Detailed Description

In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

In the description of the present invention, unless otherwise specified and limited, it is to be noted that the term "connected" is to be interpreted broadly, and may be, for example, a mechanical connection or an electrical connection, or a communication between two elements, or may be a direct connection or an indirect connection through an intermediate medium, and a specific meaning of the term may be understood by those skilled in the art according to specific situations.

The weed rake usually has at least two rake handles, when the two rake handles are entangled by the weed, the cleaner needs to exert a great force to pull out the weed rake from the weed pile, in order to pull out the weed rake from the weed pile more easily, the weed wound between the two rake handles can be cut, so that the weed wound on the rake handles can completely fall off from the two rake handles, or the weed can be wound on a single rake handle. After the aquatic weeds between the rake handles are cut, the cleaner can try to continue to transfer the aquatic weeds, and if the water weed rake can be moved without taking much labor, the aquatic weeds are shown to fall off from the rake handles, and the cleaner can continue to transfer the aquatic weeds without pulling out the water weed rake; if the weed removal harrow can not be moved by force, the reason is that although the weeds between the harrow handles are removed, the weeds are still wound on the single harrow handles, and at the moment, a cleaner needs to pull out the single harrow handles in sequence to remove the weeds on the single harrow handles, and then the weed removal harrow is continuously used for transferring the weeds. Compared with the situation that two harrow handles are pulled out simultaneously, the force required for pulling out a single harrow handle one by one is obviously smaller, and especially the cleaner with smaller force is more urgent, so that the aquatic weeds wound between the two harrow handles can be cut, the labor is saved, and the force requirement on the cleaner is reduced. In order to cut the aquatic weeds wound between the rabble arms, the applicant proposed to provide a cutting mechanism between the rabble arms. When the cutting mechanism is used for cutting the aquatic weeds wound between the harrow handles, the applicant designs a control mechanism for cutting.

Referring to fig. 1, a flow chart of an embodiment of the cutting mechanism for cutting the waterweeds wound between the two rake handles according to the method for controlling the rake for removing waterweeds of the present invention is shown. The control method is applied to a dewatering grass rake, the dewatering grass rake comprises a controller, two rake handles and a cutting mechanism located between the rake handles, the two rake handles are respectively connected with the front side of a supporting plate, the cutting mechanism is connected with the front side of the supporting plate through a first electric telescopic rod, the rear side of the supporting plate is connected with a holding rod, the front end of each rake handle is provided with a hook-shaped structure, and the controller controls the dewatering grass rake according to the following method:

step S107, judging whether the output power of the cutting mechanism is no-load power, if so, executing step S108, otherwise, continuing to execute step S107; in step S107, if the output power of the cutting mechanism is determined to be the idle power, the controller first sends a first prompt signal to the prompt device to prompt the prompt device that the waterweeds wound between the rake handles are cut, and then executes step S108.

In this embodiment, when the water grass is collected to the cleanup crew utilizing the water grass rake, if can't remove the water grass rake, it has been entangled by the water grass to show the water grass rake, the corresponding button on the water grass rake can be pressed to the cleanup crew this moment, the first cutting signal is received to the controller on the water grass rake, controller control cutting mechanism begins working this moment, the water grass of winding between two rake handles is cut, when the output power of cutting mechanism here is no-load power, it has been cut completely to show the water grass of winding between two rake handles here, the extension of first electric telescopic handle of controller control thereafter, thereby drive cutting mechanism and move forward, the water grass of winding in different district section between two rake handles is cut one by one. When the first electric telescopic rod extends to a preset first distance, the cutting mechanism is continuously controlled to cut until the output power of the first electric telescopic rod is no-load power, and the aquatic weeds wound in each section between the two harrow handles are cut. After the aquatic weeds in each section between the two harrow handles are cut, the controller sends a first prompt signal to the prompt device, so that the prompt device prompts the cleaner to the result that all the aquatic weeds between the two harrow handles are cut.

