Specific implementation

[0030] It should be understood that the specific embodiments described herein are merely intended to explain the utility model, and are not used to limit the utility model.

[0031] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] It should be noted that all directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directionality indications also change accordingly.

[0033] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, also not in the protection scope required by the present application.

[0034] Please refer to the attached Figures 1-4 The utility model provides a seeding machine in one embodiment, including frame 70 and setting up transmission mechanism 10, fertilizer distribution mechanism 20, seed metering mechanism 30, rotary tillage assembly 40 and protection assembly 50 on frame 70. First, it needs to be explained that the longitudinal direction in the present application refers to the driving extension direction of the whole mechanical device, and the transverse direction refers to the ditch width direction after ridging and ditching, please refer to the marked in the attached drawing, the front end refers to the advancing direction, and the rear end refers to the rear of the mechanical device. Unlike the rear-mounted press roller used as the driving power of the seeding machine in most seeding machines on the market in the prior art, chain is used as the main transmission structure. However, when such seeding machine is used in the southern viscous soil, the rear press roller is stuck or the chain is broken due to the adhesion of viscous soil, which cannot work normally. And the transmission machine is usually located in the middle, so that a middle ditch mark is left after ridging. The present application solves the above-mentioned defects in the prior art by providing a seeding machine, as follows:

[0035] The fertilizer distribution mechanism 20 and the seed metering mechanism 30 are connected side by side on the top of the frame 70 in the longitudinal direction, and the fertilizer distribution mechanism 20 and the seed metering mechanism 30 are independently arranged between each other. The rotary tillage assembly 40 is rotatably connected to the bottom of the frame 70. The transmission mechanism 10 includes a first transmission assembly 110 and a second transmission assembly 120. The first transmission assembly 110 is rotatably connected to the frame 70. The input end of the first transmission assembly 110 is used to connect with the external tractor. The second transmission assembly 120 is installed on one side of the frame 70 in the transverse direction. One end of the first transmission assembly 110 is in transmission connection with the second transmission assembly 120. The second transmission assembly 120 and the rotary tillage assembly 40 are in transmission connection. The protection assembly 50 is connected to one side of the frame 70 and covers the bottom of the second transmission assembly 120.

[0036] Specifically, the seeding machine in the application comprises a frame 70, a transmission mechanism 10, a fertilizer distribution mechanism 20, a seed distribution mechanism 30, a rotary tillage assembly 40 and a protection assembly 50. The frame 70 is the main frame of the whole mechanical device for mounting the remaining components. The transmission mechanism 10 is used to convert the external driving force into the power for rotating the rotary tillage assembly 40 through transmission connection, so as to perform the rotary tillage and ridge forming operation through the rotary tillage assembly 40. The fertilizer distribution mechanism 20 and the seed distribution mechanism 30 are respectively used to perform the fertilizer distribution operation and the seed distribution operation after the ridge forming. The protection assembly 50 is used to protect the side and bottom positions of the transmission mechanism 10 to avoid the wear during the operation.

[0037] Among them, the fertilizer distribution mechanism 20 and the seed distribution mechanism 30 are connected side by side in the longitudinal direction on the top of the frame 70 to respectively perform the fertilizer distribution and seed distribution from the two sides (the front end and the rear end) in the longitudinal direction. It should be noted that the independent arrangement between the two means that the fertilizer distribution mechanism 20 and the seed distribution mechanism 30 respectively perform the fertilizer distribution and seed distribution through the motors controlled independently, which is different from the equipment performing the fertilizer distribution and seed distribution at the same time, has more independent operability and space, and can be controlled in real time according to the needs, thereby improving the operation flexibility and convenience. The rotary tillage assembly 40 is rotatably connected to the bottom of the frame 70. After the external driving force is converted into the power through the transmission mechanism 10, the rotary tillage assembly 40 is driven to rotate to perform the rotary tillage and ridge forming operation.

[0038] The transmission mechanism 10 includes a first transmission component 110 and a second transmission component 120. The first transmission component 110 serves as the first transmission force, transmitting the external driving force to the second transmission component 120 through a first transmission process. Therefore, the input end of the first transmission component 110 is used to connect to an external tractor, using the power output from the PTO output shaft of the external tractor as the main driving force. This is a common technique in agricultural rotary tillage, and will not be elaborated upon here. The first transmission component 110 itself needs to be rotatably mounted on the frame 70 so that after being driven to rotate, it can drive the second transmission component 120 to rotate. Therefore, it is easy to understand that the second transmission component 120 serves as the second transmission force, transmitting the power through the first transmission component 110. After the drive transmission is completed, the rotational power is transmitted to the rotary tillage component 40, thereby achieving the purpose of rotary tillage and ridging. Unlike traditional mechanical equipment, the second transmission component 120 in this application is installed on one side of the frame 70 along the lateral direction to adopt a side transmission form. In this way, the transmission structure does not need to be set in the middle of the rotary tillage component 40 for transmission, so no middle groove will appear after ridging, ensuring the ridging effect. It is worth noting that since the rotary tillage component 40 is set at the bottom of the frame 70, part of the structure of the second transmission component 120 during transmission connection is also located at the bottom side of the frame 70. In this way, friction damage with the soil is likely to occur during operation. Therefore, the protective component 50 is added to avoid wear on the bottom of the second transmission component 120.

[0039] In a preferred embodiment of the present invention, the first transmission assembly 110 includes a gearbox 111 and a drive shaft 112. The gearbox 111 is connected to the middle of the frame 70. The input end of the gearbox 111 is used to connect to an external tractor.

One end of the drive shaft 112 is connected to the frame 70, and the other end of the drive shaft 112 is connected to the second transmission assembly 120.

[0040] It should be noted that the gearbox 111 can adjust the driving speed according to the traction speed of the tractor, and has good adaptability, and therefore it is suitable for being connected with the external tractor PTO output shaft, and the transmission shaft 112 is used for converting the output power of the external tractor PTO output shaft in the gearbox 111 and then transmitting the power to the second transmission assembly 120, and therefore the transmission shaft 112 penetrates through the gearbox 111 and extends out of the gearbox 111 at both ends, and the part of the transmission shaft 112 in the gearbox 111 is connected in a conical gear transmission mode, which is a common structure in the gearbox 111, and will not be described in detail here; and the two ends of the transmission shaft 112 are rotatably connected to the rack 70 at one end, so that the entire transmission shaft 112 is rotatably arranged, and the other end is connected with the second transmission assembly 120, so as to drive the second transmission assembly 120 to rotate.

[0045] As a preferred embodiment of the utility model, the protection assembly 50 further comprises a protection bottom plate 520, and the protection bottom plate 520 is connected to the bottom end of the transmission box 121.

[0046] It is worth noting that the protection bottom plate 520 is used for protecting the bottom end of the transmission box 121 to avoid the friction and wear of the bottom end surface and the bottom surface of the ridge ditch during driving after ditching.

[0047] Further, the protection bottom plate 520 and the bottom end of the transmission box 121 are matched in an arc shape.
