Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly deals with organic wastes such as livestock excrement by stirring to compost, and particularly, on an open type stirring treatment tank, the treatment in the stirring treatment tank is performed. The present invention relates to an organic waste agitation treatment device that prevents agitation travel of an agitation travel machine that runs while agitating objects from running or stagnation and enables safe use.

[0002]

2. Description of the Related Art Conventionally, for treating manure and excrement of livestock by agitation and composting, for example, an agitation treatment tank having a flat and long rectangular shape having a considerable width and depth. Is excavated and formed on the ground surface, for example, and the organic waste, which is the object to be treated, is added to this stirring treatment tank,
The stirring traveling machine is reciprocated between the input side end and the unloading side end, and the stirring rod with stirring blades provided on this stirring traveling machine is rotated in a rotary direction along the traveling direction, thereby stirring processing tank. The object to be treated is stirred.

In the case of such an open linear rotary type, from the viewpoint of economic efficiency, the object to be processed is agitated when traveling from the end of the carry-out side to the end of the input side to be processed. It also serves as a unloading movement to the unloading side, and when returning from the opposite loading side end to the unloading side end, the stirring rod is pushed into the workpiece while the stirring rod is pushed into the workpiece to displace the workpiece. It is returning to running.

That is, as shown in FIG. 8 (A), driven and guided by traveling rails 103 arranged on both side edges of the agitation processing tank 101 in which the material to be processed P such as organic waste is charged and stored. The traveling wheels 123 are
The stirring traveling machine 110, which is configured to travel before and after 1, that is, on the unloading side, that is, the stone loading side, is arranged on the stirring treatment tank 101. When the stirring traveling machine 110 travels, the workpiece P is stirred by rotating a stirring rod 134 with a rotary stirring blade provided in the stirring traveling machine 110 along the traveling direction thereof. The drying process is performed so that the predetermined moisture content is obtained, and the workpiece P is moved from the loading side end to the unloading side end with the rotation of the stirring rod 134 in a plurality of reciprocating travelings on the stirring processing tank 101. It is also designed to be a one-way transport in which it is carried out sequentially. Therefore, as described above, when traveling from the unloading side end to the loading side end,
It is assumed that the stirring rod 134 is rotated toward the end side on the unloading side, and the stirring rod 134 is not rotated during the returning traveling in the opposite direction and is kept submerged in the object P to be processed.

[0005]

However, in such an open linear rotary type stirring traveling machine 110, when the stirring traveling from the carry-out side end to the charging end side, the workpiece P has a large degree of drying and becomes hard. A lot of straw, rice husks, sawdust and other auxiliary materials,
The foreign matter such as stones and wood chips is mixed in, or the stirring rod 134 is difficult to enter the object to be processed P due to other reasons. The stirring rod 134 does not enter the object to be processed P. There is. Then, as shown in FIG. 8 (B), the end of the stirring rod 134 hits the object P to be processed, whereby the stirring traveling machine 11
0 itself is floated on the object to be processed P, and the stirring rod 134 is rotated on the object to be processed P.
In some cases, the agitation traveling machine 110 may run undesirably when the agitation processing tank 101 is run, and the object P to be processed is not agitated during the travel. Then, a large loss such as an overrun from the end of the agitation processing tank 101, a damage to the processing tank shop, a personal injury when a worker is present, a serious accident, or the like occurs.

On the contrary, when returning from the input side end to the carry-out end side without agitation, the agitation rod 134 is supposed to travel while being pierced into the object P to be processed. Then, the stirring rod 13 caused by the above-described object P that causes the runaway
The entry inhibiting factor of No. 4 becomes resistance when traveling, and may cause the stirring traveling machine 134 itself to slip (slip) without traveling. As a result, as long as no overload current flows through the traveling motor, the traveling motor is rotating, and thus the traveling wheel 123 continues to idle, and the traveling wheel 123 itself is scraped with the passage of time. Rail 103
There is a case that it also cuts. Then, replacement of the scraped traveling rail 103 and traveling wheels 123 requires a great deal of labor and cost.

