Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device. 2. Description of the Related Art Japanese Patent Application Laid-Open No. 2001-69846 discloses a structure in which a discharge auger for discharging grains temporarily stored in a Glen tank is made to be able to expand and contract. [0003] The auger cylinder A of the above-mentioned known example is formed to have the same diameter all the time, and as shown in FIG. 5, metal B is provided at both ends of a base and a tip thereof. Since the two parts, the tube A and the metal B, are used, a step, a gap, and the like are generated in a portion where the auger tube A and the metal B are attached, and there is a problem that this becomes a conveyance resistance. That is, since it is difficult to obtain the centering accuracy between the long fixed auger cylinder and the moving auger cylinder, the fixed auger cylinder A
If there is no gap between the outer periphery of the moving auger tube and the inner periphery of the moving auger tube, the fixed auger tube A is made thinner with respect to the moving auger tube in order to make this gap. If the diameter is reduced, another problem arises in that the area of the portion to be attached to the vertical fryer becomes small and the strength cannot be secured. So, to secure the strength,
If the fixed auger tube A is made thicker, the whole becomes thicker and the weight increases, so conventionally, the whole fixed auger tube A is made thinner, and a metal B is mounted thereon, and a mounting flange member C is provided on this. However, when the metal B is attached, as described above, the step between the auger tube A and the metal B attachment portion has a step.
A gap or the like is generated, and this becomes a conveyance resistance. However, if the structure of the fixed auger cylinder is devised, the problem of the conventional structure in which the metal is provided is solved, and a predetermined mounting area is secured, and the transfer resistance is reduced by eliminating steps, gaps, and the like.
In addition, after the step of integral molding by plastic working, subsequent processing for eliminating steps, gaps, and the like is not required, so that the number of steps and steps as a whole can be reduced, and costs can be reduced. [0004] It is an object of the present invention to reduce the weight of a telescopic discharge auger, to reduce transport resistance, to reduce the total man-hours, steps and costs. According to the present invention, there is provided a fixed auger 7 connected to a vertical fryer 5 for discharging grains in a Glen tank 4, and a movable auger 7 attached to the fixed auger 7 so as to extend and contract. The fixed auger 7 has one or both of a base portion and a distal end of the fixed auger tube 9 which are larger than the intermediate tube portion 9a of the fixed auger tube 9. Formed in a large-diameter cylindrical portion 9b having a large diameter.
And the intermediate cylinder portion 9a, an inclined cylinder portion 9c having a gradually decreasing diameter is formed, and the intermediate cylinder portion 9a, the large-diameter cylinder portion 9b, and the inclined cylinder portion 9c are integrally formed with a grain discharging device by plastic working. The grain that has been deeper-fed from the vertical fryer 5 enters the large-diameter cylindrical portion 9b of the fixed auger 7 from the metal 9e.
The grain that has flowed from the large-diameter cylindrical portion 9b into the inclined cylindrical portion 9c having a gradually decreasing diameter and has entered the intermediate cylindrical portion 9a from the inclined cylindrical portion 9c is conveyed by the fixed auger spiral 10, and then enters the moving auger 8, It is conveyed by the telescopic spiral 30 and discharged. [0006] According to the present invention, there is no flat resistance end surface having a step, and there is no portion that is a resistance to transportation.
Moreover, costs can be reduced by reducing the number of steps and man-hours. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 is a traveling device, 2 is a threshing device provided above the traveling device 1, and 3 is provided in front of a threshing device 2.

A fixed auger cylinder 9 is formed by plastically processing the intermediate cylinder 9a, the large-diameter cylinder, the large-diameter cylinder 9b, and the inclined cylinder 9c between the intermediate cylinder 9a, the large-diameter cylinder 9b, and the large-diameter cylinder 9c. (A method called basil processing by those skilled in the art). Therefore,
The inner peripheral surface of the fixed auger cylinder 9 can be formed as a flat end surface having no step, and does not generate a portion that is a resistance to conveyance. Reference numeral 9d denotes a mounting plate provided on the outer periphery of the large-diameter cylindrical portion 9b, and a connection portion between the base mounting plate 9d of the fixed auger tube 9 and the metal 9e of the vertical grain raising device 5 is known.
