Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural machinery. BACKGROUND

[0002] Soybean is one of the important food crops in China. China is the largest soybean consumer in the world, with annual consumption of more than 100 million tons, and a production and demand gap of more than 90 million tons. In the past, 65-row soybeans had a large row spacing, and before the soybean rows were closed, due to the large spacing between the soybean rows and the small spacing between the seedlings, a large part of the light was not shining on the leaves but on the ground between the rows for a long period of time during the growth period, especially in the early growth period of soybeans, and the light energy utilization efficiency was low. After the rows were closed, due to the high density of the seedlings, the soybean leaves competed for light (phototropism of plants), and the soybean plants grew upward and were prone to lodging and yield reduction. Therefore, it is of positive significance to find a scientific and effective planting method to improve the yield of soybeans in Northeast China. SUMMARY

The six-rib terminal transmission shaft 1306 and the six-rib terminal transmission shaft support 1310 can be connected through a bearing, so that the six-rib terminal transmission shaft 1306 can rotate relative to the six-rib terminal transmission shaft support 1310, and the chain tensioning auxiliary wheel 1311 is used for assisting to adjust the tightness of the chain between the six-rib terminal transmission shaft input end gear 1309 and the six-rib terminal transmission shaft output end gear 1312.

[0079] See Figure 8 , the output transmission shaft 131302 of the right side gearbox 1308 is fixedly installed with a fertilizer tank power input gear 1314, the fertilizer tank power input gear 1314 is connected with a fertilizer tank power output gear 1206 through a chain, a chain tensioning auxiliary wheel 1207 is arranged between the fertilizer tank power input gear 1314 and the fertilizer tank power output gear 1206, and a wheel frame of the chain tensioning auxiliary wheel 1207 is installed on the fertilizer tank base 1204; the six-rib gearbox transmission shaft 1307 inputs power into the right side gearbox 1308, then conducts to the output transmission shaft 131302 and the fertilizer tank power input gear 1314, finally conducts to the fertilizer tank power output gear 1206 connected through a chain, and the chain tensioning auxiliary wheel 1207 has the same function as the tensioning auxiliary wheel 1311, and is used for assisting to adjust the tightness of the chain between the fertilizer tank power input gear 1314 and the fertilizer tank power output gear 1206.

The big bracket 1316 and the big bracket seat 1318 are connected in the form of a shaft, that is, when the big bracket 1316 rotates, the big bracket seat 1318 will not rotate, so that when the big bracket 1316 rotates, the big bracket seat 1318 and the main beam 1304 fixedly connected thereto will not move. The hydraulic cylinder 1320 functions as a buffer, that is, when the angle between the angle beam 1302 and the ground wheel mechanism 2 changes, it will not change rigidly, but will change slowly according to the hydraulic pressure of the hydraulic cylinder 1320, thereby protecting the equipment.

The large fertilizer tank 1211 is a tank for containing fertilizer. Many agricultural machines have a large fertilizer tank, and there is a mechanism at the bottom of the large fertilizer tank for adjusting the fertilizer output through an adjusting knob. However, the present application designs a new power transmission, so a power transmission rod (fertilizer tank power shifting transmission shaft 1205) with a six-sided cross section is designed to match the power transmission mechanism of the present application. The power of the power transmission rod is transmitted through the chain connection between the fertilizer tank power output gear 1206 and the fertilizer tank power input gear 1314. That is, the six-sided transmission shaft 1307 of the transmission box transmits power to the right transmission box 1308 (from the Figure 5 The direction is to install the transmission box on the main beam 1304), the right transmission box 1308 transmits power to the fertilizer tank power output gear 1206 through the output transmission shaft 131302 and the fertilizer tank power input gear 1314 on the output transmission shaft 131302, and then drives the shifting blade in the shifting bin 1201 to rotate, which completes the shifting of the fertilizer (the function of the shifting blade is the same as that of the existing shifting blade. Since the fertilizer is a solid wet material, it is basically impossible to rely on self-descending, so a shifting function is needed to shift and extrude the fertilizer). The fertilizer amount adjusting knob 1202 also has the same function as the existing adjusting mechanism. The chain tensioning auxiliary wheel 1207 is an auxiliary function. Due to the particularity of the chain connection, an auxiliary wheel for tensioning the chain is needed in the existing technology. The auxiliary wheel of the present application also has the same function.

[0082] The force adding mechanism fixing frame 1102 is installed on the bracket mechanism connecting plate 707, the bracket mechanism connecting plate 707 is installed on the single body mounting frame 1305 through the transverse position adjusting slot 1316, and the two sides of the power mechanism are respectively supported on the two sides of the four-bar linkage mechanism; this mechanism is prior art (patent number: CN201620958971.1), and the four-bar linkage is used for mounting the front frame and the rear frame. The application also has the same effect, and the force adding mechanism and the four-bar linkage are used for connecting the front frame 13 and the bracket mechanism 7.