Therefore, the present invention was created in view of the above-mentioned various existing circumstances.
The safety is ensured by always detecting the traveling speed in any of the returning traveling, and if it becomes abnormally faster than the traveling speed set as a normal one, it is regarded as a runaway and is made an emergency stop. In addition, if it becomes abnormally late, it tries to escape from the stagnation position as if it is stagnant, and when it is impossible to escape, it is possible to avoid equipment damage, etc. By constantly monitoring the distance from the traveling rail, when the agitating traveling machine is detected as floating or derailed, an emergency stop is made to prevent runaway and safety of the organic waste is agitated. An object is to provide a processing device.

Is reinforced by a reinforcing member 38, and a tip is provided with a stirring blade 39 formed of a plate material that is wide in the stirring direction. The stirring rods 34 are arranged at predetermined intervals with respect to the stirring shaft 33, and the object P to be treated in the stirring treatment tank 1 is
In order to prevent the stirring portion from being biased in the width direction and to stir evenly in sequence as the vehicle travels and rotates, for example, the adjacent ones can be changed in angle in the projecting direction sequentially, 1. As shown in FIG. 2, they are arranged radially when viewed from the side, and are arranged at equal intervals when viewed from the front and rear as shown in FIG. By doing so, consideration is given so that the stirring resistance caused by the stirring rod 34 that enters the object to be processed P is not biased even partially with respect to the stirring shaft 33.

The control mechanism 41 is incorporated and installed in a control box 42 arranged on the front side of the stirrer main body 11 of the stirrer traveling machine 10, for example. (Operation time), selection of these automatic or manual operations, selection of necessity of stirring when traveling to the carry-out side or the input side, and the like can be controlled. In addition, this control mechanism 41
In addition, the agitator body 1 may be disturbed during traveling due to obstacles, such as during agitation of the object P to be treated or during a return traveling without agitation.
Derailment detection means 43 for stopping the traveling of the stirring traveling machine 10 by detecting that 1 has separated from the traveling rail 3 and floated up, and when it is detected that the stirring machine main body 11 has also stagnated (stopped), the escape operation After the trial, when the escape is impossible, the stagnant / runaway detecting means 44 for stopping the traveling of the stirring traveling machine 10 is provided. The derailment detection means 43, the stagnation / runaway detection means 44, etc. may be provided with at least one of them, and an abnormal state at the time of stirring traveling is detected, and an appropriate treatment is executed.

The control box 42 is formed in the shape of a box having left and right doors whose front and rear surfaces are opened and closed in a double-door manner, for example, and various operation buttons for control are arranged on the front surface of the door (see FIG. 3).

The derailment detecting means 43 is associated with the side frame 12 of the stirrer body 11 and is connected to the traveling rail 3
It is for a proximity sensor that is arranged downward on the side. The proximity sensor constantly detects the vertical distance from the traveling rail 3 surface, and when the vertical distance exceeds a certain value, it is recognized that the agitator body 11 is in a state of being lifted from the traveling rail 3 and that If the correction is not made within a preset time, for example, the traveling mechanism 21
The power supply to the traveling drive source 22 is cut off to make an emergency stop. Further, the derailment detection means 43 is arranged at a position symmetrical with respect to the stirrer main body 11 by being arranged at the front and rear ends of the stirrer main body 11 at one of the left and right in the front part and at the other of the left and right at the rear part. It is as being done.

The stagnation / runaway detecting means 44 is used for the traveling rail 3
The speed at which the agitation traveling machine 10 travels above is detected, and when it is detected to be above a certain speed, an emergency stop signal is transmitted to stop traveling to the traveling mechanism 21,
Alternatively, by detecting that the speed is below a certain speed, the stirring mechanism 31 is instructed to perform stirring for the escape operation from the stagnant position and stop traveling of the traveling mechanism 21 when the escape is impossible. For the speed detection for that purpose, the number of the proximity sensors 45 attached to, for example, the side pedestal frame 12 in the stirrer main body 11 detecting a plurality of speed detection plates 46 arranged on the traveling rail 3 at regular intervals within a predetermined time. It is due to. It should be noted that runaway detection monitoring is performed during stirring traveling by traveling from the unloading end side to the loading end side, and stagnation detection monitoring is performed during non-stirring traveling by traveling from the loading end side to the unloading end side, respectively. It is monitored by the control circuit and has a different circuit configuration in the control circuit.

