Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and relates to a pesticide spraying and pipe collecting machine. Background Art

[0002] During agricultural planting, crops are sprayed with pesticides at regular intervals to control pests and diseases and regulate plant growth. Conventional spraying methods typically utilize sprayers, which typically consist of a spray pump, a hose, and a motor to drive the pump. Modern agricultural planting typically occurs on large-scale farms, which occupy large areas. Consequently, the hoses used for spraying are relatively long, making rewinding the hoses after spraying a particular area a challenge.

[0003] In this regard, a Chinese patent application (application number: 201910949256.X) discloses an automatic tube collecting machine for pesticide spraying, which integrates the functions of spraying and automatic tube collecting. The specific structure is: it includes a pair of vertical frames arranged side by side, a winding roller rotatably connected between the vertical frames, a hose wound on the winding roller, a motor, and a plunger pump for conveying pesticides. The motor drives the plunger pump to convey the pesticide to the hose. The motor is connected to a rotating main shaft passing through the plunger pump. The rotating main shaft is provided with a one-way bearing. The one-way bearing is connected to the winding roller by a pulley transmission. A sliding rod, a reciprocating screw and a slide are rotatably connected to the vertical frame. The reciprocating screw and the winding roller are connected by a chain transmission structure. A concave wheel for tensioning the hose is provided under the slide. When spraying, the motor rotates forward, driving the plunger pump to deliver pesticide to the hose. At this point, the one-way bearing slips, and the reel roller is no longer driven by the motor. The user then pulls the hose to rotate the reel roller, which then rotates the reciprocating screw via a chain drive mechanism, allowing the hose to be pulled free from the reel roller. After spraying is complete, the motor flips, stopping the plunger pump from delivering pesticide. The one-way clutch engages, and the motor, driven by the pulley drive mechanism, reverses to rotate. The reel roller, in turn, rotates the reciprocating screw via a chain drive mechanism, causing the slide to slide back and forth along the reciprocating screw, thus automatically retracting the hose.

[0004] In the aforementioned tube rewinding machine, both when winding and unwinding tubes, the rewinding roller must first be driven to rotate. This rewinding roller then drives the reciprocating screw through a chain drive mechanism to rotate, allowing the tubes to be unwound and wound. This multi-stage transmission method consumes a large amount of driving force. When winding tubes, the motor is driven, consuming a large amount of motor power; when unwinding tubes, the motor is manually pulled, requiring a large amount of manpower to pull them out. This results in inconvenience and low work efficiency.

[0005] In order to improve work efficiency, the conventional practices are: 1. Improve the operating accuracy of the equipment and reduce the energy consumption of each intermediate transmission link, which is costly; 2. Add a power assist system to the winding roller and the reciprocating screw to make the rotation easier, but the structure is complex and the overall weight is heavier. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a spraying pipe collecting machine. The technical problem to be solved by the present invention is that the existing spraying pipe collecting machine requires a large driving force when collecting and releasing the pipe, which is inconvenient to use and has low efficiency.

[0007] The objectives of the present invention can be achieved through the following technical solutions: a spray pipe collecting machine, comprising a frame, a motor, a reciprocating screw, a nut slide and a winding roller for winding and rewinding the hose, the winding roller being rotatably connected to the frame, and characterized in that the reciprocating screw is fixed on the frame and arranged parallel to the winding roller, the nut slide can rotate and can move back and forth along the reciprocating screw by rotation, the nut slide has a circular winding groove, the frame is also provided with a guide frame and the hose can extend from the winding roller to insert into the winding groove and pass through the guide frame to achieve reversing, and the guide frame can slide back and forth with the nut slide.

[0008] The hose is then pulled back and forth by the guide frame so that the hose can be straightened and wound around the nut slide, and a large friction force can be generated between the hose and the bottom of the winding groove of the nut slide. The friction force can drive the nut slide to rotate on the reciprocating screw to achieve reciprocating movement, which is equivalent to making the nut slide have the function of a fixed pulley, thereby eliminating the chain transmission mechanism between the winding roller and the reciprocating screw, which is equivalent to eliminating the middle first-level transmission mechanism, thereby avoiding the capacity loss of the intermediate transmission. At the same time, it is more convenient to apply force, and under the same circumstances, the required driving force is also smaller. That is to say, in this application, by cooperating with the guide frame and the winding groove on the nut slide, the nut slide not only plays a conventional role, but also has the role of a fixed pulley, which can achieve self-drive, making the tube winding and releasing more convenient, reducing energy consumption and improving work efficiency.

