[0002] When planting vegetables, it is usually necessary to renovate the original land. At first, the land was usually turned manually, but this method of turning the soil is too labor-intensive and has low work efficiency. Therefore, shovel-type tillers are usually used now.

[0003] The shovel-type tiller is specially used for loosening the soil in small farmland. It is mainly powered by a tractor. The middle bearing pulls several short arms to drive the bottom shovel to press into the soil alternately. The maximum digging depth can reach 40 cm. The staff can easily complete the loosening work by driving it around in the farmland. It not only increases the air permeability and water permeability of the soil, but also brings out the nutrient soil in the lower layer.

[0004] However, there are hard clods in some unrenovated lands, which are not only difficult to turn over by tillers, but also easily cause wear to the blades. Therefore, the existing needs are not met. We have proposed an anti-damage tilling device for vegetable planting. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: This embodiment is intended to help solve the problem of hard soil blocks in some unrenovated land. When a tiller is turning over such soil blocks, it is not only difficult to turn over, but also easy to cause wear and tear on the blade. Please refer to Figure 1-11A damage-proof soil turning device for vegetable planting includes a connecting rod 110 and a frame 111 at the rear side of a tractor. The frame 111 is installed at the other end of the connecting rod 110 by bolts. A driving shaft 112 is installed on the frame 111. A tractor transmission wheel 113 is installed in the middle of the driving shaft 112. A plurality of short arms 114 are installed on the driving shaft 112. A soil turning rod 115 is hinged at the other end of the short arm 114. A plow 116 for turning the soil is installed at the bottom end of the soil turning rod 115. A handle 117 is installed on the plow 116. A plow 116 is provided in the soil turning rod 115. A slot 118 is provided, and the handle 117 is inserted in the slot 118. A connecting rod 124 is installed on the top of the handle 117. A piston chamber 119 is provided in the tilling rod 115. The connecting rod 124 extends into the piston chamber 119. A piston block 120 is installed on the end of the connecting rod 124. An air intake passage 121 is provided in the tilling rod 115. The air intake passage 121 is connected with the piston chamber 119. An air intake check valve 122 is provided in the air intake passage 121. The piston block 120 is slidably inserted in the piston chamber 119. A spring 123 is installed between the handle 117 and the slot 118.

[0033] It should be noted that the tractor driving wheel 113 can be set as a pulley or a chain wheel, and the other end is connected to the power shaft of the tractor. The specific connection method is the existing technology and is well known to those skilled in the art.

[0034] See Figure 2-Figure 4 The frame 111 is provided with a limit assembly 130 for limiting the movement track of the tiller rod 115. The limit assembly 130 includes a fixed block 131 installed on the frame 111 and limit plates 132 installed on both sides of the tiller rod 115. A first fixed rod 133 is installed in the fixed block 131, and a second fixed rod 134 is inserted in the limit plate 132. A linkage plate 135 is hinged between the first fixed rod 133 and the second fixed rod 134. The linkage plate 135 is located outside the limit plate 132. A limit sleeve 136 is provided on the outer surface of the second fixed rod 134. The limit sleeve 136 contacts the outside of the tiller rod 115 to prevent the tiller rod 115 from excessively deflecting or shaking during movement. When the tiller rod 115 encounters the reaction force generated by the harder soil block and tries to deviate from the normal movement track, the limit sleeve 136 will block and limit the tiller rod 115, so that the tiller rod 115 returns to the normal movement path.

[0035] A support rod 137 is installed on the frame 111, and a plurality of support plates 149 are fixedly sleeved on the support rod 137. The plurality of support plates 149 are rotatably plugged with the drive shaft 112 at one end away from the support rod 137. A support block 139 for supporting the tractor drive wheel 113 is installed in the middle of the support rod 137. An arc groove 140 is provided on the side of the support block 139. The tractor drive wheel 113 contacts the arc groove 140. A channel for a belt (or chain) to pass through is opened in the support block 139, and the channel is connected to the arc groove 140.

