Description

Crawler transporter

This invention is related to a conveyor, especially a single crawler conveyor driven by a wheel hub motor, and provides a crawler conveyor structure with a light structure, a stable center of gravity and low kinetic energy loss.

According to the agricultural operations such as gardening, farmland cultivation, orchard planting, etc., crawler conveyors are widely used by agricultural practitioners because they can adapt to the rugged terrain environments such as soil, mud, gravel, etc. commonly seen in farmlands, orchards, and gardening with crawler transmission.

At present, crawler conveyors are equipped with double crawlers under the transport platform. For ridges, farmlands and orchards with small planting distances, the double crawler conveyors cannot enter due to their large width. They can only be parked outside farmlands and orchards, which is inconvenient to use. Crawler conveyors generally use engines to drive the crawlers, and the engine-driven method requires an additional gearbox, which increases the overall weight of the transporter and makes it laborious and difficult for personnel to operate. Although the engine speed reduction through the gearbox meets the use requirements, the multiple transmission speed reductions greatly consume power. When transporting a large amount of crops, there will be insufficient power, which reduces the transportation efficiency.

In view of this, how to solve the above problems is the primary topic that this creation wants to solve.

The main purpose of this invention is to provide a crawler conveyor that adopts a single crawler power mechanism and a wheel hub motor as a power source, so that the power source and the power drive mechanism form an integral whole, reducing the overall weight of the crawler conveyor, and having the effects of strong power, light weight, and flexible operation.

Figure 1 is a three-dimensional diagram of the crawler conveyor of this creation; Figure 2 is a schematic diagram of the transmission unit structure of the crawler conveyor of this creation; Figure 3 is a schematic diagram of the frame pivot lifting structure of the crawler conveyor of this creation; Figure 4 is a schematic diagram of the frame pivot reset structure of the crawler conveyor of this creation.

As shown in Figure 1, the crawler conveyor provided by the present invention includes a vehicle body unit 1, a transmission unit 2 and a control unit 3.

The vehicle body unit 1 includes a frame 11, and handles 12 extending upward and backward are symmetrically provided on opposite sides of the frame 11, and a mounting frame 13 is provided between the two handles 12. The opposite sides of the frame 11 extend vertically downward to the bottom of the frame and are connected to an auxiliary wheel 14. The frame 11 also has a supporting plate 111, and a supporting seat 112 extending downward is provided on the bottom surface of the supporting plate 111. A plurality of side baffles 113 arranged in a circular shape are provided on the supporting plate 111. The plurality of side baffles 113 surround a carrying space for placing crops, fertilizers, seedlings, etc. to be transported, and the side baffles 113 can be used to prevent items from falling during transportation.

Please refer to Figure 2. The transmission unit 2 has a base 21 disposed below the frame 11 and pivoted with the support seat 112, so that the frame 11 can pivot forward and backward with the support seat 112 as an axis. To prevent the support seat 112 from hitting the base 21 and causing damage to the parts when the frame 11 pivots, the upper surface of the base 21 abutting against the support seat 112 is provided with an anti-collision unit 25 adapted to the bottom of the support seat 112. The anti-collision unit 25 can be made of a material with a buffering effect such as rubber cotton or foam cotton. Please refer to Figures 3 and 4. When the crawler conveyor is driving downhill, the frame 11 pivots backward with the support seat 112 as the axis, so that the frame remains horizontal when driving downhill; when driving on flat ground, the frame 11 pivots forward until the base 21 hits the anti-collision unit 25, so that the frame remains relatively horizontal. In this way, the crawler conveyor can maintain the frame 11 horizontally according to different terrains to prevent goods from falling.

Please continue to refer to Figures 1 and 2. A driving wheel 22 is pivoted on one side of the base 21, and a transmission wheel 23 is pivoted on the base 21 in front of the driving wheel 22, and a transmission track 24 that can link the driving wheel 22 and the transmission wheel 23. The transmission unit 2 and the symmetrically arranged auxiliary wheel 14 form a stable triangular support structure, making the crawler conveyor more stable during the movement and not easy to tip over. The outer diameter of the driving wheel 22 is larger than the outer diameter of the transmission wheel 23. When the driving wheel 22 is at a lower speed, the transmission track 24 can drive the driving wheel 23 to rotate, making it easier to drive and start.

