Description

A kind of flexible flexible belt convenient sending and receiving device

technical field

The invention relates to the field of hose soft belts such as soft fire-fighting water pipes and farmland irrigation water pipes, in particular to a convenient sending and receiving device for soft hose belts.

Background technique

At present, the existing flexible hose flexible belt convenient sending and receiving device mainly introduces the sending and receiving device of the cylindrical soft water pipe, and most of the devices tend to be portable and other convenient methods; Hose, because there is a certain amount of water in the water pipe when the water pipe is collected, the water pipe is long, the diameter of the coil is large, and the weight is heavy, it is not suitable for hand-held operation at all, and the patents and applications for this type of water pipe are limited to manual power or mechanical The power source is in a fixed position, and it is not easy to remove and install, and the friction and practicality of the water pipe are not considered well. Therefore, it is necessary for us to design a more practical device to solve this problem, and improve work efficiency through the device.

Contents of the invention

The object of the present invention is to provide a flexible hose flexible belt convenient sending and receiving device to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A flexible hose and soft belt convenient sending and receiving device, including a main frame, a support frame, a driving motor group, a driving wheel, a reel, a conversion bracket, a control system, and a battery pack; the driving motor group is fixed on the main frame, and the driving motor group It is fixed at the rear of the main frame. On the one hand, it will not scratch the flexible hose belt due to the friction between the volume and the soft hose belt; on the other hand, it is located at the rear, and the center of gravity moves backward. That is, the center of gravity of the main frame is balanced; the drive motor unit adopts a single-axis motor and is radially connected to the reducer. After the reducer, the high-speed and small torque is transformed into low-speed and high-torque, so a smaller-sized DC motor can be used as the power source .

The bottom of the main frame is provided with a conversion bracket, and the conversion bracket is symmetrically distributed in the left and right; the driven wheel and the ski board are arranged on the conversion bracket, and the driven wheel and the ski board form a fixed structure with the conversion bracket concave slot in the middle; for some places, For example, the farmland and paddy fields after irrigation are wet and soft. The tires will slip or stick to the soil and cannot move forward. This will not only increase the forward resistance, but also cause secondary damage to the grown seedlings. The sled board has a large force-bearing area and a small pressure per unit area, which is especially suitable for wet and soft soil. Little damage is done to the young seedlings. In conditions where the road surface is relatively hard, the ski board is obviously not suitable, so the conversion bracket can be switched between the two soil surface conditions. The switching method is simple and practical: the concave card slot of the conversion bracket on the conversion bracket is connected to the main frame through a spring, the spring only plays a role of tension, and the concave and convex matching between the concave card slot of the conversion bracket and the main frame plays a fixed role . Therefore, the conversion bracket only needs to manually pull out the concave-convex matching of the conversion bracket and rotate it 180 degrees.

The main frame at the bottom contains a positioning column, a spring, and a grating ruler; a T-shaped groove is opened on the inner surface of the bottom end of the main frame, and the notches face each other. There are two positioning columns in the T-shaped slot, which are fixed inside the main frame and parallel to the main frame. The cylindrical surface at the bottom of the positioning column is welded to the bottom cross-section of the main frame to fix the bottom, and the cylindrical surface at the top of the positioning column passes through the T-slot of the main frame. The upper cross-section is welded to fix the upper part, and a spring and a symmetrical movable frame matched with the positioning column are placed on the positioning column, and the spring is above the symmetrical movable frame. The elastic force of the spring will make the symmetrical movable frame be at the bottom of the T-shaped groove of the main frame. The outer end of the main frame of the symmetrical movable frame is fixed with the tapered hole bearing at one end of the reel, and the outer end of the main frame of the symmetrical movable frame is fixed with the transmission bearing of the reel on the other side; the inner side of the main frame of the symmetrical movable frame has a grating pointer, which moves symmetrically The movement of the frame up and down will move on the grating scale, so as to know the specific position of the reel. The grating ruler in the main frame is connected to the control system, so that the control system can make a judgment based on the position of the reel.

The drive motor unit is hinged to the reel through a chain; the chain is easily deformed and has less toughness than the transmission belt, so the force on the pinch roller is smaller, which is convenient for installation and maintenance. The chain can work under the conditions of low speed, heavy load and high temperature and dusty conditions, and can ensure accurate transmission ratio, high transmission power, and small force acting on the shaft, so that it can complete the task of transmission torque . The pinch wheel shaft is connected to the main frame, and a torsion spring is installed on the fixed rotating shaft between the main frame and the pinch wheel, so that the pinch wheel can pick up the chain, so that the chain is in a tight state throughout the whole process when the position of the reel changes.

The approximate position of the reel and the reel drive bearing is fixed by the concave-convex slot, and the specific position is locked by the fixed pin; the reel can be moved by pulling out the fixed pin, and the concave-convex slot can withstand the large torque required by the reel. The driving driven wheel, concave-convex slotted holes and fixed pin slotted holes are arranged on the reel transmission bearing. One end of the tapered reel is positioned in cooperation with the tapered hole on the shaft at the bottom end of the main frame.

There are two supporting frames, the main supporting frame is fixed on the driving wheel and the main frame, one end of the auxiliary supporting frame is fixed with the driving wheel, and the other end can be fixed by the connecting beam of the main frame; the position of the connecting beam of the auxiliary supporting frame will change The pitch angle of the main frame is suitable for operation by people of different heights and ages. At the same time, the smaller the pitch angle of the main frame from the ground, the lower the center of gravity will make the weight tend to the driving wheel, which is convenient for moving forward. The larger the pitch angle of the main frame from the ground, the higher the height of the main frame, which is helpful for driving water when there is water in the water pipe.

There is a flexible shaft on the connecting beam of the main frame; the function of the flexible shaft has two points. Compared with the fixed circular tube, the rotating shaft, the rotational friction of the flexible shaft is small, and the resistance brought to the driving motor unit will be correspondingly reduced; The shape of the shaft can be changed, which is very helpful for correcting the position of the flexible hose belt and correcting the position of the flexible hose reel.

A rotating shaft is fixed below the drive motor unit to prevent friction between the flexible hose belt and the drive motor unit; Unit casing. Therefore, installing the rotating shaft on the drive motor unit can improve the friction, reduce the resistance of the reel, and will not damage the soft belt of the hose.

The control system is connected to sensor signal output ports such as grating ruler and grating ruler pointer; connected to switch, throttle handle and other mode selection signal output ports; connected to the control port of the driving wheel and the drive motor with the drive function module; thus making the above collocations form control closed loop.

As a further solution of the present invention: the left handle of the main frame is provided with a mode selection switch, one mode is the automatic pace mode, and the other is the full power mode;

As a further solution of the present invention: the right handle of the main frame is provided with a direction selection switch, one for forward and one for backward; the specific position and specific shape of the mode selection switch and direction selection switch are not set.

As a further solution of the present invention: the right handle of the main frame is provided with an accelerator handle; the specific position and specific shape of the accelerator handle on the handle are not set.

As a further solution of the present invention: the control system can adopt single-chip microcomputer, PLC, DSP, etc., which have calculation, storage, and judgment and are not limited to smart chips of this type; the internal circuits of the control system include chips, decoding chips, encoding chips, Music chips, voice chips, language chips, or sound memory chips, or one or more chips among other functional chips;

Compared with the prior art, the beneficial effect of the present invention is: the flexible hose soft belt convenient transceiver device selects functions such as automatic pace mode, full power mode, forward direction, backward direction, speed selection, etc. through manual setting, and the above functions can be freely controlled. Combination of hose soft belt convenient collection, coiling, laying and other functions, so as to save manpower and improve work efficiency.
