Description

Technical Field

[0001] This utility model relates to the field of spraying and fertilizing robot technology, and in particular to a spraying and fertilizing robot for greenhouses. Background Technology

[0002] Greenhouse cultivation is a widely used planting technique in modern agriculture. It improves crop yield and quality by artificially controlling environmental conditions. Specifically, it refers to planting crops in closed or semi-closed environments such as greenhouses or plastic tunnels, and providing the most suitable growing conditions for crops by adjusting environmental factors such as temperature, humidity, and light.

[0003] When growing crops in greenhouses, fertilization and pesticide application are the main measures for applying soluble fertilizers and controlling various diseases during greenhouse production, which can ensure the smooth and robust growth of crops. However, the current fertilization and pesticide application are all done manually by staff, which results in low efficiency and makes it difficult to ensure good uniformity of fertilization and pesticide application.

[0004] Chinese utility model patent with publication number CN201920908005.2 discloses a robot for watering, fertilizing, and spraying pesticides on greenhouse plants. Through the setting of spray pipes and nozzles, it can select different height spray pipes to fertilize and spray pesticides on crops according to the height of the crops to be fertilized and sprayed. At the same time, through the walking mechanism, it can automatically walk in the greenhouse and complete the fertilization and pesticide spraying, effectively improving the efficiency of fertilization and pesticide spraying.

[0005] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the nozzle can only be positioned above the crops to spray fertilizer or pesticides. For some crops with dense stems and leaves, it is difficult to spray fertilizer or pesticides evenly on the surface of the crops, thus reducing the effectiveness of fertilization and pesticide application. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a greenhouse spraying and fertilizing robot.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a greenhouse spraying and fertilizing robot, comprising an outer shell, rollers installed at the bottom of the outer shell, two pairs of electric telescopic rods symmetrically fixedly connected to the top of the outer shell, a fixed plate fixedly connected between the output ends of the two pairs of electric telescopic rods, a liquid storage tank fixedly connected to the top of the fixed plate, a liquid pump fixedly connected to the top of the liquid storage tank, an inlet pipe connected to the input end of the liquid pump, the bottom end of the inlet pipe penetrating the top wall of the liquid storage tank and extending to a position close to the inner side wall of the liquid storage tank, a vertical pipe connected to the output end of the liquid pump, a horizontal pipe connected to the top end of the vertical pipe, two vertically distributed outlet pipes symmetrically connected to the bottom of the horizontal pipe, two sets of nozzles symmetrically connected to the outer circumferential surface of the outlet pipe, and a left and right adjustment component provided on the horizontal pipe;

[0008] The left and right adjustment component is used to move the two liquid outlet pipes left and right.

[0009] By adopting the above technical solution, the pesticide or fertilizer solution can be evenly sprayed from top to bottom onto the stems and leaves of crops through two vertical liquid outlet pipes and nozzles connected to them. This ensures that the pesticide or fertilizer solution is more evenly distributed on the stems and leaves of crops, thereby enabling crops to absorb the nutrients in the fertilizer solution more quickly and fully, or enabling the pesticide solution to kill pests and diseases more effectively, thus improving the practicality and reliability of the spraying and fertilizing robot.

[0010] Furthermore, the left-right adjustment assembly includes two flexible tubes symmetrically connected to the bottom of the horizontal tube. The bottom ends of the two flexible tubes are respectively connected to the top ends of the two liquid outlet tubes. The left-right adjustment assembly also includes two first clamping blocks and two second clamping blocks that are movably sleeved on the outer circumference of the horizontal tube through semi-circular grooves. The top ends of the two first clamping blocks and the bottom ends of the two second clamping blocks are connected together by a fastening mechanism. Two through grooves and two rectangular grooves are symmetrically opened on the opposite sides of the two first clamping blocks. The bottom ends of the two through grooves are respectively connected to the top ends of the two rectangular grooves. The bottom ends of the two flexible tubes pass through the two through grooves and the two rectangular grooves and extend to the lower side of the first clamping blocks. The outer sidewalls of the two flexible tubes are respectively attached to the inner sidewalls of the two rectangular grooves and the inner bottom wall of the two through grooves.

