Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery and equipment, in particular to a double-row reinforced rotary tiller ground roller which is convenient for welding and installation. Background Technique

[0002] The rotary tiller ground roller is a component installed at the rear of the rotary tiller and is used to compact and level the soil that has undergone rotary seeding treatment. It is usually composed of a series of metal rollers, and these rollers can be connected to the power source of the rotary tiller through a transmission system to facilitate good compaction of the soil after rotary seeding. The functions of the rotary tiller ground roller include: through the weight and pressure of the rollers, the ground roller can compact the soil processed by the rotary tiller to make it more uniform and compact. The ground roller can help make the soil surface more flat, providing a better foundation for planting crops or other land uses. Appropriate compaction can improve the air permeability of the soil and contribute to the growth of planted crops.

[0003] However, the existing rotary tiller ground rollers often encounter the following problems during use:

[0004] (1) When welding the axle head of the ground roller, a long iron pipe is used to penetrate the roller to calibrate the center of the circle, and then the axle head is installed for welding. This welding method is relatively cumbersome, affecting the batch production efficiency, and the long iron pipe used for penetration has no function except for the two ends used for positioning, so it wastes materials and causes unnecessary costs.

[0005] (2) When the ground roller is rolling, if it encounters large stones or irregular undulating terrain, due to the smooth surface of the ground roller, it cannot climb over the obstacles, and its rolling behavior will be blocked, resulting in inconvenient movement. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a double-row reinforced rotary tiller ground roller which is convenient for welding and installation, so as to effectively solve the problem that the existing welding method for installing the axle head needs to use a long iron pipe, which wastes materials and causes unnecessary costs mentioned in the background technique.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A double-row reinforced rotary tiller ground roller which is convenient for welding and installation, comprising:

[0009] A roller, the roller being a hollow cylinder;

[0010] Inner lining discs, at least two of the inner lining discs being clamped into the barrel openings at both ends of the roller;

[0011] Positioning discs, the positioning discs being located in the extending direction on one side of the inner lining discs;

[0012] Ground roller shaft head, two ground roller shaft heads are provided, and one ends of the two ground roller shaft heads are respectively inserted through the lining discs and the positioning discs at both ends of the roller barrel;

[0013] Roller teeth, several roller teeth are provided, and several roller teeth are annularly distributed around the outer surface of the roller barrel.

[0014] It further includes:

[0015] Connection notch, the connection notch is opened at the connection ends of the two ground roller shaft heads;

[0016] Reinforcing plate, the reinforcing plate is sleeved on the shaft body of the ground roller shaft head.

[0017] The size of the positioning disc is the same as that of the lining disc.

[0018] At least two of the positioning discs are snap-connected to the barrel openings at both ends of the roller barrel.

[0019] Two sets of the roller teeth are provided, and the two sets of roller teeth are arranged side by side on the outer surface of the roller barrel.

[0020] The reinforcing plate is fixedly connected to one side of the positioning disc.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] (1) For the double-row reinforced rotary tiller ground roller designed by the present utility model, by adding ground positioning discs at both ends of the drum, better fixation and stability can be provided, reducing the shaking and deviation of the drum during the working process, and helping to compact and level the soil more evenly. And it simplifies the installation process. The shaft head can be directly inserted into the positioning disc without using a long iron pipe to penetrate the center of the drum to position the shaft head, which can simplify the installation process, reduce the material cost and improve the production efficiency.

[0023] (2) For the two circles of roller teeth designed by the present utility model distributed on the surface of the drum, the wear resistance and durability of the drum can be increased. And the roller teeth are sharp triangles. When encountering stones or irregular terrains, the roller teeth will increase the friction with the terrain, thereby helping the cylinder to roll. This reduces the contact of the ground roller itself with stones or irregular terrains, thereby extending the service life and reducing the maintenance cost. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] As Figure 1-2 shown, a double-row reinforced rotary tiller ground roller for facilitating welding and installation includes: a roller 1, an inner lining disc 2, a positioning disc 3, a ground roller shaft head 4, roller teeth 5, a connecting notch 6, and a reinforcing plate 7. The roller 1 is a hollow cylinder, and at least two inner lining discs 2 are clamped into the barrel openings at both ends of the roller 1. The inner lining discs 2 are clamped into the barrel openings at both ends of the roller 1. The design purpose is to provide a stable support structure, so that the roller 1 remains stable during high-speed rotation, reduces vibration and deformation, and thus improves the working accuracy and efficiency. The positioning disc 3 is located in the extending direction on one side of the inner lining disc 2. The size of the positioning disc 3 is the same as that of the inner lining disc 2. At least two positioning discs 3 are clamped to the barrel openings at both ends of the roller 1. There are two ground roller shaft heads 4. One ends of the two ground roller shaft heads 4 respectively pass through the inner lining discs 2 and the positioning discs 3 at both ends of the roller 1. There are several roller teeth 5. The several roller teeth 5 are annularly distributed around the outer surface of the roller 1. There are two groups of roller teeth 5. The two groups of roller teeth 5 are arranged side by side on the outer surface of the roller 1. The connecting notch 6 is opened at the connecting end of the two ground roller shaft heads 4. The reinforcing plate 7 is sleeved on the shaft body of the ground roller shaft head 4. The reinforcing plate 7 is fixedly connected to one side of the positioning disc 3.

[0031] Preferably, the reinforcing plate 7 is sleeved on the shaft body of the ground roller shaft head 4 and fixedly connected to one side of the positioning disc 3. The design of the reinforcing plate 7 enhances the supporting force of the shaft body, improves the structural strength of the entire ground roller, and ensures good performance even in harsh working environments.

[0032] In this embodiment, as Figure 2 shown, the positioning disc 3 and the inner lining disc 2 have the same size and are also clamped at the barrel openings at both ends of the roller 1. Their function is to enhance the overall strength of the roller 1, prevent it from displacing or twisting during operation, ensure the correct position of the ground roller shaft head 4, and thus ensure the stability and reliability of the entire ground roller. One end of the ground roller shaft head 4 passes through the inner lining disc 2 and the positioning disc 3 at both ends of the roller 1. This design simplifies the installation process, reduces material costs, and at the same time improves the stability and load-bearing capacity of the shaft head, ensuring the smooth operation of the ground roller. The roller teeth 5 are annularly distributed around the outer surface of the roller 1 and are arranged in two rows side by side. The shape of the roller teeth 5 is a sharp triangle. Such a design can increase the friction force when encountering stones or uneven terrain, help the barrel roll better, reduce the impact on the ground roller itself, and extend the service life.

[0033] It should be noted that for a double-row reinforced rotary tiller ground roller designed by the present utility model, during use, when the ground roller shaft head 4 needs to be welded, it only needs to be directly passed through the centers of the inner lining disc 2 and the positioning disc 3 at both ends of the roller 1 for welding. When the ground roller rolls, if it encounters stones or irregular undulating terrain, due to the smoothness of the ground roller, the setting of the roller teeth 5 will increase the friction force with the terrain, thereby helping the barrel roll. This reduces the contact of the ground roller itself with stones or irregular terrain. Thus, the disassembly process ends.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it is understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
