[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Embodiment 1:

[0041] Reference Figure 1-Figure 13 The present invention provides a multifunctional farmland management and inspection agricultural machine, comprising:

[0042] A gantry body 1, wherein the four bottom corners of the gantry body 1 are rotatably connected with self-propelled wheels 2, and a steering control assembly is provided between the four sets of self-propelled wheels 2 and the top bracket of the gantry body 1, and the steering control assembly is used to adjust the angle between the four sets of self-propelled wheels 2 and the gantry body 1, so that the gantry body 1 can rotate around the central axis of the gantry body 1;

[0043] Functional mechanism, the functional mechanism includes inspection component, raking component and spraying component;

[0044] Two sets of locking shells 9 are arranged on the top of the gantry body 1. The locking shells 9 are used to make the inspection component detachably connected to the top of the gantry body 1, or to make the spraying component detachably connected to the top and side wall of the gantry body 1, or to make the raking component detachably connected below the top of the gantry body 1.

[0045] The main function of the gantry body 1 is to use the gantry structure to allow a space of sufficient height to be avoided under the body, so that the gantry body 1 can avoid damaging the crops when walking in the farmland; the main function of the steering control component is to control the four sets of self-propelled wheels 2 to move in the forward direction at the same time or adjust the four sets of self-propelled wheels 2 to turn at the same time, so that the movement direction of the four sets of self-propelled wheels 2 is on a pitch circle, realizing the on-the-spot steering of the gantry body 1, which is more suitable for movement in a small range; the main function of the locking shell 9 is to fix the inspection component on the gantry body 1 to realize the inspection function of the farmland or the greenhouse, or to fix the harrowing component under the gantry body 1 to harrow the ground, or to fix the spraying component on the gantry body 1 to sprinkle water or spray medicine. On the whole, the present invention realizes the flexible movement of the gantry body by providing a gantry body and self-propelled wheels that always turn on the same pitch circle. The gantry body can be moved to most positions in the farmland or greenhouse without damaging the crops. At the same time, by providing a locking shell structure, the gantry body can be flexibly equipped with inspection components, harrowing components or spraying components, etc., to realize multifunctional farmland management or inspection.

[0046] According to a further optimization scheme, the four corners of the gantry body 1 are respectively vertically fixedly connected with a rotating shaft sleeve 7, a rotating shaft is rotatably connected inside the rotating shaft sleeve 7, the bottom end of the rotating shaft is fixedly connected to the self-propelled wheel 2, and the top end of the rotating shaft is transmission-connected to the steering control assembly.

[0047] Further optimization scheme, such as Figure 1 As shown, an equipment box 3 is fixedly connected to the bottom of the side wall of the gantry body 1, and the main function of the equipment box 3 is to contain batteries and control equipment.

[0048] To further optimize the solution, the self-propelled wheel 2 can be equipped with a wheel hub motor to realize autonomous rotation. At the same time, the size of the self-propelled wheel 2 is appropriately selected according to the farmland conditions to ensure that the agricultural implement has good passability when moving in the farmland.

[0049] A further optimized solution is that the steering control assembly includes a steering control shell 4 fixedly connected to the top of the gantry body 1, and two groups of slide plates 14 are slidably connected in the steering control shell 4 from front to back along the traveling direction of the gantry body 1, and one end of a pull rod 5 is hinged on the left and right sides of the two slide plates 14, and the other end of the pull rod 5 passes through the side wall of the steering control shell 4 and is hinged to one end of a rocker arm 6, and the other ends of the four rocker arms 6 are fixedly connected to the tops of the four rotating shafts, and a steering drive component is arranged between the two slide plates 14 and the steering control shell 4.

[0050] A further optimized solution is that the steering drive component includes a first bidirectional screw rod 13 connected to the steering control housing 4 and rotating along the travel direction of the gantry body 1, and the tops of the two slide plates 14 are respectively fixedly connected with threaded sleeves 15, and the two threaded sleeves 15 are respectively transmission-connected to the two ends of the first bidirectional screw rod 13, and one end of the first bidirectional screw rod 13 is transmission-connected with the first motor 12, and the first motor 12 is fixedly connected in the steering control housing 4.

[0051] like Figure 1 and Figure 3 As shown, when moving forward or backward, the four groups of self-propelled wheels 2 are in a parallel state. When turning is required, the control device controls the first motor 12 to drive the first bidirectional screw 13 to rotate, so that the threaded sleeve 15 moves to both sides of the first bidirectional screw 13 under the action of the thread transmission, and then drives the two groups of slides 14 to move to both sides of the first bidirectional screw 13. When the two slides 14 move, they simultaneously push the four groups of pull rods 5, so that the pull rods 5 push the swing rod 6 outward, thereby realizing the coordinated rotation of the four groups of self-propelled wheels 2. At this time, the control device controls the self-propelled wheels 2 on the left and right sides to rotate in opposite directions respectively, so as to realize the in-situ turning of the gantry body 1. When it is necessary to resume straight-line travel, the control device controls the first motor 12 to rotate in the opposite direction to reset the slide 14.

