[0002] A transplanter is a piece of machinery used in agriculture. Its primary function is to plant seedlings or seeds into the soil at a predetermined spacing and depth. To achieve this, the transplanter requires a series of key mechanisms, of which the "hole-opening device" is a crucial component.

[0003] The main function of a hole-digging device is to dig a small pit (a "hole") in the soil suitable for planting seedlings or seeds, and to control the size and depth of this hole to meet the planting requirements of different crops. Furthermore, it must ensure that the soil structure is not damaged during digging, and that a certain humidity level is maintained in the hole to facilitate the growth of the seedlings. Existing hole-digging devices for transplanters use a furrow-type, eccentric disc mechanism, which can easily cause the seedlings to be planted in an unbalanced position, prolonging the crop's greening cycle.

[0028] According to a first aspect of the present invention, a hole opening device is provided, such as Figures 1 to 4 As shown, the hole-opening device is used for a transplanter, which can make the crops have a good planting posture and turn green quickly. The hole-opening device includes a mounting beam 1, a transmission mechanism 2 and a hole-opening mechanism 3.

[0029] In the following description, reference will be made to Figures 1 to 4 The detailed structures of the mounting crossbeam 1 , the transmission mechanism 2 and the hole-opening mechanism 3 of the hole-opening device are described in detail.

[0030] like Figures 1 to 3As shown, in the embodiment, the transmission mechanism 2 and the hole-opening mechanism 3 are both arranged on the mounting crossbeam 1. The mounting crossbeam 1 can be, for example, the main structure of the transplanter, and is used for the layout of the transmission mechanism 2 and the hole-opening mechanism 3. Specifically, the transmission mechanism 2 includes a driving shaft 201, a driven shaft 202, a transmission assembly and a mounting assembly 5. The driving shaft 201 and the driven shaft 202 are arranged correspondingly. The driving shaft 201 can be connected to the transmission box through a coupling. The transmission box drives the driving shaft 201 to rotate, and the driving shaft 201 drives the driven shaft 202 to rotate. The driving shaft 201 is arranged on the mounting crossbeam 1 to achieve fixation and installation. The driven shaft 202 is installed on the mounting crossbeam 1 through the mounting assembly 5, and the driving shaft 201 drives the driven shaft 202 to rotate through the transmission assembly. That is, it can be understood that the mounting assembly 5 is used for the installation of the driven shaft 202, and the transmission assembly is used to drive the driven shaft 202 to rotate. The hole opening mechanism 3 includes a hole opener, which is arranged on the driven shaft 202. The hole opener is driven by the driven shaft 202 to rotate to realize the hole opening operation.

[0031] The hole-opening device includes a hub body 301 and multiple hole-opening rods 302. These rods 302 are arranged circumferentially around the hub body 301, with adjacent rods 302 forming the same angle. The rods 302 can be shaped like a cylinder. When the driven shaft 202 rotates the hole-opening device, each rod 302 creates a hole, and each hole can be used to plant a crop. The holes created by this hole-opening device can be used to plant crops, ensuring a smooth, healthy planting posture and rapid greening.

[0032] The hole-opening device can quickly perform hole-opening operations through the cooperation of the transmission mechanism 2 and the hole-opening mechanism 3, thereby ensuring the efficiency of crop planting. Since the transmission mechanism 2 adopts the transmission form of the active shaft 201 and the driven shaft 202, it can solve the problem that the seedling planting posture is easily skewed due to the use of the trenching type or eccentric disc type mechanism in the original device, resulting in an extension of the crop greening cycle. The overall structure of the hole-opening device is simple. Through the cooperation of the active shaft 201, the driven shaft 202, the transmission assembly and the mounting assembly 5, a chain-type transmission structure with high transmission efficiency can be realized, thereby ensuring planting efficiency and quality, improving the hole-opening speed, making the crop planting posture good, and shortening the greening cycle.

[0033] Preferably, if Figures 1 to 3 As shown, in the embodiment, the transmission assembly may include a driving sprocket 401, a chain 402, and a driven sprocket 403. The driving sprocket 401 is provided at the end of the driving shaft 201, and the driven sprocket 403 is provided at the end of the driven shaft 202. The driving sprocket 401 and the driven sprocket 403 are connected by the chain 402. The transmission assembly realizes a chain drive transmission form through the cooperation of the driving sprocket 401, the chain 402, and the driven sprocket 403. However, the present invention is not limited thereto. The chain 402 may also be changed to a belt, thereby changing the chain drive to a belt drive.

[0034] Preferably, if Figures 1 to 3 As shown, in an embodiment, the transmission assembly may further include a connecting key 404, a locking bolt 405, and a locking nut 406. The driving sprocket 401 is connected to the driving shaft 201 via the connecting key 404, and the driven sprocket 403 is connected to the driven shaft 202 via the connecting key 404. The driving sprocket 401 and the driven sprocket 403 are both connected via the connecting key 404. The ends of the driving shaft 201 and the driven shaft 202 are both provided with locking bolts 405 and locking nuts 406, which restrict axial movement of the driving sprocket 401 and the driven sprocket 403. To prevent axial movement of the driving sprocket 401 and the driven sprocket 403, additional locking bolts 405 are provided at the ends of the driving shaft 201 and the driven shaft 202 for limiting position. The locking bolts 405 are secured by locking nuts 406.

