Description

Power transmission actuator of fodder mixing / supplying apparatus

The present invention relates to a drive transmission of a feed mixing feeder for automatically feeding feed to large livestock such as cows, and more particularly, to allow the rotational speed of the rotating screw in the feed mixing feeder to be changed. It is to make efficient mixing according to the kind, condition or input amount of feed material fed into the inside, and by using the rotational force provided from the outside, the hydraulic pump, which is the power source of various actuators used in the feed mixing feeder, is driven together. And the operation of the mixed feed is to be made.

Feedstock for large livestock such as cows is mixed with feed ingredients such as hay with a lot of fiber and processed foods of various ingredients. Feedstocks are relatively long because of the characteristics of rubbing cows. Because it is composed of rice straw, it requires a process of cutting it finely and mixing it with the processed feed again.

For this process, a separate cutter and a mixer are provided together in a conventional barn, and the worker feeds the mixed animal feed by the mixer at regular intervals to feed the livestock.

However, the cutting and mixing process of the general feed as described above is very cumbersome and requires a lot of time and equipment, and the mixed feed also has to feed the livestock as the worker moves one by one. This is quite delayed, so there is an uneconomic problem.

In addition, when the house is a large-scale facility, the problems as described above are further derived, so that the power means of the feed mixer and the utility model registration application in 1999 are similar to the utility model registration application 716 of 1998. A mixer having a direction of forming a rotating screw such as 1318 is devised respectively, and Utility Model Application No. 3691 of 1999 allows for efficient cutting of relatively long rice straw or hay while reducing power consumption. In addition to the uniform mixing of the feed is made possible to move it in the barn by a separate transport, there has been applied for a mobile feed mixer that can feed the feed while moving the mixer.

However, the mobile feed mixer as described above requires a separate transportation means, so the driver must operate it, and the transportation means also cannot be specially manufactured, so the existing farm machinery is used as a transportation means. It is large and consumes a lot of power, and in severe cases, soot is generated in the barn, which may be a cause of harm to livestock health.

In addition, since the feed must be supplied at a certain time, the worker checks the feeding time every hour, and when the feeding time comes, there are many problems in terms of time utilization because the feeder must be operated by feeding the transportation means and the mixed feeder. Since the operating speed and the feeding amount of the worker are not constant at all times, there is no systematic feeding, and it is very difficult to control a certain amount of feed or the amount of feed that can be varied as needed, which requires a highly skilled person. Is there.

Accordingly, the applicant of the present invention, as in Patent Registration No. 10-0355491, installs the iron plate rail in the barn, a normal feed mixing machine which is movable by the stationary motor on the upper part, and stops at both ends of the iron plate rail The jaws are laid separately, and the feed mixer is automatically moved at a predetermined time. The feed is mixed and the feed is made according to the setting of the control unit. By stopping the supply and going to the standby state, the feed mixing feeder by the automatic control that the feed mixing and feeding is made automatically by the control unit at a certain time without the need for a separate means of transport has been devised.

As a means for moving all existing feed mixers as described above, a separate vehicle or its own driving motor is used. For example, by connecting the feed mixer to the driving shaft of the tractor, the rotating screw inside It is to be operated, or to install the drive motor in the feed mixer itself is to move the rotating screw at the same time as the feed mixture feeder from the power of the drive motor.

In addition, a separate gearbox is adopted as a means for transmitting power from the various power means as described above to the rotating screw inside the feed mixer, and the gearbox reduces the high speed power means at a low speed. At the same time, by adjusting the gear ratio to give a high rotational force to the rotating screw, it is to perform a role of evenly rotating mixing the feed material having a high resistance through the rotating screw.

However, such a gearbox has a problem in that it is impossible to change the rotational speed of the rotating screw in the feed mixture feeder because it only serves to reduce and transmit the rotational force of the power means to the rotating screw.

