Description

  The present invention relates to a harvesting part of a harvesting and harvesting machine provided with a weeding body in a grain culm raising body.

Conventionally, when mowing, we cut the vegetation body at the shore in the retracted position where the weeds were retreated upward from the weeding position of the normal mowing work, so that hand mowing work (pillow cutting) The harvesting part of the combine that is reduced is already known (for example, Patent Document 1).
The weeding body of the reaping part is configured to be vertically movable (slidable) with respect to the culm raising body, and the upper part of the cerealing body can be rotated in the front-rear direction with respect to the reaping part frame. It has become.
In addition, by moving the weed body in the normal cutting operation to the front side with respect to the cereal raising body, it is switched to the overlaid vegetation posture in which the lying cereal is raised, so that The harvesting part which is made to harvest with the grain raising body by the taking over cutting blade is already well-known (for example, patent document 2).
The weeding body installed in the cutting part of the above-mentioned Patent Document 2 is inserted and supported by the inner and outer double cylinder structure so that the position of the weeding body can be changed with respect to the weeding frame of the cutting part frame, and the rear part of the weeding body is attached to the grain raising body side It is the structure which connects so that a grain candy may be relayed to the front-end | tip part of the elastic herbaceous body.
Japanese Patent No. 3449780 Japanese Utility Model Publication No.55-1147

The mowing unit shown in Patent Document 1 raises the weed body and rotates the culm raising body backward when performing a mowing operation (hereinafter simply referred to as a pillow mowing operation) for mowing the planted cereals along the shore. Since it is dynamically displaced, there is an advantage that the cutting blade is brought close to the shore without bringing the weed body into contact with the shore and the shore cutting is carried out, thereby reducing the manual pillow cutting work.
However, since the weed body is provided slidably with respect to the grain raising body, and the grain raising body is configured to be pivotally displaced with the upper part as a fulcrum, the weed load applied to the weed body during normal cutting operations is reduced. Since the cereal lumber is directly received, the reaping part needs to be reinforced, and the disadvantages such as a complicated and costly structure in which the cereal lure is rotated and displaced to the reaper frame. is there.
On the other hand, the mowing unit shown in Patent Document 2 fixes the cereals that are largely lying down by fixing them from the normal weeding posture in which the weed body is positioned rearward to the lying down weeding posture that has been moved forward. There is an advantage that weeds gently from the front and stand up without causing inconveniences such as ironing or pulling off the head.
However, this switching of the herb body to both postures is done by constantly monitoring the fallen state of the planted cereal while stopping the aircraft and temporarily stopping the combine work, and moving the herb body manually to fix it. There are drawbacks that must be made. In addition, the weed body has a problem that a large amount of pillow trimming work is required in a normal weeding posture because it causes uncut leaves when cutting along the shore.

Reaper harvester reaper of the present invention in order to solve the above problems, the first, the reaper frame, grain causing partial grass body and divided grass has been culms which divides grass planted culms the稈引force member provided at reaper of the culms that caused the cutting blade thus reap reaper harvester divides constituting the partial grass body supported on the reaper frame back and forth, grain稈引force member leave fixing the amount grass body located rearwardly against, provided movably minute grass body located forward in the longitudinal direction, the partial grass body under normal minute grass posture minute grass body located forwardly proximate the rear to the tip top of the partial grass body located rearwardly causes wrap, the wrap portion, that is provided with an inclined shape with a gap to permit rearward movement of the minute grass body located forwardly It is a feature.

Second, the biasing more forward minute grass body located in the forward Sprint grayed, more installed operating levers on the steering unit side, artificially shortened configured to enable partial grass body It is characterized by that.

  As described above, according to the present invention, by providing the weed body supported by the cutting part frame, the tip part is movable in the front-rear direction while fixing the rear part position of the weed body relative to the grain raising body, When cutting planted cereals along the shore, the tip part can be retracted to shorten the weed body, so that the cutting work with less pillow cutting work can be performed. It is possible to reliably guide the cereals from the weeds to the cereal body and cause the cereals to be raised smoothly.

