Description

Technical Field

[0001] The utility model relates to the technical field of agricultural mechanization, and particularly relates to a battery installation structure for a rice transplanter. Background Art

[0002] In recent years, due to the popularization of new energy technologies in the automotive industry, the agricultural machinery industry has also accelerated the new energy transformation of agricultural machinery. Because new energy technologies have many advantages such as improving energy utilization efficiency, reducing energy costs, and operating with low noise, the new energy transformation of the agricultural machinery industry has been accelerated. Due to the electrification of rice transplanters, a power battery pack needs to be set in the rice transplanter, and the placement position and fixing method of the battery pack determine the space utilization rate and battery usage safety of the rice transplanter.

[0003] Grant Publication Number: CN 221010755 U, Application Date: September 27, 2023, Utility Model Name: An Agricultural Rice Transplanter. This utility model provides an agricultural rice transplanter, including a bottom plate. A driving mechanism is installed on the top surface of the bottom plate, and a rice transplanting mechanism is installed at the front end of the bottom plate. Two groups of fixing plates are symmetrically installed on the top surface of the bottom plate in an inclined manner, and a reciprocating mechanism for the seedling tray is installed at the top ends of the two groups of fixing plates. The driving mechanism is in transmission connection with the rice transplanting mechanism and the reciprocating mechanism for the seedling tray. A battery box is installed on the top surface of the bottom plate, and the top end of the battery box is open. A U-shaped plate is slidably installed inside the battery box, and L-shaped clamping blocks are symmetrically installed at the bottom end of the U-shaped plate. A chute is opened on the bottom surface inside the battery box, and a clamping plate is slidably installed inside the chute. By the coordinated use of the motor, wheels, driving mechanism, and rice transplanting mechanism, the wheels can automatically run through the motor, and at the same time, the driving mechanism can drive the rice transplanting mechanism to enable the device to quickly transplant rice seedlings, saving manpower and improving the operation efficiency.

[0004] In the above-mentioned prior art, the battery box is directly placed on the frame of the rice transplanter. Since the rice transplanter walks and works in paddy fields, in order to facilitate the replacement of the storage battery, the bottom of the battery box is not sealed. Therefore, there is a risk that the storage battery will be flooded with water and mud.

[0005] When replacing the storage battery, since the battery box is sealed circumferentially and the top end is open, the storage battery can only be vertically taken out from above, and the handle installed at the top end of the U-shaped plate must be used in cooperation during the process of taking out the storage battery. Therefore, it is rather laborious to replace the storage battery. The battery box does not have a height limiting device for the storage battery. If the rice transplanter jolts during walking, the storage battery will have a vertical displacement, that is, the storage battery will jump, resulting in a risk of electric leakage.

[0006] In addition, the above-mentioned prior art does not disclose the specific structure of the frame of the rice transplanter. Content of the Utility Model

[0054] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0055] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in this specification for understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the utility model and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in this utility model without affecting the efficacy and purpose of the utility model. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the utility model without substantially changing the technical content.

[0056] The working principle and structural characteristics of the rice transplanter determine the core role of the frame. As the supporting structure of the entire machine, the frame's design and quality directly affect the stability and efficiency of the transplanting operation.

[0057] The frame, through its structure and design, provides a stable working platform for the rice transplanter. During operation, the stable frame ensures accurate and consistent transplanting, preventing uneven planting depth or position deviations caused by machine movement.

[0058] The frame design should take into account different soil conditions and working environments. A well-designed frame can adapt to different field conditions, such as soil hardness and moisture, to ensure that the machine can operate stably under different conditions.

[0059] The frame's structure and material selection directly impact the transplanter's overall weight and center of gravity, which in turn influences the machine's movement speed and operating efficiency. During the transplanting process, the frame's design also effectively protects the seedlings, preventing damage caused by the machine's own weight or structural issues.

[0060] As the main supporting structure of the rice transplanter, the frame also needs to connect and fix other key components, such as the planting part, power system, etc., to ensure that these components can work normally.