[0036] The limiting assembly 130 in this embodiment can effectively limit the movement trajectory of the tiller bar 115 when the tractor drives the drive shaft 112 to rotate and the drive shaft 112 drives the tiller bar 115 to move through the short arm 114, thereby ensuring that the tiller bar 115 moves along the predetermined route.

[0037] The tillering rod 115 and the plow 116 are arranged in two groups, one group of tillering rod 115 and plow 116 is located on the side of the other group of tillering rod 115 and plow 116, a transmission shaft 125 is inserted in the tillering rod 115, one end of the short arm 114 is sleeved outside the drive shaft 112, and the other end of the short arm 114 is installed on the outside of the transmission shaft 125, the two groups of tillering rod 115 and plow 116 are alternately arranged on the drive shaft 112, and the two groups of tillering rod 115 and plow 116 have the same structure.

[0038] The two adjacent groups of tilling rods 115 and plow blades 116 are alternately pressed into the soil, and their forces on the soil are applied alternately. After the first group of tilling rods 115 and plow blades 116 have turned over a part of the soil, the second group of tilling rods 115 and plow blades 116 will then turn over the soil in the adjacent area, so that the soil can be more fully stirred and turned over, and the soil is looser, achieving a better tilling effect. At the same time, when the two groups of tilling rods 115 and plow blades 116 act alternately, the soil will collide and squeeze with each other during the turning process, making the soil easier to turn over, further improving the efficiency and quality of tilling.

[0039] In this embodiment: In this scheme, a connecting rod 124 is installed on the handle 117, and a piston block 120 is installed on the connecting rod 124. A piston cavity 119 is opened in the soil turning rod 115, and then through the cooperation of the piston block 120 and the spring 123, when the coulter 116 encounters a harder soil block during the soil turning process, the coulter 116 and the handle 117 will move into the slot 118, and at this time, the piston block 120 slides in the piston cavity 119, and the spring 123 is squeezed; Then, through the setting of the air intake channel 121 and the air intake check valve 122, the spring 123 is released when the plow blade 116 loses the resistance of the harder soil block. At this time, the spring 123 pushes the handle 117 and the plow blade 116 to reset. At the same time, the gas enters the piston chamber 119 through the air intake channel 121, pushing the piston block 120 to reset. As a result, when the tiller 116 encounters a harder soil block during operation, it can be shortened in time, effectively playing a buffering effect, while reducing the wear of the plow blade 116, thereby improving the service life of the tiller, and solving the problem of hard soil blocks in some unrenovated land. When the tiller turns over such soil blocks, it is not only difficult to turn over, but also easy to cause wear to the shovel blade.

[0040] Embodiment 2: This embodiment is intended to promote the solution of the problem that the soil turning shovel can only be used to buffer the soil turning shovel in Embodiment 1, but cannot turn over the hard soil blocks. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 10 A watering assembly 141 is provided inside the tilling rod 115, and the watering assembly 141 includes a water storage space 142 opened in the tilling rod 115, and the water storage space 142 is located on the upper side of the piston cavity 119, and an air supply channel 143 is opened between the water storage space 142 and the piston cavity 119, and an air supply check valve 144 is provided in the air supply channel 143 near the water storage space 142, and the air supply check valve 144 is used to prevent gas backflow.

[0041] When the plow blade 116 encounters a harder soil block, the plow blade 116 and the handle 117 will move into the slot 118 of the tiller rod 115. The connecting rod 124 on the handle 117 drives the piston block 120 to slide upward in the piston chamber 119, so that the space of the piston chamber 119 becomes smaller, the gas in the chamber is compressed, and the air pressure increases. As the air pressure in the piston chamber 119 increases, when the air pressure reaches the opening pressure of the air supply check valve 144, the air supply check valve 144 opens. The high-pressure gas enters the water storage space 142 through the air supply channel 143, causing the air pressure in the water storage space 142 to increase rapidly. The increased air pressure is greater than the external atmospheric pressure, providing power for squeezing out the water in the water storage space 142 later.