[0035] Preferably, if Figure 4 As shown, in the embodiment, the transmission mechanism 2 may further include a shaft tube 203 and a shaft head 204, wherein the shaft tube 203 is sleeved on the driven shaft 202, and the shaft head 204 is provided at the end of the driven shaft 202. The hole opening mechanism 3 is sleeved on the shaft tube 203, and the rotation of the driven shaft 202 drives the hole opening mechanism 3 to rotate.

[0036] Preferably, if Figures 1 to 4 As shown, in this embodiment, the mounting assembly 5 may include a mounting base assembly and a mounting base plate 501. The driven shaft 202 passes through the axial hole of the mounting base assembly, and the mounting base assembly is mounted on the mounting beam 1 via the mounting base plate 501. The mounting base plate 501 can be formed into a bracket structure to support and connect the driven shaft 202. The central portion of the mounting base assembly has an axial hole for passing the driven shaft 202. The driven shaft 202 can be fixed by the mounting assembly 5.

[0037] Preferably, if Figures 1 to 4 As shown, in an embodiment, the mounting seat assembly may include an upper mounting seat 502, a lower mounting seat 503, a mounting seat pin 504, and a spacer 505. The lower mounting seat 503 is connected to the upper mounting seat 502 via the spacer 505. The mounting seat pin 504 is disposed between two adjacent spacers 505 to limit the position. The mounting seat pin 504 is used to limit the position of the spacer 505. The spacer 505 is used to assemble the upper mounting seat 502 and the lower mounting seat 503 so that the driven shaft 202 can rotate within the mounting seat shaft hole. The lower mounting seat 503 is connected to the upper mounting seat 502 via connecting bolts, and the upper mounting seat 502 is connected to the mounting beam 1 via connecting bolts.

[0038] Preferably, if Figures 1 to 3As shown, in the embodiment, there are multiple hole openers, which are sequentially and spaced apart and arranged on the mounting beam 1. Since multiple hole openers are provided, each time the driven shaft 202 rotates, multiple hole positions can be opened in the axial direction of the driven shaft 202, thereby improving the efficiency of the hole opening operation.

[0039] Preferably, if Figures 1 to 3 As shown, in the embodiment, every two adjacent hole-opening mechanisms 3 correspond to a planting mechanism 6, and a planting mechanism 6 and the corresponding hole-opening mechanism 3 are respectively arranged at both ends of the mounting beam 1. The planting mechanism 6 can be an existing device in a transplanter that can realize crop planting. The structure and principle of the planting mechanism 6 are known to those skilled in the art and will not be repeated here. One planting mechanism 6 can be used to plant crops for two adjacent hole-opening mechanisms 3.

[0040] Preferably, if Figure 3 As shown, in this embodiment, there are five hole-opening rods 302, and the angle between two adjacent hole-opening rods 302 is 72°. Every 72° rotation of the driven shaft 202 drives one hole-opening rod 302 to open one hole. Because the multiple hole-opening rods 302 are arranged at equal intervals, the hole-opening spacing and angle are consistent during each hole-opening operation, thereby ensuring the quality of the opened holes, ensuring good crop interpolation posture, and shortening the regreening cycle.

[0041] The working principle of the hole-opening device is as follows: when the transmission box drives the driving shaft 201 to rotate, the driving sprocket 401 drives the driven sprocket 403 to rotate via the chain 402. The driven sprocket 403 drives the driven shaft 202 to rotate. The rotation of the driven shaft 202 drives the hole-opening mechanism 3 to rotate. Every two adjacent hole-opening devices correspond to a planting mechanism 6. Each time the driven shaft 202 rotates 72 degrees, the hole-opening rod 302 of the hole-opening device opens a new hole.

[0042] The hole-opening device, through the cooperation of the transmission mechanism and the hole-opening mechanism, can quickly perform hole-opening operations and ensure the efficiency of crop planting. Because the transmission mechanism adopts the transmission form of the driving shaft and the driven shaft, it can solve the problem of the original device using the furrow-opening or eccentric disc mechanism, which causes the seedling planting posture to be easily skewed, resulting in a prolonged crop regreening cycle. The overall structure of the hole-opening device is simple. Through the cooperation of the driving shaft, the driven shaft, the transmission assembly and the installation assembly, it can realize a chain-type transmission structure with high transmission efficiency, ensure planting efficiency and quality, improve the hole-opening speed, make the crop planting posture good, and shorten the regreening cycle.

[0043] Furthermore, according to a second aspect of the present invention, a transplanter is provided, comprising the aforementioned hole-forming device. This transplanter, by utilizing a chain-driven hole-forming device, can address the problem of conventional devices employing furrow-forming or eccentric disc mechanisms, which can cause the seedlings to be easily misaligned during planting and thus prolong the crop's greening period.

[0044] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
