Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment, specifically to an integrated machine for reseeding, fertilizing, and compacting slope grassland. Background Technology

[0002] Sloping grasslands are natural or artificial landforms with unique topography and vegetation cover, typically located on hillsides or slopes, where vegetation cover is usually sparse. The living environment for plants on sloping grasslands is more challenging than that of flat grasslands. In recent years, the degradation of sloping grasslands has become more severe, mainly manifested in increased soil erosion, deterioration of soil physical properties, reduced soil fertility, decreased forage production capacity, and a decline in grass species. These changes not only affect the ecological functions of the grasslands but also impact surrounding livestock production, making artificial reseeding and restoration of sloping grasslands extremely important.

[0003] Because sloping grasslands have a certain slope, sometimes exceeding 60°, existing large-scale reseeding, fertilizing, and compacting machines struggle to operate stably on these slopes. Currently, sloping grasslands are typically managed manually by broadcasting, fertilizing, and compacting, resulting in a time-consuming, labor-intensive, and inefficient process. Furthermore, sloping grasslands are prone to windy weather; during manual reseeding and fertilizing, freshly sown seeds and fertilizer are often blown down the slope, or even in calm conditions, the slope causes seeds to roll downhill, resulting in waste. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated machine for reseeding, fertilizing, and compacting on sloping grasslands. It has a simple structure, is easy to operate, can work on sloping grasslands, and can prevent the sown seeds and fertilizers from being blown away or blown down the slope.

The pressing roller is used to press down the seeds or fertilizer introduced into the ground.

[0010] In an optional embodiment, the feeding unit further includes an elastic element that is sleeved outside the discharge pipe and abuts against the feeding roller and the movable cover, and causes the movable cover to tend to move relative to the discharge pipe toward a position away from the feeding roller and outside the discharge pipe.

[0011] In an optional embodiment, the movable cover includes a main body, two cover plates and two return springs. The main body is sleeved on the discharge pipe and abuts against the elastic element. The two cover plates are rotatably connected to the main body.

[0012] Both return springs are connected to the main body and to the two cover plates respectively, so that the two cover plates have a tendency to move toward each other to cover the discharge pipe.

[0013] In an optional implementation, the discharge port is located at the end of the discharge pipe away from the feeding roller.

[0014] In an optional embodiment, the discharge port is located on the outer peripheral surface of the discharge pipe, and the outer peripheral surface of the discharge pipe is provided with a guiding groove, which extends from the position of the discharge port toward the end of the discharge pipe away from the feeding roller.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] Sloping grasslands are natural or artificial landforms with unique topography and vegetation cover, typically located on hillsides or slopes, where vegetation cover is usually sparse. The living environment for plants on sloping grasslands is more challenging than that of flat grasslands. In recent years, the degradation of sloping grasslands has become more severe, mainly manifested in increased soil erosion, deterioration of soil physical properties, reduced soil fertility, decreased forage production capacity, and a decline in grass species. These changes not only affect the ecological functions of the grasslands but also impact surrounding livestock production, making artificial reseeding and restoration of sloping grasslands extremely important.

[0042] Because sloping grasslands have a certain slope, sometimes exceeding 60°, existing large-scale reseeding, fertilizing, and compacting machines struggle to operate stably on these slopes. Currently, sloping grasslands are typically managed manually by broadcasting, fertilizing, and compacting, resulting in a time-consuming, labor-intensive, and inefficient process. Furthermore, sloping grasslands are prone to windy weather; during manual reseeding and fertilizing, freshly sown seeds and fertilizer are often blown down the slope, or even in calm conditions, the slope causes seeds to roll downhill, resulting in waste.

[0043] For the reasons mentioned above, please refer to Figures 1-5 This embodiment provides an integrated machine 100 for reseeding, fertilizing, and compacting on sloping grasslands. It can compact the soil during reseeding and fertilizing on sloping grasslands, allowing the seeds and fertilizers to be tightly bound to the soil, thereby preventing the seeds and fertilizers from being blown away or blown down the slope. In this embodiment, the seeds or fertilizers are inserted into the soil to a depth of 3cm to reduce waste. In other embodiments of this utility model, the insertion depth of the seeds and fertilizers can be adjusted.

[0044] Specifically, the integrated machine 100 for reseeding, fertilizing and compacting grassland includes a frame 110, a seeding roller 120, a compaction roller 130 and multiple feeding units 140.

