Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a beltless bucket elevator for grain.

(Mitsuki technology) Conventionally known Japanese Patent Publication No. 53-4308 (Figs. 1 to 3)
(shown in the figure) has a lower guide wheel B in the support frame cylinder A.
, and an upper guide wheel C, and between the guide wheels B and C, there is an endless bell (E) with a large number of buckets D attached inside.
A bucket elevator is described in which the grains accumulated between the lower guide wheels B are scooped up and fried by the buckets D.

Furthermore, the conventionally known Japanese Patent Publication No. 54-33992 describes a technique in which grains fried by a bucket elevator are transported horizontally and laterally by a horizontal spiral conveyor.

(Problems to be Solved by the Invention) Known bucket elevators, not only the above-mentioned known examples, all use a belt and have a structure in which a bucket is attached to the belt. That is, it has a structure in which an endless bell (E) is hooked between a lower guide wheel B and an upper guide wheel C provided under -A, and buckets D are attached to the endless bell (H) at a constant interval. . However, when attaching the bucket D to the endless belt H, a bolt is integrally provided on the back side of the bucket D, a reinforcing plate is installed between the bucket D and the endless belt E, and the bolt is reinforced. The bolt is passed through a plate and a belt and projected to the opposite side, a presser fitting and a washer are fitted onto the protruding portion of the bolt, and the bolt is tightened and fixed with a nut, so the installation work is extremely troublesome.

In addition, the known bucket elevator has a structure that lifts the grain to a predetermined position above or diagonally above the grain, and when the grain is to be transported laterally after being hoisted, a separate spiral conveyor for traversing is required. There was an issue.

In addition, since the known bucket elevator has a structure in which a certain amount of stored grain is scooped up by a bucket and then fried, the bucket cannot be made very large, and is at most the size of a thick cup. The grain frying efficiency per bucket was low. Therefore, in order to speed up one rotation and ensure efficiency, the discharge state becomes close to the home state, resulting in damage to the grain. Not only that, but the surface of the grain is very hard, so especially in the case of unhulled rice, the receiving trough itself that receives the unhulled rice is subject to severe wear, creating the problem of raising the grain while making a lot of noise.

In addition, the bucket passes through the accumulated grain layer and scoops up all the grain before ascending the hill, so it is constantly overflowing and spilling as it ascends the hill.

In order to have a structure in which this spilled grain is collected in the lower part without scattering and scooped up again, the supporting frame cylinder A shown in FIG. 1 is required. This support frame? 1iIA is.

Regardless of whether they are made of metal or wood, they are surprisingly expensive and account for most of the cost of a bucket elevator, making the bucket elevator expensive.

Also, since the bucket passes through the accumulated grain layer and scoops it up, the grain may be damaged at that time.
Also, since the grain below the line where the bucket passes is not scooped out, there is always residual grain. And the remaining grains.

Since it is not necessarily metabolized and often remains forever, when a bucket elevator is attached to a dryer for circulation drying, there is a problem that some material is not dried at all, resulting in uneven drying.

However, with the following configuration, the buckets can be formed one by one and connected one after another to form a connected body, resulting in a beltless bucket and the installation effort can be omitted. In addition, since the raised grain can be moved laterally as it is, a spiral conveyor for traversing is not required, and costs can be reduced when forming a circulation type rice milling device.

Furthermore, when feeding grain into the bucket, the idea is to pour it into the bucket instead of scooping it into the bucket as in the conventional method, so all of the above-mentioned problems can be overcome.

Additionally, the bucket can be made at least several times as large as the conventional bucket, so if the rotation speed is kept the same as before, the efficiency will be several times greater, and the bucket can be rotated slowly and quietly.

Also, if the bucket has a lid, it will prevent spillage during transportation.
can be

(Objective of the Invention) The object of the present invention is to form individual buckets and connect them to form a beltless bucket elevator, which is a bucket elevator, and to prevent grain spillage during grain frying. That's what I did.

