Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shutter device for a feeding machine such as a seeding machine or a fertilizer applicator, and in particular, it is capable of immediately stopping feeding while the feeding roll remains rotationally driven. The number of bases can be freely selected, making the feeding work more efficient and reliable.

For example, in a flooded direct sowing machine, multiple feeders are connected in series to achieve efficient seeding work.

In this case, if the feeding row μ is rotationally driven, the seedlings are fed out without fail, so there is an inconvenience that all the multiple rows always sow seeds. As a result, depending on the situation of the rice field, it may be necessary to sow all of the seeds even if only a portion of the multiple rows are needed.As a countermeasure, a shutter is constructed as a countermeasure, but its switching responsiveness is temporary. However, there were some inconveniences such as seeds remaining between the shutter and the feed roll and being sown after the same.

This invention was created in view of these circumstances, and therefore, the feature here is that an adjustment pusher is placed on the outer periphery of the feed-out roll μ, and the product is guided and guided to the feed-out roll through the pusher. In order to freely open and close the guiding path, a shutter ft is provided which can move forward and backward with respect to the adjustment pusher side.

The present invention will be described below with reference to an illustrative embodiment.

Figures 1 to 5 show an example of a flooded direct seeding machine.

(1) is a direct seeding machine traction machine, and the traction machine (1) has a chassis (2) in the center and an engine (3) mounted on the front end of the chassis.The engine (3) faces backward from both measuring parts. A pair of running transmission cases (4) are stretched out from the top, and a pair of running wheels (5) are provided thereon in a freely drivable manner. In this way, the engine bonnet) (61t- is covered and the traction machine 70-) (7) f is attached to the front part of the lower concave part, and is configured to be steered rearward for these steering purposes. It comprises means (8).

(9) is a gear case fixed to the back of the chassis (2).Into the case (9), the power take-off shaft αq provided through the chassis (2) is guided as an input, and in this way, the rear flooded direct seeding The main machine αD is driven.

This sowing machine I consists of an upper seed hopper U, a dispensing case 6υ below it, a sowing chute α3 below it, a front bracket α4 protruding from the front of each dispensing case 0υ, and a chassis ( 2) Rear placket α protruding from the side
9 are connected to each other, and in this case, the
In order to stabilize the hopper support α11, a hopper receiver α11 is installed upright from the second gwocket (14+).

Further, a link fixed support frame 0 force is vertically installed on the front placket α4, and a link movable support frame (A) is attached to it via a parallel link Og with a bullet lowering mechanism (to), and a work machine float shaft υ is installed. It consists of Each of these flows) 021) The bottom surface has a leading grooving guide plate ■ in the center, and a grooving plate (23 is arranged, 6□□□ is the 7m-) at the rear center of the leading groove cutting guide plate ■) standing at the tail end of C2D. A ground leveling plate (A) having a soil covering and leveling function is installed on the ground leveling plate Zaboto, which has soil covering and leveling functions via a lowering mechanism.

As shown in Fig. 2, this type of direct seeding machine has four units connected in parallel on the left and right, and they are simultaneously driven by a common shaft-type feeding drive shaft. The sprocket and drive shaft are interlocked with the drive sprocket in the center of the foot.

A detailed explanation of the feeding device driven by the Uami is as follows.

The detailed rules for the handle are as shown in Figs. 3 to 5. The above-mentioned nine dispensing case 6N) is a case that opens downward, and the dispensing case body (6N), which is in communication with the hopper 〇3, is located in the center of the interior of the case. 81a) f: Fixed in a hanging type.

The main body of the case (sea) has a front and back thick feeding guide section at the top and a seeding chute σ3 at the bottom end, and a large set of feeding rolls (to) with a forward/backward adjuster C3a are rotatably incorporated into these parts. The width of the variable feeding groove (2) formed in the center can be freely adjusted.

