Description

Technical Field

[0001] The invention belongs to the technical field of cotton seedling placing, and in particular relates to a cotton seedling placing machine. Background Art

[0002] The main purpose of releasing cotton seedlings is to cultivate strong seedlings and promote the early growth and development of cotton. Release is the first task of cotton seedling management. Timely and scientific release is conducive to the cultivation of strong seedlings and early emergence of seedlings. The principle of releasing seedlings is "releasing green but not yellow", that is, the film is broken and the seedlings are released in time when the cotyledons of cotton turn from yellow to green, avoiding the problem of improper release caused by releasing seedlings too early or too late. In addition, releasing seedlings can also help prevent high temperature scalding of seedlings and the formation of tall seedlings, which is not conducive to the cultivation of strong and straight cotton seedlings.

[0003] Currently, cotton seedlings are mostly released manually. When the cotton seedlings have emerged from the soil by 60%-70%, the cotyledons have flattened and the leaves have turned green, the seedlings should be released in time. In areas where cotton is planted on a large scale, temporary workers are often hired to manually break the soil and release the seedlings to ensure that the seedlings are not affected. The labor costs put farmers under great economic pressure, which is not only time-consuming and labor-intensive, but also has high labor costs.

[0004] When the existing cotton seedling placing equipment is in use, the film breaking hook cannot be adjusted, resulting in a single use environment. Summary of the invention

[0005] The purpose of the invention is to provide a cotton seedling placing machine which can break the membrane of cotton seedlings of different row widths.

[0006] The cotton seedling placing machine comprises a frame, on which two rotating shafts are rotatably mounted and spaced apart from each other and arranged longitudinally. A walking wheel is mounted on the rotating shaft on the left side, and film opening wheels are mounted at both ends of the rotating shaft on the right side. Hook heads are arranged on both sides of the wheel edge of the film opening wheel for inward and outward extension along the wheel center. The positions of the two film opening wheels on the rotating shaft are adjustable, and the rotating shaft on the left side is power-transmitted with the rotating shaft on the right side through a transmission mechanism.

[0007] The walking wheel is located in the aisle between the two rows of ground films. The walking wheel rotates and moves along the aisle, driving the film-opening wheel to rotate through the transmission mechanism, driving the hook head to break the ground film covering the cotton seedlings to release the seedlings; according to the distance between the front and rear rows of ground films, the front and rear position of the film-opening wheel on the rotating shaft is adjusted front and back, and the distance between the two film-opening wheels is adjusted, so that the ground films with different distances can be broken; the hook head that is telescopic along the inner and outer sides of the film-opening wheel can be adjusted to extend the hook head to the outside of the film-opening wheel or retract to the inside of the film-opening wheel. After the hook head is retracted, the film-opening wheel and the walking wheel are used as wheels for easy transfer.

[0008] Furthermore, the film opening wheel is a first film opening mechanism, which includes a first sleeve sleeved on the rotating shaft and having an adjustable position, a first support ring is disposed on the first sleeve, and the first support ring is connected to the first sleeve through a plurality of first keels; A limiting protrusion is fixed on the inner side wall of the first sleeve, and a limiting sliding groove corresponding to the limiting protrusion is provided on the rotating shaft and is slidably matched with the limiting protrusion. A locking threaded hole communicating with the inside and outside is provided on the first sleeve, and a locking screw threadedly matched with the limiting protrusion is installed in the locking threaded hole. When the first sleeve moves along the rotating shaft, the first sleeve is fixed on the rotating shaft by the locking screw. The first film opening assembly is arranged on the front and rear sides of the first keel, and the first film opening assembly includes a fixing sleeve installed on the front and rear sides of the first keel, and the fixing sleeve can move along the first keel toward the inner and outer sides of the first support ring, and a fixing block that can move forward and backward is arranged in the fixing sleeve, and the first film opening hook and the second film opening hook for connecting the hook head are fixed on the fixing block, and one end of the first film opening hook and the second film opening hook are fixed to the fixing block, and the other end is bent and detachably connected to the hook head.