When stagnation is detected when traveling without stirring from the loading side to the unloading side, the stirring traveling machine 1
With respect to the traveling drive source 22 in the traveling mechanism 21 of 0,
Since the overload state and the overcurrent state result in thermal action and complete stoppage, the traveling wheels 23, conversely, are in a slip state because the load is reduced, and they remain rotating on the spot. Because of it, it remains stuck at that position.

The speed detecting plates 46 are arranged, for example, by being fixed by welding, for example, at predetermined intervals so as to straddle the open surface of the open part on the outer side of the traveling rail 3, and the proximity sensor 45 serves as the speed detecting plate. It is supported from the side pedestal frame 12 through an appropriate supporting member so as to be directed to 46 (see FIGS. 5 and 6). Speed detection plate 4
6 itself is arranged at substantially the central portion of the channel steel material forming the traveling rail 3 and each connection portion between the channel steel materials as in the illustrated example, and particularly the speed detection plate 46 disposed at the connection portion.
Is welded only to the open surface of any one of the adjacent channel steels, and is positioned so as to close the open surface on the other open surface. Are fixed by welding to both side edges of the open surface of the channel steel. By doing so, it is possible to secure the load resistance against the load applied to the traveling rail 3 made of the channel steel, the expansion / contraction allowance, and the like. The proximity sensor 45 detects only the speed detecting plate 46, and does not detect, for example, the raw material of the channel steel, the rail joint 5, or the like.

The speed detecting plates 46 are arranged at the same intervals so that the front and rear speed detecting plates 4 are arranged at the same intervals.
The traveling speed of the stirring traveling machine 10 is detected by the passage time in 6, and the passage time at which safety can be secured can be set depending on, for example, differences in the surrounding conditions, characteristics, and habits at the installation location. Moreover, when the speed is detected by the power supply frequency, the set time can be adjusted according to the power supply frequency.
Even with respect to the above, it is possible to ensure the operation of the stagnation / runaway detection means 44 by the arrangement arrangement of the speed detection plate 46 which ensures safety.

Further, when the derailment detecting means 43, the stagnation / runaway detecting means 44, etc. have eliminated the trouble such as the emergency stop due to the detection of the abnormality, these are reset,
The agitation run can be performed again.

An example of use in the embodiment configured as described above will be described together with the control instruction at the time of abnormality detection during operation shown in FIG. The livestock excrement or the like, which is the object to be treated P, is directly charged into the stirring treatment tank 1 as it is or together with various auxiliary materials for moisture adjustment, sequentially from the charging side end, and the charging storage range, the stirring range range, etc. are supported. The positioning stoppers 28 are set on the traveling rails 3 on the loading side and the unloading side respectively. On the other hand, when the stirring traveling machine 10 is operated, the control mechanism 41 sets the operation mode in advance and starts the operation. For example, manual operation or automatic operation, selection of stop, selection of necessity of stirring when traveling from the unloading side to the loading side or vice versa from the loading side to the unloading side, and in both directions, floating / derailing, runaway The instruction of the emergency stop control based on the detection of is set by operating various switches.

When the stirring mechanism 31 starts stirring, the traveling mechanism 21 travels from the unloading side toward the loading side while stirring, and the object P to be processed is sequentially transferred to the unloading side by the running. When it reaches a predetermined position, on the contrary, it returns to the carry-out side while stirring without stirring, and this is repeated a suitable number of times to repeat the above operation in the carry-out pit formed at the carry-out side end of the stirring processing tank 1. Treated product P
Carry out.

