[0027] The loosening member 101 includes a fender 101a, a blade 101b disposed behind the fender 101a, and a power shaft 101c drivingly connected to the blade 101b.

[0028] Preferably, when the loosening member 101 is working, the blade 101b is driven by the tractor power shaft 101c to perform rotational motion on the one hand, and performs constant speed linear motion along with the forward movement of the unit on the other hand. During the soil cutting process, the blade 101b first cuts off the soil, throws it toward and hits the support plate 101d and the fender 101a, and then falls back to the ground after being crushed. The unit continuously moves forward to loosen the uncultivated land. The rotating blade shaft 101g and the blade 101b are the main working parts of the rotary tiller. The rotating blade shaft 101g is mainly used to transmit power and install the blade 101b. Common blades 101b include curved, chisel-shaped and right-angled blades. The blade we selected is a right-angled blade;

[0029] Unlike the large rotary tillers and small walk-behind rotary tillers in the prior art, the rotary tiller in the present invention is automatically advanced. The size selection of the blade 101b is crucial, which is related to whether the machine can achieve the above functions. After comparing the blade 101b size table, we finally chose the West Asia 3.5 type rotary tiller blade. The appropriate size can fully mill the soil when the motor can drive it. The number of blades 101b is determined to be 12, and every 2 right-angle blades are as follows Figure 4 Shown is one piece, with two pieces forming a group, for a total of 5 groups, with one piece on each side of the mudguard 101a, to ensure uniform soil operation, with a spacing of 4mm between each blade to ensure non-conflicting mutual operation of each blade, so that the overall width exceeds the mulch covering area.

[0030] The fender 101a is used to prevent soil from splashing and further breaking, and can also protect the safety of maintenance personnel and improve working conditions.

[0031] Furthermore, the loosening member 101 is a rotary tiller, which can be divided into horizontal axis type, vertical axis type and oblique axis type according to the position of the rotary tiller shaft; can be divided into traction type, hanging type and direct connection type according to the connection method with the tractor; can be divided into intermediate transmission type and side transmission type according to the transmission method of the shaft. The side transmission type can be divided into two types: side gear transmission and side chain transmission. The utility model adopts the side chain transmission method to transmit the rotating shaft 101g.

[0032] A support plate 101d is fixedly arranged above the mudguard 101a, a rotating shaft 101e is transmission-arranged above the support plate 101d, the rotating shaft 101e is transmission-connected to the power shaft 101c, a accommodating frame 101f is movably arranged on one side of the rotating shaft 101e, a rotating knife shaft 101g is movably arranged in the accommodating frame 101f, and the rotating knife shaft 101g is fixedly connected to the blade 101b.

[0033] Preferably, the rotating cutter shaft 101g is made of a seamless smooth tube, with shaft heads welded at both ends of the shaft for connecting with the left and right support arm pins, and a cutter seat or cutter disc welded on the shaft, and the cutter seat is welded on the rotating cutter shaft 101g in a spiral arrangement for installing the blade 101b; there are holes with equal spacing around the cutter disc for fixing the blade 101b.

[0034] A frame 101h is arranged below the accommodating frame 101f, and an adjusting block 101i is arranged above the frame 101h. A sliding groove 101p is opened in the adjusting block 101i, and a sliding block 101k is slidingly arranged in the sliding groove 101p. An extension plate 101n is fixedly connected to the outer wall of the sliding block 101k, and the extension plate 101n is rotatably connected to the rotating knife shaft 101g and the rotating shaft 101e respectively.

[0035] Preferably, by cooperating with the slider 101k and the slide groove 101p, when it is necessary to adjust the position of the rotating knife shaft 101g and the blade 101b, the installed bolts are removed, and the height of the rotating knife shaft 101g and the blade 101b can be adjusted by adjusting the position of the slider 101k correctly; the extension plate 101n is located between the accommodating frame 101f and the mudguard 101a, and the accommodating frame 101f is provided with a chain and sprocket for driving the rotating knife shaft 101g and the rotating knife shaft 101g.

[0036] A mounting frame 107 is fixedly provided above the trenching member 102. The trenching member 102 includes a retaining block 102a, a flat soil groove 102b provided below the retaining block 102a, and a trenching slope 102c provided on the side wall of the retaining block 102a.

