Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a reed bundling and stacking device and method and a harvester. Background Art

[0002] Reed is a tall grass that mostly grows in water and land. It has a fine texture and is rich in cellulose. Mature reeds can not only be used as industrial raw materials for papermaking, building materials, and artificial fibers, but the processed reed stems can also be woven into various handicrafts, which have extremely high economic and practical value. At present, reeds grown in wetlands in my country are mainly harvested manually, and mechanical harvesting is not widely used. Manual harvesting is time-consuming and labor-intensive, and has low production efficiency. The level of mechanical harvesting lags far behind that of foreign countries, especially in the integrated technology of whole-stalk harvesting.

[0003] At present, in addition to manual harvesting, the degree of mechanized harvesting of reeds is not high. People need to manually put the bundled reeds into the material box. The labor intensity is too high, and at least one person is needed to transport and one person to stack the reeds. A machine is equipped with two workers. The working environment of people on the machine is also unsafe. When the material box is full, the reeds are delivered to the loading and unloading truck by people. One harvest requires multiple people to complete, resulting in excessive labor intensity and time-consuming and labor-intensive work. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a reed bundling and stacking device and method, which can tie the reeds into small bundles and stack them vertically or flatly in a material box device, and then tie the knotted small bundles of reeds into large bundles. After the large bundles are tied, the machine unloads the reeds, thereby improving the harvesting efficiency.

[0005] The present invention also provides a harvester comprising the reed baling and stacking device.

[0018] Further, the wire clamp includes a first wire clamp, a second wire clamp, a third wire clamp and a fourth wire clamp;

[0025] The rotating shaft is installed on the side of the material box housing close to the material box door, and one end is connected to the frame of the harvester through a bearing;

[0028] Furthermore, a wire box, a displacement sensor, a photoelectric sensor and a wire box switch are provided on the material box housing;

[0029] The wire box is provided with a steel wire;

[0030] The displacement sensor is used to detect the rising height of the wire clamp. When the displacement sensor detects that the wire clamp rises to a preset height and transmits a signal to the control unit, the control unit controls the wire box switch to open the wire box, and the steel wire falls from the wire box. After the photoelectric sensor senses that the steel wire has fallen, it transmits a signal to the control unit, and the control unit controls the wire box switch to close the wire box.

[0031] A harvester comprises the reed bundling and stacking device.

[0032] A control method according to the reed bundling and stacking device comprises the following steps:

[0033] The knotter knots the reeds into small bundles;

[0034] The control unit controls the driving component of the stacking mechanism to drive the first mechanical clamp and the second mechanical clamp to move along the X-axis direction, the Y-axis direction, and the Z-axis direction, so that the first mechanical clamp and the second mechanical clamp clamp the small bundles of reeds and stack them into the material box;

[0035] The control unit controls the wire clamps of the bundling mechanism in the material box to clamp the steel wires, and the driving mechanism drives the wire clamps to tie small bundles of reeds into large bundles.

[0036] In the above scheme, when vertical stacking is adopted, the stacking mechanism is controlled by the control unit to stack several small bundles of reeds vertically into the material box;

[0037] When the number of small bundles of reeds reaches a preset value, the control unit controls the driving mechanism to drive the wire clamp to rise. When the displacement sensor detects that the wire clamp rises to a preset height and transmits a signal to the control unit, the control unit controls the wire box switch to open the wire box, and the steel wire falls from the wire box. After the photoelectric sensor senses that the steel wire has fallen, it transmits a signal to the control unit, and the control unit controls the wire box switch to close the wire box.

[0038] The control unit controls the driving mechanism to drive the wire clamp to tie several small bundles of reeds into a large bundle.

[0039] In the above scheme, the control unit controls the ninth driving mechanism so that the heights of the relatively arranged first wire clamp and the second wire clamp are inconsistent and the steel wire is clamped; the control unit controls the relatively arranged third wire clamp and the fourth wire clamp to loosen the steel wire, while the first wire clamp and the second wire clamp continue to clamp the steel wire and move toward each other, so that the steel wire is wrapped around and pressed against the large bale of reeds to complete the bundling.