It is attached to the vertical frying device 5 so as to be able to rotate and turn freely on the horizontal axis. The fixed auger cylinder 9 is provided with a fixed auger spiral 10.
The fixed auger spiral 10 is mounted on an intermediate bearing 11 provided on the fixed auger cylinder 9. An outer bearing member 12 is provided on an outer peripheral portion of the fixed auger cylinder 9, and a distal end of a telescopic operation shaft member 13 is mounted on the outer bearing member 12, and a movable auger cylinder 14 of the moving auger 8 is mounted on the telescopic operation shaft member 13. The expansion / contraction receiving member 15 provided at an arbitrary portion of the above is screwed together, and the base side of the expansion / contraction operation shaft member 13 is connected to a driving member 16 constituted by a motor or the like provided on the outer periphery of the fixed auger cylinder 9. The telescopic actuating shaft member 13 is rotated by 16 to move the telescopic receiving member 15 back and forth in the longitudinal direction, thereby fixing the moving auger 8 to the fixed auger 7.
To expand and contract. The outer bearing member 12 has a base portion of a pair of right and left cover and support members 17 mounted on a flange-like mounting member 18 provided on the fixed auger cylinder 9 via a stay 19.
The distal end of the cover / support member 17 is attached to the distal bearing 20 via a stay 19, and the distal end of the telescopic operating shaft member 13 is mounted on the distal bearing 20. Left and right cover and support member 1
7 is to bend the upper part of the vertical plate 21 into an L-shape to form a bent portion 22, place the bent portion 22 on the stay 19, and place a flat mounting member 23 on the upper surface of the cover / support member 17, The member 23 is fixed to the stay 19 with a fastener 24 such as a bolt. Therefore, the stay 19 is fixed to each of the flange-shaped mounting member 18 and the front end bearing portion 20, and the stay 1 is fixed.
The upper bent portion 22 of the left and right cover and support member 17 is sandwiched from above and below by the mounting member 9 and the mounting member 23, and is detachably fixed by the fastening tool 24. Reference numeral 25 denotes a roller provided on the distal end bearing portion 20, which rolls on the outer periphery of the movable auger cylinder 14 and supports the distal end of the cover / support member 17. The moving end of the moving auger tube 14 is provided with a roller 2 which rotates in contact with the outer peripheral portion of the fixed auger tube 9.
7, the roller 27 is formed in an H shape when viewed from the front, and flange portions 28 are provided on the left and right sides. A flat plate-like guide member 29 is provided on the outer periphery of the fixed auger cylinder 9 between the flange portions 28. Thus, the fixed auger cylinder 9 and the movable auger cylinder 14
Is provided with a telescopic spiral 30. Assuming that the direction of expansion and contraction is “front and rear” for the sake of convenience, the expansion and contraction spiral 30 fixes a plate-shaped engagement member 32 which is long in the front and rear direction to the outer periphery of a cylindrical moving member 31 in the front and rear direction. Front-side engaging portions 33 and 34 are formed at the front and rear ends, respectively, and moving-side spiral blades 35 are fixed to outer surfaces of the front and rear ends of the engaging member 32 to move the moving spiral piece 36.
And the different diameter insertion hole 37 formed in the moving member 31 is inserted into the transmission shaft member 38 having the same outer peripheral surface. The transmission shaft member 38 is formed in a quadrangular or pentagonal polygonal shape, or a so-called oval shape or another different diameter shape. The moving spiral piece 36 is inserted into the transmission shaft member 38 in such a manner that the front engaging portion 33 and the rear engaging portion 34 on the front and rear sides of the engaging member 32 are engaged with each other. The rear engaging portion 34 of the base moving spiral piece 36 is engaged with the fixed auger spiral 10 side, and the leading moving spiral piece 36 is locked to the distal end side of the transmission shaft member 38 by an arbitrary method. Therefore, when the transmission shaft member 38 extends together with the moving auger cylinder 14, the most advanced moving spiral piece 36
Is pulled by the locking portion with the transmission shaft member 38, and then
The rear engaging portion 34 of the most advanced moving spiral piece 36 engages with the front engaging portion 33 of the rear moving spiral piece 36 and is pulled to move each moving spiral piece 36 with respect to the transmission shaft member 38. I do. The moving member 31 is formed shorter than the engaging member 32, and the moving spiral piece 36 engages the front engaging portion 33 and the rear engaging portion 34 on the front and rear sides of the engaging member 32 with each other. Since they are combined, each engagement member 32 is arranged so as not to overlap and as if to go around the outer periphery of the moving member 31,
In addition, the moving member 31 corresponding to the engaging member 32 that makes one round is in a contact state. This means that the moving-side spiral blades 35 are not continuous but overlap each other to form a set of moving spiral pieces 36, and the moving-side spiral blades 35 at the front and rear ends of the set of moving spiral pieces 36 are in a continuous state. Thus, a plurality of sets of the moving spiral pieces 36 exist in the axial direction of the transmission shaft member 38. The moving member 31 is connected to the cylindrical member 4.
