Description

Technical Field

[0001] The present invention relates to the field of sprinkler irrigation machines, and in particular to a device for a sprinkler irrigation machine guide control system. Background Art

[0002] A sprinkler is a machine used to spray irrigation water. It typically includes a pump unit, pipes, sprinkler heads, and a travel mechanism. A sprinkler is a unitized sprinkler system.

[0003] In existing related technologies, a translatory sprinkler system consists of branch pipes, sprinkler heads, travel wheels, and a truss, moving perpendicular to the branch pipes. Like the clockwise sprinkler system, the branch pipes are supported on a self-propelled truss. However, the truss moves in a straight line, spraying as it moves. This sprinkler system is supplied with water from an open channel perpendicular to the branch pipes, or alternatively, from a hose. However, a major drawback of translatory sprinklers is that they can only move linearly perpendicular to the branch pipes during spraying, not longitudinally, and cannot rotate between adjacent towers. Therefore, translatory sprinklers must be equipped with a guide device during operation.

[0004] Currently, conventional guidance devices include GPS and other guidance equipment. Although they have high guidance accuracy, they require the configuration of corresponding computing and processing equipment. Similarly, the precision requirements of control devices such as the drive motor used to drive the sprinkler are also relatively high, and the overall cost of use is high.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art is the subject of the present invention. Summary of the Invention

[0006] In order to solve the above problems, the present invention discloses a device for a sprinkler guidance control system.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: a device for a sprinkler guide control system, comprising a guide tube and a sliding guide assembly provided on the guide tube, the sliding guide assembly being used to be connected to a frame of the sprinkler, the sliding guide assembly comprising two side plates, the top ends of the two side plates being connected by a hinge structure, a positioning groove for being snapped into the guide tube is formed between the lower ends of the two side plates, a cross bar is provided at the upper end of the positioning groove along its length direction, a pair of sliding support rods are respectively provided at the front and rear ends of the cross bar, a first limiting roller is installed at the lower ends of the pair of sliding support rods at intervals, the first limiting roller is used to engage with the top surface of the guide tube in rolling contact;

[0008] Second limiting rollers are respectively installed at the front and rear ends of the side plate, and the second limiting rollers are used for rolling contact with the side surfaces of the guide tube.

[0009] In the above solution, the inner ends of the pair of sliding support rods are arranged to gradually approach each other from the outside to the inside.

[0010] In the above scheme, the end of the cross bar is connected to a sleeve, and the sliding support rod is inserted into the sleeve, thereby forming a sliding fit between the sliding support rod and the cross bar. The sliding support rod is provided with multiple threaded holes along its length direction, and the sleeve and the threaded holes of the sliding support rod are detachably connected by bolts.

[0011] In the above scheme, a clamping mechanism is provided at the top end between the two side plates, and the clamping mechanism includes an electric cylinder and a push block, which are respectively arranged on the two side plates. The push rod of the electric cylinder is rotatably connected to the push block, and the other end of the electric cylinder is rotatably connected to the side plate.

[0012] In the above solution, the first limiting roller and the second limiting roller are both hollow tires, a circle of rubber flexible magnets is arranged on the inner side of the tires of the first limiting roller and the second limiting roller, and electromagnets are installed on the hubs of the first limiting roller and the second limiting roller.

[0013] In the above solution, a plurality of electromagnets are provided, and the plurality of electromagnets are arranged in a ring shape at the center of the hubs of the first limiting roller and the second limiting roller.

[0014] In the above solution, a plurality of elastic limiting blocks are arranged inside the rubber flexible magnets of the first limiting roller and the second limiting roller, and the plurality of elastic limiting blocks are arranged in a ring shape inside the rubber flexible magnet.

[0015] In the above solution, the second limiting rollers on the two side panels are both arranged horizontally.

[0016] In the above scheme, two forces are formed between the rubber flexible magnets in the first limiting roller and the second limiting roller and the electromagnet: mutual repulsion and attraction, respectively. The two forces are achieved by changing the magnetic poles of the electromagnet; when the first limiting roller and the second limiting roller pass through the guide pipe joint, the electromagnets in the first limiting roller and the second limiting roller located on the diagonal line and the rubber flexible magnets attract each other to reduce the tire diameter.

[0017] The cam is secured to the top of the machine and has two camshafts that are adapted to move along the guide rails, the cam being secured to the top of the machine and allowing the cam to move relative to the guide rails when the cam is in motion. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further explained below with reference to specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0024] Example 1: See Figure 1-3 A device for a sprinkler guide control system, which is applied to a small-sized translation sprinkler; it comprises a guide tube 100 and a sliding guide assembly 200 provided on the guide tube 100, see Figure 5During operation, the guide tube 100 is set parallel to the course of the sprinkler 300. A guide tube 100 and a corresponding sliding guide assembly 200 are respectively arranged at both ends of the sprinkler 300. The sprinkler 300 body can be towed by a traction rope set at the end of the course, such as the traction rope of an electric winch. The sliding guide assembly 200 is used to connect to the frame of the sprinkler 300. The specific connection is to achieve rotational connection through bearings. The guide tube 100 can be made of a metal tube or a thicker PVC tube.

[0025] The sliding guide assembly 200 specifically includes two side plates 201. The top ends of the two side plates 201 are connected by a hinge structure. A positioning groove 202 for inserting into the guide tube 100 is formed between the lower ends of the two side plates 201. The two side plates 201 can rotate relative to each other. During installation, the guide tube 100 is inserted into the positioning groove 202 by separating the two side plates 201.

