Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco transplanting, and particularly relates to a multi-ridge pit digging machine. Background Art

[0002] Since tobacco transplanting requires the completion of the planting from seedling raising to the field in a relatively short time, and pit digging is required for field planting, the existing pit digging machines are all single-ridge pit digging machines and cannot meet the pit digging requirements in a relatively short time.

[0003] The single-ridge pit digging machine can dig 2 hectares of pits per day, and the pit digging efficiency is not high, which affects the progress of tobacco transplanting and misses the best transplanting period. Especially in the flat tobacco fields, the single-ridge pit digging machine reciprocates frequently and can only dig 2 ridges at a time, affecting the pit digging progress and further affecting the transplanting time, and cannot meet the transplanting requirements of tobacco within the appropriate period.

[0004] Prior Art One:

[0005] One wheel, a frame and a digging shovel are added to each side of the original single-ridge pit digging machine, and the two-wheel traction is changed to four-wheel traction to achieve simultaneous pit digging of 3 ridges.

[0006] Disadvantages of Prior Art One:

[0007] After adding one wheel to each side of the 1.20-meter wheelbase, the formed four-wheel frame is too wide, and the total wheelbase measured on site reaches 3.6 meters, which is not conducive to the traction and transportation of agricultural machinery.

[0008] Technical Solution of Prior Art Two

[0009] No wheel is added for traction on both sides of the single-ridge pit digging machine, and the frame is extended to install the digging shovel for simultaneous pit digging of 3 ridges.

[0010] Disadvantages of Prior Art Two:

[0011] The frame is extended by 0.8 meters on each side of the 1.20-meter wheelbase, and the width measured on site reaches nearly 3.0 meters. At the same time, the pit digging does not meet the requirements of the triangular seedling fixing for tobacco transplanting. Content of the Utility Model

[0012] The purpose of the utility model is to solve the defects existing in the above prior art and provide a multi-ridge pit digging machine.

[0013] In order to improve the pit digging efficiency, shorten the transplanting time, and complete the flue-cured tobacco field transplanting as much as possible during the best transplanting period, it is necessary to develop a multi-ridge pit digging machine, which can improve the pit digging efficiency, meet the requirements of the transplanting progress, complete the tobacco transplanting work within the best transplanting period, and is of great significance for promoting the early growth and rapid development of tobacco.

[0014] The utility model adopts the following technical solutions:

[0015] Multi-ridge pit digging machine, including a towing frame, a digging spade, a digging spade support, a ratchet wheel, a traveling wheel, a main transmission shaft, a bearing seat, a mounting seat at the end of the digging spade, a pin shaft, and a roller.

[0016] The bearing seat is installed on the lower side of the towing frame. The main transmission shaft is installed on the bearing seat through bearings. The traveling wheel is installed on the main transmission shaft. Ratchet wheels are installed in the middle and on both sides of the main transmission shaft. Three groups of mounting seats at the ends of the digging spades are installed on the upper side of the towing frame. A pin shaft is installed in any one of the mounting seats at the ends of the digging spades. The ends of the three digging spade supports all have sleeves, and the sleeves are sleeved on the pin shaft. Rollers linked to the ratchet wheels are installed on the lower sides of the three digging spade supports. When the roller moves to a certain specific position between the outer edge and the inner edge of the ratchet wheel and moves towards the inner edge, the digging spade contacts the ground. When the roller moves to a certain specific position between the outer edge and the inner edge of the ratchet wheel and moves towards the outer edge, the digging spade disengages from the ground. Digging spades are installed on the other sides of the three digging spade supports.

[0017] Digging spade I, digging spade II, and digging spade III respectively correspond to digging spade support I, digging spade support II, and digging spade support III. Digging spade support I, digging spade support II, and digging spade support III respectively correspond to ratchet wheel I, ratchet wheel II, and ratchet wheel III. Ratchet wheel I, ratchet wheel II, and ratchet wheel III are arranged with a 120° stagger from each other, so that digging spade I, digging spade II, and digging spade III do not dig pits simultaneously.

[0018] Furthermore, a towing connection hook is installed on one side of the towing frame.

[0019] Furthermore, the towing frame of the multi-ridge pit digging machine is obtained by extending the frame of the original single-ridge pit digging machine by 0.7 meters on both sides of the traveling wheel, so that the total length of the towing frame is 2.6 meters.

[0020] Furthermore, reinforcing frames are welded on the three digging spade supports. One end of a return spring is connected to the reinforcing frame, and the other end of the return spring is connected to the towing frame.

[0021] Advantages of the present utility model:

[0022] The present utility model can satisfy that the three digging spades do not dig pits simultaneously, form triangular seedling fixing and transplanting, and meet the requirements of tobacco leaf transplanting.

