Description

Technical Field

[0001] The present invention relates to the technical field of rice equipment, and more specifically, to a rice baler. Background Art

[0002] Rice baler is a kind of rice harvesting machinery, which is the key equipment of rice segmented harvesting process. It is a small and medium-sized agricultural machinery with low price, which can meet the needs of domestic agricultural cooperatives and individual farmers.

[0003] Rice harvesting machinery has gone through a difficult development process from simple to complex, from low-level to high-level, and from backward to advanced. The early mechanized rice harvesting method was to directly harvest after the frost. The disadvantages were high moisture content in rice, high drying cost, high pressure in the drying field, and the risk of being covered by snow. In the full mechanization of paddy fields, the rice harvesting problem is the key to affecting the high yield and harvest of rice. Large harvest losses, high moisture content in grains, and decreased quality have led to a significant reduction in benefits, which has become a bottleneck restricting the improvement of rice quality, increase in yield and efficiency. The current mechanized rice harvesting process is mechanized segmented rice harvesting. Segmented rice harvesting can extend the effective harvesting period, speed up the rice harvesting progress, reduce rice moisture, improve quality, achieve safe storage, increase rice sales prices, and increase benefits, thereby ensuring a high yield and harvest of rice. This technology has been recognized by rice farmers and has been widely used in rice harvesting. Compared with the combine harvester, the rice segmented harvesting equipment has the following advantages: first, the cost is low and farmers can afford it; second, the rice can be dried naturally after harvesting without the need for drying equipment, thus saving production investment; third, the rice straw can be returned to the field or recycled; fourth, the segmented harvesting machinery can be used as a supplementary model for the combine harvester.

[0004] The function of the rice baler is to bundle the rice (including ears) and place them in the field for natural drying. When the moisture content of the rice drops to about 15%, the semi-feed thresher is used to thresh the rice and baling is performed at the same time. The baling rope is tied to the root and stem.

[0005] The original rice baler used a C-type knotter, which had a low baling rate, and there were problems with loose knots and easy disengagement. At the same time, the knotter parts were easily worn. Some companies improved the C-type knotter and changed it to a D-type knotter for dead knots. The disengagement problem was solved, but the adaptability of the baling rope was poor. The baling rate of thin ropes, hemp ropes and recycled ropes was not high, less than 90% of the baling rate; after the machine ran for a period of time, the knotter baling rate decreased, and loose bales occurred continuously. Farmers needed to re-bundle, which was time-consuming and laborious. At the same time, the kicking mechanism broke, and the front and rear bales adhered to each other; it affected the shape of the bale, and a large amount of ears fell off. In addition, the sprockets of the existing baler were set on both sides of the baler, with many components and more troublesome equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a rice baler that improves the baling rate of a rice baler, improves the adaptability of a knotter rope, and satisfies the adaptability of ropes of various materials and various specifications and sizes, and solves the problem of straw bale adhesion.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] See also Figure 1-Figure 5As shown, the present invention provides a rice baler, including a frame assembly 9, in which a transmission chain mechanism, a grass picking shaft assembly 4, a knotting shaft assembly 7, a trigger device assembly 6 and a grass baffle assembly 8 are arranged. The transmission chain mechanism is arranged on one side of the frame assembly 9, which reduces the difficulty of assembly. The transmission chain mechanism includes a chain 2, a driving sprocket 1, a grass picking sprocket 3 and a knotting sprocket 5. The chain 2 is used for transmission connection between the driving sprocket 1, the grass picking sprocket 3 and the knotting sprocket 5. The grass picking shaft assembly 4 and the grass picking chain assembly 6 are connected to each other. The wheel 3 is fixedly connected, the knotting shaft assembly 7 is movably hinged with the trigger device assembly 6, the grass baffle assembly 8 is fixedly installed at one end of the upper part of the frame assembly 9, and the grass kicking rocker mechanism is a four-link structure, which includes a grass kicking crank 713, a grass kicking needle 714, a first grass kicking connecting rod 709, a second grass kicking connecting rod 702, a first support 710 of the grass kicking connecting rod and a second support 703 of the grass kicking connecting rod. One end of the grass kicking crank 713 is connected to the knotter assembly 7, and the size of the grass kicking crank 713 is determined by simulation to ensure The kicking crank 713 can kick the rice bale out of the frame by 20 mm. The other end of the kicking crank 713 is movably hinged with the kicking needle 714. The two ends of the upper part of the kicking needle 714 are respectively movably hinged with the first kicking connecting rod 709 and the second kicking connecting rod 702. The two ends of the lower part of the kicking needle 714 are fixed with needles. The other ends of the first kicking connecting rod 709 and the second kicking connecting rod 702 are respectively connected to the first kicking connecting rod support 710 and the second kicking connecting rod support 703. The second support 703 of the grass-kicking connecting rod is welded to the outer surface of the frame assembly 9, the grass-kicking crank 713 rotates together with the knotter mounting shaft 7, the grass-kicking needle 714 moves together with the grass-kicking crank 713, the first grass-kicking connecting rod 709 and the second grass-kicking connecting rod 702 move together with the grass-kicking crank 713. When knotting is completed, since the optimal size of the grass-kicking crank 713 is determined through simulation, when it swings, the tip of the needle of the grass-kicking needle 714 exceeds the frame of the frame assembly 9, thereby ensuring that the rice bale can be kicked out.