[0009] When the locking screw is actually used, it is screwed inwardly into the limiting slide groove to fix the first shaft sleeve on the rotating shaft; the limiting protrusion fixed in the first shaft sleeve slides back and forth along the limiting slide groove, thereby driving the first support ring to move back and forth, thereby realizing the adjustment of the spacing between the two first support rings at the front and rear to adapt to aisles of different widths; during the process of the fixing block moving back and forth in the fixing sleeve, the hook head is driven to move back and forth, thereby realizing the adjustment of the spacing between the hook heads located on the front and rear sides of the first support ring. After the fixing block moves, it is fixed by a bolt. Specifically, a threaded hole that is threadedly matched with the bolt can be processed on the fixing sleeve, and the fixing block can be fixed by a bolt. The fixed block independently extends into the fixed sleeve, and after adjusting the position, the fixed block is fixed in the fixed sleeve by bolts; the fixed sleeve moves along the first keel toward the inner and outer sides of the first support ring, thereby driving the hook head to extend out of the first support ring or retract into the inner side of the first support ring; the first film-opening hook and the second film-opening hook of the curved structure increase the spacing between the hook heads installed on the same fixed block, and can quickly break the film from both sides of the cotton seedlings; the first film-opening hook and the second film-opening hook are detachably connected to the hook head, which is convenient for replacing the hook head; the cooperation of the limiting protrusion and the limiting slide groove can prevent the first film-opening mechanism from rotating.

[0010] Furthermore, a groove is provided on the first keel corresponding to the fixing sleeve, and the fixing sleeve can move along the groove toward the inner and outer sides of the first support ring, and a first telescopic assembly driving the fixing sleeve to move along the inner and outer sides of the first support ring is installed in the groove, and the first telescopic assembly includes a movable top block, one end of the top block is connected to the fixing sleeve, and the other end faces the first shaft sleeve and is connected to an air bag, and an air pipe is connected to the air bag, one end of the air pipe is connected to the air bag, and the other end is connected to an air inlet valve and an air discharge valve through an annular air pipe; After the airbag is inflated, the airbag pushes the top block to move toward the outside of the first support ring, thereby pushing the fixing sleeve to move toward the outside of the first support ring, and the hook head extends out of the outside of the first support ring; The first keel is provided with a reset component which drives the fixing sleeve to move toward the inner side of the first supporting ring after the airbag is deflated.

[0011] After the annular air tube is inflated through the air inlet valve and the airbag is inflated through the air tube, the airbag pushes the top block to move toward the outside of the first support ring, and then pushes the fixing sleeve to move toward the outside of the first support ring, and the hook head extends out of the outside of the first support ring; the airbag is deflated through the air release valve, and the reset assembly drives the fixing sleeve to move toward the inside of the first support ring, so as to facilitate the retraction of the hook head to the inside of the first support ring, which not only enables the hook head to extend and retract along the inside and outside of the first support ring, but also when the hook head encounters hard objects during the membrane breaking process, the air release valve can play a role of shock absorption and buffering, thereby reducing the risk of damage to the hook head during the membrane breaking process.

[0013] All the air bags located on the front side of the first keel correspond to one annular air tube, and all the air bags located on the rear side of the first keel correspond to one annular air tube, which facilitates the selection of whether to inflate the air bags on both sides of the front and rear of the first support ring at the same time, thereby adapting to the breaking of the ground film on one side of the aisle when cotton seedlings are planted in a single row or double row.

[0014] Furthermore, the reset assembly includes a tension spring, one end of which is connected to the fixing sleeve, and the other end of which faces the inner side of the first support ring and is connected to a first cover plate covering the first keel; When the tension spring is in a free state, the fixing sleeve moves toward the inner side of the first supporting ring, and the hook head retracts to the inner side of the first supporting ring; When the tension spring is in a stretched state, the fixing sleeve moves toward the outside of the first supporting ring, and the hook head extends out of the outside of the first supporting ring; The outer side of the tension spring is covered with a second protective shell, one end of the second protective shell is fixed to the fixing sleeve and can move with the fixing sleeve.

[0015] After the airbag is deflated, the tension spring can drive the fixed sleeve to move toward the inner side of the first support ring, and the hook head retracts to the inner side of the first support ring for automatic reset, which is very convenient; the first cover plate can protect the internal airbag and trachea, and the second protective shell fixed on the fixed sleeve can always cover the tension spring when the tension spring is in a stretched or free state to play a protective role.