[0083] The four-bar linkage front end (here, the front end of the cross beam 708) is connected with the bracket mechanism connecting plate 707, the four-bar linkage rear end (here, the rear end of the cross beam 708) is connected with the front end of the bracket mechanism support 701, the force adding mechanism front end is installed on the bracket mechanism connecting plate 707, the force adding mechanism rear end two sides are pressed on the bracket mechanism connecting plate 707, and the bracket mechanism connecting plate 707 is installed on the main beam 1304 rear side single body mounting frame 1305 through bolts. The transverse adjusting slot opened on the single body mounting frame 1305 is used for adjusting the transverse position of the rear single body (referring to the bracket mechanism 7 connected through the four-bar linkage). Since general equipment will be installed with multiple single bodies (three sets of single bodies are shown in the application), in order to avoid installation problems, the transverse adjusting slot is arranged.

[0084] The power wheel mechanism 10: the power wheel mechanism mounting seat 1010 is installed on the main beam 1304, one end of the power wheel mechanism support 1003 is installed on the two sides of the power wheel mechanism mounting seat 1010 through the power wheel mechanism shaft 1012, the front end of the power wheel mechanism support 1003, the power wheel mechanism mounting seat 1010 and the power wheel mechanism shaft 1012 have a large diameter through hole 1011, the six-sided gearbox transmission shaft 1307 passes through the large diameter through hole 1011 and is installed with a power output gear 1001 on one side, the large diameter through hole 1011 is sleeved on the outside of the six-sided gearbox transmission shaft 1307 but does not contact the six-sided gearbox transmission shaft 1307, the power output gear 1001 is connected with a power input gear 1006 through a chain, the power input gear 1006 is installed on a power input shaft 1009, the power input shaft 1009 is installed on the power wheel mechanism support 1003 through bearings on both ends, a power input wheel 1008 is installed on the power input shaft 1009, the power input wheel 1008 corresponds to the upper surface of the ground wheel 1319 on one side, left and right auxiliary gears 1005 and 1007 are respectively installed on the power wheel mechanism support 1003 on the two sides of the power input gear 1006; a power wheel mechanism booster spring 1004 is installed on the power wheel mechanism support 1003 on the upper end and is installed on the main beam 1304 on the other end.

[0085] The power mechanism 10 is the main source of power for the large fertilizer box mechanism, the mouth fertilizer mechanism, the seed box mechanism and the like of the application. Figure 15 andFigure 16 From Figure 2 And Figure 3 It can be seen that the power mechanism corresponds to the ground wheel mechanism 2 above, the input of power is through the contact of the power input wheel 1008 with the ground wheel 1319 of the ground wheel mechanism 2, and then the rotation of the ground wheel 1319 drives the power input wheel 1008 to rotate, and the power input wheel 1008 also rotates with its wheel shaft (power input shaft 1009), so that the power input gear 1006 installed on the side of the wheel shaft also rotates, and the power input gear 1006 drives the power output gear 1001 to rotate through the chain, and since the power output gear 1001 is fixedly installed on the six-ribbed gearbox transmission shaft 1307, the rotation is also transmitted to the six-ribbed gearbox transmission shaft 1307.

[0086] The power wheel mechanism mounting seat 1010 has mounting ears 1002 on both sides, and the power wheel mechanism mounting seat 1010 is fixedly installed on the main beam 1304 through the mounting ears 1002 by bolts, and the power wheel mechanism support 1003 is connected with the power wheel mechanism mounting seat 1010 through the power wheel mechanism shaft 1012, so that the power wheel mechanism support 1003 and the power wheel mechanism mounting seat 1010 will not move together, that is, the power wheel mechanism mounting seat 1010 can move with the main beam 1304, but the power wheel mechanism support 1003 will not move.

[0087] Due to the positional relationship, the six-ribbed gearbox transmission shaft 1307 must pass through the power mechanism 10 close to one end of the main beam 1304, so the power wheel mechanism support 1003, the power wheel mechanism shaft 1012 and the power wheel mechanism mounting seat 1010 are provided with a gap hole (large diameter through hole 1011), and the six-ribbed gearbox transmission shaft 1307 passes through the hole, but cannot contact the hole wall.

