[0037] Example 1

[0038] Reference Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig.10 as well as Fig.11, which is the first embodiment of the present invention, and this embodiment provides an agricultural planting trenching machine. The agricultural planting trenching machine includes a main body component 100, including a casing 101, a mounting shaft 102, a cutter disc 103, a blade 104 and a baffle 105. The mounting shaft 102 is arranged in the casing 101, the cutter disc 103 is located outside the mounting shaft 102, the blade 104 is arranged on the cutter disc 103, and the baffle 105 is fixed to the outside of the mounting shaft 102.

[0039] The mounting shaft 102 is used to drive the cutter disc 103 and the blade 104 to rotate, so that the blade 104 can dig trenches on the ground. This is a prior art and will not be elaborated in this solution. The cutter disc 103 is blocked by the baffle 105 to prevent the cutter disc 103 from moving too far when it is mounted on the outside of the mounting shaft 102, resulting in the inability to fix it.

[0040] The connecting component 200 is arranged on the blade disc 103, and includes a locking member 201, a fastener 202, a pushing member 203, a limiting member 204 and an unlocking member 205. The locking member 201 is arranged on the blade disc 103, the fastener 202 is located on one side of the blade disc 103, the pushing member 203 is located on one side of the fastener 202, the limiting member 204 is arranged on the locking member 201, and the unlocking member 205 is located in the limiting member 204.

[0041] The locking member 201 is used to lock the cutter disc 103 and the mounting shaft 102, so that the mounting shaft 102 can drive the cutter disc 103 to rotate when rotating, and prevent the cutter disc 103 from being separated from the mounting shaft 102 when rotating. The fastener 202 is used to connect and fix the shovel blade 104 to the cutter disc 103, so that the cutter disc 103 can drive the shovel blade 104 to rotate when rotating, so that the shovel blade 104 can dig trenches on the ground. The pushing member 203 is set, and when the locking member 201 locks the cutter disc 103, it will simultaneously The pushing member 203 drives the fastener 202 to move, and enables the fastener 202 to lock the scraper 104, thereby preventing the scraper 104 from separating from the blade 103 when the blade 103 rotates. The setting of the limiting member 204 is used to limit the locking member 201, so that it cannot rotate after the blade 103 is locked, thereby preventing the blade 103 from loosening during the rotation process. The setting of the unlocking member 205 is used to drive the limiting member 204 to move, so that the limiting member 204 can release the limit on the locking member 201, so that the scraper 104 and the blade 103 can be disassembled.

[0042] Example 2

[0043] Reference Figures 1 to 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, the locking member 201 includes a connecting sleeve 201a, a movable disk 201b, a limiting column 201c, a guide column 201d, a connecting shaft 201e, a rotating plate 201f, a connecting block 201g and a handle 201h. The connecting sleeve 201a is fixed to one side of the cutter disc 103, the movable disk 201b is rotatably connected in the connecting sleeve 201a, the limiting column 201c is located in the connecting sleeve 201a, and a limiting hole Z is provided on the mounting shaft 102. The limiting column 201 c is engaged with the limiting hole Z, the guide column 201d is fixed to one side of the limiting column 201c, one end of the connecting shaft 201e is fixed to the movable disk 201b, the rotating plate 201f is fixed to the other end of the connecting shaft 201e, the connecting block 201g is fixed in the rotating plate 201f, the handle 201h is fixed to one side of the connecting block 201g, and a guide groove S-1 corresponding to the guide column 201d is opened on the movable disk 201b, and a positioning groove S-2 is opened in the guide groove S-1.

[0045] The movable disk 201b is rotatably connected with the connecting sleeve 201a through a bearing. There are multiple limiting posts 201c and limiting holes Z, which are evenly distributed in a ring shape on the outside of the installation shaft 102. When the limiting posts 201c and the limiting holes Z are engaged, the connecting sleeve 201a can be locked through the cooperation of the two, and the cutter disc 103 can be locked through the connecting sleeve 201a, so that the cutter disc 103 can be connected and fixed to the installation shaft 102. The guide posts 201d, the guide grooves S-1 and the number of the guide grooves S-1 correspond to the limiting posts 201c. There are multiple data of the connecting shaft 201e, which are used to connect the rotating plate 201f with the movable disk 201b, so that the rotating plate 201f can drive the movable disk 201b to rotate, and the connecting block 201g and the handle 201 h is convenient for the user to rotate the rotating plate 201f. When the inner wall of the guide groove S-1 has a certain curvature, the positioning groove S-2 is connected to the guide groove S-1, and the curvature of the positioning groove S-2 is the same as that of the movable disk 201b. When the limiting column 201c has not yet engaged with the limiting hole Z, its end will be inserted into the connecting sleeve 201a, and the guide column 201d will contact the end of the inner wall of the guide groove S-1. When the movable disk 201b rotates, the guide column 201d will slide along the inner wall of the guide groove S-1, and through the cooperation of the two, the limiting column 201c will be driven to engage with the limiting hole Z. At the same time, the guide column 201d will enter the positioning groove S-2. At this time, the movable disk 201b can continue to rotate, and the limiting column 201c can be locked in the current position to prevent it from separating from the limiting hole Z.

