports the stopper 58, and the stopper 59 is always urged by the torque spring 61 to rotate in the direction of arrow X. A wire 63 for pulling back the stopper 59 in the opposite direction of the arrow X is connected to the stopper 59 , and the opposite end of the wire 63 is connected to an operating lever 65 .

When carrying out work using this seed sowing machine 1, the entire machine body including the mulching device 35 is towed via the connecting hitch 2 and moved around the field. As the machine moves forward, grooves are formed in the field by the groove making machine 41, and the sheet roll 3
Seeds 39 are fed out from 9a and placed over the field. At this time, when the hole 39b of the sheet 39 comes directly under the mouth member 26, the sensor 29 falls into this hole 39b, opens the shank 30, and drops the seeds sent through the seeding tube 25 into the hole 39b. The rows of holes in the sheet 39 are arranged so as to overlap the grooves formed by the trencher 41, so the seeds fall into the formed grooves and are covered with soil by the covering soil plate 44. At the same time, the sheet 38 is placed so that the hole 38b is located at the seeding position. The fixation after seeding is suppressed by a pressure roller 50.

Next, when the machine is lifted during a turn, etc., the rear of the machine moves downward due to gravity, and the groove cutter 41 and mulching device 35 attached to the front of the machine frame 13 move upward. Pin 5θ for lower member 10 pivot
The aircraft rotates around ′. Then, the rear vertical member 7 to which the machine frame 13 is attached rotates in the direction of arrow Y.
Since the pin 56 is located at the front end of the elongated hole 55 and the upper part of the rear vertical member 7 opens, the striker 59 rotates in the direction of arrow , and the rear vertical member 7 is locked in a downwardly rotated state together with the fuselage. Therefore, even if one machine is lowered to the ground, the front part of the machine remains high and the rear part low, as shown in Figure 3, and the groove cutter 41, mulching device 35, etc. are lifted off the ground. It is kept in a sharp state. This prevents an accident in which multi-needle soil enters the inside of the furrower 41 before the normal work starts, preventing normal sowing.

Next, when the operating lever 65 is operated to pull the wire 63, the stopper 58 rotates in the direction opposite to the arrow X and deviates from between the pin 56 and the rear vertical member 7, so that the rear vertical member 7 The aircraft rotates in the Y direction and returns to its normal horizontal position. Therefore, normal work can be performed.

(Effects of the Invention) As is clear from the above explanation, the seeding machine according to the present invention is effective in preventing accidents such as when a large amount of soil enters the planting device immediately after turning, etc., and normal seeding cannot be performed. It has become possible to prevent this.
