Description

Agricultural machinery with a lifting device}

The present invention relates to an agricultural machine equipped with lifting means that can prevent the outer floor of the agricultural machine from contacting the ground surface by adjusting the height according to the condition of the ground surface when collecting hay, and more specifically, to the frame of the aircraft. An elevating means that can move the aircraft up and down depending on the condition of the ground surface is further installed on one side to prevent the wheels from entering the ground surface that is gradually eroded or caved in from wet soft ground and causing restrictions in movement. This is about the equipped agricultural machinery.

In general, a baler, which is one of the agricultural machines, is connected to the rear of an agricultural machine such as a tractor and towed, and collects hay (rice straw, feed plants, etc.) that has been mowed or scattered on the ground and turns it into a cylindrical stack. It is a device that performs. Furthermore, technology can be added that can combine the wrapping function to block the inflow of moisture or foreign substances by sealing the outside of the pile with a wrap.

A conventional baler has a connector device that can be connected to a tractor on one side of a main body equipped with a pair of wheels, and a hay unit that collects hay from the ground surface to make a pile of hay in the main body. The hay hay unit mounted on the main body is a device that can turn the collected hay into a cylindrical pile, and can further comprise a packaging means to pack the hay with a wrap or the like on the outside of the cylindrical pile.

In this conventional baler, the hay unit is placed adjacent to the ground surface because the hay unit must collect hay from the ground surface. However, depending on the condition of the ground surface, a problem arises in which the hay unit touches the ground surface, preventing smooth collection of hay.

In addition, when the baler moves on soft ground containing a large amount of moisture such as a rice paddy or field, the outer bottom surface of the baler body comes into contact with the ground surface due to the gradual erosion of the wheels, and mud etc. is deposited on the bottom surface of the main body. As it was attached, the weight of the baler itself increased, causing problems such as putting a load on the tractor connected to the baler.

Therefore, it is possible to respond according to the condition of the ground surface, preventing the wheel from easily falling into soft ground, and the baler body can be moved up and down so that the wheel can be easily separated even in an eroded state, improving workability. The development of agricultural machinery devices is necessary.

The present invention is an agricultural machine further equipped with a lifting means for collecting rice straw, hay, etc. from rice fields or fields after harvesting with a combine or manpower in rural areas, compressing and packaging them in a certain form, and then discharging them.

Referring to FIG. 1, the present invention includes a main body 100, an elevating means 200, an auxiliary drive wheel 300, a collecting unit 400, and a main wheel 500.

The main body 100 may correspond to a known baler or mower for collecting hay. The interior of the main body 100 is provided with a collecting unit 400 for collecting hay, a transport device for transporting the collected hay, a compression device for compressing the transported hay, and a packaging device for packaging the compressed hay.

The hay unit 400 is installed on one side of the main body 100 and moves up and down to collect hay located on the ground surface. The main body 100 is connected to the rear end of equipment capable of towing the main body 100, such as a tractor 10, and is provided with a propulsive force to move with the power of the tractor 10. In addition, auxiliary equipment such as a connecting rod and tow hook that can be connected to the tractor 10, etc. may be further formed on one side of the main body 100.

And, an auxiliary drive wheel 300 is further provided at the front end of the main body 100. The auxiliary drive wheel 300 has the shape of a small wheel that can be rotated, and prevents the lower end of the grass picker 400 from completely contacting the ground surface. That is, the purpose is to space the collecting unit 400 at a predetermined distance from the ground surface and maintain the distance from the ground surface at a constant distance.

Referring to Figures 1 and 2, a lifting means 200 is further formed on the lower surface of the main body 100. The elevating means 200 is a means to space the main body 100 at a predetermined distance from the ground surface. For example, when the main body 100 moves through a rice field or field, it may pass through wet soft ground or move through a sunken ground surface. At this time, as the main wheel 500 passes through soft ground, it gradually erodes or falls into a sunken ground surface, and the lower surface of the main body 100 comes into contact with the ground surface, causing an impact to the main body 100.

In addition, as wet soil, etc. adheres to the bottom and sides of the main body 100, the self-load of the main body 100 increases, causing the soft ground to gradually erode, and the tractor 10 towing the main body 100 Various problems occurred, such as high load.

For the purpose of solving this problem, an elevating means 200 is provided, and the elevating means 200 can space the main body 100 at a predetermined distance from the ground surface.