During such stirring work (step 1: S1)
When the stirring traveling machine 10 is traveling from the carry-out end side toward the loading side end, the derailment detection means 43 determines whether or not the stirrer main body 11 itself is lifted (step 1
1: S11), the traveling speed of the agitator main body 11 is monitored by the stagnation / runaway detection means 44 (step 2: S2).
That is, the stirrer / runaway detection means 44 causes the stirring traveling machine 1 to operate.
The traveling speed of 0 itself is constantly monitored, and when the traveling speed is within a certain range, the stirring traveling machine 10 itself is not lifted by the derailment detection means 43, and the stirring rod 34 of the stirring mechanism 31 causes the object P to be processed. If it enters the inside and is stirring, let it run as it is. When the vehicle reaches a predetermined traveling position on the unloading side (step 14: S14), it depends on whether or not the operation for the designated time is completed (step 15: S1).
5) If it is not completed, reverse running from the loading side to the unloading side. When the stirring operation is stopped and the stirring rod 34 is left in the processing object P during this reverse traveling, the stagnation / runaway detection means 44 monitors whether or not there is stagnation in each section (step 21: S21. ) The object P to be processed is reversely run to a predetermined position on the unloading side, then reversely run, and the like, and the operation is repeated within a designated time, and the process is completed (step 16: S16).

When the stirring traveling machine 10 travels from the unloading side to the charging side while stirring, it is confirmed that the stagnation / runaway detecting means 44 travels within a predetermined section in a shorter time than a predetermined time required for the traveling. If detected (step 2: S2), it is detected that the vehicle is running out of control (step 3:
S3) An emergency stop signal is transmitted to the traveling mechanism 21 to stop it (step 4: S4). Further, the derailment detection means 43 causes the stirrer main body 11 to be separated from the traveling rail 3 at a predetermined interval, and thus becomes a floating state (step 12:
S12), if it is not corrected within a predetermined set time (step 13: S13), it is detected that the vehicle is running in a floating state, and an emergency stop is similarly performed to prevent runaway. Yes (step 4: S4).

On the contrary, when the stirring traveling machine 10 stops its stirring operation and travels from the loading side to the unloading side, the stirring rod 34
When the vehicle is traveling with the inside of the object P to be processed, the presence or absence of stagnation in each section is monitored (step 21: S2
1) Similarly, when the stagnation / runaway detection means 44 detects that the travel time is longer than the fixed time required for the travel within a predetermined section or that the travel is not running, it is detected as stagnation (step 22: S22) The escape operation from the stagnant position is tried a suitable number of times. That is, the stirring mechanism 31 that has been stopped is operated to forcibly and auxiliaryly rotate the stirring rod 34 within a predetermined time, and if necessary, rotate in the forward and reverse directions to stir the object P around the stirring rod 34. By doing so (step 23: S23), the stirring rod 34 can be moved while entering the object P (step 24: S24). After that, if the traveling operation is restarted, the predetermined set operation is continued (step 26: S2).
6). At this time, if the escape operation is not restarted after a predetermined number of times, for example, three attempts of the escape operation, an emergency stop signal is transmitted to the traveling mechanism 21 to stop (step 25: S25). When the escape / running is started and reaches a predetermined position on the loading side, if it is within a preset running operation time, the vehicle reversely travels at the unloading side position and moves toward the loading side while stirring and transferring the object P to be processed. The operation is completed within the specified time by repeating the operation within the specified time by running the vehicle (step 27: S27), and when the completion is confirmed, the operation ends (step 2).

EFFECTS OF THE INVENTION Since the present invention is configured as described above, in the stirring traveling machine 10 that travels back and forth on the stirring processing tank 1 having an open upper structure to stir and carry out the object P to be processed,
The stirring traveling machine 10 constantly detects the traveling speed in both the stirring traveling to the input side and the returning traveling to the unloading side, so that the traveling speed becomes abnormally faster than the traveling speed set as a normal one. In case of emergency, safety can be secured by making an emergency stop as if it is running out of control, and if it is abnormally slow, it is considered to be stagnant and an appropriate number of escape operations are tried to remove it from the stagnant position. When it is possible to escape, the vehicle is normally run, and when it is not possible to escape, it is stopped to prevent damage to the equipment. Further, by constantly monitoring the interval between the stirring traveling machine 10 and the traveling rail 3 on the stirring processing tank 1,
When floating of the stirring traveling machine 10 is detected, it is possible to make an emergency stop for safety in order to prevent runaway and improve safety.