0 at both ends of the transmission shaft member 38 in accordance with the shape of the transmission shaft member 38
Is fixed to the plate member 42 having. FIG.
Reference numerals 7 and 28 denote other embodiments of the moving member 31. The cylindrical member 40 is formed of a metal member, and small-diameter portions 4 are formed at both front and rear ends of the cylindrical member 40 by arbitrary means such as crushing.
3, and the small-diameter portion 43 is integrally formed with the insertion hole 41 conforming to the shape of the transmission shaft member 38. Thus, the base side of the transmission shaft member 38 is slidably fitted to a fixed spiral rotary shaft 39 mounted on the intermediate bearing portion 11. In this case, the moving member 31 of the moving spiral piece 36 at the start end of the moving spiral piece 36 is fitted into a fitting hole 47 formed on the front side of the bearing 46 in the outer cylinder 45 of the intermediate bearing portion 11. A member 48 is provided (FIG. 29). That is, the fitting member 48 is fitted almost tightly to the inner periphery of the outer cylinder 45 to prevent the grain from entering the intermediate bearing portion 11. The lateral discharge auger 6 is placed and stored on an auger receiver 49 provided at an arbitrary part of the fuselage, and the auger receiver 49 is provided with a receiving roller 51 at a lower portion between the bifurcated upwardly projecting arms 50. (See FIG. 3)
0). In this case, when the lateral discharge auger 6 is stored in the auger receiver 49, when the lower surface of the lateral discharge auger 6 abuts on the receiving roller 51, the side surface of the lateral discharge auger 6 does not contact the inner surface of the arm 50. The configuration described above is preferable because both the outer peripheral surface of the lateral discharge auger 6 and the auger receiver 49 can be prevented from being deformed. In the Glen tank 4, there is provided a transport discharge device 55 for transporting and discharging the grains in the tank 4 toward the vertical frying device 5 (FIG. 31), and a pulley for transmitting rotation to the transport discharge device 55. The transmission of the rotation from the engine (not shown) is transmitted to the 56 via a transmission (not shown) capable of changing the speed, so that the discharge amount of the grain from the Glen tank 4 can be freely changed. To be configured. The rotation from the vertical fryer 5 is transmitted to the horizontal discharge auger 6, and the end of the transport and discharge device 55 is connected to the lower part of the vertical fryer 5 and discharged by the transport and discharger 55. And the pulley 57 at the lower part of the vertical-graining device 5 is driven by a rotation transmission mechanism (not shown) provided separately from the conveying / ejecting device 55 to produce the engine. , The rotation that does not resonate the lateral discharge auger 6 (the rated rotation of the engine). In this case, when the start of the grain discharge operation is confirmed (detected) by the operation of the transport / discharge device 55 or the vertical grain raising device 5 or the like, the output rotation (the rated rotation of the engine) is performed so that the engine does not resonate the horizontal discharge auger 6. In this case, the operability is improved, which is preferable. It is preferable that the horizontal discharge auger 6 is configured to exhibit a discharge conveyance force equal to or higher than that of the vertical fryer 5, since it is possible to prevent the occurrence of grain clogging. FIGS. 32 to 34 show another embodiment, in which the conveying and discharging device 55 includes a conveying spiral 6 in a receiving gutter 60.