[0009] In the aforementioned spray tube retractor, the guide frame includes two limit plates, with a first guide wheel and a second guide wheel connected between the two limit plates, both of which are rotatable. The first guide wheel and the second guide wheel are respectively disposed at opposite ends of the limit plates, and a guide channel is formed between the first guide wheel, the second guide wheel, and the two limit plates, through which the hose can pass. The structural design of the guide channel serves to guide and limit the hose, allowing the hose to remain embedded in the rewinding groove at all times and also achieving reversal. Therefore, whether rewinding or unwinding the hose, the hose is wound and tensioned on the nut slide, generating a large friction force between the hose and the bottom of the rewinding groove of the nut slide. This friction force drives the nut slide to rotate on the reciprocating screw to achieve reciprocating movement, which is equivalent to giving the nut slide the function of a fixed pulley, thereby eliminating the chain transmission mechanism between the rewinding roller and the reciprocating screw, and thus eliminating the intermediate first-stage transmission mechanism, thereby avoiding intermediate transmission capacity loss. This also makes it easier to apply force, and under the same conditions, the required driving force is also reduced. The design of the guide wheel one and the guide wheel two that can rotate at the same time can also play the role of a tensioning guide roller, and play a role in assisting the collection and release of the tube, making it more lightweight and smooth.

[0010] In the aforementioned spray tube collecting machine, a connecting rod is fixed to the frame, the connecting rod being arranged parallel to the reciprocating screw. The connecting rod passes through the limit plate and guide wheel 1, and the guide frame is capable of sliding along the connecting rod. By providing the connecting rod parallel to the reciprocating screw, the guide frame is capable of sliding along the connecting rod, thereby enabling the guide frame to achieve synchronous reciprocating movement with the nut slide during the tube collecting and releasing process.

[0011] In the above-mentioned spray tube retractor, the central axis of the reel, the central axis of the nut slide, and the central axis of the connecting rod are arranged in a triangular shape. With this arrangement, the hose extends from the reel and first inserts into the reeling groove of the nut slide, and then passes through the guide frame to achieve reversal. In this way, whether in the process of reeling in or unreeling the hose, the hose is straightened and then wound and tensioned on the nut slide. A large friction force is generated between the hose and the bottom of the reeling groove of the nut slide. This friction force drives the nut slide to rotate on the reciprocating screw to achieve reciprocating movement, which is equivalent to giving the nut slide the function of a fixed pulley, thereby eliminating the chain transmission mechanism between the reel and the reciprocating screw, which is equivalent to eliminating the intermediate first-level transmission mechanism, thereby avoiding the loss of intermediate transmission capacity. This also makes it easier to apply force, and under the same conditions, the required driving force is also smaller.

[0012] In the above-mentioned spray tube collecting machine, the guide frame also includes two arc-shaped pressure plates, each formed by extending outwards from one end of two limiting plates provided with a guide wheel 1. A rotatable pressure wheel 1 and a pressure wheel 2 are connected between the two pressure plates. The pressure wheels 1 and 2 are spaced apart along the arc length of the pressure plates, and the pressure wheels 1 and 2 can be pressed against the opening edge of the rewinding groove. Through the above-mentioned design, the hose can be limited in the rewinding groove, that is, whether in the process of rewinding or releasing the tube, the hose remains embedded in the rewinding groove, thereby driving the nut slide to rotate and achieve reciprocating movement, so that the hose can be evenly wound axially on the rewinding roller or smoothly pulled out on the rewinding roller. At the same time, the pressure wheels 1 and 2 can rotate, which can play a guiding and auxiliary role in the process of releasing and rewinding the tube, making the operation easier and requiring less driving force. In addition, the first and second pressure wheels and the two pressure plates can swing up and down around the connecting rod as a whole, and are pressed on the nut slide by gravity. During the process of collecting and releasing the tube, even if the hose is partially bent or knotted, the overall up and down swing of the guide frame allows the bent or knotted parts of the hose to pass smoothly without getting stuck or stuck, thereby ensuring smooth collection and release of the tube.