It can be seen from the above embodiments that the control flow of the weeding harrow for cutting the aquatic weeds wound between the two harrow arms is designed, so that all the aquatic weeds wound between the two harrow arms can be cut, the cutting effect is ensured, and the cutting reset can be stopped after all the aquatic weeds wound between the two harrow arms are cut, so that the cutting efficiency can be improved, and the cutting energy consumption can be reduced. In addition, after all the aquatic weeds wound between the two rake handles are cut, the cutting result is informed to cleaning personnel through the prompting device, a good man-machine interaction interface is provided, and the user experience is improved.

Obviously, through above-mentioned design, the pasture and water harrow can only cut the pasture and water of winding between two rabble arms, after cutting the pasture and water between two rabble arms, still probably twine pasture and water on the single rabble arm, cleaner still need extract the pasture and water harrow from the pasture and water heap this moment, still have great strength requirement to cleaner at the in-process of extracting to cleaner can only continue to carry out the pasture and water collection work after extracting the pasture and water, has reduced pasture and water collection efficiency like this. Therefore, the invention also designs a control flow of the cutting mechanism for cutting the aquatic weeds wound on the single harrow handle, so that the aquatic weed rake also comprises an angle sensor. In step S107, if the output power of the cutting mechanism is determined to be idle power, before step S108, the controller further performs the following steps, as shown in fig. 2:

In this embodiment, the rake further includes a prompting device, in step S205, if the output power of the cutting mechanism is determined to be the idle power, the controller first sends a second prompting signal to the prompting device, so that the prompting device prompts that the waterweeds wound at the corresponding position on the single rake handle has been cut, and then step S202 is executed. According to the invention, the cutting condition of the aquatic weeds wound at the corresponding positions on the single rake handle is prompted, so that a good man-machine interaction interface can be provided, and the good experience of a user is improved.

After the cleaner knows that all the float grass wound between the two rake handles is cut off through the prompting device, the cleaner can continuously move the float grass rake to try to further collect the moving float grass. If the dewatering grass rake can be moved, the dewatering grass rake is not entangled by the waterweeds, and the cleaner can continue to collect the moving waterweeds without pulling out the dewatering grass rake. If the weed removal rake cannot be moved, the fact that although the weeds between the two rake handles are cut, the weeds still entangle with the single rake handle is shown, and at the moment, a cleaner can press the corresponding key so that the controller receives a second cutting signal.

The controller is after receiving the second cutting signal, and the cleanup crew can make except that the rake slope, and along with the slope gradually of removing the rake, the angle that angle sensor detected also will crescent gradually, when the current angle that angle sensor regularly detected was greater than the angle that detects before, the extension of first electric telescopic handle of controller control utilizes cutting mechanism to cut the pasture and water of winding on single rake handle. Although the rake handle and the cutting mechanism are parallel and both can incline along with the inclination of the rake for removing the aquatic weeds, the relative position relation between the aquatic weeds wound on the single rake handle and the rake handle can also change, so that the cutting mechanism can cut the aquatic weeds wound on the single rake handle after the cutting mechanism extends along with the first electric telescopic rod until the two rake handles are out of the two rake handles. In the process of cutting the aquatic weeds wound on the single rake handle by using the cutting mechanism, the cleaning personnel can repeatedly move the holding rod of the aquatic weed rake along the direction close to and away from the cleaning personnel so as to cut the aquatic weeds wound on the single rake handle in multiple directions, and when the output power of the cutting mechanism is no-load power at the inclination, the aquatic weeds wound on the corresponding rake handle at the inclination are cut.