  In addition, the cereals that stand up and weed in the front weeds that move back and forth are guided through the rear weeds that are supported in a fixed posture with respect to the cereals elicitors, so the cereals are raised from the weeds to the cereal elicitors Thus, it is possible to reliably perform the pulling action by the takeover grain raising body smoothly and to perform the cutting with the cutting blade in an orderly manner. In addition, when the front weed body is in contact with the shore or enters the ground, the contact load is released, so that it is possible to prevent damage or deformation of the weed body or the cereal-raising body.

  An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 is a combine provided with a weed body 2 according to the present invention, and a working unit such as a reaping part 3 and a threshing part 5 is provided on a traveling machine base 1 b provided with a crawler type traveling device 1 a. It arrange | positions in the front-back direction similarly to a thing, It becomes the structure which has arrange | positioned the control part 6 and the Glen tank 7 to the right side of the threshing part 5 behind the cutting part 3, and the waste cutter apparatus 8 behind the threshing part 5. ing.

  With this configuration, the planted cereals harvested by the reaping unit 3 are transported to the threshing unit 5 and threshed, and the threshed sorghum is cut by the staking cutter device 8 or remains in an uncut long state. To be discharged. In addition, the grain that has been threshed and sorted by the threshing unit 5 can be accommodated in the Glen tank 7 and subjected to a series of combine operations.

The cutting unit 3 rotatably supports the rear end of the cutting unit frame 9 on a support column standing on the front side of the traveling machine base 1b, and hydraulically supports the middle part of the cutting part frame 9 from the traveling machine base 1b side. It is supported by the cylinder so as to be movable up and down.
And the cutting part 3 provided the weeding body 2 and the grain raising body 11 in the front-back direction in the several weeding frame 10 extended from the cutting part frame 9 to the front side, and was sorted by the weeding body 2 (weeded). The planted cereals are raised by the raising claws 12 of the cereal erection body 11, and the cereals harvested by the cutting blade 13 in a stretched state can be conveyed toward the threshing unit 5.

  Next, the herbaceous body 2 will be described with reference to FIGS. In the illustrated weed body 2, a weed guide plate member forming a weed surface is divided into a front weed body 15, an intermediate weed body 16, and a rear weed body 17. The front side weed body 15, the intermediate weed body 16, and the rear side weed body 17 wrap ends of each other, and elastically urge the intermediate weed body 16 and the front side weed body 15 against the rear side weed body 17. It is configured to be able to expand and contract by operating forward and backward.

  That is, the rear weed body 17 is attached and supported on the upper portion of a bifurcated support member 20 that is erected at the tip of the weed frame 10 formed of a pipe rod. The intermediate weed body 16 is attached to and supported by an upper portion of a support member 22 erected at the tip of a middle weed frame 21 that is slidably inserted into the weed frame 10. The rear weed body 17 is provided integrally with a hook-like support member 25 provided at the tip of the front weed frame 23 that is slidably inserted and supported in the middle weed frame 21. The support member 22 is preferably formed of an elastic member that can be bent in the front-rear direction.

  Then, a helical spring 26 is inserted into the tip of the weed frame 10 and is positioned and supported by the support 10a, and the middle weed frame 21 is urged and biased to a predetermined weed position. In addition, a spring 27 having a lower elastic force than that of the spring 26 is inserted into the front end portion of the middle weed frame 21 and is positioned and supported by the receiving tool 21a, and the tip weed frame 23 is urged and biased to a predetermined weed position. is doing. Incidentally, the middle weed frame 21 and the front weed frame 23 are prevented from coming off to the front side by a retaining means (not shown).

  As shown in FIG. 2, the herbage 2 is in a normal weeding posture, and the rear portion of the intermediate weed body 16 wraps close to the top of the rear side weed body 17 and the rear portion of the front weed body 15 is the middle. It wraps above the tip part of the weed body 16, and each wrap part is provided with an inclined shape and a gap that allow the forward weed body to move backward.

  Further, the rear weed body 17, the intermediate weed body 16 and the front weed body 15 are all formed in a tapered shape with a downward semicircular arc shape (a saddle shape) cross section, and supported in a front downward slope shape in a side view, Side rotation of the intermediate weed body 16 and the front side weed body 15 around the weed frame axis is regulated through the lap portions. Incidentally, the side turning restricting means of the intermediate weed body 16 and the front side weed body 15 inserts the weed frame 10, the middle weed frame 21 and the front weed frame 23 together as a square pipe material so as to be slidable. You can also.