[0013] In the aforementioned spray tube retractor, the arc length of the pressure plate is greater than the length of the limit plate, the first pressure wheel is disposed in the middle of the pressure plate, and the second pressure wheel is disposed at the end of the pressure plate away from the limit plate. The arc length of the pressure plate is greater than the arc length of the limit plate, thereby enabling the entire guide frame to form a seesaw-like structure. Under the action of gravity, the first and second pressure wheels can press against the nut slide, allowing the hose to be confined within the reeling groove. That is, whether in the process of reeling in or unreeling the hose, the hose remains embedded in the reeling groove, thereby driving the nut slide to rotate and achieve reciprocating movement, allowing the hose to be evenly axially wound around the reeling roller or smoothly pulled out from the reeling roller. If the hose is partially bent or tangled, the first and second tension wheels are forced to swing upward, allowing the bent or tangled portion of the hose to pass smoothly without getting stuck or stuck, thereby ensuring smooth reeling and unreeling.

[0014] In the aforementioned spray hose retractor, the outer diameter of the second pressure wheel is larger than the outer diameter of the second guide wheel. The second pressure wheel and the second guide wheel are located at opposite ends of the retractor, respectively, away from the hinged connection with the connecting rod. Setting the outer diameter of the second pressure wheel larger than the outer diameter of the second guide wheel makes the second pressure wheel heavier than the second guide wheel. In a natural state, the second pressure wheel can press against the nut slide, thereby confining the hose within the reeling groove. The upward tilt of the second guide wheel can better serve as a tensioning guide, thereby allowing the hose to be evenly wound axially around the reeling roller or smoothly pulled out from the reeling roller.

[0015] In the aforementioned spray hose collecting machine, the limit plate is disposed upwardly and obliquely relative to the pressure plate. This oblique upward arrangement of the limit plate creates a slope between the first and second guide wheels. As a result, during the hose unwinding process, the straightened hose can be better tensioned between the first and second guide wheels. The rolling assistance of the first and second guide wheels allows the hose to be pulled out more easily for unwinding.

[0016] In the aforementioned spray tube retractor, the nut slide includes a disc-shaped wheel portion coaxially arranged with the reciprocating screw, with the retraction groove defined on the outer circumferential wall of the wheel portion. The coaxiality of the wheel portion with the reciprocating screw allows for smoother and more stable rotation on the reciprocating screw, thereby enabling smoother tube retraction and release. Preferably, both sides of the wheel portion have a plurality of radially radiating reinforcing ribs.

[0017] The aforementioned sprayer tube collecting machine further includes a pesticide delivery pump. A motor is connected to the pump and is capable of driving the pump to deliver pesticide to the hose. A pulley is rotatably connected to the pump body or the frame of the pump. The pulley is connected to the take-up roller via a belt drive, and the motor and pulley are connected via a clutch. In this sprayer tube collecting machine, the motor and pulley are connected via a clutch. Therefore, the take-up roller's tube retraction operation and the pump's spraying operation can be driven by the motor rotating in the same direction. For example, both the take-up roller's tube retraction and the pump's spraying operation are driven by the motor's forward rotation. Specifically, the clutch is disengaged, the motor rotates forward, and normal spraying occurs. After spraying is complete, the clutch is engaged to retract the hose. Furthermore, during spraying, the clutch is engaged, allowing spraying and simultaneous tube retraction. This facilitates real-time adjustment of the hose length according to the spraying position, eliminating the need to manually adjust the hose position, making spraying more convenient. At the same time, when releasing the tube before spraying, the clutch can be controlled to engage and the motor can be reversed to achieve automatic tube release, which is more convenient to use.

[0018] Preferably, in the above-mentioned spraying tube collecting machine, the clutch is an electromagnetic clutch. The electromagnetic clutch has a simple structure and can be remotely controlled. Therefore, when using it, only a remote controller is needed to realize remote operation, which is more convenient to use.

[0019] Compared with the existing technology, this spraying pipe collecting machine has the following advantages:

[0020] 1. Through the guide channel of the guide frame and the function of the winding groove on the nut slide, the hose extends from the winding roller and first inserts into the winding groove of the nut slide, and then passes through the guide frame to achieve reversal. In this way, whether in the process of winding or releasing the tube, the hose is straightened and wound and tensioned on the nut slide. Through the action of mutual friction, the nut slide not only plays a conventional role, but also has the function of a fixed pulley, which can achieve self-drive, eliminating the chain transmission mechanism between the winding roller and the reciprocating screw, avoiding the capacity loss of the intermediate transmission, and making it more convenient to apply force. Under the same conditions, the required driving force is also smaller, which reduces energy consumption and improves efficiency.

