Description

[Detailed Description of the Invention] Inventively, the process of digging up root vegetables such as beets and transferring the spheres to an annular elevator and loading them into packets from the final conveyor (in this process, the rotation speed of the annular elevator rotor is inhibited). This invention relates to a rotation starting device for an annular elevator that forcibly rotates the spheres so that they can flow from an excavation conveyor to an annular elevator without stagnation even under such conditions.

In the annular lifting rotating body of a conventionally known annular elevator, if a foreign object or a sphere gets caught between the annular lifting rotating body and the guide plate and obstructs the rotation, the rotation may stop, or a box or ice may form. In such seasons, beet leaves, etc. freeze or ice builds up on the starting engagement part, which not only prevents rotation, but also causes the annular elevating rotating body to deviate from the starting wheel's orbit and fall off. there were.

That is, conventionally, the starting configuration for an annular lifting rotary body is to start at three or four points on the outer periphery of the circumferential orbit, and to rotate while supporting the circumferential orbit with one or two guide wheels, which prevents rotation. When this resistance is applied, the circularity of the circumferential orbit is damaged, and the entire body is overflowed by the spheres sent from the conveyor to the activation teeth, and the spheres are trapped in the surrounding space. Until its function is restored, time and effort are wasted, and the waste is astronomical.

The present invention has been invented to eliminate the above-mentioned conventional drawbacks, and the object of the present application is to closely rotate a guide wheel inside the circumferential orbit of an annular elevating rotating body rotated by a starting wheel. An annular valve that prevents the annular lifting rotor from separating from the starting wheel. To provide a rotation starting device for the machine.

Another object of the present application is to arrange two starting wheels spaced apart from each other for a certain period of time on the outside of the circumferential orbit of an annular elevating rotating body rotated by the starting wheel, and to dispose two starting wheels on the inside of the circumferential orbit. To provide a rotation starting device for an annular elevator, which prevents an annular elevating rotating body from detaching from a starting wheel by closely rotating a guide wheel to a position between the two wheels.

Another object of the present application is to attach an elastic member to the guide wheel so as to apply a force to move it toward the circumferential track.
To provide a rotation starting device for an annular elevator, which increases the frictional force or pressing force of the circumferential track in contact with the starting wheel so that the circumferential track and the starting wheel can rotate without slipping.

A further object of the present application is to fix small diameter pulleys to the respective shafts of the guide wheel and the starting wheel, and to tension both pulleys with an endless coil spring, so that the guiding wheel and the starting wheel have elasticity. To provide a rotation starting device for an annular elevator in which a starting wheel and a circumferential track can actually rotate without slipping by attracting each other.

Another object of the present application is to attach the shaft of the guide wheel to one end of the lever, and attach the lever to the frame as appropriate.
At the same time as pressing the spring on the other end of the lever]
By adjusting the length force of the spring, it is possible to press the wheel to the circumferential orbit, prevent the wheel from separating from the circular orbit, and ensure the rotation of the starting wheel. 1
(We are currently working on providing a rotation starting device for an annular elevator that rotates an annular elevator rotating body by transmitting information.

Furthermore, another object of the present application is to rotate the two driving wheels with eleven main driving wheels.
Out of 191KN of q, the starting wheel of one country always rotates i% tangent to the circumferential orbit to ensure the annular lifting and lowering rotating body ((Rotating start of annular elevator designed to rotate!:・Power equipment:,'l ,', ;7 is to be provided.

(Another purpose of 1 is to form the circumferential track with a channel material with a cross section of ■ shape, and to fit the starting wheel inside the rising edge of the channel material. To provide a rotation starting device for an annular elevator which prevents sideways slippage.

The present invention forms a circular circumferential orbit in the annular lifting rotating body with the open end of the channel material (U-shaped) facing outward, so that the raceway ring is difficult to come off in the lateral direction. is engraved, and the driving wheel is also formed with a tooth profile similar to the tooth profile,
Both tooth profiles are engaged to increase the coefficient of friction, and a guide wheel is provided on the back (inside) of the circumferential raceway, in other words, as a counter force, and the circumferential raceway is sandwiched between the starting wheel and the guide wheel, and this is removed as a single unit. This is a rotation starting device for annular elevators for prevention and slip prevention.