1, and above the receiving gutter 60, there is provided an adjusting body 62 for adjusting the amount of grains entering the receiving gutter 60. 63 is an actuator for opening and closing the adjusting body 62. In the case of the above-described embodiment, when the rotation of the engine is equal to or less than a predetermined rotation, the lateral discharge auger 6 is provided with any of the discharge clutches (each of the transport discharge device 55, the vertical grain raising device 5, and the horizontal discharge auger 6). Even if the engine is turned on (not shown), the engine is controlled not to perform the discharging operation when the rotation of the engine is equal to or less than the predetermined rotation, thereby preventing the occurrence of resonance when the lateral discharge auger 6 is extended. In this case, when detecting the discharge operation when the rotation of the engine is equal to or less than the predetermined rotation, a display unit provided at an arbitrary position (for example,
It is preferable that the alarm is displayed on a lamp or a liquid crystal display) and further an alarm is sounded to notify the operator of the erroneous operation. (Operation of Embodiment) Next, the operation will be described. The machine is run, the culm in the field is cut by the reaper 3 and threshed by the threshing device 2, and the threshed grains are stored in the Glen tank 4. The grain is ground and discharged by the lateral discharge auger 6 to a truck tank near the field. Since the horizontal discharge auger 6 is formed by the fixed auger 7 connected to the vertical fryer 5 and the movable auger 8 attached to the fixed auger 7 so as to extend and contract, the horizontal discharge auger 6 is driven by a motor or the like. When the telescopic operating shaft member 13 is rotated by the member 16, the telescopic receiving member 15 screwed to the telescopic operating shaft member 13 moves with respect to the fixed auger 7, thereby expanding and contracting the moving auger 8, and the lateral discharge auger. It becomes easy to align the tip of 6 with the tank of the truck. When the discharge operation is completed, the horizontal discharge auger 6 is stored in a reduced size, and the next operation is resumed.
It does not hinder work and improves workability. in this case,
The fixed auger cylinder 9 and the movable auger cylinder 14 are configured to be expanded and contracted by being overlapped with different diameters from each other, and a roller 27 is provided at the base of the movable auger cylinder 14, and the roller 27 is formed in an H-shape in a front view. A flange 28 is provided on the left and right, and a flat guide member 29 provided on the outer periphery of the fixed auger cylinder 9 is fitted between the left and right flanges 28. The action prevents rotation of the moving auger cylinder 14 and smoothly expands and contracts. Since the guide member 29 is formed by a simple flat plate member, it may be fixed by welding at several places in the length direction, and the deformation can be reduced and the cost can be reduced. Further, the outer bearing member 12 is stopped by vertically sandwiching a pair of right and left cover / support members 17 by stays 19 and mounting members 23 fixed to the flange-shaped mounting member 18 and the distal end bearing portion 20, respectively. Since it is detachably fixed by the clothing 24, the number of parts is reduced and the cost is reduced. The moving member 31 having a cylindrical shape in the front-rear direction, a plate-shaped engaging member 32 fixed in the outer periphery of the moving member 31 in the front-rear direction, and a moving-side spiral fixed to outer surfaces of both front and rear ends of the engaging member 32. Spiral piece 3 moved by wing 35
6, the front and rear engagement portions 33 at the front and rear ends of the engagement member 32 of each moving spiral piece 36 are sequentially inserted through the transmission shaft member 38 so as to engage with each other. 3
0 is provided in the fixed auger cylinder 9 and the movable auger cylinder 14, so that when the movable auger cylinder 14 is extended, the movable auger cylinder 14
The moving spiral piece 36 on the distal end side moves with respect to the transmission shaft member 38 until the rear engaging portion 34 pulls the front engaging portion 33 of the rear moving spiral piece 36, and the rear moving spiral piece 36 moves. The moving member 36 moves with respect to the transmission shaft member 38 until the front engaging portion 33 of the moving spiral piece 36 on the rear side is pulled, and this movement is repeated, so that the interval between the moving spiral blades 35 of each moving spiral piece 36 ( The pitch increases, and the telescopic spiral 30 also extends in accordance with the extension of the moving auger cylinder 14. The transmission shaft member 38 is formed in a quadrangular or pentagonal polygonal shape, or a so-called oval shape or the like having different diameters.
