[0015] By means of the above technical solution, the present invention provides a base fertilizer application device for Castanopsis chinensis planting, which has at least the following beneficial effects:

[0016] 1. The base fertilizer application device for Castanopsis chinensis planting can adjust the amount of base fertilizer added according to the slope of the planting location by setting a material control mechanism. In areas with a slope greater than 20°, 15%-25% base fertilizer (such as a combination of organic fertilizer and slow-release fertilizer) is added to compensate for soil and water loss and ensure that the root system (the main root depth of Castanopsis chinensis is 1-1.5 meters) absorbs sufficient nutrients. In areas with a slope less than 10°, the amount of chemical fertilizer is reduced by 10%-15% to avoid fertilizer damage caused by strong water retention capacity (Cassia chinensis is resistant to barrenness, but excessive nitrogen fertilizer can easily cause excessive growth).

[0017] 2. The base fertilizer application device for Castanopsis chinensis planting is provided with a pushing mechanism 300, which can backfill a corresponding amount of soil according to the amount of base fertilizer added. The backfill soil (volume ratio) is matched with the base fertilizer amount (such as 10-30 kg / plant of organic fertilizer) at 1:3-1:5 to form a fertilizer sandwich layer (20-40 cm from the ground surface), which not only avoids root burn but also ensures rapid root absorption.

[0018] 3. The base fertilizer application device for Castanopsis truncatum planting can also adjust the amount of material discharged according to the slope of the downhill slope, and convert the inclination angle (slope) of the vehicle body into the displacement of the sealing block. No external sensor or electronic control system is required, and the amount of fertilizer applied can be dynamically adjusted according to the slope, avoiding the problems of excessive fertilizer on steep slopes (easy to lose) or insufficient fertilizer on gentle slopes (affecting growth) caused by traditional fixed fertilization, so that the amount of fertilizer is accurately matched with the root distribution of Castanopsis truncatum and the soil's fertilizer retention capacity.

[0019] 4. The base fertilizer application device for Castanopsis chinensis planting can adjust the amount of fertilizer added according to the slope both uphill and downhill. When going uphill, rack one works (upper meshing), and when going downhill, rack two works (lower meshing), forming a two-way slope adaptation, covering the slope range of 15° to 45°, and further improving the quality of added fertilizer.

[0020] 5. The base fertilizer application device for Castanopsis chinensis planting can realize linkage operation and does not require the addition of sensors to sense terrain differences separately, further improving the quality of backfill soil and dynamically balancing the amount of backfill soil and fertilizer application. It can maintain the soil compaction of the planting pit, reduce the problem of compaction caused by excessive backfilling or fertilizer leakage caused by insufficient backfilling, and enhance the soil's ability to retain water and fertilizer.

[0021] 6. The base fertilizer application device for Castanopsis chinensis planting uses a motor to drive the transmission shaft to rotate forward and reverse, and the transmission shaft drives the material guide box to swing, which will evenly add fertilizer to different positions of the pit, so that the fertilizer forms a parabolic trajectory with a dynamically balanced inclination angle in the pit, avoiding local salt concentration overload in the root system and reducing the incidence of root burn.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The following describes a base fertilizer application device for Castanopsis truncatula planting provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0036] Example 1:

[0037] In planting environments with different slopes, such as mountainous areas, the distribution and loss of fertilizers vary significantly. Fertilizers on steep slopes are easily lost with rainwater or runoff. If fertilizers are applied according to the amount applied on flat land or gentle slopes, it will not only cause fertilizer waste, but may also lead to soil and water pollution. In order to solve the above problems, combined with Figure 1-Figure 4As shown, the base fertilizer application device for planting tung oil tree provided by the present invention includes a vehicle body 100, a hopper 101 is fixedly connected to the vehicle body 100, and a material control mechanism 200 for controlling the amount of material discharged is installed at the hopper 101. The amount of base fertilizer added can be adjusted according to the slope of the planting location. In areas with a slope greater than 20°, 15%-25% base fertilizer (such as a combination of organic fertilizer and slow-release fertilizer) is added to compensate for soil erosion and ensure that the root system (the main root depth of tung oil tree is 1-1.5 meters) absorbs sufficient nutrients. In areas with a slope less than 10°, 15%-25% base fertilizer (such as a combination of organic fertilizer and slow-release fertilizer) is added to compensate for soil erosion and ensure that the root system (the main root depth of tung oil tree is 1-1.5 meters) absorbs sufficient nutrients. The vehicle 100 can reduce the use of chemical fertilizers by 10%-15% in the field and avoid fertilizer damage caused by strong water retention capacity (the Chinese tallow tree is resistant to poor soil conditions, but excessive nitrogen fertilizer can easily cause excessive growth). The vehicle body 100 is provided with a pushing mechanism 300 for filling soil. It can backfill the corresponding amount of soil according to the amount of base fertilizer added. The backfill soil (volume ratio) is matched with the base fertilizer amount (such as 10-30kg / plant of organic fertilizer) at a ratio of 1:3-1:5, forming a fertilizer sandwich layer (20-40cm from the ground surface), which not only avoids root burn but also ensures rapid root absorption.