[0026] The upper end of the positioning groove 202 is provided with a cross bar 203 along its length direction, and the front and rear ends of the cross bar 203 are respectively provided with a pair of sliding support rods 204, and the lower ends of the pair of sliding support rods 204 are spaced apart and installed with first limiting rollers 205, which are used to roll and contact with the top surface of the guide tube 100; during operation, the two first limiting rollers 205 are arranged on the left and right sides of the middle of the top of the guide tube 100, and limit its shaking in the left and right directions through the action of friction; in this embodiment, the inner ends of the pair of sliding support rods 204 are gradually approached from the outside to the inside, and the first limiting rollers 205 act on the guide tube 100 at a certain angle. On the one hand, there is friction between the two, and on the other hand, there is a component force in the inclined direction. The superposition of the two makes it less likely to produce position deviation during its movement;

[0027] At the same time, second limiting rollers 206 are respectively installed at the front and rear ends of the side plates 201. The second limiting rollers 206 are used to roll with the side surfaces of the guide tubes 100. The second limiting rollers 206 can limit the lower ends of the side plates 201. Preferably, the second limiting rollers 206 on the two side plates 201 are both arranged horizontally. The friction between the treads of the second limiting rollers 206 and the guide tubes 100 further limits the vertical displacement of the side plates 201, making the sliding guide more precise.

[0028] During use, guidance is performed by relying on the placement of the guide tube 100. The sliding guide assembly 200 can be stably clamped on the guide tube 100 to guide the sprinkler. Compared with traditional guidance methods such as GPS, the mechanical guidance method does not require corresponding GPS computing and processing equipment and GPS position correction systems, as well as more accurate angle control devices for the drive wheel group. For example, in order to maintain accurate angle adjustment of the drive wheel group, a stepper motor or a servo motor is usually required as the drive motor. The overall structure of this solution is simpler and the cost is lower.

[0029] Example 2: See Figure 1-3 The guide rod 204 is provided with a plurality of threaded holes along its length, and the sleeve 207 is provided with a plurality of threaded holes along its length. The sleeve 207 and the threaded holes of the sliding support rod 204 are detachably connected by bolts. Specifically, a long slot or a plurality of connecting holes can be provided on the sliding support rod 204 along its length, and bolts are provided between the long slot or the connecting hole and the threaded hole to lock and fix it. By changing the different positions of the bolts in the long slot or different connecting holes, the extension length of the first limiting roller 205 at the lower end of the sliding support rod 204 can be adjusted to adapt to guide tubes 100 of different diameters.

[0030] Example 3: See Figure 1-3 , which is different from Example 1, is that a clamping mechanism is further provided at the top between the two side plates 201, and the clamping mechanism includes an electric cylinder 208 and a push block 209, which are respectively arranged on the two side plates 201, and the push rod of the electric cylinder 208 is rotatably connected to the push block 209, and the other end of the electric cylinder 208 is rotatably connected to the side plate 201; the electric cylinder 208 spans between the two side plates 201. During operation, by opening the electric cylinder 208 and extending its push rod, the two side plates 201 can be further clamped against the guide tube 100 to make them more stable.

[0031] Example 4: See Figure 4 The first limiting roller 205 and the second limiting roller 206 are both hollow tires. A circle of rubber flexible magnets 210 is arranged on the inner side of the tires of the first limiting roller 205 and the second limiting roller 206. Electromagnets 211 are installed on the hubs of the first limiting roller 205 and the second limiting roller 206.

[0032] When the guide tubes 100 are long, flanges are used to connect the guide tubes 100, and the flanges usually partially protrude from the guide tubes 100. To facilitate the smooth passage of the sliding guide assembly 200, two forces are further divided between the rubber flexible magnet 210 in the first limiting roller 205 and the second limiting roller 206 and the electromagnet 211: mutual repulsion and attraction, respectively. The two forces are achieved by changing the magnetic poles of the electromagnet 211. The magnetic poles of the rubber flexible magnet 210 are fixed, while the magnetic poles of the electromagnet 211 are achieved by changing the direction of current. The rubber flexible magnet 210 is an existing functional composite material made of rubber or thermoplastic elastomer as a matrix and magnetic solid powder. The electromagnet 211 is powered by a conductive slip ring during its rotation.

[0033] When the first limiting roller 205 and the second limiting roller 206 pass through the joint flange of the guide tube 100, the electromagnets 211 and the rubber flexible magnets 210 in the first limiting roller 205 and the second limiting roller 206 located on the diagonal line attract each other to reduce their tire diameters to facilitate their passage through the joint flange; by changing the tire diameters at the diagonal line, the diameters of the two tires on the same side are avoided from shrinking at the same time, and the force of the guide tube 100 is reduced synchronously, resulting in the possibility of the overall deviation to that side.

[0034] There are multiple electromagnets 211 in the roller 206, and the multiple electromagnets 211 are arranged in a ring shape at the center of the hub of the first limiting roller 205 and the second limiting roller 206, so that the electromagnets 211 can act evenly on the circumference of the rubber flexible magnet 210.

[0035] In order to avoid excessive deformation of the rubber flexible magnet 210 of the first limiting roller 205 and the second limiting roller 206 and causing damage to the electromagnet 211 when they interact with each other, a plurality of elastic limiting blocks 212 are further arranged on the inner side of the rubber flexible magnet 210 of the first limiting roller 205 and the second limiting roller 206. The plurality of elastic limiting blocks 212 are arranged in a ring shape on the inner side of the rubber flexible magnet 210. The elastic limiting blocks 212 can be made of polyurethane foam. The elastic limiting blocks 212 are located between the rubber flexible magnet 210 and the electromagnet 211, which can prevent the two from being completely adsorbed together and causing large deformation.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