[0027] The problem of grass bale sticking is mainly solved from the kicking mechanism. In the original prior art, the kicking mechanism adopts a curved guide rail structure, and the roller moves in the curved guide rail. As the working time increases, the curved guide rail will inevitably wear. When the wear reaches a certain amount, the kicking action will change, causing the kicking action and the timing of kicking to change, or the roller and the curved guide rail are abnormally rubbed and worn, and the friction coefficient increases, which will cause the kicking action to be delayed, and the grass bale will stick. In order to ensure that the kicking action is powerful and the previous grass bale is not skewed, a short kicking needle of the kicking mechanism is positioned at the rice ear position to ensure that the grass bale is thrown in the horizontal direction.

[0028] In this embodiment, the frame assembly 9 includes a frame 905, a feed plate 906, a discharge plate 907, a first grass pressing plate 901, a second grass pressing plate 902, a third grass pressing plate 904 and a knotter guard plate 903.

The signal sending fixed handle 606 is fixed to the knotter mounting shaft 701. The signal sending fixed handle 606 rotates, driving the knotter mounting shaft 701 to rotate. The signal sending movable handle 607 rotates to drive the long connecting rod 610 to rotate. The long connecting rod 610 rotates to drive the short connecting rod 613 to rotate. The short connecting rod 613 transmits the motion to the rope feeding needle shaft 605. The rotation of the rope feeding needle shaft 605 drives the rope feeding needle 601 to move. The rope feeding needle 601 carries the baling rope, and the rope feeding needle 601 sends the baling rope to the knotter 707 for knotting.

[0039] Combined action one: the driving sprocket 1 rotates, and the power is transmitted to the grass-pulling sprocket 3 through the chain 2. The long grass-pulling needles 409 and the short grass-pulling needles 408 pull the rice to the bottom of the first grass-pressing plate 901, the second grass-pressing plate 902, the third grass-pressing plate 904, and the knotter guard plate 903. The grass-blocking plate assembly 8 blocks the incoming rice. When the amount of rice is not enough to rotate the trigger needle 602 into place, the pull rod 608 blocks the rotation of the movable sending handle 607 and the fixed sending handle 606, and the knotter mounting shaft 701 does not rotate, and the baling action is not performed at this time.

[0040] Combined action two: the active sprocket 1 rotates, and the power is transmitted to the grass-pulling sprocket 3 through the chain 2. The long grass-pulling needle 409 and the short grass-pulling needle 408 pull the rice to the bottom of the first grass-pressing plate 901, the second grass-pressing plate 902, the third grass-pressing plate 904, and the knotter guard plate 903. The grass-blocking plate assembly 8 blocks the entering rice. When the amount of rice can make the trigger needle 602 rotate into place, the trigger shaft 604 rotates, driving the trigger pull ring 612 to rotate, and pulling the connecting plate 611 and the pull rod 608 downward. The pull rod 608 cannot block the movable handle 607 for sending a signal, so that the movable handle 607 for sending a signal and the fixed handle 606 for sending a signal rotate together with the knotting sprocket 5.

[0041] The sending movable handle 607 rotates, driving the long connecting rod 610 and the short connecting rod 613 to move, driving the rope feeding needle shaft 605 to rotate, and the rope feeding needle 601 is fixed to the rope feeding needle shaft 605. The rope feeding needle 601 rotates along the rope feeding needle shaft 605. The rope feeding needle 601 carries the baling rope, and the rope feeding needle 601 sends the baling rope to the knotter 707 for knotting.

[0042] The knotting fixed handle 606 is fixed together with the knotter mounting shaft 701. When the sending fixed handle 606 rotates, the knotter mounting shaft 701 also rotates, and the wire shifting cam 7601 rotates together with the knotter fixed shaft 701. The wire shifting cam 7601 drives the roller 7602 to move in the wire shifting cam 7601 groove, and the roller 7602 drives the wire shifting rod 7603 to swing, thereby driving the wire shifting push rod 7605 to do reciprocating motion, and the wire shifting push rod 7605 drives the wire shifting plate 7606 to do reciprocating motion.

[0043] The knotting fixing handle 606 is fixed to the knotter mounting shaft 701, and the knotter toothed disc 7704 rotates with the knotter mounting shaft 701, and the knotter toothed disc 7704 drives the beak 7705 and the worm 7702 to rotate. When the rope feeding needle 601 sends the baling rope to the knotter 707, the worm 7702 drives the rope clamp 7701 to clamp the baling rope, the wire shifting plate 7606 shifts the baling rope to a certain angle, and the beak 7705 rotates to tie the knot; when the knotting is completed, the wire shifting plate 7606 returns to the non-wire shifting state, and the rope feeding needle 601 also exits the knotter 707, completing the knotting action. The grass kicking needle 714 kicks the knotted rice bundle out of the discharge plate 907, completing the knotting action of a rice bundle.