[0016] Furthermore, the film opening wheel is a second film opening mechanism, which includes a second sleeve sleeved on the rotating shaft and having an adjustable position, a second support ring is disposed on the second sleeve, and the second support ring is connected to the second sleeve through a plurality of second keels; A second telescopic assembly for driving the second film opening assembly to move along the inner and outer sides of the second support ring is installed on the second keel, and the second telescopic assembly includes a movable telescopic block, one end of the telescopic block is connected to the second film opening assembly, and the other end faces the inner side of the second support ring and is connected to a driving assembly for driving the telescopic block to move; The driving assembly drives the telescopic block to move toward the outside of the second support ring, and the telescopic block pushes the second film opening assembly to move toward the outside of the second support ring, and the hook head extends out of the outside of the second support ring; The driving assembly drives the telescopic block to move toward the inner side of the second support ring, and the telescopic block pulls the second film opening assembly to move toward the inner side of the second support ring, and the hook head retracts to the inner side of the second support ring.

After the adjusting disk swings to the right, the screw rod of the limiting bolt can extend into one of the limiting holes. After the adjusting disk swings to the left, the screw rod of the limiting bolt can extend into the other limiting hole. A fourth protective shell for protecting the adjusting disk is installed on the second sleeve.

[0019] The telescopic block on the front side of each second keel corresponds to an adjustment block, so that when the adjustment disk swings, all the hooks located on the front side of the adjustment disk are simultaneously driven to extend out of the outside of the second support ring or retract into the inside of the second support ring, so as to realize the rapid adjustment of the extension and retraction of the hooks; all the telescopic blocks located on the rear side of the first keel correspond to an adjustment disk, so that when the adjustment disk swings, all the hooks located on the rear side of the adjustment disk are simultaneously driven to extend out of the outside of the second support ring or retract into the inside of the second support ring, so as to realize the rapid adjustment of the extension and retraction of the hooks; all the telescopic blocks located on one side of the first keel correspond to an adjustment disk, which is convenient for selecting whether the second film opening components on the front and rear sides of the second support ring are extended at the same time, so as to adapt to the film breaking when the ground film on one side of the aisle is planted in a single row or double row of cotton seedlings; a threaded hole threadedly matched with the limit bolt is processed on the third protective shell, and after the adjustment disk swings to the right, the limit bolt can be extended into one of the limit holes, and after the adjustment disk swings to the left, the limit bolt can be extended into another limit hole, which can limit the telescopic block after moving, so as to quickly realize the extension and retraction of the hook head, and the handle is convenient for swinging the adjustment disk.

[0040] The end of the telescopic block 140501 facing the second sleeve 1404 is fixed with a cylindrical adjustment block 140508; Fig. 9 As shown, the second sleeve 1404 is provided with an adjusting disk 140503 of annular structure, and the adjusting disk 140503 is provided with a plurality of adjusting holes 140507 evenly spaced along the circumference, and the adjusting holes 140507 are mounted on corresponding adjusting blocks 140508. The specific number of the adjusting holes 140507 is determined according to the number of the second keels 1406; the adjusting holes 140507 are arc-shaped waist-shaped holes, and the two ends of the adjusting holes 140507 are respectively close to the outer circle and the inner circle of the adjusting disk 140503, and the distance difference between the two ends of the adjusting holes 140507 and the center of the second sleeve 1404 is the distance of the inner and outer adjustment of the second film opening assembly 1403.

[0041] like Figure 8 As shown, two limit holes 140506 are spaced apart on the upper and lower telescopic blocks 140501 in one direction, and the spacing distance is consistent with the distance difference from the two ends of the adjustment hole 140507 to the center of the second shaft sleeve 1404; a third protective shell 140502 of a rectangular plate structure is installed on the outer wall of the telescopic block 140501, and a through hole penetrating the limit hole 140506 is opened on the third protective shell 140502 on one side of the limit hole 140506, and a limit bolt 140505 is installed.

[0042] like Figure 7 and Fig.10 As shown, a handle 1402 is fixed to the side wall of the adjustment plate 140503, located between two second keels 1406, as shown in FIG. Fig. 9 As shown, when the adjustment block 140508 is located at one end of the adjustment hole 140507 close to the inner circle of the adjustment disk 140503, the handle 1402 swings rightward to the right side.

[0043] like Figure 8 and Fig.10As shown, a fourth protective shell 140504 is mounted on the outer side wall of the second keel 1406 to protect the adjustment disk 140503; Fig.10 As shown, a notch is provided on the outer side wall of the fourth protective shell 140504 and one end of the two third protective shells 140502 adjacent to the handle 1402 close to the second shaft sleeve 1404 to avoid interference with the movement of the handle 1402 .

