Description

Technical Field

[0001] The utility model relates to the technical field of chrysanthemum planting, and particularly relates to a soil loosening device for chrysanthemum planting. Background Technique

[0002] Before chrysanthemums are planted, a soil loosening device is needed to plow and loosen the soil.

[0003] After retrieval, a patent document with the publication number of "CN220935518U" discloses a soil plowing and loosening device for chrysanthemum planting. A plowing component is installed at the lower part of the main plowing frame, and a soil loosening component is installed at the rear part of the main plowing frame. The plowing component includes auxiliary plowing frames symmetrically and rotatably connected to both sides outside the main plowing frame. The bottom of the main plowing frame is equidistantly provided with first plowing knives, and the bottoms of the two auxiliary plowing frames are both equidistantly provided with second plowing knives. A traction frame is fixedly installed at the middle of the front part of the main plowing frame, and the main plowing frame and the auxiliary plowing frame are connected by an adjusting mechanism. The soil loosening component includes an adjusting frame rotatably connected to the rear part of the main plowing frame.

[0004] In the prior art, the positions of the plowing knives are relatively fixed, that is, the plowing knives move straight forward with the movement of the vehicle, and the cutting effect on the soil is also a straight cut. For the cut soil blocks, they are completely broken and turned by the soil loosening roller at the rear. However, since the soil loosening roller also moves synchronously with the vehicle and does not stay at the same place for a long time, there may be a phenomenon that the soil blocks are not completely broken by relying solely on the soil loosening roller, reducing the soil loosening effect. Therefore, a soil loosening device for chrysanthemum planting is needed. Content of the Utility Model

[0005] The purpose of this application is to provide a soil loosening device for chrysanthemum planting to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, this application provides the following technical solution: A soil loosening device for chrysanthemum planting includes a mounting frame installed on a vehicle. A soil loosening roller is rotatably installed between the side frames of the mounting frame, and a driving motor for driving the soil loosening roller to rotate is fixed at one end of the mounting frame.

[0007] A plowing knife group is arranged on the advancing direction side of the soil loosening roller. The plowing knife group is slidably connected to the mounting frame through a movable connecting piece, and the sliding direction of the plowing knife group is the same as the axial direction of the soil loosening roller.

[0008] A pushing protrusion is fixed on one side of the soil loosening roller. The pushing protrusion repeatedly abuts against or separates from the movable connecting piece as the soil loosening roller rotates. When the pushing protrusion abuts against the movable connecting piece, it drives the plowing knife group to slide towards the side close to the driving motor.

[0009] Therefore, a reset member is installed inside the mounting frame. When the pushing protrusion is separated from the movable connecting member, the reset member drives the plow knife group to slide away from the driving motor.

[0010] Preferably, the movable connecting member includes connecting side plates. There are two connecting side plates, which are respectively fixed to both ends of the plow knife group through mounting rods, and the middle part of the connecting side plates is movably sleeved on the shaft of the soil loosening roller.

[0011] During the rotation process, the pushing protrusion abuts against or separates from the side of the connecting side plate close to the soil loosening roller, and the reset member is installed on the side of the connecting side plate far from the soil loosening roller.

[0012] Preferably, the reset member includes a movable rod and a reset spring. The movable rod is fixed to the side of the connecting side plate far from the soil loosening roller. One end of the movable rod far from the connecting side plate slides through the mounting frame, and the reset spring is sleeved on the movable rod. The connecting side plate is elastically connected to the mounting frame through the movable rod and the reset spring.

[0013] Preferably, one end of the reset spring near the driving motor is fixed to the side of the connecting side plate near the driving motor, and the other end of the reset spring is fixed to the inner side of the mounting frame near the soil loosening roller.

[0014] Preferably, a limiting block is formed at one end of the movable rod far from the connecting side plate. The diameter of the limiting block is larger than that of the movable rod, and the limiting block is located on the side of the mounting frame far from the connecting side plate.

[0015] Preferably, one end of the reset spring far from the driving motor is fixed to the outer side wall of the mounting frame far from the soil loosening roller, and the other end of the reset spring is fixed to the inner wall of the limiting block near the mounting frame.

[0016] Preferably, there are two groups of plow knife groups. The two groups of plow knife groups are respectively located on the front and rear sides of the soil loosening roller. The multiple plow knives of the two groups of plow knife groups are arranged in a staggered manner front and back, and both groups of plow knife groups are arranged towards the advancing direction of the vehicle.