[0088] The working relationship between the power mechanism 10 and the ground wheel mechanism 2: the fixed relationship between the adjusting angle beam 1302 and the main beam 1304, the tail end shaft of the cylinder body of the hydraulic cylinder 1320 is installed on the adjusting angle beam 1302, the piston rod shaft of the hydraulic cylinder 1320 is installed at one end of the hydraulic mechanism support 1315, the other end of the hydraulic mechanism support 1315 is fixedly installed on the big bracket 1316, the hydraulic mechanism support 1315, the hydraulic cylinder 1320, and the adjusting angle beam 1302 are installed in a triangular shape, the ground wheel mechanism 2 is fixedly connected with the big bracket 1316, and the main beam 1304 is connected with the big bracket 1316 in a shaft form (it means that when the big bracket 1316 rotates, the main beam 1304 will not rotate), so that the power mechanism 10 installed on the main beam 1304 will not rotate. When the ground wheel 1319 of the ground wheel mechanism 2 contacts the ground, it will be slowly lifted upwards under the action of the pressure above, and at the same time, the big bracket 1316 and the hydraulic mechanism support 1315 will rotate clockwise, and at this time, the power mechanism 10 is in a relatively static state relative to the ground wheel mechanism 2, until the ground wheel 1319 contacts the power input wheel 1008. In this way, in the process of moving, the rotation of the ground wheel will drive the power input wheel 1008 to rotate, thereby transmitting power to the six-rib transmission shaft 1307 of the gear box.

[0089] Here, since the power wheel mechanism support 1003 and the power wheel mechanism mounting seat 1010 are connected in a shaft form, the power wheel mechanism support 1003 and the mechanism above it are hung in the form of self gravity (when there is no bottom support or any support contact, the bottom of the power wheel mechanism support 1003 is placed on the main beam 1304), when the ground wheel 1319 contacts the power input wheel 1008, it is extremely likely to be out of contact, at this time, the power input wheel 1008 is forced to maintain contact with the ground wheel 1319 through the elastic force of the power wheel mechanism booster spring 1004.

[0090] A transmission structure of a seed box and a fertilizer box: this part is shown in Figures 23-27 The transmission mechanism includes a power input part, a seed box seeding transmission part, and a fertilizer box fertilizer transmission part. The transmission mechanism is installed on the four-bar linkage structure and the bracket mechanism 7 in sequence, and the power source is the six-rib terminal transmission shaft 1306 of the no-tillage seeder plant spacing adjustment gear box (left gear box 1313) installed on the main beam 1304.

[0091] The seed box and the fertilizer box power input mechanism 706 is installed on the side beam 708 of the four-bar linkage mechanism, the seed box power input mechanism 704 is installed on the corresponding seed box under the bracket 701 of the bracket mechanism, the seed box chain tensioning mechanism 705 is installed on the bracket mechanism bracket 701 between the seed box power input mechanism 704 and the seed box and the fertilizer box power input mechanism 706, the fertilizer box power input mechanism 702 is installed on the corresponding fertilizer box under the bracket mechanism bracket 701, and the fertilizer box chain tensioning mechanism 710 is installed on the bracket mechanism bracket 701 between the fertilizer box power input mechanism 702 and the seed box and the fertilizer box power input mechanism 706. The four-bar linkage mechanism is also used to connect the main beam 1304 and the bracket mechanism 7, and the four-bar linkage mechanism is composed of the bracket mechanism connecting plate 707 and the two side beams 708. Figure 23 And Figure 24 It can be seen that the beam 708 has four beams in total, forming a cubic shape, and the left and right side beams 708 are installed on the bracket mechanism connecting plate 707 and the bracket mechanism 7 in the form of a shaft, so that the beam 708 rotates around the shaft. In addition, since the bracket mechanism connecting plate 707 is fixed on the main beam 1304, the bracket mechanism 7 has a space for up and down movement relative to the front frame 13.

[0092] The seed box and the fertilizer box power input mechanism 706: a power transmission No. 1 gear 709 is installed on the six-rib terminal transmission shaft 1306, and the six-rib terminal transmission shaft 1306 is connected to the side beam 708 of the four-bar linkage mechanism through a bearing.

[0093] The structure of the seed box and the fertilizer box is a relatively mature technology, the seed box is shown in Figure 17 And Figure 18 The structure of the fertilizer box is shown in Figure 19 In order to facilitate the seed or fertilizer in the box to be moved, a moving mechanism (a seeding wheel 905 on the seed box and a fertilizer moving wheel 802 on the fertilizer box) is installed on the upper end of the seeding pipe or the fertilizer pipe at the bottom of the box body. In order to cooperate with the two moving mechanisms, the transmission mechanism (the seed box and the fertilizer box power input mechanism 706) for driving the two moving mechanisms to work normally is arranged on the bracket mechanism 7, and the transmission mechanism transmits the power of the six-rib terminal transmission shaft 1306 to the seed box power input mechanism 704 and the fertilizer box power input mechanism 702 in sequence.