Furthermore, the present invention has a tension spring attached to the guide wheel, so that when a foreign object is caught between the engagement of the starting wheel, the guide wheel is pushed and the tension spring prevents the foreign object from passing. The annular elevator should be able to return to normal without stopping, and should stop even if it encounters a condition that completely prevents rotation. The device jt is a device that can produce sufficient effects.

In addition, in conventional annular elevators, the rotational torque between the circumferential orbit and the starting wheel is large (the more it is applied, the more the circular I will lose its shape, and the more the circularity is lost, the more the circumferential orbit will move away from the starting wheel. This is the cause of more slip than necessary and is a major hindrance to the efficiency of excavation work, and the coefficient of friction decreases with age and the slip becomes more severe. It is.

This structure was openly used to prevent foreign objects from getting caught and being damaged by forced rotation.

In the present invention, there is usually no slippage, but even a small amount of frozen soil adhesion, a foreign object that does not cause damage, or even a pinched bulb body that does not cause damage, etc. It is possible to automatically avoid serious damage to the annular lifting rotating body by causing the first slip as a safety valve only when it is applied to the starting part, and when the friction coefficient becomes insufficient due to aging or This invention relates to a torque limit adjustment device for a meshing part that makes it possible to adjust the torque limit according to areas where there are few conditions that cause damage due to boulders, etc.

Furthermore, the present invention forms tooth-shaped portions of the same pitch on the inside of the circumferential orbit (rotating body guide) and on the outer periphery of the driving wheel so that the driving wheel and the circumferential orbit mesh with each other, and isolate the driving wheel for a certain period of time. The installation is such that a circumferential raceway is placed on both raceway rings, and a guide wheel is pivotally installed so as to sandwich the circumferential raceway between the two raceways or opposite the two raceways, The guide wheel is provided so as to be rotatable closely on the circumferential track, or the guide ring is tightly pressed against the circumferential track side using an elastic member, or the guide wheel is set in several stages with the tension of a lever set. By making it possible to set it in the proper position, etc., the breakage range (limit point) as mentioned above can be avoided! Since the 1lj7 position can be adjusted so that slip occurs only at 1'f+'/C as a safety valve, the annular lifting and lowering rotating body will not fall off due to the circular structure (
However, the rhythm of the conveyor transfer, lifting and lowering Niscalate, and tank loading while taking this %j16;
#lj': :((De・Tatsumi＞=、H Even in old age, the stamina can be improved by adjusting it'Js,'qzuttotsu and other products have effects and effects that cannot be expected.) In addition to the rotary starting device of the three-state elevator, the present invention also provides a starting device for two parts thrown close together,
・In the middle of fortune telling (τ twin occurrence! 1 power) Convey the startup that envelops the oil from the theory to the 2nd part, make the outer friction surface of the 1 reactor theory larger, and make this as a whole. Furthermore, a guide wheel is installed in a position opposite to the starting wheel, sandwiching the circumferential IwL path. As it spreads due to foreign matter (4), the main starting axis is used as a fulcrum and the other side's axis (4) comes into close contact with the circumference, working to further prevent slipping.

Furthermore, depending on the size of the foreign object, the tension spring (elastic member) can automatically adjust the pressing force that presses the guide wheel against the circumferential orbit, thereby avoiding damage caused by meshing and forcing rotation without slipping. This enables a continuous rotation starting device for the annular elevator.

Now, to explain an embodiment to achieve the above object, the front and rear surfaces and the outer periphery are surrounded by a lattice-like member (1) formed of metal wire or wire, etc., and the center of the front and rear surfaces is opened in a large circular shape. 2) was formed by a donut-shaped annular elevating rotating body (

In addition, the guide wheel (9) for holding down is rotatable and placed inside the circumferential orbit (5) so that the circumferential +lL path (5) does not separate from the starting wheel (6). In addition to placing them in close proximity, the driving wheel (6) and the circumferential orbit (5) are suppressed by applying a pressing force Z to the circumferential orbit (5j) and the driving wheel (6). The friction coefficient is increased to a large extent to prevent the circumferential orbit (5) and the starting wheel (6) from falling off or slipping.

Next, if we explain the @ guiding wheel (9), circumferential orbit (5), and starting wheel (6) of the present invention according to the figures, in the case of Fig. The starting wheel (6) of the circumferential raceway (5) is fitted into the channel material having a cross-sectional opening shape of the circumferential raceway (5).