[0038] Since the existing equipment cannot adjust the feeding method according to the tilt state of the vehicle body 100, direct feeding when the vehicle is tilted will cause the fertilizer to accumulate on one side of the pothole, resulting in uneven fertilizer distribution. This will lead to large differences in nutrient concentration around the plant roots. Some roots may be damaged due to excessive fertilizer concentration, while some roots may grow poorly due to lack of nutrients, affecting the overall growth condition and yield of the plants. In order to solve the above problems, a shell 201 is installed on the vehicle body 100, and a slide rail 20 is fixed inside the shell 201. 2. A ball 203 is slidably connected to the slide rail 202. Springs 204 are fixed to both side walls of the slide rail 202. An arc block 205 is installed on the spring 204. The two arc blocks 205 are respectively fixed to connecting bars 206 that are slidably connected to the slide rail 202. A rotating shaft 220 is rotatably installed on the side of the housing 201 away from the silo 101. A winding roller 209 is fixedly mounted on the rotating shaft 220. The material control mechanism 200 includes a sealing block 212 that is slidably connected to the discharge port of the silo 101.A transmission rope 211 is wound around the winding roller 209 for pulling the sealing block 212 to move. A spur gear 208 is mounted on the rotating shaft 220. The spur gear 208 and the winding roller 209 are staggered. The winding roller 209 is close to the sealing block 212. The two connecting bars 206 are respectively provided with a rack 207 and a rack 210 that mesh with the spur gear 208. An L-shaped bar 214 is fixed to the sealing block 212. An electric push rod 213 is installed on the silo 101 for pushing the sealing block 212 to reset. When the vehicle body 100 travels at different slopes, the vehicle body 100 There will be different degrees of inclination. When going uphill, the rack 1 207 at the upper position is engaged with the spur gear 1 208, and the rack 210 at the lower position is not engaged with the spur gear 1 208. Since the vehicle body 100 is in an inclined state, when it reaches the pothole position, the free end of the electric push rod 1 213 contracts and no longer generates thrust on the sealing block 212 on the L-shaped bar 214. The sealing block 212 can be removed from the discharge port. At the same time, the ball 203 will roll to one side. Due to the provision of the spring 204, the ball 203 will generate different degrees of thrust on the curved plate according to the degree of inclination, that is, the size of the slope. The thrust of the connecting strip 206 on the arc plate drives the rack 207 to move, and the movement of the rack 207 drives the spur gear 208 to rotate, and the rotation of the spur gear 208 drives the rotating shaft 220 to rotate, and the winding roller 209 rotates along with the rotating shaft 220. The rotation of the winding roller 209 will wind the transmission rope 211, and the transmission rope 211 pulls the sealing block 212 to move. The position of the sealing block 212 can be adjusted according to the size of the slope, and the size of the discharge port can be changed, so that the amount of discharge can be adjusted according to the size of the slope. The longer the sealing block 212 moves, the more material is discharged, and vice versa. When traveling downhill, rack 210 at the bottom meshes with spur gear 1 208, while rack 1 207 at the top does not. Based on the same operating principle as above, the amount of material discharged can be adjusted according to the gradient of the downhill slope, converting the tilt angle (slope) of vehicle body 100 into the displacement of sealing block 212. Without the need for external sensors or electronic control systems, the amount of fertilizer applied can be dynamically adjusted based on the slope, avoiding the problems of traditional fixed fertilization, such as excessive fertilizer application on steep slopes (easily lost) or insufficient fertilizer application on gentle slopes (affecting growth). This ensures that the amount of fertilizer is precisely matched to the root distribution of the Chinese tallow tree and the soil's fertility retention capacity.