[0094] The seed box power input mechanism 704 is shown in Figure 26The power transmission gear 709 is connected with the seed box mechanism large gear 70403 through a chain, the seed box mechanism large gear 70403 is installed on the seed box mechanism shaft 70407, the seed box mechanism shaft 70407 is sleeved with a bearing at the part penetrating through the bracket mechanism support 701, the outer tile of the bearing is fixedly connected with the bearing sleeve 70408, the bearing sleeve 70408 is fixedly installed on the bracket mechanism support 701, that is, the inner tile of the bearing is connected with the seed box mechanism shaft 70407, the outer tile of the bearing is fixedly connected with the bracket mechanism support 701 through the bearing sleeve 70408; the seed box mechanism shaft 70407 is hollow, a seed box mechanism inner shaft is inserted in the hollow, one end of the seed box mechanism inner shaft is installed with the manual adjusting knob 70406, the other end is the seed box contact head 70401, the seed wheel engagement groove 70410 is formed in the front end of the seed box contact head 70401, the adjusting spring 70402 is sleeved in the middle part of the seed box mechanism inner shaft, one end of the adjusting spring 70402 is clamped on the inner wall clamping table of the hollow of the seed box mechanism shaft 70407, the other end is clamped on the rear end of the seed box contact head 70401; the longitudinal clamping groove 70409 is formed in the side of the seed box mechanism shaft 70407 close to the manual adjusting knob 70406, the locking pin 70405 is arranged on the seed box mechanism inner shaft corresponding to the side of the longitudinal clamping groove 70409.

[0095] The detailed structure and connection relationship of the seed box power input mechanism 704 are shown in Figure 26 , Figure 26 The seed box power input mechanism 704 and the seed box chain tensioning mechanism 705 are both installed on the same side plate of the bracket mechanism support 701.

[0096] The seed box mechanism shaft 70407 is a hollow tube which is mounted on the bracket mechanism support 701 through bearings. In order to protect the bearings, a bearing sleeve 70408 is added, which is buckled on the bearings and fixedly connected with the outer tile of the bearings. The bearing sleeve 70408 is fixedly installed on the bracket mechanism support 701, so that the seed box mechanism shaft 70407 can rotate relative to the bearing sleeve 70408 and the bracket mechanism support 701. A seed box mechanism inner shaft is inserted in the hollow seed box mechanism shaft 70407. One end of the seed box mechanism inner shaft is provided with a manual adjusting knob 70406, and the other end is provided with a seed box contact head 70401 which is integrated. The outer diameter of the seed box contact head 70401 is larger than the outer diameter of the seed box mechanism inner shaft. As can be seen from the figure, the manual adjusting knob 70406 is outside the bracket mechanism support 701, and the seed box contact head 70401 is inside the bracket mechanism support 701. Therefore, personnel can adjust the seed box mechanism inner shaft and the seed box contact head 70401 by plugging or rotating the manual adjusting knob 70406 outside. A spring (adjusting spring 70402) is sleeved outside the seed box mechanism inner shaft and inside the seed box mechanism shaft 70407. In order to facilitate the installation of the spring, a clamping table is arranged on the inner wall of the seed box mechanism shaft 70407. Therefore, the two ends of the spring are clamped between the clamping table and the seed box contact head 70401, Figure 26 In order to adjust the length of the seed box contact head 70401 engaged with the seeding wheel 905 of the seed box, when it is needed to disengage the seed box contact head 70401 from the seeding wheel 905, the seed box mechanism inner shaft is pulled out by holding the manual adjusting knob 70406 with hand. At this time, not only the seed box contact head 70401 is disengaged from the seeding wheel 905 of the seed box, but also the locking pin 70405 is disengaged from the longitudinal clamping groove 70409, and the adjusting spring 70402 is compressed. Then, the manual adjusting knob 70406 is rotated by about 90 degrees until the locking pin 70405 is clamped on the outer edge of the seed box mechanism shaft 70407. Thus, the disengagement is completed. Conversely, when the locking pin 70405 corresponds to the position of the longitudinal clamping groove 70409, under the rebounding action of the spring, the locking pin 70405 enters the inside of the longitudinal clamping groove 70409 Figure 26 position), and the seed box contact head 70401 is engaged with the seeding wheel 905 of the seed box. The seed wheel engagement groove 70410 is a horizontal groove which corresponds to the pin rod on the seeding wheel 905 of the seed box. When the seed box contact head 70401 is engaged with the seeding wheel 905 of the seed box, the pin rod on the seeding wheel 905 of the seed box is clamped in the seed wheel engagement groove 70410.

[0097] The two gears (the seed box mechanism large gear 70403 and the mouth fertilizer box input gear 70404) are installed on the seed box mechanism shaft 70407 at the same time, and the two gears will rotate at the same time under the driving of the chain, so that when the seed box contact head 70401 is engaged with the seeding wheel 905 of the seed box, the power is transmitted to the seeding wheel 905, and the seed is moved.

[0098] The seed box chain tensioning mechanism 705 is installed on the bracket mechanism support 701, and is placed between the seed box and the mouth fertilizer box power input mechanism 706 and the seed box power input mechanism 704 and connected with the chain. The mechanism maintains the tight state of the transmission belt or chain, so as to ensure the efficient operation of the transmission system.

