Description

Forage compression and binding device {APPARATUS FOR COMPRESSING AND BANDING FORAGE CROPS}

The present invention relates to a forage compaction and binding device, and more particularly to a forage compression and binding device suitable for shaping a round bale of rice straw.

In Korea, feed is a balanced feed system suitable for a ratio of 60:40 for feed and abundant feed. To increase utilization, packing mechanization is important. Generally, a feeder compression and binding device, called a baler or baler, is a device that compresses and binds a crop for harvesting after harvesting to a predetermined shape to form a bale. The bales thus shaped are generally discharged from balers and stored in silage after additive treatment and vinyl winding.

In Korea, as of 2009, 2 to 2,200,000 tons of rice straw, which is 40% of rice straw production, is used as feed. In particular, by processing additives such as lactic acid bacteria, it is expected to reduce about 500kg of soybean compound feed per year. Therefore, silage preparation of rice straw using machinery such as balers should be strongly recommended.

On the other hand, balers are mainly produced in Europe and are imported in almost finished form. Therefore, the imported balers are provided with elements and structures that are not suitable for domestic crops such as rice straw, and thus, the operation of the apparatus is stopped, causing frequent problems in delaying work.

Specifically, in the case of the conventional European round baler, a series of rolls mounted in a cylindrical arrangement has a plurality of linear ribs on the surface. These linear ribs serve to provide a high frictional force with the surface of the bale being formed or the forage crop during rotation for bale shaping. However, the ribs formed on the surface of the roll just above the crop inlet, where the gap between the rolls is relatively large, causes the crop to flow back to the crop inlet frequently. This causes crop losses and even stops the operation of the device. In recent years, a rotary conveyor employing a rotor blade has an auger screw formed on the same axis as the rotor blade axis, and the auger screw usually takes the form of crossing the width of the chamber, that is, the width of the chamber. This is not suitable for relatively tough crops, such as rice straw, because they do not rotate more strongly at both ends of the crop inlet.

In addition, since the circular balers that are currently introduced in Korea have a medium-to-large size, the rotary feeder is not particularly suitable for rice straw produced in Korea. In addition, the existing domestic farms used a relatively small square baler. Therefore, since most of them are equipped with small tractors suitable for the square baler, the imported heavy and medium-sized round baler is difficult to tow and bale with the current tractor, and it is necessary to purchase a new horsepower tractor. . This is a problem that limits the practical application despite the many advantages of the circular baler.

Therefore, there is a need for a forage compression and binding device that is more suitable for rice straw.

The present invention is to solve such a problem, to provide a forage compression and binding device suitable for rice straw.

The present invention provides a forage compression and binding device that can minimize the loss of forage crops.

The present invention provides a feedstock compaction and binding device having a suitable size for rice straw as a whole, and smooth rotation of the crop at the crop introduction port.

The forage compression and binding device of the present invention comprises: a main frame; A rear door frame rotatably coupled to the main frame to enable rotation between a closed position and an open position; A bale shaping element comprising a series of rolls rotatably mounted in a cylindrical or arched arrangement on a side wall of the main frame and / or the rear door frame, the bale shaping element being in combination with the side wall of the main frame and / or the rear door frame. Providing a chamber in which a circular bale is formed, the bale forming element also providing a crop inlet through a gap of rolls located on the lower side of the front of the arranged series of rolls; And a crop supply system installed to supply the crops to the chamber through the crop inlet, wherein the roll immediately above the crop inlet is embossed.

Here, among the series of rolls, the rolls other than the upper portion of the crop inlet, the surface of which is embossed, are provided with a plurality of ribs which protrude in the longitudinal direction on the surface.

The crop supply system includes a pickup for picking up crops on the ground and a cutting transfer part for cutting the crops received from the pickup and transporting the crops to the chamber.

Wherein the cutting and transporting portion is: an axis disposed in a direction parallel to the series of rolls in front of the crop inlet, and on the shaft or on the shaft to transport the crop to the chamber through the crop inlet when the shaft is rotated. And a plurality of pairs of rotor blades arranged on the member installed to rotate as described above, and both the outer crops that extend the width of the crop inlet during rotation of the shaft to be transported within a range corresponding to the width of the crop inlet. A rotary conveyer comprising left and right auger screws installed on or on a member installed to rotate with the shaft; And cutter blades disposed between all or some pairs of blades of the plurality of rotor blade pairs, each cutter blade being mounted to cooperate with the corresponding rotor blade pairs to cut crops upon rotation of the plurality of rotor blade pairs. It includes a cutter.