[0017] In summary, the technical effects and advantages of the present utility model are as follows:

[0018] 1. In the present utility model, through the provision of the pushing protrusion and the reset member, during the forward movement of the vehicle, the driving motor drives the soil loosening roller to rotate, so that the pushing protrusion rotates accordingly and abuts against or separates from the movable connecting member. When the pushing protrusion abuts against the movable connecting member, it drives the plow knife group to slide towards the side close to the driving motor. When the pushing protrusion separates from the movable connecting member, the plow knife group slides towards the side away from the driving motor under the action of the reset member, thereby causing the plow knife group to generate a reciprocating swing during the forward movement of the vehicle, so as to perform arc-shaped cutting on the soil, which can enhance the damage effect of the plow knife group on the soil, make the soil form smaller soil blocks after being cut, and at the same time, the formed soil blocks have lower structural strength and are easier to be broken by the soil loosening roller. In this way, the soil forms a more uniform and loose soil structure after being plowed by the plow knife group and broken by the soil loosening roller, significantly improving the soil loosening effect of the soil loosening device for chrysanthemum planting.

[0019] 2. In the present utility model, through the provision of the movable rod and the reset spring, when the pushing protrusion separates from the connecting side plate, the connecting side plate moves towards the side away from the driving motor under the elastic force of the reset spring, thereby driving the plow knife group to reset, cooperating with the pushing protrusion to drive the plow knife group to perform a reciprocating swing, and finally achieving a better soil loosening effect.

[0026] 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Embodiment: Refer to Figures 1-4 A soil loosening device for chrysanthemum planting as shown, which includes a mounting frame 1 installed on a vehicle. A soil loosening roller 2 is rotatably installed between the side frames of the mounting frame 1, and a driving motor 6 for driving the rotation of the soil loosening roller 2 is fixed at one end of the mounting frame 1;

[0028] On the forward direction side of the soil loosening roller 2, there is a tillage knife group 3. The tillage knife group 3 is slidably connected to the mounting frame 1 through a movable connecting piece, and the sliding direction of the tillage knife group 3 is the same as the axial direction of the soil loosening roller 2;

[0029] One side of the soil loosening roller 2 is fixed with a pushing protrusion 7. The pushing protrusion 7 repeatedly abuts against or separates from the movable connecting piece as the soil loosening roller 2 rotates. When the pushing protrusion 7 abuts against the movable connecting piece, it drives the tillage knife group 3 to slide towards the side close to the driving motor 6;

[0030] Therefore, a resetting member is installed inside the mounting frame 1. When the pushing protrusion 7 separates from the movable connecting piece, the resetting member drives the tillage knife group 3 to slide towards the side away from the driving motor 6.

[0031] Based on the above structure, during the forward movement of the vehicle, the driving motor 6 drives the rotation of the soil loosening roller 2, so that the pushing protrusion 7 rotates accordingly and abuts against or separates from the movable connecting piece. When the pushing protrusion 7 abuts against the movable connecting piece, it drives the tillage knife group 3 to slide towards the side close to the driving motor 6. When the pushing protrusion 7 separates from the movable connecting piece, the tillage knife group 3 slides towards the side away from the driving motor 6 under the action of the resetting member. In this way, the tillage knife group 3 generates a reciprocating swing during the forward movement of the vehicle, thereby performing an arc-shaped cutting on the soil, which can enhance the damage effect of the tillage knife group 3 on the soil, making the soil form smaller soil blocks after being cut, and at the same time, the formed soil block structure has lower strength and is easier to be broken by the soil loosening roller 2. In this way, the soil forms a more uniform and loose soil structure after being plowed by the tillage knife group 3 and broken by the soil loosening roller 2, significantly improving the soil loosening effect of the soil loosening device for chrysanthemum planting.

[0032] It should be noted that multiple pushing protrusions 7 are provided (refer to Figure 1 and Figure 2 ), and the multiple pushing protrusions 7 are circumferentially distributed along the axis of the soil loosening roller 2. The distribution can be a regular distribution with equal intervals or an irregular distribution with random intervals ( Figure 1The bit rule distribution is shown (the irregular distribution is not shown), so that the pushing protrusion 7 can drive the plow knife group 3 to swing reciprocally in an orderly or disorderly manner, meeting the diverse requirements for tilling and loosening the soil;

[0033] Similarly, multiple pushing protrusions 7 can also be set to have different sizes ( Figure 1 In it, the pushing protrusions 7 have the same size, and the pushing protrusions 7 with different sizes are not shown), that is, the protruding lengths of the pushing protrusions 7 are different, so that the multiple pushing protrusions 7 can cause the distance of the plow knife group 3 to change when moving reciprocally, thus being more conducive to finely tilling the soil and further improving the tilling and soil loosening effect.