[0099] From Figure 26 From the right side, the seed box chain tensioning mechanism 705 adopts double-wheel tensioning wheels (the basic tensioning wheel 70504 and the auxiliary tensioning wheel 70505), and the two tensioning wheels are connected in parallel on the tensioning wheel support 70506. That is to say, the two tensioning wheels can rotate independently relative to the tensioning wheel support 70506, so that the chain is in the form of rolling friction when passing through. The tensioning wheel support 70506 has a fixedly connected support shaft 70501 on the side, the support shaft 70501 is inserted into the support shaft sleeve 70502 in the form of shaft through the support shaft seat 70507, the support shaft sleeve 70502 is fixed on the bracket mechanism support 701, the support shaft 70501 passes through the outer end of the tensioning wheel support 70506 and is limited by the support limiting bolt 70508, the tensioning spring 70503 is sleeved on the support shaft seat 70507, the tail end of the tensioning spring 70503 is fixed on the support shaft seat 70507, and the other end is hooked on the outer edge of the tensioning wheel support 70506. Figure 26 From the direction of the illustration, the chain from the seed box and the mouth fertilizer box power input mechanism 706 (the gear power transmission No. 1 gear 709 of this mechanism) passes through the bottom of the basic tensioning wheel 70504 to the space between the basic tensioning wheel 70504 and the auxiliary tensioning wheel 70505, and then passes through the upper part of the auxiliary tensioning wheel 70505 and is connected with the seed box mechanism large gear 70403. In this way, the chain between the gear power transmission No. 1 gear 709 and the seed box mechanism large gear 70403 is tensioned.

[0100] The mouth fertilizer box power input mechanism 702: the mouth fertilizer box input gear 70404 coaxial with the mouth fertilizer box mechanism gear 70403 is installed on the seed box mechanism shaft 70407, the mouth fertilizer box input gear 70404 is connected with the mouth fertilizer box output gear 70202 through a chain, the mouth fertilizer box output gear 70202 is installed on the mouth fertilizer box mechanism shaft 70206, the mouth fertilizer box mechanism shaft 70206 is sleeved with a bearing through the bracket mechanism support 701, the outer tile of the bearing is fixedly connected with the mouth fertilizer box shaft bearing sleeve 70204, and the mouth fertilizer box shaft bearing sleeve 70204 is fixed on the bracket mechanism support 701; the mouth fertilizer box mechanism shaft 70206 is hollow, the mouth fertilizer box manual adjusting rod 70209 with the mouth fertilizer box manual adjusting knob 70201 at one end is inserted into the hollow, the other end of the mouth fertilizer box manual adjusting rod 70209 is the mouth fertilizer box contact head 70207, the front end of the mouth fertilizer box contact head 70207 is provided with a mouth fertilizer wheel occlusion groove 70208, the adjusting reset spring 70205 is sleeved on the mouth fertilizer box manual adjusting rod 70209, one end of the adjusting reset spring 70205 is clamped on the inner wall clamping table of the mouth fertilizer box mechanism shaft 70206, and the other end is clamped on the rear end of the mouth fertilizer box contact head 70207; the mouth fertilizer mechanism extension sliding groove 70210 is formed on the side of the mouth fertilizer box mechanism shaft 70206 close to the mouth fertilizer box manual adjusting knob 70201, and the mouth fertilizer box mechanism locking pin 70203 is arranged on the mouth fertilizer box manual adjusting rod 70209 corresponding to the side of the mouth fertilizer mechanism extension sliding groove 70210.

[0101] The structure of the mouth fertilizer box power input mechanism 702 is basically the same as that of the seed box power input mechanism 704, as shown in Figure 25 The power is transmitted through the connection of the mouth fertilizer box output gear 70202 and the mouth fertilizer box input gear 70404 through a chain. The mouth fertilizer wheel occlusion groove 70208 on the mouth fertilizer box contact head 70207 can be connected to the mouth fertilizer wheel 802. The connecting chain between the mouth fertilizer box output gear 70202 and the mouth fertilizer box input gear 70404 is also provided with a chain tensioning mechanism 710, and the structure and connection mode of the mechanism are the same as those of the seed box chain tensioning mechanism 705.

[0102] The roller mechanism: the roller support 602 is installed on the rear side of the seeding unit mechanism support 501 through the bolt shaft 601, the fixed hanger 607 is arranged at the bottom of the seeding unit mechanism support 501, one end of the roller mechanism spring 605 is hung on the fixed hanger 607, the other end is hung on the middle part of the roller mechanism adjusting rod 604, the low-end shaft of the roller mechanism adjusting rod 604 is connected with the roller connecting rod 606, the roller connecting rod 606 is fixed on the roller support 602, the roller mechanism adjusting rod 604 is arranged in the adjusting rod position groove 608 formed on the upper surface of the roller support 602.