[0061] Example 1

[0062] The present application solution installs the battery on the rice transplanter frame, specifically, at the front end of the topmost frame to prevent the battery from entering water or mud.

[0063] The present application discloses a rice transplanter battery installation structure, comprising a basic support beam and an upper frame 4, wherein the basic support beam further comprises a bottom frame 2 and a middle frame 3, and the basic support beam and the upper frame 4 constitute the general frame structure of the vehicle frame, and the basic support beam adopts a two-layer steel structure, which balances the overall weight and center of gravity distribution of the rice transplanter.

[0064] like Figure 1 、 Figure 2 As shown, the middle frame 3 is located directly above and parallel to the bottom frame 2. The two are fixedly connected by first connectors 5. The first connectors 5 are at least 20 cm high and include corner connectors located at the four corners of the bottom frame 2. The corner connectors are special-shaped structures. Their main purpose is to increase the contact area between the bottom frame 2 and the middle frame 3, ensuring the stability of the connection between the two layers of the foundation support beam.

[0065] like Figure 8 As shown, the corner connector includes a side fixing end 51 and an intermediate fixing end 52 integrally formed with the side fixing end 51. The side fixing end 51 is vertically arranged on the inner side of the foundation support beam. The cross-section of the side fixing end 51 is right-angled. The purpose of setting it at a right angle is to increase its own strength. One of the right-angled sides of the side fixing end 51 is welded to the inner side of the bottom frame 2 and the middle frame 3. The intermediate fixing end 52 is located between the bottom frame 2 and the middle frame 3 and is inclined relative to the bottom frame 2 and the middle frame 3. The purpose of the inclined setting is to increase stability.

[0066] The first connector 5 also includes a middle connector. Along the travel direction of the rice transplanter, the middle connector is located between a group of corner connectors. The middle connector is also used to fixedly connect the bottom frame 2 and the middle frame 3. Therefore, through the fixed connection of the corner connectors and the middle connector to the bottom frame 2 and the middle frame 3, preferably by welding, the basic support beam forms a steel structure with sufficient strength.

[0067] More specifically, the bottom frame 2 and the middle frame 3 have the same width. Along the travel direction of the rice transplanter, both ends of the middle frame 3 extend out of the bottom frame 2. The horizontal distance between the end of the bottom frame 2 and the end of the middle frame 3 on the same side provides installation space for accommodating wheels.

[0068] Reinforcing ribs are provided in the middle of the bottom frame 2, the middle of the middle frame 3, and between the bottom frame 2 and the middle frame 3. The reinforcing ribs can play an important role in ensuring the local stability of the foundation support beam, enhancing the torsional resistance of the structure, and avoiding deformation or damage of the structure due to excessive load. They provide important support and guarantee for the overall structural strength of the foundation support beam, and further balance the overall weight and center of gravity distribution of the rice transplanter.

[0069] like Figure 4 、 Figure 5 As shown, a bracket 31 is fixedly connected to the bottom of the middle frame 3, with both sides of the bracket 31 extending beyond the middle frame 3. Along the travel direction of the rice transplanter, the width of the bracket 31 matches the width of the batteries. Along the axle direction, the portion of the bracket 31 extending beyond the middle frame 3 matches the length of the batteries. Bracket 31 also features stoppers at both ends to limit the battery's position. Therefore, the portion of the bracket 31 extending beyond the middle frame 3 can accommodate two sets of spare batteries.

[0070] The purpose of fixing the bracket 31 to the bottom of the middle frame 3 rather than to the bottom frame 2 is to prevent the battery from being splashed by muddy water in the paddy field and prevent the battery from becoming damp and failing.

[0071] Bracket 31 effectively utilizes the space on either side of the foundation support beam, and the symmetrical placement of the backup battery compartment prevents the foundation support beam's center of gravity from shifting. The overall frame was designed so that the height difference between the middle frame 3 and the upper frame 4 is greater than the height of the batteries. Furthermore, the overall frame was designed so that there is no obstruction above the backup battery compartment. Specifically, the upper frame 4 avoids the corresponding skeletal design at the corresponding location of the backup battery compartment, facilitating battery replacement within the compartment.