[0045] Both the feeding roller 120 and the pressing roller 130 are rotatably connected to the frame 110 and move along a preset forward direction (e.g., ...). Figure 1 (In the direction indicated by the middle arrow A), the feeding roller 120 is located in front of the pressing roller 130;

[0046] The seeding roller 120 has multiple hoppers 121 for holding seeds or fertilizers, and the multiple hoppers 121 are distributed at intervals around the axis of the seeding roller 120; multiple feeding units 140 are connected to the outer periphery of the seeding roller 120 around the axis of the seeding roller 120, and each feeding unit 140 is connected to a corresponding hopper 121.

[0047] The feeding unit 140 is used to press the seed or fertilizer in the corresponding hopper 121 into the ground as the feeding roller 120 rolls relative to the ground; the pressing roller 130 is used to press the seed or fertilizer into the ground.

[0048] Please refer to Figures 1-5 The working principle of the 100-ton integrated machine for reseeding, fertilizing, and compacting grassland on this slope is as follows:

[0049] The integrated machine 100 for reseeding, fertilizing, and compacting sloping grassland includes a frame 110, seeding rollers 120, compaction rollers 130, and multiple feeding units 140. Both the seeding rollers 120 and the compaction rollers 130 are rotatably connected to the frame 110, allowing for seed and fertilizer application through manual movement of the frame 110 during sloping grassland construction. Furthermore, a drive unit can be added to drive one or both of the seeding rollers 120 and the compaction rollers 130, reducing the intensity of manual labor.

[0050] Furthermore, the operation is illustrated using manual pushing as an example. Along the preset forward direction, the seeding roller 120 is located in front of the compaction roller 130. The purpose is to first send out the seeds and fertilizer when sowing one or both through the seeding roller 120, and then compact them through the compaction roller 130, so that the sown seeds and fertilizer are tightly compacted in the soil. Combined with the depth of insertion, this can improve the success rate of seed and fertilizer sowing, avoid the situation of seeds and fertilizer not being sown in place, and reduce the waste of seeds and fertilizer.

[0051] Furthermore, during the operation of the integrated reseeding, fertilizing, and compacting machine 100 for slope grassland, the seeds and fertilizer to be sown are placed in the sowing roller 120, and then the frame 110 is pushed to make the sowing roller 120 roll relative to the slope grassland, thereby continuously sowing the seeds or fertilizer into the soil. Based on this, this embodiment adopts a method in which multiple hoppers 121 for holding seeds or fertilizer are built into the sowing roller 120. The multiple hoppers 121 are distributed at intervals around the axis of the sowing roller 120. In this way, the seeds and fertilizer to be sown can be pre-stored in the sowing roller 120, and then, as it rolls on the slope grassland, the pre-stored seeds and fertilizer can be sown into the soil of the slope grassland. Moreover, this method can reduce the frequency of adding seeds and fertilizer, which is beneficial to improving the work efficiency.

[0052] Multiple feeding units 140 are connected to the outer periphery of the feeding roller 120 around the axis of the feeding roller 120, and each feeding unit 140 is connected to a corresponding hopper 121. The feeding unit 140 is arranged so that it protrudes relative to the feeding roller 120, so that the feeding unit 140 can be pressed into the ground as the feeding roller 120 rolls relative to the ground, with a depth of 3cm. At the same time as it is pressed into the ground, it can also guide the seeds or fertilizer in the corresponding hopper 121 into the pressed ground.

[0053] As the frame 110 continues to operate, when the pressing roller 130 passes over the ground where seeds or fertilizer have been sown, the seeds or fertilizer introduced into the ground can be pressed by the pressing roller 130.

[0054] In summary, the 100 integrated machine for reseeding, fertilizing, and compacting grassland is simple in structure and easy to operate. It can work on grassland slopes and prevent the sown seeds and fertilizers from being blown away or down the slope. It can also improve the efficiency of sowing and fertilizing and reduce labor costs.

[0055] Further, please refer to Figures 1-12 In this embodiment, the feeding unit 140 includes a discharge pipe 141 and a movable cover 142; the discharge pipe 141 is connected to the feeding roller 120 and extends radially along the feeding roller 120, and communicates with the corresponding hopper 121; the discharge pipe 141 is provided with a discharge port 143; the movable cover 142 is movably sleeved on the outside of the discharge pipe 141;

[0056] The movable cover 142 is used to cover the outside of the discharge pipe 141 when it is not in contact with the ground (e.g., Figure 4 , Figure 7 , Figure 8 and Figure 9(As shown); the movable cover 142 is also used to move relative to the discharge pipe 141 toward the feeding roller 120 when inserted into the ground, and to at least open the end of the discharge pipe 141 away from the feeding roller 120 (as shown). Figure 6 , Figure 10 , Figure 11 and Figure 12 As shown), so that the seeds or fertilizer in the hopper 121 are discharged to the inserted ground through the discharge pipe 141 and the discharge port 143.

