Description

Technical Field

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

[0002] Cotton seedling stocking is primarily intended to cultivate strong seedlings and promote early growth and development. It is the first step in cotton seedling management. Timely and scientific stocking promotes strong seedlings and early emergence. The principle of stocking is "stocking green, not yellow," meaning that seedlings are stocked when the cotyledons turn from yellow to green, breaking the membrane and stocking them. This avoids improper stocking caused by stocking too early or too late. Stocking also helps prevent high temperatures from scalding the seedlings and the formation of tall, upright seedlings, which are detrimental to the growth of strong, straight seedlings.

[0003] Currently, cotton seedlings are mostly released manually. Planting should begin when 60%-70% of the seedlings have emerged from the soil, their cotyledons have flattened, and their leaves have turned green. In areas with large-scale cotton cultivation, temporary workers are often hired to manually break the soil and release the seedlings to ensure that the seedlings are not affected. This labor cost places a significant financial strain on growers, as it is time-consuming, labor-intensive, and incurs 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 present 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 machine includes a frame, on which two rotating shafts are rotatably installed and spaced apart from each other and arranged longitudinally. A walking wheel is installed on the rotating shaft on the left, and film-opening wheels are installed at both ends of the rotating shaft on the right. Hooks are provided 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 is power-transmitted with the rotating shaft on the right through a transmission mechanism.

[0007] The walking wheel is located in the aisle between the two rows of ground film. When the walking wheel rotates, it moves along the aisle, and drives 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 film, 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 film with different distances can be broken; the hook head that extends and retracts along the inner and outer sides of the film-opening wheel can be adjusted to extend 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 adjustable in position, a first support ring is provided on the first sleeve, and the first support ring is connected to the first sleeve through a plurality of first keels;

[0009] A limiting protrusion is fixed on the inner side wall of the first shaft sleeve, and a limiting sliding groove is provided on the rotating shaft corresponding to the limiting protrusion and slidingly engaged with the limiting protrusion. A locking threaded hole communicating with the inside and outside is provided on the first shaft sleeve, and a locking screw is installed in the locking threaded hole and threadedly engaged with the locking screw. When the first shaft sleeve moves along the rotating shaft, the first shaft sleeve is fixed to the rotating shaft by the locking screw.

[0010] A first film opening assembly is provided 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 provided 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, 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.

[0011] When the locking screw is actually used, it is screwed inward into the limiting slot 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 slot, thereby driving the first support ring to move back and forth, thereby adjusting the distance between the front and rear two first support rings to adapt to aisles of different widths; during the process of moving the fixing block back and forth in the fixing sleeve, the hook head is driven to move back and forth, thereby adjusting the distance between the hook heads on the front and rear sides of the first support ring. After the fixing block is moved, it is fixed by a bolt. Specifically, a threaded hole that is threadedly matched with the bolt can be processed on the fixing sleeve to fix the fixing block. 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 outward from 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.

[0012] Furthermore, a groove is formed on each of the first keels corresponding to the fixing sleeves, and the fixing sleeve can move along the groove toward the inner and outer sides of the first support ring. A first telescopic assembly is installed in the groove to drive the fixing sleeve to move along the inner and outer sides of the first support ring. 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 airbag. The airbag is connected to an air pipe, one end of the air pipe is connected to the airbag, and the other end is connected to an air inlet valve and an air release valve through an annular air pipe.

[0013] 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;

[0014] The first keel is provided with a reset assembly which drives the fixing sleeve to move toward the inner side of the first support ring after the air bag is deflated.

[0015] 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, which facilitates the retraction of the hook head to the inside of the first support ring, not only realizing the extension and retraction of the hook head 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 plays a role of shock absorption and buffering, thereby reducing the risk of damage to the hook head during the membrane breaking process.

[0016] Furthermore, there are one annular air tube at the front and one at the back. The annular air tube at the front is fixed to the first sleeve at the front of the first keel, and all the air bags at the front of the first keel are connected through the air tube; the annular air tube at the back is fixed to the first sleeve at the back of the first keel, and all the air bags at the back of the first keel are connected through the air tube.