After that, the prompting device prompts the condition that the aquatic weeds at the corresponding positions of the single rake handles are cut, after receiving the prompt, a cleaner can try to pull out the corresponding rake handles of the aquatic weed rake, if the corresponding rake handles cannot be pulled out, the cleaner continues to incline the corresponding rake handles, and as the current angle periodically detected by the angle sensor is larger than the angle detected before, the first electric telescopic rod further extends, so that the aquatic weeds wound on the corresponding rake handles are further cut by the cutting mechanism; if the corresponding rake handle can be pulled out, the cleaning personnel restore the water removal rake to a vertical state, the current angle detected by the angle sensor is smaller than the angle detected before, and the controller controls the first electric telescopic rod to retract to a first distance. The first electric telescopic rod is contracted to the first distance, so that the cleaner can conveniently determine whether the other harrow handle is wound with the aquatic weeds or not, and further cut when the other harrow handle is determined to be wound with the aquatic weeds. When the cleaner determines that aquatic plants are not wound on the other rake handle, the corresponding button cannot be pressed, the controller cannot receive the second cutting signal, and the cutting mechanism and the first electric telescopic rod are controlled to reset at the moment.

It can be seen from the above embodiments that, in the present invention, the current angle periodically detected by the angle sensor is compared with the angle detected before, the extended length of the first electric telescopic rod is controlled according to the comparison result, as the detected angle becomes larger, the extended length of the first electric telescopic rod is gradually increased, and the cutting force of the waterweeds wound on a single rake handle is gradually increased, so that the cutting effect of the waterweeds on the single rake handle can be realized with lower energy consumption, and in the cutting process of the waterweeds on the single rake handle, a cleaner only needs to perform the operations of pressing a key, inclining the waterweed rake and trying to pull out the waterweed rake, which is labor-saving and simple in operation.

The applicant researches and discovers that in order to completely cut the waterweeds wound on the two rabble arms, the blades in the cutting mechanism need to be arranged outside the space area between the two rabble arms in a protruding mode, but the blades in the cutting mechanism are firstly contacted with the waterweeds, namely, the waterweeds contacted with the waterweed rake are greatly cut, and therefore the collection of the waterweeds is not facilitated. If the aquatic weeds are to be collected, the aquatic weeds must be harrowed in the aquatic weeds collecting process, two harrow handle heads contact with the aquatic weeds firstly, and a blade in a cutting mechanism is positioned in a space area between the two harrow handle heads. However, when the blade of the cutting mechanism is located in the space between the rabble arms, the blade of the cutting mechanism cannot perform its cutting function. Therefore, the invention also designs the water removal grass rake.

Referring to fig. 3 to 4, the rake for removing water grass may include two rake handles 1 and a cutting mechanism 2 located between the two rake handles 1, wherein the two rake handles 1 are respectively connected to the front side of a supporting plate 3, the cutting mechanism 2 is connected to the front side of the supporting plate 3 through a first electric telescopic rod 30, the rear side of the supporting plate 3 is connected to a holding rod 4, a hook structure 11 is disposed at the front end of each rake handle 1, the cutting mechanism 2 is accommodated in a space region between the two rake handles 1 under a non-cutting condition, and a part of a cutting part in the cutting mechanism 2 is protruded out of the space region between the two rake handles 1 under a cutting condition. According to the invention, the cutting mechanism is arranged between the two rake handles of the weed removing rake, so that the aquatic weeds wound between the two rake handles can be cut, the operation of a cleaner is more labor-saving, the time spent by the cleaner for removing the aquatic weeds when the rake handles are wound by the aquatic weeds is reduced, and the weed removing efficiency is improved; according to the invention, the cutting mechanism is accommodated in the space region between the two rake handles of the weed rake under the non-cutting working condition, and part of the cutting part is arranged outside the space region between the two rake handles in a protruding manner under the cutting working condition, so that the cutting mechanism is not directly contacted with aquatic weeds under the non-cutting working condition, and the cutting mechanism can be ensured to fully exert the cutting function under the cutting working condition.