For example, in the state that the rotating screw is operated through the gearbox by using the power of the drive motor, when the type of feed material input into the feed mixing feeder is changed or a difference in the length and form of the feed material occurs or If the feed amount is changed, the rotation speed of the rotating screw should be changed accordingly so that the most suitable and efficient mixing is achieved, but the gearbox itself does not have a shift function. Or, irrespective of the input amount, the fertilizer is mixed and stirred with only the same rotational speed in a batch, thereby causing a problem that the mixing time for the fertilizer is too long as well as uneven mixing.

That is, in the case of rice straw or long grass of the forage fed into the feed mixer, a lot of load is generated in the driving power part of the feed mixer in the process of cutting rice straw or grass, resulting in low service life and excessive consumption. Since it is a waste of power, it is necessary to adjust the rotational speed and the rotational force according to the input state of straw and long grass. Therefore, in the case of cutting and mixing rice straw or long grass, the rotational speed should be increased while reducing the rotational speed of the internal rotating screw. Although the load will be reduced, the cutting speed and rotation speed of the rotating screw should be increased and the cutting speed and mixing of the feed should be made reasonably. Since the gearbox is not operated at all and is operated at a constant rotation speed, the load is mixed but the feed is not effectively performed.

In addition, in the conventional feed mixing feeder, the hydraulic device, which is the driving means of the actuator for opening and closing the feed inlet or the feed outlet, is configured separately from the feed mixing feeder. Has a very troublesome and difficult problem, and even if the hydraulic pump is installed in the feed mixer itself, it is extremely necessary in terms of economical aspects and the convenience of operation and operation because the separate power means for driving the hydraulic pump must be separately installed. There is an inefficient problem.

The present invention is to solve the problems as described above, the input shaft is mounted on the gear box receives the power provided from the outside, and the input shaft is formed to connect the counter shaft and the transmission shaft located inside the gear box, but the shift The high speed gears and the low speed gears coupled to the shaft in an idling state are configured such that the counter shaft and the transmission shaft are powered by the gears which are transversely flowed therebetween, and the counter shaft and the transmission shaft are powered. By constructing a built-in hydraulic pump that receives the operation,

It is possible to control the rotational speed of the rotating screw through the transmission shaft and to simultaneously drive a hydraulic pump that provides hydraulic pressure to the actuators used in the feed mixing feeder by using the above driving power, so that more rational and effective feed mix and feed mixing are possible. It is an object of the present invention to provide a drive transmission of a feed mixing feeder having a feature that enables operation for a feeder.

The present invention for achieving the object as described above, the power transmission input shaft which is one end is projected to the outside while being embedded in the gear box, and the counter shaft is connected to the input shaft and rotated together, the rotation force is connected from the counter shaft A transmission main shaft, a first main gear connected to the transmission shaft and rotated together, and a second main gear rotated through a separate intermediate gear from the transmission shaft,

In the shift shaft, a high speed gear idling from the shift shaft and a low speed gear having a larger diameter than the high speed gear are formed. The high speed gear meshes with the first counter gear of the counter shaft, and the low gear is a second counter gear of the counter shaft. And a separate sleeve coupled between the high speed gear and the low speed gear of the transmission shaft to allow sliding in the axial direction while rotating together with the transmission shaft, wherein the sleeve has a lateral flow from the transmission shaft. Through the selective engagement of the high speed gear and the low speed gear through the variable speed of the rotational shaft is configured to be made.

The present invention, instead of the gearbox of the various feed mixers that have been used in the past can be replaced by the drive shift box of the present invention, so that the existing feed mixer can be used as it is, while the input of feed into the feed mixture feeder It can be adjusted to have the most efficient and ideal mixing ratio by adding or subtracting the speed of the rotating screw according to the type, condition or dosage, and variously operated hydraulically in the feed mixer by driving the hydraulic pump together from the power for operating the rotating screw. It is possible to operate and operate the actuator effectively.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall perspective view of a drive transmission according to the present invention, Figure 2 is an internal perspective view of the gearbox of the drive transmission according to the present invention, Figure 3 is a perspective view of the internal connection of the drive transmission according to the invention, Figure 4 is a bottom perspective view of the inner connection portion of the drive transmission according to the invention, Figure 5 is a side view of the inner connection of the drive transmission according to the invention.