[0039] Mountain ash is mostly planted in terraced fields, ridges and other complex terrains. Two-way adjustment can avoid "lack of fertilizer on the uphill and fertilizer damage on the downhill". For example, the test in Zhaotong, Yunnan, showed that fertilizer loss in the downhill area was reduced by 62%. In order to solve the above problem, the two connecting bars 206 are fixed with a frame 216, and a screw 215 is rotatably installed in the frame 216. The two screws 215 are respectively threadedly connected to the rack 1 207 and the rack 210, and the rack 1 207 and the rack 210 are respectively slidably connected to the frame 216. The staff adjusts the frame 216 according to the terrain differences. When going uphill or downhill, the corresponding screw 215 is rotated respectively, and the screw 215 will drive the corresponding rack 1 207 and rack 2 210 to move, so that the rack 1 207 and rack 2 210 are staggered and meshed with the spur gear 1 208. The amount of fertilizer added can be adjusted according to the slope size both uphill and downhill. When going uphill, the rack 1 207 works (meshing at the top), and when going downhill, the rack 2 210 works (meshing at the bottom), forming a two-way slope adaptation, covering the slope range of 15° to 45°, and further improving the quality of added fertilizer.

[0040] According to the embodiment, after adding fertilizer, the free end of the electric push rod 213 extends to push the sealing block 212 on the L-shaped bar 214 to reset, and the above steps are repeated. When the next pothole is reached, fertilizer can continue to be added.

[0041] Example 2:

[0042] In mountainous environments with different slopes, the distribution and loss of fertilizers show significant differences: on steep slopes (>25°), the fertilizer loss rate is as high as 35%-50% due to the fast runoff velocity (0.5-1.2m / s), and gravity causes fertilizer deficiency on the upper slope (root zone concentration <40% of the design value) and fertilizer damage on the lower slope (EC value exceeds the threshold of 60%); on gentle slopes (15°-25°), the runoff velocity is 0.2-0.5m / s, the loss rate is 15%-25%, and it is easy to have a strip distribution of phosphorus deficiency (<80mg / kg) on the upper slope and nitrogen excess (>150mg / kg) on the lower slope. In order to solve the above problems, combined with Figure 5 and Figure 6 As shown, on the basis of embodiment 1, the bottom wall of the vehicle body 100 is fixedly connected to the limit frame 302, and a connecting shaft 307 is rotatably installed on the limit frame 302. The bottom of the connecting shaft 307 is fixedly connected to a screw rod 303, and the screw rod 303 is threadedly connected to a guide plate 301 that is slidably connected to the limit frame 302. Since the soil will be piled on one side when digging a pit, according to the amount of base fertilizer added, the screw rod 303 rotates to drive the guide plate 301 to move. When the guide plate 301 moves downward, the subsequent movement of the vehicle body 100 will drive the guide plate 301 to move. The greater the downward movement distance of the guide plate 301, the more fertilizer is added, and vice versa, the less, so that the corresponding amount of soil can be pushed back into the pit according to the amount of base fertilizer, thereby realizing the quantitative ratio of base fertilizer and backfill soil, ensuring that the fertilizer is evenly wrapped by the soil, avoiding volatilization and leaching losses caused by fertilizer exposure, and improving fertilizer utilization.

[0043] The sensor is easily contaminated by dust, mud and water in the mountain environment, which leads to reduced reliability, delays in signal acquisition and processing, and requires regular manual calibration. In order to solve the above problems, a spur gear 2 304 is fixed to the top of the connecting shaft 307, and a rack 305 is provided on the vehicle body 100 for meshing with the spur gear 2 304. The rack 305 is slidably connected to the vehicle body 100 through the slide groove 2 310. A push rod 308 is fixed to the side of the sealing block 212 close to the rack 305, which is used to push the rack 305 to move. The vehicle body 100 is also provided with an electric push rod 2 306 for pushing the rack 305 to reset. When the sealing block 212 moves, it will also push the top push rod 308 to reset the rack 305. The rod 308 pushes the rack three 305 to move. When the rack three 305 moves, it drives the screw rod 303 on the connecting shaft 307 to rotate through the spur gear two 304. The rotation of the screw rod 303 will drive the guide plate 301 to move. The descending distance of the guide plate 301 can be adjusted according to different slope sizes, and the corresponding amount of soil can be backfilled according to the amount of fertilizer added. It can also achieve linkage operation and does not need to add sensors to sense the terrain difference alone. The quality of the backfill soil is further improved, and the amount of backfill soil and the amount of fertilizer applied are dynamically balanced. The soil compaction of the planting pit can be maintained, and the problem of compaction caused by excessive backfilling or fertilizer leakage caused by insufficient backfilling can be reduced, thereby enhancing the soil's ability to retain water and fertilizer.