[0021] 2. The entire guide frame is divided into a clamping part and a guiding part, forming a seesaw-like structure. In its natural state, the clamping part can press against the nut slide, so that the hose can be restrained in the reeling groove, thereby driving the nut slide to rotate and achieve reciprocating movement, so that the hose can be evenly wound axially on the reel or smoothly pulled out from the reel. If the hose is partially bent or tangled, the clamping part is forced to swing upward, allowing the bent or tangled part of the hose to pass smoothly without getting stuck or stuck, ensuring smooth tube collection and release.

[0022] 3. The guide part of the guide frame adopts a rotatable guide wheel 1 and guide wheel 2 structure, and the pressing part adopts a rotatable pressing wheel 1 and pressing wheel 2 structure. Therefore, during the process of collecting and releasing the pipe, the friction rotation can also play a guiding role, making the collection and release of the pipe more labor-saving.

[0023] 4. The clutch between the motor and the reel is used to control the clutch, which can realize the hose retraction while spraying, so that the length of the hose can be adjusted in real time according to the different spraying positions during the spraying process, without the need to pull the hose to adjust the position; at the same time, it can also realize automatic tube release and automatic tube retraction, which is more convenient to use.

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1-3 As shown, the present spray hose collecting machine comprises a frame 1, a motor 2, a drug delivery pump 10, a reciprocating screw 3, a nut slide 4, and a reel 5 for winding and reeling a hose 6. The motor 2 is connected to the drug delivery pump 10 and is capable of driving the drug delivery pump 10 to deliver pesticide to the hose 6. The reel 5 is rotatably connected to the frame 1. A pulley 11 is rotatably connected to the pump body of the drug delivery pump 10 or to the frame 1. The pulley 11 and the reel 5 are connected by a belt 12. The motor 2 and the pulley 11 are connected by a clutch 7. In this embodiment, the drug delivery pump 10 is a plunger pump. The pulley 11 is rotatably connected to the pump housing of the drug delivery pump 10. The reel 5 comprises a cylindrical or columnar reel portion and a disc-shaped runner portion located at each end of the reel portion. A belt 12 groove is circumferentially defined on the outer peripheral wall of one of the runner portions. The belt 12 is embedded in the belt 12 groove. The clutch 7 is an electromagnetic clutch 7. In this sprayer, the reeling roller 5 retracts the tube and the drug delivery pump 10 sprays the medicine through the forward rotation of the motor 2. Specifically, the clutch 7 is controlled to disengage, the motor 2 rotates forward, and the medicine is sprayed normally; after the spraying is completed, the clutch 7 is controlled to engage to retract the tube. Moreover, during the spraying process, by controlling the clutch 7 to engage, the tube can be retracted while spraying, thereby facilitating the real-time adjustment of the length of the hose 6 according to the different spraying positions during the spraying process. There is no need to laboriously pull the hose 6 to adjust the position, making spraying more convenient. At the same time, when releasing the tube before spraying, the clutch 7 can be controlled to engage and the motor 2 can be reversed to achieve automatic release, which is more convenient to use. This sprayer also includes a remote control that can be remotely operated, making it more convenient to use.

[0033] Specifically, if Figure 3 、 5As shown in Figures 6 and 7, the reciprocating screw 3 is fixed to the frame 1 and arranged parallel to the winding roller 5. The nut slide 4 has a disc-shaped wheel portion 4a arranged coaxially with the reciprocating screw 3. The wheel portion 4a is sleeved on the reciprocating screw 3 and can rotate. A cylindrical mounting portion 4b protrudes from one side of the wheel portion 4a. A guide pin 4c is provided in the mounting portion 4b. One end of the guide pin 4c passes through the mounting portion 4b, and the end surface of the protruding end is an arc-shaped surface 4c1 that cooperates with the outer circumference of the reciprocating screw 3. The arc-shaped guide strip 4c2 is provided on the arc-shaped surface 4c1. The guide strip 4c2 is fitted into the spiral tooth groove of the reciprocating screw 3. Under the mutual cooperation of the guide strip 4c2 and the spiral tooth groove, the nut slide 4 can be moved back and forth along the reciprocating screw 3 by rotating the wheel portion 4a. A circular winding groove 4a1 is opened on the outer wall of the wheel part 4a along the circumferential direction. A guide frame 8 is also provided on the frame 1, and the hose 6 can extend from the winding roller 5, insert into the winding groove 4a1 and pass through the guide frame 8 to achieve reversal. The guide frame 8 can slide back and forth with the nut slide 4.