[0072] The upper frame 4 is fixedly connected to the middle frame 3 by a second connecting member 6, and the height of the second connecting member 6 is not less than 30 cm. Along the axle direction of the rice transplanter, the width of the upper frame 4 is greater than the width of the middle frame 3, and the upper frame 4 can provide a basic space structure for people to walk.

[0073] More specifically, if Figure 6 、 Figure 7 As shown, the upper frame 4 includes a first crossbar 41, a second crossbar 42, and a third crossbar 43, which are parallel to each other and increase in length. The center line of the three crossbars is perpendicular to the direction of the rice transplanter axle. The upper frame 4 also includes reinforcing rods 7, which are symmetrically arranged along the direction of the rice transplanter axle, and there are no fewer than two reinforcing rods 7.

[0074] The reinforcing rod 7 includes an upper reinforcing rod 71, a lower reinforcing rod 72 parallel to the upper reinforcing rod 71 and located below it, and a connecting rod 73 connecting the upper reinforcing rod 71 and the lower reinforcing rod 72. The connecting rod 73 is roughly perpendicular to the upper reinforcing rod 71 and the lower reinforcing rod 72. The reinforcing rod 7 is preferably an integrally formed steel pipe, which is bent to form the above-mentioned upper reinforcing rod 71, lower reinforcing rod 72 and connecting rod 73.

[0075] The lower reinforcing rod 72 passes through the first crossbar 41 , the second crossbar 42 and the third crossbar 43 in sequence. The upper frame 4 forms a more stable steel structure as a whole through the lower reinforcing rod 72 and the three crossbars that are perpendicular to each other.

[0076] A fourth crossbar 44 is provided on the rear side of the third crossbar 43 and is parallel thereto. The fourth crossbar 44 is fixedly connected to the lower reinforcing bar 72. Along the outward extension direction of the rice transplanter axial direction, at least two horizontal bars parallel to the lower reinforcing bar 72 are provided on each side. The horizontal bars are located on the outside of the lower reinforcing bar 72 and are perpendicular to the first crossbar 41, the second crossbar 42, and the third crossbar 43.

[0077] The horizontal bars include a first horizontal bar 45 and a second horizontal bar 46 located outside the first horizontal bar 45. The second horizontal bar 46 is shorter than the first horizontal bar 45. The first horizontal bar 45 is fixedly connected to the second crossbar 42, the third crossbar 43, and the fourth crossbar 44 at their contact points. The second horizontal bar 46 is also fixedly connected to the third crossbar 43 and the fourth crossbar 44 at their contact points. This densely gridded frame structure further enhances the overall structural strength of the upper frame 4.

[0078] The part of the upper frame 4 that is wider than the foundation support beam is the pedal part of the personnel walking space, and the staff gets on and off the rice transplanter by the pedal.

[0079] The overall frame of the rice transplanter also includes a seat support portion 8, which is fixed to the middle frame 3 and located between the reinforcing rods 7. The two sides of the seat support portion 8 are fixedly connected to the connecting rods 73 via reinforced portions 81, thereby ensuring the overall stability of the seat support portion 8. The seat support portion 8 is located on the rear side of the upper frame 4 and is higher than the upper frame 4. After the seat is installed on the seat support portion 8, it can ensure that the driver's legs have more room to move, and the seat height is appropriate. The thighs can be roughly parallel to the upper frame 4, and the feet can be placed flat on the upper frame 4, improving the comfort of the driver's legs.

[0080] The space between the seat support portion 8 and the front upper frame 4 needs to be able to simultaneously meet the necessary leg movement space for the driver after sitting down and the space required for installing the steering wheel.