That is, in the present invention, the object P is agitated by reciprocating the agitating machine 10 on the agitating tank 1 having an open upper structure for charging and storing the object P such as organic waste. When carrying out the stirring process, the stirring traveling machine 10
Is equipped with a control mechanism 41. The control mechanism 41 detects that the agitation traveling machine 10 is stagnant when the traveling speed is slower than an allowable constant range, and detects that the agitation traveling machine 10 escapes. Stagnation / runaway detection means 44 for stopping the traveling when it is impossible to escape after the trial, or for stopping the traveling of the stirring traveling machine 10 by detecting that the traveling is out of control when the traveling speed is faster than a certain range. This is because the machine 10 itself has at least one of the derailment detecting means 43 that floats above the agitation processing tank 1 and detects that it is above a predetermined vertical interval and stops the traveling of the agitation traveling machine 10, As a result, it is possible to prevent floating of the stirring traveling machine 10 during traveling and a runaway state associated therewith, and to prevent seizure of the traveling drive source 22 during stagnation, wear loss of the traveling wheels 23, and the traveling rail 3 respectively. Etc. can be greatly improved the safety of such can prevent.

The derailment detecting means 43 of the control mechanism 41 is
A proximity sensor associated with the stirrer body 11 is arranged toward the traveling rail 3 side, which is the traveling surface on the agitation processing tank 1, and the proximity sensor constantly keeps the vertical distance from the traveling rail 3 surface. It is detected that the agitator main body 11 is lifted from the traveling rail 3 when the vertical interval becomes a certain value or more.
Since the stirring rod 34 of the stirring mechanism 31 does not enter the inside, it is possible to detect the floating of the stirring traveling machine 10 itself that is traveling on the object P to be processed. Moreover, when the floating state is corrected within a preset time, for example, when the stirring rod 34 re-enters the object P to be processed during traveling and traveling and stirring are not started, traveling of the stirring traveling machine 10 is performed. Because it is stopped, if there is a return to normal running that does not lead to a runaway, you can continue running as it is, and conversely you can avoid a runaway that is in a dangerous state.

On the other hand, the stagnation / runaway detecting means 44 of the control mechanism 41 is a proximity sensor 45 attached to the agitator body 11.
However, it is assumed that the traveling speed is detected by the number of the plurality of speed detecting plates 46 arranged on the traveling rail 3 at regular intervals within a certain period of time, and by detecting that the traveling speed is equal to or more than the certain speed. Since the traveling of the stirring traveling machine 10 is stopped or is stopped after the trial of the escape operation of the stirring traveling machine 10 is detected by detecting that the traveling speed is lower than a certain speed, for example, the stirring rod 34 in the stirring mechanism 31 is used. If the stirring traveling machine 10 stops running due to its resistance or the like while the vehicle travels while it is still entering the object P, it is assumed that the stirring traveling machine 10 is in a stagnant state at that position for a certain time or more. 10 can be stopped. Further, even when the stirring rod 34 rotates in such a manner as to run on the object to be processed P without entering the object to be processed P, stirring is performed so as to detect this and stop the runaway. The traveling of the traveling machine 10 can be stopped.

Further, when the stirring traveling machine 10 is in a stagnant state, prior to the control of stopping the traveling mechanism 21 due to the stagnant state, the escape operation by stirring the stirring rod 34 in the stirring mechanism 31 at the stagnant position is tried a suitable number of times. Therefore, when the vehicle escapes by the trial, the traveling operation can be continued as it is, the control can be performed without waste in time, and it can be useful for the automatic driving.

The stagnation / runaway detection means 4 of the control mechanism 41
The speed detection plates 46 in No. 4 are arranged at predetermined intervals on the open surface of the traveling rail 3 having a groove shape in the cross section whose outer side is open, and are arranged to abut at the connection portion of the traveling rail 3. Steel members that are connected to each other at a specified gap in correspondence with the expansion and contraction action of the steel material that expands and contracts in winter, summer, etc. Even if they expand or contract with each other, they are not affected by deformation, etc., and the detection action of the proximity sensor 45 is not hindered, and a stable detection operation is always guaranteed. In addition, it does not hinder the expansion and contraction of the steel material itself, and also the stirring traveling machine 1 for the rail-shaped member having the groove shape.
It is useful for supporting a load of 0, and contributes to the running stability of the stirring traveling machine 10 further by not distorting.