[0011] By adopting the above technical solution, by moving the first clamping block left and right along the horizontal tube, the liquid outlet pipe can be moved up and down through the flexible hose under the limitation of the inner side wall of the rectangular groove and the bottom wall of the through groove. This allows adjustment of the left and right positions of the liquid outlet pipe and the nozzle, thereby adjusting the position of the nozzle according to the spacing of the crops and the outer diameter of the stems and leaves. This ensures that the nozzle will not collide with the crop stems and leaves or be too far away from them, ensuring that the pesticide or fertilizer solution sprayed from the nozzle can be fully and smoothly sprayed onto the crop stems and leaves, reducing the waste of pesticide or fertilizer solution and improving the reliability of the spraying and fertilizing robot.

[0012] Furthermore, the fastening mechanism includes two pairs of accommodating cavities symmetrically opened at the bottom of the second clamping block. Two pairs of crossbars are symmetrically and interactively inserted on the left and right sides of the second clamping block. Two first pull plates are symmetrically and fixedly connected between the ends of the two pairs of crossbars that are far apart. Two pairs of first elastic elements are symmetrically and fixedly connected between the sides of the two first pull plates that are close together and the left and right sides of the second clamping block. The ends of the two pairs of crossbars that are close together pass through the left and right side walls of the second clamping block and extend into the two pairs of accommodating cavities. Two pairs of first locking plates are symmetrically and fixedly connected to the ends of the two pairs of crossbars that are close together. The fastening mechanism also includes two pairs of connecting rods symmetrically and fixedly connected to the top of the first clamping block. Two pairs of second locking plates are symmetrically and fixedly connected to the top of the two pairs of connecting rods. The two pairs of second locking plates can be inserted into the two pairs of accommodating cavities and their bottoms are respectively pressed against the top of the two pairs of first locking plates. The corners where the first locking plates and the second locking plates are close together are inclined surfaces with the same inclination. When the second locking plate is locked by the first locking plate, the top surface of the second locking plate abuts against the inner top wall of the accommodating cavity.

[0013] By adopting the above technical solution, it is possible to simply pull the two first pull plates in opposite directions until the two first clamping plates are located on the left and right sides of the two second clamping plates respectively. At this time, the second clamping plates can be detached from the receiving cavity, so that the first clamping block and the second clamping block can be separated quickly and conveniently. Conversely, since the corners where the first clamping plates and the second clamping plates are close together are inclined planes with the same inclination, the operator only needs to insert the two pairs of first clamping plates upward into the receiving cavity. Under the action of the inclined plane, the second clamping plates can push open the first clamping plates and move to the upper side of the first clamping plates. In this way, the first clamping plates can fasten the second clamping plates in the receiving cavity, making the connection operation of the first clamping blocks and the second clamping blocks simple and convenient, and improving the convenience and practicality of the robot.

[0014] Furthermore, the fastening mechanism also includes two pairs of vertical rods symmetrically and movably inserted into the top of the second clamping block. Two second pull plates are symmetrically and fixedly connected between the top ends of the two pairs of vertical rods. Two pairs of second elastic elements are symmetrically and fixedly connected between the bottom of the two second pull plates and the top of the second clamping block. The bottom ends of the two pairs of vertical rods penetrate the top wall of the second clamping block and extend into the two pairs of receiving cavities respectively, and are fixedly connected to the top of the two pairs of second clamping plates.

[0015] By adopting the above technical solution, the second pull plate and the vertical rod can prevent the first clamping block from completely separating from the second clamping block when the second clamping plate is no longer clamped by the first clamping plate. This avoids the first clamping block falling to the ground and makes it easier for the staff to fasten the first clamping block and the second clamping block together again, further improving the convenience and practicality of the robot.

[0016] Furthermore, two limiting cylinders are symmetrically fixedly connected to the bottom of the two first clamping blocks, and two rectangular through grooves are symmetrically opened on the outer side walls of the two limiting cylinders. The two liquid outlet pipes are symmetrically and movably inserted into the bottom ends of the two limiting cylinders. The four sets of nozzles are movably connected in the two pairs of rectangular through grooves, and the two hoses are movably inserted into the two limiting cylinders.