[0044] like Figure 1 and Figure 2 As shown, both front and rear ends of the short rotating shaft 9 are equipped with running wheels 1 , the diameter of the running wheel 1 is larger than the diameter of the first supporting ring 701 , and the sleeve structure of the running wheel 1 is consistent with the structure of the first sleeve 703 .

[0045] like Figure 2 As shown, a fixing assembly 6 is installed at the right end of one of the horizontal pipes of the frame 10; the fixing assembly 6 has a structure as shown in FIG. Fig.11 As shown, it consists of a square block with an upwardly opening "U"-shaped groove, a square cover plate covering the groove is hinged at the top of the "U"-shaped groove, and the cover plate and the square block are connected by T-bolts and butterfly nuts.

[0046] like Figure 2 As shown, a hinge seat 3 is installed at the left end of the crossbar of the frame 10, hinged to two horizontal push rods 5, and a longitudinal push handle 8 is corresponding to the right end of the two push rods 5, which are welded in a two horizontal and one vertical layout. Figure 3 As shown, a notch for installing a traction rod 11 is cut on the right side of the rear half of the push handle 8. The traction rod 11 is a longitudinal cylindrical structure, and a cylindrical sleeve is fixed at the rear end. The sleeve can cooperate with the traction device of other equipment, and the sleeve is a traction sleeve; The front end of the traction rod 11 is hinged at the middle position of the push handle 8 through a pivot, and the rear end can swing left and right; the arc plate produced after the push handle 8 is cut with a notch is fixed to the outer side wall of the traction rod 11, so that when the traction rod 11 and the push handle 8 are both longitudinal, they are in a tongue-and-groove fit, and there will be no notch in the push handle 8; when the traction rod 11 and the push handle 8 are in the same straight line, the traction rod 11 is fixed to the push handle 8 with a metal box buckle.

[0047] like Figure 1 and Figure 2 As shown, a square-structured storage tray 4 is detachably mounted on the left end of the push rod 5 .

[0048] The instructions for using the above technical solution are as follows: The preparation process before use is as follows: According to the layout of the crops, loosen the locking screw that fixes the first shaft sleeve 703, so that the limiting protrusion of the first shaft sleeve 703 moves forward and backward along the limiting slide groove 13, adjust the distance between the first support rings 701 on the front and rear sides, so that the two first support rings 701 are respectively located between the two cotton seedlings on the front and rear sides of the push rod 5, tighten the locking screw that fixes the first shaft sleeve 703, and screw it inward into the limiting slide groove 13 to fix the first shaft sleeve 703 on the rotating shaft 9. The limiting protrusion of the first shaft sleeve 703 cooperates with the limiting slide groove 13 to prevent the first film opening mechanism 7 from rotating.

[0049] Loosen the bolts between the fixed block 70501 and the fixed sleeve 70502, adjust the first film opening hook 70503 and the second film opening hook 70504 to the two sides of the corresponding cotton seedlings, and then fix the fixed block 70501 and the fixed sleeve 70502 with bolts. Specifically, a threaded hole can be processed on the fixed sleeve 70502, and the screw of the bolt is extended into the interior to press against the fixed block 70501 for limiting.

[0050] The principle of using the first film opening mechanism 7 is as follows: When there are cotton seedlings on both the front and rear sides of the two first support rings 701, Figure 5 As shown, an air pump is used to inflate the air inlet valves 70408 on both sides of the first film opening mechanism 7, and the air bag 70404 on the corresponding side is expanded through the transmission of the air pipe 70402. The first film opening component 705 is moved along the groove of the first keel 702 toward the outside of the first support ring 701 through the top block 70405, so that the first film opening hook 70503 and the second film opening hook 70504 extend outward from the outer circle of the first support ring 701.

[0051] When the land area is too small or the planting is in the final stage, the position is limited and only a single row of cotton seedlings can be planted, the first film opening assembly 705 inside the first film opening mechanism 7 can be deflated through the deflation valve 70409 in the first telescopic assembly 704, and retracted to the inner side of the outer circle of the first support ring 701 under the action of the tension spring 70406. When the tension spring 70406 is in a free state, the fixed sleeve 70502 moves toward the inner side of the first support ring 701, and the hook head retracts to the inner side of the first support ring 701; when the tension spring 70406 is in a stretched state, the fixed sleeve 70502 moves toward the outer side of the first support ring 701, and the hook head extends out of the outer side of the first support ring 701; the outer side of the tension spring 70406 is covered with a second protective shell 70407, one end of which is fixed to the fixed sleeve 70502 and can move with the fixed sleeve 70502.