[0017] A first protective shell for protecting the corresponding annular air pipe is fixed on the first shaft sleeve.

[0018] All the air bags located in front of the first keel correspond to one annular air tube, and all the air bags located behind the first keel correspond to one annular air tube, which makes it convenient to choose whether to inflate the air bags on both sides of the first support ring at the same time, so as to adapt to the breaking of the ground film on one side of the aisle when the cotton seedlings are planted in a single row or double row.

[0019] 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;

[0020] 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;

[0021] 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;

[0022] 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.

[0023] 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, thereby playing a protective role.

[0024] Furthermore, the film opening wheel is a second film opening mechanism, which includes a second sleeve sleeved on the rotating shaft and adjustable in position, a second support ring is provided on the second sleeve, and the second support ring is connected to the second sleeve through a plurality of second keels;

[0025] A second telescopic assembly is installed on the second keel to drive the second membrane opening assembly to move along the inner and outer directions of the second support ring. The second telescopic assembly includes a movable telescopic block, one end of the telescopic block is connected to the second membrane 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;

[0026] 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;

[0027] 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.

[0028] The position adjustment method of the second shaft sleeve is the same as the position adjustment method of the first shaft sleeve, and a limit protrusion is fixed on the inner side wall of the second shaft sleeve, and a limit sliding groove is provided on the rotating shaft to slide forward and backward with the limit protrusion, and a locking threaded hole communicating with the inside and outside is provided on the second shaft sleeve, and a locking screw threadedly matched with it is passed through the locking threaded hole. When the second shaft sleeve moves along the rotating shaft, the second shaft sleeve is fixed to the rotating shaft through the locking screw; the structure of the second film opening assembly is the same as that of the first film opening assembly, including a fixing sleeve fixed to the end of the telescopic block, a fixing block that can move back and forth is provided in the fixing sleeve, and two film opening hooks connecting hook heads are fixed on the fixed block; the driving assembly drives the telescopic block to move toward the outer side of the second support ring, the telescopic block pushes the second film opening assembly to move toward the outer side of the second support ring, and the hook head extends out of the outer side of the second support ring; the driving assembly drives the telescopic block to move toward the inner side of the second support ring, 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 into the inner side of the second support ring, and the hook head can be quickly adjusted to extend and retract.

[0029] Furthermore, the driving assembly includes an adjustment disk that is sleeved on the second shaft sleeve and can swing left and right, a handle that is fixed to the adjustment disk for easy swinging, an adjustment hole with an arc-shaped structure is opened on the adjustment disk corresponding to each second keel, and an adjustment block is independently installed in the adjustment hole, and the side of the adjustment block facing the second keel is fixed to the corresponding telescopic block;

[0030] Swing the adjusting plate left and right, the telescopic block moves along the second keel toward the inner and outer sides of the second support ring, driving the second membrane opening assembly to move along the second keel toward the inner and outer sides of the second support ring, and the hook head extends out of the outer side of the second support ring or retracts into the inner side of the second support ring;

[0031] A third protective shell covering the telescopic block is installed on the second keel. The third protective shell is provided with a limit bolt for limiting the movement of the telescopic block. The telescopic block is provided with two limit holes which are connected front to back and through which the screw rods of the limit bolts can pass independently. After the adjusting disk swings to the right, the screw rod of the limit bolt can extend into one of the limit holes. After the adjusting disk swings to the left, the screw rod of the limit bolt can extend into the other limit hole. A fourth protective shell for protecting the adjusting disk is installed on the second shaft sleeve.