[0040] In the above scheme, when straight stacking is adopted, the stacking mechanism is controlled by the control unit to stack several small bundles of reeds straightly into the material box;

[0041] When the number of small bundles of reeds reaches a preset value, the control unit controls the ninth driving mechanism to drive the wire clamp to rise to a preset position, the first wire clamp and the second wire clamp are connected to the same steel wire, and the third wire clamp and the fourth wire clamp are connected to the same steel wire;

[0042] The first wire clamp and the second wire clamp are controlled to be staggered in the Y-axis direction, the third wire clamp and the fourth wire clamp are controlled to be staggered in the Y-axis direction, the first wire clamp and the second wire clamp move toward each other, the third wire clamp and the fourth wire clamp move toward each other, the reed bundle is tightened by the steel wire, and the two steel wires act at the same time, thereby increasing the binding strength of the large reed bundle; then, under the action of the twelfth driving mechanism, the first wire clamp and the second wire clamp move in opposite directions in the Y-axis direction, the third wire clamp and the fourth wire clamp move in opposite directions in the Y-axis direction, and finally, under the action of the eleventh driving mechanism, the first wire clamp and the second wire clamp move in opposite directions in the X-axis direction to form a loop, and the third wire clamp and the fourth wire clamp move in opposite directions in the X-axis direction to form a loop, thereby completing the knotting of the reed bundle.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The present invention clamps the bundled reeds by mechanical clamps on both sides. The left and right mechanical clamps realize the clamping and loosening of the reed bundles through driving components. After the reed bundles are clamped, they are stacked vertically or horizontally in the material box. When the material box is stacked until the stacking is completed, the small bundles of reeds are tied into large bundles by the bundling mechanism of the material box. The present invention uses mechanical clamps to replace manual stacking of reed bundles, which greatly reduces the labor intensity, improves the working efficiency and intelligence level of the reed harvester, and provides good technical support for the intelligent harvesting of the reed harvester. The mechanical clamps of the present invention can realize both vertical and horizontal stacking, and have a flexible structure, which is suitable for material box devices that unload materials in different orientations.

[0045] 2. The present invention can control the driving mechanism through the control unit to drive the lifting and lowering of one side of the material box shell, so that the material box shell rotates around the rotating shaft and the reed bundles tied into large bundles are unloaded from the material box door; the present invention adopts an automatic unloading material box to replace the traditional material box, and no manual operation is required. After the large bundles are tied, they are separated from the material box and put into the field through side rotation and their own gravity.

[0046] 3. The present invention adopts a driving mechanism to drive four wire clamps to move to complete the bundling work, which has a simple structure and is easy to operate.

[0047] 4. The wire box of the present invention has a simple structure. When vertical bundling is required, the wires are automatically released through the wire box, which saves labor and improves efficiency.

[0048] Note that the description of these effects does not prevent the existence of other effects. One embodiment of the present invention does not necessarily have all of the above effects. Effects other than the above can be clearly seen and extracted from the description of the specification, drawings, claims, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Example 1

[0069] Figure 1 The figure shows a preferred embodiment of the reed bundling and stacking device, which includes a knotter 2, a material box 3, a stacking mechanism 4 and a control unit 7;

[0070] The knotter 2 is located behind the header 1 and the conveying mechanism; the stacking mechanism 4 is located between the knotter 2 and the material box 3; the knotter 2 is used to tie the reeds into small bundles, and the stacking mechanism 4 is used to stack the small bundles of reeds vertically or flatly into the material box 3; the material box 3 is used to tie the small bundles of reeds into large bundles, such as Figure 2 As shown;

[0071] The control unit 7 is connected to the material box 3 and the stacking mechanism 4 respectively.

[0072] like Figure 3 As shown, according to this embodiment, preferably, the stacking mechanism 4 includes a first mechanical clamp 401, a second mechanical clamp 402, and a driving component connected to the control unit 7;

[0073] The first mechanical clamp 401 and the second mechanical clamp 402 are arranged opposite to each other, and the first mechanical clamp 401 and the second mechanical clamp 402 are respectively connected to the driving components, and the driving components are used to drive the first mechanical clamp 401 and the second mechanical clamp 402 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction. The first mechanical clamp 401 and the second mechanical clamp 402 clamp the small bundles of reeds and stack them into the material box 3.