[0052] The principle of using the second film opening mechanism 14 is as follows: When there are two rows of cotton seedlings on the ground film 16 on one side of the passage 15, Figure 8 , Fig. 9 and Fig.10 As shown, first take out the limiting bolt 140505, and rotate the adjusting disk 140503 clockwise through the handles 1402 on both sides of the second film opening mechanism 14, so that the adjusting block 140508 is adjusted from the end close to the inner circle of the adjusting disk 140503 to the end close to the outer circle of the adjusting disk 140503. During the movement, the telescopic block 140501 drives the second film opening component 1403 to move along the sliding groove of the second keel 1406 toward the outer side of the second support ring 1401, so that the mold opening hook of the second film opening component 1403 extends out of the outer circle of the second support ring 1401, and then the limiting bolt 140505 is passed through the through hole and the limiting hole 140506 of the third protective shell 140502 to lock it; the adjustment method of the second film opening component 1403 is consistent with that of the first film opening component 705.

[0053] When the land area is too small or at the final stage of planting, the space is limited and cotton seedlings can only be planted in a single row, the limit bolt 140505 is removed, and the second film opening component 1403 on the inner side of the second film opening mechanism 14 rotates the adjusting disk 140503 counterclockwise through the handle 1402 in the second telescopic component 1405, so that the adjusting block 140508 fixed on the telescopic block 140501 moves to the end of the adjusting hole 140507 close to the inner circle of the adjusting disk 140503, and then the limit bolt 140505 is installed to lock it.

[0054] The working process when using manual pushing is as follows: like Fig.11 and Fig.12 As shown, the storage tray 4 is first removed, and the user stands at the push handle 8, unlocks the fixing assembly 6, and holds the push handle 8 with both hands to adjust it to a suitable height. Fig.12 As shown, the driving wheel 1 travels on the aisle 15 between the two ground films 16, and the first film opening mechanism 7 rotates between the two ground films 16. During the rotation, the first film opening hook 70503 and the second film opening hook 70504 are first inserted into the ground film 16 obliquely and smoothly. As the first film opening mechanism 7 rotates, the first film opening hook 70503 and the second film opening hook 70504 are slowly lifted to break and open the ground film 16.

[0055] During the process of opening the ground film 16, the airbag 70404 can play a certain role in reducing shock when the first film opening component 705 collides with a hard object, thereby increasing the service life of the first film opening hook 70503 and the second film opening hook 70504; After the ends of the first film opening hook 70503 and the second film opening hook 70504 become blunt or damaged after long-term use, only the hook heads can be replaced because the hook heads are threaded, thereby reducing the replacement cost of the first film opening hook 70503 and the second film opening hook 70504; When moving a short distance, the push rod 5 can be fixed to the frame 10 through the fixing assembly 6, so as to lift the first film opening mechanism 7 to move a short distance, such as convenient movement when replacing the aisle 15; When moving over long distances, the air in the airbag 70404 is released through the air release valve 70409, and the first film opening assembly 705 is retracted to the inner side of the first support ring 701 through the tension spring 70406, and the first film opening mechanism 7 is used as a wheel, which increases the flexibility of the equipment.

[0056] When the second film opening mechanism 14 is manually pushed to break the ground film 16, the film breaking process is consistent with the film breaking process of the first film opening mechanism 7, but the application of the adjustment disk 140503 can adjust the second film opening component 1403 more quickly.

[0057] The working process of the traction equipment when used is as follows: like Fig.13 As shown, the first film opening mechanism 7 or the second film opening mechanism 14 is reversed, and the states of the first film opening mechanism 7 and the second film opening mechanism 14 are adjusted as above, the traction rod 11 is unfolded along the pivot and is perpendicular to the push handle 8, the traction rod 11 is connected to the traction device of the traction equipment, the storage tray 4 is installed on the push rod 5, and suitable items are placed in the storage tray 4 for counterweight to improve the stability of the travel. During the travel, the working principle is consistent with that when it is manually pushed.