[0034] Further, if Figure 1 、 2 As shown in Figures 4 and 5, a connecting rod 9 is fixed to the frame 1 and arranged parallel to the reciprocating screw. The central axes of the winding roller 5, the nut slide 4, and the connecting rod 9 are arranged in a triangular pattern. The guide frame 8 includes two limit plates 8a, with a rotatable guide wheel 1 8b and a rotatable guide wheel 2 8c connected between the limit plates 8a. The guide wheels 1 8b and 2 8c are respectively arranged at opposite ends of the limit plates 8a. The connecting rod 9 passes through the limit plates 8a and the guide wheels 1 8b. A guide channel 8d is formed between the guide wheels 1 8b, the guide wheels 2 8c, and the two limit plates 8a, through which the hose 6 can pass. The guide channel 8d guides and limits the hose 6, ensuring that the hose 6 remains embedded in the reeling groove 4a1 and also achieves reversal. Therefore, whether in the process of reeling in or unreeling, the hose 6 is wound and tensioned on the nut slide 4. A large friction force is generated between the hose 6 and the bottom of the reeling groove 4a1 of the nut slide 4. This friction force drives the nut slide 4 to rotate on the reciprocating screw 3 and achieve reciprocating movement. This is equivalent to giving the nut slide 4 the function of a fixed pulley, thereby eliminating the chain transmission mechanism between the reeling roller 5 and the reciprocating screw 3, and thus eliminating the intermediate first-stage transmission mechanism, thereby avoiding the loss of intermediate transmission capacity. This also makes it easier to apply force, requiring less driving force under the same conditions. The design of the rotatable guide wheel 1 8b and guide wheel 2 8c also acts as a tensioning guide roller, assisting in the reeling and unreeling of the hose, making it easier and smoother.

[0035] Furthermore, the guide frame 8 further includes two arc-shaped pressure plates 8e, each formed by extending outward from one end of the two limiting plates 8a provided with the guide wheel 1 8b. Connected between the two pressure plates 8e are a rotatable pressure wheel 1 8f and a pressure wheel 2 8g. The pressure wheels 1 8f and 2 8g are spaced apart along the arc length of the pressure plates 8e and are capable of pressing against the opening edge of the reeling groove 4a1. This allows the hose 6 to be retained within the reeling groove 4a1. That is, whether the hose is being reeled in or unreeled, the hose 6 remains embedded within the reeling groove 4a1, thereby driving the nut slide 4 to rotate and reciprocate, allowing the hose 6 to be evenly wound axially around the reeling roller 5 or smoothly pulled out of the reeling roller 5. At the same time, the first and second pinch rollers 8f and 8g can rotate, providing guidance and assistance during the tube placement and collection process, making operation easier and requiring less driving force. Furthermore, the first and second pinch rollers 8f and 8g, along with the two pressure plates 8e, can swing up and down around the connecting rod 9, and through gravity, they press against the nut slide 4. During the tube placement and collection process, even if the hose 6 is partially bent or tangled, the overall upward and downward swinging of the guide frame 8 allows the bent or tangled portion of the hose 6 to pass smoothly without getting stuck or stuck, ensuring smooth tube placement and collection.

[0036] The arc length of the pressure plate 8e is greater than the length of the limiting plate 8a. The first pressure wheel 8f is located in the middle of the pressure plate 8e, and the second pressure wheel 8g is located at the end of the pressure plate 8e away from the limiting plate 8a, thereby forming a seesaw-like structure for the entire guide frame 8. The outer diameter of the second pressure wheel 8g is greater than the outer diameter of the second guide wheel 8c. The second pressure wheel 8g is heavier than the second guide wheel 8c. In a natural state, the end of the second pressure wheel 8g can be pressed against the nut slide 4 under the action of gravity, so that the hose 6 can be limited in the winding groove 4a1. The end of the second guide wheel 8c is tilted upward, which can better serve as a tension guide, so that the hose 6 can be evenly wound axially around the winding roller 5 or smoothly pulled out from the winding roller 5.

[0037] In addition, the limit plate 8a is arranged to be inclined upward relative to the pressure plate 8e, so that there is also a slope between the guide wheel 1 8b and the guide wheel 2 8c. Therefore, during the pipe releasing process, the hose 6 can be better tensioned between the guide wheel 1 8b and the guide wheel 2 8c after being straightened. Through the rolling assistance of the guide wheel 1 8b and the guide wheel 2 8c, the hose 6 can be pulled out more easily to achieve pipe releasing.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