[0017] By adopting the above technical solution, the limiting cylinder can prevent the liquid outlet pipe from shaking under the action of the hose, ensuring that the spraying and fertilization work can be carried out smoothly and stably.

[0018] Furthermore, two limiting strips are symmetrically fixedly connected to the top of the horizontal tube, and two limiting grooves are symmetrically opened on the inner top wall of the semi-circular grooves of the two second clamping blocks. The two limiting strips are symmetrically slidably connected in the two limiting grooves.

[0019] By adopting the above technical solution, the first and second clamping blocks can be prevented from rotating back and forth on the horizontal tube, ensuring the stability of the liquid outlet pipe and nozzle position, guaranteeing the stable operation of spraying and fertilizing, and further improving the reliability of the robot.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, two vertical liquid outlet pipes and nozzles connected to them are provided, which can spray the liquid medicine or fertilizer solution evenly from top to bottom onto the stems and leaves of crops. This can ensure that the liquid medicine or fertilizer solution is more evenly distributed on the stems and leaves of crops, thereby enabling crops to absorb the fertility in the fertilizer solution more quickly and fully or enabling the liquid medicine to kill pests and diseases more effectively, thus improving the practicality and reliability of the spraying and fertilizing robot.

[0022] 2. In this application, the fastening mechanism allows the two first pull plates to be pulled in opposite directions until they are positioned on the left and right sides of the two second clamping plates. At this point, the second clamping plates can be detached from the receiving cavity, allowing the first clamping block and the second clamping block to be separated quickly and easily. Conversely, since the corners where the first and second clamping plates are close together are inclined planes with the same inclination, the operator only needs to insert the two pairs of first clamping plates upward into the receiving cavity. Under the action of the inclined plane, the second clamping plates can push open the first clamping plates and move to the upper side of the first clamping plates. In this way, the first clamping plates can fasten the second clamping plates in the receiving cavity, making the connection operation of the first clamping blocks and the second clamping blocks simple and convenient, thus improving the convenience and practicality of the robot.

[0023] 3. In this application, the second pull plate and the vertical rod ensure that when the second clamping plate is no longer clamped by the first clamping plate, the first clamping block will not completely separate from the second clamping block. This prevents the first clamping block from falling to the ground and makes it easier for workers to reconnect the first and second clamping blocks, further improving the convenience and practicality of the robot.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-7 As shown in the embodiment of this application, a greenhouse spraying and fertilizing robot is disclosed, including an outer shell 1. Rollers 11 are installed at the bottom of the outer shell 1. Two pairs of electric telescopic rods 2 are symmetrically fixedly connected to the top of the outer shell 1. A fixing plate 21 is fixedly connected between the output ends of the two pairs of electric telescopic rods 2. A liquid storage tank 3 is fixedly connected to the top of the fixing plate 21. A liquid pump 31 is fixedly connected to the top of the liquid storage tank 3. The input end of the liquid pump 31 is connected to an inlet pipe. The bottom end of the inlet pipe penetrates the top wall of the liquid storage tank 3 and extends to a position close to the inner side wall of the liquid storage tank 3. The output end of the liquid pump 31 is connected to a vertical pipe 32. The top end of the vertical pipe 32 is connected to a horizontal pipe 33. Two vertically distributed outlet pipes 34 are symmetrically connected to the bottom of the horizontal pipe 33. Two sets of nozzles 35 are symmetrically connected to the outer circumferential surface of the outlet pipes 34. A left and right adjustment component 4 is provided on the horizontal pipe 33.

[0034] The left-right adjustment component 4 is used to move the two liquid outlet pipes 34 left and right.

[0035] The side of the storage tank 3 is connected to an inlet pipe for injecting the prepared medicine or fertilizer solution into the storage tank 3;

[0036] The outer casing 1 contains a circuit system and a drive system, both of which are mature existing technologies and will not be described in detail here.

[0037] Specifically, through two vertical liquid outlet pipes 34 and nozzles 35 connected to them, the pesticide or fertilizer solution can be sprayed evenly from top to bottom onto the stems and leaves of crops. This ensures that the pesticide or fertilizer solution is more evenly distributed on the stems and leaves of crops, thereby enabling crops to absorb the nutrients in the fertilizer solution more quickly and fully, or enabling the pesticide solution to kill pests and diseases more effectively, thus improving the practicality and reliability of the spraying and fertilizing robot.