[0081] The rice transplanter frame also includes a load-bearing section 9, located behind the seat support 8. This section includes a load-bearing member 91 fixedly connected to the middle frame 3 and the seat support 8, and a crossbeam 92 parallel to the rice transplanter's axle. The height of the load-bearing member 91 does not exceed that of the upper reinforcing rod 71, and the crossbeam 92 is fixedly connected to the upper reinforcing rod 71 and the top of the load-bearing member 91, respectively.

[0082] The upper reinforcing rod 71, the load-bearing member 91 and the crossbeam 92 provide basic support for installing the load-bearing plate, which is used to bear the load of the rice transplanters standing and walking.

[0083] Example 2

[0084] This embodiment is a further solution based on the embodiment 1. The battery compartment 1 is fixedly mounted on the front end of the upper frame 4 in order to elevate the battery compartment 1 and prevent the battery from entering water or mud.

[0085] like Figure 8 As shown, the battery compartment 1 includes a base 11 and a side frame 12, which are detachably connected to each other. One end of the base 11 is open, and the base 11 is adapted to the size of the battery for accommodating the battery. The side frame 12 is provided on one side of the opening of the base 11 to limit the side of the battery.

[0086] More specifically, if Figure 9 、 Figure 10 As shown, the base 11 includes a horizontal support portion 111 and a vertical limiting portion. The vertical limiting portion and the horizontal support portion 111 are perpendicular to each other, and both are U-shaped. The horizontal support portion 111 is used to support the bottom of the battery, and the vertical limiting portion limits the side of the battery.

[0087] The vertical stopper includes two parallel first stoppers 113 and a second stopper 114 connecting the two first stoppers 113. The second stopper 114 is also perpendicular to the first stoppers 113. The connecting portion 112 is located at the end of the first stoppers 113. The connecting portion 112, the first stoppers 113, and the horizontal support portion 111 are all perpendicular to each other. In other words, the connecting portion 112 is formed by folding the end of the first stopper 113 outward.

[0088] The outer surface of the connecting portion 112 is fitted with the inner surface of the side frame 12 , and the two are detachably connected. In other words, the base 11 is detachably connected to the side frame 12 via the connecting portion 112 .

[0089] It should be noted that the base 11 is integrally formed, using an integral laser-bent plate and laser-cut blanking, which has high dimensional accuracy and low cost. In addition, when replacing the battery, only the side frame 12 needs to be removed and the battery can be pushed out immediately, saving time and effort.

[0090] The battery compartment 1 further includes two height limiting rods 13 , wherein the bottom of one height limiting rod 13 is fixedly connected to the outer side of the side frame 12 , and the bottom of the other height limiting rod 13 is fixedly connected to the outer side of the second limiting portion 114 .

[0091] The preferred method of fixed connection is welding. In order to increase the welding area, the bottom of the height limiting rod 13 is bent.

[0092] The battery compartment 1 further includes an upper pressing plate 14 , both ends of which are provided with through holes corresponding to the height limiting rods 13 . The height limiting rods 13 cooperate with the upper pressing plate 14 to limit the top of the battery.

[0093] Specifically, the upper portion of the height limiting rod 13 is provided with a thread, and the nut is adapted to the thread of the height limiting rod 13. After the battery is placed in the battery compartment 1, the upper pressing plate 14 is inserted into the height limiting rod 13, and after pressing the top of the battery, the upper pressing plate 14 is tightened with the nut to achieve the compression of the top of the battery and prevent the battery from jumping during the operation of the rice transplanter.

[0094] The utility model forms a rice transplanter frame with stable structural strength by setting a three-layer frame structure, balancing the overall weight and center of gravity distribution of the rice transplanter. The upper frame 4 not only provides space for people to walk, but also serves as a stable carrier for the battery compartment to prevent water and mud from entering the battery.

[0095] In addition, the battery compartment 1 has a simple structure, low cost, simple process, short production cycle, and low installation difficulty. When the side frame is removed, the battery can be slid out from the side, making it convenient for users to remove the battery and reducing the difficulty of after-sales maintenance.

[0096] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