[0032] The telescopic block on the front side of each second keel corresponds to an adjustment block, so that when the adjusting disk swings, all the hook heads on the front side of the adjusting 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, thereby realizing rapid adjustment of the extension and retraction of the hook heads; all the telescopic blocks on the rear side of the first keel correspond to an adjustment disk, so that when the adjusting disk swings, all the hook heads on the rear side of the adjusting 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, thereby realizing rapid adjustment of the extension and retraction of the hook heads; all the telescopic blocks on one side of the first keel correspond to an adjustment disk, which is convenient for selecting whether the second film opening assemblies on the front and rear sides of the second support ring are extended at the same time, thereby adapting to the breaking of the ground film on one side of the aisle when the cotton seedlings are planted in a single row or double row; a threaded hole is processed on the third protective shell, which is threadedly matched with the limit bolt. After the adjusting disk swings to the right, the limit bolt can be extended into one of the limit holes, and after the adjusting disk swings to the left, the limit bolt can be extended into the other limit hole, which can limit the movement of the telescopic block, thereby quickly realizing the extension and retraction of the hook heads, and the handle facilitates the swinging of the adjusting disk.

[0033] Furthermore, a horizontal push rod is hinged on the frame through a hinge seat. The left end of the push rod is hinged to the hinge seat, and the right end can swing up and down and is connected to a longitudinal push handle. A fixing component for fixing the push rod after it swings downward is installed on the frame on the right side of the hinge seat.

[0034] The push handle is convenient for pushing and pulling the frame to drive the rotating shaft to rotate, and then drive the traveling wheel and the film-opening wheel to roll; the fixing component is convenient for short-distance movement, and the push rod can be fixed to the frame through the fixing component to lift the film-opening wheel and move a short distance through the traveling wheel to prevent the hook head from contacting the ground and being damaged.

[0035] Furthermore, a transverse traction rod is hinged on the push handle, the left end of the traction rod is hinged to the push handle, and the right end is fixed with a traction cylinder that is connected up and down and can swing backward. After swinging backward, it can be detachably connected to the push handle.

[0036] The traction cylinder at the right end of the traction rod is convenient for connecting with the traction equipment, making work more labor-saving. When the traction equipment is not in use, the right end of the traction rod is swung backward and detachably connected to the push handle and fixed on the push handle, which is convenient for storage without hindering the use of the push handle.

[0037] Furthermore, a bearing seat for mounting a rotating shaft is fixed on the frame, and a storage tray is detachably mounted on the frame.

DETAILED DESCRIPTION

[0055] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0056] Example

[0057] The cotton seedling placing machine described in this embodiment is implemented using the following scheme:

[0058] like Figure 1 and Figure 2 As shown, two longitudinal rotating shafts 9 are made, one long and one short. The rotating shafts 9 are both hollow circular tubes and are arranged at intervals on the left and right. Figure 2 and Figure 5 As shown, a rectangular limiting sliding groove 13 along the front-to-back direction is formed by stamping at both the front and rear ends of the rotating shaft 9 .

[0059] like Figure 1 and Figure 2 As shown, both shafts 9 are driven to rotate by the transmission mechanism 2. Figure 5As shown, the transmission mechanism 2 is a sprocket drive, mainly composed of a sprocket, a chain and a protective shell. The two sprockets of the transmission mechanism 2 are respectively fixed in the middle position of the two rotating shafts 9, and the two sprockets are connected by a chain. The outer sides of the sprockets and the chain are covered with a metal protective shell.

[0060] like Figure 2 As shown, the two rotating shafts 9 are connected by a frame 10. There are two frames 10, each including a horizontal hollow tube, with a sleeve fixed longitudinally at each end. The sleeve is sleeved on the rotating shaft 9, and bearing seats 12 are fixed at the front and rear ends of the sleeve. Specifically, the rotating shaft 9 is installed in the bearing seat 12 and fixed to the bearing in the bearing seat 12. The sleeve is restricted to the rotating shaft 9 between the two bearing seats 12 to prevent the rotating shaft 9 and the frame 10 from displacement. The two frames 10 are respectively located on the front and rear sides of the transmission mechanism 2; during actual installation, the rotating shaft 9 can also be independently installed in the sleeve, and a clamp is fixed on the rotating shaft 9 on the front and rear sides of the sleeve to limit the sleeve, which can prevent the rotating shaft 9 and the sleeve from displacement front and back, and the rotating shaft 9 can also rotate.