[0052] According to a further optimized solution, a reinforcing plate 8 is horizontally fixedly connected to the top of the gantry body 1, and two locking shells 9 are horizontally fixedly connected to both sides of the reinforcing plate 8;

[0053] The front and rear ends of the top of the locking shell 9 are respectively provided with top installation slots 16 facing downward, and the front and rear ends of the bottom of the locking shell 9 are respectively provided with bottom installation slots 18 facing upward, and the two bottom installation slots 18 are located on the outside of the two top installation slots 16, and the side installation slots 17 are provided on the side wall of the locking shell 9, and the side installation slots 17 are connected with the two bottom installation slots 18, and the tops of the left and right sides of the gantry body 1 are respectively provided with side sockets 10, and the side sockets 10 are correspondingly arranged with the side installation slots 17.

[0054] A further optimized solution is that the inner side of the locking shell 9 is rotatably connected to a second bidirectional screw rod 22 along the length direction of the locking shell 9, and both ends of the second bidirectional screw rod 22 are respectively threaded with a plug 23, and the plug 23 is horizontally slidably connected in the locking shell 9 through a limit piece, and through holes 24 are respectively opened on the two side walls of the top installation slot 16 and the bottom installation slot 18, and the plug 23 and the through holes 24 are correspondingly arranged, and a rotating drive member is arranged between the second bidirectional screw rod 22 and the locking shell 9.

[0055] According to a further optimized solution, the rotating driving member includes a second motor 19 fixedly connected in the locking shell 9, the output shaft of the second motor 19 is fixedly sleeved with a gear 20, the middle fixed sleeve of the second bidirectional screw 22 is provided with a gear ring 21, and the gear ring 21 is transmission-connected to the gear 20.

[0056] For further optimization, the limit member can be equipped with a limit block (not shown in the figure) fixedly connected to the side wall of the insert tube 23 and close to one end of the gear ring 21, and a slide groove (not shown in the figure) horizontally opened in the locking shell 9, and the limit block is slidably connected in the slide groove.

[0057] like Figure 6 As shown, the control device drives the gear 20 to rotate by controlling the second motor 19, and then drives the second bidirectional screw 22 to rotate by driving the gear ring 21. Since the cannula 23 can only move horizontally through the limiter, the second bidirectional screw 22 drives the cannula 23 at both ends to pass through the bottom installation slot 18 and the top installation slot 16 in sequence through the perforation 24. The cannula 23 can be withdrawn by controlling the second motor 19 to reverse.

[0058] To further optimize the solution, the inspection component and the spraying component are respectively provided with top connecting pieces for fixed connection to the top of the gantry body 1;

[0059] The top connecting member includes a top connecting plate 25, which abuts against the top of the gantry body 1. Four groups of connecting rods 26 are vertically fixedly connected to the bottom of the top connecting plate 25. The four groups of connecting rods 26 are respectively adapted to the four groups of top installation slots 16. The four groups of connecting rods 26 are provided with a first through slot, and the insert 23 passes through the first through slot to fix the connecting rod 26 in the top installation slot 16.

[0060] like Figure 7 and Fig.11 As shown, when inspection in the farmland or greenhouse is required, the operator places the top connecting plate 25 on the top of the gantry body 1, and inserts the four groups of connecting rods 26 into the four groups of top installation slots 16, and then controls the second motor 19 to rotate, so that the insert tube 23 passes through the through hole 24 and the first through slot, and locks the connecting rod 26 in the top installation slot 16 to achieve connection.

[0061] Further optimization scheme, such as Fig.11 As shown, the inspection component includes a rotating rod 27 vertically fixedly connected to the top connecting plate 25, and the top of the rotating rod 27 is fixedly connected to a multi-spectral sensor 28 and an image sensor 29, which are respectively used to obtain multi-spectral images of farmland plants in different bands and multi-angle videos and photographs of farmland plants.

[0062] Similarly, if Figure 8 and Fig.13 As shown, the spraying assembly includes a liquid tank 30 and a liquid pump fixedly connected to another top connecting plate 25. The liquid tank 30 is used to store water or pesticides. It also includes a spraying pipe 33, which is horizontally fixedly connected to the end of the connecting block 32 away from the side insertion rod 31. The liquid pump pumps the liquid in the liquid tank 30 to the spraying pipe 33, thereby achieving spraying on the farmland.