In order to realize that the cutting mechanism is accommodated in the space region between the two harrow arms under the non-cutting working condition, and part of the cutting mechanism is arranged outside the space region between the two harrow arms in a protruding way under the non-cutting working condition, the applicant designs the cutting mechanism arranged between the two harrow arms of the water removal grass harrow. Referring to fig. 3 and 5 to 7, the rake for removing water weed of the present invention may include a guiding metal frame 10, a chain for conveying an electric saw 20, a second electric telescopic rod 40 and a rotating motor 50, wherein the guiding metal frame 10 includes an arc-shaped metal rod 11 and a first metal rod 12 and a second metal rod 13 correspondingly connected to upper and lower ends of the arc-shaped metal rod 11, the arc-shaped metal rod 11 is integrally formed with the first metal rod 12 and the second metal rod 13 and is located at front ends of the first metal rod 12 and the second metal rod 13, the first metal rod 12 and the second metal rod 13 are parallel to each other, rear ends of the first metal rod 12 and the second metal rod 13 are respectively hinged with a guide rod 60, both guide rods 60 are fixedly connected to one surface of a fixing plate 70, the other opposite surface of the fixing plate 70 is fixedly connected to the first electric telescopic rod 30, the fixing plate 70 is pushed and pulled by the first electric telescopic rod 30 to move back and forth, thereby driving the two guide rods 60 to rotate around the first metal rod 12 and the second metal rod 13 correspondingly, and the first metal rod 12 and the second metal rod 13 incline upwards and downwards correspondingly under the action of the two guide rods 60; the electric saw conveying chain 20 is wound around the guide metal frame 10 and the rotating motor 50, and is conveyed around the guide metal frame 10 under the action of the rotating motor 50; the rotating motor 50 is fixedly connected with the second electric telescopic rod 40, and moves back and forth under the action of the second electric telescopic rod 40, the second electric telescopic rod 40 is fixedly connected with the first electric telescopic rod 30, and moves back and forth under the action of the first electric telescopic rod 30, and under the matching action of the first electric telescopic rod and the second electric telescopic rod, the state switching of the cutting mechanism under the cutting working condition and the non-cutting working condition is realized.

In this embodiment, under the non-cutting operating mode, its electric saw conveying chain 20 of cutting mechanism is located the space region between two harrow handles of water removal grass harrow, after getting into the cutting operating mode, at first control first electric telescopic handle 30 extension to correspond and predetermine the distance, then control first electric telescopic handle 30 and the extension of second electric telescopic handle 40 simultaneously to guarantee that first metal pole 12 and second metal pole 13 correspond the in-process electric saw conveying chain 20 that inclines to downside and be in the state of tightening all the time, can not take place to drop. Wherein, the first electric telescopic rod 30 extends to push the fixing plate 70 to move forward, and because the front ends of the two guide rods 60 are correspondingly hinged to the first metal rod 12 and the second metal rod 13, and the rear ends are fixedly connected to the fixing plate 70, in the process of moving forward of the fixing plate 70, the guide rod 60 on the upper side rotates clockwise around the first metal rod 12, and the guide rod 60 on the lower side rotates counterclockwise around the second metal rod 13. When the upper guide bar 60 rotates clockwise, an upward force is provided to the first metal bar 12, the rear end of the first metal bar 12 tilts upward, and the first metal bar 12 inclines upward; when the lower guide bar 60 is rotated counterclockwise, a downward force is applied to the second metal bar 13, the rear end of the second metal bar 13 is tilted downward, and the second metal bar 13 is tilted downward. When the first electric telescopic rod 30 and the second electric telescopic rod 40 extend for a corresponding preset distance and the second electric telescopic rod 40 stops extending, at least a part of the electric saw transmission chain 20 in the cutting mechanism is arranged outside the space area between the two harrow arms in a protruding mode.