[0103] The roller mechanism is shown in Figure 20 , Figure 21 andFigure 22 , the pressing roller mechanism is installed behind the seeding unit mechanism 5 (see Figure 28 , the connection relationship between the pressing roller mechanism, the seeding unit mechanism 5 and the bracket mechanism 7). The pressing roller bracket 602 is both the support frame of the entire mechanism and used to connect to the seeding unit mechanism 5 (the rear end of the upper seeding unit bracket 501 on the seeding unit mechanism 5). The pressing roller bracket 602 can rotate around the bolt shaft 601 relative to the seeding unit bracket 501. The settings of the pressing roller mechanism adjusting rod 604, the pressing roller mechanism spring 605 and the fixed hanger 607 are to adjust the gravity of the pressing roller pressing on the ground. See Figure 21 , the adjusting rod position groove 608 is opened on the upper surface of the pressing roller bracket 602 and is composed of a longitudinal groove and multiple transverse grooves. The longitudinal groove and the transverse grooves look similar to the character "丰" (abundant). In the longitudinal groove, the pressing roller mechanism adjusting rod 604 can move back and forth to increase the elastic force of the pressing roller mechanism spring 605. Through this elastic force, the pressing gravity exerted on the pressing roller 603 by the entire pressing roller mechanism is increased. The transverse grooves are used to lock the pressing roller mechanism adjusting rod 604 in the adjusted position to prevent it from rebounding due to the elastic force of the pressing roller mechanism spring 605. The bottom of the pressing roller mechanism adjusting rod 604 is a ring that is sleeved on the pressing roller connecting rod 606 and can rotate freely. In this way, a relative adjustment fulcrum will be formed at the bottom of the pressing roller mechanism adjusting rod 604. In this way, when the pressing roller mechanism adjusting rod 604 is moved back and forth, the spring will be pulled to stretch and contract simultaneously. Through this structure, it can be seen that the pressing roller mechanism can rotate relative to the seeding unit mechanism 5, but the applied pressing force is completed by relying on two forces. The first is the gravity generated by the weight of this application, and the second is the gravity applied through the elastic force of the spring.

[0104] Seed box mechanism 9: See Figure 17 and Figure 18 , in front of the lower end of the seed box 901, there is a seed box hook 902 that matches the bracket mechanism bracket 701. The rear side of the lower end of the seed box 901 is installed on the bracket mechanism bracket 701 through the seed box mounting frame 904. The seeding wheel 905 at the seed discharging mechanism 903 at the lower end of the seed box mechanism 9 is correspondingly clamped with the seed box contact head 70401; this part is not particularly crucial and is to add some installation stability mechanisms to cooperate with the structure of the bracket mechanism bracket 701 of the present invention. The seed box hook 902 and the seed box mounting frame 904 are both mounting frames designed for the corresponding positions on the bracket mechanism bracket 701.

[0105] Fertilizer box mechanism 8: See Figure 19 , the fertilizer box 801 is installed on the bracket mechanism bracket 701 through the fertilizer box mounting bracket 803 at the bottom end, and the fertilizer box contact head 70207 is docked on the fertilizer distributing wheel 802; the setting of the fertilizer box mounting bracket 803 is also to facilitate the installation of the fertilizer box on the bracket mechanism bracket 701.

The disc knife mechanism, the bionic wheel mechanism, and the auxiliary mechanism are installed below the sowing monomer mechanism total support 503.

[0107] Disc knife mechanism: the lower end of the front end of the sowing monomer mechanism total support 503 is an inwardly inclined inclined support 520, a disc knife hole 506 is opened in the middle of the inclined support 520, and the disc knife shaft 517 of the disc knife 515 is installed on the disc knife bearing frame on the side of the inclined support 520 through the disc knife bearing 516. The disc knife bearing frame is a bearing seat on the side of the inclined support 520 for convenient installation of the bearing, and it is fixed with the outer tile of the bearing. In this way, the disc knife can rotate.

[0110] The soil scraping knife 508 is installed on the lower end of the sowing monomer mechanism total support 503 through the support; the seed tube 505 leans on the side of the disc knife 515, and the seed discharge port below the seed discharge mechanism 903 is communicated with the seed tube 505 through the seed discharge hose.

[0111] The sowing monomer mechanism total support 503 is the support frame of the entire mechanism, which is installed on the bracket mechanism support 701 through two parts, the upper end is fixedly installed on the bracket mechanism support 701 through the sowing monomer mechanism upper support 703, and the front end is directly installed on the bottom of the front end of the bracket mechanism support 701 (see Figure 28 In order to clearly show the connection relationship between the various components, the press wheel 603, the bionic wheel 4, and the seed disc 515 are disassembled in this figure). The inclined support 520 is integrated with the sowing monomer mechanism total support 503, which is located in front of the sowing monomer mechanism total support 503. In order to facilitate the installation of the disc knife, the top end is just installed on the bottom of the front end of the bracket mechanism support 701.