As shown in FIG. 1 , the driving wheel 22 is composed of a hub motor, and a plurality of driving teeth 221 protruding outward are arranged at equal intervals on the outer periphery of the driving wheel 22. The inner side surface 241 of the driving track 24 is surrounded by a plurality of recessed holes 242 adapted to the driving teeth 221, and the recessed holes 242 penetrate to the outer side surface 243 of the driving track. When the hub motor is running, the driving teeth 221 arranged on the outer periphery of the driving wheel 22 are driven to rotate. The driving tooth 221 is inserted into the concave hole 242 provided on the inner side 241 of the transmission track 24, and penetrates to the outer side 243 of the transmission track 24, increasing the friction between the driving tooth 221 and the concave hole 242. As the hub motor continues to operate, sufficient friction is maintained between the driving tooth 221 and the concave hole 242 to drive the transmission track 24 to rotate, thereby driving the transmission wheel 23 to rotate, and driving the crawler conveyor forward. The driving wheel 22 with the hub motor as its own power source directly drives the transmission track 24 to rotate, effectively solving the problem of power loss caused by the general engine needing to be matched with the gearbox to reduce speed, and having sufficient power to transport heavy goods, improving transportation efficiency.

The plurality of driving gears 221 can be integrally formed with the driving wheel to reduce the number of installation parts; in other applicable methods, the driving gears 221 can also be detachably installed around the outside of the driving wheel 22, and can be replaced individually according to the actual wear of each driving gear 221, thereby reducing maintenance costs; in this embodiment, as shown in FIG. 2, the driving gear 221 is composed of a gear ring 222 sleeved around the outside of the driving wheel 22, which can also achieve the same driving effect.

Since the crawler conveyor often travels on rugged terrain, the relative position between the driving crawler 24 and the driving wheel 23 is easily offset after repeated bumps, resulting in the driving tooth 221 of the driving wheel 22 being unable to be accurately inserted into the recessed hole 242, affecting the operation of the crawler conveyor. Please continue to refer to Figure 2. In order to further solve the above problem, the present invention is provided with a plurality of inwardly protruding first limit blocks 244 on the inner side surface 241 of the transmission track 24, and a plurality of the first limit blocks 244 are arranged in a ring to form a first limit circle. The inner side surface of the transmission track is also provided with a plurality of second limit blocks 245 symmetrical to the first limit blocks 244, and a plurality of the second limit blocks 245 are arranged in a ring to form a second limit circle symmetrical to the first limit circle. A limit channel 246 for the transmission wheel to rotate is formed between the first limit circle and the second limit circle, and a plurality of the recessed holes 242 are recessed in the limit channel 246 and are arranged alternately with the plurality of the first limit blocks 244. Since the first limiting ring and the second limiting ring are located on both sides of the driving wheel 23, and the first limiting block 244 and the second limiting block 245 abut against the left and right sides of the driving wheel 23, the swing range of the driving track 24 is limited. When the crawler conveyor travels on bumpy terrain, the driving track 24 is not prone to position deviation, and the driving tooth 221 is accurately inserted into the corresponding concave hole 242.

As shown in FIG. 1, the control unit 3 is disposed on the mounting frame 13, and the control unit 3 includes a control panel (not shown) and a power supply device 31. The control panel (not shown) is electrically connected to the power supply device 31 and the driving wheel 22 of the transmission unit 2, respectively. The power supply of the power supply device 31 is controlled by the control panel to adjust the rotation speed of the driving wheel, thereby adjusting the speed of the crawler conveyor. The power supply device 31 is preferably a waterproof battery box.

The crawler conveyor provided by this invention can achieve the following improvements:

First, the structure is light and easy to use. This creation uses a lightweight transmission mechanism composed of a single crawler combined with a wheel hub motor, which significantly reduces the weight of the crawler transporter itself. It is easy and convenient to use, and has a small size, making it suitable for small-scale farmland, fruit and vegetable gardens, and flower gardens.

Second, the center of gravity is stable and not prone to tipping over. This invention places the transmission mechanism under the frame and is supplemented by two auxiliary wheels to form a stable triangular support structure. The frame is pivoted to the top of the connecting frame of the transmission mechanism with a support seat, which can support the pivoting movement as an axis. When the crawler transporter travels on rugged terrain, the center of gravity of the frame can be better adjusted and it is not prone to tipping over.

Third, the power is directly transmitted to the driving wheel, reducing power loss; this creation uses the wheel hub motor as the driving wheel and also as the driving power source, reducing the power loss caused by multiple transmissions of the driving power source, so that the crawler transporter of this creation has sufficient power to transport heavy objects.

However, the above is only a preferred embodiment of this creation, and it cannot be used to limit the scope of this creation. In other words, all equivalent changes and modifications made within the scope of the patent application should still fall within the scope of this creation patent.

In summary, those who are familiar with this technology should be able to understand that this creation can indeed achieve the above-mentioned purpose and actually complies with the provisions of the Patent Law, so they can apply for it in accordance with the law.