(Means for Solving the Problems) The present invention connects buckets with lids 19 one after another between the lower guide wheel 2, the upper guide wheel 4, and the upper front guide vehicle 3, which are mounted on a support frame 1. The endless continuum is wound around a bucket endless continuum, with the part that rotates the lower guide wheel 2 serving as the feeding blade, and the part from the lower guide wheel 2 to the upper crosspiece guide wheel 4 on the upward stroke (into, The period from the upper guide car 4 to the upper front self-vehicle 3 is the discharge stroke sum, and the period from the upper front self-vehicle 3 to the lower guide vehicle 2 is the downward stroke 41. This is a beltless bucket elevator in which the blades are opened during the discharge stroke 40.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a support frame extending in the vertical direction, and is made of iron plate, angle steel, or the like. The support frame I is provided with one guide wheel 2 at the bottom and two guide wheels 3.4 at the top.

The lower guide wheel 2 has a vertical rotating body part 5 and a cantilevered horizontal rod 6 provided on one side of the vertical rotating body part 5, and is pivoted to the support frame 1 by a bearing 7.

The lower guide wheel 2 is formed by casting or synthetic resin injection molding by silver-gold processing. The vertical rotating body portion 5 is connected to the horizontal rod 6.
Since it is a necessary member to add more parts, it is not limited to the disc shape as shown in Figure 1, as long as the horizontal rod 6 can be attached, and even a structure in which the mounting arms extend in the radial direction, such as an eight-hand shape. The number of horizontal rods 6 is determined depending on the size of the bucket, which will be described later, but 8 rods is preferable. The vertical rotating body portion 5 and the horizontal rod 6 may have an integral structure or a separate structure, and the cross-sectional structure of the horizontal rod 6 may be arbitrary, and may be either a round bar or a square bar like a pencil. The tip of the horizontal rod 6 in the example is shown in a cantilever structure at the free end, but this is because it facilitates the attachment and detachment of the bucket, which will be described later.
It is also possible to connect the tips of the horizontal rods 6 with an annular body. When the annular body is used in this way, the horizontal rod 6 is reinforced, so that the horizontal rod 6 can be formed to be thin.

The upper front guide wheel 3 is mounted on the front side of the upper part of the support frame 1 with a shaft Φ by a bearing 8. Reference numeral 9 denotes a rotating shaft of the upper parallel guide wheel 3, and the single rotating shaft 9 protrudes outward from the bearing 8, and the driven wheel 10 is fixed to the protruding portion. That is, the upper parallel guide wheel 3 is a driving wheel.

Reference numeral 11 indicates a motor provided at the bottom thereof, reference numeral 12 indicates a rotating shaft of motor 0, reference numeral 13 indicates a drive wheel fixed to the rotation shaft member, and reference numeral 14 indicates a belt wound between the driven wheel 10 and the drive wheel B. The upper parallel guide wheel 3 has a vertical rotating body part 15 and a cantilevered horizontal rod 16 provided on one side of the vertical rotating body part 15.

An upper rear guide wheel 4 is fixed to the rear portion of the support frame 1 by a bearing. 17 is a rotating body portion, and 18 is a horizontal rod.

Thus, between the lower guide wheel 2, the upper rear guide wheel 4, and the upper parallel guide wheel 3, an endless bucket continuous body in which buckets 19 are connected one after another is wound. The endless continuum is the horizontal bar 6.
,■, 16 are connected with the buckets 19 facing inward with a gap 21 in between.The bucket endless series 9 of the present invention has the buckets attached to the belt like a normal bucket elevator. Bucket, not structure19
It is a beltless structure formed by connecting two parts one after another.

The bucket 19 has a size of about 10 x 10 x 30 cm, and its internal volume is very large compared to conventional ones, and the grain lifting efficiency per bucket 19 is very high. may be made of metal, but
It is easy to manufacture if each one is made of rubber or synthetic resin.