[0023] The present utility model adds one group of digging spades on each of the two sides of the single-ridge pit digging machine, and 6 ridges can be dug by reciprocating on the tobacco ridge. The single-ridge pit digging machine can only dig 2 ridges by reciprocating on the tobacco ridge. The single-ridge pit digging machine can complete the pit digging amount of 30 mu of land in a single day. The present utility model can achieve the goal of 90 mu in a single day, which is 60 mu more than the single-ridge pit digging machine per day, and the efficiency is increased by 2 times. The multi-ridge pit digging machine is 90 mu / day, 60 mu / day more than the single-ridge pit digging machine, and saves 480 yuan in cost per day.

[0024] The teeth of the ratchet wheel of the present utility model are installed with a 120° stagger, so that digging spade I, digging spade II, and digging spade III do not dig pits simultaneously, and the tobacco ridges do not affect each other. Description of the Drawings

Specific embodiments

[0031] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] Such as Figures 1-5 shown, the multi-ridge pit digging machine of the present utility model includes a towing frame 1, a grub hoe, a grub hoe support, a ratchet, a road wheel 9, a main transmission shaft 10, a bearing seat 13, a grub hoe end mounting seat 14, a pin shaft 15, and a roller 18.

[0033] The bearing seat 13 is installed on the lower side of the towing frame 1. The main transmission shaft 10 is installed on the bearing seat 13 through bearings. The driving wheels 9 are installed on the main transmission shaft 10. Ratchets are installed in the middle and on both sides of the main transmission shaft 10. The rotation of the driving wheels 9 drives the rotation of the main transmission shaft 10, thereby driving the rotation of the ratchets. Three groups of installation seats 14 for the ends of the digging shovels are installed on the upper side of the towing frame 1. A pin shaft 15 is installed in any one of the installation seats 14 for the ends of the digging shovels. Sleeves are provided at the ends of the three digging shovel supports. The sleeves are sleeved on the pin shaft 15, enabling the digging shovel supports to rotate up and down around the pin shaft 15. Rollers 18 linked to the ratchets are installed on the lower sides of the three digging shovel supports. The rotation of the ratchets drives the rollers to roll back and forth between the outer edge and the inner edge of the ratchets, thereby enabling the digging shovel supports to rotate up and down. When the rollers move to a certain specific position between the outer edge and the inner edge of the ratchets and move towards the inner edge, the digging shovels contact the ground to complete the work of digging pits. When the rollers move to a certain specific position between the outer edge and the inner edge of the ratchets and move towards the outer edge, the digging shovels are separated from the ground. Digging shovels are installed on the other sides of the three digging shovel supports.

[0034] The digging shovel I 2, the digging shovel II 4, and the digging shovel III 6 respectively correspond to the digging shovel support I 3, the digging shovel support II 5, and the digging shovel support III 7. The digging shovel support I 3, the digging shovel support II 5, and the digging shovel support III 7 respectively correspond to the ratchet I 8, the ratchet II 11, and the ratchet III 12. The ratchet I 8 on the left, the ratchet II 11 in the middle, and the ratchet III 12 on the right are staggered from each other by 120° (that is, when the roller of the ratchet I 8 and the digging shovel support I 3 is at the outermost edge of the ratchet, the roller of the ratchet II 11 and the digging shovel support II 5 is between the outer edge and the inner edge of the ratchet, while the roller of the ratchet III 12 and the digging shovel support III 7 is at the inner edge of the ratchet), so that the digging shovel I 2, the digging shovel II 4, and the digging shovel III 6 do not dig pits simultaneously.

[0035] Furthermore, a towing connection hook is installed on one side of the towing frame 1, which is convenient for connecting with a tractor. (As Figure 3 shown)

[0036] Furthermore, the towing frame 1 of the multi-ridge pit-digging machine is improved on the basis of the original single-ridge pit-digging machine. Specifically, the towing frame 1 of the original single-ridge pit-digging machine is extended 0.7 meters to both sides of the driving wheels 9. The total length of the towing frame 1 is 2.6 meters.

[0037] Furthermore, reinforcing frames 16 are welded on the three digging shovel supports. One end of the return spring 17 is connected to the reinforcing frame 16, and the other end of the return spring 17 is connected to the towing frame 1. The function of the return spring 17 is to provide a return elastic force. When the rollers roll from the outer edge of the ratchets to the concave part, the impact force of the digging shovels falling from the highest position and the return elastic force provided by the return spring 17 enable the digging shovels to insert into the soil to a certain depth.

[0038] The working process of the present utility model:

[0039] Transfer the present utility model to the field, connect the present utility model with machinery such as a tractor, and start the tractor. Under the traction of the tractor, the driving wheels 9 contact the ground, driving the main transmission shaft 10 to rotate. The main transmission shaft 10 drives three ratchets to rotate, and the three ratchets drive three rollers to move. Since the rollers move back and forth between the outer edge and the inner edge of the ratchet, when moving from the outer edge to the inner edge, the digging spade is inserted into the soil by the impact of the rollers and the resilience of the spring. Therefore, the digging spade support connected thereto is driven to move up and down in a reciprocating manner. At the same time, since the three ratchets are installed with a 120-degree stagger, the three rollers will drive the three digging spades to dig the ground at different times. Since three digging spades are installed, the present utility model can complete the workload of digging pits for 90 mu of land per day.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