Since the different diameter insertion holes 37 formed in the moving member 31 of the moving spiral piece 36 are inserted through the transmission shaft member 38, each moving spiral piece 36 moves in the axial direction of the transmission shaft member 38,
When the transmission shaft member 38 rotates, the moving-side spiral blade 35 of each moving spiral piece 36 rotates to convey the grain. The fixed auger 7 of the lateral discharge auger 6 is
A large-diameter tube portion 9b having a larger diameter than the intermediate tube portion 9a of the fixed auger tube 9 is formed on one or both of the base and the tip of the fixed auger tube 9, and between the large-diameter tube portion 9b and the intermediate tube portion 9a. An inclined cylindrical portion 9c having a gradually decreasing diameter is formed, and the intermediate cylindrical portion 9a, the large-diameter cylindrical portion 9b, and the inclined cylindrical portion 9c are integrally formed by plastic working. No machining such as shaving is required, and a significant cost reduction can be realized.In addition, since it is integrally formed by plastic working,
The inner peripheral surface of the fixed auger cylinder 9 can be formed as a flat end surface having no step, thereby reducing the transport resistance, and also reducing the overall distortion and also reducing the transport resistance of the grain. That is, conventionally, the reason why the fixed auger cylinder is not always formed to have the same diameter at all times and metal is provided at both ends is that if the gap between the front side of the fixed auger cylinder and the inner periphery of the movable auger cylinder is reduced, the whole becomes thicker. Therefore, even if the entire fixed auger cylinder is made thinner, it is difficult to obtain the centering accuracy between the long fixed auger cylinder 9 and the movable auger cylinder, and smooth expansion and contraction cannot be expected. Further, although the diameter of the base of the fixed auger cylinder is small and the area of the mounting portion is small, the mounting area is secured by providing a metal having a larger diameter than the fixed auger cylinder 9. However, in the conventional configuration in which the metal is provided, since there are two parts, steps and gaps are generated in the mounting portion, which has a problem of being a transport resistance, but the present invention solves this and secures a predetermined mounting area. In addition, steps and gaps are eliminated to reduce transport resistance. Further, after the step of integral forming by plastic working, post-processing for eliminating steps, gaps and the like is not required, so that the number of steps and steps as a whole are reduced, and the cost is reduced. The grain which has been further raised by the vertical fryer 5 enters the large-diameter cylindrical portion 9b of the fixed auger 7 from the metal 9e, and flows from the large-diameter cylindrical portion 9b into an inclined cylindrical portion 9c having a gradually reduced diameter. The grains that have entered the intermediate cylinder 9a from the inclined cylinder 9c are conveyed by the fixed auger spiral 10 and discharged. In this case, the boundaries of the large-diameter tubular portion 9b, the inclined tubular portion 9c, and the intermediate tubular portion 9a (the same applies in the order of the intermediate tubular portion 9a, the inclined tubular portion 9c, and the large-diameter tubular portion 9b) are integrally formed. As a result, there is no portion that becomes a flat end surface with no steps and becomes a resistance to transport, and the kernel is transported smoothly. Thus, the moving member 31 of the telescopic spiral 30
Is formed by fixing a plate member 42 having an insertion hole 41 corresponding to the shape of the transmission shaft member 38 at both ends of the cylindrical member 40. This eliminates the need for a significant cost reduction. Further, the insertion hole 41 may be formed in the plate member 42, and the manufacturing accuracy is further improved, and the sliding contact resistance between the transmission shaft member 38 and the insertion hole 41 is reduced. Also, generation of abnormal noise is suppressed. When the plate member 42 is formed of stainless steel, the plate member 42
Rust on the sliding surface with the transmission shaft member 38 can be prevented without painting, and the conventional moving member 3 is machined out of iron material.