  And the weed body 2 is provided with the detection means 30 which detects the predetermined retreat of the front intermediate weed body 16 or the front side weed body 15. The detection means 30 in the illustrated example is mounted and supported on a mounting seat 31 provided on the support member 20, and when the sensor piece 32 protruded forward contacts the support member 22 by the retraction of the intermediate weed body 16, an ON signal Is sent to a control device (not shown) and alerted to the worker by an alarm or work stopping means to prevent work troubles associated with breakage or deformation of the weed body 2.

  The combine 1 provided with the cutting part 3 configured as described above is such that when the cutting part 3 is lowered and the combine work is performed while the combine 1 is traveling forward, Since the intermediate weed body 16 and the front weed body 15 are urged forward and extended by the springs 26 and 27 with respect to the rear weed body 17 fixedly supported on the front side of the reed body 11, the planted grain While raising the cocoon with the front weed body 15, the intermediate weed body 16 and the rear weed body 17 are erected, and the planted cereals are guided to the cereal body 11 by the rear weed body 17 while maintaining the standing posture. There is an advantage that it can be surely taken over, and the raising by the grain raising body 11 is always performed smoothly, and the cutting by the rear cutting blade 13 can be performed in an orderly manner.

  When cutting the planted cereals along the shore, if the tip of the front weed body 15 is brought into contact with the shore, the front weed body 15 and the intermediate weed body 16 retreat against the springs 26 and 27. Since the moving weed body 2 can be shortened, the rear weed body 17 raises the cereals that have been erected and cerealed without changing the takeover relationship of the rear part of the weed body with respect to the cereal body 11. While reliably relaying to the body 11, it is possible to mow the cereals closest to the shore in a state where the distance between the tip of the weed body 2 and the cutting blade 13 is reduced.

  Accordingly, it is possible to reduce the number of planted cereals left by the bank and reduce the labor of artificial pillow cutting. Further, when the tip of the weed body 2 comes into contact with a bank or the like or enters the ground, the front weed body 15 and the intermediate weed body 16 are sequentially retreated against the springs 27 and 26 to release the contact load. Therefore, it is possible to prevent and protect the herbage body 2, the cutting part frame 9, the culm raising body 11, and the like, and protect the herbage body 2 that expands and contracts when the load is released. Since it automatically returns, the cutting operation can be performed continuously without interruption.

Further, the herbaceous body 2 has an intermediate herbicidal body 16 and a front herbicidal body 1 with respect to the rear herbicidal body 17 as shown in the drawing.
5, the intermediate weed body 16 can be omitted, and the front weed body 15 can be urged and supported with respect to the rear weed body 17. 11 Grain the cereals with a gentle weed surface from the front of 11 and guide them to the cereal body 11 without squeezing or pulling off the head, and then wake up the cereals that have been erected. There is an advantage that the action can be performed smoothly.

  Further, the cutting unit 3 provided with the detection means 30 for detecting the retreat of the front side weed body 15 or the intermediate weed body 16 over a predetermined amount avoids the excessive contact of the front side weed body 15 by the detection signal of the detection means 30. In addition, it is possible to efficiently perform the cutting operation that prevents the cutting unit 3 from being damaged.

  For example, as shown by a dotted line in FIG. 2, the weeding body 2 is inserted into the weeding frame 10 by inserting a wire 39 provided on the operation lever 37 for expanding and contracting the weeding body installed on the control unit 6 side. 23 can be connected to the rear end. In this case, if necessary, by operating the operating lever 37, the pre-weeding frame 23 can be shortened by artificially retracting the pre-weeding frame 23 from the control unit 6 side. It is possible to avoid in advance that it touches the shore or enters the ground. Further, the expansion / contraction operation means of the weeding body 2 can use an electric motor with an operation switch instead of the operation lever 37.

It is the whole combine perspective view provided with the weed body structure of the present invention. It is a sectional side view which shows the structure of the weed body of FIG. It is a disassembled perspective view which shows the structure of the weed body of FIG.