[0074] Further, the driving component includes a first driving mechanism 403, a second driving mechanism 404, a third driving mechanism 405, a fourth driving mechanism 406, a fifth driving mechanism 407, a sixth driving mechanism 408, a first actuator 409 and a second actuator 410 respectively connected to the control unit 7;

[0075] The first mechanical clamp 401 is connected to one end of the third driving mechanism 405, the other end of the third driving mechanism 405 is connected to one end of the first driving mechanism 403 through the first actuator 409, the other end of the first driving mechanism 403 is connected to one end of the fifth driving mechanism 407, and the other end of the fifth driving mechanism 407 is arranged on the harvester chassis 6 and close to the knotter 2; the first driving mechanism 403 is used to adjust the movement of the first mechanical clamp 401 along the X-axis direction, the third driving mechanism 405 is used to adjust the movement of the first mechanical clamp 401 along the Y-axis direction, and the fifth driving mechanism 407 is used to adjust the movement of the first mechanical clamp 401 along the Z-axis direction, and the first actuator 409 is used to drive the third driving mechanism 405 to drive the first mechanical clamp 401 to rotate, so that the first mechanical clamp 401 is vertical or straight;

[0076] The second mechanical clamp 402 is connected to one end of the fourth driving mechanism 406, the other end of the fourth driving mechanism 406 is connected to one end of the second driving mechanism 404 through the second actuator 410, the other end of the second driving mechanism 404 is connected to one end of the sixth driving mechanism 408, and the other end of the sixth driving mechanism 408 is arranged on the harvester chassis 6 and close to the knotter 2; the second driving mechanism 404 is used to adjust the movement of the second mechanical clamp 402 along the X-axis direction, the fourth driving mechanism 406 is used to adjust the movement of the second mechanical clamp 402 along the Y-axis direction, and the sixth driving mechanism 408 is used to adjust the movement of the second mechanical clamp 402 along the Z-axis direction. The second actuator 410 is used to drive the fourth driving mechanism 406 to drive the second mechanical clamp 402 to rotate, so that the second mechanical clamp 402 is vertical or straight.

[0077] According to this embodiment, preferably, the first driving mechanism 403 , the second driving mechanism 404 , the third driving mechanism 405 , the fourth driving mechanism 406 , the fifth driving mechanism 407 , and the sixth driving mechanism 408 are hydraulic cylinders.

[0078] In one embodiment of the present invention, each hydraulic cylinder is provided with a linear displacement sensor for detecting the extension and contraction amount of the hydraulic cylinder and feeding back to the control unit 7. The control unit 7 adjusts the extension and contraction amount of the hydraulic cylinder according to a preset value.

[0079] According to this embodiment, preferably, the first actuator 409 and the second actuator 410 are hydraulic motors.

[0080] In one embodiment of the present invention, the stacking process of the stacking mechanism 4 is as follows:

[0081] The position of the mechanical clamp is adjusted to the initial position, i.e., the reed bundling position, by the extension and retraction of the first driving mechanism 403 and the second driving mechanism 404. Then, the left and right mechanical clamps are adjusted to clamp the reed bundles and transport them to the material box for stacking.

[0082] In one embodiment of the present invention, the baling position is just beside the material box 3, and the initial position of the mechanical clamp can be readjusted according to the baling position. Therefore, the displacement of the first driving mechanism 403 and the second driving mechanism 404 at this initial position is the two x coordinates of the first row of stacking, and then the third driving mechanism 405 and the fourth driving mechanism 406 start to work, and the extension hydraulic cylinder drives the mechanical clamp to move in the y-axis direction to stack the reeds in sequence. All hydraulic cylinder displacements are measured and positioned using linear displacement sensors.

[0083] like Figure 4 As shown, in one embodiment of the present invention, the stacking mechanism 4 stacks small bundles of reeds vertically or flatly in an orderly manner in the material box 3, and rationally utilizes the space of the material box 3 to stack the reed bundles, which is conducive to the efficient recovery of reeds and also facilitates the subsequent knotting of small bundles to large bundles in the material box 3.