Preferably the left and right augers are installed up substantially to both ends of the crop inlet.

Preferably, in the plurality of rotor blade pairs, the first and second pairs from the left auger screw and the first and second pairs from the right auger screw are spaced apart from the left and right auger screws and the remaining rotors from each other. It is narrower than the gap between the blade pairs.

The forage compression and binding device of the present invention has the effect of maximally suppressing a phenomenon in which the crop under bale flows back into the crop inlet in the chamber. Therefore, it is possible to minimize the downtime of the device due to backflow and to minimize the occurrence of crop loss. In addition, the device as a whole can have a small size, there is an effect that can smoothly carry out the rotational transfer of rice straw at the crop inlet. As a result, the present invention has the effect of providing a forage compression and binding device which is very suitable for rice straw. Therefore, domestic users can perform effective baling work using the forage compression and binding device of the present invention with the existing tractor.

1A, 1B, 2, and 3, the forage compression and binding device 100 according to a preferred embodiment of the present invention is towed and moved to the farm tractor 200 through the hitch 162, each element The driving force of the tractor 200 is also transmitted to the gearbox 164. The forage compression and binding device 100 picks up crops such as rice straw placed on the ground while moving in rice fields or fields to form a bale and binds it, and then opens a rear door as shown in FIG. 1B to discharge a bale (not shown). The bound round bales are typically wrapped in silos at outdoor sites. This forage compression and binding device is significantly reduced labor than when using a conventional square baler.

The forage compression and binding device 100 according to the preferred embodiment of the present invention includes a main frame 110 and a rear door frame 120, as shown in FIGS. 1A to 5. In general, the main frame 110 is supported by a pair of wheels 150, the rear door frame 120 is rotatably coupled to the main frame 110 is possible to rotate between the closed position and the open position. The forage compression and binding device 100 forms and binds the bale in a closed state, and then opens the rear door frame 120 to discharge the formed bale. The opening and closing of the rear door frame 120 may be made by a conventional device such as a hydraulic cylinder (not shown), and a detailed description thereof will be omitted.

On the side walls of the main frame 110 and the rear door frame 120, a series of rolls 130, 130F and 130L in a cylindrical arrangement are mounted as bale forming elements. The preferred embodiment shown is provided with a series of rolls 130, 130F and 130L mounted in a cylindrical arrangement as a bale forming element. This cylindrical arrangement of rolls and sidewalls of the frames 110 and 120 provide a fixed chamber 140 of fixed size.

However, the present invention is not limited to the illustrated embodiment and in other examples of the present invention may be applied to a variable chamber in which some roll arrangements and other elements such as chains or belts are mixed. In this case, the rolls may be mounted only in the main frame 110 in an arcuate or arcuate arrangement.

As can be seen in FIGS. 4 and 5, the crop introduction opening E is provided through the spacing of the rolls 130F and 130L located on the lower front side of the series of rolls. In the forage compression and binding device 100 according to the preferred embodiment of the present invention, the surface of the roll 130L immediately above the crop introduction opening E is made of embossing, which will be described in more detail below.

The forage compression and binding device 100 of the preferred embodiment includes a crop supply system 170 for supplying crops to the chamber 140 through the crop inlet E. Crop supply system 170 is composed of a pickup unit 180 and the rotational transfer unit 190. The rotation transfer unit 190 of the present invention includes the improvements, which will be described later.

As described above, in the forage compression and binding device 100 according to the preferred embodiment of the present invention, the roll 130L of the upper portion of the crop introduction opening E is an embossing roll. This is in contrast to having the ribs 134 formed on the surface in the remaining rolls 130, including the first roll 130F. In particular, the ribs 134 have a plurality of shapes arranged along the circumference of the roll 130, and they smoothly form the baling operation by serving as teeth to increase friction with the surface of the bale being formed. However, the roll 130L of the upper portion of the crop introduction opening E frequently causes problems when linear ribs are formed on the surface like the other rolls. For example, because the first roll 130F, the next roll due to the crop introduction opening E, is considerably spaced apart, in the case of rice straw, in the conventional apparatus, the ribs 134 of the surface are placed under the crop being bale-formed. The phenomenon of biting into the crop introduction opening (E) occurs frequently. Therefore, the preferred embodiment of the present invention implements the embossed surface by forming a plurality of protrusions 132 on the surface of the roll 130L immediately above the crop introduction opening (E). This embossed surface can minimize the crop backflow problem described above while providing adequate friction to the surface of the crop and bale being molded. Such embossing rolls may have various patterns according to the type of crops, as shown in FIGS. 7A and 7B, and preferably have a protrusion size of about hemispherical degree. For example, when the crop is thin and delicate, an embossing roll 131L having a coarse protrusion 132 may be applied as shown in FIG. 7B.