[0037] Preferably, the retaining block 102a is provided with a motor, a gearbox and a power shaft 101c. When in use, the power output of the motor is transmitted to the rotary tiller power meshing gear, and the meshing transmitted by the rotary tiller is separated, and the power is transmitted to the rotary tiller, and then transmitted to the high-speed rotating cutter shaft 101g through a chain. Through the high-speed rotation of the blade 101b, the soil and weeds are rotary tilled in the soil to achieve the loose and granular structure of the soil. During operation, the blade 101b rotates at a certain speed and advances with the group, cutting, crushing and throwing the soil backward, and then dragging it flat. The rotary tiller should travel at a low speed, and the power output shaft is driven to make the blade 101b on the rotary cutter shaft 101g cut the soil block, crush and drag it flat. Through the gearbox conversion, the power shaft 101c speed is increased, and the soil block is broken by the blade 101b.

[0038] Example 2

[0039] Reference Figure 1~Figure 5, which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that this embodiment further provides a mulching machine, including a first bracket 103a fixedly arranged on a mounting frame 107 and a second bracket 103d arranged behind the first bracket 103a, and the roller member 103 includes a first roller 103b movably connected to the first bracket 103a and a second roller 103c movably connected to the second bracket 103d.

[0040] Preferably, the second roller 103c includes two small roller shafts.

[0041] The film pressing member 104 includes a first roller 104 a and a second roller 104 b which are arranged on both sides of the mounting frame 107 . The first roller 104 a and the second roller 104 b are rotatably connected to the mounting frame 107 .

[0042] The covering member 105 includes a first covering block 105a, a second covering block 105b symmetrically arranged with respect to the first covering block 105a, and covering slopes 105c respectively opened on the outer walls of the first covering block 105a and the second covering block 105b. The first covering block 105a and the second covering block 105b are fixedly connected to the mounting frame 107.

[0043] Preferably, the covering slope 105c on the first covering block 105a and the covering slope 105c on the second covering block 105b are inclined inward, that is, when the covering member 105 moves forward, the soil in the first covering block 105a and the second covering block 105b will be pushed toward the middle by the covering slope 105c and cover the two sides of the film.

[0044] The covering member 105 includes a mounting plate 106 b and a film cutting block 106 c arranged on the end surface of the mounting plate 106 b , wherein a limit rod 106 a is slidably arranged on the outer wall of the mounting plate 106 b , and the limit rod 106 a is fixedly connected to the mounting frame 107 .

[0045] Preferably, the mounting disk 106b is slidably connected to the limit rod 106a, and a motor and a control module for controlling the up and down movement of the mounting disk 106 are connected inside the mounting disk 106. The up and down movement of the mounting disk 106 is controlled by the operator by issuing different instructions, so that the film is cut off when the mounting disk 106 moves downward.

[0046] Preferably, the following motor scheme is selected according to the characteristics that the agricultural drive wheel has a low rotation speed and a large torque transmitted, and the rotary tiller has a high rotation speed and a relatively small torque transmitted:

[0047] The driving wheel adopts a rear axle motor and the rotary tiller is driven by a DC speed regulating motor. The DC speed regulating motor has its own power supply and does not need to be plugged in. It can meet the working conditions of the rotary tiller, and the rear axle motor meets the driving requirements of the overall machinery.

[0048] The utility model adopts a motor drive, and the electric bridge is controlled by a remote wireless remote control, so as to control the overall forward and backward movement. In this way, the rear film laminating machine is connected. In front of the driving center, we will also install a rotary tiller, that is, the control part of the loosening piece 101 and the furrowing piece 102. In the utility model, a nine-tooth transmission shaft is used to connect the rotary tiller and the control motor to achieve the effect of transmitting power. In order to prevent the rotary tiller from entering the ground at the beginning and the ground film is laid as soon as it enters the ground, and the rotary tiller continues to move when it leaves the ground at the end, the rear axle motor and the control part of the rotary tiller in the utility model are controlled separately, so as to achieve the purpose of stopping the two parts separately at any time.

[0049] In summary, the roller part 103, the film pressing part 104, the soil covering part 105 and the soil covering part 105 are referred to as the film laying part in the utility model. The whole film laying part is rear-mounted and is connected to the rear axle motor by a three-point suspension mechanism. Before the film laying machine starts working, the rear axle motor is started first, and the operator feeds the film into the roller part 103, and the roller part 103 pulls out a certain length of film. After the film laying starts, the film is pulled out by the roller part 103 and dragged away with the forward power of the film laying machine. The loosening part 101 and the film pressing part 104 in front rotate with the forward power of the tractor, and press the film and cover the soil. The soil covering part 105 realizes soil pressing on both sides of the film. After the one-way operation is completed, the linear motor film cutting device is started to drive the saw blade to realize linear motion and cut the film. After the film is cut, the saw blade automatically returns and the DC motor is turned off at the same time. When a new stroke begins, the film is still in the roller member 103. After starting its DC motor, there is no need for personnel to feed the film into the single-roller mechanism. The film laying can be successfully completed by repeating other actions.