[0061] like Figure 2 As shown, the first film opening mechanism 7 or the second film opening mechanism 14 is installed at the front and rear ends of the long rotating shaft 9 on the right side. The first film opening mechanism 7 or the second film opening mechanism 14 can be selected according to different needs.

[0062] like Figure 4 、 Figure 5 and Figure 6 As shown, the first film opening mechanism 7 includes a first support ring 701. The interior of the first support ring 701 is connected to a first shaft sleeve 703 via a plurality of first square keels 702. The first shaft sleeve 703 is located at the center of the first support ring 701. The first support ring 701, the first keel 702 and the first shaft sleeve 703 form a structure similar to a wheel hub.

[0063] like Figure 5 and Figure 6 As shown, a limiting protrusion is fixed on the inner wall of the first sleeve 703, the width of the limiting protrusion is consistent with the width of the limiting groove 13, and the limiting protrusion and the limiting groove 13 are installed in a forward and backward sliding manner; Figure 6 As shown, a platform is machined at each of the front and rear ends of the first sleeve 703, and a threaded hole communicating with the inside and outside is machined inwardly on the platform. The threaded hole is a locking threaded hole, and a locking screw is threadedly installed in the threaded hole;

[0064] The first keel 702 is equipped with a first telescopic assembly 704, which includes an air bag 70404. Figure 5 and Figure 6As shown, a rectangular groove communicating with the first support ring 701 is provided on both the front and rear sides of the first keel 702 facing the outer end of the first support ring 701. An air bag 70404 with a rectangular structure is installed at one end of the rectangular groove facing the inner side of the first support ring 701. A first film opening assembly 705 is installed at the end of the rectangular groove close to the first support ring 701.

[0065] like Figure 6 As shown, the main body of the first film opening component 705 is composed of a fixing sleeve 70502 with a square tube structure and a fixing block 70501 with a rectangular parallelepiped structure. The fixing block 70501 is installed in the fixing sleeve 70502 and fixed by bolts. Specifically, a threaded hole that is threadedly matched with the bolt can be processed on the fixing sleeve 70502, and the fixing block 70501 is independently extended into the fixing sleeve 70502. After adjusting the position, the fixing block 70501 is fixed in the fixing sleeve 70502 by bolts; the first film opening hook 70503 and the second film opening hook 70504 are installed on the fixing block 70501. Figure 11 As shown, the first film-opening hook 70503 and the second film-opening hook 70504 are both formed by bending a small-diameter rod into an arc;

[0066] One end of the first film opening hook 70503 and the second film opening hook 70504 are fixed on both sides of the fixed block 70501 respectively, and the other ends of the first film opening hook 70503 and the second film opening hook 70504 are free ends. The free ends of the first film opening hook 70503 and the second film opening hook 70504 are both processed with threaded holes, and the threaded holes are threadedly connected with the hook head of the conical structure. The distance between the free ends needs to be slightly larger than the size of the cotton seedlings. In actual use, the fixing sleeve 70 502 is processed into a hollow structure, and the fixed block 70501 is located in the fixed sleeve 70502. A sliding hole is opened on the fixed sleeve 70502 to pass through the bolt. After the fixed block 70501 moves back and forth, the screw of the bolt slides back and forth along the sliding hole accordingly and is fixed by a nut, limiting the fixed block in this position. The ends of the first film opening hook 70503 and the second film opening hook 70504 fixed to the fixed block 70501 independently extend into the fixed sleeve 70502 and are fixed to the fixed block 70501;

[0067] A top block 70405 with a rectangular parallelepiped structure is provided between the first film opening assembly 705 and the airbag 70404 , and one end of the top block 70405 facing the outside of the first support ring 701 is fixed to the fixing sleeve 70502 of the first film opening assembly 705 .