A main wheel 500 may be further formed in the elevating means 200, and the elevating means 200 adjusts the gap between the main wheel 500 and the main body 100 to separate the lower surface of the main body 100 from the ground surface. The spacing can be adjusted.

The main wheel 500 is mounted on the side of the lifting means 200 so that it can rotate without power. And, as the driving of the lifting means 200 is controlled by the user, the main body 100 can be selectively separated from the ground surface.

Referring to Figures 2 to 4, the lifting means 200 further includes a main fixture 210, a bracket 220, a rotating shaft 230, a wheel fixture 240, and a traction unit 250.

The main fixture 210 is fixedly installed on the lower surface of the main body 100. The main fixing bar 210 is spaced at regular intervals on the longitudinal side of the main fixing bar 211 and the main fixing bar 211 extending across the other side from one side of the main body 100, and the main fixing bar 211 ) and a plurality of auxiliary support bars 212 perpendicular to it.

The main fixing bar 211 and the auxiliary support bar 212 can be firmly fixed to the lower surface of the main body 100. When the main body 100 is tilted through the process of the elevating means 200 raising or lowering the main body 100 while the auxiliary support bar 212 is perpendicular to the main fixing bar 211, the center of gravity of the main body 100 can provide stable support.

The bracket 220 consists of a pair that is mutually symmetrical. The bracket 220 is fixed to both sides of the main fixture 210 and forms one body with the main fixture 210.

The rotation axis 230 extends in the same longitudinal direction as the main fixing bar 211 and has a cylindrical shape with a predetermined diameter. And the rotation axis 230 is disposed at a predetermined distance from the main fixing bar 211. At this time, both ends of the rotation axis 230 are respectively fixed to one end of a pair of brackets 230. As one side of each bracket 230 is coupled to the rotation axis 230, the bracket 230 can rotate in a circle around the rotation axis 230. An explanation for this will be provided below.

The wheel fixer 240 can rotate integrally with the rotation shaft 230 while having one end fixed to both ends of the rotation shaft 230. The main wheel 500 is mounted on the other side of the wheel fixture 230.

The traction unit 250 corresponds to a configuration whose length can be variably adjusted, such as a hydraulic or pneumatic cylinder or actuator. And one end of the traction unit 250 is rotatably coupled to the bracket 220, and the other end is also rotatably coupled to the wheel holder 240. As the length of the traction unit 250 is adjusted, the height of the rear end of the main body 100 can be adjusted by rotating the bracket 220 around the rotation axis 230 (see FIG. 3). The driving of the traction unit 250 is Users can selectively control it.

2 and 3, the bracket 220 includes a first plate 221, a second plate 222, and a traction support bar 223.

One end of the first plate 221 is fixed to the side of the main fixture 210 and the upper surface is seated on the lower surface of the main body 100. Preferably, the upper surface of the first plate 221 may be seated on the lower surface adjacent to the left and right edges of the main body 100.

Next, the second plate 222 is connected to the side of the first plate 221, and can be erected in a direction that intersects the first plate 221 so that one side is seated on the side portion adjacent to the left and right edges of the main body 100. .

And at one end of the second plate 222, a ring-shaped shaft housing 222-1 is further formed so that the rotation axis 230 passes through it. As the rotation axis 230 penetrates the shaft housing 222-1, the bracket 220 can rotate around the rotation axis 230. Bearings to reduce friction may be additionally provided between the shaft housing 222-1 and the rotating shaft 230.

The traction support 223 is formed on the other side of the second plate 222. One side of the traction unit 250 is coupled to the traction unit support 223 so that it can be rotated, and may preferably be hinged. The traction unit support 223 is preferably formed to surround one side of the traction unit 250 to prevent damage to the portion where the traction unit 250 is connected.

2 to 4, the wheel fixture 240 includes a first rod 241 and a second rod 242. The first rod 241 extends to a predetermined length, and an insertion hole 241-1 is further formed on one side so that the end of the rotation shaft 230 is inserted. The rotation shaft 230 is pressed into the insertion hole 241-1, or the outer surface of the rotation shaft 230 and the inner surface of the insertion hole 241-1 are in close contact with each other, and the first rod 241 is connected to the rotation shaft 230. We can form one body.

The second rod 242 extends from the other side of the first rod 241 and extends in a direction that intersects the direction in which the first rod 241 extends. And, the main wheel 500 is connected to the end of the second rod 242 so as to rotate.