[0063] To further optimize the solution, the spray assembly is also provided with a side connection piece for fixedly connecting to the side wall of the gantry body 1;

[0064] The side connecting member includes a connecting block 32, one side of which is fixedly connected to one end of two sets of side plug rods 31, the other end of the side plug rod 31 passes through the side plug hole 10, the side installation slot 17 and is adapted to the bottom installation slot 18, and a second through slot is opened at one end of the side plug rod 31 away from the connecting block 32, and the insert pipe 23 passes through the second through slot to fix the side plug rod 31 in the bottom installation slot 18.

[0065] like Figure 8 and Fig.13 As shown, when it is necessary to spray pesticides or water, the operator first fixes the top connecting plate 25 with the liquid tank 30 to the top of the gantry body 1, and then inserts the side insertion rod 31 through the side insertion hole 10 and the side installation slot 17 on the left and right sides of the gantry body 1, so that the side insertion rod 31 is in the bottom installation slot 18. After that, the control device controls the second motor 19 to rotate, so that the insertion tube 23 passes through the through hole 24 and the first through slot and the second through slot in turn, locks the connecting rod 26 in the top installation slot 16, and locks the side insertion rod 31 in the bottom installation slot 18 to achieve connection.

[0066] In a further optimized solution, the raking assembly is provided with a bottom connecting piece for fixedly connecting to the bottom of the top of the gantry body 1;

[0067] The bottom connecting member includes a bottom connecting plate 34, and four groups of bottom connecting rods 35 are vertically fixedly connected to the top of the top connecting plate 25. The four groups of bottom connecting rods 35 are respectively adapted to the four groups of bottom installation slots 18. A third through slot is opened on the four groups of bottom connecting rods 35, and the insert 23 passes through the third through slot to fix the bottom connecting rod 35 in the bottom installation slot 18.

[0068] like Fig. 9 and Fig.12 As shown, when it is necessary to harrow the ground, the operator places the bottom connecting plate 34 under the top of the gantry body 1, and inserts the four groups of bottom connecting rods 35 into the four groups of bottom installation slots 18, and then controls the second motor 19 to rotate, so that the insertion tube 23 passes through the through hole 24 and the third through slot, and locks the bottom connecting rod 35 in the bottom installation slot 18 to achieve connection.

[0069] Further optimizing scheme, the raking assembly includes a sled 36, and one end of the sled 36 away from the working end is hinged below the bottom connecting plate 34. An electric telescopic rod (not shown in the figure) for adjusting the height of the sled 36 is provided between the sled 36 and the bottom connecting plate 34.

[0070] Embodiment 2:

[0071] The only difference between this embodiment and the first embodiment is that the end of the insert tube 23 away from the second bidirectional screw rod 22 is set as a conical surface, and a plurality of spring seat assemblies 11 are fixedly connected to the top of the gantry body 1, the side wall of the gantry body 1 and the bottom wall below the top of the gantry body 1.

[0072] According to a further optimized solution, the spring seat assembly 11 fixedly connected to the side wall of the gantry body 1 is located between the insertion holes 10 on both sides.

[0073] According to a further optimized solution, the spring seat assembly 11 includes a seat body 111 , and a side wall of the seat body 111 away from the gantry body 1 is slidably connected with an abutment block 112 , and a side wall of the abutment block 112 close to the seat body 111 is abutted against the seat body 111 by a plurality of springs 113 .

[0074] like Figure 6 , Fig.10 and Fig.11 As shown, if the inspection assembly needs to be installed, the operator first inserts the connecting rod 26 into the top installation slot 16. At this time, the top connecting plate 25 abuts against a plurality of abutment blocks 112 located at the top of the gantry body 1. At this time, the first through slot and the through hole 24 are in a non-concentric state. After that, the second motor 19 is controlled to rotate to make the insert 23 pass through. Due to the setting of the conical surface, the insert 23 will pass through the through hole 24 and slide with the first through slot, pulling the connecting rod 26 into the top installation slot 16, so that the top connecting plate 25 compresses the spring 113, thereby avoiding the problem of loose connection between the top connecting plate 25 and the gantry body 1.

[0075] The process of connecting the spraying assembly and the harrowing assembly is similar and will not be described in detail here.

[0076] Embodiment three:

[0077] The difference between this embodiment and the first embodiment is that Fig.14 As shown, the top of another top connecting plate 25 can be fixedly connected to the transport bucket 37. The top connecting plate 25 fixedly connected with the transport bucket 37 is fixed to the top of the gantry vehicle body 1, so that the auxiliary transportation of articles can be realized, the labor is reduced, and the work efficiency is improved.