[0068] like Figure 5 and Figure 6As shown, a groove with a circular cross-section is provided between the inner end of the first keel 702 facing the first support ring 701 and the airbag 70404 for accommodating the trachea 70402. One end of the trachea 70402 is connected to the airbag 70404. An annular trachea 704010 is respectively mounted on the outer walls of the front and rear sides of the first sleeve 703. The annular trachea 704010 located on the front side communicates with the front trachea 70402, and the annular trachea 704010 located on the rear side communicates with the rear trachea 70402.

[0069] The annular air pipe 704010 is respectively connected to an intake valve 70408 and an exhaust valve 70409; the intake valve 70408 adopts an air nozzle, which is a known technology and mainly consists of a valve core, a valve body and a valve cap.

[0070] A first protective shell 70401 for protecting the annular air pipe 704010 is fixed to the outer periphery of the first shaft sleeve 703 ; through holes for installing the air intake valve 70408 and the air release valve 70409 are opened on the outer wall of the first protective shell 70401 .

[0071] like Figure 5 and Figure 6 As shown, first cover plates 70403 are installed on both the front and rear surfaces of the first keel 702. The first cover plate 70403 is a rectangular plate. The inner end of the first cover plate 70403 facing the first support ring 701 is in contact with the first protective shell 70401, and the other end is provided with a rectangular notch for sliding the first film opening assembly 705. The notch size must ensure that when the first film opening assembly 705 is retracted, the first film opening hook 70503 and the second film opening hook 70504 are located within the circumference of the outer side of the first support ring 701.

[0072] like Figure 6 As shown, the outer end of the first cover plate 70403 facing the first support ring 701 is connected to the fixed block 70501 through a tension spring 70406, and the outer side of the tension spring 70406 is covered with a second protective shell 70407 for protection. The second protective shell 70407 and the fixed sleeve 70502 are fixed together and can move with the fixed sleeve 70502. When the tension spring 70406 is in a stretched state, this end can cover the tension spring 70406.

[0073] like Figure 9 and Figure 10 As shown, the overall structure of the second film opening mechanism 14 is mainly composed of a second support ring 1401, a second sleeve 1404 and a second keel 1406; the composition is consistent with the first support ring 701, the first keel 702 and the first sleeve 703 in the first film opening mechanism 7, the second support ring 1401 has the same structure as the first support ring 701, the second keel 1406 has the same structure as the first keel 702, and the second sleeve 1404 has the same structure as the first sleeve 703.

[0074] like Figure 8 As shown, a sliding groove is provided on the second keel 1406 and extends through the second support ring 1401. The sliding groove extends through the second keel 1406 toward the inner and outer ends of the first support ring 701. A second telescopic component 1405 is provided in the sliding groove. The second telescopic component 1405 includes a telescopic block 140501 that is slidably matched with the sliding groove. The telescopic block 140501 is a long square plate. Figure 8 As shown, the second film opening component 1403 is placed in the slide groove of the second keel 1406 and fixed to one end of the telescopic block 140501 close to the second support ring 1401. The structure of the second film opening component 1403 is consistent with that of the first film opening component 705.

[0075] The end of the telescopic block 140501 facing the second sleeve 1404 is fixed with a cylindrical adjustment block 140508; Figure 9 As shown, a circular adjustment disk 140503 is mounted on the second sleeve 1404. Adjustment disk 140503 is provided with a plurality of adjustment holes 140507 evenly spaced along its circumference. These adjustment holes 140507 are mounted on corresponding adjustment blocks 140508. The specific number of adjustment holes 140507 is determined by the number of second keels 1406. Adjustment holes 140507 are arc-shaped, waist-shaped holes, with their ends respectively proximal to the outer and inner rings of adjustment disk 140503. The difference in distance between the ends of adjustment hole 140507 and the center of second sleeve 1404 corresponds to the inner and outer adjustment distance of second membrane opening assembly 1403.

[0076] like Figure 8 As shown, two limiting 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 between the two ends of the adjustment hole 140507 and 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 limiting hole 140506 is opened on the third protective shell 140502 on one side of the limiting hole 140506, and a limiting bolt 140505 is installed.