[0038] See Figure 1 , Figure 2 and Figure 6 The left and right adjustment component 4 includes two flexible tubes 41 symmetrically connected to the bottom of the horizontal tube 33. The bottom ends of the two flexible tubes 41 are respectively connected to the top ends of the two liquid outlet tubes 34. The left and right adjustment component 4 also includes two first clamping blocks 42 and two second clamping blocks 43 movably sleeved on the outer circumference of the horizontal tube 33 through semi-circular grooves. The top ends of the two first clamping blocks 42 and the bottom ends of the two second clamping blocks 43 are connected together by a fastening mechanism 44. The two first clamping blocks 42 have two through grooves 421 and two rectangular grooves 422 symmetrically opened on the opposite sides. The bottom ends of the two through grooves 421 are respectively connected to the top ends of the two rectangular grooves 422. The bottom ends of the two flexible tubes 41 pass through the two through grooves 421 and the two rectangular grooves 422 and extend to the lower side of the first clamping block 42. The outer walls of the two flexible tubes 41 are respectively attached to the inner walls of the two rectangular grooves 422 and the inner bottom walls of the two through grooves 421.

[0039] Specifically, by moving the first clamping block 42 left and right along the horizontal tube 33, the liquid outlet pipe 34 can be moved up and down by the hose 41 under the limitation of the inner side wall of the rectangular groove 422 and the inner bottom wall of the through groove 421. This allows adjustment of the left and right positions of the liquid outlet pipe 34 and the nozzle 35, thereby adjusting the position of the nozzle 35 according to the spacing of the crops and the outer diameter of the stems and leaves. This ensures that the nozzle 35 will not collide with the crop stems and leaves or be too far away from them, ensuring that the pesticide or fertilizer solution sprayed by the nozzle 35 can be sprayed onto the crop stems and leaves smoothly and efficiently, reducing the waste of pesticide or fertilizer solution and improving the reliability of the spraying and fertilizing robot.

[0040] See Figure 5 and Figure 7The fastening mechanism 44 includes two pairs of receiving cavities 441 symmetrically opened at the bottom of the second clamping block 43. Two pairs of crossbars 442 are symmetrically and interactively inserted on the left and right sides of the second clamping block 43. Two first pull plates 443 are symmetrically and fixedly connected between the ends of the two pairs of crossbars 442 that are far apart. Two pairs of first elastic members are symmetrically and fixedly connected between the sides of the two first pull plates 443 that are close together and the left and right sides of the second clamping block 43. The ends of the two pairs of crossbars 442 that are close together pass through the left and right side walls of the second clamping block 43 and extend into the two pairs of receiving cavities 441. The ends of the two pairs of crossbars 442 that are close together are symmetrically and fixedly connected. The fastening mechanism 44 includes two pairs of first clamping plates 444 fixedly connected to the top of the first clamping block 42. The top ends of the two pairs of connecting rods 445 are symmetrically fixedly connected to two pairs of second clamping plates 446. The two pairs of second clamping plates 446 can be inserted into the two pairs of receiving cavities 441 and their bottoms are respectively pressed against the tops of the two pairs of first clamping plates 444. The corners where the first clamping plates 444 and the second clamping plates 446 approach each other are inclined surfaces with the same inclination. When the second clamping plate 446 is clamped by the first clamping plate 444, the top surface of the second clamping plate 446 abuts against the inner top wall of the receiving cavity 441.

[0041] Specifically, by simply pulling the two first pull plates 443 in opposite directions until the two first clamping plates 444 are positioned on the left and right sides of the two second clamping plates 446 respectively, the second clamping plates 446 can detach from the receiving cavity 441, allowing the first clamping block 42 and the second clamping block 43 to be quickly and easily separated. Conversely, since the corners where the first clamping plates 444 and the second clamping plates 446 are close together are inclined planes with the same inclination, the operator only needs to insert the two pairs of first clamping plates 444 upward into the receiving cavity 441. Under the action of the inclined plane, the second clamping plate 446 can push open the first clamping plate 444 and move to the upper side of the first clamping plate 444. In this way, the first clamping plate 444 can fasten the second clamping plate 446 into the receiving cavity 441, making the connection operation of the first clamping block 42 and the second clamping block 43 simple and convenient, thus improving the convenience and practicality of the robot.