[0046] Specifically, the fastener 202 includes a fixing box 202a, a pressure plate 202b and a positioning column 202c. The fixing box 202a is fixed to one side of the blade 103, the pressure plate 202b is located in the fixing box 202a, the positioning column 202c is fixed to one side of the pressure plate 202b, and a positioning hole X is opened on the scraper 104, and the positioning column 202c is engaged with the positioning hole X.

[0047] The number of the fixing boxes 202a corresponds to the scraper 104, the pressing plate 202b is movably connected to the fixing box 202a, and one side is in contact with the scraper 104, the number of the positioning posts 202c is four, and they are fixed at the four corners of the pressing plate 202b, and one end of the positioning post 202c is in an arc shape. When the scraper 104 is inserted into the fixing box 202a, the end of the positioning post 202c is squeezed, and the pressing plate 202b is driven to move to one side through the positioning post 202c, so that the scraper 104 can be inserted In the fixing box 202a, when the scraper 104 is fully inserted into the fixing box 202a, the arc surface at the end of the positioning column 202c will enter the positioning hole X and will not penetrate into the positioning hole X. At this time, the scraper 104 can be initially fixed by the cooperation of the two, so that when the blade disc 103 is taken, the scraper 104 will not be separated from the blade disc 103. When the scraper 104 is pulled, the scraper 104 can be separated from the blade disc 103, so that the scraper 104 can be easily replaced separately.

[0048] Specifically, the fastener 202 further includes a first spring 202d and a slider 202e. Two ends of the first spring 202d are respectively fixed to the pressing plate 202b and the inner wall of the fixing box 202a. One side of the slider 202e is fixed to the pressing plate 202b.

[0049] By applying a pulling force or pushing force to the pressure plate 202b through the first spring 202d, the pressure plate 202b can stay in the current position when not under pressure, that is, the arc surface at the end of the positioning column 202c will enter the positioning hole X. If the positioning column 202c is pushed deep into the positioning hole X, when the pushing force of the positioning column 202c is lost, the pressure plate 202b and the positioning column 202c can be pulled to reset by the first spring 202d. A sliding groove is provided in the fixed box 202a, and the slider 202e slides in the sliding groove. The two are used to position the pressure plate 202b to prevent the pressure plate 202b from deviating when moving.

[0050] Specifically, the pushing member 203 includes a push rod 203a, a force block 203b, a positioning block 203c, an extrusion rod 203d and a protective cover 203e. The push rod 203a is inserted into the fixed box 202a, the force block 203b is fixed to one side of the pressure plate 202b, the positioning block 203c is fixed to one side of the knife disc 103, the extrusion rod 203d is fixed to the outside of the movable disc 201b, and the protective cover 203e is fixed to one side of the fixed box 202a.

[0051] The number of pushing members 203 corresponds to the fastener 202. The push rod 203a is movably connected with the fixed box 202a. One side of the force block 203b is inclined. The push rod 203a is movably connected with the positioning block 203c. The positioning block 203c is used to position the push rod 203a to avoid displacement during movement. One side of the extrusion rod 203d is inclined. A slot is provided on the connecting sleeve 201a. The extrusion rod 203d is movably connected with the slot. When the movable disk 201b rotates, the extrusion rod 203d is driven to move at the same time. When the inclined surface of the extrusion rod 203d contacts the push rod 203a, the push rod 203a is pushed to move, and the inclined surface of the force block 203b is squeezed by the push rod 203a, and the force block 203b is pushed to move, so that the pressure plate 202b and the positioning column 202c can be driven to move through the force block 203b. When the movable disk 201b drives the guide column 201d to slide in the guide groove S-1, the squeezing rod 203d does not contact the push rod 203a. Therefore, when the movable disk 201b is locked, the scraper 104 can still be removed by external force. Therefore, when the scraper 104 needs to be replaced separately, there is no need to disassemble the scraper disk 103 together. When the guide column 201d slides in the positioning groove S-2, the squeezing rod 203d will contact the push rod 203a and squeeze the push rod 203a. The protective cover 203e is used to isolate and protect the push rod 203a to prevent soil from accumulating on the push rod 203a during work, thereby affecting its normal movement.

[0052] Specifically, the pushing member 203 further includes a supporting block 203f and a second spring 203g. The supporting block 203f is fixed to one side of the push rod 203a, and two ends of the second spring 203g are respectively fixed to the supporting block 203f and the positioning block 203c.