As illustrated, the drive transmission device according to the present invention includes an input shaft 10, a counter shaft 20, a transmission shaft 30, and first main gears 40 on both sides of a gear box 100 formed of a split assembly. The second main gear 60 is built in, and the shift shaft 30 is connected to the counter shaft 20 with a different gear ratio through the sleeve 70 flowing by the actuator 80. The rotation speed of the first main gear 40 and the second main gear 60 can be increased or decreased.

In addition, the input shaft 10 is protruded to the outside of the front of the gear box 100 to receive power from the outside, the main gear 40, 60 is the outer shaft of the gearbox 100 outside the rear It is withdrawn so that it can be combined with the rotating screw and spline in the feed mixer feed shaft. In particular, the gear box 100 is equipped with a separate hydraulic pump 93 so that the hydraulic pump 93 is transmitted from the input shaft 10 to be operated simultaneously with the input shaft 10 feed feeder It is to effectively supply hydraulic pressure to the various types of hydraulic actuator used in the.

Here, the input shaft (11) and the transmission gear 12 are formed in the input shaft 10 in sequence, the counter shaft 20, the input counter gear 21 and the first counter gear 22 and As the second counter gear 23 is formed sequentially, the input counter gear 21 is meshed with the input gear 11 on the input shaft 10 so that the rotation of the input counter 10 is performed. The counter shaft 20 has a structure that can be rotated at the same time.

In addition, the high speed gear 31 having a small diameter and the low speed gear 32 having a large diameter are sequentially rotated on the shift shaft 30 so as to freely rotate from the needle bearing 33 coupled to the shift shaft 30. A spline shaft-type hub 34 is fastened between the high speed gear 31 and the low speed gear 32, and a connecting gear 35 is formed at the rear side of the low speed gear 32. On the opposite side of the high speed gear 31 and the low speed gear 32, the high speed connecting portion 31 'and the low speed connecting portion 32' having the same diameter and cross-sectional uneven shape as the hub 34 are formed. It is formed facing each other.

Accordingly, when the counter shaft 20 is rotated simultaneously due to the rotational power of the input shaft 10, the counter shaft 20 meshes with the high speed gear 31 and the second counter gear 23 meshed with the first counter gear 22. The low gear 32 is started idling from the transmission shaft 30 at the same time. Since the high gear 31 and the low gear 32 are meshed with the counter gear in different sizes, they rotate differently. In this case, a neutral state is achieved in which power is not transmitted to the rotating screw in the feed mixer.

In addition, the sleeve 70 is coupled to the hub 34 as shown in FIGS. 6 and 7 between the high speed gear 31 and the low speed gear 32 as described above. The inner surface of the 70 is formed with a hub groove 71 having a shape matching the cross-sectional concave-convex shape of the hub 34 so that the sleeve 70 can flow in the axial direction from the shift shaft 30 and at the same time the shift shaft ( 30) to have a structure that can be rotated together.

Therefore, when the sleeve 70 flows toward the high speed gear 31 by a forcible force, the hub groove 71 inside the sleeve 70 is engaged with the high speed connecting portion 31 ′ of the high speed gear 31. The rotational force of the high speed gear 31 serves to transmit the high speed to the speed change shaft 30 through the sleeve 70 and the hub 34. In contrast, the sleeve 70 faces the low speed gear 32. When the fluid flows, the hub groove 71 inside the sleeve 70 is engaged with the low speed connecting portion 32 'of the low speed gear 32, and the high speed gear 31 is in an idling state, while the rotational force of the low speed gear 32 The low speed transmission to the transmission shaft 30 through the 70 and the hub (34).