[0112] On the main support 503 of the seeding monomer mechanism, it is necessary to install the bionic wheel 4 (generally two are needed, and the two wheels are coaxially installed) and its mechanism, the disc cutter 515 and its mechanism, and some auxiliary mechanisms.

[0113] The bionic wheel 4 and its mechanism have two parts. One part is the part for mounting the bionic wheel, and the other part is the part for restricting the bionic wheel. See Figure 28 , The bionic wheel 4 is installed at the bottom of the wheel frame 509 through an axle, axle seat, and bearing (there is an axle hole 507 at the bottom of the wheel frame 509, and the axle of the bionic wheel 4 is inserted into this hole, and the axle of the bionic wheel 4 is then connected to this hole through a bearing). The bionic wheel 4 can roll at the bottom of the wheel frame 509, and the bionic wheel 4 contacts the ground.

[0114] The upper end of the wheel frame 509 is installed on the wheel frame mounting seat 519 in the form of an axle, and the upper end of the wheel frame 509 can rotate around this axle. Since the bionic wheel 4 is installed at the lower end of the wheel frame 509., relying on the natural drooping of the bionic wheel 4's own weight to contact the ground. When the ground is uneven, it may cause the bionic wheel 4 and the wheel frame 509 to bounce upward and not achieve the effect. Therefore, an upper limit mechanism (auxiliary mechanism: the wheel frame 509 positioning mechanism) is set on the wheel frame 509. See Figure 29 , Looking from above, the gear slot 513 is similar to the character "丰" ( Figure 30 ), with multiple horizontal groove positioning slots and a vertical groove shifting slot. The gear lever 502 can be moved back and forth by hand in the vertical groove shifting slot, thereby changing the distance between the bottom end of the positioning pressure block 511 and the upper surface of the wheel frame 509, thus limiting the upward movement of the wheel frame 509 and trying to keep the bionic wheel 4 in contact with the ground.

[0115] The auxiliary mechanism part also includes a set scraper blade, seed discharging pipe, etc. The scraper blade is attached to the side of the disc cutter 515 in a sheet shape for scraping the soil adhered to its surface. The seed discharging pipe has its upper end installed on the main support 503 of the seeding monomer mechanism, and generally follows the shape of the inner side of the inclined support 520, and is also close to the side of the disc cutter. The seed discharging port below the seeding mechanism 903 is inserted into the seed discharging pipe 505 from above through a seed discharging hose. In this way, the seeds coming from the seed box enter the seed discharging pipe 505 and are applied to the ground from the bottom end. There is a mud scraping plate 504 corresponding to the outer edge of the bionic wheel 4, and the upper end of the mud scraping plate 504 is installed on the main support 503 of the seeding monomer mechanism.

[0116] See Figure 30 , There is a topdressing application port 518 on the main support 503 of the seeding monomer mechanism. The topdressing box seed discharging pipe 804 is inserted into the topdressing application port 518; topdressing is applied through this port.

[0117] The grass separating mechanism 3 is installed at the front end of the seeding unit mechanism total bracket 503 through the grass separating mechanism seat 301. The grass separating wheel frame 302 is installed on the grass separating mechanism seat 301 through the grass separating wheel frame bolt shaft 311. The front end of the grass separating wheel frame 302 is inwardly bent, and the grass separating wheel 303 is installed on the bent part through the wheel shaft. The corrugated knife frame 305 is installed at the bottom end of the grass separating mechanism seat 301, and the middle part is fixed with the grass separating wheel frame 302 through the bolt. The corrugated knife shaft 308 is installed on the upper end of the corrugated knife frame 305. The corrugated knife shaft sleeve 313 is installed on the corrugated knife shaft 308 through two groups of knife shaft tapered bearings 307. The oil cavity 310 is left between the two groups of knife shaft tapered bearings 307. The oil injection channel 309 is opened in the corrugated knife shaft 308. One end of the oil injection channel 309 is communicated with the oil cavity 310, and the other end is communicated with the outside from the side of the corrugated knife shaft 308, and the oil injection nozzle 312 is installed. The oil injection nozzle 312 is communicated with the oil injection system through the connecting pipe. The sealing cap 306 is installed at the outer end of the corrugated knife shaft 308. The edge of the sealing cap 306 and the corrugated knife 304 are fastened on the corrugated knife frame 305 through the bolt.