[0053] The support block 203f is used to fix the second spring 203g. When the extrusion rod 203d is separated from the push rod 203a, the second spring 203g applies a thrust to the support block 203f, and the push rod 203a is driven to reset by the support block 203f.

[0054] Example 3

[0055] Reference Figures 1 to 12 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0056] Specifically, the limit member 204 includes a limit block 204a, a positioning plate 204b and a stop block 204c. A chamber V is opened in the connecting block 201g. The limit block 204a is located in the chamber V. A limit groove N is opened in the connecting sleeve 201a. The limit block 204a is engaged with the limit groove N. The positioning plate 204b is fixed to one side of the limit block 204a. The stop block 204c is fixed in the connecting sleeve 201a.

[0057] One side of the limit block 204a is inclined. When the side of the limit block 204a directly faces the inner wall of the limit slot N, the two can cooperate to limit the rotating plate 201f and the movable disk 201b, so as to avoid the limit column 201c being separated from the limit hole Z due to the rotation of the movable disk 201b after the limit column 201c is engaged with the limit hole Z. When the movable disk 201b drives the guide column 201d to enter the positioning slot S-2 along the guide slot S-1, the movable disk 201b can be prevented from rotating. When the movable disk 201b rotates in the direction of the upper part, the inclined surface of the limit block 204a will contact the inner wall of the limit groove N, and squeeze the limit block 204a through the inner wall of the limit groove N, so that the limit block 204a enters the chamber V, so that the movable disk 201b can continue to rotate. There are three limit grooves N. When the guide post 201d is located at the initial position and does not contact the positioning groove S-2, the limit block 204a is engaged with the first limit hole Z. When the movable disk 201b rotates a certain angle and the guide post 201d When the movable disk 201b is located at the connection between the guide groove S-1 and the positioning groove S-2, the limit block 204a is engaged with the second limit hole Z, and the blade disc 103 is fixed at the same time. When the movable disk 201b continues to rotate and the guide column 201d contacts the inner wall end of the positioning groove S-2, the limit block 204a is engaged with the third limit hole Z, thereby fixing the scraper 104. When only the scraper 104 needs to be disassembled, it is only necessary to engage the limit block 204a with the second limit hole Z. The scraper 104 can be disassembled without causing the blade 103 to loosen. The positioning plate 204b is used to position the limit block 204a to prevent it from shifting during movement. When the limit block 204a is engaged with the third limit hole Z, it is blocked by the stop block 204c so that it cannot move further. The corresponding numbers of the three limit holes Z are respectively subdivided into the first limit hole Z-1, the second limit hole Z-2 and the third limit hole Z-3, and are shown in detail in the figure.

[0058] Specifically, the limiting member 204 further includes a third spring 204d, and two ends of the third spring 204d are fixed to the positioning plate 204b and the inner wall of the chamber V respectively.

[0059] The third spring 204d is used to apply a thrust to the positioning plate 204b, and drive the limiting block 204a to move through the positioning plate 204b, so that the limiting block 204a and the limiting hole Z can be more tightly engaged.

[0060] Specifically, the unlocking member 205 includes a push block 205a, a force plate 205b, a connecting rod 205c and a pull rod 205d. A through slot M is opened in the limit block 204a, the push block 205a is located in the through slot M, the force plate 205b is fixed in the through slot M, one end of the connecting rod 205c is fixed to the push block 205a, and the pull rod 205d is fixed to the other end of the connecting rod 205c.

[0061] One side of the push block 205a is inclined. When the inclined surface of the push block 205a squeezes the force-bearing plate 205b, the cooperation between the two can drive the limit block 204a to move, so that the limit block 204a can be separated from the limit hole Z, thereby releasing the restriction on the rotating plate 201f, and then the rotating plate 201f can drive the movable disk 201b to rotate in the opposite direction. One end of the connecting rod 205c passes through the outside of the connecting block 201g and is movably connected to the connecting block 201g. Through the setting of the connecting rod 205c and the pull rod 205d, the user can drive the push block 205a to squeeze the force-bearing plate 205b.

[0062] Specifically, the unlocking member 205 further includes a support plate 205e and a fourth spring 205f. The support plate 205e is fixed to one side of the connecting rod 205c. Two ends of the fourth spring 205f are fixed to the support plate 205e and the inner wall of the chamber V respectively.

[0063] The support plate 205e is used to fix the fourth spring 205f. The fourth spring 205f applies a thrust to the support plate 205e, and the support plate 205e drives the connecting rod 205c and the push block 205a to move, so that the push block 205a can be reset.

[0064] During use, when the blade disc 103 and the scraper blade 104 need to be installed, firstly, the plurality of scraper blades 104 are inserted into the plurality of fixing boxes 202a in sequence.