[0084] In one embodiment of the present invention, the stacking mechanism 4 realizes the vertical stacking of reed bundles in the following manner: first, the radius of the bundled reed bundle is known to be R, which is determined by the knotter, and the length of the material box in the y-axis direction is L1, then the number of reed bundles that can be stacked in the material box can be calculated to be n, n = (L1 / 2R), n is an integer, and all decimals are discarded. Starting from the initial position of the mechanical clamp, that is, the initial displacements of the first drive mechanism 403 and the second drive mechanism 404 are x1 and x2 respectively, then the displacements of the third drive mechanism 405 and the fourth drive mechanism 406 of the first stacked reed bundle are L1-R, and the real-time position relationship of the mechanical clamp stacking reed bundles can be characterized by three parameters, which are: the displacement of the first drive mechanism x 左 , displacement of the second driving mechanism x 右 , the third drive mechanism is displaced or the fourth drive mechanism is displaced y, the initial position of the third drive mechanism 405 and the fourth drive mechanism 406 is on the edge of the material box 3, and the displacement is zero at this time. The three parameters corresponding to the first reed bundle stacked in the first row are: x1, x2, L1-R, and the three parameters corresponding to the second reed bundle stacked in the first row are x1, x2, L1-3R, until the first row is stacked to the nth reed bundle, and the corresponding three parameters are x1, x2, L1-(2n+1)R.

[0085] Parameters of the first reed bundle in the first row: x1, x2, L1-R,

[0086] Parameters of the first reed bundle in the first row: x1, x2, L1-3R,

[0087] …

[0088] Parameters of the nth reed bundle in the first row: x1, x2, L1-(2n+1)R.

[0089] Each time the mechanical clamp reaches the position for stacking reed bundles, the second mechanical clamp 402 is released by adjusting the second driving mechanism 404, and then returns to the initial position to clamp and deliver the reed bundle again. In order to avoid the second mechanical clamp 402 from touching the right bin cover when stacking the last row of reed bundles, sufficient space needs to be left. Generally, the minimum space distance for the device not to touch is h, and the number of rows that can be stacked is n1 = (L2-h) / 2R. n1 is an integer, and all decimals are discarded, then:

[0090] Parameters of the first reed bundle in the second row: x1+2R, x2-2R, L1-R,

[0091] Parameters of the first reed bundle in the second row: x1+2R, x2-2R, L1-3R,

[0092] ………

[0093] Parameters of the nth reed bundle in the second row: x1+2R, x2-2R, L1-(2n+1)R,

[0094] Arrange the reed bundles in the n1th row in sequence, and the parameters become:

[0095] Parameters of the first reed bundle in row n1: x1+2n1R, x2-2n1R, L1-R,

[0096] Parameters of the first reed bundle in row n1: x1+2n1R, x2-2n1R, L1-3R,

[0097] ………

[0098] Parameters of the nth reed bundle in the n1th row: x1+2n1R, x2-2n1R, L1-(2n+1)R.

[0099] like Figure 5 As shown, in one embodiment of the present invention, the mechanical clamp is made into an arc shape, which is conducive to contact with the reed bundle and is convenient for clamping, and the installation heights of the mechanical clamps on both sides should be arranged high and low, so that not only the vertical clamping and stacking of the reed bundles can be ensured, but also the straight clamping of the reed bundles without interference after the mechanical clamps are rotated 90 degrees, ensuring that one mechanical clamp is on the top and the other mechanical clamp is on the bottom for straight stacking.

[0100] In one embodiment of the present invention, when the reed bundle needs to be stacked flat, the mechanical clamp first vertically clamps the reed bundle, and then the hydraulic motor rotates the shaft connected to the mechanical clamp, driving the shaft to rotate 90 degrees, and rotates the two vertical mechanical clamps to a flat position, and then under the action of the left second driving mechanism 404, the reed bundle is transported to the first row of the material box, in order to ensure that the mechanical clamp below has enough space to move and retract, and ensure that the reed bundle falls. Therefore, a considerable space should be reserved from the left side of the material box 3 to ensure that the current mechanical clamp below can move and exit, and this space distance is set to m, and the m value is related to the length of the reed bundle and the width of the material box.