The buckets 19 are formed independently one by one, and semicircular arc-shaped rear hooks are integrally formed on both left and right sides of the rotating rear side of the rectangular bottom n of the bucket 19. do. The rear hook n, 23 is for connecting the buckets 19 one after another, but also has the purpose of being on the top of the shaft when rotating the buckets 19.

24 is an opening of the rear side tool 2n. Opening 24
The opening 24 is formed facing the gap 21 so that the transverse rod 6.18.16 engages therein.

A semicircular arc-shaped tip hook δ is integrally formed in the center of the rotation destination side of the rectangular bottom η of the bucket 19 to project.

The front hook δ also connects to the horizontal rod 6 in the same way as the rear hook n.
18 and 16 are formed in the opening that engages with this, but the front hook δ is shaped more like a C shape than a semicircular arc compared to the rear hook n.

bucket! When connecting 9, the rear side connection n, 2
3 to fit the shaft rod n, and the front hook b is fitted to the shaft rod n fitted to the backup hooks n and n. At this time, if the cross-sectional shape of the shaft I is a round bar without slits, the horizontal rods 6, 18, 16 cannot be engaged with each other, so the shaft rod n
Also, a slit n is formed in which the horizontal rod 6, 18, 16 can be held. That is, a shaft n having a slit 2B is fitted into the rear flag n, 23, and a front hook 5 is fitted onto the shaft n. In such a configuration, if the slit 2B and the opening 24 are misaligned, the engagement of the horizontal rods 6, 18, 16 will be hindered, so the slit 28 and the opening 24 are It is necessary to prevent the position from shifting. For example, after aligning the slit n with the opening 24, the rear hooks n, 23 and the shaft n are fixed with adhesive. Alternatively, the nut 29 may be tightened from the outer surface of the rear hook n, 23 to fix both. Further, the rear hook n,
A key groove may be formed between 23 and the shaft n, and a key may be inserted and fixed in the key groove.

The above is the fixation of the rear hook B, n and the shaft n,
Since the distal hook 5 is movably attached to the shaft n, it cannot be fixed, and since the distal hook δ has an opening π, it is likely to be in an incompletely fitted state. Secure the retaining area as much as possible as a mold to prevent it from coming off.1
I'm going to buy it.

A right side wall and a left side J31 (Fig. 3) are integrally provided at right angles on both left and right sides of the bottom of the rectangular shape, and a front side wall (the Rear side wall wings are integrally formed on the rear side of the rectangular bottom η in the rotational direction.

The right side wall (9), the left side wall 31, the front side wall [, the rear side wall 33]
Both are the same height, but the bottom is wider.

The upper part should be narrower and an opening should be formed at the upper part of the same height. An opening/closing lid for opening and closing the opening is attached to either the right side wall or the left side wall 31. The opening/closing lid 5 is opened and closed by a solenoid or a spring mechanism.

An abutting rod is attached to the opening/closing lid 5, and an abutment is provided on the moving path of the abutting rod, so that the opening/closing lid 5 is formed to open and close. If a roller is attached to the tip of the abutment rod, the action will be smooth. The abutting bodies g have a structure that allows them to be moved in and out, and are provided in a plurality at positions where the opening/closing lid is desired to be opened and closed, and are moved in and out by remote control to open and close.

Therefore, the endless continuum forms a feed section blade at the point where the lower guide wheel 2 turns, and the lower guide wheel 2 → the upper rear guide wheel 4 travels upward (as the upper crosspiece guide wheel 4 → the upper front guide wheel). The guide wheel 3 becomes the ejection stroke hammer, and the upper forward movement of the own vehicle 3 → the lower guide wheel 2 becomes the downward stroke 41.