As compared with the first method, the painting process is not required, and the cost can be reduced. In another embodiment of the moving member 31 shown in FIGS. 27 and 28, a small diameter portion 43 is formed at both front and rear ends of the cylindrical member 40 by means such as crushing the cylindrical member 40 with a metal material. Since the small diameter portion 43 is formed integrally with the insertion hole 41 conforming to the shape of the transmission shaft member 38, there is no need for the step of cutting out a thick metal cylinder as in the related art, resulting in a significant cost. Down can be realized and the plate member 4
The insertion accuracy can be further improved, the sliding contact resistance between the transmission shaft member 38 and the insertion hole 41 can be reduced, and the generation of abnormal noise can be suppressed. Then, the telescopic spiral 3
The base side of the transmission shaft member 38 for rotating the zero moving member 31 is slidably fitted on a fixed spiral rotating shaft 39 mounted on the intermediate bearing portion 11, and the moving spiral piece 36 at the start end of the telescopic spiral 30 is formed. The moving member 31 is provided with a fitting member 48 that fits into a fitting hole 47 formed on the front side of the bearing 46 in the outer cylinder 45 of the intermediate bearing portion 11. It fits almost tightly around the circumference to prevent grain from entering the intermediate bearing portion 11. That is, conventionally, a sealing member formed separately from the telescopic spiral 30 is mounted on the intermediate bearing portion 11 to prevent the intrusion of grains, but the moving member 31 of the moving spiral piece 36 at the start end is Since the moving spiral piece 36 at the distal end is elongated by being originally located near the intermediate bearing portion 11, the fitting member 48 provided on the moving member 31 of the moving spiral piece 36 at the starting end is replaced with the intermediate bearing portion 11. When fitted into the fitting hole 47 of the outer cylinder 45, not only the intrusion of grains but also the fixed structure for stopping the expansion and contraction movement of the moving spiral piece 36 at the start end is rationalized. Become. An auger receiver 49 for mounting and storing the lateral discharge auger 6 is provided at an arbitrary portion of the fuselage.
Since the receiving roller 51 is rotatably mounted on the lower part between the forked arms 50, when the lateral discharge auger 6 is stored in the auger receiver 49, the lower surface of the lateral discharging auger 6 is placed on the receiving roller 51. Since the side surface of the lateral discharge auger 6 is not in contact with the inner surface of the arm portion 50, deformation of the outer peripheral surface of the lateral discharge auger 6 and the auger receiver 49 can be prevented, which is preferable. In this case, since the receiving roller 51 is rotatably mounted on the shaft, even if the lateral discharge auger 6 is expanded and contracted while being stored in the auger receiver 49, the lower surface of the lateral discharge auger 6 slides on the receiving roller 51. Prevents problems such as peeling of paint without contact. Then, the tank 4
A transport discharge device 55 for transporting and discharging the grains in the vertical direction to the vertical fryer 5 is provided, and a pulley 56 for transmitting rotation to the transport discharge device 55 is connected to a pulley 56 via a transmission capable of shifting the rotation from the engine. The transmission from the vertical lifting device 5 is transmitted to the horizontal discharge auger 6 by a speed change transmission, and the pulley 57 at the lower portion of the vertical lifting device 5 is transmitted by a rotation transmission mechanism provided separately from the transport discharge device 55. Since the rotation that does not resonate the lateral discharge auger 6 is transmitted from the engine, the amount of the kernel discharged from the Glen tank 4 can be freely changed by changing the transmission rotation to the conveying / discharging device 55, and the lateral discharge auger 6 can be freely changed. The discharge auger 6 does not resonate. That is, if the rotation transmitted to the lateral discharge auger 6 is low, the lateral discharge auger 6 resonates, so that it is necessary to constantly transmit a rotation of a predetermined rotation or more. It is impossible to change the discharge amount of the grain by lowering the rotation of the auger. However, by adopting the above configuration, both the change in the discharge amount of the grain and the prevention of the occurrence of resonance of the lateral discharge auger 6 are compatible. In another embodiment of FIGS. 32 to 34,
The conveying and discharging device 55 is configured by providing a conveying spiral 61 in a receiving gutter 60, and an adjusting body 62 for adjusting the amount of grains entering the receiving gutter 60 is provided above the receiving gutter 60. Even if a conventional transmission path for transmitting rotation from the device 55 to the horizontal discharge auger 6 via the vertical fryer 5 is used,
By transmitting rotation that does not cause the lateral discharge auger 6 to resonate, the occurrence of resonance of the lateral discharge auger 6 is prevented, and
The adjustment of the amount of grains entering the receiving trough 60 by means of 2 makes it possible to simultaneously change the amount of discharged grains.