[0101] like Figure 6 As shown in the figure, the width of the material box in the x-axis direction is L2, the height of the reed bundle is k, and when the mechanical clamp stacks the reed bundle flatly, the position of the lower mechanical clamp is basically near the root of the reed bundle. Therefore, the expansion space reserved for the mechanical clamp is L2-k, and L2-k needs to be greater than the height of the mechanical clamp. When the lower mechanical clamp moves toward the remaining space, the upper mechanical clamp expands and contracts downward under the action of the upper and lower position adjustment hydraulic cylinders, which can apply downward force to the reed bundle. The simultaneous movement in two directions can ensure that the reed bundle is released from the mechanical clamp and stacked flatly, and then returns to the initial position to clamp the second reed bundle for sequential stacking. The y parameter of the second reed bundle in the first row becomes y-3R, and the left x of the reed bundle is y-3R. 左 The parameter is (L2-k)+x1, the right parameter x 右 Then it is necessary to move L2-k to the right based on the original vertical clamping cylinder displacement x2, that is, x 右 is x2-(L2-k).

[0102] The number of rows that can be stacked on each layer is n, n = L1 / 2R. After the first layer is stacked, the stacking starts from the first reed bundle position on the second layer. The three parameters of each row of reed bundles on the second layer are the same as those of each row on the first layer, until the last row of the n2th layer is stacked. After the small bundles are tied into bundles, the driver unloads the material. n2 = L3 / 2R (n2 is an integer and decimals are discarded). L3 is the height of the material box. When the reed bundles need to be stacked flat, the three parameters (x 左 、x 右 , y) changes as follows:

[0103] First layer, first row: (L2-k)+x1, x2-(L2-k), yR

[0104] First layer, second row: (L2-k)+x1, x2-(L2-k), y-3R ..........

[0105] The first layer, row n: (L2-k)+x1, x2-(L2-k), y-(2n+1)R

[0106] After the first layer is stacked, the second layer is stacked. The parameters of each row of reed bundles in the second layer are the same as those in the first row. At this time, stacking can be completed by adjusting the displacement of the hydraulic cylinder at the height position of the mechanical clamp. After the nth row of reed bundles in the n2th layer is stacked, the stacking is completed and unloading is completed.

[0107] According to this embodiment, preferably, in order to ensure that the small bundles of reeds stacked vertically into the material box 3 do not fall over, the bottom of the material box 3 can be made into a small groove of a certain height, so that the small bundles of reeds stacked vertically in the material box 3 can be stably stacked. Figure 7 shown.

[0108] like Figure 8-15 As shown, according to this embodiment, preferably, the material box 3 includes a material box shell 302;

[0109] A baling mechanism is provided in the material box shell 302, and the baling mechanism includes a wire clamp and a driving mechanism; the wire clamp is used to clamp the steel wire 314; the driving mechanism drives the wire clamp to tie small bundles of reeds into large bundles.

[0110] In one embodiment of the present invention, the wire clamp includes a first wire clamp 304, a second wire clamp 305, a third wire clamp 306 and a fourth wire clamp 307;

[0111] The first wire clamp 304, the second wire clamp 305, the third wire clamp 306, and the fourth wire clamp 307 are respectively connected to the material box housing 302 through a driving mechanism, and the first wire clamp 304 and the second wire clamp 305 are relatively arranged on one side of the material box housing 302, and the third wire clamp 306 and the fourth wire clamp 307 are relatively arranged on the other side of the material box housing 302;

[0112] The driving mechanism includes a ninth driving mechanism 310, an eleventh driving mechanism 313 and a twelfth driving mechanism 315; one end of the ninth driving mechanism 310 is connected to the twelfth driving mechanism 315 installed on the bottom plate of the material box housing 302, the other end of the ninth driving mechanism 310 is connected to one end of the eleventh driving mechanism 313, and the other end of the eleventh driving mechanism 313 is connected to the wire clamp; the ninth driving mechanism 310 is used to drive the eleventh driving mechanism 313 to move up and down to adjust the height of the wire clamp, and the eleventh driving mechanism 313 is used to drive the wire clamp to move left and right; the twelfth driving mechanism 315 is used to drive the ninth driving mechanism 310 to drive the wire clamp to move forward and backward;

[0113] The ninth driving mechanism 310 and the eleventh driving mechanism 313 are connected to the control unit 7 respectively.