[0118] See Figure 1 The grass separating mechanism 3 is installed in front of the seeding unit mechanism 5. The grass separating mechanism 3 and the seeding unit mechanism 5 are installed through the connection of the grass separating mechanism seat 301 and the seeding unit mechanism total bracket 503. Figure 33 It can be seen that the grass separating wheel 303 (two) and the corrugated knife 304 (one) need to be installed on the grass separating mechanism 3. The two grass separating wheels 303 are arranged in an inward eight-shaped form (which can be understood as the front end of the grass separating wheel frame 302 being inwardly bent) in order to achieve the grass separating effect. The corrugated knife 304 is located between the two grass separating wheels 303. The two grass separating wheels 303 are respectively installed at the front end of the grass separating wheel frames 302 on both sides. The bottom frame cross beams of the grass separating wheel frames 302 on both sides are fixedly connected, and the grass separating wheel frame bolt shaft 311 is fixed on the grass separating mechanism seat 301 through the frame cross beam.

[0119] Since the corrugated knife 304 is approximately located at the central position between the grass separating wheel frames 302 on both sides, the support (corrugated knife seat 305) for suspending the corrugated knife 304 is a side support (see Figure 33 The corrugated knife seat 305 is fixed on the grass separating mechanism seat 301 and the grass separating wheel frame 302 on one side through two groups of bolts. The corrugated knife shaft 308 is installed on the corrugated knife seat 305, and the corrugated knife 304 is installed on the corrugated knife shaft 308 through the corrugated knife shaft sleeve 313 and the knife shaft tapered bearings 307 (two groups).

[0120] Because the corrugated knife 304 is the corrugated knife sleeve 313, the knife shaft taper bearing 307 (two groups) is installed on the corrugated knife shaft 308, and it is between the two sides of the grass separating wheel frame 302, in order to keep the bearing lubrication rolling, and can not make the foreign matter into the bearing working cavity (that is, the cavity formed between the corrugated knife sleeve 313 and the corrugated knife shaft 308, that is, the oil cavity 310), therefore, a lubricating oil closed cavity (including the oil cavity 310) is arranged, see Figure 34 The closed cavity is surrounded by the oil seal cover (seal cap 306), the corrugated knife sleeve 313 and the bearing end baffle 314, the cavity is closed in the bearing (knife shaft taper bearing 307), in order to inject lubricating oil into the cavity, therefore, the oil injection channel 309 is arranged, the oil injection channel 309 is arranged in the corrugated knife shaft 308, one end is communicated with the outside, and the oil injection nozzle 312 is additionally arranged, the other end is communicated with the oil cavity 310, so that the lubricating oil is added into the lubricating oil closed cavity through the oil injection nozzle 312.

[0122] See Figure 2 and Figure 3 The fertilizer applicator mechanism 1 is installed on the fertilizer applicator mechanism mounting frame 1303 of the front frame 13 part, and there are two sets, one on each side of the angle beam 1302 of the front frame 13. The two fertilizer applicator mechanisms 1 are the same in structure, but the positions of the components are corresponding.

[0123] The fertilizer applicator mechanism 1 is fastened to the fertilizer applicator mechanism mounting frame 1303 by the cooperation of the fastening collar 101 and the bolt. The fastening collar 101 is sleeved on the fertilizer applicator mechanism mounting frame 1303, the end of the fastening collar 101 is inserted into the fertilizer fixing frame 102, and the end has a thread. After fastening with a nut, the fastening collar 101 tightly clamps the fertilizer applicator mechanism mounting frame 1303 between the fastening collar 101 and the fertilizer fixing frame 102.

[0124] The fertilizer applicator adjusting frame 103 is inserted into the inside of the fertilizer fixing frame 102. When not fastened by the bolt, the height can be adjusted as needed. When adjusted to the required height, it can be fastened by the bolt.

[0125] Two connecting frame sleeves (spring shaft sleeve 112, horizontal plate shaft sleeve 111) are installed on the fertilizer applicator adjusting frame 103 from bottom to top, respectively used to install one end of the connecting spring assembly (return spring 104 and its connecting assembly) and the connecting plate assembly (horizontal connecting plate 110). The two are connected by bolts (the bolt inserted into the spring shaft sleeve 112 and the horizontal plate bolt shaft 121 inserted into the horizontal plate shaft sleeve 111), and can rotate around the shaft.

[0126] See Figure 35 The other end of the horizontal connecting plate 110 is installed on one end of the disc shaft of the fertilizer cutter head 106 at the same time as the longitudinal connecting plate 108, and the horizontal connecting plate 110 and the longitudinal connecting plate 108 can independently rotate around the disc shaft. In this way, the return spring 104 and its connecting assembly, the horizontal connecting plate 110, the longitudinal connecting plate 108, and the fertilizer applicator adjusting frame 103 form a mechanism similar to a four-bar linkage, and the four corners are connected in the form of a shaft and can rotate.

The telescopic amount between them is limited by the cooperation of the limiting pin 117 and the limiting groove 118. The limiting pin 117 is fixed on the telescopic inner rod 113, and the limiting groove 118 is opened on the telescopic outer rod 114. The limiting pin 117 can only slide in the limiting groove 118.