[0057] Thus, through the above-mentioned structural arrangement, as the seeding roller 120 rolls relative to the ground, multiple feeding units 140 can continuously contact the ground and be pressed into the soil of the grass slope under the gravity of the seeding roller 120. In this embodiment, the pressing depth is 3cm. Moreover, during the pressing process, since the discharge pipe 141 is connected to the seeding roller 120 and its length remains unchanged, and the movable cover 142 is movably sleeved outside the discharge pipe 141, as the seeding roller 120 rolls, after the movable cover 142 contacts the ground, it will move relative to the discharge pipe 141 under the force of the ground soil, thereby exposing the end of the discharge pipe 141, and thus sowing seeds and fertilizers.

[0058] That is, taking the working process of one of the feeding units 140 as an example, after it comes into contact with the ground soil, the discharge pipe 141 will be pressed into the soil in the direction of insertion into the ground under the action of gravity. At this time, since the movable cover 142 is movably covered outside the discharge pipe 141, the movable cover 142 will move relative to the discharge pipe 141 towards the sowing roller 120 under the squeezing action of the soil, thereby opening at least one end of the discharge pipe 141 away from the sowing roller 120, so that the seeds or fertilizer in the hopper 121 can be discharged to the inserted ground through the discharge pipe 141 and the discharge port 143, thereby completing the sowing of seeds or fertilizer.

[0059] As the seeding roller 120 continues to rotate, after the aforementioned discharge pipe 141 pulls out of the soil, the movable cover 142 will return to the state of covering the end of the discharge pipe 141 away from the seeding roller 120, thereby preventing seeds or fertilizer from leaking out. That is, at this time, the movable cover 142 is not in contact with the ground and will cover the discharge pipe 141, thereby preventing seeds or fertilizer from spilling out.

[0060] Furthermore, in order to enable the movable cover 142 to open the end or other position of the discharge pipe 141 to release seeds or fertilizer when the ground soil of the slope grass is inserted, and to cover the discharge pipe 141 after it is pulled out of the soil and prevent the seeds or fertilizer from being spilled, the feeding unit 140 also includes an elastic member 144. The elastic member 144 is sleeved on the outside of the discharge pipe 141 and abuts against the seeding roller 120 and the movable cover 142, so that the movable cover 142 has a tendency to move relative to the discharge pipe 141 toward a position away from the seeding roller 120 and covered outside the discharge pipe 141.

[0061] That is, with this arrangement, when the discharge pipe 141 is inserted into the ground, the movable cover 142 will overcome the elastic force of the elastic element 144 under the pressure of the soil and move relative to the discharge pipe 141 toward the sowing roller 120, thereby opening at least one end of the discharge pipe 141 away from the sowing roller 120, so that the seeds or fertilizer in the hopper 121 can be discharged to the inserted ground through the discharge pipe 141 and the discharge port 143, thereby completing the sowing of seeds or fertilizer;

[0062] After the discharge pipe 141 is pulled out of the soil, the movable cover 142 will return to the state of covering the end of the discharge pipe 141 away from the seeding roller 120 under the elastic force of the elastic element 144, thereby preventing the seeds or fertilizer from leaking out. That is, at this time the movable cover 142 is not in contact with the ground, and it will be kept covered outside the discharge pipe 141 under the elastic force of the elastic element 144, thereby preventing the seeds or fertilizer from being spilled out.

[0063] Therefore, by setting the elastic element 144, the movable cover 142 can remain covered on the discharge pipe 141 without being subjected to the squeezing force of the soil. It can also prevent the discharge pipe 141 from being accidentally opened when the seeding roller 120 rotates to other positions, thus preventing the seeds or fertilizer from being accidentally spilled.

[0064] Based on the above structure, when configuring the movable cover 142, this embodiment adopts a movable cover 142 including a main body 145, two cover plates 146 and two return springs 147. The main body 145 is sleeved on the discharge pipe 141 and abuts against the elastic member 144. The two cover plates 146 are rotatably connected to the main body 145.

[0065] Both return springs 147 are connected to the main body 145 and to the two cover plates 146 respectively, so that the two cover plates 146 have a tendency to move towards each other to cover the discharge pipe 141.

[0066] Thus, through the above-described structural arrangement, the two cover plates 146 slide relative to the discharge pipe 141 under the pressure of the soil, and in this process, they can deflect relative to the elastic force of the return spring 147, thereby allowing the end of the discharge pipe 141 to be exposed so as to facilitate the dispensing of seeds or fertilizer.