This variable feed groove (■) faces the adjustment pusher (to) from the front, and in this case, the pusher attachment plate wt. At the same time, a holding plate @ is applied from the bottom side and it is attached with bolts θO so that it can be freely adjusted back and forth.Here, in addition to the front and rear adjustment, an arc-shaped opening/closing guide groove is formed on the side wall of the feeding case 0υ, and the brush support shaft ( The opening/closing lever (44) that hangs in a bent shape from
With the lock knob nut +431, the swing can be freely adjusted. In the upper position shown in Fig. 3, the material from the hopper ■ is guided sequentially to low/L' (to), while in the lower position, the material is guided. It is structured so that it can be removed by independent operation.

In the case of grain, there is a nine hopper that guides the feed to the central variable feed groove.■ An L-shaped control plate F441 is protruded from the lower part, and a focusing guide port (44B
) The feeding means is constructed as described above, but here, even if each direct sowing machine is in the driving state, each machine can independently stop feeding and return to the feeding position. The shutter [4151] is configured.

In this case, an obliquely oriented insertion tube 1461 is protruded from the rear of the upper surface of each feeding case 0υ, and the shutter support shaft (4 forces) is inserted and supported through the cylinder @ ink pad so that it can be freely inserted and removed up and down.

A shutter plate (t4E9) is protruding from the lower end of the same support shaft U sword, and the plate (481) is in a relationship that approaches the push. Pin holes H91Q formed in each of the insertion tubes [4[j]
5o) e It is latched and locked by the beta pin 0511, and can be locked in the open state via the elevation knob at the raised height position.

In addition, the shutter 7° rate is the adjustment brush (2) in the illustration.
Although it is said to be a type close to the same type, it is free to attach and support it to the same pufushi (to), and this can prevent wear and tear on the V-yutter (45).

With the above structure, the shutters 4 can be opened and closed independently and freely in each group, so that part or all of the feed rolls can be freely controlled even when the feed rolls are in operation. Especially when the number of threads is reduced after turning, the possibility of remaining between the feeding rows A/(to) can be reduced because it is closed by approaching or contacting the pusher (to) as described above. This also eliminates the mistake of firing the ball even though it has been shut. In addition to its guiding function, the brush stroker also has a function of scraping the inside of the variable feed groove G◆.

This invention is as described above, and therefore the feeding row A/ is rotationally driven! It is possible to stop the feeding of each unit independently up to υ, for example, as in the above embodiment, the number of feeding units of the multiple unit feeding machine can be set to only a necessary part or all units can be stopped, and the actual It has now become possible to realize efficient and accurate feeding work that perfectly matches the work situation.

In addition, what is additionally illustrated in Figure @2 is the basic base, for example, a four-row direct seeding machine (111, with an extension direct seeding machine αDlffi attached on both the left and right sides, so that it can take an avoidance posture by rotating and swinging as appropriate. - A high fixed support plate (54) (c) 4) is erected at both ends of the mounting bar (f) that is suspended horizontally on the front or rear side of the direct seeding machine αD with four tamps. Two extension direct seeding machines OB' each on the left and right sides are pivotally supported by extension bars OB' supported via fulcrum rollers (55), and a mounting plate (57
``If: Fixed support plate (54) K pin to complete the working posture. Avoidance posture is to first line up the lower manut wolf 8) which forms an upright shape along the fixed support plate (54), and then attach the upper end. This is achieved by rotating the inward direction t!90 degrees and fixing the mounting plate @η.Thus, the extension direct seeding machine 011' can be retracted in a very compact manner when it is not needed, while at the same time, when it is needed, it can be (It can be easily set up for sowing. In this case, if the turning radius allows, the position of the lower fulcrum roller (5) can be used as a pivot axis to allow the center trap to rise and fall freely. Similarly, the base plate -° can be folded forward or upward via a hinge (59) f.Furthermore, the extension shaft f61 is detachable via a joint (6υ).