[Example 1]

Referring to FIG. 5, the second rod 242 may further include a rotation angle adjusting portion 242-1 that can select the connection position of the traction portion 250. The rotation angle adjustment unit 242-1 refers to a portion in which a plurality of fastening holes 242-1h are arranged to be spaced apart at predetermined intervals. A fastening pin penetrating the second rod 242 is inserted into the fastening hole of the rotation angle adjusting unit 242-1, and while the fastening pin penetrates the other side of the traction unit 250, the other side of the traction unit 250 is 2 It can be rotated around the fastening pin while connected to the rod 242. The other side of the traction unit 250 is fastened to one of the plurality of fastening holes. At this time, the position where the other side of the traction unit 250 is coupled is adjusted and the separation between the main body 100 and the main wheel 500 is adjusted. The spacing can be adjusted.

For example, based on (a) of FIG. 5 , the traction unit 250 is first coupled to a fastening hole located adjacent to the rotation axis 230 among a plurality of fastening holes. Afterwards, when the length of the traction unit 250 increases, the bracket 220 rotates at a predetermined rotation radius.

On the other hand, when the traction part 250 is coupled to another fastening hole adjacent to FIG. 5 (b), if the length of the traction part 250 increases, the radius of rotation at which the bracket 220 rotates decreases. . (Here, the length that the traction part 250 extends is the same.)

Therefore, the gap h1 between the lower surfaces of the second rod 242 and the main body 100 shown in (a) of FIG. 5 is the distance between the second rod 242 and the main body 100 shown in (b) of FIG. The spacing (h2) of the lower surface has a large value.

[Example 2]

Referring to FIG. 6 , a first coupling bar 241-1 and a second coupling bar 241-2 may be further formed at one end of the first rod 241. The first coupling bar 241-1 is formed to protrude a predetermined length from one end of the first rod 241 to surround a portion of the outer side of the rotation shaft 230. And the second coupling bar 241-2 is spaced apart from the first coupling bar 241-1 by a predetermined distance and protrudes from one end of the first rod 241 by a predetermined length. The second coupling bar 241-2 is symmetrical to the first coupling bar 241-1 so as to surround the other outer portion of the rotation axis 230. Accordingly, the first rod 241 can be coupled to the rotation shaft 230 through the first and second coupling bars 241-1 and 241-2.

At this time, the distance between the first coupling bar (241-1) and the second coupling bar (241-2) is adjusted by penetrating through the first coupling bar (241-1) and the second coupling bar (241-2). A spacing adjustment pin 241-3 is further formed to fix/unlock the wheel fixer 240 to the rotation axis 230.

In order for the bracket 220 to be rotated by the operation of the traction unit 250, the wheel fixer 240 must remain fixed to the rotation axis 230. However, if the wheel fixture 240 can adjust the rotation radius to get closer to or away from the lower surface of the main body 100, the traction unit 250 operates because the main wheel 500 is coupled to the end of the wheel fixture 240. In the initial state, the separation distance between the main body 100 and the ground surface can be adjusted. Additionally, maintenance and servicing may become easier.

Referring to Figures 2, 3, and 6, a wheel shaft 260 coupled to the main wheel 500 is further formed on the second rod 242. The wheel shaft 260 includes a fixed shaft 261 and a wheel hub 262. The fixed shaft 261 extends to a predetermined length, and one end is coupled to the end of the second rod 242. A wheel hub 262 is mounted on the other end of the fixed shaft 261. Additional bearings, etc. may be installed between the fixed shaft 261 and the wheel hub 262. A plurality of fastening bolts 262-1 are protruding from one side of the wheel hub 262, and the main wheel 500 is fastened to the fastening bolts 262-1, thereby connecting the wheel hub 262 and the main wheel 500. are combined with each other. A coupling jaw 262-2 is formed to protrude on one surface of the wheel hub 262 facing the main wheel 500. In addition, a space is provided on the inner surface of the main wheel 500 into which the coupling jaw 262-2 can be inserted, and the main wheel 500 is connected to the fastening bolt 262-1 and the coupling jaw 262-2. Due to its configuration, it can be firmly fixed to the wheel hub 262.

The present invention with this configuration can selectively adjust the height of the bottom surface and the ground surface of the main body 100, preventing corrosion and damage to the bottom surface, and adjusting the height of the main body 100 appropriately according to the condition of the ground surface. can be adjusted, so that continuous dry collection of the weeding unit 400 can be performed, and there is an advantage that the main body 100 can easily escape from soft ground and sunken ground surfaces.