[0114] Fig. 9This is a schematic diagram of the wire clamp movement driving the steel wire to tighten and bind the reed bundle in one embodiment of the present invention. The first wire clamp 304 and the second wire clamp 305 move to loosen the steel wire, and the third wire clamp 306 and the fourth wire clamp 307 move relative to each other to tighten the steel wire. In one embodiment of the present invention, the seventh drive mechanism 308, the eighth drive mechanism 309, the ninth drive mechanism 310, the eleventh drive mechanism 313 and the twelfth drive mechanism 315 are all hydraulic cylinders. Fig.12 As shown, in one embodiment of the present invention, each of the wire clamps comprises another wire clamping block, a shaft, a seventh driving mechanism 308 and an eighth driving mechanism 309;

[0115] The two wire clamping blocks are connected by an axis and arranged in an X shape. The two wire clamping blocks are respectively connected to the seventh driving mechanism 308 and the eighth driving mechanism 309. The seventh driving mechanism 308 and the eighth driving mechanism 309 are connected to the control unit 7; the seventh driving mechanism 308 and the eighth driving mechanism 309 drive the wire clamping blocks to rotate around the axis and adjust the angle between the wire clamping blocks, thereby achieving the clamping or loosening of the steel wire 314.

[0116] In one embodiment of the present invention, the material box 3 further includes a rotating shaft 301 and a tenth driving mechanism 311;

[0117] The rotating shaft 301 is installed on the side of the material box housing 302 close to the material box door 303, and one end is connected to the frame of the harvester through a bearing;

[0118] The eighth driving mechanism 311 is installed on the side of the material box housing 302 far from the material box door 303, and is used to drive the lifting of one side of the material box housing 302, so that the material box housing 302 rotates around the rotating shaft 301, and the material box door 303 of the reed bundles is unloaded;

[0119] The tenth driving mechanism 311 is connected to the control unit 7. Fig.11 As shown, in one embodiment of the present invention, the material box housing 302 is provided with a wire box 312, a displacement sensor, a photoelectric sensor 312-01 and a wire box switch 312-02;

[0120] The wire box 312 is provided with a steel wire 314;

[0121] The displacement sensor is used to detect the rising height of the wire clamp. When the displacement sensor detects that the wire clamp rises to a preset height and transmits a signal to the control unit 7, the control unit 7 controls the wire box switch 312-02 to open the wire box 12, and the steel wire 314 falls from the wire box 12. After the photoelectric sensor 312-01 senses that the steel wire 314 has fallen, it transmits a signal to the control unit 7, and the control unit 7 controls the wire box switch 312-02 to close the wire box 12.

[0122] In one embodiment of the present invention, the movement process of the bundling mechanism is as follows:

[0123] When the small bundles of reeds are arranged in order, the first wire clamp 304, the second wire clamp 305, the third wire clamp 306 and the fourth wire clamp 307 are moved to the position below the wire box 312 under the action of the ninth drive mechanism 310, and the steel wire 314 falls from the wire box 312 and falls into the four wire clamps. Then the seventh drive mechanism 308 and the eighth drive mechanism 309 on both sides of the wire clamps move in opposite directions to clamp the steel wires. After the steel wires are clamped, the ninth drive mechanism 310 moves the steel wire 314 to the middle height position of the large bundle of reeds.