[0077] like Figure 7 and Figure 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. Figure 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.

[0078] like Figure 8 and Figure 10As shown, a fourth protective shell 140504 is provided on the outer side wall of the second keel 1406 for protecting the adjustment disk 140503; Figure 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 .

[0079] like Figure 1 and Figure 2 As shown, running wheels 1 are installed at both the front and rear ends of the short rotating shaft 9 . The diameter of the running wheel 1 is larger than the diameter of the first support ring 701 , and the sleeve structure of the running wheel 1 is consistent with that of the first sleeve 703 .

[0080] 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 is structured as shown in FIG. Figure 11 As shown, it consists of a square block with an upward-opening "U"-shaped groove. A square cover plate is hinged on the top of the "U"-shaped groove to cover the groove. The cover plate and the square block are connected by T-bolts and butterfly nuts.

[0081] like Figure 2 As shown, a hinge seat 3 is installed at the left end of the horizontal bar of the frame 10, which is hinged to two horizontal push rods 5. The right ends of the two push rods 5 correspond to a longitudinal push handle 8, which are welded in a two horizontal and one vertical layout. Figure 3 As shown, a notch is cut on the right side of the rear half of the push handle 8 for installing a traction rod 11. The traction rod 11 is a longitudinal cylindrical structure with a cylindrical sleeve fixed at the rear end. The sleeve can cooperate with the traction device of other equipment. The sleeve is a traction cylinder;

[0082] The front end of the traction rod 11 is hinged to the middle position of the push handle 8 through a pivot, and the rear end can swing left and right; the arc-shaped plate produced by cutting the notch in the push handle 8 is fixed to the outer 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.

[0083] 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 .

[0084] The instructions for using the above technical solution are as follows:

[0085] The preparation process before use is as follows:

[0086] 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, and 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, and 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.

[0087] 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 machined 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.

[0088] The principle of using the first film opening mechanism 7 is as follows:

[0089] 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.

[0090] When the land area is too small or the planting is in its final stages, and space is limited, so only single-row planting is possible, 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. Under the action of the tension spring 70406, the first film-opening assembly 705 is retracted to the inside of the outer circle of the first support ring 701. When the tension spring 70406 is in a free state, the fixed sleeve 70502 moves toward the inside of the first support ring 701, and the hook head retracts to the inside of the first support ring 701. When the tension spring 70406 is in a stretched state, the fixed sleeve 70502 moves toward the outside of the first support ring 701, and the hook head extends out of the outside of the first support ring 701. The outside of the tension spring 70406 is covered by a second protective shell 70407, one end of which is fixed to the fixed sleeve 70502 and can move with the fixed sleeve 70502.

[0091] The principle of using the second film opening mechanism 14 is as follows:

[0092] When there are two rows of cotton seedlings on the ground film 16 on one side of the aisle 15, Figure 8 、 Figure 9 and Figure 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 outside 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 the same as that of the first film opening component 705.

[0093] When the land area is too small or the planting is in the final stage and the location is limited, so that 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.

[0094] The working process when using manual pushing is as follows:

[0095] like Figure 11 and Figure 12 As shown, first remove the storage tray 4, the user stands at the push handle 8, unfastens the fixing assembly 6, and holds the push handle 8 with both hands to adjust it to a suitable height. Figure 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 the ground film 16 and open the film.

[0096] 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;

[0097] After the ends of the first and second film-opening hooks 70503 and 70504 become blunt or damaged after long-term use, only the hook heads can be replaced because they are threaded, thereby reducing the replacement cost of the first and second film-opening hooks 70503 and 70504.

[0098] When moving a short distance, the push rod 5 can be fixed to the frame 10 through the fixing assembly 6, thereby lifting the first film opening mechanism 7 to move a short distance, such as convenient movement when replacing the aisle 15;

[0099] 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.

[0100] 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.

[0101] The working process of the traction equipment when used is as follows:

[0102] like Figure 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 movement. During the movement, the working principle is consistent with that when it is manually pushed.