When the rotation about the transmission shaft 30 is made in the form of high speed or low speed, the first main gear 40 and the second main gear on both sides through the connection gear 35 formed at the rear end of the transmission shaft 30. 60 receives a rotational force, wherein the first main gear 40 is directly engaged with the connecting gear 35 to rotate, while the second main gear 60 is connected through a separate intermediate gear 50. As the gear 35 is engaged, the first main gear 40 and the second main gear 60 are rotated together with the transmission shaft 30 and rotated in opposite directions.

The reason why the rotation directions of the first main gear 40 and the second main gear 60 are opposite to each other is different from each other in the rotation direction of the feed mixing rotary screws arranged side by side in the feed mixer feeder. For this purpose, by varying the direction of rotation of the rotating screw is to be mixed in various types of feedstock fed into the feed mixing feeder evenly and effectively.

In addition, the hub (70) of the shift shaft (30) due to the operating force of the separate actuator (80) is a medium for variably transmitting the rotational force of the counter shaft (20) at a high speed or a low speed. From the outer surface of the gear box 100, the actuator 80 is mounted in the transverse direction from the outer side of the gear box 100, the transmission shaft 81 at the end of the output shaft 81 of the actuator 80 To combine, the end of the shifting connection 82 is coupled to the shifting shaft 83 is located inside the gearbox 100, the shifting shaft 83 is a separate fork to be coupled to the sleeve 70 ( 84) is formed by bonding.

In this case, an insertion groove 72 is formed on the outer surface of the sleeve 70, and the lower portion of the fork 84 allows the actuator 80 to be inserted into the insertion groove 72. When the driving shaft 81 is operated to operate, the sleeve 70 flows in the transverse direction while the fork 84 flows through the transmission connecting rod 82 and the transmission shaft 83 according to the operating direction of the output shaft 81. It is to be made.

In particular, since the shifting connection 82 is exposed to the outside of the gearbox 100, the shifting connection 82 is forced to an artificial force of a user or an operator in a state in which there is no driving for a separate actuator 80. The sleeve 70 inside the gearbox 100 is pushed or pulled so that the shift may be made.

In addition, the connection structure for transmitting the rotational power of the input shaft 10 to the hydraulic pump 93 is made on a separate idle shaft 90 located in the gear box 100, as shown in FIG. In a state where the first idle gear 91 and the second idle gear 92 are sequentially formed, the first idle gear 91 is engaged with the transmission gear 12 of the input shaft 10 and the second idle gear As the 92 is engaged with the pump input gear 94 of the hydraulic pump 93 fixed on the gearbox 100, the rotational movement force of the input shaft 10 is the hydraulic pump 93 through the idle shaft 90. Since it is transmitted to) will be able to use the high pressure fluid from the hydraulic pump 93 at the same time as the rotation of the input shaft (10).

Such a hydraulic pump 93 is to enable to operate the feed inlet or feed discharge or discharge conveyor used in the feed mixer feed hydraulically, since the hydraulic pump 93 is mounted on one side of the feed mixer feed feed mixing It will have the advantage of supplying fluid smoothly and stably even during the movement of the feeder.

Such a drive transmission of the present invention is used to be mounted on one side of the feed mixing feeder 110 as shown in Figure 9, when the feed mixing feeder 110 is used in the traction form the input shaft 10 Is directly connected to a power shaft of a vehicle such as a tractor, so as to be operated by receiving a rotational force from the vehicle, and the feed mixing feeder 110 is configured to automatically reciprocate along a rail, if the feed mixing The rotational force of the driving motor 111 separately mounted on the feeder 110 is to be transmitted to the input shaft 10. In this case, a separate belt pulley 112 is mounted on the input shaft 10 to drive the above-described driving motor. What is necessary is just to connect the belt with 111.

As described above, the drive transmission device of the present invention can be applied to both a traction feed feeder and an automatic reciprocating feed feeder, so that the efficiency is very high. By increasing or decreasing the rotational speed for the most efficient form of mixing was achieved.