[0124] like Fig.14 As shown: in one embodiment of the present invention, the cutting platform cuts the reeds, the clamping conveyor chain conveys the reeds to the knotter 2, the knotter 2 knots the reeds into small bundles, and the knotted reed small bundles are stacked into the material box 3 by mechanical clamps. When the steel wire 314 is in the middle of the reed bundle, the first wire clamp 304 and the second wire clamp 305 are arranged in height by the first wire clamp 304 and the second wire clamp 305, and the height of the second wire clamp 305 is higher than that of the first wire clamp 304, so that the relative movement can be ensured to tighten the steel wire. Then, the seventh driving mechanism 308 and the eighth driving mechanism 309 on both sides of the third wire clamp 306 and the fourth wire clamp 307 move in the opposite direction to loosen the wire clamps and move downward under the action of the ninth driving mechanism 310. At this time, one side of the steel wire 314 is suspended in the middle of the reed bundle, and the first wire clamp 304 and the second wire clamp 305 on the other side continue to clamp the steel wire 314 to move. Under the action of the eleventh driving mechanism 313, the first wire clamp 304 and the second wire clamp 305 are pushed to move towards each other, so that the steel wire 314 is wrapped around and close to the reed bundle. The left and right ends of the steel wire 314 are staggered, which ensures that the tightened steel wire has sufficient binding force on the reed bundle.

[0125] like Fig.10 As shown: when the bundling of large reed bundles is completed, the four wire clamps are lowered away from the steel wire 314 by the action of the ninth drive mechanism 310. At this time, the material box door 303 is opened, and the left side of the material box 3 is lifted by the action of the tenth drive mechanism 311. The reed bundles fall along the slope in the field under the action of their own gravity. After the fall is completed, the material box 3 returns to its original position for the next bundling work, and the wire clamps clamp the steel wire again. The material box 3 is connected to the reed harvester chassis 6 through the rotating shaft 301.

[0126] After the reed bundle falls, the wire clamp rises to below the wire box 12, the wire box switch 1202 is turned on, and the steel wire falls on the wire clamp. When the photoelectric sensor 1201 on the wire box switch 1202 senses that the steel wire has fallen, the wire box 12 is immediately closed to prevent other steel wires from falling and causing waste. The wire box 12 can be installed on the material box 3 by welding.

[0127] The wire clamp clamps the steel wire 314 through the relative movement of the seventh driving mechanism 308 and the eighth driving mechanism 309 , and releases the steel wire 314 through the opposite movement, and adjusts the displacement in the left and right directions through the eleventh driving mechanism 313 .

[0128] In one embodiment of the present invention, Fig.13 As shown: if the reed bundles are stacked straight, firstly, the arc-shaped steel wire 314 is manually placed into the four steel wire clamps, and then the hydraulic cylinders on both sides of the wire clamps move in the opposite direction to clamp the steel wire 314. After the steel wire 314 is clamped, the steel wire is moved to the bottom of the material box under the movement of the wire clamp lifting hydraulic cylinder. The bottom of the material box has two through grooves that do not interfere with the steel wire moving below the bottom of the material box. The four wire clamps move to both sides, and then the small reed bundles are stacked straight. After the small reed bundles are stacked in sequence, the four wire clamps carry the two steel wires to surround the stacked reed bundles from bottom to top.

[0129] like Fig.14 As shown: when the wire clamp moves to the top of the reed bundle, the first wire clamp 304, the second wire clamp 305, and the two wire clamps are staggered, and the third wire clamp 306 and the fourth wire clamp 307 are staggered. After the staggered arrangement, the first wire clamp 304 and the second wire clamp 305 move toward each other, and the third wire clamp 306 and the fourth wire clamp 307 move toward each other. For example, the first wire clamp 304 is properly raised and then tightened backward, and the second wire clamp 305 is properly lowered and then tightened forward. For example, the reed bundle is tightened by the action of the hydraulic cylinder, and the two steel wires act at the same time, which increases the binding strength of the large reed bundle.

[0130] A control method according to the reed bundling and stacking device comprises the following steps:

[0131] The knotter 2 knots the reeds into small bundles, and the stacking mechanism 4 stacks the small bundles of reeds vertically or horizontally into the material box 3; the material box 3 knots several small bundles of reeds into a large bundle;

[0132] The control unit 7 controls the driving component of the stacking mechanism 4 to drive the first mechanical clamp 401 and the second mechanical clamp 402 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction, so that the first mechanical clamp 401 and the second mechanical clamp 402 can clamp the small bundles of reeds and stack them in the material box 3 in an orderly manner;

[0133] The control unit 7 controls the wire clamp of the bundling mechanism in the material box 3 to clamp the steel wire 314, and the driving mechanism drives the wire clamp to tie the small bundles of reeds into a large bundle.