[0042] See Figures 1-5 The fastening mechanism 44 also includes two pairs of vertical rods 447 that are symmetrically and movably inserted into the top of the second clamping block 43. Two second pull plates 448 are symmetrically and fixedly connected between the top ends of the two pairs of vertical rods 447. Two pairs of second elastic members are symmetrically and fixedly connected between the bottom of the two second pull plates 448 and the top of the second clamping block 43. The bottom ends of the two pairs of vertical rods 447 penetrate the top wall of the second clamping block 43 and extend into the two pairs of receiving cavities 441 respectively and are fixedly connected to the top of the two pairs of second clamping plates 446.

[0043] Specifically, by using the second pull plate 448 and the vertical rod 447, when the second clamping plate 446 is no longer clamped by the first clamping plate 444, the first clamping block 42 will not completely separate from the second clamping block 43. This prevents the first clamping block 42 from falling to the ground, making it easier for workers to reconnect the first clamping block 42 and the second clamping block 43, further improving the convenience and practicality of the robot.

[0044] See Figure 1 and Figure 2 Two limiting cylinders 5 are symmetrically fixedly connected to the bottom of the two first clamping blocks 42. Two rectangular through grooves 51 are symmetrically opened on the outer side wall of the two limiting cylinders 5. Two liquid outlet pipes 34 are symmetrically and movably inserted into the bottom end of the two limiting cylinders 5. Four sets of nozzles 35 are movably connected in the two pairs of rectangular through grooves 51 respectively. Two hoses 41 are movably inserted into the two limiting cylinders 5 respectively.

[0045] Specifically, the limiting cylinder 5 prevents the liquid outlet pipe 34 from shaking under the action of the hose 41, ensuring that the spraying and fertilization work is carried out smoothly and stably.

[0046] See Figures 1-5 Two limiting strips 61 are symmetrically fixedly connected to the top of the horizontal tube 33. Two limiting grooves 62 are symmetrically opened on the inner top wall of the semi-circular groove of the two second clamping blocks 43. The two limiting strips 61 are symmetrically slidably connected in the two limiting grooves 62.

[0047] Specifically, it can prevent the first clamping block 42 and the second clamping block 43 from rotating back and forth on the horizontal tube 33, ensuring the stability of the position of the liquid outlet tube 34 and the nozzle 35, ensuring the stable operation of spraying and fertilizing, and further improving the reliability of the robot.

[0048] Working principle: Based on the spacing and stem and leaf outer diameter of the crops to be sprayed or fertilized in the greenhouse, the first clamping block 42 and the second clamping block 43 are moved left and right along the horizontal pipe 33. This adjusts the position of the liquid outlet pipe 34 and the nozzle 35, ensuring that the nozzle 35 does not collide with the crop stems and leaves or is too far away from them. This ensures that the pesticide or fertilizer solution sprayed from the nozzle 35 is fully and smoothly sprayed onto the crop stems and leaves, reducing waste of pesticide or fertilizer solution and improving the reliability of the spraying and fertilizing robot.

[0049] Then, simply insert the two pairs of first clamping plates 444 upward into the receiving cavity 441. Under the action of the inclined plane, the second clamping plate 446 can push open the first clamping plate 444 and move to the upper side of the first clamping plate 444. In this way, the first clamping plate 444 can fasten the second clamping plate 446 into the receiving cavity 441, so that the first clamping block 42 and the second clamping block 43 can be easily connected together and clamped on the outer circumferential surface of the horizontal tube 33. In this way, the position of the nozzle 35 can be fixed.

[0050] Then, the robot is driven by the roller 11 to walk inside the greenhouse. At the same time, the liquid pump 31 is activated to draw out the liquid medicine or fertilizer solution from the storage tank 3 and spray it onto the stems and leaves of the crops through the vertical pipe 32, horizontal pipe 33, liquid outlet pipe 34 and nozzle 35 to complete the spraying and fertilization work.

[0051] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