[0067] Further, please refer to Figures 1-12 Based on the above-described structure of the feeding unit 140, there are various implementation methods for configuring the discharge port 143 of the discharge pipe 141, such as: Figure 4 and Figure 5 As shown, the discharge port 143 can be set at the end of the discharge pipe 141 away from the seeding roller 120. The purpose is to quickly discharge the seeds or fertilizer when the discharge pipe 141 is inserted into the ground.

[0068] like Figures 6-12 As shown, the discharge port 143 can also be located on the outer peripheral surface of the discharge pipe 141, and the outer peripheral surface of the discharge pipe 141 is provided with a guiding groove 148. The guiding groove 148 extends from the position of the discharge port 143 toward the end of the discharge pipe 141 away from the seeding roller 120. This arrangement can prevent the discharge port 143 from contacting the soil, thereby preventing the discharge port 143 from being blocked by the soil. Moreover, when discharging seeds or fertilizer, they are discharged through the guiding groove 148 on its outer periphery, thereby preventing the aforementioned movable cover 142 from blocking the discharge of seeds or fertilizer.

[0069] It should be noted that when configuring the feeding groove 148, it needs to be larger than the particle size of the seeds and fertilizers to avoid the seeds or fertilizers getting stuck.

[0070] Further, please refer to Figures 1-12 To facilitate the addition of seeds or fertilizer to each hopper 121, the feeding roller 120 is equipped with multiple feed ports 122 at one or both ends, each feed port 122 corresponding to a hopper 121. Furthermore, each feed port 122 is detachably connected to a hopper door 123, which is used to open or close the feed port 122. Thus, when replenishment is needed, the hopper door 123 at its end can be opened for replenishment; moreover, the hopper door 123 can be threadedly connected to the feed port 122 of the feeding roller 120 to prevent it from protruding from the end of the feeding roller 120, thereby avoiding interference with the frame 110.

[0071] To improve operational efficiency, the feeding roller 120 is equipped with multiple feed inlets 122 at both ends, and each hopper 121 corresponds to two feeding units 140. Along the axial direction of the feeding roller 120, the two feeding units 140 corresponding to the same hopper 121 are located at both ends of the hopper 121. Therefore, during operation, the two feeding units 140 corresponding to the same hopper 121 can work simultaneously and be replenished by the feed inlets 122 at both ends. Furthermore, to guide the material in the hopper 121 towards the two feeding units 140, i.e., to act as a guide within the hopper 121, the middle of the outer wall of each hopper 121 is bent towards the axial direction of the feeding roller 120 along the axial direction of the feeding roller 120. This guides the material within the hopper 121 towards both ends of the axial direction of the feeding roller 120, and subsequently towards the discharge pipe 141 of the corresponding feeding unit 140.

[0072] It should be noted that, in this embodiment, seeds or fertilizer, or a mixture of seeds and fertilizer, can be added to a single silo 121 according to time requirements. Moreover, during operation, the amount of seeds sown in a single run can be controlled and adjusted by the size of the discharge port 143 and its rolling speed. In addition, the size of the discharge port 143 on the discharge pipe 141 and the size of the movable cover 142 can also play a corresponding role in adjusting the amount of seeds sown in a single run. Furthermore, if it is necessary to make precise adjustments to the amount of seeds sown, a quantitative feeding control structure can be set in the discharge pipe 141 or at the connection between the discharge pipe 141 and the silo 121, the purpose of which is to precisely control the amount of seeds sown in a single run.

[0073] Furthermore, it should be noted that in other embodiments of this utility model, the difference from the above is that, in order to facilitate the simultaneous discharge of seeds and fertilizers, a partition can be provided in each hopper 121 to divide the hopper 121 into two sub-hoppers. The partition is located in the middle of the hopper 121, so that the two sub-hoppers are located on both sides of the partition. Each sub-hopper corresponds to a feeding unit 140, and the feeding unit 140 is arranged parallel to the axis of the feeding roller 120, so that the two feeding units 140 connected to the two hoppers 121 divided by the same hopper 121 can simultaneously contact or detach from the ground, thereby enabling the simultaneous discharge of seeds and fertilizers.

[0074] Based on this, in order to facilitate the addition of seeds and fertilizer to the two sub-compartments respectively, multiple feed ports 122 can be configured at both ends of the feeding roller 120, and each feed port 122 is connected to a sub-compartment, thereby facilitating the addition of seeds or fertilizer to the sub-compartment.

[0075] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