[0034] Furthermore, the movable connecting piece includes connecting side plates 5. There are two connecting side plates 5, which are respectively fixed to both ends of the plow knife group 3 through the mounting rods 4, and the middle parts of the connecting side plates 5 are movably sleeved on the shaft of the soil loosening roller 2;

[0035] During the rotation process, the pushing protrusion 7 abuts against or separates from the side of the connecting side plate 5 close to the soil loosening roller 2, and the resetting member is installed on the side of the connecting side plate 5 far from the soil loosening roller 2.

[0036] Among them, the resetting member includes a movable rod 8 and a reset spring 9. The movable rod 8 is fixed to the side of the connecting side plate 5 far from the soil loosening roller 2. One end of the movable rod 8 far from the connecting side plate 5 slides through the mounting frame 1, the reset spring 9 is sleeved on the movable rod 8, and the connecting side plate 5 is elastically connected to the mounting frame 1 through the movable rod 8 and the reset spring 9.

[0037] Through the arrangement of the movable rod 8 and the reset spring 9, when the pushing protrusion 7 separates from the connecting side plate 5, the connecting side plate 5 moves toward the side away from the driving motor 6 under the elastic force of the reset spring 9, thereby driving the plow knife group 3 to reset, cooperating with the pushing protrusion 7 to drive the plow knife group 3 to swing reciprocally, and finally achieving a better soil loosening effect.

[0038] Furthermore, a limiting block 81 is formed at one end of the movable rod 8 far from the connecting side plate 5. The diameter of the limiting block 81 is larger than the diameter of the movable rod 8. The limiting block 81 is located on the side of the mounting frame 1 far from the connecting side plate 5. The limiting block 81 can limit the movement stroke of the movable rod 8, that is, limit the movement formation of the connecting side plate 5, avoiding the connecting side plate 5 from colliding violently with the side wall of the soil loosening roller 2 under the elastic force of the reset spring 9, thereby avoiding damage to the soil loosening roller 2 and the connecting side plate 5, ensuring the safety of the device itself, and improving the reliability of the soil loosening device for chrysanthemum planting.

[0039] Even further, one end of the reset spring 9 close to the driving motor 6 is fixed to the side of the connecting side plate 5 close to the driving motor 6, and the other end of the reset spring 9 is fixed to the inner side of the mounting frame 1 close to the soil loosening roller 2. This reset spring 9 is a compression spring;

[0040] One end of the return spring 9 away from one end of the drive motor 6 is fixed to the outer wall of the mounting frame 1 away from the soil loosening roller 2, and the other end of the return spring 9 is fixed to the inner wall of the limiting block 81 close to the mounting frame 1. The return spring 9 is a tension spring.

[0041] By adopting different installation methods for the two return springs 9 and springs with different properties, the springs on both sides generate elastic forces towards the same side, thus more powerfully driving the connecting side plate 5 to reset. At the same time, it avoids hindering the movement of the connecting side plate 5 to both sides, ensuring its reset effect while facilitating the movement of the connecting side plate 5.

[0042] Furthermore, there are two sets of tillage knife groups 3, which are respectively located on the front and rear sides of the soil loosening roller 2. The multiple tillage knives of the two sets of tillage knife groups 3 are arranged in a staggered manner front and back, and both sets of tillage knife groups 3 are arranged towards the advancing direction of the vehicle. By using the two sets of tillage knife groups 3, the soil can be turned over twice, and the turning is more uniform and comprehensive, thereby further improving the soil loosening effect of the soil loosening device for chrysanthemum planting, and the actual use effect is better.

[0043] The working principle of the present utility model: During daily use, when the vehicle advances, the drive motor 6 drives the soil loosening roller 2 to rotate, so that the pushing protrusion 7 rotates accordingly and abuts against or separates from the connecting side plate 5. When the pushing protrusion 7 abuts against the connecting side plate 5, it drives the tillage knife group 3 to slide towards the side close to the drive motor 6. When the pushing protrusion 7 separates from the connecting side plate 5, the tillage knife group 3 slides towards the side away from the drive motor 6 under the elastic force of the return spring 9, so that the tillage knife group 3 generates a reciprocating swing during the process of advancing with the vehicle, thereby performing an arc-shaped cutting on the soil, which can enhance the damage effect of the tillage knife group 3 on the soil, making the soil form smaller soil blocks after being cut, and at the same time, the formed soil blocks have lower structural strength and are easier to be broken by the soil loosening roller 2. In this way, the soil forms a more uniform and loose soil structure after being plowed by the tillage knife group 3 and broken by the soil loosening roller 2, significantly improving the soil loosening effect of the soil loosening device for chrysanthemum planting.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