The opening/closing lid of the bucket 19 has two parts: 1. Open when moving the supply section (1) and close during the upward stroke (and downward stroke 41);
Ideally, it should be opened during the ejection stroke 40. The example diagram shows a state in which the upward stroke chisel is closed and the other chisels are open. If the opening/closing lid 19 is left open and is formed so that it can change direction at each corner, it will partially overlap like a lens shutter.

The space surrounded by the bottom η, the right side v30, the left side wall 31, the front wall sludge, and the rear wall n becomes the internal volume of the bucket 19, and the internal volume includes, as described above, Comparatively, it is several times larger.

Figures 4 to 7 are examples of applications of the rice milling device for circulating milling.

A rice polishing device C and a rice filling tank 4 are located near the endless continuum.
3 and a product receiving tank 44, and the discharge gutter 45 of the filling tank 43 is connected to the endless continuous supply section (bucket 19 for transferring the product).
The opening 34 is opened.

When the bucket 19 approaches the upper part of the hopper 46 of the rice polishing device C of the discharge stroke mallet of the endless continuous body 4, the opening part is opened and dropped, the rice is polished by the rice polishing device 42, and the rice is discharged from the rice polishing device 142. The gutter 47 is opened to the first part of the bucket N9 of the endless continuum n that transitions between the supply parts.Then, the filling tank 43 → the discharge gutter 45 is endless?

(effect) Next, we will discuss the effect.

(Description of Bucket Elevator) The buckets 19 of the present invention are manufactured one by one by casting, synthetic resin injection molding, silver and gold, etc., and the rear hooks n and 23 provided on the rear side of the bottom n are attached to shafts. Fit the rod n, and fix both with the opening 24 of the rear hook B and the slit 28 of the shaft rod n aligned, and attach the rotation destination side of the bottom n of the next bucket 19 to the shaft n. An endless continuous body is formed by abutting the open chamber of the tip hook δ and pushing it firmly to fit the tip hook δ to the outer periphery of the shaft rod n, and attaching it to the lower part pivoted on the support frame 1. Turn the hooks on the guide wheel 2, upper rear guide wheel 4, and F curve guide wheel 3.

In this state, when the motor 11 is energized to rotate the rotary shaft member, the upper front guide vehicle 3 is driven and rotated via the driving wheel 13 (rotating bell) 14 driving wheel 10-4 rotating shaft 9. The endless continuum rotates through the feeding section (ascending stroke), the discharging stroke (8141), and the descending stroke (8141).When moving the feeding section (grain is fed to each bucket 19, and when moving up the 18th stroke machine) When the abutment rod of the bucket 19 abuts the abutment body provided on the moving path and the opening/closing lid is closed and raised by the elasticity of the spring and moves the sum of the discharge stroke, the bucket 19 is moved along the moving path in the same way. The opening/closing lid is opened against the elasticity of the spring by hitting the abutting body provided at another location of the brush, and the brush 2 is opened.
It is dropped from the opening at No. 9.

The opening/closing mechanism of the opening/closing lid may be either electrical opening/closing or mechanical opening/closing.

Among the above configurations, the fact that - buckets 19 have a supply section, an upward stroke, a discharge stroke 40, and a descending stroke 41 is a novel point that has not existed in the past. After harvesting the grain, it is easy to move it horizontally.

Operation of the rice milling device The brown rice that has been put into the filling tank 43 is supplied from its discharge gutter 45 into the bucket 19 that moves the supply section. is closed when ascending the ascending stroke device, and is placed in the upper part of the hopper 46 of the milled rice VT242 during the discharge stroke of the endless continuum.
When bucket 19 approaches, the opening part opens and falls.
The rice is polished in the rice milling device C and returned to the supply section (by the discharge gutter 47 of the rice milling device 42) to the opening part of the bucket 19 of the endless continuum redundant. Supply section 38: Discharge stroke 4Q of endless continuum
-e Hopper 46 of rice polishing device T42 → Discharge gutter 47 of rice polishing device 42 Supply section (discharge stroke of endless continuous body) Hopper 6 of rice polishing device C After the rice is circulated 3 to 4 times, rice polishing is completed and the rice is taken out to the product receiving tank U.