Hereinafter, the crop supply system 170 applied to the forage compression and binding device 100 of the present invention will be described again. Crop supply system 170 is composed of a pick-up unit 180 for picking up the crop on the ground and a cutting transfer unit 190 for cutting the crop received from the pick-up unit 180 and transported to the chamber 140. The pickup unit 180 may have a reel having a plurality of rakes 182, and the plurality of rakes 182 may be disposed between the spaced bands 181. Detailed description of the pickup unit 180 will be omitted. The forage compression and binding device 100 of the present invention includes an improvement in the cutting transfer unit 190 in the crop supply system 170.

4, 5, 6, 8A, and 8B, the cutting feeder 190 includes a rotary feeder 190 and the cutter 193 for rotationally transporting the crops transferred from the pickup (180). The rotary transfer unit 190 includes a plurality of rotor blade pairs 191 for rotating and transferring the crops transferred from the pickup unit 180 and left and right auger screws 192L and 192R for collecting the crops inward. These rotor blade pairs 191 and augerscrews 192L and 192R are installed on one axis. That is, as can be seen in FIG. 8A, the shaft 195 is installed on the shaft 195 disposed in parallel with the series of rolls 130, 130F and 130L in front of the crop introduction opening E. It is possible to install all the way to rotate. For example, the augerscrews 192L and 192R may have a core 196 connected to the shaft 195. The rotorblade pairs 191 may also be formed on a pipe 197 connected to the core 196 of the augerscrews or to the shaft 195.

The left and right auger screws 192L and 192R correspond to the width W of the crop inlet E for both outer crops leaving the width W of the crop inlet E during rotation of the shaft 195. It is formed to transfer into the range W '.

The left and right auger screws 192L and 192R are provided to each boundary line of the range W 'corresponding substantially to the width W of the crop introduction opening E. FIG. In other words, the left and right auger screws 192L and 192R are formed up to a line which does not violate the range W '. As a result, the left and right auger screws (192L and 192R) are substantially installed up to both ends of the crop introduction opening (E). This, together with the arrangement of the rotor blade pair 191 to be described later will have a configuration suitable for the rotational transport of long crops, such as rice straw.

The plurality of rotor blade pairs 191 applied to the forage compression and binding device 100 according to the preferred embodiment of the present invention, as can be seen in Figures 8A and 8B, to the auger screws 192L and 192R. Closely located pairs are relatively shorter apart than others. More specifically, the first and second pairs from the left augerscrew 192L and the first and second pairs from the right augerscrew 192R of the plurality of rotor blade pairs 191 are spaced from the left and right augerscrews. The spacing (B) between (A) and each other is smaller than the spacing between the remaining rotor blade pairs. Such a configuration may be said to be more suitable for a relatively tough crop such as rice straw along with the configuration of the augerscrews 192L and 192R as described above. In other words, a tough crop such as rice straw needs to be given a relatively greater rotational force near the border between the crop inlet and the auger's screw. Furthermore, the forage compression and binding device 100 according to the present invention may be said to be suitable for cutting and rotating conveying rice straws having a height of about 1 m with an arrangement of nine rotor blade pairs 191 together with the auger screw configuration as described above. Can be.

4 to 6, the cutter 193 is mounted such that the cutter blades are disposed between all or some pairs of blades of the plurality of rotor blade pairs 191. Each cutter blade of the cutter 193 cooperates with the corresponding rotor blade pair to cut the crop when the plurality of rotor blade pairs 191 rotate.

The rotary feeder 190 of the present invention further includes a scraper 194. This scraper 194 scrapes the crops that are wound around the pipe 197 between the rotorblade pairs 191.

In the foregoing detailed description of the present invention, specific embodiments have been described. However, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the present invention.