[0044] Furthermore, a protective cover 309 is fixed to the vehicle body 100 , the second electric push rod 306 is installed on the protective cover 309 , the third rack 305 and the second spur gear 304 are located inside the protective cover 309 , and the push rod 308 passes through the protective cover 309 and is slidably connected to the protective cover 309 .

[0045] According to the examples, a moderate soil cover thickness (matching the amount of base fertilizer) can prevent excessive fertilizer concentration from burning the roots ("root burn"), while keeping the soil loose and breathable, providing a stable microenvironment for the development of the Castanopsis tung tree root system.

[0046] Example 3:

[0047] Because the vehicle is in an inclined state, when the material is directly discharged, the fertilizer will accumulate on one side of the pit, and the fertilizer distribution will be seriously uneven, causing the local fertilizer concentration of the plant root to be overloaded, causing root burn and root rot. Figure 5 and Figure 7As shown, on the basis of Example 1, a guide hopper 102 located below the discharge port of the silo 101 is fixedly connected to the vehicle body 100, and a motor 103 is also fixedly installed on the bottom wall of the vehicle body 100. The output end of the motor 103 is fixedly connected to a transmission shaft 104, and a guide box 105 is fixedly connected to the transmission shaft 104. A soft edge 106 is bonded between the discharge port of the guide box 105 and the guide hopper 102. The soft edge 106 forms a sealed channel between the discharge port of the guide box 105 and the guide hopper 102. The added fertilizer will first enter the guide hopper 102, and the motor 103 drives the transmission shaft 104 to rotate forward and reverse, and the transmission shaft 104 drives the guide box 105 to swing, which will evenly add fertilizer to different positions of the pit, so that the fertilizer forms a parabolic trajectory with a dynamically balanced inclination angle in the pit, thereby avoiding local salt concentration overload of the root system and reducing the incidence of root burn.

[0048] According to the embodiment, direct feeding of fertilizer while the vehicle is tilted will cause the fertilizer to accumulate on one side of the pothole, resulting in extremely uneven fertilizer distribution. However, the swinging feeding of the guide box 105 can disperse the fertilizer more evenly within the pothole, preventing localized excessive fertilizer concentration and the "root burn" phenomenon that may affect plant roots, thereby improving the efficiency of fertilizer absorption by plant roots.

[0049] Example 4:

[0050] Combine Figure 1-Figure 3 As shown, based on Example 1, a U-shaped frame 217 is fixed at the discharge port of the silo 101, the sealing block 212 is slidingly connected to the U-shaped frame 217 through a slide groove 219, and the L-shaped bar 214 passes through the U-shaped frame 217 and is slidingly connected to the U-shaped frame 217.

[0051] Specifically, the L-shaped bar 214 and the electric push rod 1 213 are located in the same plane, and a protective pad is fixed to the end of the electric push rod 1 213 to protect the components.

[0052] Furthermore, the end of the screw rod 215 extends to the outside of the frame 216 and is fixedly connected to a rotating block 218 . The staff rotates the rotating block 218 to facilitate the rotation of the screw rod 215 .

[0053] An inspection door is provided on the housing 201 , and a handle is fixedly connected to the inspection door. The inspection door is opened to facilitate inspection of components inside the housing 201 .

[0054] It can be seen from the above embodiments that: the staff pre-adjusts the corresponding screw 215 according to the terrain. When the vehicle body 100 tilts up or downhill, the rolling ball 203 is rolled to the lower position by gravity to squeeze the spring 204, and pushes the connecting bar 206 through the arc block 205: when going uphill, the upper rack 1 207 is engaged with the spur gear 1 208, and the movement of the rack drives the rotation shaft 220 to rotate, and the winding roller 209 wraps around the transmission rope 211 to pull the sealing block 212 to open the discharge port; when going downhill, the lower rack 210 is engaged, and the opening of the sealing block 212 is adjusted in the opposite direction. After reaching the pit position, the electric push rod 1 213 contracts and releases the sealing block 212, and the fertilizer falls through the discharge port with precise opening, converting the slope into displacement of the sealing block 212, realizing two-way dynamic material control up and downhill. After the operation, the electric push rod resets the sealing block 212, and the spring 204 eliminates the transmission gap, completing the full mechanical process of "pre-adjusting screw 215 → slope sensing → rack switching → sealing and material control → reset cycle". It can automatically adjust the amount of fertilizer according to the slope of 0° to 45° without the need for sensors, solving the problems of fertilizer shortage on uphill slopes and fertilizer damage on downhill slopes, and realizing precise fertilization in all terrains of mountains.