(Effects) All known bucket elevators, not only the above-mentioned known example, use a belt and have a structure in which a bucket is attached to the belt. That is, it has a structure in which an endless bell (E) is hung between a lower guide wheel B and an upper guide wheel C provided above and below, and buckets D are attached to the endless bell (H) at regular intervals. However, when attaching the bucket D to the endless belt (H), a bolt is integrally provided on the back side of the bucket D, a reinforcing plate is attached between the bucket D and the endless belt E, and the bolt is connected to the reinforcing plate. The bolt is passed through the belt and protruded to the opposite side, and a presser fitting and washer are fitted to the protruding part of the bolt, and the bolt is tightened and fixed with a nut.
The installation work was extremely troublesome. Furthermore, the known bucket elevator has a structure in which the grain is lifted to a predetermined position such as upward or diagonally upward, and when the grain is to be transported laterally after being lifted, a separate loading lift is used. There was an issue of requiring a g-conveyor guard. In addition, since the known bucket elevator has a structure in which a fixed amount of stored grain is scooped up by a bucket and then fried, the bucket cannot be made very large. -Efficiency of frying was low. Therefore, in order to speed up the rotation and ensure efficiency, the discharge conditions are made to be close to the home conditions, resulting in damage to the grain. Not only that, but the surface of the grain is very hard, so especially in the case of unhulled rice, the receiving trough itself that catches the thrown unhulled rice is subject to severe wear, creating the problem of raising the grain while making a lot of noise. . Also, the bucket passes through the accumulated grain layer,
Since the grain is scooped up to its fullest and then raised, it is always overflowing and spilling as it rises.In order to create a structure in which this spilled grain is collected at the bottom without scattering and then scooped up again, the support frame cylinder shown in Figure 1 is used. Requires A. This support frame i'1lJA
Regardless of whether they are made of metal or wood, they are surprisingly expensive and account for most of the cost of a bucket elevator, making the bucket elevator expensive. Since the method involves the bucket passing through the accumulated grain layer and scooping it up, the grain is damaged at that time, and the grain below the line where the bucket passes through is not scooped out. From this, there will always be leftover grain. The remaining grains are not necessarily metabolized and often remain forever, so when a bucket elevator is attached to the dryer for circulation drying, the grains are not dried at all.

There is a problem with uneven drying.

However, one aspect of the present invention is a bucket endless continuous redundant structure in which buckets with lids 19 are connected one after another between the lower guide wheel 2, the L front and rear guide wheels 4, and the Ichigoribu Tominai wheel 3, which are mounted on a support frame L. The endless continuum π winds the part that turns the lower guide wheel 2 (into the supply section).

The period from the lower guide car 2 to the upper rear guide car 4 is the upward stroke (
The period from the upper rear guide car number to the upper front guide vehicle 3 is defined as the discharge stroke, and the period from the -E group guide vehicle 3 to the lower guide vehicle 2 is defined as the downward stroke 41, and the bucket 19 with a lid is Because the supply section (and the beltless bucket elevator that opens during the discharge process) is used, a. Since the bucket 19 does not use an endless belt.

Easy to manufacture and low cost.

Since the grain is transported horizontally after being fried, there is no need for a spiral conveyor for horizontal transport.

C. Grain lifting efficiency per bucket is high.

2. Since the discharge is not thrown, there is no crop damage.

E. Since there is no discharge, there is no mechanical damage.

-Do not generate large noise.

, no support frame cylinder is required.

H, there is no residue.

When the lower guide wheel 2 is turned, the lidded bucket 19 rotates with the front and back in close contact with each other, so that it is easy to feed grains.

At the beginning of the discharge process, there is a time lag in the opening of the necked brush 2 19, so the rice can be freely taken out to the hopper of the rice milling machine or to the product tank, which widens the range of uses.