[0042] See Figure 5-Figure 9 The watering assembly 141 also includes a groove 145 opened in the handle 117, a water outlet pipe 146 for discharging water is installed in the groove 145, a water supply pipe 147 is connected between the water outlet pipe 146 and the water storage space 142, one end of the water supply pipe 147 is fixedly connected to the water storage space 142, and the other end of the water supply pipe 147 is fixedly connected to the side of the water outlet pipe 146, and a sealing strip 148 for sealing the water outlet end of the water outlet pipe 146 is installed in the groove 145, and the sealing strip 148 is set as a rubber strip.

[0043] The water pipe 147 in this solution is set as a hose, so that the state of the water pipe 147 is not affected when the handle 117 cooperates with the soil turning rod 115. The sealing strip 148 is set to prevent mud from entering the water pipe 146 when the water pipe 146 is not opened in the groove 145, thereby avoiding the phenomenon of mud entering the water pipe 146 and causing blockage.

[0044] See Figure 8 A control disk 150 is installed on the side of the water outlet pipe 146, and a control gear 151 is fixedly installed on the outside of the control disk 150. A control rack 152 is installed in the slot 118 at a position corresponding to the control gear 151, and the control rack 152 is intermittently meshed with the control gear 151. A control shaft 153 is inserted into the control disk 150 and the control gear 151, and a torsion spring 154 is provided on the outer sleeve of the control shaft 153. One end of the torsion spring 154 is fixedly connected to the side of the control gear 151, and the other end of the torsion spring 154 is fixedly connected to the inner wall of the groove 145.

[0045] The control shaft 153 only plays a supporting role, and there is a certain distance between the control shaft 153 and the inner wall of the groove 145 , so the existence of the control shaft 153 does not affect the use of the torsion spring 154 .

[0046] When the plow blade 116 moves upward, the control gear 151 will be driven by the handle 117 to move upward. As the control gear 151 rises, it will contact and engage with the control rack 152. When the control gear 151 engages with the control rack 152, the upper part of the water outlet pipe 146 will be controlled to be pushed toward the inner wall of the groove 145, and the water outlet pipe 146 will flip outward. As the water outlet pipe 146 flips out, water will quickly eject from the bottom of the water outlet pipe 146, thereby impacting the soil blocks and changing the hardness of the soil.

[0047] After the water arrow is sprayed, if the plow blade 116 turns up the softened soil, the spring 123 is released, thereby pushing the handle 117 and the plow blade 116 to reset. At the same time, the air intake check valve 122 is opened, and the external gas enters the piston chamber 119 to achieve inflation. If the soil in the area still cannot be broken, the plow blade 116 remains retracted until it completely passes over the area and resets.

[0048] It should be noted that see Figure 7 The outlet pipe 146 is configured as a curved pipe so that the water falls as close as possible to the soil block near the tip of the plow 116. When the plow 116 moves downward in the slot 118, the control gear 151 is driven by the handle 117 to move downward, so that it is offset from the control rack 152. At this time, the torsion spring 154 is released, so that the control gear 151 and the outlet pipe 146 are reset, and the outlet pipe 146 returns to the groove 145.

[0049] Splash plates 155 are installed on both sides of the frame 111. A first water supply pipe 156 for replenishing water to the water storage space 142 is installed in the splash plates 155 and the frame 111. A plurality of second water supply pipes 157 are connected to the bottom of the first water supply pipe 156. One end of the second water supply pipe 157 is connected to the first water supply pipe 156, and the other end of the second water supply pipe 157 is connected to the water storage space 142. The first water supply pipe 156 and the second water supply pipe 157 are both configured as hoses, and a water supply check valve 158 is provided in the second water supply pipe 157.