[0134] In one embodiment of the present invention, when vertical stacking is adopted, the stacking mechanism 4 is controlled by the control unit 7 to stack several small bundles of reeds vertically into the material box 3;

[0135] When the number of small bundles of reeds reaches a preset value, the control unit 7 controls the driving mechanism to drive the wire clamp to rise. When the displacement sensor detects that the wire clamp rises to a preset height and transmits a signal to the control unit 7, the control unit 7 controls the wire box switch 312-02 to open the wire box 12, and the steel wire 314 falls from the wire box 12. After the photoelectric sensor 312-01 senses that the steel wire 314 has fallen, it transmits a signal to the control unit 7, and the control unit 7 controls the wire box switch 312-02 to close the wire box 12.

[0136] The control unit 7 controls the driving mechanism to drive the wire clamp to tie several small bundles of reeds into a large bundle.

[0137] In one embodiment of the present invention, the control unit 7 controls the ninth driving mechanism 310 so that the heights of the relatively arranged first wire clamp 304 and the second wire clamp 305 are inconsistent and the steel wire 314 is clamped; the control unit 7 controls the relatively arranged third wire clamp 306 and the fourth wire clamp 307 to loosen the steel wire 314, while the first wire clamp 304 and the second wire clamp 305 continue to clamp the steel wire 314 and move toward each other, so that the steel wire is wrapped around and pressed against the large bale of reeds to complete the bundling.

[0138] like Fig.14 , 15 As shown, in one embodiment of the present invention, when flat stacking is adopted, the stacking mechanism 4 is controlled by the control unit 7 to stack several small bundles of reeds flatly into the material box 3;

[0139] When the number of small bundles of reeds reaches a preset value, the control unit 7 controls the ninth driving mechanism 310 to drive the wire clamp to rise to a preset position, the first wire clamp 304 and the second wire clamp 305 are connected to the same steel wire 314, and the third wire clamp 306 and the fourth wire clamp 307 are connected to the same steel wire 314;

[0140] The first wire clamp 304 and the second wire clamp 305 are arranged in a staggered manner in the Y-axis direction, and the third wire clamp 306 and the fourth wire clamp 307 are arranged in a staggered manner in the Y-axis direction. The first wire clamp 304 and the second wire clamp 305 move toward each other, and the third wire clamp 306 and the fourth wire clamp 307 move toward each other. The reed bundle is tightened by the steel wire 314, and the two steel wires 314 act at the same time, thereby increasing the binding strength of the large reed bundle. Fig.15 (a); then, under the action of the twelfth driving mechanism 315, the first clamp 304 and the second clamp 305 move in opposite directions in the Y-axis direction, and the third clamp 306 and the fourth clamp 307 move in opposite directions in the Y-axis direction, as shown in FIG. Fig.15As shown in (b), finally, under the action of the eleventh driving mechanism 313, the first wire clamp 304 and the second wire clamp 305 move in opposite directions in the X-axis direction to form a loop, and the third wire clamp 306 and the fourth wire clamp 307 move in opposite directions in the X-axis direction to form a loop, completing the knotting of the reed bundle, as shown in FIG. Fig.15 (c) As shown in the figure, the present invention uses two mechanical clamps to replace manual delivery of reed bundles. The right position adjustment hydraulic cylinder moves to control the distance between the two mechanical clamps to ensure that the reed bundle is clamped. The reverse direction movement is adjusted to adjust the mechanical clamp to clamp the reed bundle and put it into the material box in the y direction. Then, the right position adjustment hydraulic cylinder moves in the same direction to adjust the position of the mechanical clamp to clamp the reed bundle and put it into the material box in the x direction.

[0141] The present invention controls the displacement of the hydraulic cylinder to accurately stack the reed bundles vertically in the grain box, reasonably utilizes the grain box space, improves the harvesting efficiency, and realizes the process of the reed bundles from vertical to horizontal through the rotation of the hydraulic motor, so that it is suitable for stacking in different types of material boxes.