After the second electric telescopic rod 40 stops extending and part of the electric saw transmission chain 20 in the cutting mechanism is arranged outside the space area between the two harrow handles in a protruding mode, the rotating motor 50 is controlled to rotate so as to drive the electric saw transmission chain 20 to be transmitted around the guide metal frame 10, and the cutting mechanism starts to cut aquatic weeds. When the electric saw transmission chain 20 cuts the aquatic weeds, the power consumed by the corresponding rotating motor 50 to drive the electric saw transmission chain 20 to transmit is the load power, and when the electric saw transmission chain 20 does not cut the aquatic weeds, the power consumed by the corresponding rotating motor 50 to drive the electric saw transmission chain 20 to transmit is the no-load power, obviously, the load power is greater than the no-load power, so whether the aquatic weeds at the corresponding positions are completely cut can be judged according to the output power of the rotating motor 50. Therefore, when the cutting mechanism starts to cut the aquatic weeds, firstly, whether the output power of the rotating motor 50 is the no-load power is judged, if the output power of the rotating motor 50 is the no-load power, the first electric telescopic rod 30 is controlled to extend continuously for a preset distance, then, whether the rear ends of the first metal rod 12 and the second metal rod 13 in the electric saw conveying chain 20 extend out of two rake handles is judged, if yes, the first electric telescopic rod 30 and the second electric telescopic rod 40 are controlled to reset, and if not, the first electric telescopic rod 30 is controlled to extend continuously for the preset distance; if the output power of the rotating electrical machine 50 is not the no-load power, it is continuously determined whether the output power of the rotating electrical machine 50 is the no-load power until the output power of the rotating electrical machine 50 is the no-load power.

In addition, in order to ensure that the upper guide rod 60 rotates clockwise around the first metal rod 12 and the lower guide rod 60 rotates counterclockwise around the second metal rod 14 in the process of moving the fixing plate 70 forward, a first baffle plate 14 inclined to the left is fixedly arranged at the rear end of the first metal rod 12, a horizontal second baffle plate 15 is fixedly arranged at one side of the first baffle plate 14 facing the rotating motor 50, and the upper guide rod 60 is arranged at the lower side of the second baffle plate 15 and hinged with the first baffle plate 14; a third flap 16 inclined to the right is fixedly provided at the rear end of the second metal rod 13, a horizontal fourth flap 17 is fixedly provided at a side of the third flap 16 facing the rotating electric machine 50, and a lower guide rod 60 is provided at an upper side of the fourth flap 17 and is hinged to the third flap 16. In order to ensure the switching stability, the second baffle is shorter than the first metal rod, and the fourth baffle is higher than the second metal rod. Referring to fig. 1, the fixing plate 70 is disposed in the electric saw transmission chain 20, and the portion of the fixing plate extending out of the electric saw transmission chain 20 is connected to the inner rod of the first electric telescopic rod 30, the first electric telescopic rod 30 and the second electric telescopic rod 40 are respectively located at two sides of the electric saw transmission chain 20, the outer rod of the second electric telescopic rod 40 is connected to the inner rod of the first electric telescopic rod 30 through the first connecting rod 41, and the inner rod is connected to the rotating motor 50 through the second connecting rod 42.

It can be seen from the above embodiments that, by designing the cutting mechanism, the state switching of the cutting mechanism under the cutting working condition and the non-cutting working condition can be realized, so that the cutting mechanism is folded in the space region between the rake handles under the non-cutting working condition, the electric saw transmission chain is arranged outside the space region between the rake handles in a protruding manner under the cutting working condition, and the electric saw transmission chain is used for enabling the part of the electric saw transmission chain which is arranged outside the space region of the rake handles to be the inverted V-shaped blade under the cutting working condition, both sides of the inverted V-shaped blade can cut aquatic weeds, the aquatic weeds can be cut by the electric saw transmission chain in more ranges, and correspondingly, the number of times that the first electric telescopic rod needs to be stretched is reduced, so that the cutting efficiency can be improved. In addition, the electric saw transmission chain mainly utilizes the rotation of the rotating motor to drive the electric saw transmission chain to rub with the aquatic weeds to cut the aquatic weeds, and compared with a sharp blade, the sharpness of the electric saw transmission chain can be lower, so that the smooth collection of the aquatic weeds can be further ensured.