[0050] See Figure 3 and Figure 6 By setting the splash plate 155, the range of the soil can be effectively controlled when the tiller is in operation. By setting the first water supply pipe 156 and the second water supply pipe 157, it is convenient to manually replenish water when the water storage space 142 lacks water. It should be added that the water inlet end of the first water supply pipe 156 is plugged into the splash plate 155, and the first water supply pipe 156 is externally threaded with an end cap for protecting and sealing the first water supply pipe 156.

[0051] The air supply check valve 144, the air intake check valve 122 and the water supply check valve 158 in this solution are all prior art, and the working principles are well known to those skilled in the art.

[0052] In this embodiment, the water storage space 142, the air supply channel 143, and the water outlet pipe 146 in the watering assembly 141 are arranged, and the piston block 120 and the piston chamber 119 cooperate so that when the plow blade 116 contacts a harder soil block, the gas in the piston chamber 119 will be pushed into the water storage space 142 through the air supply channel 143, and the air pressure in the water storage space 142 will change. At this time, the water in the water storage space 142 will be pressurized and will pass through the water supply pipe 147, and then from the water outlet pipe 14 6 is sprayed onto the soil blocks to soften the soil blocks and make it easier to turn them over. Then, by controlling the gear 151, the rack 152 and the torsion spring 154, the opening and closing of the water outlet pipe 146 are automatically controlled when the handle 117 and the turning rod 115 are in motion. Therefore, when the plow 116 encounters hard soil blocks, the resistance encountered by the plow 116 when turning the soil blocks is further reduced, reducing the damage to the plow 116, and at the same time speeding up the turning of the soil, thereby improving the overall turning of the soil efficiency.

[0053] Embodiment 3: This embodiment is intended to solve the problem that it may be inconvenient to turn the soil block after softening. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 6-Figure 11A track groove 160 for guiding the tool handle 117 is provided on the inner wall of the slot 118, a round block 161 is installed outside the tool handle 117, and the round block 161 is slidably engaged in the track groove 160. The track groove 160 includes a first groove body 162, a second groove body 163, a third groove body 164 and a fourth groove body 165. The second groove body 163 is located on one side of the first groove body 162, the fourth groove body 165 is located on the other side of the first groove body 162, and the third groove body 164 is located at the top of the second groove body 163 and the fourth groove body 165. The first groove body 162, the second groove body 163, the third groove body 164 and the fourth groove body 165 are arranged in sequence and connected to form a hexagonal arrangement, wherein the second groove body 163 and the fourth groove body 165 are arranged vertically.

[0054] Under normal conditions, the round block 161 outside the handle 117 is located in the first groove 162. When the plow 116 contacts a harder soil block, the round block 161 will enter the second groove 163 from the first groove 162. In the process of the round block 161 entering the second groove 163 from the first groove 162, the plow 116 flips over. In the process of flipping of the plow 116, the tip of the blade is always in contact with the soil block. Through the flipping of the plow 116 and the continuous pressure, the soil block is passively shoveled. Compared with shoveling the soil block at a single angle, this multi-angle shovel can more conveniently shovel the soil block.

[0055] When the plow cutter 116 is retracted, the round block 161 will enter the third slot 164 from the second slot 163. When the round block 161 enters the third slot 164, the plow cutter 116 will flip over and keep in contact with the soil block during flipping, thereby achieving the effect of drilling the soil.

[0056] During the resetting process, the round block 161 returns from the third slot body 164 through the fourth slot body 165 to the first slot body 162, so as to restore to the initial normal soil turning state.

[0057] In this embodiment: by setting the track groove 160 and the round block 161, and cooperating with the piston block 120, the piston chamber 119 and the spring 123, the effect of buffering the plow blade 116 and increasing the service life of the plow blade 116 is further improved, and when the handle 117 is slidably inserted in the slot 118, the rotation angle of the handle 117 can be triggered, so that the plow blade 116 can cut into the soil at multiple angles, reducing the direct impact on the plow blade 116, playing a buffering role, and at the same time can more effectively turn over the soil, further improving the turning effect.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
